Free perl regexp software for linux

Visual REGEXP project can easily design and debug regular expressions by providing a graphical visualization of the expression and its matches on a sample of your choice.
Version restrictions:
- some regexp can consume a lot of CPU time. This seems to be caused by the use of -all, -inline and -indices flags together.
- when a subexpression is not matched (empty match), the last character of the previous match are coloured. This is due to a problem in Tcl (bug submitted to Scriptics).
Enhancements:
- new version done by Martin Lemburg. Many thanks, Martin.
- it is now a tcl 8.5a4 starpack
- GUI layout changed to be based on a paned window
- GUI code looks different, to be more ergonomic
- the informational labels (replacements & matches) are now sunken
- there are now additional the "first" and "last" navigation buttons
- there is a new option to navigate through matches or matches and submatches
- the displayed count of matches is changed to display the current and the count of matches used for navigation (probably changes, if the new navigation option is changed)
- the replace widget is disabled on startup
- the tcl console is added to the help menu
- the key bindings inside the regexp text widget changed a bit to allow for expanded regexp (-expanded or (?x)) to contain tabs and newlines. Tabs are created with Control-Tab and newlines with Control-Return. Additional with Control-C|V|X (not c|v|x) it is possible to use the clipboard like with Control|Shift-Insert, Shift-Delete.

Search::Tools::RegExp is a Perl module to build regular expressions from search queries.

SYNOPSIS

my $regexp = Search::Tools::RegExp->new();

my $kw = $regexp->build(the quick brown fox);

for my $w ($kw->keywords)
{
my $r = $kw->re( $w );

# the word itself
printf("the word is %sn", $r->word);

# is it flagged as a phrase?
print "the word is a phrasen" if $r->phrase;

# each of these are regular expressions
print $r->plain;
print $r->html;
}

Build regular expressions for a string of text.
All text is converted to UTF-8 automatically if it isnt already, via the Search:Tools::Keywords module.

Perl OpenID is a perl module for verifying OpenID identities.
Main features:

- Does not depend on underlying web framework
- Extensive documentaion
- Ready-to-use store implementation
- Test suite
- Licensed under the LGPL
Enhancements:
- This release contains a tested, documented library with support for OpenID extensions and Yadis.

Regexp::Log is a Perl base class for log files regexp builders.

SYNOPSIS

my $foo = Regexp::Log::Foo->new(
format => custom %a %b %c/%d,
capture => [qw( host code )],
);

# the format() and capture() methods can be used to set or get
$foo->format(custom %g %e %a %w/%s %c);
$foo->capture(qw( host code ));

# this is necessary to know in which order
# we will receive the captured fields from the regexp
my @fields = $foo->capture;

# the all-powerful capturing regexp :-)
my $re = $foo->regexp;

while () {
my %data;
@data{@fields} = /$re/; # no need for /o, its a compiled regexp

# now munge the fields
...
}

Perl Playlist is a command line application to generate m3u files based on your all your MP3s.

Perl Playlist uses MP3::Info to read the MP3 tags.

Perl playlist maker was designed to build a playlist on a remote machine that does not have a screen or X windows.

Parse::RandGen::Regexp is a Perl module for regular expression Condition element.

Regexp is a Condition element that matches the given compiled regular expression. For picking random data, the regular expression is parsed into its component Subrules, Literals, CharClasses, etc.... Therefore, the pick functionality for a regular expression is ultimately the same as the pick functionality of a Rule (including the limitations w/r to greediness - see Rule).

Regexp is also useful as a standalone class. It supports captures (named and indexed), which can be referenced in a call to the pick() function to force the captures to match the specified data, while leaving the rest of the data to be generated randomly.

METHODS

new

Creates a new Regexp. The first argument (required) is the regular expression element (e.g. qr/foo(bar|baz)+d{1,10}/). All other arguments are named pairs.

element

Returns the Regexp element (i.e. the compiled regular expression itself).

numCaptures

Returns the number of captures (e.g. $1, $2, ...$n) in the regular expression.

nameCapture

Give names to capture numbers for the regular expression. The arguments to this function are capture# => "name" pairs (e.g. nameCapture(1=>"directory", 2=>"file", 3=>"extension")).

capture

Returns the Rule object that represents the specified capture. The capture can be specified by number or by name (the name is set by the nameCapture() function).

pick

Randomly generate data (text) that matches (or does not) this regular expression.
Takes a "match" boolean argument that specifies whether to match the regular expression or deliberately not match it.

Also takes a "captures" hash argument that has pairs of capture numbers (or names) and their desired value. This allows the generated data to have user-specified constraints while allowing the rest of the regular expression to choose random data. If "match" is false, the user-specified "captures" values are still used (which may cause the data to match even though it was not supposed to).

Example:
$re->pick(match=>1,
captures=>{ 1=>"http", 2=>"www", 3=>"yahoo", 4=>"com" });

Davids Perl Games project is a collection of ASCII graphics arcade style games written in Perl.

These games are recreations of simple ASCII graphics games originally written in BASIC.

They are ideal for use as Perl programming tutorials. Some of the first few games are PerlBlaster (defend your planet from invading aliens), PerlRacer (steer your car through the twisting passages), and PerlArena (eliminate the mutant hordes).

Regexp::Parser is a Perl module for parsing regexes.

This module parses regular expressions (regexes). Its default "grammar" is Perl 5.8.4s regex set. Grammar is quoted because the module does not so much define a grammar as let each matched node state what it expects to match next, but there is not currently a way of extracting a complete grammar. This may change in future versions.

This module is designed as a replacement (though not drop-in) for my old YAPE::Regex modules.

USAGE:

Creating an Instance

To use this module as is, load it, and create an instance:

use Regexp::Parser;
my $parser = Regexp::Parser->new;

Setting a Regex

To have the parser work on a specific regex, you can do use any of the following methods:

$parser = Regexp::Parser->new($regex)

You can send the regex to be parsed as the argument to the constructor.

$parser->regex($regex)

Clears the parsers memory and sets $regex as the regex to be parsed.

These two approaches do an initial pass over the regex to make sure it is well-formed -- any warnings or errors will be determined during this initial pass.
