README

Pylookup stole idea from 'http://furius.ca/haddoc', one of my favorite emacs mode for python documentation lookup. I reimplemented python code and elisp code not just to support new version of python 2.7 but also to extend it for other documentation lookup interfaces with easy. Importantly, pylookup mode is much faster and supports fancy highlighting.

INSTALL

Create database

You can browse python documents from either online or offline. Since I prefer offline, here is an easy step:

 make download

It will download python document, and construct database for you. If you get in any trouble, follow the below steps manually:

1. Download your own version of python document (i.e. http://docs.python.org/archives/python-2.7.2-docs-html.zip)
2. Unzip: 'unzip python-2.7.2-docs-html.zip'
3. Index: './pylookup.py -u python-2.7.1-docs-html'
4. Test : './pylookup.py -l ljust'

(see updateing database section for more options)

Elisp

Here is lisp part for emacs.

• [PATH] parameter depends on your environment (i.e. "~/.emacs.d/pylookup")

;; add pylookup to your loadpath, ex) ~/.emacs.d/pylookup
(setq pylookup-dir "[PATH]")
(add-to-list 'load-path pylookup-dir)

;; load pylookup when compile time
(eval-when-compile (require 'pylookup))

;; set executable file and db file
(setq pylookup-program (concat pylookup-dir "/pylookup.py"))
(setq pylookup-db-file (concat pylookup-dir "/pylookup.db"))

;; set search option if you want
;; (setq pylookup-search-options '("--insensitive" "0" "--desc" "0"))

;; to speedup, just load it on demand
(autoload 'pylookup-lookup "pylookup"
  "Lookup SEARCH-TERM in the Python HTML indexes." t)

(autoload 'pylookup-update "pylookup" 
  "Run pylookup-update and create the database at `pylookup-db-file'." t)

Updating Databases

You can easily accumulate many sources into single database. For example, you can index python and scipy at the same time. Here are the examples:

• Single source ./pylookup.py -u http://docs.python.org
• Multiple sources, remote and local ./pylookup.py -u http://docs.python.org -u ~/doc/python2.7
• Adding local source to existing database (duplicate entries are not checked) ./pylookup.py -a -u ~/doc/python
• Example online documents of python, scipy, numpy, and matplotlib (you can append new indexes into the current db with '-a' option) ./pylookup.py -u http://docs.python.org ./pylookup.py -u http://docs.scipy.org/doc/numpy/genindex.html ./pylookup.py -u http://docs.scipy.org/doc/scipy/reference/genindex.html ./pylookup.py -u http://matplotlib.sourceforge.net/genindex.html

You probably like to type './pylookup.py -h' to see more options.
