While there is probably a better way, my limited knowledge of vimscript had me write this and it works well enough
function! UpdateHaskellTags() if filereadable("tags") execute "silent !grep -v '" . bufname("%") . "' ./tags > __newtags" execute "silent !rm tags" execute "silent !mv __newtags tags" execute "silent !fast-tags " . bufname("%") endif endfunction
autocmd BufWritePost *.hs :call UpdateHaskellTags() autocmd BufWritePost *.hsc :call UpdateHaskellTags()
If I'm reading it right, this goes to a lot of work to defeat (or reimplement?) the default incremental tagging. Why not just 'execute fast-tags %'? I use a script like "if [[ -r tags ]]; then fast-tags -R; else fast-tags $1; fi" for that first generate, and put 'rm tags' in the merge posthook.
