Many example Qore scripts/programs.

Qore test scripts. Use run_tests.sh script to run all the tests.

• only UNIX-like platforms are currently supported (although Windows binaries can be built with mxe, and theoretically qore could be built directly on a Windows host)
• requires POSIX threading support
• requires at least flex 2.5.31 (older distributions have flex 2.5.4, flex 2.5.37 recommended) in order to compile the multithreaded parser; you can get this version at: http://sourceforge.net/projects/flex
• requires pcre headers and libraries for perl5-compatible regex support; POSIX regex support is no longer used
• requires openssl headers and libraries
• requires zlib & bzlib headers and libraries
• requires mpfr (and gmp) for the arbitrary-precision numeric support
• optionally support for XML, Oracle, MySQL, PostgreSQL, Sybase, MS SQL Server, SSH2 and more can be built (see README-MODULES for details)
• XML support has been removed as of Qore 0.8.1+; use the "xml" module instead

Qore was originally designed to facilitate embedding integration logic in a workflow/technical order management system (the system is called Qorus Integration Engine).

The initial requirements for the language were: clean threading model, SMP scalability, efficient resource sharing, safe embedding of logic in autonomous objects with restricted capabilities, good networking and lightweight (ex xml-rpc, json-rpc) web-service and other common protocol support, system stability and memory cleanliness.

However, while qore was originally designed as an embedded application scripting library (and still excels at this task), it has evolved to be a fully-functional standalone language as well.
