Work with Obsidian vaults in Julia.
An Obsidian vault is just a directory with markdown content. In addition to standard Markdown, the Obsidian app supports wiki-style links for navigating within your vault, and tags beginning with # to add metadata to your notes.
But javascript is not my favorite language, so Obsidian.jl indexes your vault in much the same way as the Obsidian app: you can find incoming and outgoing links to pages, tags occurring on pages or all tags on a page.
In addition, the dataview plugin adds a notation for key-value pairs. By default, Obsidian.jl also indexes these k-v pairs.
To see how it works, see the documentation.
