Widget libraries have now been developed and used for years. In all these libraries, widget instances require computer memory. But this memory is not really required, We have implemented a widget library to prove that it is possible to use zero bytes of memory per widget.
In such a library, there is no widget reference, so widget programming is easier even in a low level language such as C. Programs are more robust because they do not use pointers, make no memory management and do not translate data between application and widget.
To set the attributes of a widget, it is not possible to use the widgets pointer so a current state is used as in OpenGL. Most classic widgets were integrated into the library, and it is possible to integrate widgets of all kinds without any problem.
This library license is the GNU GPL. Beware: it is alpha software. It works but the API is not yet stable.
Main features:
Base widgets:
- text, text_editable, int, int_editable,
- anchor,
- button, tearoff, button_with_accelerator,
- image, image_from_file,
- scrollbar2, scrollbar_vertical, scrollbar_horizontal,
- toggle (bit or int or char) with or without label. Same for radio button. Really easy to use.
Container widgets:
- window, window_drag, window_popup_right, window_popup_bottom
- anchor_box,
- box_horizontal, box_vertical, box,
- decorator,
- notebook,
- scrolledview (can contains billions of children)
- viewport
- table, table_with_width,
- void, if, popup : base system to make transient widgets. The menu are constructed with "popup"
Composite widgets:
- alert (container),
- message (container),
- filechooser,
Widget attributes:
- Choice of the focus group.
- Width: padding, border, focus
- Expand: vertical, horizontal
- Alignment: vertical, horizontal
- Font: family, size, weight, style
- Geometry: x, y, width, height
- Window auto resize
- Sensibility (to overide the value computed automaticaly)
- Debug level
Other features:
- a drag and drop working only inside the application.
- fully working text cut and paste (UTF8 or not).
- simple animation possible.
- the library runs a web server allowing to debug.
- accelerators. If a modifier key is pressed, a list of short-cut with this key is displayed in a bubble tip.
Enhancements:
- Complete rewrite of the kernel API, in order to have :
- The library can now be updated without recompiling external code

DGS Search was created to provide an easy to install search utility capable of handling filesystem and database searches on UNIX and Windows based platforms.

DGS Search is aimed at supporting the small to medium sized web site.

pro-search is a crawler for FTP servers, SMB shares, HTTP servers, and DC++ networks.

WWW::Search is a collection of Perl modules which provide an API to WWW search engines like WebCrawler, AltaVista, Hotbot, Lycos and so on. Currently WWW::Search includes back-ends for variations of AltaVista, Lycos, and HotBot.

We include two applications built from this library: AutoSearch (an program to automate tracking of search results over time), and a small demonstration program to drive the library. Back-ends for other search engines and more sophisticated clients are currently under development.

WWW::Search includes AutoSearch, an program to automate web-based searches.

Search::InvertedIndex is a manager for inverted index maps.

SYNOPSIS

use Search::InvertedIndex;

my $database = Search::InvertedIndex::DB::DB_File_SplitHash->new({
-map_name => /www/search-engine/databases/test-maps/test,
-multi => 4,
-file_mode => 0644,
-lock_mode => EX,
-lock_timeout => 30,
-blocking_locks => 0,
-cachesize => 1000000,
-write_through => 0,
-read_write_mode => RDWR;
});

my $inv_map = Search::Inverted->new({ -database => $database });

# Example Update
##########################################################

my $index_data = "Some scalar - complex structure refs are ok";

my $update = Search::InvertedIndex::Update->new({
-group => keywords,
-index => http://www.nihongo.org/,
-data => $index_data,
-keys => {
some => 10,
scalar => 20,
complex => 15,
structure => 15,
refs => 15,
are => 15,
ok => 15,
},
});
my $result = $inv_map->update({ -update => $update });

# Example Query
# -nodes is an anon list of Search::InvertedIndex::Query
# objects (this allows constructing complex booleans by
# nesting).
#
# -leafs is an anon list of Search::InvertedIndex::Query::Leaf
# objects (used for individual search terms).

my $query_leaf1 = Search::InvertedIndex::Query::Leaf->new({
-key => complex,
-group => keywords,
-weight => 1,
});

my $query_leaf2 = Search::InvertedIndex::Query::Leaf->new({
-key => structure,
-group => keywords,
-weight => 1,

-weight => 1,
});

-weight => 1,
-nodes => [],
-leafs => [$query_leaf1,$query_leaf2],
});
my $query2 = Search::InvertedIndex::Query->new({
-logic => or,
-weight => 1,
-nodes => [$query1],
-leafs => [$query_leaf3],

WWW::Search::GoTo is Perl class for searching GoTo.com.

SYNOPSIS

require WWW::Search;
$search = new WWW::Search(GoTo);

This class is an GoTo specialization of WWW::Search. It handles making and interpreting GoTo searches www-GoTo.com.

Nothing special about GoTo: no search options. It is much like Google in that it attempts to returm relavent search results using simple queries.

This class exports no public interface; all interaction should be done through WWW::Search objects.

Curses::UI::Widget is a base class for all widgets.

CLASS HIERARCHY

Curses::UI::Widget - base class

SYNOPSIS

This class is not used directly by somebody who is building an application using Curses::UI. Its a base class that is expanded by the Curses::UI widgets. See WIDGET STRUCTURE below for a basic widget framework.

use Curses::UI::Widget;
my $widget = new Curses::UI::Widget(
-width => 15,
-height => 5,
-border => 1,
);
