Syntax Parser 《编译原理》课程设计,基于 LR (1) 分析的类 C 语言语法分析器(本项目配套的 词法分析器) 项目简介 本项目为基于 LR (1) 分析的类 C 语言语法分析器,可以实现针对一种类似 C 语言程序的 Token 序列(由 词法分析器 生成)进行语法分析,给出合法判断、出错位置及大致原因。 本项目提供的默认文...
文法及下推自动机:https://github.com/bajdcc/clibparser/blob/master/grammar.txt 经过几天的努力,终于使clibparser全面支持C语言文法,比如: intmain(){usingnamespaceclib;try{cparserp(R"(intmain(){inta,b,c;floatd,e,f;})");autoroot=p.parse();cast::print(root,0,std::cout);}catch(constce...
Support the generation of the IELR(1) parser described in this paper. https://www.sciencedirect.com/science/article/pii/S0167642309001191 This PR will be ready for merging when the following is done. Add tests Currently, I have only created a grammar file and verified its operation in my...
对于某个形式语言,如果存在某个LR(k)文法能够描述这个语言,那么也一定存在一个LR(1)文法去描述这个语言[1] 如果一个语言能够被一个有效的parser一次性地合理解析,那么该语言可以被LR(k)文法描述。并且LR(k)文法总能被机械性地转换为一个LR(1)文法。因此,LR(1)解析方法的能力在理论上足以处理任何合理的语言。

1.2.1 (2022-08-03) Bug fixes Include LRParser.deserialize in the TypeScript declarations. Fix a bug that broke ParserConfig.specializers (requires @lezer/generator 1.1.1). 1.2.0 (2022-07-04) New features External specializers can now be replaced when reconfiguring an LRParser. 1.1.0 (2022...
operation, it’s complicated, and requires knowledge of how C stores data in memory in order to implement. Possibly more importantly, implementing the solution in C takes a lot longer than it might in another language. If there are any mistakes in my code, it just proves my point even ...

LR(1) - what you can parse when you're using a really good commercial bottom-up parser generator like Yacc++. Not seen much in the real world otherwise, because the internal tables tend to get too big. > LALR(1) = Look-Ahead LR(1), but the (1) indicates that it looks >ahead ...
