Why would someone use flex as opposed to writing there own lexer? I am
developing my own scripting language and find it much simpler to
create a lexer on my own, that way I can tailor it to my needs. What
makes using flex any easier, the code it generates is very large and
confusing even for a simple lexer.
From: Frank Hale
[Writing your first flex lexer takes a while. After that, I find it
much faster than hand-coding. Also, if you can arrange your lexer so
it doesn't have to back up, which is usually possible, it's generally
faster than hand-coded because of the DFA pattern matching engine.
