Alien::GvaScript - Gva extension to the prototype javascript framework


  use Alien::GvaScript;
  $path    = Alien::GvaScript->path();
  Alien::GvaScript->install( $my_destination_directory );


GvaScript (pronounce "gee-vascript") is a javascript framework born in Geneva, Switzerland (GVA is the IATA code for Geneva Cointrin International Airport).

It is built on top of the prototype object-oriented javascript framework ( and offers a number of extensions and widgets, such as keymap handling, application-specific events, autocompletion on input field, tree navigation, and forms with autofocus and repeated sections. These functionalities are described in separate documentation pages (see Alien::GvaScript::Intro).

GvaScript is distributed using Perl tools, but the actual content of the library is pure javascript; hence its location in the Alien namespace (see the Alien manifesto).

GvaScript runtime library does not need Perl; you can integrate it in any other Web programming framework. Perl is only needed for developers who want to modify GvaScript sources and recreate a distribution package.


With usual Perl CPAN tools

Install Alien::GvaScript just as any other CPAN module. Then you can write

  perl -MAlien::GvaScript -e "Alien::GvaScript->install('/my/web/directory')"

to copy the dthml files to your Web server.

Without Perl tools

Unzip and untar this distribution, then grab the files in lib/Alien/GvaScript/lib subdirectory and copy them to your Web server.

Note about the documentation

The documentation sources are written in Perl's "POD" format. An HTML version is automatically generated and included in this distribution, under the lib/Alien/GvaScript/html directory; this documentation uses GvaScript's treeNavigator widget for easier browsing.

If this distribution is installed as a CPAN module, then another HTML version will probably be generated automatically by your CPAN tool (but without the treeNavigator widget).
