Change default arrow in Grimp script

[magpie03]

Starting to use Gimp everyday now to put arrows on images. I've installed the arrow.scm fu script, but I have to change the default pariminters every time. Can I change the defaults?
I modified the script found in home/.gimp-2.6/scripts and home/.gimp-2.8/scripts but it dosen't work. There is no arrow script in /usr/share/gimp/2.0/scripts.

The default is:

Length of wings -2.5......I want it set at -12.5
Percentage size of notch of arrow head 75....I want it set at 50
Brush Thickness -25.....I want it set at -100

Part of the orginal script is:
SF-ADJUSTMENT "Length of wings (LoW = AL/X) *" '(-2.5 -100 500 10 1 1 1)
SF-ADJUSTMENT "Angle between arrow and wing in degree" '(25 5 85 5 15 0 0)
SF-TOGGLE "Fill head of arrow?" TRUE
SF-ADJUSTMENT "Percentage size of notch of arrow head\n(only valid if head of arrow is filled)" '(75 0 100 1 10 0 1)
SF-ADJUSTMENT "Brush Thickness* (BS = AL/X)" '(-25 -500 500 1 10 0 1)

After backing up the orginal, I changed it to:
SF-ADJUSTMENT "Length of wings (LoW = AL/X) *" '(-12.5 -100 500 10 1 1 1)
SF-ADJUSTMENT "Angle between arrow and wing in degree" '(25 5 85 5 15 0 0)
SF-TOGGLE "Fill head of arrow?" TRUE
SF-ADJUSTMENT "Percentage size of notch of arrow head\n(only valid if head of arrow is filled)" '(50 0 100 1 10 0 1)
SF-ADJUSTMENT "Brush Thickness* (BS = AL/X)" '(-100 -500 500 1 10 0 1)

This does not work. Can it be done? I've never wrote a script before.

Gimp 2.8.2
Ubuntu 12.10

Many thanks all

I'm more familiar with the python-fu scripts...

It looks like it should work.If you are using GImp 2.8 then the .SCM should indeed be put n ~/.gimp-2.8/scripts.

If you start Gimp from a terminal with the --verbose parameter, you will get startup diagnostic messages. Look for either a syntax error or a message about duplicate script definition.

You can also check "Edit/Preferences" -> Folders -> Scripts to see which folders Gimp searches for scripts.

Many thanks Ofnuts. I beleive the script is a python-fu but I'll try what you suggested. Thanks again

No, if the file ends in .scm it's written in Scheme and is therefore a script-fu. Python-fu scripts are technically plugins(*) and are files ending in .py, marked executable on platforms where it matters (Linux, OSX and other Unixen), and kept in the "plugins" subdirectory.

(*) you can do a lot more with Python than with Scheme
