Hi, I've downloaded the 'ncexternal' data from the grassbook website -
I created a 'ncexternal' mapset folder and copied the files into
there.
Whenever I try the examples that access import or process these files
I get an error message in GRASS. For example on p62
r.in.poly in=newfacility.txt out=new_facility_1m
gives
newfacility.txt: No such file or directory
although the file is there. I have tried adding the folder to the
Windows path, but that doesn't solve it.
I am probably doing something stupid or have missed (or skipped :)
something obvious... I would be grateful for any help.
Many thanks
Peter

Peter - two ideas:
- does it work when you use the GUI (i.e., launch r.in.poly without
parameters)?
- does the path to newfacility.txt contain white space? We are still
hunting down those cases where it fails

Hi Markus,
- yes it works using the GUI (should have thought to try this)
- yes, the path contains whitespaces. Using speech or quote marks
around the full path + filename sorts it. Falls over without. A path
without whitespace works but requires unix style forward slashes.
(I stupidly thought that by creating a mapset and saving the data
into that folder GRASS would be able to find it... didn't think I
would need the full path. Will now move the data to a c:\ncexternal
folder to reduce typing :-)
Many thanks
Peter

ok, good.

I darkly remember that we added some Windows-magic for that
elsewhere but I don't remember how.

It does so on non-Windows and it should "learn" it also on Windows!
I tried:
GRASS 6.4.0svn (nc_spm_08): > r.in.poly in=/tmp/dd\ dd/newfacility.txt
out=new_facility_1m
Writing raster map...
100%
GRASS 6.4.0svn (nc_spm_08): > cd /tmp/dd\ dd/
GRASS 6.4.0svn (nc_spm_08):/tmp/dd dd > r.in.poly in=./newfacility.txt
out=new_facility_1m --o
Writing raster map...
100%
Works. So it may be rather the slash stuff than white space?

Yes, for now - we hope to figure out the problem.
Please consider to open a bug report with these findings.

No, I think it is whitespace... I'm trying to use the 'cmd >' field
in the 'GRASS GIS Layer Manager' (the new wxPython GUI). I guess
this is what a Windows user would try to do :-)
I tried adding a space to the folder name (= 'c:\nc external'),
forward slashes don't help but speech or quote marks do.
(I think the same thing happens with all r.in commands if they are
looking for external files - is this to be expected?)
Using the GRASS Command line utility (DOS shell type interface):
GRASS 6.4.0svn (North-Carolina)> cd c:/nc external
The system cannot find the path specified.
GRASS 6.4.0svn (North-Carolina)> cd c:\nc external
(works ok)
Thanks
Peter

@devs:
Perhaps we need some more G_convert_dirseps_*() magic?
