repr(x)means the input consists of multiple x from zero to infinite times.
rep, repr and rep_sc are similar to each other. For example, all following parsers:
rep(tok(TokenKind.Number))repr(tok(TokenKind.Number))rep_sc(tok(TokenKind.Number))consumes 1 2 3. Both rep and repr return 4 results, but rep_sc only return 1 result:
rep[1, 2, 3][1, 2][1][]
repr[][1][1, 2][1, 2, 3]
rep_sc[1, 2, 3]
Here 1 means a token whose text property is '1'.
