Below is the full text to src/drawing.c from NetHack 3.4.3. To link to a particular line, write [[drawing.c#line123]], for example. This file defines several graphics sets; a basic one that Nethack calls ASCII; IBM, DEC, MAC, and two special sets for the rogue level, one if you are using the IBM set and one if you aren't. It also defines functions for swapping these graphics sets in.

This is an artifact of the fact that stalkers used to be represented by "I" until they were moved under "E".

This function modifies the showsyms array. graph_chars is a pointer to an array of symbols that are meant to replace symbols in showsyms. This function is used by switch_graphics to swap in the DEC, IBM, MAC, and ASCII graphic sets defined above. For any entry in graph_chars which is 0, use the default symbol.

Swap in one of the predefined graphic sets ASCII, IBM, DEC, or MAC. Note that this function, unlike assign_rogue_graphics below does NOT record the current graphics set. So if you are using a custom graphics set defined by GRAPHICS in the options then this function will overwrite it (this function is called if you toggle the DECgraphics or IBMgraphics options in game).
