Hi all,
I'm fairly new to GRASS, so I apologise if this is a silly question - but I
couldn't find the answer anywhere in either the User or Developer Wikis. I have
written a (very simple) Python add-on which uses the r.reclass tool. Of course,
to use this tool I need to provide a file with the reclass details in it. I am
currently having issues getting GRASS to find this file when I run the script
and I would like it to do this without hard-coding the script path - ie. by
using relative paths. I have two questions:
1. If I am running this script from somewhere outside of the GRASS scripts
directory (eg. from somewhere in my home directory), how should I write my
script so that it simply uses the reclass file in the same directory as the
script? Currently my script contains the line:
grass.run_command("r.reclass", input = options['input'], output =
options['output'], rules = "./zerotonull.rules")
where zerotonull.rules is the file that contains the declass rules, but this
always gives an error saying it can't find that file.
2. If I want to distribute this script (either just to friends/colleagues or by
adding it to the GRASS add-on repository), how should I set up my Makefile so
that the reclass rules file gets put in the right place, and the script can
then find it?
I hope this is the right place to ask this - if not, please accept my apologies.
Best regards,
Robin
