Contributing to casata

Pre-requisites

1. The most recent version of CASA. I get my from https://svn.cv.nrao.edu/casa/linux_distro/
2. The Bazaar version control system tool. It is written in Python so certainly should run on all systems that CASA can! Pre-packaged versions are available for all major operating systems.
3. That’s it? Functioning email address would be good...

Getting the current development version

You can get the current development version with the command:

bzr branch http://www.mrao.cam.ac.uk/~bn204/alma/casata/b/trunk/

Submitting your changes

You should at this point consult some Bazaar documentation! (One potential useful document is http://www.emacswiki.org/emacs/BzrForEmacsDevs).

At the very at least, you should:

1. Let bzr know who you are:

   bzr whoami "your name her"
   

2. After making changes always do:

   bzr status
   

   and:

   bzr diff
   

   to review what you’ve done

3. Once you are satisfied with your changes, commit (and add a descriptive message) using:

   bzr commit
   

4. One you feel ready to share your contribution, send them to everybody using:

   bzr send --mail-to=mrao-casa-devs@lists.cam.ac.uk
   

5. At this point I will try to review your contribution and possibly suggest improvements. Once there is reasonable agreement that about your improvement, I will merge it into the trunk.
