No, that is what I meant.  When I was fixing my own script yesterday
I had to remind myself where non-system scripts lived.  The online
tutorial mentioned ~/.gimp-2.8/scripts which is clearly out of date.

So, it seems there can be any number of possible directories in
~/.config for 2.10 - hopefully they all start 'GIMP' even if they
have a suffix.

Re: [Gimp-user] 'critical error' running luminosity mask script

I'm not the qualified person to respond to this, but: my understanding 
was that App-Image versions use that directory so as not to mess with 
normal installs, which is exactly how I would hope it would work... e.g. 
they're supposed to be 'portable' etc. but need to store their user 
settings somewhere, so... seems reasonable? The CCE uses yet a different 
directory: GIMP-CCE-AppImage...


Or did you mean something else?


You might have that directory, but in my from-source RC2 install my
local scripts are read from

~/.config/GIMP/2.10/scripts/

i.e. GIMP not GIMP-AppImage : something different in how your
version was built ?  I only ask because there will be enough pain
from updating old documentation without multiple variants of the
directory name.

I expect we'll receive that in a few days or weeks, whenever someone

Re: [Gimp-user] 'critical error' running luminosity mask script

[Casey Connor]

Thanks a bunch, Rich -- that script works without error and much faster, 
too, and the masks are in the proper order when done.


But it seems a lot less aggressive; meaning, the "LLL" mask still 
includes much of the image, not just the brightest parts. It's working, 
just doesn't generate as strong a separation as I would need to make it 
useful.


If I have time to poke around at it, I will. And if there are any other 
luminosity mask scripts out there I haven't heard of, I'm all ears! (In 
my secret dreams I hope that a scripter somewhere will make a fancy 
exposure-blending mask-making tool...)


Much obliged,

-c



I do not suppose any of you mailing list guys ever even think of looking at the
gimpusers forum, after all why should you.

but similar question came up a few days ago

http://www.gimpusers.com/mailmsg.php?89758%40forums.gimpusers.com

The Gimp 2.10 appimage is not the best when it come to adding scripts and
plugins, however for once it works.

Just pop the script sg-luminosity-masks29.scm in
~/.config/GIMP-AppImage/2.10/scripts/

looks like this: https://i.imgur.com/5EXnsrb.jpg

Just to follow up -- Michael Natterer has fixed this... turns out the 
script was working fine but the error dialog was unnecessary. Thanks all!

Yeah it was a couple years ago, so it's lost to the fog of memory.
:-) I
think I was updating an old script to be compatible with the more
recent
versions of gimp. I think I just edited the text file directly.
Anyway,
guess I'll dive back in again.

I reported it as a bug instead of just debugging the script
because gimp
popped up a 'critical error' with the stack trace and requested in
the
dialog that I file a bug about it... didn't seem like it was just a
script error, in other words. Sound appropriate?

Thanks,

You said you had edited the script - did you not use the script-fu
console and its included help for that ?  It's some months since I
last had to do that, I'm rusty on the details.

You said you had edited the script - did you not use the script-fu
console and its included help for that ?  It's some months since I
last had to do that, I'm rusty on the details.

And I doubt there will be any quick guides before 2.10 is released.
Things change during development.  For example, one script I used in
2.9.6 gave a lot of warnings - but in RC1 it appeared to work ok
without producing any warnings.

More generally: everyone who uses external scripts will need to test
them to see if they still work.

*WARNING* missing babl fast path(s): "R'G'B'A u8" to "A u8"

I don't find any quick ref guides to updating scripts to work with 
2.10... any pointers to docs online re: what to look out for?

This does not crash, but obviously the script no-longer works.

Welcome to the script-fu console!  And yes, things which worked in
even 2.9.6 no-longer work.  Happy lisping (if such a concept is
possible), or else just "good luck with debugging it".

On 2.10.0-RC2 (with latest babl and gegl), running that script after
starting the gimp from a term gives a series of failed assertions:

gimp: Gimp-Core-CRITICAL: gimp_channel_push_undo: assertion
