Incorrect range for SynInterpolatedStringPart.String in extended interpolated string #16418
Description
Consider parsing
$$$"""{{{5}}}"""This will lead to
SynExpr.InterpolatedString(
SynInterpolatedStringPart.String(value = "", range = R("(1,0--1,9)"))
SynInterpolatedStringPart.FillExpr(fillExpr = SynExpr.Const(constant = SynConst.Int32(5), range = R("(1,9--1,10)")), qualifiers = None)
SynInterpolatedStringPart.String(value = "", range = R("(1,12--1,16)"))
)The range of the opening SynInterpolatedStringPart.String covers $$$"""{{{, while the closing SynInterpolatedStringPart.String only covers the range of }""".
Expected behaviour
It should cover }}}""" instead.
Actual behavior
The range only starts from the last }.

@abonie as you worked on this, could you give me a pointer where in the lexer this could be fixed?

Hmm... Somewhere in this section I bet.
Thanks for reporting. Are you planning to look into it @nojaf?

Well, I took a peek at it yesterday. Indeed, around the area you suggested here, but I wasn't able to make a dent.
Would you mind skimming through it maybe?
abonie commentedon Dec 11, 2023
I will give it at least a once-over

So @abonie, did you have any fun with this 😸?
abonie commentedon Dec 19, 2023
Yeah, no luck so far either
