[back to package description]

hasktags

A tool to generate tag files for vim and emacs

What is it for? A tag file is a index containing key items of your project such as

  • function names
  • module names
  • data declarations
  • ...

So that you can find / jump to them fast.

HOWTO (GENERATING TAG FILES):

Build hasktags (standard cabal build)

Ctag format:

hasktags --ignore-close-implementation --ctags .

Etag format (used by emacs):

hasktags --ignore-close-implementation --etags .

Both formats:

hasktags --ignore-close-implementation .

NB: Generating both tags generates a file called TAGS for Emacs, and one called ctags for Vim.

HOWTO (USING TAG FILES):

ViM

let tags+=tagfile " tags,TAGS is the default setting so probably you don't have to do anything

:tjump foo<tab> or such. See :h tags

NEdit

Load the "tags" file using File/Load Tags File. Use "Ctrl-D" to search for a tag.

XEmacs/Emacs

Load the "TAGS" file using "visit-tags-table" Use "M-." to search for a tag.

jedit

There is a plugin.

Tests

To run the tests, do cd testcases; sh test.sh.

History

In the past this tool was distributed with ghc. I forked and added some features. hasktags itself was moved out of the ghc repository. Then I only verified that my fork finds at least as much tags as the one forked by Igloo.

Future

Things which could be done in the future:

  • make json support optional
  • Marco TĂșlio Pimenta Gontijo proposed replacing json by aeson because it might be faster

Maintainers

See cabal file

Comments about literate haskell (lhs):

Alex no longer supports bird style ">", so should we drop support, too?
