hac

HAC (HAC Ada Compiler) is a small, quickly compiled, open-source Ada compiler, covering a subset of the Ada language. HAC is perhaps the first open-source (albeit partial) Ada compiler fully programmed in Ada itself.

Features:

• Quick: short programming-compilation-run-test cycles.
• Perfect for scripting jobs.
• Compiles Ada sources from any stream - file, internet, editor data, Zip archive, ...
• Compilation leaves zero compilation temp file - all is done in memory!
• Portable, fully programmed in Ada.
• Can be embedded into another software - see the LEA editor - and even exchange data with it - see the src/apps/exchange_native_side.adb demo.
• Free, open-source.
