I am making a plug in in Python for GIMP on Windows. This page suggests running it from the shell or looking at ~/.xsession-errors. Neither work. I am able to run it from the cmd shell as:
gimp-2.8.exe -c --verbose
From here. This causes the output from
pdb.gimp_message(...) to go to a terminal, but only works when everything is running as expected. I get no output on crashes. I tried print statements, they go nowhere. This is a similar problem.
Running it from Python-Fu console gets me nowhere. I need to comment out
import gimpfu as it raises errors and I don't get GTK working. Even if the plugin registers and shows on the menu, when there is some error I don't know where to look for hints.
1- can i refresh a plugin without restarting gimp ? (so at least my slow-morph will be faster )
You must restart GIMP when you add a script or change register(). No need to restart when changing other parts of the script -- it runs as a separate process and will be re-read from disk each time.

2- can i run plug-ins from the python-fu shell. (as opposed to just importing them to make sure they parse.)
Yes, you can access to your registered plug-in in
python-fu console as:
And can call it like:
>>> pdb.name_of_registerd_plug-in(img, arg1, arg2, ...)
python-fu dialog console, you can click to
Browse .. option and find your registered plug-in,
and then click
Apply , to import it to

3- is there an error-log i am missing, or something to that effect?
To log, you can define a function like this:
And use it in your code, whenever you want.
To see log of that, in
gimp program, open
Error Console from
Dockable Dialogs in
Windows menu, otherwise a message box will be pop up on every time you make a log.
Also you can redirect
stdout to a file,:
sys.stderr = open('er.txt', 'a')
sys.stdout = open('log.txt', 'a')
When you do that, all of
exceptions will go to
err.txt and all of print out will be go to
Note that open file with
a option instead of
w to keep log file.
4- is there a way to run gimp on windows from a shell to see output ? (am i better off under cygwin (or virtualbox.. ))?
I got some error for that, but may try again ...
5- i haven't yet looked up how to connect winpdb to an existing process. how would i go about connecting it to a python process that runs inside gimp?
Gimp has own python interpreter, and may you want to install
winpdb to your default python interpreter or to gimp python interpreter.
If you install
winpdb to your default python interpreter, then you need to copy
rpdb2.py installed file to
..\Lib\site-packages of gimp python interpreter path.
After that you should be able to import
pdb2 module from
Python-Fu console of gimp:
GIMP 2.8.10 Python Console
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)]
>>> import rpdb2
Now in your plug-in code, for example in your main function add following code:
import rpdb2 # may be included out side of function.
rpdb2.start_embedded_debugger("pass") # a password that will asked by winpdb
Next, go to gimp and run your python plug-in, when you run your plug-in, it will run and then wait when reach to above code.
Now to open
Winpdb GUI go to
..\PythonXX\Scripts and run
(Note that when using Winpdb for remote debugging make sure any firewall on the way has TCP port 51000 open. Note that if port 51000 is taken Winpdb will search for an alternative port between 51000 and 51023.)
Winpdb GUI from
File menu select
attach and give
pass as password to it, and then you can see your plug-in script on that list, select it and start your debug step by step.
