py-plm

This is a compiler for the PL/M programming language (written in Python). It produces Z80 assembly code as output. There are several components:

• preprocessor,
• comment remover,
• literally expander,
• parser,
• code generator.

All of these are command line tools. The main program plm.py calls each of these in the row and produces Z80 assembly output.

The tests directory has several tests. In order to build them, several tools are used:

• z88dk-z80asm
• zxcc
• zsm4
• plm80c, linkc, locate_c, objhex_c from c-ports of intel80tools available at https://github.com/ogdenpm/c-ports.
• asm80c can also be used to assemble files compatible with the Intel software suite

A program, namely do_tests.py runs the test programs with some example inputs and compares it to the ouput of the Intel PL/M-80 compiler.

The software is still very fresh, so there are a lot of things that are either not implement at all, implemented superficially, or implemented very badly with a lot of bugs.
