To illustrate features of Cminor language in a somewhat more realistic context, we go through creating a desk calculator in this chapter.
Error handling in Cminor programs is best implemented using exceptions, because exceptions separate concerns of detecting an error condition and handling it using close to minimal code devoted to error handling.
For example, in the following main function, there are two nested try blocks, where the inner block handles known errors caused by incomplete or otherwise invalid input – ParsingException, trying to divide by zero – DivisionByZeroException, referring to a nonexisting variable – VariableNotFoundException, or trying to parse badly formatted string to a number – System.ConversionException. These user errors are handled by printing just the error message represented by the Message property of System.Exception class.
The outer try block handles all remaining errors, or errors that "should not happen". The System.Exception.ToString() method prints the call stack along with the error message, so that exact source code position of the error can be found.
The main loop consists of reading a line of input from the console, parsing and processing it, and also handling errorneous input. Then next line of input is read and processed, and so on, until user enters EOF followed by an ENTER to end the loop.
Here are the exception classes for various error conditions. In Cminor as in C# all exception classes must be derived from the System.Exception class. By catching System.Exception class all exceptions can be handled.
Unlike C#, Cminor contains nonmember functions, also called "free functions". They are functionally equivalent to static member functions in C#. Nonmember functions can be used to implement program logic that does not naturally belong to any class. Also operator functions operator+, operator-, operator*, and so on, are required to be nonmember functions in Cminor.
The following code creates an object of a Scanner class that is used to break up the input into tokens and also to skip any whitespace in input. Then the first token is read. If it is a PrintToken the current contents of variables are printed. Otherwise if it is a variable name token, and the next token is '=', an expression is parsed and its value is assigned to a variable. Otherwise the input is rewound and an expression is parsed and its value is printed:
An expression of the form "x is C", tests if the class of expression x is equal to class C,
or derived from it. If that is the case the value of expression "x is C" is true,
otherwise it's false. The language implementation of is-expression in Cminor does not need to crawl the class hierarchy,
because in intermediate code link time, each class is assigned an identifier of type ulong that is a product of prime factors.
The is test is reduced to an integer divisibility test:
"(id of class of x) % (id of class C) == 0".
This scheme is invented by Michael Gibbs and Bjarne Stroustrup and described in the article Fast Dynamic Casting
authored by them. The implementation of this scheme in Cminor is simpler than implementation for C++ described in the article because Cminor lacks multiple inheritance.
As already mentioned Cminor lacks multiple inheritance, but it allows a class to implement any number of interfaces. However in this simple program interfaces are not used. Here are the various token classes. The Token class is abstract meaning an object of it cannot be created. A class that contains abstract member functions, must also be declared abstract.
In Cminor a class may have properties that can be read-only – having a getter, write-only – having a setter, or read-write – having both getter and a setter. In the code above classes NumberToken, VariableNameToken and OperatorToken have read-only properties. Unlike in C#, properties in Cminor cannot be polymorphic – virtual, abstract or overridden. Properties can be static in Cminor, however. Static properties are accessed using ClassName.PropertyName notation.
Like in C#, values of basic value types are automatically boxed when needed, meaning an object containing a value of a basic value type is created. For example, statement object x = 1; creates an object of BoxedInt8 class and places an sbyte value 1 into that object. The reverse operation of unboxing converts an object of boxed value type back to an instance of basic value type. Unboxing must be performed explicitly by using a cast. For example, sbyte y = cast<sbyte>(x);. If the type of x is not BoxedInt8, an exception of class System.InvalidCastException is thrown. The Cminor system library source file BoxedTypes.cminor contains the boxed types and their operations. Explicit type conversion, casting is performed using syntax cast<sbyte>(x), not using the C# syntax (sbyte)x, because this way casts can be found from source code with search tools using regular expressions.
Cminor contains minimal support for Unicode, not perfect, but usable at least in western Europe countries where the author is from. The support is implemented as static member functions of the System.BoxedChar class. For example, char.IsLetter(x) returns true if character x has Unicode letter character category. The following Scanner class illustrates using character classification functions char.IsLetter(char) and char.IsNumber(char) and also parsing a double to a string – double.Parse(string):
Cminor system library has the following generic collections implemented as templates:
The calculator stores the values of variables in a System.Collections.Generic.Map<string, double> by mapping the name of the variable to the value of the variable. If the key of an element is not already found in the map, the subscripting operator of the map inserts the element to the map. Otherwise, if the key is already found in the map, the new value replaces the old value.
Each collection class implements an interface called Enumerable. An Enumerable class has a member function called GetEnumerator() that returns an object of a class that in turn implements an interface called Enumerator. The Enumerator interface differs from the C# language interface of the same name by providing a simplified functionality. The Cminor Enumerator interface has three functions instead of two:
The Print() member function of the SymbolTable class above uses enumerator interface implicitly to enumerate all the variables in the map, because the foreach statement is implemented in terms of Enumerable and Enumerator interfaces: statement foreach (Type x in collection) { statement; } is lowered by the compiler to the following code:
A parser can be implemented by hand as functions that call each other possibly recursively. This kind of parser is called a recursive-descent parser. The syntax of arithmetic expressions we are parsing is as follows:
We will write each production as a nonmember function that returns the value of the parsed subexpression. Here's the Expr() function that corresponds to the <expr> production. It parses <term>s separated by '+' and '-' characters:
The expression "x as C" is functionally equavalent to the similar C# language construct: If class of x is class C or derived from C the result of the as expression is x converted to C, otherwise it is null. The class-of test is implemented using similar integer divisibility expression in terms of class identifiers as for the is-expression.
Here's the Term() function that corresponds to the <term> production. It parses <factors>s separated by '*' and '/' characters:
The <factor> production is implemented by the following Factor() function. It parses <primaries> prefixed by '+' and '-' signs:
Here comes finally the implementation of the <primary> production. It parses numbers, variable names and subexpressions:
When the primary starts with the left parenthesis the Primary function calls the Expr function to parse a subexpression recursively.
That closes up the calculator example. Here's the entire source code for the parser portion of the example:

And how do we know what funds to secure if we can't get a straight answer as to how far back to go? We just guess and hope?(edited)

again, why is pbca blocked from private channels and there is no communication with him?
zaius33305-Jun-19 03:05 AM
I guess we wont be collecting staking rewards for a while
dukeleto05-Jun-19 03:05 AM
As far as I remember, the KMD web wallet is not recommended for amounts over 10KMD, is that correct?
siu - Chainmakers05-Jun-19 03:05 AM
web wallet is agama lite
ComputerGenie 👴👴👴05-Jun-19 03:05 AM
again, why is pbca blocked from private channels and there is no communication with him?
because he's the one that feked up?

And how do we know what funds to secure if we can't get a straight answer as to how far back to go? We just guess and hope?
it was said last 2, 3, 4 months - assume last 4 months... u have seed, u used in agama lite in last 4 months -> move funds
CheeseBaby05-Jun-19 03:05 AM
can collect verus staking coins

why is web wallet being recommended if its exactly the same code... in some cases much more out dated that latest release
mrlynch05-Jun-19 03:05 AM
if in doubt go balls deep

im sure it is
wallets using old code will not work with latest electrumx release
SHossain05-Jun-19 03:11 AM
If you have already used Agama in the last 2 months with that seed than its "ok" to use it again to move the funds. If you have not used it for more than 4 months then you can leave them just on the seed. We recommend moving all funds (all coins) out
Use Verus version of Agama - https://veruscoin.io/wallet.html
0. Start VRSC Lite mode
1. create new seed which will generate new address which is compatible with KMD and all assetchain. Keed the seed safely backedup (make a note of that address)
2. Send all KMD and assetchains funds to that address, even if Verus wallet doesn't support that coin at the moment. As long as you have the seed safe, you can access your funds later. Use this link to see all your assetchain balance https://dexstats.info/assetviewer.php
Agama webwallet ONLY to send funds out immediately https://www.atomicexplorer.com/wallet/#/
You can also use this guide to send all KMD and assetchains to new address. You don't need to use 2 computers. Just use one offline computer https://support.komodoplatform.com/en/support/solutions/articles/29000026631-sign-transactions-offline-and-broadcast-online-using-agama
only release of agama that is know to work 100% with latest electrumx methods is the latest.

ResoluteCrypto05-Jun-19 03:16 AM
I want answers now as well, but I’m sure the team is making sure they know the full scope of the issue before making any statements that could backfire on them. They obviously will also need time to put together a well worded explanation to try to minimize damage/panic. Thats probably why this has only been disclosed in discord and not anywhere else. Good luck everyone, be safe and move your funds if necessary

@Jcharming use any method
Jcharming05-Jun-19 03:35 AM
Thank you, so just to clarify using the desktop Agama to move them out of my address won't put them at risk or something crazy?
zaius33305-Jun-19 03:36 AM
Is there going to be an update to agama wallet in the future?
Jcharming05-Jun-19 03:36 AM
Not trying to be hasty and do something irreversible, just not familiar with verus wallet, or any version of agama that isn't the desktop lite version
SHossain05-Jun-19 03:37 AM
Verus Agama is a fork of our Agama
same experience
webwallet is also same(edited)

@Jcharming no risk but never use that seed again. That is what we know as of right now. Right now seems ppl have issues with desktop but have had success using web wallet to transfer coins out

@DLT Novice check my pinned post
@27aume native mode is not affected. unless you used the privatekey of your native wallet to login into Agama lite mode

My name is Tristian Scheepers and I am 17 years old. I am a student at The Cape Academy of Maths, Science and Technology.
I started out my high school career at HeathField High, which - don't get me wrong - wasn't the best decission. I did my grade 8-9 their. When I was in grade 8, I thought that the work was too much and we got too many pages of work. so I kind of became a reble. As teenagers, we think that we are soo "grown up" and no one can tell us what we can and can't do or what we must do. So I started not doing my homework, I gave my teachers a hard time, and i would just do what ever I wanted to do.
I started bunking classes and then school after a while. My class teacher eventually phoned my parents and told them about my bunking of classes, which didn't strike them to well.
My grade 9 year was one of my best years at school. I made many friends the previous, so now i basically knew everyone on the school. when this happens, you tend to do what ever you want because its your second year on the school and you have a lot of friends. My class and i would even bunk our different classes that we got, and then go hide away from the teacher and sit or lay on the field. Life was all good
At the end of grade 9 I got 98% for my final mark in Maths. I told one of my swimming coaches about this and told me "What are doing at HeathField High when you can be at The Cape Academy of Maths, Science and Technology". He is a teacher their, and teaches CAT and IT.
I decided to send in an application form which he gave in for me. The school accepted me for grade 10 - they start at grade 10.My grade 10 year was alright except that my marks weren't as good as what they were at my old high school.
In the june holidays of 2013, a matriculant girl from my school named Natalie McClean added me on Facebook. We started to get to know eachother a little bit at a time and finally got together in the end.

StatementBuilder¶
The library supports statement building injection, allowing the developers to override the default query statement the library is using. By default, the library is using the SqlServerStatementBuilder that is only working for SQL Server databases.
QueryBuilder¶
A query builder is an helper object used when creating a query statement in the statement builders. It contains important methods that is very useful to fluently construct the statement.
Below is a sample code that creates a SQL Statement for the Query operation for Oracle data provider.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 | public string CreateQuery(QueryBuilder queryBuilder,
string tableName,
IEnumerable<Field> fields,
QueryGroup where = null,
IEnumerable<OrderField> orderBy = null,
int? top = null,
string hints = null)
{
// There should be fields
if (fields?.Any() != true)
{
throw new NullReferenceException(string.Concat("The list of queryable fields must not be null for '", tableName, "'."));
}
// Build the query
queryBuilder
.Clear()
.Select()
.TopFrom(top)
.FieldsFrom(fields)
.From()
.TableNameFrom(tableName);
// Build the query optimizers
if (hints != null)
{
// Write the hints here like: queryBuilder.WriteText(hints);
}
// Add all fields for WHERE
if (where != null)
{
queryBuilder.WhereFrom(where);
}
// Add the ROWNUM (TOP in SQL Server)
if (top > 0)
{
// In Oracle, SELECT [Fields] FROM [Table] WHERE [Fields] AND ROWNUM <=(Rows)
if (where != null)
{
queryBuilder.WriteText(string.Concat("AND (ROWNUM <= ", top, ")"));
}
else
{
queryBuilder.WriteText(string.Concat("(ROWNUM <= ", top, ")"));
}
}
// Build the filter and ordering
queryBuilder
.OrderByFrom(orderBy)
.End();
// Return the query
return queryBuilder.GetString();
}
|
Customizing a Builder¶
The main reason why the library supports the statement builder is to allow the developers to implement or override (the default) statement builder of the DB Provider. By default, the library statement builder is only limited for SQL Server providers (as SQL Statements).
However, it will fail if the library is being used to access the SqLite, PostgreSql, MySql or any other DB Providers.
Note: The support for other DB Provider is available as Nuget Package as (MySql => RepoDb.MySql, SqLite => RepoDb.SqLite, PostgreSql => RepoDb.PostgreSql).
To create a custom statement builder, simply create a class and implements the IStatementBuilder interface.
1 2 3 4 | public class PostgreSqlStatementBuilder : IStatementBuilder
{
// Implements the IStatementBuilder methods here
}
|
Once the custom statement builder is created, it then can be used as an injectable object into the repository. See sample below injecting a statement builder for PostgreSql DB Provider.
1 2 | var statementBuilder = new PostgreSqlStatementBuilder();
var repository = new DbRepository<NpgsqlConnection>(@"Server=.;Database=Northwind;Integrated Security=SSPI;", statementBuilder);
|
With the code snippets above, everytime the repository operation methods is being called, the PostgreSqlStatementBuilder corresponding method will be executed.
StatementBuilderMapper¶
This class is used to map an existing IStatementBuilder into a specific DB Provider. The mapper is of static class.
1 | StatementBuilderMapper.Map(typeof(MySqlConnection), new MySqlStatementBuilder());
|
Note: By default, the library has mapped the SqlServerStatementBuilder object for SQL Server DB Provider (via SqlConnection).
Let say, the developers has created the following statement builder:
- SqlServerStatementBuilder (for SqlConnection)
- SqLiteStatementBuilder (for SqLiteConnection)
- MySqlStatementBuilder (for MySqlConnection)
- PostgreSqlStatementBuilder (for NpgsqlConnection)
Then, in order to utilize the mentioned statement builders, the code below must be called.
1 2 3 4 | StatementBuilderMapper.Map(typeof(SqlConnection), new SqlServerStatementBuilder());
StatementBuilderMapper.Map(typeof(SqLiteConnection), new SqLiteStatementBuilder());
StatementBuilderMapper.Map(typeof(MySqlConnection), new MySqlStatementBuilder());
StatementBuilderMapper.Map(typeof(NpgsqlConnection), new PostgreSqlStatementBuilder());
|
Injecting to Repository¶
To inject the statement builder to repository, simply passed the instance of IStatementBuilder object when initializing a repository object.
For DbRepository<TDbConnetion>:
1 2 | var statementBuider = new MySqlStatementBuilder();
var repository = new DbRepository<MySqlConnection>(ConnectionString, statementBuilder);
|
For BaseRepository<TEntity, TDbConnetion>:
1 2 3 4 5 6 7 8 9 10 | public class CustomerRepository : DbRepository<Customer, MySqlConnection>
{
public CustomerRepository(string connectionString,
IStatementBuilder builder)
: base(connectionString, builder) { }
...
}
var statementBuider = new MySqlStatementBuilder();
var repository = new CustomerRepository<MySqlConnection>(ConnectionString, statementBuilder);
|
BaseStatementBuilder¶
This class is a pre-implemented abstract class that can be used as a base implementation of the IStatementBuilder.
This is very useful if the developer would like to implement his/her own DB Provider Statement Builder.
Remember that not all implementations are meant for all DB Providers, so the developer must be aware to override certain methods if necessary.
Example: The CreateTruncate() method is using the TRUNCATE keyword when composing a SQL Statement.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | public virtual string CreateTruncate(QueryBuilder queryBuilder,
string tableName)
{
// Guard the target table
GuardTableName(tableName);
// Initialize the builder
var builder = queryBuilder ?? new QueryBuilder();
// Build the query
builder.Clear()
.Truncate()
.Table()
.TableNameFrom(tableName, DbSetting)
.End();
// Return the query
return builder.GetString();
}
|
That code will not work for SqLite. The developer must override that method if he/she is implementing his/her own statement builder.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | public override string CreateTruncate(QueryBuilder queryBuilder,
string tableName)
{
// Ensure with guards
GuardTableName(tableName);
// Initialize the builder
var builder = queryBuilder ?? new QueryBuilder();
// Build the query
builder.Clear()
.Clear()
.Delete()
.From()
.TableNameFrom(tableName, DbSetting)
.End()
.WriteText("VACUUM")
.End();
// Return the query
return builder.GetString();
}
|
Note: The CreateBatchQuery, CreateMerge and CreateMergeAll is being implemented as abstract method, whereas the others were implemented as virtual methods.

update: I got another “This is not working for me ” email regarding the MVW that is the Trentonian. I tried via CDL myself and got a big blank screen where the viewer should be (see screenshot, and also has the time). it took close to 5 minutes to load and become visible to me. I'm not sure if the patrons are waiting that long? This is the first time something like this has happened for me for this item.
A couple of things to add based on running this week. When resolving an error from a job like this it's helpful to also delete the job in sidekiq to keep the error from occurring again.
Also, when renaming the file for CDL, the file needs to be moved up a level, out of the ingesting
directory. See https://github.com/pulibrary/figgy/blob/88e37c0fcdd42dbf39e65d772338e155f0a63d1d/app/resources/cdl/automatic_ingester.rb#L16-L20
