I’ve updated the code in the link, so it now has the version that uses elembic. The output is the same, but the style configuration uses elembic and it has more flexibility, although that mostly affects the stanza and line numbers.
Examples and usage questions/suggestions/feature requests are very welcome, that’s a good way to collaborate too.
The alternate approach in How to force line breaks without extra spaces - #12 by nleanba I’ll need to explore - that’s much more flexible about markup. It’s something I rejected early on but maybe not for good reasons (it doesn’t work with multiline code, but the current solution doesn’t either!); let’s see how it works with line numbering.
