Announcing a new version of the "Make Shortcut" plugin, now called "GimpScripter". It lets you point-and-click create a plugin that calls a sequence of plugins, PDB procedures, or macros. It is a plugin authoring tool.
Gimpscripter is a Gimp plugin written in Python. It generates Python code for a plugin.
The source is at github.com/bootchk/gimpscripter. Installation instruction are in the README file. The source includes many readable documents such as NEWS, TODO, and a user's manual. You can download a tarball or zip there. It is in Python so just install it in the standard Gimp directory for plugins, no compilation necessary.
Gimpscripter is still in development. It usually works, but is incomplete and could be improved.
Take a look if you are interested in scripting Gimp, as a user or as a programmer.
Gimpscripter lets you visually (graphically, point-and-click) implement a sequential recipe, for example "Choose this, set that parameter, choose that, ..". It doesn't have any control flow statements.
It uses a stack model: it hides a prefix of parameters and references them to active objects.
It includes a macro facility and macros for common sequences of operations, and to wrap certain PDB procedures with higher-level parameter type, e.g. PF_BRUSH instead of PF_STRING for a brush.
Some people suggest using a recorder/playback tool to automate Gimp. Scripts from such tools break when the Gimp GUI changes, and the scripts are not easily distributable. Gimpscripter is an alternative.
Gimpscripter does have many weaknesses, some of which can be attributed to lack of support from the PDB. So it could help guide improvements to the PDB (but it might not raise any issues not already known, such as not storing defaults.)
I welcome comments or contributions.
Here is an example use, to make a plugin "Stroke selection with selection":
Choose "Filter/Gimpscripter" to start Gimpscripter.
From the menu pane choose "Edit/Copy".
Choose "Edit/Paste as/New Brush".
Choose "Select/To path".
Enter a name for the plugin, for example "Stroke selection with selection".
Choose the OK button.
Read the summary and choose the OK button.
Open an image and make a selection.
Choose "Shortcuts/Stroke selection with selection".
You should see a mobius like effect.
