Expand tilde for $HOME in grconfig.json about gr

[xapple]

+1 this is really essential to make gr usable and not have to configure it again each time you deploy to a new server.

The worst is that it doesn't even tell you it's a problem so you can search for hours. You just see:

 Skipped  as it does not have a .git subdirectory.

Here is my install script that auto-generates the config file if it can help anyone.

import sh, glob, os
sh.npm('install', '-g', 'git-run')

home = os.environ.get('HOME', '~') + '/'
repo = home + 'repos/'
repos = glob.glob(repo + '*')
path = home + '.grconfig.json'

text =  """
{
  "tags": {
    "all": [
      %s
    ]
  }
}""" % ',\n      '.join(('"%s"' % r for r in repos))
with open(path, 'w') as handle: handle.write(text)
