Module documentation for 0.72.0
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)
hasktags --ctags .
Etag format (used by emacs):
hasktags --etags .
hasktags --both .
NB: Generating both tags generates a file called
TAGS for Emacs, and one called
ctags for Vim.
HOWTO (USING TAG FILES):
let tags+=tagfile " tags,TAGS is the default setting so probably you don't have to do anything
:tjump foo<tab> or such. See
You can use a configuration like this one with Tagbar to produce a tagbar like this:
Enormous thanks to Alexey Radkov for the hierarchical design necessary for this usage.
Load the “tags” file using File/Load Tags File. Use “Ctrl-D” to search for a tag.
Load the “TAGS” file using “visit-tags-table” Use “M-.” to search for a tag.
There is a plugin.
To run the tests, do
cd testcases; sh test.sh.
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.
Things which could be done in the future:
- make json support optional
- Marco Túlio Pimenta Gontijo proposed replacing json by aeson because it might be faster
See cabal file
Comments about literate haskell (lhs):
Alex no longer supports bird style “>”, so should we drop support, too?
