g.search.modules to include addons

[Nikos Alexandris]

Currently, the search considers only the module_items.xml file (​https://trac.osgeo.org/grass/browser/grass/trunk/scripts/g.search.modules/g.search.modules.py#L197).

Would it make sense for g.search.modules to search also for installed addons? Perhaps by including the $GRASS_ADDON_BASE/modules.xml or(/and?) $GRASS_ADDON_PATH/modules.xml file, in case this file exists.

[Nikos Alexandris]

No progress, just an idea:

if os.getenv("GRASS_ADDON_BASE"):
      ADDON_BASE = os.getenv("GRASS_ADDON_BASE")
      addons_xml = os.path.join(ADDON_BASE, 'modules.xml')
      addons_xml_file = open(addons_xml, 'r')
      addons_descriptions = etree.parse(addons_xml_file)
      addons_xml.close()

See: ​https://stackoverflow.com/a/14879370/11723. Would it make sense to merge the two xml trees?

Indeed, it would be important to have the addon pages included as well.

Nikos, does your proposed patch work?

dupe of #3624 ?

dupe of #3624 ?

No. #3624 is about listing everything altogether (excluding addons), as in ls *. I was looking for a way to list all core GRASS GIS modules at once. It might be required/useful.

Also, an example for the current ticket #3583:

→ g.search.modules keyword=raster,buffer -ca

r.buffer
    keywords: raster,buffer
    description: Creates a raster map showing buffer zones
                 surrounding cells that contain non-NULL category values.

r.buffer.lowmem
    keywords: raster,buffer
    description: Creates a raster map showing buffer zones
                 surrounding cells that contain non-NULL category values. This
                 is the low-memory alternative to the classic r.buffer
                 module.

r.circle
    keywords: raster,buffer,geometry,circle
    description: Creates a raster map containing concentric rings
                 around a given point.

In my system, I have also installed https://grass.osgeo.org/grass74/manuals/addons/v.rast.bufferstats.html which also features the requested keywords raster and buffer but is, obviously, not reported.

I add all installed addons to the list:https://github.com/GRASS-GIS/grass-ci/pull/11

Metamodules like r.modis, r.sim, i.sentinel (and all i.sentinel.... modules) are not listed cause they do not appear with description and keywords in the xml file.

Thanks, merged in r74379.

Metamodules like r.modis, r.sim, i.sentinel (and all i.sentinel.... modules) are not listed cause they do not appear with description and keywords in the xml file.

Confirmed, this doesn't give any result yet:

g.extension i.sentinel
g.search.modules keyword=sentinel

... added as a bug in #3177.
