    • Can be changed in Preferences -> Keyboard Shortcuts -> extension.generateDocstring

Extension Settings

This extension contributes the following settings:

  • autoDocstring.docstringFormat: Switch between different docstring formats
  • autoDocstring.customTemplatePath: Path to a custom docstring template (absolute or relative to the project root)
  • autoDocstring.generateDocstringOnEnter: Generate the docstring on pressing enter after opening docstring

Custom Docstring Templates

autoDocstring now supports custom templates. The extension uses the mustache.js templating engine. To use a custom template create a .mustache file and specify its path using the customTemplatePath configuration. View the included google docstring template for a usage example. The following tags are available for use in custom templates.
