any() function ignoring the first character

[Vaimer9]

The following code doesn't accept the first character in the provided input:

let raw = any()
            .ignore_then(text::ident().padded().repeated())
            .padded()
            .collect::<String>()
            .map(Tokens::Raw);

So if I were to give an input of hello world I would get elloworld (I also have padding issues), can someone guide me in the correct direction to fix both the any() issue and the padding bug

• The first character is ignored by any().ignore_then(...), if you don't want to ignore it, use then
• text::ident().padded().repeated() outputs a list of strings and the padded() ignores the whitespace in between. The collect::<String>() then merges them all into a single string, so: "ello world" -> ["ello", "world"] -> "elloworld"

So the following code results in an error

Here's the error:

[zesterer]

a.then(b) results in an output type that is a tuple of (A, B) (where A and B are the output types of a and b respectively, of course). In your case, the types of A and B are char (because of the any) and Vec<String> (because of the text::ident().padded().repeated()). A tuple cannot be collect-ed into a String, as Rust explains.

I'm not entirely sure what output you're expecting, so I can't really help you any further with this. What output do you want the parser to produce?

[Vaimer9]

The output I want is:
input: foo bar xyz
output: Raw("foo bar xyz")

[zesterer]

Is there a problem with the following?

text::ident()
    .padded()
    .repeated()
    .map(|idents| idents.join(" "))

[Vaimer9]

that works perfectly, don't know why that didn't come into mind 😅
