Logos incorrectly lexing comma-separated list of numbers

[bigyihsuan]

I have an input [1,2]. My Token enum is as follows (truncated):

#[derive(Logos, Debug, Clone, PartialEq)]
pub enum Token {
    // ignore whitespace
    #[error]
    #[regex(r"[ \t\r\n\f]+", logos::skip)]
    Error,

    // ...

    // simple literals
    #[regex("[0-9]+", |lex| parse_int::parse::<i64>(lex.slice()))]
    IntLit(i64),
    #[regex("[0-9]+.[0-9]+", |lex| parse_int::parse::<f64>(lex.slice()))]
    DecLit(f64),

    // ...

    // symbols
    #[token("[")]
    LeftBracket,
    #[token("]")]
    RightBracket,

    // ...
}

However, it returns an Token::Error, saying that 1,2 isn't a valid token (obviously).

I was expecting something like

LeftBracket IntLit(1) Comma IntLit(2) RightBracket

How can I get Logos to lex [1,2] as the above output? Is this possibly related to #279 (specifically "[settling] on the last correctly matched pattern")?

You need to escape the period in your decimal, it matches every character in regex rules.

You are 100% correct, thank you.
