DIRAC cfg files reader

Project description

Parser for DIRAC cfg files

CI PyPI Conda-Forge

diraccfg provides a parser for the configuration files used by DIRAC and its associated projects. It is designed to be usable as either a full Python package or as a standalone file, which can be found in src/diraccfg/cfg.py. The standalone mode allows for this to be used by dirac-install and the pilot scripts without requiring of pip.

Installation

pip install diraccfg

Command line usage

The command line mode of diraccfg primarily serves to convert the configuration into a JSON file which can then be processed using standard tools such as jq.

The following examples are ran using the following configuration file:

DefaultModules = DIRAC
Sources
{
  DIRAC = git://github.com/DIRACGrid/DIRAC.git
}
Releases
{
  integration
  {
    Modules = DIRAC, WebAppDIRAC, VMDIRAC
    Externals = v6r6p8
    DIRACOS = master
  }
  v7r0-pre19
  {
    Modules = DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r5, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1
    DIRACOS = master
  }
  v6r22p2
  {
    Modules = DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r6, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1
    Externals = v6r6p8
    DIRACOS = v1r3
  }
  v6r22p1
  {
    Modules = DIRAC, VMDIRAC:v2r4-pre2, RESTDIRAC:v0r6, COMDIRAC:v0r17, WebAppDIRAC:v4r0p7, OAuthDIRAC:v0r1-pre1
    Externals = v6r6p8
    DIRACOS = v1r3
  }
}

Print as JSON

$ diraccfg as-json example.cfg
