[GRASS-user] Checking if a raster is in current MAPSET

GRASS GRASS user

Greetings

I have a Py script where I do some processing. But, I want to limit it to the files that are available in my current mapset. How can I do this? I mean, I just to evaluate if the input is in the current/active MAPSET?

Thanks

Best regards
Monica

grass.script.find_file() is a wrapper for g.findfile. Either check the
returned mapset or use the mapset= argument. You can use
grass.script.gisenv() to determine the current mapset.

Hello Glynn

Hum it sounds interesting. How can I parameterize it? I mean, what is the order of the parameters?

About the current mapset I’m already using it thanks :slight_smile:

PS- Where can I find a list of avaliable functions in grass.python?

    Help on function find_file in module grass.script.core:
    
    find_file(name, element='cell', mapset=None)
        !Returns the output from running g.findfile as a
        dictionary. Example:
        
        \code
        >>> result = grass.find_file('fields', element = 'vector')
        >>> print result['fullname']
        fields@PERMANENT
        >>> print result['file']
        /opt/grass-data/spearfish60/PERMANENT/vector/fields
        \endcode
        
        @param name file name
        @param element element type (default 'cell')
        @param mapset mapset name (default all mapsets in search path)
        
        @return parsed output of g.findfile

About the current mapset I'm already using it thanks :slight_smile:

Although reading the .py files in a text editor may be simpler.
