    MPL Bytecode Compiler

    MPL Bytecode Compiler

    Micro Programming Language - A Portable Language for Micro Computers

    NEWS: The MPL language is now completely defined. No more language changes are to be made. The compiler is complete and should be easy to translate to other languages if you so choose. MPL is a small, simple language based on BCPL, B, C and Jesusonic. The compiler and interpreter are written in portable Pascal. I have successfully compiled MPL for CP/M, DOS, Windows, Atari ST, Amiga and the Tandy Colour Computer. MPL is designed to be tiny in every way, while implementing all the important features of BCPL & B. The result is a compiler written in a high level language (PASCAL) which compiles to under 16K (CP/M). The symbol table, language syntax, and bytecode are all optimized for size. I will write a MPL Reference Manual in time. Contact myself if you want to help get that written.

    PAS2PHP

    PAS2PHP

    Transpiles/Converts Pascal to Working PHP Source Code

    PAS2PHP will translate a large subset of Object Pascal to PHP, allowing you to write web applications using Lazarus/FreePascal, and then run the application on a standard HTML/PHP server. Over the last week, a lot of work has gone into PAS2PHP. Most of the major issues are resolved. There are still a number of incompatibilities which are either not fixable, or have simple workarounds. As of v0.5, you should be able to write entire PHP applications in Pascal. The key to coding for PAS2PHP is to understand the limitations of PHP. Read the example code provided, and always check the outputed PHP code to understand how this works. As a guide to what PAS2PHP can achieve... my web site is written in Pascal, and then converted to PHP. (The code is in the source package). PAS2PHP uses the Pascal Parse Tree Classes (PasTree) which comes with FreePascal, and therefore the parsing limits are defined by this library.

    pascal p5c

    fast, portable Pascal compiler using gnu c as intermediate code

    p5c is a fast portable iso standard pascal compiler. It is derived from the pascal p5 compiler and creates gnu c code instead of p-code. This makes it very fast since it uses gcc to generate native code. p5c is multi platform - it is easy to get up and running since you only need gcc to start. Using gcc enables extra tools like a static analyser and code coverage analyser. Execution profiling described in the blog here -> https://sourceforge.net/p/pascal-p5c/blog/2017/07/how-to-use-profiling-to-speed-up-p5c-pascal-programs It extends p5 by adding arbitrary set limits and conformant arrays. The project also contains p5x - pascal with extensions to the standard pascal language (underscores allowed in identifiers, otherwise in case statement, constant expressions, etc)
