Scripts do not appear in menu

[MQ95]

Hi, i'm using Gimp 2.10 on ubuntu-based linux.

I'm trying to follow this guide on how to get started with GIMP scripting, but when I save the .py file in the scripts folder or the plug-ins folders nothing happens.

When I restart GIMP I don't see the option to run that script in the menu.
I've also tried downloading other scripts from the internet, put them in the scripts folder and plug-ins folder, and same thing, they don't appear in the menu.


Am I doing something wrong?
This is the script's code, which I copied from the tutorial:

Code:

#!/usr/bin/python

from gimpfu import *

def first_plugin(timg, tdrawable):
 print "Hello, world!"

register(
 "hello_world",
 "Presents a Hello, World! message",
 "Presents a Hello, World! message",
 "Brad Jones",
 "Brad Jones",
 "2017",
 "<Image>/Image/Hello, World!",
 "RGB*, GRAY*",
 [],
 [],
 first_plugin)

main()

It's from 2017, so maybe it's not compatible anymore?

Thanks for the help guys.

Run gimp from a terminal, with verbose mode, you should have some infos about the issue:

Code:

$ gimp --verbose

It seems to work for me:
   

BUT note that python scripts must go into plug-ins AND on Linux they must be marked as executable

Thanks, I managed to get some more info:

This Hello World plugin terminates like this:

Code:

Querying plug-in: '/home/mq/.config/GIMP/2.10/plug-ins/hello_world.py'
gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
Terminating plug-in: '/home/mq/.config/GIMP/2.10/plug-ins/hello_world.py'

The other plugin that I got from the internet does this instead:

Code:

Querying plug-in: '/home/mq/.config/GIMP/2.10/plug-ins/ofn-preset-guides.py'
/usr/bin/env: ‘python’: No such file or directory
gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
Terminating plug-in: '/home/mq/.config/GIMP/2.10/plug-ins/ofn-preset-guides.py'

I'm not very familiar with programming, just the bases, but does this mean that i'm missing some Python package or library?
Does anybody know how to fix it?

Thanks!

First, ensure your script files have "execution" permission:

Code:

$ chmod +x /home/mq/.config/GIMP/2.10/plug-ins/hello_world.py
$ chmod +x /home/mq/.config/GIMP/2.10/plug-ins/ofn-preset-guides.py

Thank you. They already had permission, but I run the commands anyways.

However I get the same results:

Code:

Querying plug-in: '/home/mq/.config/GIMP/2.10/plug-ins/ofn-preset-guides.py'
/usr/bin/env: ‘python’: No such file or directory
gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
Terminating plug-in: '/home/mq/.config/GIMP/2.10/plug-ins/ofn-preset-guides.py'
Querying plug-in: '/home/mq/.config/GIMP/2.10/plug-ins/hello_world.py'
gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error
Terminating plug-in: '/home/mq/.config/GIMP/2.10/plug-ins/hello_world.py'

Intuitively, the cause of the error might be in this line:

Code:

/usr/bin/env: ‘python’: No such file or directory

But I really don't know, I'm no expert.
Do you have any idea?

Again, thank you very much

You need to have

1. Python v2 installed (so that the shebang #! /usr/bin/env python serves its purpose)
2. The Python support installed in Gimp. It used to be a gimp-python package, but since Ubuntu 20.04 it's no longer there.  See here for a fix.

Are the native python plugins provided by gimp working as expected ?
You can try with Export Histogram:
1) run gimp from terminal with --verbose
2) load or import an image
3) menu Colors > Info > Export Histogram...

I see Ofnuts post and confirm.
Using (k)ubuntu 18.04  A bit strange, In a Gimp 2.10 14 the script works OOTB but a Gimp 2.10.22 appimage, different (older) python 2.7 version required a shebang #!/usr/bin/env python As Kevin test work here.

   

@ MQ95 Which version of 'buntu and Gimp 2.10?   If 'buntu 20.04 then python support for Gimp 2.10 is not included.  Look in the Filters menu for the Python-fu entry.
It can be added see:  https://www.gimp-forum.net/Thread-Heal-S...4#pid18354

Alternatives: Use the Gimp flatpak version or Use a Gimp Appimage both include a working python 2.7

Thanks, I tried that but some file links gave me a 404, and some .deb I downloaded couldn't be installed because of dependency issues.

Solved!
I installed the flatpak, and it works correctly now.
It's just a bit of a mess since flatpak isn't supported by default by Kubuntu

I'm on Kubuntu 20.10 by the way (latest version)
That maybe the problem.

Thanks to everyone who helped!
