Handlebars Support

Several fields in hermit.toml support Handlebars syntax for templating. This allows you to dynamically insert values into your configuration.

With Handlebars, you can access contextual information:

• dir
  • this - The directory of the current hermit.toml file
  • hermit - The location of the .hermitgrab directory
  • home - The home of the user
  • xdg_config - The directory of XDG_CONFIG_HOME or its default
  • xdg_data - The directory of XDG_DATA_HOME or its default
  • xdg_state - The directory of XDG_STATE_HOME or its default
• var - In an install action the variables as specified in the hermit.toml
  • name - The name of the install action
• tag - The values of the detected tags as specified in tags
  • arch for example might be aarch64

The helper function snippet allows you to reference the contents of a defined snippet.
