[GRASS-user] wxpython fails to open existing grc

[Martin Landa]

Hi,

unfortunately there is no format convector available now, it would be
useful I guess. Please report a wish ticket in Trac for that,
otherwise it will be forgotten;-) To compare grc's formats

grc created by gis.m

Raster aspect at PERMANENT
  _check 1
  opacity 1.0
  map aspect at PERMANENT
  drapemap
  brighten 0
  querytype cat
  rastquery
  rasttype
  bkcolor
  overlay 1
End

workspace file created by wxGUI

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE grc SYSTEM "grass-grc.dtd">
<grc>
    <display>
        <layer type="raster" name="aspect at PERMANENT" checked="1"
opacity="1.000000">
            <task name="d.rast">
                <parameter name="map">
                    <value>aspect at PERMANENT</value>
                </parameter>
            </task>
        </layer>
    </display>
</grc>

yes, the format convector would make sense here. Anyway the format
definitions are completely different in this case,  no backward
compatibility.

This I have fixed in trunk few minutes ago:-) Good point.
