Backlink: §2020-05-13-1815 Customizing Zetteldeft
In principle, Zetteldeft works from any mode.
To make it work nicely with a Markdown of Zettelkasten, there are a few things you can do.
First, make sure deft-extensions is set correctly.
If md is the first element on the list, new notes will be Markdown notes.
Zetteldeft uses Deft to create new notes, so using zetteldeft-new-file should now create Markdown files.
(setq deft-extensions '("md" "org" "txt"))In such Zettelkasten links are often wrapped in square brackets.
This can be easily achieved by setting the zetteldeft-link-indicator and zetteldeft-link-suffix.
(setq zetteldeft-link-indicator "[[")
(setq zetteldeft-link-suffix "]]")To make sure that your Markdown notes start with correct title syntax, customize the zetteldeft-title-prefix.
(setq zetteldeft-title-prefix "# ")To highlight links you need to set up font-lock keywords for markdown-mode.
(font-lock-add-keywords 'markdown-mode
`((,zetteldeft-id-regex
. font-lock-warning-face)))Alternatively, if you want to highlight the brackets as well, you need to escape them like so:
(font-lock-add-keywords 'markdown-mode
`((,(concat "\\[\\["
zetteldeft-id-regex
"\\]\\]")
. font-lock-warning-face)))
