Tips for Setting Up Complex CTAGS Search Paths
ctags, linux, vim
Solution
I use:
set tags=~/.tags
set tags+=~/.vim/tags/cpp
set tags+=~/src/git/gitsrc/tags
" and so on...
For generating tags in a particular project's root:
map <C-F12> :!ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .<CR>
I adapted this setup from the C++ code completion vim tip.
Problem
I want to be able to start up vim in an arbitrary subdirectory in my project and have it search up to the project root for the `tags` file, and then to search in an unrelated directory outside the project tree. For example let's say I have the following: ``` ~/projects/foo/bar/baz.c ~/projects/foo/tags ~/some/arbitrary/path/tags ``` I want to open `baz.c` from within the `bar` subdirectory, have it search up to find `foo/tags` and then to search `some/arbitrary/path/tags` if the symbol isn't found in `foo/tags`. Now I know I can do: ``` set tags=./tags,tags; ``` to accomplish the first task. It's apparently the semicolon which tells vim to search up to the root. However neither of the following work: ``` set tags=./tags,tags,~/some/arbitrary/path/tags; set tags=./tags,tags;~/some/arbitrary/path/tags ``` The first one finds only symbols from `~/some/arbitrary/path/tags` while the second one only finds symbols in the tags file at the project root. Anyone know how to do this? I'm on Linux buy the way.
