[ELanguageParser

Description: 本程序要求用户在控制台里输入非终极符,终结符与产生式,然后对用户输入的文法进行分析,得出first集 与follow 集,并打印出预测分析表用户决定是否继续进行句型分析,如继续则给出符号分析栈的实现,从而判断刚输入的句子是否为符合该文法的句子。 该程序遵循LL(1) 文法FIRST(A)的构造:是A的所有可能推导的开头终结符或可能的ε FOLLOW(A)是所有句型中出现在紧接A之后的非终结符或“#” 预测分析程序 构造LL(1)分析表 ⅰ,构造文法中所有元素的FIRST和FOLLOW集合 ⅱ,对文法G的每个产生式A->α执行第三步和第四步 ⅲ,对每个终结符a∈FIRST(α),把A->α加至M[A,a] ⅳ,若ε∈FIRST(α),则对任何b∈FOLLOW(A)把A->α加至M[A,b]中 ⅴ,把所有无定义的M[A,a]标上“出错标志”

[ELanguagegrammatica-1.4.tar

Description: Grammatica is a C# and Java parser generator (compiler compiler). It improves upon simlar tools (like yacc and ANTLR) by creating well-commented and readable source code, by having automatic error recovery and detailed error messages, and by support for testing and debugging grammars without generating source code. It supports LL(k) grammars with an unlimited number of look-ahead tokens.

Description: The Compiler Generator Coco/R Coco/R1 is a compiler generator, which takes an attributed grammar of a source language and generates a scanner and a parser for this language. The scanner works as a deterministic finite automaton. The parser uses recursive descent. LL(1) conflicts can be resolved by a multi-symbol lookahead or by semantic checks. Thus the class of accepted grammars is LL(k) for an arbitrary k. There are versions of Coco/R for Java, C#, C++, Delphi, Modula-2, Oberon and other languages. This manual describes the versions for C# and Java implemented at the-The Compiler Generator Coco/RCoco/R1 is a compiler generator, which takes an attributed grammar of a source languageand generates a scanner and a parser for this language.
