#1555: python-scripts in wingrass64svn
--------------------------------------+-------------------------------------
Reporter: hellik | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 6.4.2
Component: Python | Version: 6.4.2 RCs
Keywords: wingrass, python scripts | Platform: MSWindows Vista
Cpu: x86-32 |
--------------------------------------+-------------------------------------
how is the best way to start/launch additional python-scipts in
standalone wingrass642 (not yet tested in osgeo4w-wingrass)
tested and working examples of python-scipts
http://grass.osgeo.org/wiki/GRASS_AddOns#r.basin
http://grass.osgeo.org/wiki/GRASS_AddOns#r.ipso
http://grass.osgeo.org/wiki/GRASS_AddOns#r.wf
r.basin.py invokes r.ipso.py and r.wf
(also needed for test: all r.stream*-addons:
http://grass.osgeo.org/wiki/GRASS_AddOns#r.stream.angle
http://grass.osgeo.org/wiki/GRASS_AddOns#r.stream.basins
http://grass.osgeo.org/wiki/GRASS_AddOns#r.stream.del
http://grass.osgeo.org/wiki/GRASS_AddOns#r.stream.distance
http://grass.osgeo.org/wiki/GRASS_AddOns#r.stream.extract
http://grass.osgeo.org/wiki/GRASS_AddOns#r.stream.order
http://grass.osgeo.org/wiki/GRASS_AddOns#r.stream.pos
http://grass.osgeo.org/wiki/GRASS_AddOns#r.stream.stats)
all case studies with a self compiled wingrass64svn (newly based on
python272)
tested on a WinVista32-box without any installed stock python, only the
wingrass-bundled.
working example in the nc-sample-dataset (sqlite as vector-db-backend
needed):
{{{
g.region -a rast=elevation at PERMANENT
r.basin --verbose map=elevation at PERMANENT prefix=a easting=637515
northing=224615 threshold=50
}}}
----
'''case study (1)'''
r.basin.py,r.ipso.py,r.wf.py manually added in C:\Program Files\GRASS
6.4.2svn\scripts
r.basin.bat,r.ipso.bat,r.wf.bat manually added in C:\Program Files\GRASS
6.4.2svn\bin
the content of the bat-files:
{{{
@"%GRASS_PYTHON%" "%GISBASE%/scripts/r.basin.py" %*
@"%GRASS_PYTHON%" "%GISBASE%/scripts/r.ipso.py" %*
@"%GRASS_PYTHON%" "%GISBASE%/scripts/r.wf.py" %*
}}}
it's needed to change in r.basin.py
from
{{{
grass.message( "##################################" )
grass.run_command('r.wf.py', map = r_distance,
image = prefix)
grass.message( "##################################" )
# Ipsographic curve
grass.message( "##################################" )
grass.run_command('r.ipso.py', map = 'r_elevation_crop',
image = prefix,
flags = 'ab')
}}}
to
{{{
grass.message( "##################################" )
grass.run_command('r.wf', map = r_distance,
image = prefix)
grass.message( "##################################" )
# Ipsographic curve
grass.message( "##################################" )
grass.run_command('r.ipso', map = 'r_elevation_crop',
image = prefix,
flags = 'ab')
}}}
''(1)a'' => following command in the wxgui-command-line is working
{{{
r.basin --verbose map=elevation at PERMANENT prefix=a easting=637515
northing=224615 threshold=50
ABSCHNITT 1a (von 4): Initiiere den Speicher.
ABSCHNITT 1b (of 4): Ermittle den Fluß aus der Karte heraus.
[...]
Bifurcation Ratio (Horton) : 3.5606
Length Ratio (Horton) : 2.3439
Area ratio (Horton) : 3.3353
Slope ratio (Horton): 1.3381
##################################
Done!
}}}
''(1)b'' => only r.basin in the wxgui-command-line, r.basin-wxgui is
starting, but by starting r.basin from his r.basin-wxgui,
it's interpreted as
r.basin.py map=elevation at PERMANENT prefix=b easting=637515 northing=224615
threshold=50
and there is following error:
r.basin.py map=elevation at PERMANENT prefix=b easting=637515 northing=224615
threshold=50
C:\Program Files\GRASS 6.4.2svn\extrabin\python.exe: can't
open file 'r.basin.py': [Errno 2] No such file or directory
----
'''case study (2)'''
r.basin.py, r.ipso.py, r.wf.py are in i.e. c:\grassscripts
File -> Launch script: c:\grassscripts\r.basin.py
=> r.basin-wxgui is starting, but by starting r.basin from his r.basin-
wxgui, again the same error like above:
r.basin.py map=elevation at PERMANENT prefix=a easting=637515 northing=224615
threshold=50
C:\Program Files\GRASS 6.4.2svn\extrabin\python.exe: can't
open file 'r.basin.py': [Errno 2] No such file or directory
----
'''case study (3)'''

{{{

r.basin.py.bat
r.ipso.py.bat
r.wf.py.bat
}}}
the content of the bat-files:
{{{
@"%GRASS_SH%" "%GISBASE%/scripts/r.basin.py" %*
@"%GRASS_SH%" "%GISBASE%/scripts/r.ipso.py" %*
@"%GRASS_SH%" "%GISBASE%/scripts/r.wf.py" %*
}}}
''(3)a'' => r.basin in the wxgui-command-line, a window pops up because
.py is an ankown extension and
it's asked how to open
''(3)b'' => r.basin.py in the wxgui-command-line, again following error:
C:\Program Files\GRASS 6.4.2svn\extrabin\python.exe: can't
open file 'r.basin.py': [Errno 2] No such file or directory
----
any ideas how the situation for python-script in wingrass642 can be
improved?
so it seems the corresponding wrapper-bat-files should at least contain
"%GRASS_PYTHON%" instead of "%GRASS_SH%"
