Generate ctags from eggs for development.
Project description
z3c.recipe.tag
Introduction
This recipe generates a TAGS database file that can be used with a number of different editors to quickly lookup class and function definitions in your package’s source files and egg dependencies.
Dependencies
Before running a tags enabled buildout, you must install the appropriate command line tag generation tools: exuberant-ctags and id-utils. In Ubuntu, you can install these with apt-get:
$ sudo apt-get install exuberant-ctags id-utils
On a Mac, download and install port from http://www.macports.org/ and then install ctags and idutils in this way:
$ sudo port install ctags idutils
How to use this recipe
With Buildout
Suppose you have an egg called MyApplication. To use this recipe with buildout, you would add the following to the buildout.cfg file:
[tags] recipe = z3c.recipe.tag:tags eggs = MyApplication
This produces a script file in the bin/ directory which you can then run like this:
$ ./bin/tags
By default, this script produces three files in the directory from which you ran the script:
a ctags file called TAGS for use by emacs,
a ctags file called tags for use by vi, and
an idutils file called ID for use by either.
You can then use these file in your editor of choice.
Optionally, you can select which files to build. The following is the output of ./bin/tags --help:
usage: build_tags [options]
options:
-h, --help show this help message and exit
-l LANGUAGES, --languages=LANGUAGES
ctags comma-separated list of languages. defaults to
``-JavaScript``
-e, --ctags-emacs flag to build emacs ctags ``TAGS`` file
-v, --ctags-vi flag to build vi ctags ``tags`` file
-b, --ctags-bbedit flag to build bbedit ctags ``tags`` file
-i, --idutils flag to build idutils ``ID`` file
With Paver
If you are using Paver and already have z3c.recipe.tag installed, then all you have to do is add this line to your pavement.py file:
import z3c.recipe.tag
And then run the z3c.recipe.tag.tags task from the command line:
$ paver z3c.recipe.tag.tags
Additional Resources
For additional information on using tags tables with different editors see the following websites:
Emacs: http://www.gnu.org/software/emacs/manual/html_node/emacs/Tags.html
to jump to the location of a tag, type M-x find-tag and the name of the tag. Or use M-. to jump to the tag matching the token the cursor is currently on. The first time you do this, you will be prompted for the location of the TAGS file.

CHANGES
0.4.1 (2012-01-11)
Skip nonexistent sys.path directories to avoid ctags warnings.
0.4.0 (2010-08-29)
Support new script features from zc.buildout 1.5 and higher. This version requires zc.buildout 1.5 or higher.
Also index Mako and HTML files with id-utils.
0.3.0 (2009-08-16)
Add support for using this recipe as a paver task.
Also index Javascript, CSS and ReStructuredText files with id-utils.
Define a default entry point for zc.buildout, so you can simply say:
[ctags] recipe = z3c.recipe.tag
0.2.0 (2008-08-28)
Allow command-line choices for what files to build, and what languages ctags should parse. (Note that the default behavior of running ./bin/tags is the same as previous releases.)
Support the Mac OS X packaging system “macports” (exuberant ctags is ctags-exuberant in Ubuntu and ctags in macports).
Support creating BBEdit-style ctags files.
Small changes for development (use bootstrap external, set svn:ignore)
