Re: [racket-users] How to write string-match?

Thanks Alexis! That's such an elegant solution. I'm a little in awe of all the pieces that you pulled together to make it work. Fantastic! In terms of surface syntax, I think that your straight extension to match is preferable to what I asked for, allowing this sort of thing (match s

Re: [racket-users] How to write string-match?

Excellent idea using a pattern expander. Alexis didn't give an example: > (match "abc--123 foo end" [(str a "--" b " " c " end") (list a b c)]) '("abc" "123" "foo") /Jens Axel 2016-12-20 10:35 GMT+01:00 Alexis King : > One relatively easy solution

Re: [racket-users] How to write string-match?

One relatively easy solution would be to just compile patterns to regular expressions and use Racket’s built-in match form. Writing this as a match-expander is fairly straightforward: #lang racket (require (for-syntax racket/string syntax/parse/experimental/template)

[racket-users] How to write string-match?

While working through many of the puzzles in this year's adventofcode.com I tend to parse the input with a sequence of string-splits. This isn't too bad, but What I'd *really* like is a "string-match" form to more elegantly process structured data, via a few strings based on a simple (and greedy)
