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() This uses fast-tags to regenerate tags for the current file on every save, but will only work if you are operating from the root of your project (or wherever you keep your tags). I use ctrlp for navigation so that's never been a problem for me Nathan Merkley On Mon, Apr 1, 2019 at 9:26 AM Vanessa McHale <vanessa.mchale@iohk.io> wrote:
Hi all,
I had been using hasktags for tag generation previously, however, I recently discovered that using GHCi with
cabal new-repl λ:> :ctags
creates a tags file that actually works with preprocessors (e.g. c2hs or alex or happy).
Is there any way to run this semi-automatically?
echo ':ctags' | cabal new-repl
seems to work in the shell, but I'd like a vim integration if possible (also, it's slow).
Cheers, Vanessa McHale
