diraccfg 1.0.1

DIRAC cfg files reader

Parser for DIRAC cfg files

diraccfg provides a parser for the configuration files used by DIRAC and its associated projects.

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
