This tool download and cache the source code of packages in your local hackage,
it can then use this local cache to generate a tags file aggregating the sources of all the dependencies of a given cabal project.
You basically do codex update in your cabal project directory and you'll get a codex.tags file
that you can use in your favorite text editor.
By default the generated codex.tags will include tags of the current project as well, this functionality can be disabled in your ~/codex file.
Codex is published on hackage.
cabal install codex
Note: You might have to install binary dependencies manually as cabal does not support them yet!
By default hasktags will be used, and need to be in the PATH, the tagger command can be fully customized in ~/.codex.
The configuration file is automatically generated with default values when running the tool for the first time.
codex [update] [cache clean] [set tagger [hasktags|ctags]] [set format [vim|emacs|sublime]]
- update: Synchronize the
codex.tagsfile in the current cabal project directory (use --force to discard tags file hash) - cache clean: Remove all
tagsfile from the local hackage cache - set tagger [hasktags|ctags]: Update the
~/.codexconfiguration file for the given tagger - set format [vim|emacs|sublime]: Update the
~/.codexconfiguration file for the given format
Note: codex will browse the parent directory for cabal projects and use them as dependency over hackage when possible.
Put this in your .vimrc:
set tags=tags;/,codex.tags;/
IMPORTANT: You must use a version >= 7.4 (or you'll get E431: Format error in tags file "codex.tags")
