Since I am learning masking techniques, I wonder if someone could explain the contradiction of these two scripts.

This web page has a download link of a script from "Download from: Google Drive" at produces a file called "patdavid-luminosity-masks-2.scm"

http://blog.patdavid.net/2013/11/getting-around-in-gimp-luminosity-mas ks.html

This file cannot be used because when copied into .gimp-2.8/scripts/ the script entry is not visible on the pull-down menus of gimp.

Did you set the execute permissions, and do you have the first lines "she-bang" interpreter installed?

On the other hand the older script called "Luminosity_masks.scm" does work from some older web pages and does cause the scripts pull-down menu to appear. When the channels menu is invoked from this script the other masks disappear.

Can someone explain this? Any help would be appreciated.

Thats slang for the #!/bin/bash or #!/bin/python, #!/path/to/whatever as the first line of the file. Its the interpreter that the script is intended to be executed by.

I must confess I am not familiar with the requirements of a ".scm' file, so my advice is to be seasoned as needed. :)

Yes the execute bit is set. I do not know what you mean by the "she-bang" interpreter. Can you explain what that is?

On the other hand the older script called "Luminosity_masks.scm" does work from some older web pages and does cause the scripts pull-down menu to appear. When the channels menu is invoked from this script the other masks disappear.

Compare the first line on the file that works, with the first line of the one that does not. I believe its case sensitive. If you post both lines as a straight copy/paste, perhaps someone with better knowledge that I can illuminate the problem.

I do not know what you mean by "other masks disappear".

Can someone explain this? Any help would be appreciated.

It is a GIMP script file and does not need any permission etc. Are you sure that when you download the file extension is intact? What system are you running this on?

I've added Pat to the cc list so that he can work on this as well. :)

To expand on what Partha already said, make sure that the file you download is a plain text file, and that the extension is actually .scm. You should be able to open the file in any text editor to see the contents (and as Gene already mentioned - check that the file contents are similar to the one that works).

Another option is to follow the link to the Registry on that blog post and to try it with Saul Goodes version of the script. This is actually the one that I recommend, as Saul is far more knowledgeable than I about scripting/Scheme.

Check those things and get back to us. We'll get it sorted out. :)
