String interpolation in multi-line strings

[jadarve]

Hi, I'm trying to run a string interpolation in a multiline string as follows see demo:

local my_table = {
	name = "Juan"
}

print(`Hello: {my_table.name}`)
print("----------------------")

local multi_line = [[
Multiline hello: {my_table.name}
Another line...
]]

print(multi_line)

However, Luau does not recognize the {} inside of the multiline as an argument for the interpolation.

Current result:

Hello: Juan
----------------------
Multiline hello: {my_table.name}
Another line...

Expected result:

Hello: Juan
----------------------
Multiline hello: Juan
Another line...

Is there syntax for multi-line string interpolation? I tried:

[[`
multiline
`]]

but it includes the ` inside the string.

`[[
]]`

but throws an error: Error:8: Malformed string; did you forget to finish it?

Does something like this work for you (link)?

I believe the original RFC didn't describe multi-line interpolated strings, so we'd need to write up an RFC for it.

Yes, that syntax works for my case. It just does not look as clean as multi-line strings.

About writing a new RFC, I'm happy to contribute.

Closing this issue in that case—glad that it solves your problem. If you'd like to contribute an RFC, we now house them in a separate repository.
