Need support for #bold( )

[EthanPixar]

I am working on Matrix and Vectors, and the code in typst would look like these:

I wonder whether I can add these decrorations myself, so I struggled with the json file and failed.

Hope you can add support for #bold( ) function to make the code more readable!!

Hi !
Implementing bold in special cases is probably possible.
My current system to propagate style might be a problem for more complex situation (like bold(sqrt(2))).

We must match on the bold function, and then add a font-weight style on children.

Yes, I do find cases where the system can not render styles correctly, for example the dash(a) will look like —(a) instead of ā. Currently I just want to add support for bold(), and it would improve readability so much even just by replacing all the bold(a) with just a. I read through the README.md file and tried

{
  "name": "mySymbol",
  "symbol": "|some chars|",
  "category": "operator"
}

but did not work for me. How can I implement this? Great thanks for your reply!

You can't add custom func styles, you can just replace a string, so it needs to be hard coded with other functions.
But instead of abs function for example, which just add bars, bold modify the style of its children.
I will try to implement it in the general case, and just in some special cases (with just a string for example) if it doesn't work.

Unfortunately I don't have the time to do something "cleaner".

Feels free to open another issues for other functions like dash, if you would like to see them implemented. You can even just list them, since I only added the ones I use for my own documents.

Great thanks!! You have really solved my confusion!
