[GRASS-user] running grass commands in external IDE

GRASS GRASS user

I’m trying to access Grass functionality via Python outside the shell in the GUI.

import sys, os

gisbase = os.environ[‘GISBASE’] = r’C:\Program Files (x86)\GRASS GIS 7.0.svn’
gisdbase = r’E:\Sample’

location = ‘duplin_phons’
mapset = ‘PERMANENT’

sys.path.append(os.path.join(os.environ[‘GISBASE’], “etc”, “python”, “grass”, “script”))

import grass.script as grass
import grass.script.setup as gsetup

However when I try to run any grass commands I get

ImportError: No module named grass.script

When I’m in the shell and run

import grass.script as grass

print grass.file

I’m returned:
C:\Program Files (x86)\GRASS GIS 7.0.svn\etc\python\grass\script_init_.py

Am I missing a connection somewhere?

Thanks for suggestions

Please check this page:

It may give you some hints (I have no Windows here to test your code).

Since the import is `import grass` or similar, you have to add the
directory containing `grass` directory, i.e.:

sys.path.append(os.path.join(os.environ['GISBASE'], "etc", "python"))

By the way, my personal opinion is that

import grass.script as grass

is a bad practice and should be avoided in a new code, the alternative is
not standardized but

import grass.script as gscript

should do.

What's the reason for that ?
