Convert Obsidian-Markdown Notes to HTML

convert-obsidian-markdown-notes-to-html.sh

#!/bin/bash

: '
Pretty roughly converts a single folder of notes from Obsidian/Zettlr markdown
(markdown + wikilinks) to HTML with pandoc. The real trick here is
re-converting WikiLinks back into something that pandoc will work with.

It does not handle percent-encoding for characters other than spaces for
filenames or headers.

mkdir -p html
find . -maxdepth 1 -name '*.md' -print0 | xargs --null -I{} cp {} html/

# Replace WikiLinks with Markdown links
sed -r -i 's,\[\[([^\[\|]+)\|([^\[]+)\]\],[\2](\1),g' html/*
sed -r -i 's,\[\[([^\[\|]+)\]\],[\1](\1),g' html/*

# Replace spaces in links with %20
sed -r -i ':l s,\]\(([^ )#]+) +,](\1%20,;tl' html/*

# Replace spaces in archors with dashes
sed -r -i ':l s,\]\((.+)#([^ )]+) +,](\1#\2-,;tl' html/*

find html -exec pandoc {} -f markdown -t html -o {} \;
rename .md '' html/*
