When I run ctags for a project written in bash, tags for functions are generated, but not for variables.
e.g. if I run ctags --list-kinds=sh
f functions
As compared to if I run the list for the "c" language alot more tag types get included.
Is it possible to generate tags for bash variables? or does anyone know of a custom regex that can added to ~/.ctags to enable this?
based on the prompt from @Cometsong I added wrote the regex expression below and added to my ~/.ctags
--regex-sh=/^[ \t]*(local)?[ \t]*([A-Za-z0-9_-]+)=/\2/v,variable,variables/
So far it seems to be working quite nicely
A regex can be built to find variable declarations like [A-z]…=[A-z0-9]
Another for variable usage to include a \$ in the front
My own yaml-specific .ctags example is:
--regex-c=/^( YAML langdef config )/\1/k,t/
--langdef=yaml
--langmap=yaml:.yml.yaml
--regex-yaml=/^[ \t]*-[ \t]*.*:[ \t]*(.+)/\1/k,tasks/
--languages=+yaml
Modified for bash-isms of course.
--regex-sh=/^.*[ \t]*([A-Za-z][A-Za-z0-9_]*)=[".]*/\1/k,tasks/
--languages=+sh
^ plus needed the ability to capture strings inside quotes on the right side of = e.g. foo="hello world"

added export option to the expression from @the_velour_fog since sometimes the global option can also be set using export
--regex-sh=/^[ \t]*(local|export)?[ \t]*([A-Za-z0-9_-]+)=/\2/v,variable,variables/
