Vim auto-generate ctags

Question

au BufWritePost *.c,*.cpp,*.h !ctags -R

There are a few problems with this:

Answer 1

Auto Tag is a vim plugin that updates existing tag files on save.

I've been using it for years without problems, with the exception that it enforces a maximum size on the tags files. Unless you have a really large set of code all indexed in the same tags file, you shouldn't hit that limit, though.

Note that Auto Tag requires Python support in vim.
