I could do that but it's only using handy/test-more and the build server is
going to have no idea what to do with test-more tests as opposed to
rackunit tests.

What I suppose I could do is make test-more run a rackunit test at the end
that verifies no tests failed so that the build server could do something
useful with it.  Will the build server care if there is STDOUT ouput from
the tests?

Doh.  I went through that page, but clearly not carefully enough.  Thanks
for the pointer.

[racket-users] add set-subset?

['John Clements' via Racket Users]

It seems strange to me that we have (AFAICT) set-union, set-subtract, and 
set-member?, but not set-subset?. Would it make sense for me to propose a pull 
request for this? (it would just be (set-empty? (set-subtract b a)), I realize…)

D’oh! It’s just called subset?

Sorry,

I am so glad that I'm not the only one who does this.

I believe the workshops weren't recorded.

One of the workshop attendees had the great idea of using gitter.im to 
facilitate live discussion, as well as make a transcript available 
afterwards (though you may find the written record somewhat incomplete, 
since we were often clarifying things verbally and face-to-face, in 
addition to using the chat). See


  https://gitter.im/racketon-web-devel-workshop/Lobby

I intend to polish the code and notes (that is, the package docs). If

How about a pull request that redirects searches for "set-subset?" to
the `subset?` function?

Re: [racket-users] package for the RacketCon 2018 web devel workshop

[Sage Gerard]

Hey all,

Thanks again for the workshop, Jesse!

After setting up the room I went ahead and escalated use of chats to Jay
for next year.
We should be able to get something relatively more complete by then.

The transcript is only really necessary if you specifically need the text
file, and it's near
the bottom of the chat. It may be hard to see since Gitter just displays
the uploaded file as
a vanilla link.

[racket-users] Re: Racket Language Track for Exercism

[Dave McDaniel]

Little necrobump here, I did find exercism recently in my efforts of 
getting up to speed on racket, in addition to the racket-koans 
 collection on github, which 
is great!  The idea of having real people give you feedback on the code is 
awesome.  That said, with the racket track there are only 2 mentors and 
this impacts the pace at which you can proceed, a simple little exercise 
may sit for a couple weeks before someone takes a look.  Looks like they 
need some more racket mentors over there ; ).

Even with the slow pace I still recommend it to anyone wanting to take a 
look at learning a new language, having real people give you feedback is 
great compared to just a unit test passing.

Re: [racket-users] servlet development in REPL

[Greg Hendershott]

I just wanted to chime in and say I share Philip's preference.

I think programming is hard enough without multiple sources of truth.


p.s. Replacing expensive startup items with a no-op is a good idea. Or
sometimes, keep the "real-op" but postpone using one of:

- `delay/sync` and `force` from `racket/promise`:


https://docs.racket-lang.org/reference/Delayed_Evaluation.html#(form._((lib._racket%2Fpromise..rkt)._delay%2Fsync))

- `lazy-require`:


https://docs.racket-lang.org/reference/lazy-require.html#(form._((lib._racket%2Flazy-require..rkt)._lazy-require))

The former for individual definitions, the latter for entire modules.

Would it help to put `handy` in `build-deps` instead of `deps`?

Near the bottom of https://docs.racket-lang.org/raco/setup-info.html
where the compile-* options are mentioned, it links to the docs for
`compile-collection-zos` where there's more explanation:

  
https://docs.racket-lang.org/raco/API_for_Raw_Compilation.html#%28def._%28%28lib._compiler%2Fcompiler..rkt%29._compile-collection-zos%29%29


As for usage examples: I usually grep the Racket source and/or use
GitHub search:

  https://github.com/search?=Codel=Racket=compile-omit-paths

[ In fact I should probably make that into a little Emacs command that
prompts for the last query parameter then does `browse-url`. :) ]
