Lexical Error Linguistics
our compiler theory class, we are tasked with creating a simple interpreter for our own designed programming language. I am using jflex and cup as my generators but i'm a bit stuck with what a lexical error is. Also, is it recommended that i use the state feature of jflex? it feels wrong as it seems like the parser is better suited to handling that aspect. and do you recommend any other tools to create the language. lexical error java I'm sorry if i'm impatient but it's due on tuesday. compiler-theory jflex share|improve this question asked Aug 14 '10 at 18:57 cesar 2,404103052 add a comment| 4 Answers 4 active oldest votes up vote 11 down vote accepted A lexical error is any input that can be rejected by the lexer. This generally results from token recognition falling off the end of the rules you've defined. For example (in no particular syntax): [0-9]+ ===> NUMBER token [a-zA-Z] ===> LETTERS token anything else ===> error! If you think about a lexer as a finite state machine that accepts valid input strings, then errors are going to be any input strings that do not result in that finite state machine reaching an accepting state. The rest of your question was rather unclear to me. If you already have some tools you are using, then perhaps you're best to learn how to achieve what you want to achieve using those tools (I have no experience with either of the tools you mentioned). EDIT: Having re-read your question, there's a second part I can answer. It is possible that a language could have no lexical errors - it's the language in which any input string at all is valid input. share|improve this answer edited Aug 15 '10 at 17:34 answered Aug 14 '10 at 23:41 Gian 10.9k3043 add a comment| up vote
