Re: [racket-users] PLT policy on Travis CI bandwidth costs

Greg's Travis CI repo has a branch for using Travises cache, so that each project would only download Racket once (per release). I don't know what its state is though? It seems like that would be idea if it works. https://github.com/greghendershott/travis-racket/tree/use-cache On Thu, Apr 2,

Re: [racket-users] Capturing sets of options in a splicing syntax class?

try `syntax/parse/experimental/template`. It gives you access to `??', which basically says use a if present, else b, and some other cool templates besides. From the docs: (syntax-parse #'(m 1 2 3) [(_ (~optional (~seq #:op op:expr)) arg:expr ...) (template ((?? op +) arg ...))]) #syntax:197:0

[racket-users] using a different "scribble.tex"

Hey all, I'm currently trying to use a custom tex style file with scribble. Unfortunately this style file conflicts with the line "\usepackage[usenames,dvipsnames]{color}" in the "scribble.tex" file include by the scribble to tex compiler. Is there any way to tell scribble to use a different

Re: [racket-users] Unicode subscripts in code and scribble

They way I've worked around this in the past is to render the problematic character as a Pict and then drop that Pict into the scribble document. Doing that has some problems but it can service if you can't get the character you want into scribble. On Thu, Mar 10, 2016, 9:19 AM Vincent St-Amour <

This is a little bit of a hack and weakens the handin server security but adding the following to the top of your checker file should make this error go away: ``` (require handin-server/sandbox) (sandbox-path-permissions (cons (list 'read"/") (sandbox-path-permissions))) ```

For symmetry there is "make-immutable-hash", which is like "hash" but has the interface of "make-hash". (I don't know why "hash" is the way it is though). --spencer On Wed, Dec 7, 2016 at 10:49 AM David Storrs wrote: > -> (hash 'a 1 'b 2) > '#hash((a . 1) (b . 2)) > >

Re: [racket-users] pict polygons

2htdp/image works with pict directly (they are pict-convertible?, and all pict functions accept those). If that does work for whatever reason, it shouldnt be terrible to write that function using ‘dc’ and ‘dc-path%’, and it would make a great PR to ‘pict’! —spencer On Tue, Dec 17, 2019 at 8:15

You could use pict/convert to make a wrapper that remembers the color: ``` #lang racket (require pict pict/convert) (struct pict+color (pict color) #:property prop:pict-convertible (lambda (x) (pict+color-pict x))) (define (my-colorize p c) (pict+color (colorize p c) c)) (define
