pub struct Parser<'a> { /* private fields */ }

Implementations

impl<'a> Parser<'a>

pub fn new(tokens: &'a [Token]) -> Self

pub fn parse(&mut self) -> Program

pub fn parse_word_for_expansion(&mut self) -> Word

Parse a single word for re-expansion of operator arguments.

frost-expand calls this to recursively expand the word of a ${var:-word} / ${var:=word} / ${var:?word} form, where word may itself contain $other, ${nested}, $(cmd), $((expr)) and quoting. Reusing the real word parser keeps a single expansion path.
