Liturgical law specs: meaningful example names

[igneus]

spec/liturgical_law_spec.rb builds specs from code examples contained in the markdown files in liturgical_law/. Example names contain markdown file paths and line numbers.

It would be desirable to

• generate an example group for every markdown heading
• include last encountered paragraph number and few initial words of the paragraph in example name (only for documents with numbered paragraphs).

So e.g. the example L525 would have a name like 36. Dominica a die 2... and be nested in several levels of example groups, the deepest one of them being IV. De tempore Nativitatis
