A ctags file generator for cabal/stack project dependencies.
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/stack project.
You basically do codex update
in your project directory and you'll get a file (codex.tags
by default, or TAGS
when using
emacs format) that you can use in your favorite text editor.
By default the generated tags file will include tags of the current project as well, this functionality can be disabled in your ~/.codex
file.
Codex is published on Hackage (and also mirrored on Stackage and NixOS).
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]]
tags
file from the local hackage cache~/.codex
configuration file for the given tagger~/.codex
configuration file for the given formatNote: 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"
)
I get commitBuffer: invalid argument (invalid character)
when trying to use codex
under Windows, is this a compatibility problem?
It's an general issue with codec (http://jaspervdj.be/hakyll/tutorials/faq.html#hgetcontents-invalid-argument-or-commitbuffer-invalid-argument), which can be solved by running the following commands:
$ /c/Windows/System32/chcp.com 65001
$ codex cache clean
$ rm codex.tags
$ codex update
