About Parser, Lexer and Tokens

In general compilers parse file to produce tokens and using a lexer could check if file is well-formed.

That’s not trivial, so I limit to share some interesting links:

• http://www.hackingwithphp.com/21/5/6/how-to-parse-text-into-tokens, as example to read char by char
• http://www.theendian.com/blog/antlr-4-lexer-parser-and-listener-with-example-grammar/, great and simple theorical lexer!
