ExtPascal is an Object Pascal (Delphi, FreePascal/Lazarus) wrapper/binding for Ext JS, a comprehensive GUI Ajax framework for Rich Internet Application (RIA) development. ExtPascal will wrap Draw2d and CodePress libraries too and future releases. It uses ideas from others Ext JS wrappers: ExtSharp and ExtPHP.

Features

• High performance with native code for Server side programming, no PHP required.
• Uses FastCGI or CGI for Web Server communication.
• Compatible with any Web Server supporting CGI or FastCGI protocols.
• Statefull, keep-alive and multithread server applications.
• Parses Ext JS HTML documentation to Object Pascal code.
• Self-translate Object Pascal code to JavaScript code during execution.
• Coding in full Object Pascal, minimal use of (X)HTML, CSS and JavaScript.
• AJAX programming using Object Pascal.
• Full wrapper to all Ext JS 2.2 classes, singletons and widgets.
• Transparent support for all main web browsers: IE 5+, Firefox 1.5+, Safari 2+ and Opera 9+ on any client side platform!
• Server side multi-platform support through FreePascal 2.2.2+ compiler. Tested on Windows, Linux and Mac OS X.
• Thread Garbage Collector for all Ext JS classes and widgets.
• Slim Services and EventLog support for Windows
• Produces very tiny executables.
• Easy debugging.
• Convert your desktop and client/server applications, made in Delphi/Lazarus, to Web 2.
• Standalone Web Server option on Windows, no Apache/IIS required.
• Delphi style event handler.
• Compatible with Delphi(7..2009) and FreePascal(2.2.2 and 2.3.1).
