Yet another tags program. Like hasktags, it uses its own parser rather
than haskell-src or haskell-src-exts, so it's fast. It understands
hsc and literate haskell.
In addition, it will load an existing tags file and merge generated tags.
The intent is to bind it to vim's BufWrite autocommand to automatically
keep the tags file up to date. This only works for files changed by the
editor of course, so there are separate git hooks to update on pulls etc.
With the --fully_qualified flag and a fancy vim function, it can
disambiguate tags based on their qualification, even if it's locally
renamed. So M.x will find A.B.x if you import A.B as M.
To see the configuration examples, you probably have to get the source via
cabal unpack or git clone.
Limitations:
Not using a real haskell parser means there is likely to be dark
corners that don't parse right.
Code has to be indented "properly", so brace and semicolon style with
strange dedents will probably confuse it.
