add powershell shell support to grass74.py

[pmolzer]

I have added powershell as a supported command shell to grass74.py. I don't have SVN commit access and am not on the dev mailing list. Can I just attach the script to this ticket, or should I request some sort of access to SVN?

[hellik]

could you add a diff of your changes instead of attaching the whole script? Then it would be easier to see and evaluate the changes.

[pmolzer]

I've attached a diff. I could not find grass74.py in the source but there is grass.py, so I've modified that.

In 73814:

add powershell shell support to grass.py (see #3713)

patch provided by pmolzer

[martinl]

Slightly modified patch applied to trunk in r73814. Could you test next (no. 348+) WinGRASS build [1]?

Target set to 7.6.0.

please add some hints/examples in the GRASS wiki how to use windows powershell in winGRASS. otherwise this functionality will be hidden for the broader user base.

+1! This would be highly appreciated by those of us Linux users teaching with command line to windows users.

Note also that you can edit this wiki: ​https://grasswiki.osgeo.org/wiki/GRASS_and_windows_console

Thanks much in advance :)

[pmolzer]

will do. I've requested an account for the wiki and wait for approval. Which of these places is the best to add some info?

​https://grasswiki.osgeo.org/wiki/GRASS_and_windows_console ​https://grasswiki.osgeo.org/wiki/GRASS_and_Shell

I'll put some content on use of the GRASS_SH environment variable. maybe also mention the rather heavy escaping needed to call grass from powershell. For example

v.extract input=$state"_Counties" where=`"COUNTY=`'"$ucnty"`'`" output=$cntyname

[veroandreo]

I think that the GRASS and Windows console wiki is a good start. I'm not aware of ppl using powershell in Linux, but in any case, we could eventually move the content or just put a link "for powershell usage see here..." in the GRASS and shell wiki.

Thanks much!

[pmolzer]

done. also noticed a feature request to add support for the linux subsystem for windows. I gave it a try but its not as simple as it seems.

This seems to be already added in r73814. No remaining issues obvious from comments. Closing as fixed. Please, open a new issue on GitHub if you need to follow up.
