I found a template engine that could litterally substitute YAML frontmatter in Obsidian.
It seems easy to configure.
Moreover, we can (and should*) create our own Obsidian plugin in no time,since all the required information are available on the web page with tutorials and a playground.
Nevertheless, I chose to post on the forum in order to
- obtain more information about such engine and,
- possibly hear about a better substitute, or
- read some reviews from those who have previously used that tool
Thanks in advance !!
