Switch between header and implementation files

9 years ago

A tags file must have been previously created with ctags passing --extra=+f.

The dictionary maps the suffix of the current file to a list of candidate suffixes for alternate files.

The snippet below supports C/C++, but you may extend it to other file types: just update the dictionary accordingly.

 nnoremap <leader>a :<c-u>tjump /^<c-r>=expand("%:t:r")<cr>\.\(<c-r>=join(get(
        \ {
        \ 'c':   ['h'],
        \ 'cpp': ['h','hpp'],
        \ 'h':   ['c','cpp'],
        \ 'hpp': ['cpp']
        \ },
        \  expand("%:e"), ['UNKNOWN EXTENSION']), '\\\|')<cr>\)$<cr>
