Generate tags (ctags) or TAGS (etags) file for a bunch of Haskell files.
These files are used by editors (e.g. TAGS by Emacs) to implement jump-to-definition (e.g. M-. in Emacs).
In contrast to hasktags, hs-tags uses the GHC Haskell parser to read the Haskell files and find definition sites.
Example use:
find src -name "*.*hs" | xargs \
hs-tags --cabal Foo.cabal -i dist/build/autogen/cabal_macros.h -e
Creates Emacs TAGS from Haskell files residing in folder src/ of the project as defined in Foo.cabal, using preprocessor definitions from dist/build/autogen/cabal_macros.h.
Command line reference:
hs-tags
--help Show help.
-c[FILE] --ctags[=FILE] Generate ctags (default file=tags)
-e[FILE] --etags[=FILE] Generate etags (default file=TAGS)
-i FILE --include=FILE File to #include
-I DIRECTORY Directory in the include path
--cabal=CABAL FILE Cabal configuration to load additional
language options from
(library options are used)
