Gimp Python in Batch mode

Question

I am trying to execute a Python piece of code in batch mode to edit an existing Gimp file. Getting the following error

batch command experienced an execution error: Error: ( : 1) eval: unbound variable: commmand-line-execution

Here is the code I am using:

---

#!/usr/bin/env python

from gimpfu import *

# the script
def my_tf_cmd_function(fle, fontname, fontsize) :
    image = pdb.gimp_file_load(fle,fle)
    drawable = pdb.gimp_image_get_active_layer(image)
    image.undo_group_start()
    foreground = gimp.get_foreground()  
    gimp.set_foreground(240,240,240)
    textlayer1 = gimp.Layer(image, "Troo", drawable.width, drawable.height, RGBA_IMAGE, 100, NORMAL_MODE)
    image.add_layer(textlayer1, 0)
    pdb.gimp_drawable_fill(textlayer1, 3) # transparent fill
    gimp.set_background(255, 255, 255) 
    gimp.set_foreground(240,240,240)
    floattext = pdb.gimp_text_fontname(image, textlayer1, 200, 100, "T", 1, 1, fontsize, 1, fontname)

    pdb.gimp_floating_sel_anchor(floattext)
    gimp.set_foreground(foreground) 
    image.undo_group_end()
    pdb.gimp_file_save(image,  drawable,  "/home/Downloads/img.xcf",  "/home/Downloads/img.xcf")
    return


# This is the plugin registration function
register(
    "command_line_execution",    
    "My Command Line Attempt Python-Fu",
    "This script does nothing and is extremely good at it",
    "RC",      
    "RC", 
    "May 2013",
    "<Image>/MyScripts/My Command Python-Fu", 
    "*", 
    [
      (PF_STRING, "fle", "GlobPattern", "*.*"),
      (PF_FONT, "fontname", "Foo font", "Arial"),
      (PF_INT, "fontsize", "Foo font size", 18)
    ], 
    [],
    my_tf_cmd_function,
    )

main()

full answer here: solving gimp unbound variable error

So I came across this question when trying to figure out how to run the function in GIMP.

And I found the answer here: IBM developerWorks

So basically you call the function like so:

gimp -i -b '(python-fu-command-line-execution 0 0 0 "*.*" "Arial" 18)' -b '(gimp-quit 0)'

The first 3 zeros is for the 3 default parameters:

• INTERACTIVE MODE OR NOT
• img IMAGE
• draw DRAWABLE

I know your code doesn't really use any of these, but these are required, so... and as for why they must be integers, I have no idea myself. I trial and error and found that INTEGER works for me.

If anyone have a better understanding of what's going on, do enlighten.

Edit:

So I have this problem myself initially... and I found out that the Error: ( : 1) eval: unbound variable: commmand-line-execution error is caused when inserting the batch command through the CLI in Scheme language.

But to check if your function is registered, go to the Procedure Browser (Help > Procedure Browser) and search for your function, (it will something like python-fu-command-line-execution).

If its not there, check out this article on where to place your plugin files to get it registered: wikibooks.

If it is registered, you can try running it in the Console. (Filters > Python Fu > Console), if it runs, you don't have a issue with your code.

But all the same, you should try running the command in the format first, the error is something related to the scheme command given...
