Re: [racket-users] Scribble: tables and figures with captions and numbering?

You can assign numbered captions to figures with `figure` from `scriblib/figure` (and reference them with `figure-ref`). http://docs.racket-lang.org/scriblib/figure.html I don't know how to caption tables or number equations in Scribble. On Thu, Jul 6, 2017 at 7:50 AM, Dmitry Pavlov

Re: [racket-users] Random values in Typed Racket?

I wouldn't suggest using `set!` that way -- I'm a big fan of internal `define`. Sam On Thu, Jul 6, 2017 at 12:19 PM, David Storrs wrote: > > > On Thu, Jul 6, 2017 at 8:53 AM, Sam Tobin-Hochstadt > wrote: >> >> Just for clarity, here's an example

Re: [racket-users] Random values in Typed Racket?

Just for clarity, here's an example using `set!` and `define`, although I wouldn't really suggest this style: #lang typed/racket (: f : Real -> Real) (define (f x) (define rand-value (random)) (define new-value (+ x rand-value)) (set! new-value (- new-value x)) new-value) Sam On Wed,

[racket-users] Scribble: tables and figures with captions and numbering?

Hello, I have zero experience with Scribble, and today I have been considering using it to document a program. Previously, I have been using LaTeX, Markdown, and Word. One of the first questions that comes to mind is: can I assign captions to tables (rendered above the table) and figures

[racket-users] low-friction app extensibility in racket

Let's say I'd like to move Racket apps closer to old-school Emacs-like extensibility. Such as very-low-friction way to use arbitrary Racket code to set app preferences, and to hook into behavior of the app and add features. And generally encouraging everyone to get their hands dirty coding
