Work is in progress on a boost.spirit based SX assembler, written in C++.

The sx assembler consists of 2 parts:

  • frontend; create a syntax tree out of the program text. There is a working spirit grammar without actions (the actual tree building). Open items are:
    • include
    • macros
    • recognizing opcodes that start in the label column (the first column). Currently, a word that starts in the first column will be parsed as a label, never as an opcode.
  • backend; create a list- and hex-file out of the generated parse tree.
