Free text based software for linux

Tartan is a text parsing engine targeted at wiki text. The syntax specification is defined in YAML in the form of regex-based rules.

It supports layering and multiple output types. Rules for Markdown to HTML are included, with optional layered extensions for tables. Tartan text parser is implemented in Ruby, but looking to have implementations in other languages.

textTHaCAA is a system for Computers Apart Automatically and Telling Humans that was inspired by CAPTCHA from Carnegie Mellon.
Unlike image-based problems which can be difficult for people with certain disabilities, it is designed to be accessible to all users.
It achieves this by asking simple randomly generated text-based multiple choice questions where the user has to select the members of one group from a list randomly selected from members of a series of different groups.
Enhancements:
- The way the system is seeded was optimized.

OpenTranscribe is software to aid musicians in transcribing music. It lets you slow down a part of the music without affecting pitch.
It also lets you loop over a section which has some tricky parts. OpenTranscribe was inspired by the Transcribe! software published by Seventh String Software.
The software provides looping and slowing down function that eases the process of transcribing music.
At first I planned for a GUI application, but lack the skills for it. So I have created a "library" on top of some other libraries that enables the basic functionality required. And I have coded a text based client which is adequate for my own use on top of the library. The text based client is named "tot" (Text Open Transcribe).
Check the INSTALL file for dependancies and TODO file for stuffs that I have in mind but have no time to implement.
Enhancements:
- MP3 is supported.

Text::ScriptTemplate is a standalone ASP/JSP/PHP-style template processor.

SYNOPSIS

use Text::ScriptTemplate;

$text = . # - also supports variable expansion
< % } % >
EOF

$tmpl = new Text::ScriptTemplate; # create processor object
$tmpl->setq(TEXT => "hello, world"); # export data to template

# load, fill, and print expanded result in single action
print $tmpl->pack($text)->fill;

This is a successor of Text::SimpleTemplate, a module for template- based text generation.

Template-based text generation is a way to separate program code and data, so non-programmer can control final result (like HTML) as desired without tweaking the program code itself. By doing so, jobs like website maintenance is much easier because you can leave program code unchanged even if page redesign was needed.

The idea of this module is simple. Whenever a block of text surrounded by (or any pair of delimiters you specify) is found, it will be taken as Perl expression, and will be handled specially by template processing engine. With this module, Perl script and text can be intermixed closely.

Major goal of this library is to provide support of powerful PHP-style template with smaller resource. This is useful when PHP, Java/JSP, or Apache::ASP is overkill, but their template style is still desired.

Text::Query::BuildSQL is a base class for SQL query builders.

SYNOPSIS

package Text::Query::BuildSQLsqldb;

use Text::Query::BuildSQL;

use vars qw(@ISA);

@ISA = qw(Text::Query::BuildSQL);

Defines all the build_* functions to build a syntax tree. The tree nodes are [ operator scope operand operand... ]. The build_final_expression function translate the syntax tree in a where clause using the resolve method. If the scope of the search is not specified (simple query or advanced query without scope operator), the scope is set to the list of comma separated fields provided by the -fields_searched option. The resulting where clause is placed in the select order provided with the -select option, if any.

SYNTAX TREE

The string enclosed in single quotes must match exactly. The < string > token stands for an arbitrary string. A description enclosed in [something ...] means repeated 0 or N times.

expr: or scope expr [expr ...]
and scope expr [expr ...]
not scope expr
near scope expr_literal expr_literal
forbiden scope expr_literal [expr_literal ...]
mandatory scope expr_literal [expr_literal ...]
optional scope expr_literal [expr_literal ...]
literal scope < string >

expr_literal: literal scope < string >

scope: < string >

METHODS

resolve([], Q1)

Returns a where clause string corresponding to the Q1 syntax tree.

sortplusminus([], Q1)

Translate the mandatory and forbiden syntactic nodes to their boolean equivalents. If it has_relevance returns false and there is at least one mandatory word, the first mandatory word is added to the list of optional words.

has_relevance()

Returns true if relevance ranking is possible, false if not. It is used by the sortplusminus function. Returns false by default.

If relevance ranking is not possible, the semantic of the simple search is slighthly modified. When asking for +a b c it shows all the documents containing a and (b or c).

The normal behaviour is to return all the documents containing a and to sort them to show first those containing (b or c). When relevance ranking is not available the b, c search terms are therefore useless. That is why we decided to change the semantic of the query if no relevance ranking is available.

OPTIONS

-select STRING

If provided the string returned by build_final_expression substitutes the __WHERE__ tag with the where string generated by the resolve function. The substituted string is the return value of the build_final_expression.

If not set the return value of the build_final_expression is the result of the resolve function.

-fields_searched FIELDS_LIST

FIELDS_LIST is a list of comma separated field names. It is used as the default scope if no scope is provided in the query string. The build_final_expression function will croak if this option is not provided and no scope operator were used.

Text::MicroMason::ServerPages Perl module contains an alternate syntax like ASP/JSP Templates.

SYNOPSIS

Instead of using this class directly, pass its name to be mixed in:

use Text::MicroMason;
my $mason = Text::MicroMason::Base->new( -ServerPages );

Use the standard compile and execute methods to parse and evalute templates:

print $mason->compile( text=>$template )->( @%args );
print $mason->execute( text=>$template, @args );

Server Pages syntax provides another way to mix Perl into a text template:

< % my $name = $ARGS{name};
if ( $name eq Dave ) { % >
Im sorry
Good < %= $daypart % >, < %= $name % >!
< % } % >

This subclass replaces MicroMasons normal lexer with one that supports a syntax similar to Active Server Pages and Java Server Pages.

Compatibility with Apache::ASP

Apache::ASP is a full-featured application server toolkit with many fatures, of which only the templating functionality is emulated.

This is not a drop-in replacement for Apache::ASP, as the implementation is quite different, but it should be able to process some existing templates without major changes.

The following features of EmbPerl syntax are supported:

Angle-bracket markup tags

The following syntax features of are not supported:

Dynamic XML/XSL processing.

Web server objects such as $Session, $Request, $Response, and $Application.

Application events such as Application_OnStart, Script_OnStart, and other gloga.asa features.
