#3311: Mismatch between CLI and GUI for r.colors using external rules file
-------------------------+-------------------------
Reporter: madi | Owner: grass-dev@…
     Type: defect | Status: new
Priority: normal | Milestone: 7.2.1
Component: Raster | Version: svn-trunk
Keywords: r.colors | CPU: Unspecified
Platform: Unspecified |
-------------------------+-------------------------
There is a mismatch between the command line and the GUI of r.colors when
providing an external file for color rules. Via command line the correct
(working) command is:

{{{
r.colors map=map_name rules=rules.file
}}}

but via GUI, browsing the rules.file, it will build the following command:

{{{
r.colors map=map_name file=rules.file
}}}

throwing an error like:

{{{
Usage:
  r.colors [-rwlngae] [map=name[,name,...]] [file=name]
[color=style]
    [raster=name] [raster_3d=name] [rules=name] [--help]
[--verbose]
    [--quiet] [--ui]
Flags:
   -r Remove existing color table
   -w Only write new color table if it does not already
exist
   -l List available rules then exit
   -n Invert colors
   -g Logarithmic scaling
   -a Logarithmic-absolute scaling
   -e Histogram equalization
Parameters:
         map Name of raster map(s)
        file Input file with one map name per line
       color Name of color table
               options:

      raster Raster map from which to copy color table
   raster_3d 3D raster map from which to copy color table
       rules Path to rules file
ERROR: Options <map>, <file> and <-l> are mutually exclusive
ERROR: At least one of the following options is required:

here with the GUI the command expands to:

{{{
r.colors map=myslope@user1 rules=D:\temp\test_c_rule.file
}}}

it works

tested with

taken from the manual:

{{{
file=name
     Input file with one map name per line
     Input map names can be defined in an input file in case a large amount
of maps must be specified. This option is mutual exclusive to the map
option.
}}}

''file'' is on the first r.colors-GUI-tab, rules is on the second r
.colors-GUI-tab.

I would say it works normal. :wink:
