02:14 <FromGitter> <PlayLights_twitter> Why I can't do this `alias ClientParams = { id: 1, name: "us" }.class` ?

02:18 <FromGitter> <mwlang> when writing a crystal spec and comparing timestamps, what should the `delta` be if I want 1 second accuracy between two timestamps?

02:19 <FromGitter> <dscottboggs_gitlab> `1.second`?

02:23 <FromGitter> <dscottboggs_gitlab> or maybe `1.second - 0.01.seconds`

02:23 <FromGitter> <mwlang> that worked. For some reason, I thought that was a rails thing rather than Ruby thing

02:23 <FromGitter> <mwlang> so didn't expect it to work in crystal

02:24 <FromGitter> <dscottboggs_gitlab> haha well either way that doesn't tell you whether its a Crystal thing

02:26 <FromGitter> <mwlang> True! gotta admit though, if it works in Ruby, high likelihood it was implemented in Crystal....which is one of the reasons I'm loving this language.

03:19 <FromGitter> <3n-k1> why does this macro only work if it's excluded from the module? https://play.crystal-lang.org/#/r/9k47

03:21 <FromGitter> <Blacksmoke16> well the issue is more so you're using an ivar at the class level

03:23 <FromGitter> <3n-k1> does that matter if i'm passing it to a macro?

03:23 <FromGitter> <Blacksmoke16> yes, becaues it doesnt exist

03:24 <FromGitter> <3n-k1> it doesn't exist at compile time?

03:24 <FromGitter> <Blacksmoke16> it doesnt exist within the class, only the instance

03:24 <FromGitter> <Blacksmoke16> https://crystal-lang.org/api/master/Object.html#delegate(*methods,toobject)-macro

03:24 <FromGitter> <Blacksmoke16> prob just should use this tho

03:25 <FromGitter> <3n-k1> well yeah but the macro transforms it so that it's only- that works

03:25 <FromGitter> <Blacksmoke16> hm

03:26 <FromGitter> <3n-k1> why is delegate able to use an instance variable?

03:26 <FromGitter> <Blacksmoke16> not sure, maybe passing it via a named arg? :shrug:

03:27 <FromGitter> <3n-k1> huh, interesting

03:52 <FromGitter> <mwlang> any idea what's wrong with this? ⏎ ⏎ ```Array.new(10).size.times.map(&:itself) ⏎ # => [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] ``` [https://gitter.im/crystal-lang/crystal?at=5f3b506b5d0f8f24407a0cfe]

04:12 <FromGitter> <wyhaines> @mwlang Calling `times` like you did returns an instance of `Iterator` (a `TimesIterator`). Calling `map` on that just returns another kind of `Iterator`. However, if you call `to_a` on that, the iterator is traversed, and you end up with an array again. ⏎ ⏎ ```Array.new(10,0).size.times.map {|i| i}.to_a``` [https://gitter.im/crystal-lang/crystal?at=5f3b553d85c0f2132fd66668]

04:42 <FromGitter> <mwlang> @wyhaines Thanks for explaining that. I didn't know how to interpret what Crystal compiler was telling me. Now it makes perfect sense.

05:00 <FromGitter> <wyhaines> @mwlang FWIW, you can achieve the same effect more simply: `Array.new(10) {|i| i}`

06:07 <FromGitter> <grkek> Hello

06:07 <FromGitter> <grkek> I did an example project for the Grip framework, if anyone is interested in it check it out https://github.com/grkek/bakuriani

06:08 <FromGitter> <grkek> @Blacksmoke16 1 star and we are on-par with popularity of our frameworks

10:05 <FromGitter> <alexherbo2> how to alias a method?

10:06 <FromGitter> <alexherbo2> I want `get` with no parameter to forward to `all`

10:06 <FromGitter> <alexherbo2> (I have multiple `get` implementation`

10:45 <FromGitter> <alexherbo2> how to display the help of a subcommand? (what `mycommand -h subcommand` show)

10:45 <FromGitter> <alexherbo2> I want to add a `:show` command displaying the subcommands of it

10:48 <FromGitter> <neutrinog> hey I can't seem to get HTTP::Cookie working. I'm creating a cookie and adding it to the response but it's not showing up in the browser. Any suggestions?

10:57 <FromGitter> <neutrinog> nvm. there was a problem with my cookie settings.

12:10 <FromGitter> <wyhaines> @alexherbo2 ⏎ ⏎ ```def get ⏎ all ⏎ end``` ⏎ ⏎ There is no built-in alias functionality. [https://gitter.im/crystal-lang/crystal?at=5f3bc531a05e464346d1ca74]

12:20 <FromGitter> <wyhaines> @alexherbo2 You should be able to write a macro to implement a method alias functionality, if you really want it, but the general Crystal philosophy is that if we have one way of calling something, we don't need 2. If you are replacing one method with another in your API, just manually create the alias, and when it's appropriate in your product release cycle, mark the old one as deprecated: ⏎ ⏎

12:20 <FromGitter> ... https://crystal-lang.org/api/0.35.1/Deprecated.html

18:48 <FromGitter> <alexherbo2> how to continuously capture command output?

18:49 <FromGitter> <alexherbo2> I want to execute code with inotifywait monitoring

19:44 <jhass> use Process.run with a block, you're yielded an instance of Process, Process#output is an IO

21:37 <FromGitter> <spencerking> I'm trying to write a library and am running into some issues. My library module has a method called "tokenize" but in my spec when I try to call LIBRARY.tokenize I get the error undefined method 'tokenize' for module

21:39 <FromGitter> <Blacksmoke16> did you define it as `def self.tokenize`?

21:41 <FromGitter> <spencerking> I did not, let me try that

22:09 <FromGitter> <spencerking> That seems to have worked, thanks for the help

22:38 <FromGitter> <alexherbo2> is it possible to sort a hash by their keys?

22:38 <FromGitter> <Blacksmoke16> other than creating a new hash and inserted the items in order? no

23:38 <FromGitter> <dscottboggs_gitlab> hash order isn't guaranteed, though, right? so the only way would be to do like `.each.to_a` and sort by the first element of the tuple

23:49 <FromGitter> <Blacksmoke16> Hashes are ordered, says so in the API docs

23:49 <FromGitter> <Blacksmoke16> That the order is based on insert order

23:51 <FromGitter> <dscottboggs_gitlab> ok then
