Partial DSL editing + Monaco in other html elements

[jmenzies12]

Hey there!

We've added what we like to call "fancy descriptions" in our DSLs, essentially they allows the user to reference other items in the description and then we evaluate this at runtime to display it appropriately. For example:

item I1: This is a fancy description, {some_other_dsl.O4} would display as something like 'This is a fancy description, O4: Has a fancier description'

However we want to allow users to edit the syntax specifically just for the fancy description from other places. For example a cell in a table editor, or a popup in a diagram editor, complete with content assist, validation etc.

To do this we'd likely need to be able to partially edit a DSL, and integrate the DSL editor (Monaco) into different HTML elements. Is this something Langium supports?

Cheers
Jonathan

hi, am not sure what you mean by partially edit, but when we (jobby job) experimented with "hacky calling setHiddenAreas" (microsoft/monaco-editor#45) on monaco we still were editing the complete document, but monaco simply wont display the hidden parts.

so the question is what are exactly looking for on langium side

Hey @cdietrich,

So by partially edit, I mean what you go on to describe, not displaying the hidden parts. Allowing the user to edit a specific section of the document whilst technically still editing the complete document keeping the validation and content assist intact.

I figured I'd ask here first incase someone had done something similar, it can be harder to get a response from Microsoft. It does look like it's more of a Monaco thing than Langium itself.

It looks like setHiddenAreas may have been deprecated.

Hey @jmenzies12,

have you had seen volar yet? I believe that should fit your requirements nicely.

We had some people try that in the past, see here and here.

Hey @msujew,

I had not heard of volar, I'll take a look at it. Thanks :)
