A little sad that Dataviewjs doesn't work in frontmatter

[holroy]

During av visit today I had a brilliant idea of adding some inline dataviewjs into the frontmatter of a note, dereferencing some other frontmatter fields, so I went ahead and created the following:

---
cssClass: something, `$= dv.current().css_1`, `$=dv.current().css_2`
css_1: python1
css_2: javascript2
---
cssClass:: `$= dv.current().css_1`, `$=dv.current().css_2`

Then I tried testing this, and seeing if it had the wanted effect. Which it didn't. Bummer...

So I extended the note a little with the following segment:

```dataviewjs

dv.paragraph(dv.current().file.frontmatter)
dv.paragraph(dv.current().css_1)
dv.paragraph(dv.current().css_2)
dv.paragraph(dv.current().cssClass)
```

And when I looked at the reading view, I was both disheartened and little hopeful, but alas it still didn't work as expected as the image below shows:

In the reading view, in the middle, it kind of seems like everything should be OK, if you don't look at the Metadata. But when you look at highlighted line in Developer Tools > Elements, you'll see that the actual class that was added to the main div was the literal inline dataviewjs query. Which then again, when inserted into the reading view, actually got executed before the note is showed in the reading view, so it kind of indicates it should work.

So, not really disappointed, but a little sad that I can't execute inline dataviewJS queries in the frontmatter. I can understand it, but it would have been fun if it had worked. I could have had a lot of fun with queries like that. (Even though it would open a rabbit hole in race conditions as to which part got executed first, like would it be setting the CSS class in the main DOM, or would it be the query, and if the query changed would it be able to actually change the DOM, or ... )

PS! I categorised this as "General", because even though I would love to have this as an idea ( or feature request (or bug(?))), I don't think it's really feasible to get this to work. If you'd like to prove me wrong, feel free, as it would be fun (and useful in some cases) to have this kind of functionality.

Can you look at Metadata Menu?

[holroy]

My specific use case was based upon some select menus utilising the Meta bind plugin, and if I understood it correctly the Metadata menu primarily is adding option to changing the frontmatter from the editor.

When re-reading the introduction of Metadata menu, it does say:

Controls
a Field can be modified or added from several locations:

• autocompletion within the editor mode
• Obsidian and plugins menus : file explorer, note, calendar, context menu of a link, many other plugins not fully tested ...
• dataview table if you have dataview plugin installed

However, I'm not sure how to trigger that through changing the selected option from the Meta bind plugin, if at all possible. Worth some thinkering at some point, though. Meta bind only updates a bind target, aka fields in the frontmatter, so how to proceed from there to trigger some call to Metadata menu using DataviewJS... Hmm... Could possibly be done, but it sounds a little convoluted...

Very interesting. Perhaps you'd have better luck asking the meta bind plugin author.
