This article is part of the God object resolution series. To illustrate it, we use a running example through the whole series. This article is the first step of the resolution.
In the current state, the God object contains the code of various features. We want instead to have separate features to build on, in other words to extract the code into new features.
Dispatching the code can take a lot of time, but it can be done iteratively through small steps. The first step is to extract 1 method:
/** Add a new {@link Employee} and returns its ID. */
public int hireEmployee(Employee employee) {
int employeeId = ++nextEmployeeId;
employees.put(employeeId, employee);
return employeeId;
}
interface Employer {}
class EmployerImpl implements Employer {}
The interface can help for testing.
It also allows to apply the Dependency inversion principle.
It will be particularly useful if you want to transform the God object into a façade.
We didn't give much thought for the name of the class because we don't know the implementation details yet.
We will come back on that later.
For now, this new class should only be used inside the God object, so it is not an issue and we will come back on that later.
interface Employer {
public int hireEmployee(Employee employee);
}
class EmployerImpl implements Employer {
/** Add a new {@link Employee} and returns its ID. */
public int hireEmployee(Employee employee) {
int employeeId = ++nextEmployeeId;
employees.put(employeeId, employee);
return employeeId;
}
}
Notice that the code might not compile.
In our example, nextEmployeeId
and employees
do not exist yet in the Employer
class.
What you should pay attention to at this stage is the state dependencies, like these two fields.
You may copy them too, but you break the integrity of the God object state.
For instance, hiring an employee through EmployerImpl
fills the EmployerImpl.employees
map, but not the EmployeeManager.employees
map.
Consequently, firing the employee
from EmployeeManager
, method which has not been extracted yet, won't work properly because it will remove nothing.
To fix that, you may copy all the methods which depend on this state at once, but these methods may rely on other pieces of the state, which relate to other methods, which relate to other fields, and so on.
Rather, you may use functional interfaces of the java.util.function
package, like Supplier
, to interact with the God object state:
class EmployerImpl implements Employer {
private final Supplier<Integer> newEmployeeID;
private final Supplier<Map<Integer, Employee>> employeeMap;
public EmployerImpl(Supplier<Integer> newEmployeeID, Supplier<Map<Integer, Employee>> employeeMap) {
this.newEmployeeID = newEmployeeID;
this.employeeMap = employeeMap;
}
/** Add a new {@link Employee} and returns its ID. */
public int hireEmployee(Employee employee) {
int employeeId = newEmployeeID.get();
employeeMap.get().put(employeeId, employee);
return employeeId;
}
}
class EmployeeManager {
private int nextEmployeeId = 0;
private final Map<Integer, Employee> employees = new HashMap<>();
private final Employer employer = new EmployerImpl(() -> ++nextEmployeeId, () -> employees);
...
}
Notice that the first Supplier
is not a mere accessor: it also take in charge the increment required to update the state.
class EmployeeManager {
...
/** Add a new {@link Employee} and returns its ID. */
public int hireEmployee(Employee employee) {
return employer.hireEmployee(employee);
}
...
}
At this point, you can run the tests of the God class: they should all be green and the coverage should cover both the God class and the feature class.
In our case, both EmployeeManager
and EmployerImpl
have a 100% line coverage.
We only extracted a single method, but in a retrocompatible way.
Consequently, you can stop there and come back later to continue your refactoring.
Understanding that you can do such a small step one at a time is important to not be overwhelmed when dealing with a massive God object.
You should always keep in mind that you can go one method at a time without breaking anything.
This process should of course be iterated until all the methods have been extracted.
In particular, you should not pass to the next phase before this one is complete.
As you saw, the new feature class may build on Supplier
instances and other tricks to interact with the state of the God object.
In other words, we extracted the logics, but not the state, and the God object won't be completely refactored before the state is also extracted.
But before to extract it, we should extract all the methods.
By repeating the previous steps on the firing method, we extract it to the same Employer
class.
We reuse the employeeMap
already available for the state:
class EmployerImpl implements Employer {
...
/** Fire an {@link Employee} and returns its ID. */
public Employee fireEmployee(int employeeID) {
return employeeMap.get().remove(employeeID);
}
}
class EmployeeManager {
...
/** Fire an {@link Employee} and returns its ID. */
public Employee fireEmployee(int employeeID) {
return employer.fireEmployee(employeeID);
}
...
}
For the other methods, we will create new features. For instance, the personal details should contain the address and phone number methods:
interface EmployeeDetails { // New feature interface
public Address getAddress(int employeeID);
public void setAddress(int employeeID, Address address);
public String getPhoneNumber(int employeeID);
public void setPhoneNumber(int employeeID, String phoneNumber);
}
class EmployeeDetailsImpl implements EmployeeDetails { // New feature class
private final Supplier<Map<Integer, Address>> addressesMap;
private final Supplier<Map<Integer, String>> phonesMap;
public EmployeeDetailsImpl(Supplier<Map<Integer, Address>> addressesMap, Supplier<Map<Integer, String>> phonesMap) {
this.addressesMap = addressesMap;
this.phonesMap = phonesMap;
}
/** Return the {@link Address} of the given {@link Employee}. */
public Address getAddress(int employeeID) {
return addressesMap.get().get(employeeID);
}
/** Change the {@link Address} of the given {@link Employee}. */
public void setAddress(int employeeID, Address address) {
addressesMap.get().put(employeeID, address);
}
/** Return the phone number of the given {@link Employee}. */
public String getPhoneNumber(int employeeID) {
return phonesMap.get().get(employeeID);
}
/** Change the phone number of the given {@link Employee}. */
public void setPhoneNumber(int employeeID, String phoneNumber) {
phonesMap.get().put(employeeID, phoneNumber);
}
}
class EmployeeManager { // Updated God object
...
private final Map<Integer, Address> addresses = new HashMap<>();
private final Map<Integer, String> phoneNumbers = new HashMap<>();
private final EmployeeDetails details = new EmployeeDetailsImpl(() -> addresses, () -> phoneNumbers);
...
/** Return the {@link Address} of the given {@link Employee}. */
public Address getAddress(int employeeID) {
return details.getAddress(employeeID);
}
/** Change the {@link Address} of the given {@link Employee}. */
public void setAddress(int employeeID, Address address) {
details.setAddress(employeeID, address);
}
/** Return the phone number of the given {@link Employee}. */
public String getPhoneNumber(int employeeID) {
return details.getPhoneNumber(employeeID);
}
/** Change the phone number of the given {@link Employee}. */
public void setPhoneNumber(int employeeID, String phoneNumber) {
details.setPhoneNumber(employeeID, phoneNumber);
}
}
At some point, we consider that the setEmployee(employeeID, Employee)
is also about the update of the details of the employee.
The difference with the address and the phone number is that we update a more complete structure.
We can see, with the current implementation, that addresses and phones are not part of the employee
, since we store them separately.
In other words, the employee
probably provides complementary information.
Let's say that it contains contractual details, like the content of the contract, the date of signature, etc.
With that in mind, we can think that a mere "setEmployee" is not clear enough, and we choose to rename it "setContract".
Extracting the setEmployee
method thus leads us to this result:
interface EmployeeDetails { // Add the renamed method
...
public Employee setContract(int employeeID, Employee employee);
}
class EmployeeDetailsImpl implements EmployeeDetails { // Add the renamed method and state supplier
...
private final Supplier<Map<Integer, Employee>> contractsMap;
public EmployeeDetailsImpl(..., Supplier<Map<Integer, Employee>> contractsMap) {
...
this.contractsMap = contractsMap;
}
...
/**
* Replace the {@link Employee}'s contractual details and returns the previous
* version.
*/
public Employee setContract(int employeeID, Employee employee) {
return contractsMap.get().put(employeeID, employee);
}
}
class EmployeeManager { // Add the state accessor and rewrite the method.
...
private final EmployeeDetails details = new EmployeeDetailsImpl(..., () -> employees);
...
/** Replace the {@link Employee}'s details and returns the previous version. */
public Employee setEmployee(int employeeID, Employee employee) {
return details.setContract(employeeID, employee);
}
...
}
Notice that the God object still have the old method name, but the new feature uses the new one.
This way, when the God object will be replaced by the feature, we will have a clearer method to use.
We may go further with the Employee
parameter of this method, where using a Contract
class seems more relevant.
You may create for example a new Contract
interface, and create an adapter from Employee
to Contract
.
You should then adapt employee
into a contract
before to call setContract(contract)
.
The state accessor should also be adapted, which requires to adapt the contract
into an employee
.
This is out of our scope, so we don't do it here and we don't go further in details, but it is possible.
getEmployee
can also be extracted in the same way:
interface EmployeeDetails {
...
public Employee getContract(int employeeID);
}
class EmployeeDetailsImpl implements EmployeeDetails {
...
/** Return the {@link Employee}'s contractual details. */
public Employee getContract(int employeeID) {
return contractsMap.get().get(employeeID);
}
}
class EmployeeManager {
...
/** Return the {@link Employee}'s details. */
public Employee getEmployee(int employeeID) {
return details.getContract(employeeID);
}
...
}
Now, the only remaining methods are the ones related to the salary, which we extract in a new feature:
interface SalarySettings {
public void setSalary(int employeeID, double salary);
public double getSalary(int employeeID);
public void raiseSalary(int employeeID, double amount);
}
class SalarySettingsImpl implements SalarySettings {
private final Supplier<Map<Integer, Double>> salariesMap;
public SalarySettingsImpl(Supplier<Map<Integer, Double>> salariesMap) {
this.salariesMap = salariesMap;
}
/** Change the salary of the given {@link Employee}. */
public void setSalary(int employeeID, double salary) {
salariesMap.get().put(employeeID, salary);
}
/** Return the salary of the given {@link Employee}. */
public double getSalary(int employeeID) {
return salariesMap.get().get(employeeID);
}
/** Raise the salary of the given {@link Employee}. */
public void raiseSalary(int employeeID, double amount) {
Map<Integer, Double> salaries = salariesMap.get();
salaries.put(employeeID, salaries.get(employeeID) + amount);
}
}
class EmployeeManager {
...
private final Map<Integer, Double> salaries = new HashMap<>();
private final SalarySettings salarySettings = new SalarySettingsImpl(() -> salaries);
...
/** Change the salary of the given {@link Employee}. */
public void setSalary(int employeeID, double salary) {
salarySettings.setSalary(employeeID, salary);
}
/** Return the salary of the given {@link Employee}. */
public double getSalary(int employeeID) {
return salarySettings.getSalary(employeeID);
}
/** Raise the salary of the given {@link Employee}. */
public void raiseSalary(int employeeID, double amount) {
salarySettings.raiseSalary(employeeID, amount);
}
}
At that point, all the methods have been extracted and the initial state of the God object is not used anymore but to feed them. We can now start to dispatch this state to the relevant features.

The PAL Task Learning component, called Adept, provides learning-by-demonstration technology to enable the automation of routine or time-consuming tasks, thus freeing users to focus on more cognitively demanding activities.
The core of the Adept task learning component system is a module called LAPDOG (Learning Assistant Procedures from Demonstration, Observation, and Generalization). Given a demonstration consisting of a sequence of actions performed by a user to achieve a particular task, LAPDOG generalizes the action sequence into an executable procedure for achieving similar tasks in the future. LAPDOG subscribes to a dataflow model in which actions are characterized by their inputs and outputs, and action outputs serve as inputs to succeeding actions. Procedure generalization includes ensuring that every action input is supported by a previous output.
LAPDOG performs parameter generalization, generating a replacement of constants with variables or (accessor/construction) expressions over variables that reflect the dataflow observed in the demonstration. This generalization enables procedures to be reused in different situations and to different effect. LAPDOG also performs structure generalization, inducing loops over collections of objects by identifying and generalizing the repeated sequences of actions in the demonstration. LAPDOG's loop-induction algorithm supports advanced features such as learning loops over both ordered and unordered collections of objects and loops that process multiple lists simultaneously. Parameter and structure generalization are performed synchronously, so LAPDOG can learn loops over collections nested to arbitrary depth, and loops over collections that are the output of previous loops.
LAPDOG can learn from a single example, through the use of heuristics for filtering the set of alternative generalization hypotheses to a single best generalization. But it can also exploit the availability of multiple demonstrations to improve the quality of the learned procedure.
Learned procedures are executed by the Lumen agent framework, which is derived from the SRI Procedural Agent Realization Kit (SPARK). Lumen's hierarchical representation of tasks combined with instrumentation of task execution makes it possible to teach procedures that in turn invoke other learned procedures. This task composition enables incremental development of modular libraries of interdependent procedures.
Adept includes an interactive editor that enables users to visualize and modify learned procedures. The editor facilitates understanding and sharing of procedures by providing the means for a user to inspect a procedure's structure before executing it. It also permits users to adapt learned procedures quickly rather than demonstrating them again from scratch to incorporate changes.
Adept is application-independent. Its use within a particular application requires the definition of an action model that provides a semantic specification of individual actions in the application along with implementation of corresponding mechanisms for instrumenting and automating those actions. In essence, the action model provides the basic building blocks from which learned procedures are created. Applications interact with the task learning technologies via a bridge module through which all communication (i.e., instrumentation events and automation requests) flows.
Because of its dataflow model, the PAL task learning component is well suited to applications whose actions can be framed as operating on objects in the environment, and the effects of the actions can be captured in terms of action outputs that generally serve as inputs to succeeding actions. In its current form, the PAL task learning component is not well suited to applications whose actions are best captured in terms of their effects on the environment rather than in terms of the data they produce and consume. This is discussed in the Client Application Guide - Action Model section.

'They are being further traumatised': Plans to house 13 female asylum seekers on Achill Island postponed
by By Vivienne ClarkeA member of a welcome committee set up to support asylum seekers due to arrive on Achill Island has said that “anybody with a heart would have to reconsider” opposing the housing of vulnerable women in a local hotel.
James McNamara said he was very disappointed that the Department of Justice had changed its mind about its plan to house asylum seekers at a hotel on the Mayo island.
Some 13 female asylum seekers were due to arrive at the Achill Head Hotel today but the Department of Justice confirmed yesterday it had postponed their arrival.
In a statement it said: “The Department of Justice and Equality had hoped to transfer 13 vulnerable women to the Achill Head Hotel.
"The hotel was to provide emergency short-term accommodation to women who have come to Ireland seeking international protection.
"They were to be in Achill for a maximum stay of three months.
"However, an ongoing protest remains in place outside the hotel, so the Department has regrettably decided that, at the moment, to ask the women to move there would not be in their best interests, as they may be vulnerable while awaiting decisions on their protection applications”.
Mr McNamara told RTÉ radio’s Morning Ireland that while there was a “justifiable sense of anger” at the lack of consultation, he knew “in their hearts Achill people are generous.”

However, he said he feared that Achill people are “being stalked by outside forces with their own agenda.”
He said he did not recognise the faces of any of the protestors on television coverage.
“I believe outside influences are adding fuel to the fire. I don’t really know who’s involved.”
Mr McNamara said he was very upset by the protests as Achill has a long history of welcoming people from all over the world and there is also a very large Achill diaspora.
“There’s hardly a family in Achill without an emigrant in their midst.
“It is rather ironic.”
It was very sad that “these unfortunate women” fleeing from very difficult situations were now aware that they could not come to Achill because of the protests.
They are being further traumatised.
No one is in favour of direct provision, it will be the Magdalene Laundries of this generation, he predicted.
If the situation had been handled better there would have been a tremendous welcome for the women.
It was a very difficult question how the Department of Justice should have handled the issue, added Mr McNamara.
“It is something the experts should be handling.”
He was also concerned that no representative of the welcome committee was involved in a meeting between the department and community representatives held on Wednesday night.
Protests took place outside the hotel where that meeting took place.
“It’s a rather sad situation.”

For OpenElections volunteers coming to NICAR in Atlanta next month, we've got a challenge for you: help us tackle Georgia election results.
As we did last year in Baltimore, OpenElections will hold an event on Sunday, March 8, with the goal of writing scrapers and parsers to load 2000-2014 election results from the Peach State, and we're looking for some help. It's a great way to get familiar with the project and see what our processes are.
Georgia offers some different tasks, from scraping HTML results to using our Clarify library to parse XML from more recent elections. So we're looking for people who have some familiarity with Python and election results, but we're happy to help guide those new to the process, too. Thanks to our volunteers, we've already got a good record of where election result data is stored by the state.
Here's how the process will work: we'll start by reviewing the state of the data - what's available for which elections - and then start working on a datasource file that connects that data to our system. After that, we'll begin writing code to load results data, using other states as our models. As part of that process, we'll pre-process HTML results into CSVs that we store on Github.
If you're interested in helping out, there are two things to do: first, let us know by emailing<EMAIL_ADDRESS>or on Twitter at @openelex. Second, take the time to setup the development environment on your laptop following the instructions here. We're looking forward to seeing you in Atlanta!

Yep I love Nik software. I guess it comes from being introduced to color control points in Nikon/Nik Capture NX. I find most of their products worthwhile if you have a need for local adjustments, color effects filters, the best black and white conversions, noise reduction, and specialized sharpening. Now Nik has entered the HDR game. As usual the list price is outrageous for a plug-in but knowing Nik if HDR is your "thing" their product is probably killer.
As soon as I can get my hands on a copy I will do one of my mini-reviews. As you know i am not an HDR guy but acknowledge that a bunch of photographers out there are, so I thought you might be interested in this. Let's hope it will give the other guys a kick in the pants for some better HDR competition out there in HDR land. Here is the announcement from Nik. And here is where to get some other their other products.


Java¶
One of the cool feature of CookCC is being able to directly specify the lexer/parser right in the Java code using annotation, without going into an obscure / proprietary input file.
Why Java Annotation¶
You can look at CookCC presentation slides for more detailed comparisons and a quick tutorial.
Java Annotation vs Lex/Yacc¶
The main benefit of using Java annotation is that you can take full advantages of modern IDEs without having to deal with proprietary text files.
- syntax highlighting
- context sensitive hints
- code usage analysis
- refactoring
- auto-completion
- instant error checking
- etc
So it takes a lot of pain away from writing lexer / parsers.
This approach can be extended to other languages, such as Python or C#, even C / C++.
Java Annotation vs JavaDoc¶
Although it is possible to use JavaDoc doclet to extract annotations, the annotation capabilities of Java 1.5 is simply a lot easier to use and deal with. For this reason, I settled to use Java 1.5. This however, does not mean the code generated has to be run under JVM 1.5+. One can always target the output class files for earlier versions of JVM.
Annotation Processing API Changes¶
It should be note that Annotation Processing Tool (APT) was deprecated in Java 7. The newer java compiler based processing API was available since Java 6.
CookCC 0.3.3 only supports the older APT. CookCC 0.4+ supports the newer API (although I kept the old API code, but it was not used for any newer features introduced in 0.4+). If you cannot use Java 6 and later JDK, then you will have to use CookCC 0.3.3.
Overview¶
The following example is a simple calculator script interpreter adapted from A Compact Guide to Lex & Yacc.
Setup¶
First, add CookCC jar file to your project path. This jar file is only required for building the parser, and setting up the ant task. It is not required at runtime.
First Step: Annotate a Class¶
@CookCCOption
is used to mark a class that uses the generated
lexer/parser. In the following example, we mark the Calculator
class.
import org.yuanheng.cookcc.*;
@CookCCOption (lexerTable = "compressed", parserTable = "compressed")
public class Calculator extends Parser
{
// code
}
The generated class is actually the parent class of Calculator
, in
this case, Parser
class (which needs to be in the same package as
Calculator
). Since we haven’t really generated this class yet, so
what we needed to do to work on the Calculator
class without the
error in editor (assuming that you are using a decent Java IDE such as
Eclipse or IntelliJ IDEA) is to create an empty Parser.java
like the
following code.
/* Copyright (c) 2008 by Heng Yuan */
import org.yuanheng.cookcc.CookCCByte;
/**
* @author Heng Yuan
* @version $Id$
*/
public class Parser extends CookCCByte
{
}
Notice that we have the file header (copyright notice) and the class
header. CookCC Java input will keep these in the generated class. It
also keep the scope of the class, public
in this case. In general
as a good practice though, the generated class should be in the same
package of Calculator
, and in the package scope.
CookCCByte
is class that contains all the possible generated
functions (not all of them will be available depending on the options
and the patterns/rules), so that code in Calculator
can use them in
advance. Since we are not dealing with Unicode, so we extend
CookCCByte
class. For lexers that deal with Unicode, extend
CookCCChar
class.
Note that all the CookCC annotations and CookCCByte
are merely
required for compile time, they are not required for runtime. The
generated class no longer extends CookCCByte
.
Second Step: Mark a Token Enum¶
If you are only going to use a lexer, you can skip this section.
Within Calculator
class, you can specify the token
Enum
class. It is not required to have this Enum as a nested class of
Calculator
since @CookCCOption
can be used to specify the Enum
class defined elsewhere. However, I personally find that having such
nested declaration makes it more visual.
Use @CookCCToken
to mark a Enum declaration. All the names defined
here are all treated as terminals by CookCC.
To specify the precedence and the type, mark a token with
@TokenGroup
and set its type to LEFT, RIGHT or NONASSOC. If the type
is not specified, it is assumed to be NONASSOC. All unmarked tokens
would inherit the precedence and type of the previous token.
You can use static
import
to avoid typing TokenType.LEFT
and only need to type LEFT
. I
dislike static import, and I copy/paste code anyways. So it doesn’t
really matter.
@CookCCToken
static enum Token
{
@TokenGroup
VARIABLE, INTEGER, WHILE, IF, PRINT, ASSIGN, SEMICOLON,
@TokenGroup
IFX,
@TokenGroup
ELSE,
@TokenGroup (type = TokenType.LEFT)
GE, LE, EQ, NE, LT, GT,
@TokenGroup (type = TokenType.LEFT)
ADD, SUB,
@TokenGroup (type = TokenType.LEFT)
MUL, DIV,
@TokenGroup (type = TokenType.LEFT)
UMINUS
}
One of the unfortunate drawback of using Enum token is that it is
necessary to give a name to terminals such as '='
'<'
, etc. On
the other hand, it is good to have them defined since it is easier to
use them in abstract syntax trees (ASTs).
(Currently, CookCC does not have a tree generator yet. Hopefully it can be added in the near future.)
Lexer Section¶
Specifying Shortcuts¶
@Shortcut
is used to specify a single frequently used pattern can be
re-used in actual lexical patterns. Multiple @Shortcut
can be
defined using @Shortcuts
annotation. Just specify it on any
functions. The order of shortcut is not important and it is possible to
contain references to other shortcuts. Just be careful not to create
cyclic references.
@Shortcuts ( shortcuts = {
@Shortcut (name="nonws", pattern="[^ \\t\\n]"),
@Shortcut (name="ws", pattern="[ \\t]")
})
@Lex (pattern="{nonws}+", state="INITIAL")
void matchWord ()
{
m_cc += yyLength ();
++m_wc;
}
Specifying Lexical Patterns¶
@Lex
is use to specify a single lexical pattern. @Lexs
is used
to specify multiple lexical patterns that share a common action.
There are three types functions that can be marked with these two annotations. They each has different meanings.
None of the functions can be private
, since they are called from the
generated class. They can be protected
, public
or in the package
scope (if the generated class is in the same package as this class).
Case 1: Function returns void¶
This is the most simple case. The lexer would call this function and then move on to matching the next potential pattern. For example:
@Lex (pattern = "[ \\t\\r\\n]+")
protected void ignoreWhiteSpace ()
{
}
Note that it is necessary to use double backslashes here for escape
sequences because Java itself also interpret escape sequences. This is
perhaps one of the main drawback using Java annotation to specify the
lexer. Fortunately usually the lexer is fairly easy to get it working
correctly. IntelliJ IDEA also has a nice feature which pasting code with
escape sequence such as [ \t\r\n]+
inside a pair of double quotes
would automatically adds the extra backslashes.
Case 2: Function returns a non-int value¶
In this case, @Lex
needs to contain the terminal token that would be
returned. The return value from the function is going to be the value
associated with this terminal.
We have to specify the terminal in String due to the technical limitation.
@Lex (pattern="[0-9]+", token="INTEGER")
protected Integer parseInt ()
{
return Integer.parseInt (yyText ());
}
@Lexs (patterns = {
@Lex (pattern = "while", token = "WHILE"),
@Lex (pattern = "if", token = "IF"),
@Lex (pattern = "else", token = "ELSE"),
@Lex (pattern = "print", token = "PRINT")
})
protected Object parseKeyword ()
{
return null;
}
Case 3: Function returns an int value¶
In this case, the lexer would return the value. For example:
@Lex (pattern="[(){}.]")
protected int parseSymbol ()
{
return yyText ().charAt (0);
}
Be extra careful if the return value is used as terminals in the parser. Values not in the valid used terminals can result in the early termination of the parser.
Note that when <<EOF>>
is encountered, it is necessary to return a
value or the lexer would get into an infinite loop. There are a number
of ways of doing so:
@Lex (pattern = "<<EOF>>", token = "$")
protected void parseEOF ()
{
}
Or you can simply do
@Lex (pattern = "<<EOF>>")
protected int parseEOF ()
{
return 0;
}
This is because $
terminal corresponds to 0.
Parser Section¶
Specifying Parser Rules¶
@Rule
specifies a single grammar rule. @Rules
can be used to
specify multiple rules that share the same function action.
There are also three cases of functions marked using @Rule
Case 1: Function returns void¶
In this case, the value associated with the non-terminal of the LHS is null.
@Rule (lhs = "function", rhs = "function stmt", args = "2")
protected void parseFunction (Node node)
{
interpret (node);
}
Case 2: Function returns a non-int value¶
In this case, the return value is automatically associated with the non-terminal on the LHS.
@Rule (lhs = "stmt", rhs = "SEMICOLON")
protected Node parseStmt ()
{
return new SemiColonNode ();
}
Case 3: Function returns an int value¶
This function is used by the grammar start non-terminal to signal the exit of the parser with the particular value. It can be used by error processing functions as well.
@Rule (lhs = "program", rhs = "function")
protected int parseProgram ()
{
return 0;
}
Passing Arguments¶
args
of the @Rule
annotation is a list of indexes (separated by
comma or space) of the symbols which the method expects as arguments.
The indexing value starts from 1 for the production on the RHS.
For example:
@Rule (lhs = "stmt", rhs = "VARIABLE ASSIGN expr SEMICOLON", args = "1 3")
protected Node parseAssign (String var, Node expr)
{
return new AssignNode (var, expr);
}
This will assign the value of symbol VARIABLE
to the method
parameter String var
and the value of symbol expr
to the method
parameter Node expr
.
Note that the indexes need not be in any specific order. This would be equivalent (indexes and method parameters swapped):
@Rule (lhs = "stmt", rhs = "VARIABLE ASSIGN expr SEMICOLON", args = "3 1")
protected Node parseAssign (Node expr, String var)
{
return new AssignNode (var, expr);
}
As you can see, one does not have to mess with $$
, $1
etc, and
does not have to deal with type information specified elsewhere. This
approach is much more intuitive.
Examples¶
There are a number of examples in test cases.


Add hosts manually, or by uploading scan data.
You could also run auxilliary scan modules!
This has been very useful for my research. Thanks as well!

--- Day 25: Sea Cucumber ---
This is it: the bottom of the ocean trench, the last place the sleigh keys could be. Your submarine's experimental antenna still isn't boosted enough to detect the keys, but they must be here. All you need to do is reach the seafloor and find them.
At least, you'd touch down on the seafloor if you could; unfortunately, it's completely covered by two large herds of sea cucumbers, and there isn't an open space large enough for your submarine.
You suspect that the Elves must have done this before, because just then you discover the phone number of a deep-sea marine biologist on a handwritten note taped to the wall of the submarine's cockpit.
"Sea cucumbers? Yeah, they're probably hunting for food. But don't worry, they're predictable critters: they move in perfectly straight lines, only moving forward when there's space to do so. They're actually quite polite!"
You explain that you'd like to predict when you could land your submarine.
"Oh that's easy, they'll eventually pile up and leave enough space for-- wait, did you say submarine? And the only place with that many sea cucumbers would be at the very bottom of the Mariana--" You hang up the phone.
There are two herds of sea cucumbers sharing the same region; one always moves east (>
), while the other always moves south (v
). Each location can contain at most one sea cucumber; the remaining locations are empty (.
). The submarine helpfully generates a map of the situation (your puzzle input). For example:
v...>>.vv>
.vv>>.vv..
>>.>v>...v
>>v>>.>.v.
v>v.vv.v..
>.>>..v...
.vv..>.>v.
v.v..>>v.v
....v..v.>
Every step, the sea cucumbers in the east-facing herd attempt to move forward one location, then the sea cucumbers in the south-facing herd attempt to move forward one location. When a herd moves forward, every sea cucumber in the herd first simultaneously considers whether there is a sea cucumber in the adjacent location it's facing (even another sea cucumber facing the same direction), and then every sea cucumber facing an empty location simultaneously moves into that location.
So, in a situation like this:
...>>>>>...
After one step, only the rightmost sea cucumber would have moved:
...>>>>.>..
After the next step, two sea cucumbers move:
...>>>.>.>.
During a single step, the east-facing herd moves first, then the south-facing herd moves. So, given this situation:
..........
.>v....v..
.......>..
..........
After a single step, of the sea cucumbers on the left, only the south-facing sea cucumber has moved (as it wasn't out of the way in time for the east-facing cucumber on the left to move), but both sea cucumbers on the right have moved (as the east-facing sea cucumber moved out of the way of the south-facing sea cucumber):
..........
.>........
..v....v>.
..........
Due to strong water currents in the area, sea cucumbers that move off the right edge of the map appear on the left edge, and sea cucumbers that move off the bottom edge of the map appear on the top edge. Sea cucumbers always check whether their destination location is empty before moving, even if that destination is on the opposite side of the map:
Initial state:
...>...
.......
......>
v.....>
......>
.......
..vvv..
After 1 step:
..vv>..
.......
>......
v.....>
>......

....v..
After 2 steps:
....v>.
..vv...

..>v...
>......
..>....
v......
.......
After 4 steps:
>......
..v....
..>.v..
.>.v...
...>...
.......
v......
To find a safe place to land your submarine, the sea cucumbers need to stop moving. Again consider the first example:
Initial state:
v...>>.vv>
.vv>>.vv..
>>.>v>...v
>>v>>.>.v.
v>v.vv.v..

Closest Image to a Specific Date¶
Let’s see how to get the closest image (or set of images) to a specific date.
Before anything, let’s import our modules and authenticate in Google Earth Engine:
import ee, eemont
ee.Authenticate()
ee.Initialize()
Now, we are ready to go!
Overview¶
The eemont package extends the ee.ImageCollection class with the method closest()
:
|
Gets the closest image (or set of images if the collection intersects a region that requires multiple scenes) to the specified date. |
This method automatically filters any image collection to get the closest image to a specific date.
Warning
This method uses the system:time_start
property, therefore, make sure your image collection has it!
Usage¶
The closest()
method works on any image colection that has a system:time_start
property.
First, let’s take the Sentinel-2 image collection as example:
S2 = ee.ImageCollection('COPERNICUS/S2_SR')
Now, we have to filter the collection to our ROI. The result of the closest()
method will vary depending on this.
Let’s assume a single point is our ROI.
ROI = ee.Geometry.Point([-76.45, 4.32])
S2 = S2.filterBounds(ROI)
Now, the closest()
method has just one parameter, date
, and this parameter can be a string…
S2.closest('2020-10-15')
Or an ee.Date class:
dateOfInterest = ee.Date('2020-10-15')
S2.closest(dateOfInterest)
Both chunks will give you the same result here: an ee.ImageCollection of size 1. The result has just one image since our ROI intersects just one scene.
To get that image as a single image, we can use the first()
method.
S2.closest('2020-10-15').first()
By default, the image collection is filtered according to +/- 1 month from the date
parameter (tolerance = 1
and unit = 'month'
). This is done to speed up the searching process, but if required (if there are not images in that range), the tolerance
and unit
parameters can be modified:
S2.closest('2020-10-15', tolerance = 2, unit = 'year')
Now, let’s assume that our ROI is larger, in this case, a whole department (state) of Colombia:
ROI = (ee.FeatureCollection('FAO/GAUL_SIMPLIFIED_500m/2015/level1')
.filter(ee.Filter.eq('ADM1_NAME','Valle Del Cauca')))
S2 = ee.ImageCollection('COPERNICUS/S2_SR').filterBounds(ROI).closest('2020-10-15')
You’ll note that the size of the resulting ee.ImageCollection here is greater than 1. This result has more than one image since our ROI now intersects more than one scene.
To get those images together as a single image, you can mosaic them or use an ee.Reducer, for example median()
.
S2.median()


Rogue is a visual CRT based fantasy game which runs under the UNIX† timesharing system. This paper describes how to play rogue, and gives a few hints for those who might otherwise get lost in the Dungeons of Doom.
You have just finished your years as a student at the local fighter’s guild. After much practice and sweat you have finally completed your training and are ready to embark upon a perilous adventure. As a test of your skills, the local guildmasters have sent you into the Dungeons of Doom. Your task is to return with the Amulet of Yendor. Your reward for the completion of this task will be a full membership in the local guild. In addition, you are allowed to keep all the loot you bring back from the dungeons.
In preparation for your journey, you are given an enchanted mace, a bow, and a quiver of arrows taken from a dragon’s hoard in the far off Dark Mountains. You are also outfitted with elf-crafted armor and given enough food to reach the dungeons.
You set out on your way to the dungeons and after several days of uneventful travel, you see the ancient ruins that mark the entrance to the Dungeons of Doom. It is late at night, so you make camp at the entrance and spend the night sleeping under the open skies.
You have just begun a game of rogue. Your goal is to grab as much treasure as you can, find the Amulet of Yendor, and get out of the Dungeons of Doom alive. On the screen, a map of where you have been and what you have seen on the current dungeon level is kept. As you explore more of the level, it appears on the screen in front of you.
Rogue differs from most computer fantasy games in that it is screen oriented. Commands are all one or two keystrokes1 and the results of your commands are displayed graphically on the screen rather than being explained in words2.
Another major difference between rogue and other computer fantasy games is that once you have solved all the puzzles in a standard fantasy game, it has lost most of its excitement and it ceases to be fun. Rogue, on the other hand, generates a new dungeon every time you play it and even the author finds it an entertaining and exciting game.
In order to understand what is going on in rogue you have to first get some grasp of what rogue is doing with the screen. The rogue screen is intended to replace the “You can see ...” descriptions of standard fantasy games. Figure 1 is a sample of what a rogue screen might look like.
____________________________________________________________ ------------ |..........+<EMAIL_ADDRESS>|....B.....| |..........| -----+------ Level: 1 Gold: 0 Hp: 12(12) Str: 16(16) Arm: 4 Exp: 1/0 Figure 1 ____________________________________________________________ |
At the bottom line of the screen are a few
pieces of cryptic information describing your current
status. Here is an explanation of what these things
mean:
|
Level |
This number indicates how deep you have gone in the dungeon. It starts at one and goes up as you go deeper into the dungeon. |
|
Gold |
The number of gold pieces you have managed to find and keep with you so far. |
|
Hp |
Your current and maximum health points. Health points indicate how much damage you can take before you die. The more you get hit in a fight, the lower they get. You can regain health points by resting. The number in parentheses is the maximum number your health points can reach. |
|
Str |
Your current strength and maximum ever strength. This can be any integer less than or equal to 31, or greater than or equal to three. The higher the num- ber, the stronger you are. The number in the parentheses is the maximum strength you have attained so far this game. |
|
Arm |
Your current armor protection. This number indicates how effective your armor is in stopping blows from unfriendly creatures. The higher this number is, the more effective the armor. |
|
Exp |
These two numbers give your current experience level and experience points. As you do things, you gain experience points. At certain experience point totals, you gain an experience level. The more experienced you are, the better you are able to fight and to withstand magical attacks. |
The top line of the screen is reserved for printing messages that describe things that are impossible to represent visually. If you see a “--More--” on the top line, this means that rogue wants to print another message on the screen, but it wants to make certain that you have read the one that is there first. To read the next message, just type a space.
The rest of the screen is the map of the level as you have explored it so far. Each symbol on the screen repre- sents something. Here is a list of what the various symbols mean:
|
@ |
This symbol represents you, the adventurer. |
|
- | |
These symbols represent the walls of rooms. |
|
+ |
A door to/from a room. |
|
. |
The floor of a room. |
|
# |
The floor of a passage between rooms. |
|
* |
A pile or pot of gold. |
|

A weapon of some sort. |
|

The uppercase letters represent the various inhabitants of the Dungeons of Doom. Watch out, they can be nasty and vicious. |
Commands are given to rogue by typing one or two characters.
Most commands can be preceded by a count to repeat them (e.g. typing “10s” will
do ten searches). Commands for which counts make no sense have the count
ignored. To cancel a count or a prefix, type <ESCAPE> . The list of commands is
rather long, but it can be read at any time during the game
with the “?” command. Here it is for reference,
with a short explanation of each
command.
|
? |
The help command. Asks for a character to give help on. If you type a “*”, it will list all the commands, otherwise it will explain what the character you typed does. |
|
/ |
This is the “What is that on the screen?” command. A “/” followed by any character that you see on the level, will tell you what that character is. For instance, typing “/@” will tell you that the “@” symbol represents you, the player. |
|
h, H, ^H |
|
|
Move left. You move one space to the left. If you use upper case “h”, you will continue to move left until you run into something. This works for all movement commands (e.g. “L” means run in direction “l”) If you use the “control” “h”, you will continue moving in the specified direction until you pass something interesting or run into a wall. You should experiment with this, since it is a very useful command, but very difficult to describe. This also works for all movement commands. |
|
|
j |
Move down. |
|
k |
Move up. |
|
l |
Move right. |
|
y |
Move diagonally up and left. |
|
u |
Move diagonally up and right. |
|
b |
Move diagonally down and left. |
|
n |
Move diagonally down and right. |
|
t |
Throw an object. This is a prefix command. When followed with a direction it throws an object in the specified direction. (e.g. type “th” to throw something to the left.) |
|
f |
Fight until someone dies. When followed with a direction this will force you to fight the creature in that direction until either you or it bites the big one. |
|
m |
Move onto something without picking it up. This will move you one space in the direction you specify and, if there is an object there you can pick up, it won’t do it. |
|
z |
Zap prefix. Point a staff or wand in a given direction and fire it. Even non-directional staves must be pointed in some direction to be used. |
|
^ |
Identify trap command. If a trap is on your map and you can’t remember what type it is, you can get rogue to remind you by getting next to it and typing “^” followed by the direction that would move you on top of it. |
|
s |
Search for traps and secret doors. Examine each space immediately adjacent to you for the existence of a trap or secret door. There is a large chance that even if there is something there, you won’t find it, so you might have to search a while before you find something. |
|
> |
Climb down a staircase to the next level. Not surprisingly, this can only be done if you are standing on staircase. |
|
< |
Climb up a staircase to the level above. This can’t be done without the Amulet of Yendor in your possession. |
|
. |
Rest. This is the “do nothing” command. This is good for waiting and healing. |
|
, |
Pick up something.  List what you are carrying in your pack. |
|
I |
Selective inventory. Tells you what a single item in your pack is. |
|
q |
Quaff one of the potions you are carrying. |
|
r |
Read one of the scrolls in your pack. |
|
e |
Eat food from your pack. |
|
w |
Wield a weapon. Take a weapon out of your pack and carry it for use in combat, replacing the one you are currently using (if any). |
|
W |
Wear armor. You can only wear one suit of armor at a time. This takes extra time. |
|
T |
Take armor off. You can’t remove armor that is cursed. This takes extra time. |
|
P |
Put on a ring. You can wear only two rings at a time (one on each hand). If you aren’t wearing any rings, this command will ask you which hand you want to wear it on, otherwise, it will place it on the unused hand. The program assumes that you wield your sword in your right hand. |
|
R |
Remove a ring. If you are only wearing one ring, this command takes it off. If you are wearing two, it will ask you which one you wish to remove, |
|
d |
Drop an object. Take something out of your pack and leave it lying on the floor. Only one object can occupy each space. You cannot drop a cursed object at all if you are wielding or wearing it. |
|
c |
Call an object something. If you have a type of object in your pack which you wish to remember something about, you can use the call command to give a name to that type of object. This is usually used when you figure out what a potion, scroll, ring, or staff is after you pick it up, or when you want to remember which of those swords in your pack you were wielding. |
|
D |
Print out which things you’ve discovered something about. This command will ask you what type of thing you are interested in. If you type the character for a given type of object (e.g. “!” for potion) it will tell you which kinds of that type of object you’ve discovered (i.e., figured out what they are). This command works for potions, scrolls, rings, and staves and wands. |
|
o |
Examine and set options. This command is further explained in the section on options. |
|
^R |
Redraws the screen. Useful if spurious messages or transmission errors have messed up the display. |
|
^P |
Print last message. Useful when a message disappears before you can read it. This only repeats the last message that was not a mistyped command so that you don’t loose anything by accidentally typing the wrong character instead of ^P. |
|
<ESCAPE> |
|
| Cancel a command, prefix, or count. | |
|
! |
Escape to a shell for some commands. |
|
Q |
Quit. Leave the game. |
|
S |
Save the current game in a file. It will ask you whether you wish to use the default save file. Caveat: Rogue won’t let you start up a copy of a saved game, and it removes the save file as soon as you start up a restored game. This is to prevent people from saving a game just before a dangerous position and then restart- ing it if they die. To restore a saved game, give the file name as an argument to rogue. As in % rogue save_file To restart from the default save file (see below), run % rogue -r |

Rooms in the dungeons are either lit or dark. If you walk into a lit room, the entire room will be drawn on the screen as soon as you enter. If you walk into a dark room, it will only be displayed as you explore it. Upon leaving a room, all monsters inside the room are erased from the screen. In the darkness you can only see one space in all directions around you. A corridor is always dark.
If you see a monster and you wish to fight it, just attempt to run into it. Many times a monster you find will mind its own business unless you attack it. It is often the case that discretion is the better part of valor.
When you find something in the dungeon, it is common to want to pick the object up. This is accomplished in rogue by walking over the object (unless you use the “m” prefix, see above). If you are carrying too many things, the pro- gram will tell you and it won’t pick up the object, other- wise it will add it to your pack and tell you what you just picked up.
Many of the commands that operate on objects must prompt you to find out which object you want to use. If you change your mind and don’t want to do that command after all, just type an <ESCAPE> and the command will be aborted.
Some objects, like armor and weapons, are easily dif- ferentiated. Others, like scrolls and potions, are given labels which vary according to type. During a game, any two of the same kind of object with the same label are the same type. However, the labels will vary from game to game.
When you use one of these labeled objects, if its effect is obvious, rogue will remember what it is for you. If it’s effect isn’t extremely obvious you will be asked what you want to scribble on it so you will recognize it later, or you can use the “call” command (see above).
Some weapons, like arrows, come in bunches, but most come one at a time. In order to use a weapon, you must wield it. To fire an arrow out of a bow, you must first wield the bow, then throw the arrow. You can only wield one weapon at a time, but you can’t change weapons if the one you are currently wielding is cursed. The commands to use weapons are “w” (wield) and “t” (throw).
There are various sorts of armor lying around in the dungeon. Some of it is enchanted, some is cursed, and some is just normal. Different armor types have different armor protection. The higher the armor protection, the more protection the armor affords against the blows of monsters. Here is a list of the various armor types and their normal armor protection:
| Type | Protection |
|---|---|
| None | 0 |
| Leather armor | 2 |
| Studded leather / Ring mail | 3 |
| Scale mail | 4 |
| Chain mail | 5 |
| Banded mail / Splint mail | 6 |
| Plate mail | 7 |
If a piece of armor is enchanted, its armor protection will be higher than normal. If a suit of armor is cursed, its armor protection will be lower, and you will not be able to remove it. However, not all armor with a protection that is lower than normal is cursed.
The commands to use weapons are “W” (wear) and “T” (take off).
Scrolls come with titles in an unknown tongue3. After you read a scroll, it disappears from your pack. The com mand to use a scroll is “r” (read).
Potions are labeled by the color of the liquid inside the flask. They disappear after being quaffed. The command to use a scroll is “q” (quaff).
Staves and wands do the same kinds of things. Staves are identified by a type of wood; wands by a type of metal or bone. They are generally things you want to do to some- thing over a long distance, so you must point them at what you wish to affect to use them. Some staves are not affected by the direction they are pointed, though. Staves come with multiple magic charges, the number being random, and when they are used up, the staff is just a piece of wood or metal.
The command to use a wand or staff is “z” (zap)
Rings are very useful items, since they are relatively permanent magic, unlike the usually fleeting effects of potions, scrolls, and staves. Of course, the bad rings are also more powerful. Most rings also cause you to use up food more rapidly, the rate varying with the type of ring. Rings are differentiated by their stone settings. The com- mands to use rings are “P” (put on) and “R” (remove).
Food is necessary to keep you going. If you go too long without eating you will faint, and eventually die of starvation. The command to use food is “e” (eat).
Due to variations in personal tastes and conceptions of the way rogue should do things, there are a set of options you can set that cause rogue to behave in various different ways.
There are two ways to set the options. The first is with the “o” command of rogue; the second is with the “ROGUEOPTS” environment variable.
When you type “o” in rogue, it clears the screen and displays the current settings for all the options. It then places the cursor by the value of the first option and waits for you to type. You can type a <RETURN> which means to go to the next option, a “−” which means to go to the previous option, an <ESCAPE> which means to return to the game, or you can give the option a value. For boolean options this merely involves typing “t” for true or “f” for false. For string options, type the new value followed by a <RETURN> .
The ROGUEOPTS variable is a string containing a comma separated list of initial values for the various options.  Thus to set up an environment variable so that jump is on, terse is off, and the name is set to “Blue Meanie”, use the command
% setenv ROGUEOPTS "jump,noterse,name=Blue Meanie"4
Here is a list of the options and an explanation of what each one is for. The default value for each is enclosed in square brackets. For character string options, input over fifty characters will be ignored.
terse [noterse]
Useful for those who are tired of the sometimes lengthy messages of rogue. This is a useful option for playing on slow terminals, so this option defaults to terse if you are on a slow (1200 baud or under) terminal.
jump [nojump]
If this option is set, running moves will not be displayed until you reach the end of the move. This saves considerable cpu and display time. This option defaults to jump if you are using a slow terminal.
flush [noflush]
All typeahead is thrown away after each round of battle. This is useful for those who type far ahead and then watch in dismay as a Bat kills them.
seefloor [seefloor]
Display the floor around you on the screen as you move through dark rooms. Due to the amount of characters generated, this option defaults to noseefloor if you are using a slow terminal.
passgo [nopassgo]
Follow turnings in passageways. If you run in a pas- sage and you run into stone or a wall, rogue will see if it can turn to the right or left. If it can only turn one way, it will turn that way. If it can turn either or neither, it will stop. This algorithm can sometimes lead to slightly confusing occurrences which is why it defaults to nopassgo.
tombstone [tombstone]
Print out the tombstone at the end if you get killed. This is nice but slow, so you can turn it off if you like.
inven [overwrite]
Inventory type. This can have one of three values: overwrite, slow, or clear. With overwrite the top lines of the map are overwritten with the list when inventory is requested or when “Which item do you wish to . . .? ” questions are answered with a “*”. How- ever, if the list is longer than a screenful, the screen is cleared. With slow, lists are displayed one item at a time on the top of the screen, and with clear, the screen is cleared, the list is displayed, and then the dungeon level is re-displayed. Due to speed considerations, clear is the default for terminals without clear-to-end-of-line capabilities.
name [account name]
This is the name of your character. It is used if you get on the top ten scorer’s list.
fruit [slime-mold]
This should hold the name of a fruit that you enjoy eating. It is basically a whimsy that rogue uses in a couple of places.
file [~/rogue.save]
The default file name for saving the game. If your phone is hung up by accident, rogue will automatically save the game in this file. The file name may start with the special character “~” which expands to be your home directory.
Rogue usually maintains a list of the top scoring people or scores on your machine. Depending on how it is set up, it can post either the top scores or the top players. In the latter case, each account on the machine can post only one non-winning score on this list. If you score higher than someone else on this list, or better your previous score on the list, you will be inserted in the proper place under your current name. How many scores are kept can also be set up by whoever installs it on your machine.
 If, however, you get killed in the Dungeons of Doom, your body is forwarded to your next-of-kin, along with 90% of your gold; ten percent of your gold is kept by the Dungeons’ wizard as a fee5. This should make you consider whether you want to take one last hit at that monster and possibly live, or quit and thus stop with whatever you have. If you quit, you do get all your gold, but if you swing and live, you might find more.
If you just want to see what the current top players/games list is, you can type
% rogue −s
Rogue was originally conceived of by Glenn Wichman and Michael Toy. Ken Arnold and Michael Toy then smoothed out the user interface, and added jillions of new features. We would like to thank Bob Arnold, Michelle Busch, Andy Hatcher, Kipp Hickman, Mark Horton, Daniel Jensen, Bill Joy, Joe Kalash, Steve Maurer, Marty McNary, Jan Miller, and Scott Nelson for their ideas and assistance; and also the teeming multitudes who graciously ignored work, school, and social life to play rogue and send us bugs, complaints, suggestions, and just plain flames.

Support for testing time-consuming tasks.
A good example is the main window of an application beign shown after the user's credentials have been successfully verified. The following are the typical steps to complete such scenario:
The "tricky" part here is step 4. Authentication/authorization can take some time (depending on network traffic, etc.) and we need to wait for the main window to appear in order to continue our test. It is possible to test this scenario with FEST:
loginDialog.textBox("username").enterText("yvonne"); loginDialog.textBox("password").enterText("welcome"); loginDialog.button("login").click(); // now the interesting part, we need to wait till the main window is shown. FrameFixture mainFrame = findFrame("main").using(loginDialog.robot); // we can continue testing the main window.
The "{@link org.fest.swing.finder.WindowFinder#findFrame(String) findFrame}
" method
(statically imported from {@link org.fest.swing.finder.WindowFinder}
) can lookup a Frame
(having "main" as its name) with a default timeout of 5 seconds. That means that if in 5 seconds the
frame we are looking for is not found, the test will fail.
We can also specify a custom value for the timeout. For example, we can set the timeout to 10 seconds in two ways:
FrameFixture mainFrame = findFrame("main").withTimeout(10000).using(loginDialog.robot); // or FrameFixture mainFrame = findFrame("main").withTimeout(10, SECONDS).using(loginDialog.robot);
We can also look up Frames by type:
FrameFixture mainFrame = findFrame(MainFrame.class).using(loginDialog.robot);
Something that you may find weird in the code examples is "using(loginDialog.robot)
."
This is necessary because, in a given test, only one instance of
{@link org.fest.swing.core.Robot Robot}
can be
running, to prevent GUI tests from blocking each other on the screen. In another words, in a test class you can
only use one and only one instance of Robot
.


Man behind Lord Buckethead in 2017 election to run in PM’s constituency
Writer Jon Harvey will return, but this time as Count Binface.
The human behind Lord Buckethead’s 2017 election campaign against Theresa May is set to run in Boris Johnson’s constituency under a new alias.
Jon Harvey will stand in the Prime Minister’s constituency of Uxbridge and South Ruislip as Count Binface, citing “an unpleasant battle on the planet Copyright” as the reason for his regeneration.
Mr Harvey won 249 votes in May’s constituency two-and-a-half years ago as Lord Buckethead, a character from Gremloids, a 1984 film, but reportedly gave up the role after discussions with the film’s creator.
Count Binface – described in a statement as “independent space warrior and prospective parliamentary candidate for Uxbridge and South Ruislip” and “Leader of the Recyclons” – will campaign to bring back Ceefax, as well as fighting for “a cleaner, greener galaxy”.
Addressing his return, Count Binface added “I predicted that Brexit would be a s***show and so it proved.”
And while Count Binface’s attention will no doubt be fixed in part on the Prime Minister, a more personal battle could be on the horizon with another Lord Buckethead running in the same constituency, this time for The Official Monster Raving Loony Party.
“I look forward to both the hustings and to challenging the new ‘Lord Buckethead’ to take part in a Receptacle-to-Receptacle debate,” Count Binface said.

Version Control & Getting Started
Friday April 10th 2015
The first question to ask yourself is, What is version control? Version control is a collection of files for any project that are gathered over time. The files are ones that have been changed to update the project that is being worked on. The version control allows a user to swap to an earlier version of a project in case there is an error with the code or if the path that was chosen needed a change. This system also allows multiple users to access the project and make changes as they see fit.
Git is a type of version control. Any changes to a project are only made locally on one's computer. Git keeps track of all changes with dates that are made. Once a change is made it needs to be added to the log. $Git add
As mentioned earlier Github is a site in which developers/programmers are able to share their code and projects. A benefit to Github is that a user can put a license on a project to protect permissions a person would have in using and distributing their code. It would be important to decide which type of license to use depending on the project one is working on. This certainly protects the original creator in any case. Having your code posted on an open source site really allows for different points of view and opinions to be added your code. Any issues a developer may have can be seen and helped on by any amount of people. Posting your code on an open source site really allows for project growth and great collaboration globally between anyone looking to make a change.

Nigerian man shares proof of verbal abuse he suffers from his sister
- A Nigerian man has taken to social media to share proof of the verbal abuse he suffers from his sister
- The man identified as Victor O Cheedoh shared some abusive messages his sister constantly sends to him
- In his Facebook post, he revealed he has been going through the abuse for a decade
While most of the spotlight is shone on cases of domestic violence, abusive relationships continue to take on different forms that more often than not, leave the victims broken.
A Nigerian man identified as Victor O Cheedoh recently left many people shocked after he took to the Facebook platform to reveal how his own sister constantly abuses him verbally. He shared screenshots of text messages from her in which she constantly insults him.
 Apparently all I do is sleep, smoke and drink to stupor. Oh and I’m a disappointment as well. To cut the long tale short.
PAY ATTENTION: Personal letter from the Editor-in-Chief of Legit.ng (former NAIJ.com)
"You’d be pretty shocked who sent this. This is a basic case of verbal abuse in the Nigerian home. I’ve decided to put an end to it and share with the world what I’ve been going through for about a decade now. I mean I guess I deserve it. Share your thoughts after the cut."

Meanwhile, while many parents have their children's interest at heart before many other things and will go to any lengths to protect them, it appears there are some who have a rather unorthodox way of showing it.
Such is reflected in the story of a lady who left her abusive husband but paid dearly for it with the help of her own mother. Twitter user @Mz_Tosyn shared the story on the platform. According to her, the mother found the daughter and got her beaten by the said abusive husband and eventually had her arrested.

As the standard for Imperial Documentation, the history of the Hagurin Characters deserves mention in this volume. While the number of original languages taken by the colonists from Terra is a matter for debate among scholars (estimates range from as few as 3 and as many as 100), the number of (distinct) languages in the Imperium is commonly noted at over 500.
Early in the Imperium’s development, in fact even during the formation of the Terran Republic, scholars and politicians like Benita Perez and Janoos Welkred were desperately searching for a reliable universal translation mechanism. This Test was finally passed by the scholar and mathematician Yamata Hagurai. Hagurai formulated a system of characters to represent all the concepts, themes, and grammatic logic in the languages he knew. Additionally, he embedded a subset of phonetic characters to be combined for the specific pronounciation of names and unique cultural concepts. Perhaps most inspired, he designed the characters to be easily read by machine. Hagurai’s original set has only been modified slightly since then to include 4 new phoenetic characters and almost 400 conceptual ones.
While some have called the set an artificial language, this scholar does not accept this diagnosis. Primarily because the language is not “spoken” by anyone, and it does not appear to develop as a language would. The conceptual characters do not have any specified pronounciation, since they are interpreted in whatever native language the reader chooses.
While originally only used by a specialized class of scribes and the Librarian Society, software was quickly developed to help translate writing into Hagurin. In most languages, the software still requires writer-prompting for clarification purposes, linguists say this is unavoidable, as natural languages are often confusing that way. Reverse translation into another language is often stilted and rather “robotic.” However, it does faithfully translate the meaning, if not necessarily the flavor of the original work. In addition, frequent travellers will recognize the symbols for such things as “restaurant”, “restroom”, “water”, and “communication station”.
By the time of the Grand Reforms, many people have learned to read the characters as the primary method of manual writing, and information dispersal. Handwriting in the character set is next to impossible, and only practiced as a meditative discpline on worlds with that cultural tradition. Many scholars have

FINE ENERGY
Like an FAQ, many questions that are likely to be
asked upon using this website and its data
What is the electrical appliance that consumes the most energy on average?
From the pie chart it can be seen that the data is inclined towards the "other" category building up of over fifty percent of the pie chart. From the chart we can also see that seasonal appliances that are running continuously are a large contributor to high energy consumption rates.
Assuming that the "other" category represents electricity usage sourcing from lighting, appliances and television, we can conclude that heating and cooling are not a main contributor to high energy consumption rates.
This is quantitative evidence proving that the main contributor to high energy consumption rates is due to appliances left on draining energy from standby mode and other continuous cycles such as lighting and heating/cooling in the appropriate season.
Fig 1: Average Percentage of Energy Consumption per Appliance
Do cites with denser populations consume more energy than less dense areas by KWH per person?
From the graph under the Visualisations tab or through the table button below, we can conclude that not necessarily denser states will consume more energy.
By finding the average useage of the each person in every selection zone, namely state group, divison or region, this eliminates the discrepancies across areas. Therefore, a proportionate standing can be evaluated across all areas.
By doing so, the results show that state groups generally do have a linear relationship when it comes to measuring their energy usage per person and the relative size of the zone. This is further consolidated by the fact that in these zones, there is often regular seasonal fluctuations hence heating and cooling usage is expected to be high. On the other hand the outlier, the state of California, resulted in a low energy per person rate despite its large population. It is suspected that the state has more mild weather, and is technologically advanced with energy-saving options, that the energy consumption level is relatively low.
How much is it per person to live in that particular area? Is it worth it?
From the graph under the Visualisations tab or through the table button below, our findings conclude that the "best place to be" would be a place with a reasonable cost per person and low energy consumption per person.
By correlating the data between the average energy consumption per person in each area and the total cost of the whole area, it can be found that places with a higher energy usage per person tend to be places with varying weather. This prompts the consumption of more energy such as heating, cooling and lighting.
Hence, areas with lower energy usage per person, have a constant weather pattern which is ideal for residing in. Whether or not it is "worth it" is dependant on the individual, namely if living at the expense of higher costs in a better area is ideal.
Since we know which appliance consumes the most power. Then which one will end up costing the most money?
Refering back to Fig 1 and the graph under Visualisations, it can be concluded that the appliance that will end up costing the most money will be the one with the highest consumption
The reasoning is that it is assumed that the cost of using an electrical appliance is linearly proportionate to the cost of the energy consumed. The graph highlights this under its total area for each appliance.
Is there a correlation between number of occupants in a residence and the total energy consumption?
There is a positive correlation between the number of occupants against the total energy consumption levels.
From the pivot table provided, there shows a positive correlation between these two variables in the dataset. This indicates that the more people in the house there are, the more energy is consumed through daily activites and necessities.


This project aims to show how reactive Akka Streams could provide an appealing way of working with RabbitMQ.
We are assuming some basic knowledge of RabbitMQ. Otherwise you wouldn't probably be here. But if this is one of these rare cases then please look closer at this cool piece of technology here http://www.rabbitmq.com/ .
You should have a RabbitMQ server installed locally with a management plug-in.
This application simulates a simplified censorship (yes, censorship) procedure, that intercepts private messages, makes a content analysis, and qualifies the message as OK or NOT OK. So the scenario is as follows:
Queue --> Akka Stream --> Exchange
After running the application, go to the RabbitMQ management console at http://localhost:15672/ , find an exchange named censorship.inbound.exchange and start publishing messages.
You should observe two effects:
You will notice that messages containing the word 'terror' will go to the nok queue. This is the initial censorship filter. Feel free to modify the "forbidden words" list.
Below you will find main steps for this whole process.
RabbitConsumerActor is responsible for initializing a channel to the queue and registering
a consumer for that queue. It will then serve as a stream Producer
, by calling onNext
whenever a new message comes from the server and the stream is ready to process it. Otherwise the message will be rejected and requeued on RabbitMQ.
To split the work into logical parts we are using Duct[In, Out]
. This allows us to define some message processing independently from the Flow
and connect the two later.
RabbitPublisher is responsible for initializing an outgoing channel.
It also creates a Duct
containing the logic for publishing a message back to a RabbitMQ exchange.
After receiving a connection from RabbitConnectionActor we combine these functions and call consume()
on the final flow. Simplified code would look something like this:
(Flow(rabbitConsumer) append domainProcessingDuct append publisherDuct).consume(materializer)
You just saw a clean functional way of working with RabbitMQ. There are of course many issues that haven't been addressed here, like the RabbitMQ Quality of Service property or rejecting messages at later stages of processing (to name a few). Also this is just a simple wrapper over the official RabbitMQ client, not a complete solution. But this should get you going and hopefully this is the way we'll be doing things in the future.

Joy Behar’s advice for 2020 Dems on guns: ‘Wait until you
by Douglas ErnstJoy Behar has some advice for Democrats who are running for president: Even if you want to confiscate guns from civilians, don’t tell voters that in advance.
The ladies of ABC’s “The View” conducted an autopsy of former Texas Rep. Beto O’Rourke’s presidential campaign on Monday when his plan to take guns from law-abiding citizens came up.
“They should not tell everything they’re going to do,” Ms. Behar said of the Texan’s now-famous “hell yes” attitude toward gun confiscation in America.
“If you are going to take people’s guns away, wait until you get elected and then take them away,” Ms. Behar said to laughs and clapping from the studio audience. “Don’t tell them ahead of time.”
Co-host Meghan McCain, a guns rights supporter, welcomed Ms. Behar’s commentary.
“By the way, that’s what people like me think you’re going to do,” she said. “I appreciate [Beto O’Rourke’s] honesty.”
Mr. O’Rourke ended his campaign on Friday while simultaneously vowing to fight the nation’s “epidemic of gun violence.”

Getting started with gruntjs
Referencing Article
Up and Running with GruntJS
GruntJS Primer
Built on top of Node.js, Grunt is a task-based command-line tool that speeds up workflows by reducing the effort required to prepare assets for production.
It does this by wrapping up jobs into tasks that are compiled automatically as you go along. Basically, you can use Grunt on most tasks that you consider to be grunt work and would normally have to manually configure and run yourself.
Simply put - it helps when you’re doing commands like
$ sass --watch main.sass:main.css
or
$ coffee --compile --watch main.coffee:main.js
or even
$ python -h SimpleHTTPServer
However, depending on your Gruntfile, you could just
$ grunt server
Ok Let’s get started…  Ok one of the MOST FRUSTRATING thing you should be aware about is if you have previously had node/npm install, you may need to use the command in your terminal.
$ sudo npm cache clean
Why?
Well, apparently, if you don’t clean/clear your cache, some dependancies will give you some errors like
npm ERR! cb() never called!
npm ERR! not ok code 0
I ended up using the yeoman generator, which I will outline below after I’ve worked tried Yeoman with Angular.
if you are using terminal and keep having the password prompting then the following seems to help
$ sudo chown -R `whoami` ~/.npm
$ sudo chown -R `whoami` /usr/local/lib/node_modules
There’s another command, which I will update at a later date which also seems to the same thing.
Update - Here is the terminal command to allow global installation via npm
$ sudo chown -R $USER /usr/local
I got pretty fed up with trying to generate a stand alone grunt project and ended up with using yeoman - which is further detailed in the following post
