Re: [racket-users] Re: ispell

It's been a while but I believe the Windows installers for emacs and latex install ispell as part of their installation. It's a bit heavy handed, but it might be an expedient way to get it done. If you can identify the right executable we can take a crack at a package to install it. S. On Fri, 26

No need to stop at packages - whole languages. (I fancy doing Self when I am a better programmer) On Wed, 24 Feb 2016 at 21:23, Neil Van Dyke wrote: > Brian Adkins wrote on 02/24/2016 02:49 PM: > > it appears to me that Racket is the strongest of the Scheme-ey lisps, so > that's where I'm invest

[racket-users] Racket machine image

Hi, Has anyone ever done a racket machine image like: • Mirage https://mirage.io • LING/Erlang on Xen http://erlangonxen.org • Rumprum https://github.com/rumpkernel/rumprun I heard a podcast and recently saw an old presentation [1] that was interesting. I'm interested, but never had the motivation

Re: [racket-users] Detect version of OS X

what about this? #lang racket/base (require racket/system racket/port) (substring (with-output-to-string (lambda () (system "sw_vers -productVersion"))) 3 5) I get "10" or "11" respectively, and I believe it will run on older versions OS X. s. On Tue, Feb 23, 2016 at 9:38 PM Jens Ax

Do you mean http://docs.racket-lang.org/graphics/Draw__Clear__and_Flip_Operations.html?q=Viewport#%28part._.Pixmaps%29 I've not used the viewports stuff For the racket/gui toolkit I think you can do this by overriding on-paint for a canvas on a frame http://docs.racket-lang.org/gui/canvas___.html

Re: [racket-users] Re: Scribble-string->xexpr ?

I'd prefer to do it in memory. Writing to disk just to read it straight back seems like a lot of effort, and I lose the ability to make pages that are updated on-the-fly. I'll have a look at the source for the pollen and scribble renderers to see if I can separate reading a file from transforming

Re: [racket-users] Re: Scribble-string->xexpr ?

Thanks Matthew, I have two question that I didn't express clearly: 1. A renderer that would create xexpr's for direct consumption of the racket web server. It sounds like pollen will be perfect! (I quickly dismissed writing my own wiki-markup renderer on the basis that scribble already existed) 2.
