module Check::CheckableStatic
Overview
Mixin that adds .check
method to be used with a Hash
.
The idea is to check a Hash
against rules defined with Check.rules
plus executing custom checkers defined with Checker
annotation.
Defined in:
checkable.crInstance Method Summary

Checks and clean the
Hash
for its fields corresponding to class variables that have a.check_{{field}}
method. -

Instance Method Detail
Lifecycle method triggered after each call of .check
.
This method (in static call) must returns the cleaned Hash
which is provided in the third argument.
You can update this cleaned hash but you have to return it.
# Triggered on a static call: `User.check(h)` (with a `Hash` or `JSON::Any`)
def self.after_check(v : Check::Validation, h, cleaned_h, required : Bool = true, format : Bool = true) : Hash
# Code...
pp cleaned_h
cleaned_h # <= returns cleaned_h!
end
Lifecycle method triggered before each call of .check
.
# Triggered on a static call: `User.check(h)` (with a `Hash` or `JSON::Any`)
def self.before_check(v : Check::Validation, h, required : Bool = true, format : Bool = true)
# Code...
pp h
end
Checks and clean the Hash
for its fields corresponding
to class variables that have a .check_{{field}}
method.
It instantiates a Check::Validation
(if not provided) and calls all methods
related to .rules
and then methods defined with annotation Checker
.
Lifecycle methods .before_check
and .after_check
that are called
respectively at the beginning and at the end of the process.
format is used to tell cleaners generated by Check.rules
to execute format method if it has been defined.
Same as #check
but this method raises a Check::ValidationError
if the validation fails or if the clean has not been processed successfully.
cleaned_h = MyCheckable.check!(h)
Same as #check
but this method raises a Check::ValidationError
if the validation fails or if the clean has not been processed successfully.
cleaned_h = MyCheckable.check!(v, h)
Same as #check
but this method raises a Check::ValidationError
if the validation fails or if the clean has not been processed successfully.
cleaned_h = MyCheckable.check!(h)
Returns a json Hash
from a JSON input.
The return type is a tuple with a bool as a first argument indicating
that the JSON.parse
has been processed successfully or not and the 2nd
argument is the json Hash.
ok, user_h = User.h_from_json(json) # => true, {"username" => "Bob", "email" =><EMAIL_ADDRESS>Returns a json Hash
from a JSON input.
Same as #h_from_json
, except that this method raises a JSON::ParseException
if the conversion fails.
user_h = User.h_from_json!(json) # => {"username" => "Bob", "email" =><EMAIL_ADDRESS>Returns a new Hash
with all JSON keys converted to Crystal keys.

10.4. Customizing Your Key BindingsPerhaps the most common things that Emacs users want to customize are the keystrokes that cause commands to run. Keystrokes are associated with commands via key bindings. Actually, every keystroke runs a command in Emacs. Printable character keys (letters, numerals, punctuation, and spaces) run the self-insert-command, which merely causes the key just pressed to be inserted at the cursor in the current buffer. (You could play a nasty April Fool's joke on a naïve Emacs user by changing the bindings of their printable characters.) The default set of key bindings is adequate for most purposes, of course, but there are various cases in which you may want to add or change key bindings. Emacs contains literally hundreds of commands, only some of which have key bindings. As you know, you can access those that don't have bindings by typing M-x command-name Enter. If, however, you intend to use an unbound command often, you may want to bind it to a keystroke sequence for convenience. You may want to set special keys, such as arrow, numeric keypad, or function keys, to perform commands you use often. The other important concept you need to know now is that of a keymap, which is a collection of key bindings. The most basic default key bindings in Emacs are kept in a keymap called global-map. There is also the concept of a local keymap, which is specific to a single buffer. Local keymaps are used to implement commands in modes (like C mode, text mode, shell mode, etc.), and each such mode has its own keymap it installs as the local map when invoked. When you type a key, Emacs first looks it up in the current buffer's local map (if any). If it doesn't find an entry there, it looks in global-map. If an entry for the key is found, its associated command is run. What happens with commands that are bound to multiple keystrokes, as in C-x k for kill-buffer? The answer is that the keys C-x, Esc, and C-c are actually bound to special internal functions that cause Emacs to wait for another key to be pressed and then to look up that key's binding in another map; they also cause messages like C-x- to appear in the minibuffer if more than a second passes before the next key is pressed. The additional keymaps for C-x and Esc are called ctl-x-map and esc-map,[1] respectively; C-c is reserved for local keymaps associated with modes like C mode and shell mode.
For example, when you type Esc d or M-d, Emacs looks it up in the buffer's local keymap. We will assume it doesn't find an entry there. Then Emacs searches global-map; there it finds an entry for Esc with a special function (called ESC-prefix) that waits for the next keystroke and uses esc-map to determine which command to execute. When you type d, ESC-prefix looks up the entry for d in esc-map, finds kill-word, and runs it. You can create your own key bindings by adding entries in keymaps (or overriding existing ones). Three functions are available for doing this: define-key, global-set-key, and local-set-key. Their forms are: (define-key keymap "keystroke" 'command-name) (global-set-key "keystroke" 'command-name) (local-set-key "keystroke" 'command-name) Notice the double quotes around keystroke and the single quote preceding command-name. This is Lisp syntax; for more details, see Chapter 11. The keystroke is one or more characters, either printable or special characters. For the latter, use the conventions in Table 10-2.
Thus, the string abc\C-a\ndef is equal to abc, C-a, newline, and def, all concatenated into one string. Note that control characters are case-insensitive—that is, \C-A is the same thing as \C-a. However, the characters that follow control characters may be case-sensitive; \C-ae could be different from \C-aE, for example. The function define-key is the most general because it can be used to bind keys in any keymap. global-set-key binds keys in the global map only; since there is only one global-map, (global-set-key ...) is the same as (define-key global-map ...). The function local-set-key binds keys in the local map of the current buffer; it is useful only for specifying temporary key bindings during an Emacs session. Here is an example of a simple keyboard customization. Let's say you are writing code in a programming language. You compile it and get error messages that contain the line number of the error, and you want to go to that line in the source file to correct the error.[2] You would want to use the goto-line command, which is not bound by default to any keystroke. Say you want to bind it to C-x l. The command to put into your .emacs file is
(global-set-key "\C-xl" 'goto-line) This binds the l slot in ctl-x-map to the function goto-line globally—that is, in all modes. Alternatively, you can use either of the following: (define-key global-map "\C-xl" 'goto-line) (define-key ctl-x-map "l" 'goto-line) These commands have the same effect but aren't really any more efficient or better. And really, you shouldn't have to know that the keymap for C-x is called ctl-x-map. We'll stick to showing the global-set-key approach for the remaining examples, but remember that you have define-key available for situations where setting the global key is not appropriate, such as when adding a mode-specific keystroke. Other examples of key rebindings include binding C-x ? to help-command and C-h to backward-char. These key rebindings are shown below: (global-set-key "\C-x?" 'help-command) (global-set-key "\C-h" 'backward-char) Notice that these could also be done as (define-key ctl-x-map "?" 'help-command) (define-key global-map "\C-h" 'backward-char) After you put a key binding (or any other code) in your .emacs file, you need to "run" (or evaluate) the file for the change to take effect. The command for this is M-x eval-current-buffer Enter. Even better, you could press C-x C-e, which (as we will see in the next chapter) causes only the single line of Lisp code that your cursor is on to run. If you don't do either of these, the changes won't take effect until the next time you invoke Emacs. 10.4.1 Special KeysA more complicated keyboard customization task is binding commands to special keys, such as arrow, numeric keypad, or function keys, on your keyboard. This level of customization takes some work, but if you like using special keys, it is well worth the effort. Most of the special keys have reasonable names, but using them with the set key functions discussed above requires using a slightly different syntax. The name of the key appears inside square brackets rather than inside double quotes. For example, you could bind the goto-line command to the function key F5 like this: (global-set-key [f5] 'goto-line) And you can certainly use modifiers with your special keys. Control-Alt-F5 can be bound like this: (global-set-key [C-A-f5] 'goto-line) Table 10-3 lists the names of some common special keys.
10.4.2 Unsetting Key BindingsYou can also remove a particular key binding with the global-unset-key and define-key commands. For example, the following lines will both remove the goto-line command bindings from our previous examples: (global-unset-key [f5]) (define-key ctl-x-map "l" nil) Of course, you don't need to unset any bindings if you plan to replace them with something else. But this can be useful if you have a common "typo" key that you don't want firing off when you type it by mistake. |

Warning: Dev versions are less tested than stable releases and can contain bugs and other issues!
How to:
Use the Seed Generator below to create an OoT Randomizer Seed with your preferred settings,
logic options and cosmetic touches. An Ocarina of Time 1.0 NTSC-U / NTSC-J rom is
needed. OoTRandomizer.com and ZeldaSpeedRuns.com do not
distribute any copyrighted material.
Hit the Generate Seed button to start the generation process.
The Generate Race Seed button will disable the spoiler log, enable rom
encryption, and set a random seed.
You will be added to the queue. The bot will only handle a few generation requests at a
time, so bear in mind that the generation might take a minute (or more for Multiworld)
The cosmetic settings selected on generation can be overruled on the seed page itself, but
will get set as default for this seed. Your own cosmetic choices are saved for next time.
After the seed is generated, you will be forwarded to the seed page where you can check the
generated settings, the spoiler log (given you didn't generate a race seed), and also adjust
the cosmetic and targeting settings.
Afterwards, enter the required file information and select your generation mode.
Then hit Patch Rom to generate your randomized OoT rom.
Note that for the different options to play OoTR on, you will have to configure your
platform correctly. Refer to our wiki for
more information.
Please note that rom compression is a rather resource heavy process. To be able to run the OoT
Web Randomizer smoothly, we recommend
A multi core CPU (at least 2 cores)
At least 1.5 GB of RAM (possibly more)
An updated Browser (Chrome v69+, Firefox v63+, Edge (Chromium branch only), Opera v56+,
Safari 10+)
A 64 Bit system is preferred, 32 Bit support cannot be guaranteed
Mobile Devices are supported, but will slow down the patching process (Android phones with
2GB+ RAM, iPhone 5 or newer (iOS 10) supported)
Note: If your device barely fulfills the requirements, the patching process can take up to 90
seconds.


Going to post this article about C++0x suffix return types on my blog later, and I thought I'd put it here too. I'm guessing most of the readers of the article section already know it - if so then hopefully you can help me iron out any mistakes :)
From SFMLCoder:
http://sfmlcoder.wordpress.com/
-------------------------------------------------------------------------------
Time for another little C++0x feature. Like
auto, it is supported by Microsoft Visual C++ 2010 and MinGW. If you have a different compiler, then you can't go wrong by trying it anyway. Just remember that if you get compiler errors, it could mean the feature isn't supported by your compiler.
Let's get straight to it with an example. Consider the following example of how we would normally code a function:
1 2 3 4 5
|
bool Init()
{
// etc
return true;
}
| |
And here is the way using trailing return types:
1 2 3 4 5
|
auto Init() -> bool
{
// etc
return true;
}
| |
Why would we want to do this? It's more work after all. Well yes, it is more work in this case, but now consider a real world example. In my game engine's log, I have a function which takes a string, applies some formatting to it and returns it. The string type is a
typedef
'd
std::string
called
String
in the
Icanos::System
namespace.
This is how I had written the function before I took advantage of this C++0x feature.
1 2 3 4
|
Icanos::System::String Icanos::System::FormattedLog::ApplyIndent(const String& message, const String& source)
{
// etc
}
| |
I have to qualify the
String
return type in full. But if I could put the return type after, the String type would already be in scope as we've qualified the function's scope, thus simplifying notation.
1 2 3 4
|
auto Icanos::System::FormattedLog::ApplyIndent(const String& message, const String& source) -> String
{
// etc
}
| |
After the function name, everything in
Icanos::System
is already in scope, so we don't need to qualify the namespaces on
String
again.
Now then, we might also want to use suffix return types if our return type depends on the argument types (in a template function).
Thanks to jsmith for this addition.
Naively, we should like to do this:
1 2
|
template <class S, class T>
decltype(s + t) Add(const S& s, const T& t)
| |
but of course, it will not compile, as
s and
t are not in scope. But they are in scope after the parameter list:
1 2
|
template <class S, class T>
auto Add(const S& s, const T& t) -> decltype(s + t)
| |
This is a neat way of solving this problem, and just for your reference, here is the version Stroustrup suggests in the absence of suffix return types. It is clearly inferior.
1 2
|
template <class S, class T>
decltype(*(S*)(0) + *(T*)(0)) Add(const S& s, const T& t)
| |
Well I hope you've enjoyed my introduction to suffix return types - which you may also see referred to as trailing return types. If you'd like to read more about them, check out Dr. Stroustrup's FAQ:
http://www2.research.att.com/~bs/C++0xFAQ.html#suffix-return
(Coincidentally, it was originally suggested (as noted in Stroustrup's FAQ) that suffix return types be signified using [] rather than auto. However, due to controversy, auto is suggested as an alternative. Both MinGW and Microsoft Visual C++ generate a compiler error if [] is used.)


import {FullCalendarModule} from 'primeng/fullcalendar';
FullCalendar is a wrapper around on FullCalendar 4.0.1+ so fullcalendar core needs to be included in your project. For a complete documentation and samples please refer to the fullcalendar website.
npm install @fullcalendar/core --save
FullCalendar is plugin based so install the plugins you require and define them with the options property.
npm install @fullcalendar/daygrid --save
npm install @fullcalendar/timegrid --save
npm install @fullcalendar/interaction --save
Events should be an array and defined using the events property.
<p-fullCalendar [events]="events"></p-fullCalendar>
export class MyModel {
events: any[];
ngOnInit() {
this.events = [
{
"title": "All Day Event",
"start": "2016-01-01"
},
{
"title": "Long Event",
"start": "2016-01-07",
"end": "2016-01-10"
},
{
"title": "Repeating Event",
"start": "2016-01-09T16:00:00"
},
{
"title": "Repeating Event",
"start": "2016-01-16T16:00:00"
},
{
"title": "Conference",
"start": "2016-01-11",
"end": "2016-01-13"
}
];
}
}
In a real application, it is likely to populate the events by making a service call, when the events are updated, the component will detect the change and render them.
@Injectable()
export class EventService {
constructor(private http: Http) {}
getEvents() {
return this.http.get('showcase/resources/data/calendarevents.json')
.toPromise()
.then(res => <any[]> res.json().data)
.then(data => { return data; });
}
}
export class MyModel {
events: any[];
ngOnInit() {
this.eventService.getEvents().then(events => {this.events = events;});
}
}
FullCalendar has a long list of customization parameters that are defined with the options property. Example below customizes the header property.
import dayGridPlugin from '@fullcalendar/daygrid';
import timeGridPlugin from '@fullcalendar/timegrid';
import interactionPlugin from '@fullcalendar/interaction';
export class FullCalendarDemo implements OnInit {
events: any[];
options: any;
constructor(private eventService: EventService) { }
ngOnInit() {
this.eventService.getEvents().then(events => {this.events = events;});
this.options = {
plugins: [dayGridPlugin, timeGridPlugin, interactionPlugin],
defaultDate: '2017-02-01',
header: {
left: 'prev,next',
center: 'title',
right: 'month,agendaWeek,agendaDay'
}
{;
}
}
<p-fullCalendar [events]="events" [options]="options"></p-fullCalendar>
Updates to the events or options are reflected to the UI whenever a change occurs. An important note here is that UI update only happens whenever a new instance is created on these twp properties. Simply changing the events array without creating a new instance of the array or updating a property inside options will have no effect.
update() {
//incorrect
this.events.push({
"title": "Conference",
"start": "2016-01-11",
"end": "2016-01-13"
});
//correct
this.events = [...this.events, {
"title": "Conference",
"start": "2016-01-11",
"end": "2016-01-13"
}];
//incorrect
this.options.weekends = false;
//correct
this.options = {...this.options, {weekends: false}};
}
Callbacks of the FullCalendar are also defined with the options property.
this.options = {
plugins: [dayGridPlugin, timeGridPlugin, interactionPlugin],
header: {
left: 'prev,next',
center: 'title',
right: 'month,agendaWeek,agendaDay'
},
dateClick: (e) => {
//handle date click
}
}
Methods of the underlying calendar instance is accessible using the reference of the components getCalendar() API.

@ViewChild('fc') fc: FullCalendar;
gotoDate(date: Date) {

 Our Montessori trained facilitator will cover topics such as Montessori environments, independence, toilet teaching, positive discipline, observation, weaning, language development, and more! Classes will be held twice per week and will include an observation period, a parent discussion period, and a Music Together class designed for babies and toddlers. Please contact us for pricing and more information.
A child at twelve months is just beginning to experience the world. In the next year, he or she will probably begin to walk and run, talk in simple sentences, feed him or herself, and many other milestones. The ones classroom at Alegria Montessori has been designed by our Montessori trained teachers to present your young toddler with a safe, engaging, and loving space in which to explore, gain confidence, and practice independence. We offer a language rich environment that respects the autonomy and individuality of each child in our care. Sensory experimentation and movement are encouraged, with a toddler friendly outdoor playground, covered porch, and garden.
Between the ages of 24 months and 3 years of age, a child develops explosively – body control (running, jumping, and dancing), fine motor control (tweezing, spooning, pouring, and grasping), language development (speaking in sentences and paragraphs, telling and listening to stories, and singing), and socially and emotionally (beginning to make friends and learn social graces). Your two year old is busy!
Our Montessori trained teachers offer a sensory and language rich environment that paves the way for future successes. We offer many practical life skills to a child of this age, which hones motor control and independence. At Alegria Montessori School, we have prepared a safe, friendly, and ordered classroom for your child to practice these skills and build concentration, independence, and confidence.
Tanya Rotter taught in a traditional preschool in Kentucky for 8 years before moving to Florida, working with children from 1 year to 12 years of age. She explored other career options in retail management before returning to her real love – teaching! Tanya has worked at Alegria for 6 years. Tanya is the lead teacher and site director at our Alegria Lakewood campus. She will also coordinate the Parent/Infant Education classes. Tanya attended Eckerd College, has her Child Development Associate, and has finally done her 0 – 3 Montessori training with Palm Harbor Teacher Education Center!
After babysitting and nannying for many years, Rachel fell in love with Montessori when she was introduced to Montessori Parent/Child classes. She joined Alegria in 2012. Rachel attended Palm Harbor Montessori Teacher Education Center and holds a Montessori Infant and Toddler credential. She currently attends USF and is working towards a bachelors degree in social work. Rachel is a native of St. Petersburg. She enjoys running, camping, crossfiting, and spending time outdoors.

The Perl regular expression syntax is based on that used by the programming
language Perl . Perl regular expressions are the default behavior in Boost.Regex
or you can pass the flag perl
to the basic_regex
constructor, for example:
// e1 is a case sensitive Perl regular expression: // since Perl is the default option there's no need to explicitly specify the syntax used here: boost::regex e1(my_expression); // e2 a case insensitive Perl regular expression: boost::regex e2(my_expression, boost::regex::perl|boost::regex::icase);
In Perl regular expressions, all characters match themselves except for the following special characters:
.[{()\*+?|^$
The single character '.' when used outside of a character set will match any single character except:
match_not_dot_null
is passed to the matching algorithms.
match_not_dot_newline
is passed to the matching algorithms.
A '^' character shall match the start of a line.
A '$' character shall match the end of a line.
A section beginning (
and ending
)
acts as a marked sub-expression.
Whatever matched the sub-expression is split out in a separate field by the
matching algorithms. Marked sub-expressions can also repeated, or referred
to by a back-reference.
A marked sub-expression is useful to lexically group part of a regular expression,
but has the side-effect of spitting out an extra field in the result. As
an alternative you can lexically group part of a regular expression, without
generating a marked sub-expression by using (?:
and )
, for example (?:ab)+
will repeat ab
without splitting
out any separate sub-expressions.
Any atom (a single character, a marked sub-expression, or a character class)
can be repeated with the *
,
+
, ?
,
and {}
operators.
The *
operator will match the
preceding atom zero or more times, for example the expression a*b
will match any of the following:
b ab aaaaaaaab
The +
operator will match the
preceding atom one or more times, for example the expression a+b
will match any of the following:
ab aaaaaaaab
But will not match:
b
The ?
operator will match the
preceding atom zero or one times, for example the expression ca?b will match
any of the following:
cb cab
But will not match:
caab
An atom can also be repeated with a bounded repeat:
a{n}
Matches
'a' repeated exactly n times.
a{n,}
Matches
'a' repeated n or more times.
a{n, m}
Matches 'a' repeated between n and m times
inclusive.
For example:
^a{2,3}$
Will match either of:
aa aaa
But neither of:
a aaaa
It is an error to use a repeat operator, if the preceding construct can not be repeated, for example:
a(*)
Will raise an error, as there is nothing for the *
operator to be applied to.
The normal repeat operators are "greedy", that is to say they will consume as much input as possible. There are non-greedy versions available that will consume as little input as possible while still producing a match.
*?
Matches the previous atom
zero or more times, while consuming as little input as possible.
+?
Matches the previous atom
one or more times, while consuming as little input as possible.
??
Matches the previous atom
zero or one times, while consuming as little input as possible.
{n,}?
Matches the previous atom n or more times,
while consuming as little input as possible.
{n,m}?
Matches the previous atom between n and m times, while consuming as little
input as possible.
An escape character followed by a digit n, where n is in the range 1-9, matches the same string that was matched by sub-expression n. For example the expression:
^(a*).*\1$
Will match the string:
aaabbaaa
But not the string:
aaabba
The |
operator will match either
of its arguments, so for example: abc|def
will
match either "abc" or "def".
Parenthesis can be used to group alternations, for example: ab(d|ef)
will match either of "abd" or "abef".
Empty alternatives are not allowed (these are almost always a mistake), but
if you really want an empty alternative use (?:)
as a placeholder, for example:
|abc
is not a valid expression, but
(?:)|abc
is and is equivalent, also the expression:
(?:abc)??
has exactly the same effect.
A character set is a bracket-expression starting with [
and ending with ]
, it defines
a set of characters, and matches any single character that is a member of
that set.
A bracket expression may contain any combination of the following:
For example [abc]
, will match any of the characters 'a', 'b',
or 'c'.
For example [a-c]
will match any single character in the range 'a' to 'c'. By default, for
Perl regular expressions, a character x is within the range y to z, if the
code point of the character lies within the codepoints of the endpoints of
the range. Alternatively, if you set the collate
flag when constructing the
regular expression, then ranges are locale sensitive.
If the bracket-expression begins with the ^ character, then it matches the
complement of the characters it contains, for example [^a-c]
matches any character that is not in the
range a-c
.
An expression of the form [[:name:]]
matches the named character class "name", for example [[:lower:]]
matches any lower case character. See
character class names.
An expression of the form [[.col.]
matches
the collating element col. A collating element is any
single character, or any sequence of characters that collates as a single
unit. Collating elements may also be used as the end point of a range, for
example: [[.ae.]-c]
matches the character sequence "ae", plus any single character
in the range "ae"-c, assuming that "ae" is treated as
a single collating element in the current locale.
As an extension, a collating element may also be specified via it's symbolic name, for example:
[[.NUL.]]
matches a \0
character.
An expression of the form [[=col=]]
,
matches any character or collating element whose primary sort key is the
same as that for collating element col, as with collating
elements the name col may be a symbolic
name. A primary sort key is one that ignores case, accentation, or
locale-specific tailorings; so for example [[=a=]]
matches
any of the characters: a, À, Á, Â, Ã, Ä, Å, A, à, á, â, ã, ä and å. Unfortunately implementation
of this is reliant on the platform's collation and localisation support;
this feature can not be relied upon to work portably across all platforms,
or even all locales on one platform.
All the escape sequences that match a single character, or a single character
class are permitted within a character class definition. For example [\[\]]
would match either of [
or ]
while [\W\d]
would match any character that is either a "digit", or
is not a "word" character.
All of the above can be combined in one character set declaration, for example:
[[:digit:]a-c[.NUL.]]
.
Any special character preceded by an escape shall match itself.
The following escape sequences are all synonyms for single characters:

An ASCII escape sequence - the character whose code point is X % 32 |
|
|
A hexadecimal escape sequence - matches the single character whose code point is 0xdd. |
|
|
A hexadecimal escape sequence - matches the single character whose code point is 0xdddd. |
|
|
An octal escape sequence - matches the single character whose code point is 0ddd. |
|
|
Matches the single character which has the symbolic
name name. For example |
Any escaped character x, if x is the name of a character class shall match any character that is a member of that class, and any escaped character X, if x is the name of a character class, shall match any character not in that class.
The following are supported by default:

Matches any character that does not have the property X. |
|
|
|
Matches any character that does not have the property Name. |
|
For example \pd
matches any "digit" character, as does \p{digit}
.
The following escape sequences match the boundaries of words:
\<
Matches the start of a
word.
\>
Matches the end of a word.
\b
Matches a word boundary (the start or end of a word).
\B
Matches only when not at a word boundary.
The following match only at buffer boundaries: a "buffer" in this context is the whole of the input text that is being matched against (note that ^ and $ may match embedded newlines within the text).
\` Matches at the start of a buffer only.
\' Matches at the end of a buffer only.
\A Matches at the start of a buffer only (the same as \`).
\z Matches at the end of a buffer only (the same as \').
\Z Matches an optional sequence of newlines at the end of a buffer: equivalent
to the regular expression \n*\z
The sequence \G
matches only at the end of the last match found, or at the start of the text
being matched if no previous match was found. This escape useful if you're
iterating over the matches contained within a text, and you want each subsequence
match to start where the last one ended.
The escape sequence \Q
begins a "quoted sequence": all the subsequent characters are treated
as literals, until either the end of the regular expression or \E is found.
For example the expression: \Q\*+\Ea+
would match either of:
\*+a \*+aaa
\C
Matches a single code point: in Boost regex this has exactly the same effect
as a "." operator. \X
Matches a combining character sequence:
that is any non-combining character followed by a sequence of zero or more
combining characters.
Any other escape sequence matches the character that is escaped, for example \@ matches a literal '@'.
Perl-specific extensions to the regular expression syntax all start with
(?
.
(?# ...
)
is treated as a comment, it's contents
are ignored.
(?imsx-imsx ... )
alters
which of the perl modifiers are in effect within the pattern, changes take
effect from the point that the block is first seen and extend to any enclosing
)
. Letters before a '-' turn
that perl modifier on, letters afterward, turn it off.
(?imsx-imsx:pattern)
applies the specified modifiers to pattern only.
(?:pattern)
lexically groups pattern, without generating
an additional sub-expression.
(?=pattern)
consumes zero characters, only if pattern
matches.
(?!pattern)
consumes zero characters, only if pattern
does not match.
Lookahead is typically used to create the logical AND of two regular expressions, for example if a password must contain a lower case letter, an upper case letter, a punctuation symbol, and be at least 6 characters long, then the expression:
(?=.*[[:lower:]])(?=.*[[:upper:]])(?=.*[[:punct:]]).{6,}
could be used to validate the password.
(?<=pattern)
consumes zero characters, only if pattern
could be matched against the characters preceding the current position (pattern
must be of fixed length).
(?<!pattern)
consumes zero characters, only if pattern
could not be matched against the characters preceding the current position
(pattern must be of fixed length).
(?>pattern)
pattern is matched
independently of the surrounding patterns, the expression will never backtrack
into pattern. Independent sub-expressions are typically
used to improve performance; only the best possible match for pattern will
be considered, if this doesn't allow the expression as a whole to match then
no match is found at all.
(?(condition)yes-pattern|no-pattern)
attempts to match yes-pattern
if the condition is true, otherwise attempts to match
no-pattern.
(?(condition)yes-pattern)
attempts to match yes-pattern if the condition
is true, otherwise fails.
condition may be either a forward lookahead assert, or the index of a marked sub-expression (the condition becomes true if the sub-expression has been matched).
The order of precedence for of operators is as follows:
[==]
[::] [..]
\
[]
()
*
+ ? {m,n}
If you view the regular expression as a directed (possibly cyclic) graph, then the best match found is the first match found by a depth-first-search performed on that graph, while matching the input text.
Alternatively:
The best match found is the leftmost match, with individual elements matched as follows;
|
Construct |
What gets matched |
|---|---|
|
|
Locates the best match for AtomA that has a following match for AtomB. |
|
|
If Expresion1 can be matched then returns that match, otherwise attempts to match Expression2. |
|
|

Matches S repeated between N and M times, and as many times as possible. |
|

If condition is true, then only yes-pattern is considered, otherwise only no-pattern is considered. |

With its distinctive appearance and habits, the anteater has been featured in pre-Columbian myths and folktales, as well as modern popular culture.
The giant anteater (Myrmecophaga tridactyla), also known as the ant bear, is a large insectivorous mammal native to Central and South America. It is one of four living species of anteaters and is classified with sloths in the order Pilosa. This species is mostly terrestrial, in contrast to other living anteaters and sloths, which are arboreal or semiarboreal. The giant anteater is the largest of its family, 182–217 cm (5.97–7.12 ft) in length, with weights of 33–41 kg (73–90 lb) for males and 27–39 kg (60–86 lb) for females. It is recognizable by its elongated snout, bushy tail, long fore claws, and distinctively colored pelage. (Source: Wikipedia: Giant Anteater)


Murray can be Britain's Davis Cup trump card
Britain's Leon Smith could be the envy of the other 17 Davis Cup captains this week with three-time Grand Slam champion Andy Murray up his sleeve as a surprise second singles player.
MADRID: Britain's Leon Smith could be the envy of the other 17 Davis Cup captains this week with three-time Grand Slam champion Andy Murray up his sleeve as a surprise second singles player.
With Murray having undergone hip-resurfacing surgery in January in a bid to salvage his career, Smith was planning for the Madrid finals without the team's talisman.
But the 32-year-old Scot's return to top form has been faster than expected with Murray winning the European Open title in Antwerp last month.
It helped him back to 126th in the rankings, behind Britain's other two singles players in Madrid; Dan Evans who is 42nd and Kyle Edmund who is 69th.
Davis Cup rules state that singles players picked for a tie must play in order of ranking, but Smith could leave out either Evans or Edmund, allowing him the luxury of sending Murray out to play the second singles against a potentially weaker player.
No other nation in the Spanish capital will have such a cunning back-up plan.
Britain begin their campaign on Wednesday when they face the Netherlands in Group E before taking on Kazakhstan on Thursday.
Murray, who has won 30 of 33 singles rubbers for Britain, admitted playing potentially five singles matches in five days might be a step too far.
"Five days in a row would be tough just now," Murray, who almost single-handedly won the Davis Cup for Britain in 2015, said.
"I did it in Antwerp ... but it was tough."
Smith acknowledges that Murray's availability is a bonus even if Evans and Edmund have proved themselves capable of beating the best on the world.
"Sometimes in some ways you'd want to flip it around depending on the matches you're up against," he told reporters. "But it could be a positive."
Former world number one Murray, the twice Wimbledon and reigning Olympic champion, has been a stalwart of the team and the topspin lob he played to beat David Goffin in Ghent 2015 to seal Britain's first Davis Cup title for 79 years rates as one of the standout moments of his career.
That final was unforgettable for the frenzied atmosphere and energy of the fans - something only sporadically evident in Madrid where 18 nations have assembled in La Caja Magica for the first edition of the revamped competition.
The reception for the new format has so far been mixed but Murray believes people wanting to "bash" the event should reserve judgment until after Sunday's conclusion.
"In tennis sometimes we are reluctant to make changes, and this is a big change. We should give it an opportunity to see how it goes."

The allegations against Roman Polanski
PARIS, Nov 10 — A French former model and actress has accused Oscar-winning director Roman Polanski, 86, of raping her in a Swiss ski resort in 1975 when she was 18 years old.
It is the latest in a series of allegations against the director, who fled to France from the United States in 1978 after admitting to the statutory rape of a 13-year-old girl.
Here is a summary of the accusations concerning Polanski, whose award-winning film An Officer and a Spy is released in France next week.
The US rape case
On March 11, 1977, the then 43-year-old Roman Polanski is arrested and accused of having drugged and raped a 13-year-old during a photo shoot the day before. He faces up to 50 years in prison.
He is charged later that month on five counts, including rape by use of drugs and committing a lewd and lascivious act on a child under 14.
In August, to avoid a trial, Polanski pleads guilty to a single, lesser charge of unlawful sexual intercourse, an agreement reached with the judge and with the consent of the victim’s family.
Sentenced to 90 days in prison, a psychiatric evaluation concludes he is not a danger and he is released after 42 days for good behaviour.
But the day before a hearing to approve the deal, the judge changes his mind, saying he thinks the sentence was insufficient.
On January 31, 1978, Polanski flees to Paris, making use of his French citizenship. The US issues an international arrest warrant.
Polanski has since paid US$225,000 (RM929,925) to the victim, Samantha Gailey (now Geimer), to end a civil suit.
US extradition bids
US authorities have on several occasions tried to have Polanski extradited to face trial.
On September 26, 2009, he is arrested in Zurich, Switzerland, on a US-issued international warrant.
After two months in prison and eight months under house arrest at his chalet in Gstaad, in the Swiss Alps, Switzerland rejects the request in July 2010.
In 2014, Polanski is arrested in Warsaw, although Poland refuses to extradite him.
In 2016, Poland’s conservative government re-opens the case, but the Polish Supreme Court closes it in December.
Despite requests from both Polanski and Geimer, in August 2017, a Los Angeles judge refuses to close the case.
Fresh accusations
At the Cannes Film Festival in 2010, 42-year-old British actress Charlotte Lewis alleges Polanski sexually abused her when she was 16 during a casting session at his home in 1983.
In August 2017, a second woman going by the name of “Robin” accuses Polanski of sexual aggression when she was 16, in 1973.
In September 2017, Renate Langer, a 61-year-old former actress, accuses Polanski of having raped her in 1972 in Gstaad when she was 15.
The following month, California artist Marianne Barnard accuses him of sexually assaulting her in 1975 after asking her to pose naked when she was just 10 years old.
In November 2017, Swiss prosecutors rule out bringing charges over the latest allegations because the statute of limitations for the assault has expired
Polanski’s lawyer says his client denies all the allegations against him.
Oscars outlaw
Plans for Polanski to preside over the Cesars, the French equivalent of the Oscars, are abandoned in 2017, amid the fall-out from “Me Too” movement that started with accusations of sexual assault against US producer Harvey Weinstein.
Although awarded the 2003 Best Director Oscar for The Pianist, Polanski is expelled from the US Academy of Motion Picture Arts and Sciences in 2018.
The same year, his wife, actor Emmanuelle Seigner, refuses an invitation to join the Academy in protest at her husband’s treatment.
The latest accusation
On November 8, 2019, French newspaper Le Parisien carries allegations against Polanski from French former model and actress Valentine Monnier.
She says he raped her at his chalet in the Swiss ski resort at Gstaad when she was a teenager in 1975, when she was 18 years old.
While she did not file a complaint against him, she confided in two women at the time, both of whom confirmed her account to Le Parisien.
Polanski’s lawyer has said he “firmly denies all accusations of rape”. — AFP

There have been many predictions about the future of technology. My father remembers how during the 60’s and 70’s there were many people in the Soviet Union who printed their own predictions, in the popular magazines, about what technological breakthroughs there will be at the dawn of the new millennium: teleportation, lightsabers, mind-reading computers, etc, etc. Those predictions never came true. However, my father’s uncle, who was one of the leading scientists in the Soviet space program, predicted that by around the year 2000 there will be computers about the size of a book. This example illustrates that we need to base our predictions about what the future may hold for technological progress not on enthusiasm and speculations, but on practical scientific knowledge. We also need to be aware that quick bursts of technological progress, like the one we’ve seen in the 20 th and 21 st centuries are not the rule, but the exception. They are the culmination of a long process of slow evolution, and they are almost always followed by a plateau of very slow growth, or in some cases, stagnation. Ray Kurzweil, an American scientist and speculator about the future of technology, has predicted many times that within 15 years from now, humans will merge with machines in an event he calls the Singularity. Yet year after year, he keeps pushing that date farther and farther into the future. What this idea of a supposed technological breakthrough is, and why it is at best silly and at worst potentially dangerous for the human species, is the main topic of my paper.
According to Ray Kurzweil, the human species is destined to be replaced by a post-human species of robots or cyborgs. He claims that as computer and robotic technologies keep advancingexponentially, it is only a matter of time when these technologies will take over our bodies, and we will all replace our biology with cybernetics. He proposes that as a first step to this, there will be made computer chip implants that would go into the human body to supposedly get rid of its “biological flaws.” At first glance, it may seem like a harmless idea, even an improvement, but let’s consider the effects that such implants would have on the human body. Being obviously made of inorganic substances, these computer chips would affect the human body negatively. It is inevitable that these implants would leak heavy metals and other toxic compounds into the bloodstream and poison the tissues directly around them. It is worth noting that computer chips create a small, but measurable electromagnetic field. This form of ionizing radiation disrupts the body’s own biological electromagnetic vibrations, and can lead to a variety of disorders, as medical studies done on frequent users of smartphones and bluetooth headsets show. It has been shown that cancer can be caused by exposure to radiation and toxins. Over time, damage to the internal organs would result, especially if the cybernetic implants would be inserted deep inside the body. There is also the possibility of having an out of control autoimmune reaction as the body tries to get rid of a foreign object that is causing it harm. Now it is apparent why the Singularity is an issue that the Ministry of Public Healthcare should be concerned about.
Despite the obvious health issues resulting from such implants, Ray Kurzweil doesn’t stop there. He advocates the total replacement of the “inefficient” human brain with a computer. However, the brain can process information much more faster than a computer can. It is much more energy efficient too, not needing complicated liquid cooling systems like the supercomputers that hope to reach a fraction of its power. Also unlike supercomputers, the human brain obviously does not need to occupy an entire room. It is also a well-known fact that most people use only 10% of the potential of their brain. A computer machine, being a product of intelligent design, cannot possibly match the human brain, a product of millions of years of evolution, perfected by forces of adaptation and natural selection.
We humans are not machines, reacting to our environment on autopilot based on some chain of chemical reactions. There is also the mind as the non-physical part of your body, from which your consciousness stems. Computer can be programmed to do repetitive or predictable tasks using algorithms. Playing chess or calculating financial transactions are two examples of such simple and routine patterns. The human mind may not be good at crunching numbers, but it has some advantages over a software program. These include: patten recognition, creativity, reason, conscience, honor, common sense, altruism, and morality. The actions of the crew of the nuclear-powered submarine of the Russian navy, the Kursk, demonstrate these above mentioned attributes of the human mind. During a naval exercise, this submarine had an accident, and sunk to the bottom of the sea with all the crew on board. The lead engineer of the Kursk, who was in charge of maintaining the nuclear reactors which powered the vessel, faced a choice. He could either keep the power on for the crew to have a chance of escaping the sunken submarine, but risking a possible overheating and meltdown of the reactors, or turning the power off, inevitably sealing the crew’s fate to die in the submarine but saving the world from an underwater Chernobyl or Fukushima. Acting according to instructions and to his own morality, he picked the second choice. Could a robot make the right decision in this situation? Also, could a person who would go to such great lengths as to turn themselves into a robot for the case of preserving their physical existence make this decision?
Of course, the proponents of the Singularity would then cite the convenience of their artificial path of development. The human body, including the brain eventually ages and dies, while a robotized body can be made to last indefinitely. This would prolong the lifespan of an individual. I am not completely against that idea, but I think that it should be allowed only for old people, who will definitely not have children. For example, an aging prominent scientist who fears to lose their memory due to aging, could ask themselves to be robotized in order to continue making positive contributions to society. Additionally, nanobots could be used for medical diagnostics or non-invasive surgery only temporarily, but not permanently inside the human body. There are limits to where you can use atechnology. Completely replacing the healthy biological functions of the human body, with ones based on computer or robotic technology, as Ray Kurzweil suggests, is outside these limits. The strength of the human biology lies in adaptation. When you replace the product of billions of years of evolution with a simple machine, you shortcut, or rather short-circuit this process. Machines are designed only once. They cannot adapt to changing environmental circumstances. As Charles Darwin pointed out, biological reproduction, natural selection, and evolution, are the main pillars of the survival of species. The convenient artificial route, conversion of the human species to cyborgs marks the beginning of the end of its evolution. For example, one single disruption, such as a new virus could wipe out an entire population of robotized beings, because cyborgs can only exist in an artificial environment which is frozen in time, unchanging. However, everything in the Universe is changing, or adapting! The proponents of the Singularity are unable or unwilling to see this. They favor the extension of an individual’s lifespan over the best interests of the human species as a whole. This is why their idea is dangerous to the future development of humanity, and must be stopped.
What would be the opposite result, if the Singularity is allowed to go through without any resistance, and humanity becomes a species of robotized beings? To answer this question, I would like to ask our cosmic neighbors, other space-faring civilizations who are far ahead of us in terms of technology. Just like us, they too were once faced with this decision. What was their choice as a species? I would like to make a hypothesis. For example, the Fermi Paradox says that if advanced space-faring civilizations are so numerous, why do we not see tangible evidence of their presence in the outer space? Why haven’t they already colonized the entire Universe by now? Maybe the majority of these civilizations became out of sync with their environment. They chose the straight and easy path of artificiality offered by the Singularity, stopped biologically reproducing and evolving, and eventually died out. Maybe this extinction of civilizations is the cause of the Fermi Paradox. What will happen to the human species?

Getting Started¶
Hi there! Welcome to the beginning of your journey with trendPy. Before you start to learn how to use the TrendPy package you must install it on your desktop environment. Unfortunately TrendPy is not avialable via pip yet.
So you must install the package manually on your desktop or use the web app. Don’t worry. We will lead you to through this process step by step:
Manually installation on native python¶
Please follow the steps below if you have native python installed on your desktop:
First you must
download the package
Extract the downloaded .zip file in a folder you can find again.
Open the extracted trendpy-main folder. You should see a folder with the same name there.
Open this folder as well.
You should now see a folder called TrendPy
Copy this folder by clicking on it and pressing
ctrl + c
on your keyboard then.Navigate to your python directory. Depending on your pythons version the path should look like this by default installation
C:\Users\name\AppData\Local\Programs\Python\Python39
Open the
Lib
folderSearch and open the
site-packages
folder then.Paste the copied TrendPy folder into the
site-packages
folder by pressingctrl + v
on your keyboard.
Manually installation on the Anaconda distribution¶
Please follow the steps below if you use python via the Anaconda distribution:
First you must
download the package
Extract the downloaded .zip file in a folder you can find again.
Open the extracted trendpy-main folder. You should see a folder with the same name there.
Open this folder as well.
You should now see a folder called TrendPy
Copy this folder by clicking on it and pressing
ctrl + c
on your keyboard then.Navigate to your Anaconda3 directory. The path should look like this by default installation
C:\Users\name\anaconda3\
Open the
Lib
folderSearch and open the
site-packages
folder then.Paste the copied TrendPy folder into the
site-packages
folder by pressingctrl + v
on your keyboard.
Cool! You have installed the package on your desktop now.
To verify this you can open or create a python script and import the package with import TrendPy
. If no error appears
the pack age was installed successfully and you can go ahead by reading the documentation.
Web App¶
If you just want to try out the trendPy package, you can also do that in your browser.
Visit either the heroku app or the binder web app.
Once you are there, click the upload button and select your data set.
Click on “start calculation” to upload your chosen data set.
Now you can play around with the x and y variables and pick your trend line.
Once you are finished, you can save the created plot as a png via the small photo button to the right of the plot.
Congratulations, now you have a nice trend line of your choosing for your data. It’s really that simple.

---
Occasionally, I have run into 500 server errors because there is an object attribute that is nil
and I try to run a method on it. This tended to happen in my jbuilder files for returning API responses where the mobile app needed data in a certain format. Here's the simplest way to fix this:
nil.to_s
#=> Outputs “”
#to_s
on the attribute. I’m guessing this might be a slight performance hit, but probably not much more than an if/else statement would be.

Reports string literals that are replicated unchanged throughout the project.
Two quick-fixes are provided. One to introduce a constant for a duplicated string and use it throughout the project,
and one to show the location of all the duplicates of a particular string literal.
Example:
class C1 { String CONST1 = "duplicate string"; }
class C2 { String CONST2 = "duplicate string"; }
Configure the inspection:
- Use the Min string length field to set the minimal string length required to detect duplicates.
- Use the Ignore @PropertyKey expressions option to ignore strings passed as arguments to methods annotated with
org.jetbrains.annotations.PropertyKey
.

IE View Lite 1.3.2+ not compatible with Firefox 2.0
I used all sorts of add-ons and extensions for Firefox, (I’ll get around to writing a blog post on that soon too). Since I do a lot of web-development, I switch between Firefox and Internet Explorer frequently during a build.
To make this easier, I’ve been using Grayson Mixon’s IE View Lite. But with the latest upgrade (version 1.3.2), it broke in Firefox 2.0! (This made me sad) :-(
I’d been holding out for the next upgrade – to see if that would fix the problem… but nothing came.
So I emailed Grayson to see if there was a potential fix in a future release; which he promptly replied:
IE View Lite 1.3.2 and 1.3.3 are Firefox 3 only. If you want to continue using Firefox 2, you should use IE View Lite 1.3.1, the only difference being compatibility updates for Firefox 3 that broke backward compatibility.
I’ve now uninstalled version 1.3.2 – reverting back to 1.3.1 – and everything is good again! (Thanks Grayson).
It does concern me that support was dropped for Firefox 2.0 in favour of version 3 (which is still only in beta) – cutting out a large proportion of the user-base. But I guess once Firefox 3 has shipped, no one will be bothered anyway.


My Valued Friend I am Mr. Mike Ato, a Regional Branch Manager, International Commercial Bank ltd, Ghana, West Africa. I write you this letter in good faith and trust and expected you to keep it confidential. Also I hoped you will not be embarrassed as why I contacted you. I have that conviction to contacted you hoping all will be with your full co-operation. I am in control of the sum of one million, eight hundred and fifty thousand US dollars ($1,850,000),an excess profit made by our regional branch in the last quarter of the year 2004. I have carefully placed the fund in an Escrow Call Deposit Account and did not declare it to my head office, while accounting for the end of the year fiscal profits.  If you accept my offer you can contact me immediately. If you do not accept can you forget I contacted you? I want you to get me a good current account in your country where I can move this money. I will discreetly give you all the information concerning the account so that you can apply to our Head Office for the transfer of the money to your account. You shouldn't be afraid, as it will be just a smooth bank-to-bank transfer. There is practically no danger to your person. I am hoping for your perfect understanding of my situation and position. Thanks Mike
