Parsing expression grammars

ACM SIGPLAN Notices, 2004
For decades we have been using Chomsky's generative system of grammars, particularly context-free grammars (CFGs) and regular expressions (REs), to express the syntax of programming languages and protocols. The power of generative grammars to express ambiguity is crucial to their original purpose of modelling natural languages, but this ...

Towards Typed Semantics for Parsing Expression Grammars

Proceedings of the XXIII Brazilian Symposium on Programming Languages, 2019
We describe the formalization of a type system for parsing expression grammars (PEG) which is equivalent to Ford's original fixpoint-based definition of well-formed PEGs. We use our type system definition to implement a functional big-step semantics for typed PEGs using the Agda programming language.

Some Aspects of Parsing Expression Grammar

Fundamenta Informaticae, 2008
Parsing Expression Grammar (PEG) is a new way to specify syntax, by means of a topdown processwith limited backtracking. It can be directly transcribed into a recursive-descent parser. The parser does not require a separate lexer, and backtracking removes the usual LL(1) constraint. This is convenient for many applications, but there are two problems:

A parsing machine for parsing expression grammars with labeled failures

Proceedings of the 31st Annual ACM Symposium on Applied Computing, 2016
Parsing Expression Grammars (PEGs) are a formalism for specifying the syntax of programming languages which can be viewed as a description of a recursive descent parser for the language it describes. An issue that users of PEG-based parsers face is poor reporting of syntax errors on the part of PEG-based parsers.

Optimization of * operator in Parsing Expression Grammar

2015 IEEE International Conference on Electrical, Computer and Communication Technologies (ICECCT), 2015
Packrat Parsing uses recursive decent parsing technique with memorization so that result will not be recomputed. The main advantage is that it allows the use of unlimited look ahead without constraints on the power and flexibility of backtracking. However, this is achieved at the cost of huge memory size.

Parser Generator for Parsing Expression Grammar

2013
In the field of formal languages apart from context free grammar (CFG) a new approach is developed i.e. Parsing Expression Grammar (PEG). Parsing Expression Grammar (PEG) is a new way to specify recursive-descent parsers with limited backtracking. The use of backtracking lifts the LL(1) restriction usually imposed by top-down parsers.

Applying Classical Concepts to Parsing Expression Grammar

Fundamenta Informaticae, 2009
The paper is an attempt to see how much we can learn about a given Parsing Expression Grammar with the help of classical concepts used in the construction of predictive top-down parsers.

BITES Instead of FIRST for Parsing Expression Grammar

Fundamenta Informaticae, 2011
In an earlier paper, the author adapted to Parsing Expression Grammars (PEGs) the properties FIRST and FOLLOW used in the construction of predictive top-down parsers. The purpose was to obtain warnings for possible “language hiding”. It turned out that FIRST does not work well with lookahead expressions.

An attribute language definition for adaptable parsing expression grammars

Proceedings of the 34th ACM/SIGAPP Symposium on Applied Computing, 2019
Adaptable Parsing Expression Grammars (APEG) are a formal model whose main purpose is to formally describe the syntax of extensible languages and their extension mechanisms. APEG extends Parsing Expression Grammar model with the notion of syntactic attributes, which are values passed through parse tree nodes and used during the parsing process.
