Introduction

There are many ways to install the requirements for Ninja-IDE to run. Here my aim will be to write a guide as straightforward as possible to get you runing Ninja in a glimpse. Then, I'll give a rough guide for more advanced or curious users than want to perform their own installation their way(for instance, using a virtualenv).

Details

We'll need to install the following:

Mercurial (to checkout and keep track of Ninja repo in Google Code).
Brew (a.k.a. "HomeBrew", an awesome Mac OS X package installer that resembles apt-get a lot)
Qt
PyQt

Install Mercurial

Go to http://mercurial.berkwood.com/
Download and install the latest version of the Mercurial binaries.

Install Brew

With this command, you get Brew installed to /usr/local.

NOTE: DO NOT RUN THIS COMMAND AS ROOT OR USING SUDO, RUN IT AS A COMMON USER!!

       $ ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

HomeBrew project site: http://github.com/mxcl/homebrew

Install XCode

You can get the latest version of XCode from Apple here

Install sip, Qt and PyQt

From a console, run the following commands:

        $ brew install sip
        $ brew install qt
        $ brew install pyqt
        $ easy_install rope
        $ easy_install pygments

Note: Brew downloads the source of the packages and compiles it and as some of the above listed programs are quite big, it is natural for the compilation to take A BUNCH of time.

Check installations: To check the installation details for the packages you install using brew, run a command like this(in this example, for "pyqt" package):

MacBookPro:Cellar matias$ brew info pyqt
pyqt 4.8.3
http://www.riverbankcomputing.co.uk/software/pyqt
Depends on: sip, qt
/usr/local/Cellar/pyqt/4.7.7 (537 files, 19M)
/usr/local/Cellar/pyqt/4.8 (525 files, 19M)

This formula won't function until you amend your PYTHONPATH like so:
    export PYTHONPATH=/usr/local/lib/python:$PYTHONPATH

Checkout Ninja-IDE repository:

        $ hg clone https://ninja-ide.googlecode.com/hg/ ninja-ide

Run Ninja

        $ cd ninja-ide
        $ python ninja.py

Note: If you get this error:

MacBookPro:ninja-ide matias$ python ninja.py 
Traceback (most recent call last):
  File "ninja.py", line 59, in <module>
    ninja_ide.setup_and_run()
  File "/Users/matias/Dev/ninja-ide/ninja_ide/__init__.py", line 40, in setup_and_run

  File "/Users/matias/Dev/ninja-ide/ninja_ide/gui/qt/ide.py", line 6, in <module>
    from PyQt4.QtGui import QMainWindow

add this line to your ~/.profile file to amend your PYTHONPATH:

    export PYTHONPATH=/usr/local/lib/python:$PYTHONPATH
