Template:Scripting

Templates are pre-written scripts in a particular scripting language. They can be distributed as any other plugin, and automatically discovered by the Script Editor. Templates thus present an excellent way to demonstrate a particular operation to a wide audience of users.

Available templates are sorted by language under the Templates menu of the Script Editor. The contents of a template will be loaded into the editor window when selected. The script can then be inspected, executed and modified as normal.

Adding A New Template

The Script Editor will automatically search the script-templates directory and register any discovered scripts as templates. For example, a Mavenized project could add a sample script in src/main/resources/script-templates and it would be packaged into the appropriate location of the resultant .jar.

Script language determination is based simply off file extension. So a FFT.rb script would be indexed under the Templates > Ruby menu.

For examples of how the existing templates are structured and distributed, take a look at the core SciJava scripting projects.

Template Best Practices

Above all else, templates should be well documented. Templates are intended to explain specific functionality in a given language, to users who may have limited experience with the language or programming/scripting in general.

Ideally, a template will be focused on an a single objective (e.g. opening an image, calculating a threshold, operating on a directory, etc...).

It is especially helpful to document how the template can be adapted to meet the user's needs.
