Free visual thesaurus software for linux

Biblio::Thesaurus is a Perl extension for managing ISO thesaurus.

SYNOPSIS

use Biblio::Thesaurus;

$obj = thesaurusNew();
$obj = thesaurusLoad(iso-file);
$obj = thesaurusRetrieve(storable-file);
$obj = thesaurusMultiLoad(iso-file1,iso-file2,...);

$obj->save(iso-file);
$obj->storeOn(storable-file);

$obj->addTerm(term);
$obj->addRelation(term,relation,term1,...,termn);
$obj->deleteTerm(term);

$obj->isDefined(term);

$obj->describe( { rel=NT, desc="Narrow Term", lang=>"UK" } );

$obj->addInverse(Relation1,Relation2);

$obj->order(rela1, rel2, ....);
@order = $obj->order();

$obj->languages(l1, l2, ....);
@langs = $obj->languages();

$obj->baselang(l);
$lang = $obj->baselang();

$obj->topName(term);
$term = $obj->topName();

$html = $obj->navigate(+{configuration},%parameters);

$html = $obj->getHTMLTop();

$output = $obj->downtr(%handler);
$output = $obj->downtr(%handler,termo, ... );

$obj->appendThesaurus("iso-file");
$obj->appendThesaurus($tobj);

$obj->tc(termo, relation1, relation2);
$obj->depth_first(term, 2, "NT", "UF")

$latex = $obj->toTex( ...)
$xml = $obj->toXml( ...)

ABSTRACT

This module provides transparent methods to maintain Thesaurus files. The module uses a subset from ISO 2788 which defines some standard features to be found on thesaurus files. The module also supports multilingual thesaurus and some extensions to the ISOs standard.

A Thesaurus is a classification structure. We can see it as a graph where nodes are terms and the vertices are relations between terms.

This module provides transparent methods to maintain Thesaurus files. The module uses a subset from ISO 2788 which defines some standard features to be found on thesaurus files. This ISO includes a set of relations that can be seen as standard but, this program can use user defined ones. So, it can be used on ISO or not ISO thesaurus files.

Visual Turing Machine project is a program that lets you create Turing machines with a point and click interface instead of using esoteric languages.
You can pack your complex machines into small boxes, and then reuse them as part of a bigger machine. VTM also features an infinite length tape.
Enhancements:
- New features include an n-ary set of symbols, multiple windows (MDI), a huge workspace (10000x10000 pixels) without a memory issue, the ability to edit your own machines, the ability to execute machines n times (where n is undefined), the ability to use expressions (like n+5) to execute machines, the ability to execute machines at desired speeds, statistics to see how many instructions were executed and how much tape was "used", and an easy wasy to translate the program to other languages.

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.

Text::VisualWidth is a Perl module that provides functions to treat half-width and full-width characters and display correct size of text in one line on terminals and mobile phones. You can know the visual width of any text and truncate text by the visual width.

Now this module support EUC-JP and UTF-8 and tested only with Japanese.

VisLib is a GTK application for visualizing, editing, and searching hierarchically-organized couples of visual and textual information, from family or holiday photographs, desktop backgrounds, digital comics, to material samples or bacterial cultures photographs.
Enhancements:
- Record and category edition works. File saving in VLB-1 format works.
- Categories and record reordering tools were added and work.
- The edit menu has been completed.
- The full loop between file creation, filling, edition and saving is operational.
