zs-hi is a primitive code highlighter for terminal. The main purpose is testing and debugging of code parsing, but it can also be used on its own.
The only hard-coded color scheme at the moment is for xterm-256color palette.
zs-hi [options...] [{path|-}]
Not providing path argument is equivalent to specifying - and thus reading
from standard input.
pahole -C key_chunk_t vifm | zs-hi
zs-hi utils.c
Whether the parser is able to handle given sources can be checked like this:
find -name '*.[hc]' -exec zs-hi --dry {} \;
It produces output for files with which it has issues.
