$ pip install git+


Set the GRASS GIS binary that you want to use with: export GRASSBIN=grass75:

>>> from grass_session import Session
>>> from grass.script import core as gcore
>>> with Session(gisdb="/tmp", location="location",
...              create_opts="EPSG:4326"):
...    print(gcore.parse_command("g.gisenv", flags="s"))
{u'GISDBASE': u"'/tmp/';",
 u'LOCATION_NAME': u"'epsg3035';",
>>> with Session(gisdb="/tmp", location="location", mapset="test",
...              create_opts=""):
...    print(gcore.parse_command("g.gisenv", flags="s"))
{u'GISDBASE': u"'/tmp/';",
 u'LOCATION_NAME': u"'epsg3035';",
 u'MAPSET': u"'test';",}


  1. Clone the repository:

    $ git clone
  2. Make sure that py.test, and tox are installed:

    $ pip install -r requirements-testing.txt
  3. Test locally with py.test:

    $ GRASSBIN=~/.local/bin/grass75 PYTHONPATH="`pwd`:$PYTHONPATH" py.test test/py.test test/
  1. Test against multiple Python environments using tox:

    $ tox
