C#/Java/C++ developer is needed to fix LEX generator

IMPORTANT: KNOWLEDGE OF YACC or BISON or ANTLR ARE REQUIRED. Without them you couldn't complete this task IMPORTANT: this is a strict algorithmic task, you will have to do a lot of math here This is the first part of the https://www.freelancer.com/projects/python/generating-yacc-parser-lexer/. If you complete successfully this part, I can hire you for the second part immediately Given: 1. Matchers, Transitions, States, Backups for Lexer ([login to view URL], [login to view URL]) 2. [login to view URL], which generates .lex definition, based on input Problem: 1. If you run [login to view URL] inside "item_input" or inside "category_input" it will generate .lex definitions 2. Not all rules are recognized (e.g. regexps [0-9]+ or [a-zA-Z]+, negative numbers and floating points) 3. All not recognized rules are marked with _TODO_ in output Task: 1. I will send source code (400 lines of code in c++) of [login to view URL] 2. You have to fix it: there shouldn't be any TODO, all rules have to be marked correctly, to be compatible with YACC/BISON 3. I can give more input data for testing, when those two will be handled. Algorithm must be generic PS: you could rewrite it to your language (C# or Java, python), if you feel comfortable with other language. Main job here is the right ALGORITHM for restoring lexer rules Time box: 1 week
