Some GRASS commands broken

[neteler]

Hi,

some GRASS commands are broken:

r.median base=CEA_cat@CEA_dati cover=CEA_aspect@CEA_dati output=aspect_median

Illegal filename. Character <'> not allowed.
Illegal filename. Character <'> not allowed.
Raster map ['CEA_aspect@CEA_dati'] not found
Illegal filename. Character <'> not allowed.
r.stats: ['CEA_aspect@CEA_dati] not found

Successfully finished

-> unclear why ' is present

---

r.mode base=delete cover=CEA_aspect output=del_aspetto

Illegal filename. Character <'> not allowed.
ERROR: r.stats: ['delete@CEA_dati] not found
Illegal filename. Character <'> not allowed.
Illegal filename. Character <'> not allowed.
ERROR: Raster map ['delete@CEA_dati'] not found

Same thing here.

But r.average with the same syntax works perfectly.

g.manual index

C:/Programmi/Quantum_GIS/grass/scripts/g.manual: ./: is a directory

this indicates that GRASS_HTML_BROWSER is undefined.

Update: Shame on GRASS :-)

Glynn Clements found it:

"r.median invokes r.stats via system(), using a single quote:

    strcpy (command, "r.stats -a '");
    strcat (command, G_fully_qualified_name (basemap, base_mapset));
    strcat (command, ",");
    strcat (command, G_fully_qualified_name (covermap, cover_mapset));
    strcat (command, "'");

/* strcpy (command,"cat /tmp/t"); */
    stats_fd = popen (command, "r");

    sprintf (command, "r.reclass i='%s' o='%s'",
        G_fully_qualified_name (basemap, base_mapset), outmap);

system() uses the platform's shell: /bin/sh on Unix, cmd.exe on
Windows NT/2K/XP, command.com on 95/98/ME. Single quotes won't work
with the Windows shells.

r.average doesn't quote the map names, and uses double quotes around
the output filename:

    sprintf (command, "%s -anC input=%s,%s fs=space > \"%s\"",
        STATS, basemap->answer, covermap->answer, tempfile1);

Using double quotes should suffice so long as the map name doesn't
contain $ or ` (a double quote would also be problematic, but isn't
legal in map names).

Ultimately, we need a Windows implementation of G_spawn_ex(), so that
we can avoid the shell altogether.

I have fixed r.mode, r.median, and r.statistics in GRASS 6.3-CVS to use double quotes which are supported by MS-Windows.

Once QGIS take a new GRASS version, the problem should be cured.

Additionally fixed:

• r.digit
• r.report
• r.transect

It seems that all raster commands are ok now.
