AlphaZ system is now designed based on eclipse plug-in projects for better collaboration with CAIRN group in IRISA, France. We currently have two repositories hosting different parts of the system, based on where it was initially developed.

Individual directories (with prefix like fr.irisa.cairn or edu.csu.melange) are individual projects in Eclipse, and it is designed to be checked out from Eclipse as projects.

The gecos SVN has a large number of eclipse projects. The list below are for projects that are used by AlphaZ and PolyhedralIR, and is not exhaustive. Consult MANIFEST.MF in edu.csu.melange.alphaz.mde for complete list of required plug-ins.

The following plug-ins are the minimal plug-ins required from Gecos for using CS editor (the scripting interface). Modifying these plug-ins are necessary for extending the scripting interface, but modification must be done with great care.

Anoymous read only access is available through http. The repository is located at 'http://www.cs.colostate.edu/AlphaZsvn/Development'

For developers in CSU, the following location should be used with your CS login
svn+ssh://svn.cs.colostate.edu/s/chopin/e/proj/AlphaZ/AlphaZ_SVNRepositories/Development/

Anonymous read only access is available for the gecos repository. Follow instructions at
https://gforge.inria.fr/scm/?group_id=510 for Gecos SVN and
https://gforge.inria.fr/scm/?group_id=2888 for CAIRN-public

URLS are (for Anonymous and Developer access):
https://scm.gforge.inria.fr/svn/gecos/trunk
https://scm.gforge.inria.fr/svn/cairn-public/trunk

For developers that seek to develop within PolyhedralIR, write access may be needed.
To acquire write access to the gforge repositories:

• Create a new account at https://gforge.inria.fr/ (upper right corner)
• Once the account is created, log-in and access GeCoS website https://gforge.inria.fr/projects/gecos
• Request to join the group from the link at the bottom of list of developers

You may have some error connecting to the repository through eclipse

• When your connection gets lost while trying to connect:
  • Go to Preferences→Team→SVN and change the SVN interface to SVNKit(Pure Java) and try again.
    • The default SVN interface uses JNI bindings and it may not work depending on the machine. Pure Java version should.

For current version of AlphaZ following features from external providers are required:

• Starting Point: Eclipse 3.7.1 with Modeling Tools installed

  • Xtext Antlr SDK (2.0.0)
• From GeCoS update site, under Gecos core category (http://gecos.gforge.inria.fr/fullupdates/stable/):
  • Gecos Framework Feature (1.0.0)
• Optionally, install SVN support for eclipse to access source codes in the repositories
