I found the docs for gimp python; now:

1) How to get "print" statments? I started filters->python fu->console but apparently a "print" does not write to the console?

2) How can I refresh the script? So far I restart gimp but that is getting tedious.

3) Is there an online site with hints on how to debug a gimp python script?

For reference, here is the script. It apparently runs but I get no new layer and no progress/console output. I did not expect it to work first
time so now I'd like some pointers on how to debug it.

from gimpfu import *

def mass_text(img) : print "Does this go to console?"

pdb.gimp.progress_init("Mass text insert ...")

font = 'Arial Bold'

pdb.gimp.set_foreground( 1.0, 0.0, 0.0 )

# Create a new text layer (-1 for the layer means create a new layer)
layer = pdb.gimp_text_fontname(img, None, 0, 0, "This is my text", 10,
True, 24, PIXELS, font) img.add_layer(layer, 0)

register( "python_fu_mass_text",
"Mass Text",
"Mass create text layers",
"",
"",
"",
"Mass Text Layer insert...",
"*",
[
],
[],
mass_text, menu="/Tools/MassText")

main()

1. To display information in a Python script you can use something like the following example:

pdb.gimp_message('The times are ' + str(sixteenth_time) + " " + str(eighth_time) + " " + str(quarter_time)+ " " + str(half_time))

("\n" will give you a newline(note the double quotes in this case))

2. If I remember correctly (its a while since I debugged a Python script) you just edit and save the script using a text editor and GIMP will then use the updated version when you next run the script (might be best not to save the script whilst part way through actually running the script). (For Script-Fu you also don't need to restart GIMP just use "Filters/Script-Fu/Refresh Scripts" then wait for a few seconds until the refresh is complete)

It does for me... if you enter the "print" on the console. "Print" from a script started form a menu goes to the standard output, whicn on Linux and OSX, is the terminal from which your invoked Gimp. For Windows, things are a bit more complicated, see here: https://www.gimp-forum.net/Thread-Debugging-python-fu-scripts-in-Windows

2) How can I refresh the script? So far I restart gimp but that is getting tedious.

You don't need to, as long as you don't change the registration data. The code is reloaded from the file on each execution; so your latest chnages to the code will be taken in account.

pdb.gimp.progress_init("Mass text insert ...")

font = 'Arial Bold'

pdb.gimp.set_foreground( 1.0, 0.0, 0.0 )

# Create a new text layer (-1 for the layer means create a new layer) layer = pdb.gimp_text_fontname(img, None, 0, 0, "This is my text", 10,
True, 24, PIXELS, font)
img.add_layer(layer, 0)

register( "python_fu_mass_text",
"Mass Text",
"Mass create text layers",
"",
"",
"",
"Mass Text Layer insert...",
"*",
[
],
[],
mass_text, menu="/Tools/MassText")

main()

Try:
pdb.gimp_context_set_foreground((1.,0,0,0))

Also, the " img.add_layer(layer, 0)" isn't necessary, the layer created in gimp_text_fontname() is added to the image automatically.
