Hey all,
I’ve been playing with multi-line string literals recently and was wondering,
are the below cases supported intentionally or did they just fall out of the
implementation?
1) Nested multi-line strings:
let x = """
outer multi-line
\(
"""
inner multiline
"""
)
outer multi-line
"""
print(x)
2) Multi-line strings nested in "single-line" strings:
let x = "outer string \( """
inner multiline
""") outer string"
print(x)
I’ve been looking at still syntax highlighting strings in the invalid states
they pass through while writing or editing them, and trying to keep any changes
to the file’s highlighted ranges as localized as possible. At the moment when
you open an interpolation in an otherwise terminated multi-line string literal
you get one giant unknown token – an unterminated string – from the opening
triple quotes, past the ‘closing’ triple quotes (that we treat as nested
opening quotes), to the end of the file.
It’d be great to be able to bound the unknown token to what were more likely
intended to be closing quotes, so we still produce tokens for (and syntax
highlight) the rest of the file. Of course with nesting you can’t be sure
they’re closing quotes though, so I wanted to check if the nesting support was
intentional.
Thanks!
