list-of ( items separator -- parser )

Vocabulary

peg.parsers

Inputs

items	a sequence
separator	a parser

Outputs

parser

a parser

Word description

Returns a parser that returns a list of items separated by the separator parser. Hides the separators and matches a list of one or more items.

Notes

Item AST values equal to ignore are omitted. Hidden items still count toward the minimum number of matches, so the result may be empty.

Use list-of-many to require two or more item matches.

Examples

USING: peg peg.parsers prettyprint ; "a" "a" token "," token list-of parse .
V{ "a" }

USING: peg peg.parsers prettyprint ; "a,a,a,a" "a" token "," token list-of parse .
V{ "a" "a" "a" "a" }
