What is WebClaire ?

WebClaire is a portable (unixes, Win32) programming framework based on the XL Claire language. XL Claire is a clone of the Claire 3 language which is a high-level functional object-oriented language originally aimed at solving complex problem (see Claire 3 description and the Papers page). The XL CLAIRE language with the WebClaire framework is a more general purpose language while being fully compliant with the original Claire 3 language, either used as a scripting language or as a dynamic web application framework. Claire is written in C++ and comes with an interpreter and a compiler that generates efficient C++.

Key aspects

Inherited from Claire 3 :

• automatic garbage collection
• rules processing capabilities
• rich type system including type intervals and second-order types (with static/dynamic typing)
• parametric classes and methods
• propagation rules based on events
• dynamic versioning that supports easy exploration of search spaces
• set-based programming with an intuitive syntax
• simple-minded object-oriented programming
• truly polymorphic and parametric functional programming
• an entity-relation approach with explicit relations, inverses and unknown values

Starting with XL Claire :

• extended Kernel API
• simpler system integration, compiler interface and module sharing process
• extensible IO architecture with embedded filtering support
• support for arbitrary long strings
• automatic support of memory congestion
• new printing syntax using tag notation ( ?>...<? )
• extensible command line handling, each new module may provide its own option set
• serialization of entities for IPC and session data
• user documentation generation from code comments
• GDB like debugger for both interpreted and compiled code
• parametric regular expression like engine (scanf)

Starting with Web Claire :

• Apache 2.0 bridge (through the apache module mod_wcl)
• HTTP/CGI handling (Http/Wcl modules)
• session support (Wcl module)
• Web debugger providing on page report and backtrace of unhandled exception (Wcl module)
• localization (Locale module)
• DBMS abstraction layer which prevent to write any SQL request (Dbo/Db modules and driver modules)
• XML and SOAP support (Sax/Soap modules)
• on the fly mail generation (Mail module)
• Pdf framework to read and write PDF documents (HTML/CSS convertor, attachements, digital signature) (Pdf module)
