Description
Flex
Flex is a popular tool known for being a super-fast lexical analyser. It's open-source, totally free, and works on multiple platforms as a command-line app written in C/C++. It’s designed to help you generate scanners right from the start.
What Does Flex Do?
The scanners that Flex creates can recognize patterns in text. So, if you’re looking for applications that can do pattern matching on text, you've found one! Just remember: don’t confuse it with the non-GNU version of Lex.
How Does It Work?
When you use Flex, it generates a C source file called lex.yy.c. This file includes a function named yylex(). Since it's a command-line tool, you can easily run it through any terminal emulator.
User-Friendly Command-Line Options
You’ll find that the command-line options are grouped into categories like table compression, debugging, files, scanner behavior, and more. If you want to see all these options quickly, just run the ‘flex --help’ command after installing it on your machine.
Table Compression Features
The table compression options let you build equivalence classes and use different ways to represent tables. You can also choose whether to compress tables or not. Plus, there’s an option to create large and fast scanners!
Troubleshooting with Debugging Options
If you need to troubleshoot your scanner, Flex has got your back! You can turn on debug mode, write summaries of scanner stats to stdout, or even run Flex in trace mode. Want detailed reports? You can write backup info to files too!
Customize Your Scanner Behavior
You have control over how your scanner behaves through various command-line options. This includes generating 7-bit or 8-bit scanners and tracking line counts with yylineno. Whether you're making an interactive scanner or a batch one, Flex lets you customize it just how you like.
Your Platform Compatibility
This software is crafted entirely in C and C++, making it compatible with Linux and FreeBSD operating systems. Currently, it supports both 64-bit and 32-bit instruction sets.
