[GRASS-user] readline completion under bash

GRASS GRASS user
1

Hi

I'm working on my paper for FOSS4G2008 and was about to say something
about the lack of command completion in GRASS when I remembered seeing
the option "--with-readline" in the configure script. I can't find
anything on readline (besides the configure option) in the html docs
and I'm left wondering how to get this working under bash. Is readline
completion available in the svn source or do I need an add-on?

Thanks

Craig

Ps A search of the ML archives for "readline completion" returned zero hits.

compiled-in readline support is only used with r.mapcalc.

or do I need an add-on?

as above. I don't know if it will work with GRASS 6, maybe a keen user
might like to update it. tab-completion for mapname and column names
would be cool.

Which search engine? using Gmane's search I found 18 in .user and 19 in
..devel, using the website's google search some are found too.

Alas, it seems grass-complete doesn't work:
GRASS 6.3.1svn (msunduzi_lo31):~/GIS/scripts/grass-complete > . bash/Init.sh
Unable to initialize bash completions: bash is too old or too new:
BASH_VERSION= 3.2.25(1)-release (needed = 2.05)

Now Nabble finds two posts (the above two) :slight_smile:

Thanks for the info, I needed to check my facts before announcing that
tapping out long map names in the GRASS console is a pain, especially
when you have to do it three times to combine the rgb bands.

I had contacted the author of Grass completions a few years ago
to see if he was interested in perhaps updating it to a newer
version of Bash:

http://article.gmane.org/gmane.comp.gis.grass.user/13851/match=completion

He showed some interest at the time, but I never heard anything further on it.

I have a little workaround for that: I put the name of the base dataset
in a temporary variable.
for example:

r=demOfMyRegionVersion2beta_20080919
g.region rast=$r
d.rast $r

Not quite command-line completion, but it saves me some typing.

cheers,
