  • :path-substitutions: - Performs substitutions on the file path.

• image directive now supports the following option:

  • :path-substitutions: - Performs substitutions on the image file path.

Use the :nocontent-substitutions: or :nopath-substitutions: flags on individual literalinclude directives to disable substitutions when the default is enabled.
