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
The templates need to be put into a subdirectory corresponding with the correct script language name. So a
FFT.rb script would need to be but into the `script-templates/Ruby/` directory to be available under the
Templates > Ruby menu. This is required so that templates are made available only when the corresponding script language is available.
For examples of how the existing templates are structured and distributed, take a look at the
imagej-legacy project (which maintains the script templates that were previously shipped with Fiji's script editor).
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.
