Hi everyone. I have a test of a user-related function that I don't can see why don't work : #lang racket (require rackunit) (require "../../main.rkt") (check-equal? (with-output-to-string (lambda () (with-input-from-string

Re: [racket-users] Running raco setup from within DrRacket?

p.s. If you wanted to do a general thing, for DrRacket, this is what I was referring to. The README is probably enough of a hint, you don't need to read the Emacs Lisp. :) https://github.com/purcell/exec-path-from-shell On Sat, Feb 16, 2019 at 10:07 PM Greg Hendershott wrote: > > From unsophisti

>From unsophisticated searching the source, it looks like the code to implement deps checking is in setup/private/pkg-deps.rkt -- "private" meaning you're not supposed to use it directly. It seems to be called from the `setup-core` function provided by (non-private) setup/setup-core.rkt. That seem

p.s. As another example of the current breakage: All my own packages that do have documentation, have yellow "This package needs documentation" demerit badges, at the moment. On Sat, Feb 16, 2019 at 9:17 PM Greg Hendershott wrote: > > The package web site seems to think no packages have been buil

Re: [racket-users] Questions about Scribble docs

The package web site seems to think no packages have been built: The "Most recent build results" item is blank for every of the dozen packages I just checked. So I think that's one problem. When that's working normally, as it usually does, there are two levels of refresh: 1. The package catalog

[racket-users] Questions about Scribble docs

Do I need to do something particular to make the package server notice my documentation? I've got a scribblings/struct-plus-plus.scrbl file but the package server is still listing it as "needs documentation". Separate but related, when I install a module and it builds the documentation, is there

Re: [racket-users] Python's append vs Racket's append and helping novices understand the implications

I struggled with whether to send that message… I saw the name, “random access lists”, thought, “hmm, I wonder what that would like”, and clicked on the link. I wound up reading a bit about whether I should use (first impresssion) superficial or in-depth contracts, and ran out of steam pretty qui

Re: [racket-users] Python's append vs Racket's append and helping novices understand the implications

There are several examples for every function provided by the ralist library. (And it's almost verbatim what's in the Racket reference for pairs and lists.) But... I can add some early examples. No problem. David On Sat, Feb 16, 2019, 4:00 PM John Clements wrote: > The pointer to RaLists wou

Re: [racket-users] Contracts question on structs

Hi Chris, I just pushed an update to struct-plus-plus that I think does what you want. https://pkgd.racket-lang.org/pkgn/package/struct-plus-plus The package server is telling me "This package needs documentation". I'm not sure why that is, since I've got scribblings/strut-plus-plus.scrbl and I

Good to know; I also use define-runtime-path with abandon, and was not aware of possible consequences of casting too wide a net. Thanks! John > On Feb 10, 2019, at 09:49, Philip McGrath wrote: > > I think this is probably a consequence of the quirk of `define-runtime-path` > with directories

Re: [racket-users] Python's append vs Racket's append and helping novices understand the implications

The pointer to RaLists would be much more enticing if we could convince David Van Horn to begin his documentation with a couple of small examples…. John > On Feb 13, 2019, at 14:35, Stephen De Gabrielle > wrote: > > Thanks > > I should note that anyone with a GitHub account can edit > htt

Thank you both -- Jon for the code and Alexis for the thorough description. Alexis, this was exactly what I was looking for. I've been frustrated with macros because I kept trying and failing to figure out a mental model of what the heck was going on under the hood. I had some of the basics, but

[racket-users] Alpine-based docker racket images

Hi all, Just a quick note to let anyone interested know I've built some Racket 7.2 docker images: one "full" and one "minimal", from the respective source tarballs, and for both "x86_64" and "aarch64". I'm still working on armhf. There's also a manifest set up against tags "latest" (for full) a
