seq method
Returns a parser that accepts the receiver followed by other
. The
resulting parser returns a list of the parse result of the receiver
followed by the parse result of other
. Calling this method on an
existing sequence code does not nest this sequence into a new one, but
instead augments the existing sequence with other
.
For example, the parser letter().seq(digit()).seq(letter())
accepts a
letter followed by a digit and another letter. The parse result of the
input string 'a1b'
is the list ['a', '1', 'b']
.
Implementation
@useResult
Parser<List> seq(Parser other) => this is SequenceParser
? [...children, other].toSequenceParser()
: [this, other].toSequenceParser();
