PyDev Setup

PyDev setup notes for OS X 10.8 (Mountain Lion).

Install Eclipse + PyDev

Since PyDev 3 requires Java 7, and Mountain Lion ships with Java 6, I installed older versions of Eclipse & PyDev as follows:

Download newest Eclipse 3.6 from http://wiki.eclipse.org/Older_Versions_Of_Eclipse (Eclipse IDE for Java Developers)
Download newest PyDev 2.X from http://sourceforge.net/projects/pydev/files/pydev/
Unzip Eclipse
Unzip PyDev & move into eclipse/dropins folder

Configuration

Open Eclipse & choose a workspace e.g. ~/Documents/workspace-pydev
Open Prefences and apply the following settings:
- In the section: General -> Editors -> Text Editors
  - Check Insert spaces for tabs
  - Set Print margin column to 100
  - Optional: check Show print margin
  - Optional: check Show line numbers
- In the section: Pydev -> Interpreter - Python
  - Use Auto Config to get the default Python interpreter
- In the section: Pydev -> Editor -> Code Style -> Code Formatter
  - Check Right trim lines?
- In the section: Pydev -> Editor -> Typing
  - Uncheck After '(' indent to its level ...
- In the section: Pydev -> Editor -> Code Analysis
  - Go to tab pep8.py
  - Change Pep8 from "Don't run" to "warning"
- Optional: In the section: Pydev -> Editor
  - Under Appearance color options, choose Comments
  - Change the color to a darker grey (or other color)

Project Setup

Open the Pydev perspective
Choose menu: File -> Import -> Existing projects into workspace
Choose the project directory
When editing, use Format Code and Organize Imports for consistent formatting

TIP: Organize imports should not be used in some cases, especially python files which modify sys.path before import.
