Any that have a license that would not scare lawyers? I've heard that Oslo may provide this functionality but I'm not sure if it's a build time dependency or also a runtime dependency.

Can anyone clarify what Oslo will provide? I just discovered that F ships with an implementation of yacc and lex. It looks like I will be able to leverage this parser generator for my.

F Samples. The Parsing sample shows how to use the fsyacc and fslex tools to build parsers and lexers for use with F. Appears to have Full source code so it might be possible to "imbed" this directly into your app. It doesn't generate any code directly, it just gives you the DFA and LALR state tables and lets you write your own parser engine to suit your needs.

This way of structuring things doesn't suit everyone or every situation you lose some flexibility since your language must be meet LALR restrictionsso I don't claim this as "the right way", but I liked the separation of parsing algorithm from parse rules and it does mean that any runtime requirements are entirely and easily within your control. Of course you don't have to write your own engine — there are three engines written in C listed on the site for example.

Off-hand I don't know what licenses those engines use, but writing your own engine is frankly trivial if you find the licences unpalatable. GOLD includes documentation that gives a full description of a working algorithm, which is as you'd expect if you understand LALR parsinga simple state machine system. The GOLD program itself is free to use, of course. ANTLR has a runtime component, but you can always take the few classes it uses and include them in your project, at which point you no longer need to reference the runtime assembly.

The Overflow Blog. The Overflow How many jobs can be done at home?A grammar describes the syntax of a programming language, and might be defined in Backus-Naur form BNF. A lexer performs lexical analysis, turning text into tokens.

A parser takes tokens and builds a data structure like an abstract syntax tree AST.

The parser is concerned with context: does the sequence of tokens fit the grammar? A compiler is a combined lexer and parser, built for a specific grammar. The rust code in the.

NET framework. From tamaranga on February 1, Maybe it is not so difficult to allow such capitalized names or describe this limitation in docs. Currently it's just "ParseException: Syntax error", that is not very obvious.

Grammatica is a C and Java parser generator compiler compiler. Also I was trying to get returnTypes working and since there's no examples and it was grouped with the plugin options that went under the tspegjs property, I assumed it would go there.

Parsers are powerful tools, and using ANTLR you could write all sort of parsers, usable from many different languages. In this complete tutorial we are going to: explain the basics: what a parser is, what it can be used for see how to setup ANTLR to be used from Javascript, Python, Java and C discuss […]. There are many news: new targets, better performance, better error handling and several improvements in the development of ANTLR itself.

What is an editor? An editor is, for me, the main tool I use for work. As a Language Engineer I create new languages, I use existing ones and I need different tools to work with them. I would like to be able to hack all of them together, in a customized IDE I can […]. In this post we are going to see how process and transform the information obtained from the parser. Note […].

We can design parsers for new languages, or rewrite parsers for existing languages built in house. On top of parsers we can then help building interpreters, compilers, code generators, documentation generators, or translators code converters to other languages. This site uses cookies.

From a grammar, ANTLR generates a parser that can build parse trees and also generates a listener interface or visitor that makes it easy to respond to the recognition of phrases of interest.

Is there any new mature PHP parser generator now? My searches drove me to the following ones, what do you think about them, any others? I hope I wont have to alter the code as I would like to keep it maintainable.

I've ported Jison, a Bison clone in javascript, to php. It is now part of Jison, but there are a few updates in my fork. The files are here. See the readme in that page, you create a javascript and php parser at the same time that are capable of doing the same or different things.

The other 3 tools are unfamiliar to me as well: I suggest you give them a try.

I need to generate a parser written in PHP to parse a specific grammar not to parse the php language. I now understand the generated code, there is some gaps like unsupported UTF-8 streams but I can manage a Latin 1 conversion before calling the lexer. NicolasThery, it's not just a few missing IO-streams. If memory serves me well, there's no predicates whatsoever, no AST rewriting stuff, no StringTemplate options: compared to properly supported targets, you'd be seriously lacking the larger part of ANTLR's powers!

But, hey, if it's sufficient for you, of course, you should go ahead and give it a try!
