    MinForth

    MinForth

    A minimalistic but complete standard Forth compiler in C

    MinForth V3.4 is a classic Forth system with command-line interface. Development resource requirements are minimal. A source text editor and a C compiler are sufficient. By design no toolchain is required to adapt or rebuild MinForth. A complete rebuild takes only few seconds. Current sources are for Windows and Linux (32-bit or 64-bit). MinForth primitive definitions are written in mixed Forth and C language and are transpiled to pure C code. Main but not exclusive application for the transpiler is to build the MinForth V3.4 high-level Forth compiler. MinForth V3.4 is widely conformant to the Forth-2012 draft standard and passes the usual test suites. Feedback and bug reports are welcome per - Usenet forum https://groups.google.com/forum/#!forum/comp.lang.forth - email to minforth@gmx.net

    WinCMOC (M6809 C Compiler)

    WinCMOC (M6809 C Compiler)

    A C Compiler/Editor for Retro 6809 Machines (Colour Computer/Dragon)

    WinCMOC v0.6 is here! So many new features, I cant remember them all. Please uninstall old versions before installing. This is a port of the CMOC compiler (written by Pierre Sarrazin) to Windows. Currently CMOC does not support linking, so, I've written front end tools which edit CMOC's output so that it can be assembled and linked via LWTOOL's. A simple C editor in included which makes it easy to compile/build and run the xroar emulator.
