利用MacPorts套件系統來安裝 http://www.macports.org/

sudo port install global

以 trace lftp 的 source code 為例

先抓下tarball

wget -c http://ftp.yars.free.net/pub/source/lftp/lftp-4.1.1.tar.gz

解壓縮

tar zxvf lftp-4.1.1.tar.gz

切換進 source code 的 folder

cd lftp-4.1.1

執行 htags 來產生 source code 的網頁

htags -g -Fnsa

screenshot:

要有搜尋功能請到 HTML 目錄中底下的 cgi-bin 子目錄新增 .htaccess：

Options +ExecCGI
AddHandler cgi-script .cgi

ps. 但我在 Mac OS X 10.6 上找不出怎麼正確讓 CGI-BIN 啟用的方法，所以暫時無法搜尋滿可惜的，有沒有先進知道該怎麼作呢？

安裝

tar zxvf Django-*.tar.gz

cd Django-*.

sudo python setup.py install

開一個新專案

~/djcode$ django-admin.py startproject mysite

~/djcode$ ls -a mysite/
./           ../          __init__.py  manage.py    settings.py  urls.py

__init__.py: 偽裝目錄成package

manage.py: 一個cli的工具，讓妳可以用多種方式和Django專案互動

settings.py: Django專案的設定/組態

urls.py: 此Django專案的URL宣告

執行開發用Server

~/djcode/mysite$ python manage.py runserver
Validating models...
0 errors found
 
Django version 1.1.1, using settings 'mysite.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
[10/Nov/2009 19:55:59] "GET / HTTP/1.1" 200 2053

It worked!

改Port或IP

python manage.py runserver 8080

python manage.py runserver 0.0.0.0:8080

tchinese.py

#!/bin/python
print "Python是個酷玩意"

python tchinese.py
SyntaxError: Non-ASCII character '\xe6' in file tchinese.py on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

錯誤訊息中的連結到這篇文章：PEP 0263 — Defining Python Source Code Encodings
文中提到：

To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as:

# coding=<encoding name>

or (using formats recognized by popular editors)

#!/usr/bin/python
# -*- coding: <encoding name> -*-

or

#!/usr/bin/python
# vim: set fileencoding=<encoding name> :

Example:

#!/bin/python
# -*- coding: utf-8 -*-
print "Python是個酷玩意"

Result:

Python是個酷玩意
