<nanobowers> per an earlier question from postmodern regarding: ⏎ ⏎ > ah ha, you defined default using a generic type T (but i think you forgot to define Option as Option(T) ?) ⏎ ⏎ The problem I eventually ran into was that I am capturing an Hash of String=>Option (where Option is an abstract class, so really any stored hash values would be subclasses of Option), but by defining Option as templated class, I
<FromGitter>
<nanobowers> unsure how to work around this. The `@specs` ivar could be taking any variety of subclasses of Option (e.g. StringOpt, Int32Opt, ... FileOpt, etc.)
<FromGitter>
<Blacksmoke16> define another superclass of `Option` that isnt generic
<FromGitter>
<Blacksmoke16> and use that to type the hash
<FromGitter>
<nanobowers> ok thx, will give that a shot.
<FromGitter>
<Blacksmoke16> is `BaseOption` abstract?
<FromGitter>
<nanobowers> yes
<FromGitter>
<Blacksmoke16> could try switching to a module, or to like `abstract def name : String` in `BaseOption`
<FromGitter>
<mwlang> My google-fu fails me. I'm looking for how to define a Union constant so I can reuse throughout my library? ⏎ ⏎ ```ListenerChannel = Channel(ChannelMessage | ChannelClose | ChannelError)``` [https://gitter.im/crystal-lang/crystal?at=61663a8138377967f44bc271]
<FromGitter>
<Blacksmoke16> you want `alias` not a constant
<FromGitter>
<nanobowers> trying `abstract def name : String ` in `BaseOption` was unsuccessful. If I remove `def name..` from `Option(T)`, then I get this (an expected error): ⏎ ⏎ ```Error: abstract `def Optimist::BaseOption#name()` must be implemented by Optimist::BoolOpt``` ⏎ ⏎ but if i define `def name...` on `Option(T)`, then back to the no overload matches on `Optimist::BoolOpt#name`
<FromGitter>
<Blacksmoke16> try removing the type restriction of `: String`
<FromGitter>
<mwlang> I don't suppose Crystal has the equivalent to Ruby's Array#wrap -- just scanned through the Array class docs and didn't see anything like it.
<FromGitter>
<Blacksmoke16> not built i nno
<FromGitter>
<Blacksmoke16> looks fairly easy to implement tho

<mwlang> it was -- mostly just avoiding reinventing wheels where possible.
<FromGitter>
<mwlang> Trying to set up a Hash that can auto add new keys when missing. I'm not quite getting the block defined right: ``` ⏎ Hash(String, Binance::Handler).new({ |symbol| handler_class.new(symbol) }) ⏎ ⏎ `````` [https://gitter.im/crystal-lang/crystal?at=61664695a41fd20699dde4ee]
<FromGitter>
<mwlang> gives me `Error: unterminated call`
<FromGitter>
<Blacksmoke16> Hash docs have an example of the exact syntax
<FromGitter>
<Blacksmoke16> But you don't pass a block as the value to the constructor
<FromGitter>
<mwlang> I'm looking at the docs...it's just dense to my Ruby-wired brain. :-p
<FromGitter>
<mwlang> oh! found more info further down.
<FromGitter>
<mwlang> it worked! wow. The refactor I just did cleared a bunch of conditionals out of my code base.
<FromGitter>
<Blacksmoke16> Nice!
<FromGitter>
<mwlang> really loving Crystal's Fibers + Channels choice -- that took some getting used to, but every time I work with 'em, I get a little bit better at it.
<FromGitter>
<mwlang> one thing I learned, it's far too easy to clobber a Redis datastore if you have one fiber writing keys while another's reading. I didn't seem to run into that at all with Ruby
<FromGitter>
<mwlang> I reckon I need to throw some mutex.synchronize around those read/write operations.
<FromGitter>
<Blacksmoke16> if you're running in single threaded mode only one would be executing anyway
<FromGitter>
<Blacksmoke16> afaik mutex is only needed with MT mode to prevent more than 1 fiber from accessing a shared resource

<y8> Yay, 1.2.0! ⏎ ⏎ I might regret this, but I've bumped brew formula to 1.2.0 with shards 0.16.0. It still builds without arm64 bottle and I can't build bottle, because `brew install --build-bottle crystal-lang` installs 1.1.0. ⏎ ⏎ So it seems like proper way is to to wait for 1.2.0 formula and then re-try it? Or I can just edit formula locally and then push the bottle? ...
<FromGitter>
<y8> Uh, happy bootstrap day :D ⏎ ⏎ brew install fails with `ld: in '/opt/homebrew/opt/llvm@11/lib/libunwind.dylib', building for macOS-x86_64 but attempting to link with file built for macOS-arm64` on m1, since it uses previous build which is x86, so it's building in rosetta. ⏎ ⏎ Bumping `boot#on_mac_os` resource to `darwin-universal` binary fixes that. Dunno if this will fly with homebrew maintaners, but
<FromGitter>
<Blacksmoke16> dont one of the core devs usually create that?
<FromGitter>
<y8> I'm not sure if they have access to M1's to test it out. And actually contributing is the most fun of the opensource! And as for my terrible mistakes there is always `Request changes` button in PR :D
<FromGitter>
<Blacksmoke16> yes but getting involved in the release process can just add more work to them
<FromGitter>
<Blacksmoke16> maybe it's not a big deal but :shrug:
