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.

Codex is published on hackage.

cabal install codex

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]]

• update: Synchronize the codex.tags file in the current cabal project directory (use --force to discard tags file hash)
• cache clean: Remove all tags file from the local hackage cache
• set tagger [hasktags|ctags]: Update the ~/.codex configuration file for the given tagger

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")
