Source tags generator
ctags generates tags files that your editor can use to lookup symbols in the source:
all the functions, structs, global variables, etc.
It can be run:
# Recursively
ctags -R .
# On specific files
ctags source1.c source2.c
Unfortunately, that will include some source that isn’t useful.
Using find can help exclude some files and directories:
find . -name '*.[ch]' ! -path './autosetup/*' ! -path './test/*' ! -path './docs/*' ! -path './pgp*.c' | cut -b3- | xargs ctags
ctags can also extract certain types of information.
This can be useful for analysis of the code.
ctags -R -x --c-kinds=f . > functions.txt
ctags -R -x --c-kinds=gsu . > structs.txt
ctags -R -x --c-kinds=v . > variables.txt
