Scanners suitable for syntax highlighting?

Are there any Clojure or EDN scanners which are useful for syntax highlighting? What would make it useful: 1. It reads '(foo) as left-paren, symbol "foo", right-paren rather than '(foo) (this is because brackets are highlighted independently). 2. It keeps line number and column number informatio

Re: Thoughts on a curly-infix reader macro?

Odd-entry-count maps would have corner cases: One would need to use an even number of unary operators. If an odd number of unary operators were used, what looked like a valid expression would become a map, and that might be hard to figure out. Also, since the order of entries in a map is not guar

In the original post: > I had been writing elegant but deeply nested Clojure code that was very difficult to read ... I focus on expressivity, specifically because of the write-only phenomenom. This isn't peculiar to clojure; this happened a lot in the Perl days (so much so, that that's where I

Re: Proposing a new Clojure documentation system (in Clojure)

Personally, I like documentation in the same place as the code it documents And I'd love to have the tests in the same file as well. In both cases, I think the things are highly coupled by their nature, and therefore I want them together (OK, tests aren't always - in the cases they aren't, pu

Re: [ANN] packthread 0.1.0

Hi! I'm pretty familiar with legal license stuff (though IANAL). I wouldn't mind considering changing it at the point where someone wants to use it but can't - because that would carry with it a specific reason we can think about. -Jason On Fri, May 2, 2014 at 3:03 PM, James Reeves wrote: >

Re: Are zippers the right choice for "sequence-like" trees?

In general, I've found that zippers make complicated edits super-easy, while a recursive phrasing of the same algorithm - if it exists and isn't super complicated to write - performs better and gives more control over structural sharing. I might prove out an algorithm with zippers, but when the pe

Hi Aravindh! I've found the leiningen source very clean and well organized. It was one of the first production products that I read through, and it has the benefit that you're probably familiar with what it does and will probably want to extend or configure it. On Mon, Feb 3, 2014 at 2:47 AM, A
