no bullshit code explorer

TL;DR: use ctags for code exploration tasks, more useable than grep and less bullshit than lsp

C syntax is pretty tricky if you want to for example grep a function’s definition. A grep regex is pretty hopeless, a lsp is too heavy, cscope is unmaintained.

#!/usr/bin/bash
#vi: tw=100

ctags -x --kinds-c=+p+x $* \
    | grep -avE "^operator |CONFIG_"  \
    | awk '{print $1"\t"$2"\t"$4":"$3}' \

use it with e.g.

# find function definitions of foo()
$ ct -R src | grep function | grep foo
  1. you need universisal-ctags
  2. you can modify parameters for ctags, and/or use it for other programming languages … checkout man ctags
  3. you can apply more grep reverse matching to the pipeline to exclude unwanted patterns
  4. awk is there is for pretty prints, e.g.
    name    type    file:line
