Building Zerocalc, part I - rustc lexer and a lexer in rust
In this post, we will focus on tokenization. There are many ways to do tokenization, including using regular expressions or generating tokenizer code with generators such as flex. But what if we check how rustc's parser does it?

How to provide input file for Flex++?
I am using Flex++, which is Flex for C++ and I am having trouble setting the input file. Flex++ uses the FlexLexer class provided in FlexLexer.h to create the lexer object(https://github.com/westes/flex/blob/master/src/FlexLexer.h). In my main function I have

Do Regular Expressions only evaluate one line at a time?
Further applications of DFA and NFA: lex or flex, yacc or bison, and POE :-)

Cool C projects
How about writing a programming language using Flex and Bison? There are lots of good tutorials and examples out there.

Parser and Lexer bike-shedding
Some lexer generators (notably Flex) take input from a file handle by default. While you can always read a file into a string before passing it to the generated lexer, this is not seen as "the best" since you have to read in all the data into memory, which can be a lot.

A Good Tool for Resuming Parsers?
Ages ago, I loved writing domain-specific toy languages, and almost always used flex to generate lexers and GNU bison to generate the parser. I've begun a new toy project and I don't think those two will cut it this time, so I'm looking for other tools that integrate well with C++.

Please no
I don't understand :c don't lexers like Flex work off of regex rules? Isn't this the correct first step to parse it?

A work in progress C compiler from scratch
I wrote a C compiler using flex [1] and bison [2]. The glue between them is a bit hacky.
At some point ANTLR [3] looked promising, but these days I'd probably write a lexer and recursive descent parser by hand, then generate LLVM IR.

Dealing with lex and yacc is DIFFICULT so little information is available about them!

Un commento in flex, uno storico software, tanto per mostrare che anche i migliori fanno le cose alla buona.
