Cool. Thanks a lot for uploading this. I have a question (and I confess that I haven't checked the link). How is this related to or overlaps with cv-combinators? Cheers Ivan On 28 September 2013 06:18, Arjun Comar nru...@gmail.com wrote: After receiving feedback, I went ahead and split out

I think they do work. cv-combinators depends on HOpenCV, which depends on OpenCV 2.0. On 28 September 2013 16:03, Arjun Comar nru...@gmail.com wrote: No, these are unrelated. Cv-combinators hasn't really worked since OpenCV 2.0 waa released I believe. On Sep 28, 2013 8:54 AM, Ivan Perez

[Haskell-cafe] What class for splittable data / balanced-fold?

2013-09-28 Thread Ryan Newton
Hi all, We all know and love Data.Foldable and are familiar with left folds and right folds. But what you want in a parallel program is a balanced fold over a tree. Fortunately, many of our datatypes (Sets, Maps) actually ARE balanced trees. Hmm, but how do we expose that? It seems like it

2013-09-28 Thread Arjun Comar
Fair enough, it's been two or three years since I tried to play with them. Most of my work is in the raw bindings currently, which provide the C++ API in Haskell, so much lower level that cv-combinators. If HOpenCV were to incorporate parts of these bindings then cv-combinators would be able to

The people working on HOpenCV are very open to incorporating other's programmer's patches. Maybe you can incorporate your changes to cv-combinators? (Project's been halted since 2010, I'm sure they'll be very happy to see that sb is contributing). On 28 September 2013 19:13, Arjun Comar

2013-09-28 Thread Arjun Comar
I've been talking to Anthony Cowley who I think is the current maintainer of HOpenCV and Ville Tirronen who has been developing the CV bindings. Basically the consensus is that these raw bindings provide a new base to work from, and it's worthwhile to rethink the API we provide with a fresh start.

Is it possible to change fonts? I have found that fonts (and shadows) have a huge impact on the wow-factor of a plot. In fact, I could not help but ask a speaker during a talk what font he used for a particular plot... it just looked great! I think all charts support setting a custom font

this is a funny trick, and it looks saner than the more general $ * combinators. i see many situations where i could use that to lift my own combinators, or to replace the backticks (``) to lift the infix function. thx - marc Gesendet: Freitag, 27. September 2013 um 21:51 Uhr Von: Thiago Negri
