simplepreprocessor expands limited set of C preprocessor macros

Project description

simplepreprocessor

Usage

import simplecpreprocessor

There will be one function called preprocess. It can either be called with a file object or something that looks sufficiently like a file object. See unit tests to find out what's enough for a compatible wrapper. Line endings are by default normalized to unix but a parameter can be given to customize this behaviour.

Gotchas

Supported macros: ifdef, ifndef, define, undef, include, else, pragma (only "once")

If using for FFI, you may want to ignore some system headers eg for types

Limitations:

  • Multiline continuations supported but whitespace handling may not be 1:1 with real preprocessors. Trailing whitespace is removed if before comment, indentation from first line is removed
  • Semi-colon handling may not be identical to real preprocessors
