So it is useful on describing the syntax of a programming language and implementing the language. However, it is not suitable to use PEG-based parser generators when we separately implement lexical analysis and syntax analysis, since existing PEG-based parsers receive only a string. For example, since a C preprocessor, which is a token-based macro processor, may expand a code fragment that is obtained by expanding macros, a lexer may process same lexemes more than once in macro expansion. When we do not use PEG-based parser for avoiding unnecessary lexical analysis, we need to study and use another lexer and parser. In this presentation we report a packrat parser combinator, implemented in C++, that receives not only strings but also sequences of tokens. The parser described by the combinator can receive as its input a Forward Iterator that returns not only characters but also values of any type. The output of the parser is obtained as a data structure that consists of tuples, variants, optionals and expecteds. We can process the result by describing semantic actions.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌プログラミング（PRO）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2017-12-12","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"10"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:52:11.162266+00:00","id":184909,"links":{}}
