00:36 <tilpner> franzejr - Based s/in/on/?

00:36 <franzejr> thanks! typo!

00:37 <franzejr> What did you think about the site, tilpner?

00:38 <tilpner> Looks nice, but I didn't feel like making an account.

00:38 <franzejr> It's similar what Hacker News does

00:39 <tilpner> I have HN and Reddit for news already. It's similar, but much smaller and more narrow in scope.

00:40 <tilpner> The smaller part is of course not your fault, but I don't know how to get something like that going. :/

00:40 <franzejr> Do you know RubyFlow? The idea was similar to Rubyflow. I also don't know it's just a try :)

00:40 <franzejr> http://www.rubyflow.com/

00:41 <franzejr> Something just centered in Crystal

00:42 <tilpner> No, I don't really use Ruby.

00:42 <franzejr> Yeah. So, Ruby community use a lot RubyFlow...

05:18 <wim_> HI, I'm following the 'Getting Started' page for Sidekiq at https://github.com/mperham/sidekiq.cr/wiki/Getting-Started. On compilation, if get the error: "Error opening file '/home/wim/projects/try/crystal/try/sample/libs/sidekiq/sidekiq/../../web/views/dashboard.ecr' with mode 'r': No such file or directory (Errno)". I believe I'm missing a shard, could anyone help me add it?

05:19 <wim_> For anyone taking a looking at the page, I'm trying to run the web.cr demo program.

05:52 <BlaXpirit> wim_, hmm i think it needs to be ran differently, maybe from a different folder

05:54 <BlaXpirit> e.g. cd folder; crystal prog.cr instead of crystal folder/prog.cr

06:16 <wim_> BlaXpirit, I compile from the top folder, but the error comes from a source file lower down. Also, the file 'web/views/dashboard.ecr' is missing.

06:17 <BlaXpirit> wim_, k but for real try what I said

07:48 <wim_> BlaXpirit, did that, no change. How can I find out which shard '../../web/views/dashboard.ecr' is supposed to be?

07:49 <BlaXpirit> wim_, ??? it's here https://github.com/mperham/sidekiq.cr/blob/master/web/views/dashboard.ecr

07:52 <BlaXpirit> works here. examples$ crystal build web.cr

08:02 <wim_> BlaXpirit, the web subdir of sidekiq hasn't been loaded with the shard. Should I download this separately?

08:02 <BlaXpirit> wim_, I think you should git clone instead

08:03 <wim_> Hm. I've been following the 'Getting Started' literally. No mention of this. Perhaps I should report an issue to mperham about this.

08:03 <wim_> OK, will try that.

08:04 <BlaXpirit> wim_, hm weird. well here's what I did: git clone https://github.com/mperham/sidekiq.cr && cd sidekiq.cr && crystal dep && mv libs examples && cd examples && crystal build web.cr

08:04 <wim_> ok thanks.

08:47 <Davy_CC> I got a error when I'm using Regex#match with a block "'Regex#match' is not expected to be invoked with a block, but a block was given"

08:48 <Davy_CC> it's described in the API: http://crystal-lang.org/api/Regex.html

08:49 <BlaXpirit> Davy_CC, what are you looking to achieve?

08:50 <Davy_CC> if the regex is matched, then do some thing

08:51 <Davy_CC> I know that I can do `md = /bla/.match "blablabla"; unless md.nil?; dosomething; end`

08:52 <BlaXpirit> >> if "...abc..." =~ /a(\w)c/; p $~[1]; end

08:52 <DeBot> BlaXpirit: "b" - more at https://carc.in/#/r/120b

08:52 <Davy_CC> but the doc wrote the example for block, so I just try it

08:53 <BlaXpirit> Davy_CC, sure enough, the examples on top don't all work

08:53 <Davy_CC> so the block supporting is removed or not implement yet?

08:54 <BlaXpirit> Davy_CC, possibly removed because it is not needed

08:55 <BlaXpirit> in fact the `match` method is extremely misleading, i'd remove it as well

08:55 <Davy_CC> I think that's useful when I only want to do something if it's matched, but `$~` or the return of `#match` can be Nil | MatchData

08:57 <BlaXpirit> >> if m = (/a(\w)c/.match("...abc...")); p m[1]; end

08:57 <DeBot> BlaXpirit: "b" - more at https://carc.in/#/r/120c

08:57 <BlaXpirit> DeBot, also it seems like the example above demonstrates that $~ can't be nil

08:58 <BlaXpirit> oh good, it has a not nil assertion

08:58 <Davy_CC> yes...

09:04 <Davy_CC> anyway, I'll open a issue for the api doc

09:08 <Davy_CC> BlaXpirit: https://github.com/crystal-lang/crystal/commit/93a2e66de2246c2d65f0acec57d9a06cc5869e25

09:08 Philpax_ has joined #crystal-lang

09:08 <Davy_CC> so it raised

09:08 Philpax has quit [Ping timeout: 260 seconds]

09:09 <BlaXpirit> Davy_CC, well no, $` raises now but it was nilable before

09:09 soveran has joined #crystal-lang

09:10 <BlaXpirit> this commit shows how it went from $~ : MatchData + having to check for MatchData::EMPTY to $~ : MatchData | Nil but now it seems to be $~ : MatchData again but if you use it it can raise

09:10 <BlaXpirit> and when I wrote $` I meant $~

09:11 <Davy_CC> oops you're right

09:12 soveran has quit [Remote host closed the connection]

09:13 <Davy_CC> And it seems that block never supported in the history (I watched the git history of /src/regex.cr)

09:14 soveran has joined #crystal-lang

09:16 <BlaXpirit> honestly it almost seems worth implementing an automatic checker of validity of examples in docs

09:16 <Davy_CC> lol

11:12 soveran has quit [Remote host closed the connection]

11:19 <Davy_CC> I found some problem that Float64 doesn't have `to_json` method

11:19 <Davy_CC> >> 1.0.to_json

11:19 <DeBot> Davy_CC: undefined method 'to_json' for Float64 - https://carc.in/#/r/120e

11:20 <BlaXpirit> Davy_CC, require "json" ?

11:20 <BlaXpirit> https://carc.in/#/r/120f

11:23 <Davy_CC> oops, but why I can type `1.to_json` and works fine in playground but not `1.0.to_json`

11:24 <BlaXpirit> Davy_CC, maybe playground uses json for something, or includes it for convenience

11:24 <BlaXpirit> but everything is consistent, either both work or both don't

11:25 <Davy_CC> but if `Int#to_json` is included, why `Float#to_json` is not included at the moment? loads the file of the definition is the same one

11:25 <Davy_CC> s/loads//

11:26 <BlaXpirit> Davy_CC, see my last message

11:26 <Davy_CC> oh i see

11:26 <Davy_CC> thanks
