-- Pandoc's wikilinks_title_after_pipe extension does basic hyperlinking
|
|
-- of [[bracketed wiki links]]. This lua filter does the rest, mimicking
|
|
-- Obsidian's wiki linking where possible. It
|
|
-- - replaces spaces with hyphens in the uri path and fragment
|
|
-- - lower-cases the fragment
|
|
-- - adds ".html" to the path when appropriate (preserving any fragment).
|
|
-- This is not needed on hledger.org, but makes links work when rendered locally.
|
|
-- Limitations: unlike Obsidian wikilinks,
|
|
-- - these do not find files across folders - correct path is required
|
|
-- - these are not aware of file existence - targets should exist
