Text.Pandoc.Templates

Utility functions for working with pandoc templates.

WithDefaultPartials and WithPartials are Monad wrappers. Wrapping these around an instance of PandocMonad gives different instances of TemplateMonad, with different search behaviors when retrieving partials.

To compile a template and limit partial search to pandoc’s data files, use runWithDefaultPartials (compileTemplate ...).

To compile a template and allow partials to be found locally (either on the file system or via HTTP, in the event that the main template has an absolute URL), ue runWithPartials (compileTemplate ...).

getTemplate seeks a template locally, or via HTTP if the template has an absolute URL, falling back to the data files if not found.

getDefaultTemplate

Arguments

:: PandocMonad m

=> Text

Name of writer

-> m Text

Get default template for the specified writer.

compileDefaultTemplate :: PandocMonad m => Text -> m (Template Text)

Get and compile default template for the specified writer. Raise an error on compilation failure.
