13:05 <jokke> is there a guard equivalent for crystal?

13:21 <RX14> jokke, what do you mean?

13:22 <jokke> i mean a dsl to set up file watchers which trigger actions when files have been changed/added/deleted etc

13:22 soveran has joined #crystal-lang

13:22 soveran has quit [Changing host]

13:22 soveran has joined #crystal-lang

13:22 <jokke> mainly for running specs

13:22 <jokke> see guard-rspec on github

13:25 <RX14> jokke, https://github.com/f/guardian

13:25 <RX14> but I much prefer entr because it's more unixy

13:25 <jokke> sweet!

13:25 <jokke> what's entr?

13:26 <jokke> oh ok

13:27 <RX14> jokke, http://entrproject.org/

13:27 <RX14> it's different and more manual but i like it

13:27 <jokke> hmm

13:27 <RX14> mainly because I can just string together a small commandline instead of creating a file

13:27 <RX14> depends how many rules you have

13:28 <RX14> I tend to only have one

13:28 soveran has quit [Remote host closed the connection]

13:28 <RX14> find src -type f -name '*.cr' | entr -r crystal build foo.cr

13:29 <jokke> yeah..

13:29 <jokke> i'd need at least two

13:30 <jokke> one for running specs when spec files change and one for running corresponding specs when source files change

13:30 <jokke> but i see that guardian cannot do that either

13:30 <RX14> wouldn't that just be one?

13:30 <RX14> find src spec -type f -name '*.cr' | entr -t crystal spec

13:31 <RX14> -r*

13:31 <jokke> that would run all specs

13:31 <RX14> yes

13:31 <RX14> it doesn't take long...

13:31 <jokke> yes but it's distracting

13:31 <RX14> hmm you typically only have 1 file of failing tests though

13:31 <RX14> it's easy enough to ^C and change the command to run only 1 file

13:32 <jokke> what do you mean by ^C?

13:35 <RX14> ctrl-C

13:35 <RX14> quit

16:09 <manveru> can someone tell me how to write this these days? https://github.com/umurgdk/haydari/blob/master/src/haydari/parser.cr#L68

16:09 <manveru> i'm getting "undefined constant U" there

16:10 <Papierkorb> manveru: That U is not from the class, right? use `forall`: `def +(other : Parser(U)) forall U`

16:11 <Papierkorb> Hope I got it right *cough*, didn't need to forall a generic type yet

16:11 <manveru> looks like it's ok

16:11 <manveru> trying to fix the lib for current crystal

16:18 <RX14> manveru, do you need that U? I think just leaving it at Parser without the generic would work

16:18 <Papierkorb> it should

16:18 <manveru> hmm yeah
