I\'m currently trying to write a (very) small interpreter/compiler for a programming language. I have set the syntax for the language, and I now need to write down the grammar for the language. I inte
I have a problem parsing integer &am开发者_高级运维p; hex numbers. I want to parse C++ enums with the following rules:
I am trying to create a grammar that accepts two ranges of integer: intege开发者_如何学Pythonr1 from 1 to 10000
I\'m attempting to eliminate left recursion from a CFG by eliminating indirect recursion then direct recursion as this algorithm shows.
Based on my experience, formal grammars typically express comma-delimited lists in a form similar to this:
Suppose I try to parse a string abc with a Packrat Parser: lazy val abc: PackratParser[AnyRef] = ab ~ \"c\"
my question is ¿What would be the best technology to detect hierarchical or tree patterns? I want to recognise开发者_C百科 parts in a HTML page, for example: user login menu, or navigation menu, or
I need to count the number of classes in correct C# source file. I wrote the following grammar: grammar CSharpClassGrammar;
I\'ve gone right back to basics to try and understand how the parser can match an input line such as \"asdf\", or any other jumble of characters, where there is no rule defined for this.
why do we convert the grammar to chomsky normal form ? Is there a advantage ?开发者_运维问答 For one thing, you can use the CYK algorithm on Chomsky Normal Form grammarsChomsky normal form enables a p
