I'm working on a domain-specific language (DSL) for non-programmers. Non-programmers make a lot of grammar mistakes: they misspell keywords, they don't close parentheses, they don't terminate blocks, etc.

Are lexers and parsers really that different in theory ?
It seems fashionable to hate regular expressions: coding horror, another blog post.
However, popular lexing based tools: pygments, geshi, or prettify, all use regular expressions. They seem to lex anything...
When is lexing enough, when…
