This repository contains a simple C ANSI escape sequence parser. It is intended for use in my own hobby operating system, but can be adapted for different uses.

First, call the function cansid_init(void) which returns a struct cansid_state:

struct cansid_state state = cansid_init();

Then, whenever you receive a char that you want to run through the parser, hand it to cansid_process(struct cansid_state *, char). This returns a struct color_char.

char c = 'x'; // Whatever you want to parse
struct color_char ch = cansid_process(&state, c);

The returned struct indicates how you should print the character. It contains two fields: style, and ascii. The style field is arranged in this format. The ascii field is simply the character which should be printed. If ascii is the NUL byte (i.e 0x00 or \0), then the character should not be outputted to the screen (and therefore the style field should be ignored too).

To add CANSID to your repository, simply place the files cansid.c and cansid.h in the appropriate locations. There are no dependencies and can even be compiled in a freestanding environment.

Running tests can be done with make test.
