Source Mapper

From EDM2
Jump to: navigation, search

A multi-platform program that takes C source code and creates a human readable text map out of it, it can work with single files or whole projects. This is primarily useful for initial evaluation of a program structure if you are taking over or joining a C project from anyone else or revisiting code you wrote years earlier but can also be useful as a documentation or teaching/learning tool.

Out of the box the software supports OS/2, Windows and DOS but has in the past also been available in versions for Linux and other UNIX like systems and should be portable to those systems with a minimum amount of fuzz.

The output text map divides the sources into sections that are folded in C style comments, including:

  • Total information and statistics
  • Function register (Sorted list of all functions)
  • List of function calls
  • Identifier list
  • Hierarcial list of calling sequences
  • Source lines map
