18:17 <FromGitter> <moe:busyloop.net> hrm, why does https://github.com/crystal-ameba/github-action build ameba from scratch every time

18:17 <FromGitter> <moe:busyloop.net> eatin' up all my build minutes :(

18:19 <FromGitter> <Blacksmoke16> prob more so a symptom of installing all shard deps each build

18:20 <FromGitter> <Blacksmoke16> could prob cache those and it would be fine

18:22 <FromGitter> <moe:busyloop.net> well yea, it uses the crystal container and then does a shards install for ameba, which spends 5 minutes compiling...

18:24 <FromGitter> <moe:busyloop.net> why not just curl the release binary or use a container that has it already baked in :confused_parrot:

18:26 <FromGitter> <Blacksmoke16> fair point, open an issue about it?

18:26 <FromGitter> <moe:busyloop.net> you mean complaining on matrix is not enough?

18:27 <FromGitter> <moe:busyloop.net> sigh... okeh

18:47 <FromGitter> <moe:busyloop.net> oh, i might see the problem. ameba doesn't seem to publish binary releases. hmpf.

18:50 <FromGitter> <Blacksmoke16> sounds ya need to make 2 issues then :P

18:51 <FromGitter> <moe:busyloop.net> nah, sounds more like 1 to me. on main crystal. "put ameba in stdlib already, `crystal lint`"

18:53 <FromGitter> <moe:busyloop.net> but i'll leave that for later, for now will just drop the linting from my action :P

18:55 <FromGitter> <Blacksmoke16> is it within a private repo?

18:56 <FromGitter> <moe:busyloop.net> yup. in public i'll leave it on as i don't push those that often anyway

18:56 <FromGitter> <moe:busyloop.net> just in this private wip it was getting a bit annoying. no biggie anyway, just biking the shed...

19:03 <FromGitter> <Blacksmoke16> could ofc make it so it only runs when you open a PR and each commit after its opened

19:03 <FromGitter> <Blacksmoke16> but fair enough :P

19:18 <FromGitter> <moe:busyloop.net> yea but shouldn't have to, 5min is too long for a linter

19:18 <FromGitter> <Blacksmoke16> it takes 5min to build? 🤔

19:18 <FromGitter> <moe:busyloop.net> yep

19:19 <FromGitter> <Blacksmoke16> wew, it takes 20s for my CI builds

19:20 <FromGitter> <moe:busyloop.net> using that same github action? 🤔

19:20 <FromGitter> <Blacksmoke16> no just doing https://github.com/athena-framework/athena/blob/master/.github/workflows/ci.yml#L29-L40

19:22 <FromGitter> <moe:busyloop.net> hm, not sure what extra stuff the action is doing

19:22 <FromGitter> <moe:busyloop.net> but a solid 5min here 🤷

19:22 <FromGitter> <Blacksmoke16> https://github.com/crystal-ameba/github-action/actions/runs/3590834831/jobs/6044664703#step:2:53

19:22 <FromGitter> <Blacksmoke16> seems it builds in release mode

19:22 <FromGitter> <moe:busyloop.net> ow... yea, that explains it

19:23 <FromGitter> <moe:busyloop.net> well, but i can see how fixing it is prob a bit complicated, since ameba doesn't have binary releases

19:23 <FromGitter> <moe:busyloop.net> so i'll quit whining for a bit

19:23 <FromGitter> <Blacksmoke16> it's its own crystal application so yea that would do it

19:24 <FromGitter> <moe:busyloop.net> yea, easiest might be to bake a docker image with it and use that in the action

19:24 <FromGitter> <moe:busyloop.net> but then you have to think about quota allowances in the docker registry etc.

19:24 <FromGitter> <Blacksmoke16> ameba installs quickly (like <20s) then it builds another crystal app in release mode that takes a while

19:25 <FromGitter> <Blacksmoke16> so unless you care about it reporting failures in the PR diff, prob easier to just run it w/o the action itself. or have an issue about building it non-release mode. \cc @veelenga

20:33 <FromGitter> <moe:busyloop.net> yea that's what i had before. switched to the action because i liked the fancy github report

20:33 <FromGitter> <moe:busyloop.net> but it's not that important anyway, was just surprised why the official ameba action is so slow

20:59 <FromGitter> <toast:matrix.quietfeathers.space> With a union type is there a way to make a call only if the value is of a given type?

20:59 <FromGitter> <Blacksmoke16> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=63b9dd437de82d26161a31bf]

21:00 <FromGitter> <toast:matrix.quietfeathers.space> More concretely, I'm pulling a value from a json blob that may or may not be there I'm doing `json["key"]?` and I'd like to call `as_s` chained after that, but it doesn't work because of the union type

21:00 <FromGitter> <Blacksmoke16> can also use a `case` https://crystal-lang.org/reference/1.6/syntax_and_semantics/case.html#union-type-checks

21:00 <FromGitter> <Blacksmoke16> got an example of the error?

21:00 <FromGitter> <toast:matrix.quietfeathers.space> oh that might help, I can make a helper that just defaults to empty string if the value isn't there

21:01 <FromGitter> <Blacksmoke16> is the structure of the data known ahead of time?

21:01 <FromGitter> <toast:matrix.quietfeathers.space> it is

21:01 <FromGitter> <Blacksmoke16> have you looked into https://crystal-lang.org/api/JSON/Serializable.html?

21:02 <FromGitter> <toast:matrix.quietfeathers.space> that's probably the better solution

21:02 <FromGitter> <toast:matrix.quietfeathers.space> thanks for your help!

21:02 <FromGitter> <Blacksmoke16> 👍

23:52 <FromGitter> <abduct> hey all. im trying to generate every possible x, y, z coord between -50 and 50 to test a robot kinematics but it seems i have misunderstood the Array#combinations method? it seems it doesnt actually generate each combination. for example [1, 1, 1] does not exist?

23:53 <FromGitter> <abduct> here is my iterator loop: https://carc.in/#/r/ecm6

23:54 <FromGitter> <abduct> here is the iterator with logic testing for the 1, 1, 1 case: https://carc.in/#/r/ecma
