15:31 <sixecho> anyone can recommend a ruby gem that facilitates interactive prompts in the terminal - and also something that lets you choose from a list (using arrows/etc)

15:31 <rapha> boss: "could you quickly repair this zip files". me: "sure, let me just quickly brush up on my hollywood bullshit bingo talk skills!"

15:43 <sixecho> caleb: excellent, thanks!

15:55 <nakilon> cool, is it better than tty-prompt?

15:56 <nakilon> I'm currently lazily making a gem that does a dialog where you are supposed to configure multiple options

17:30 <rg> tty-* gems i've used were quite buggy but been a while

17:32 <weaksauce> cli-ui is backed by shopify so i'd assume it has some decent engineering behind it

17:32 <nakilon> I didn't like something about it, either some API decision or an update I saw when was using it the first time; but didn't know any alternatives

17:33 <nakilon> I wonder how to test it

17:37 TomyWork has quit [Remote host closed the connection]

17:37 <weaksauce> nakilon perhaps some of their own tests would inform a bit

17:38 <nakilon> yeah looks painful though with those characters https://github.com/Shopify/cli-ui/blob/master/test/cli/ui/progress_test.rb

17:39 <weaksauce> fundamental complexity of the terminal that

17:39 <nakilon> however unit tests aren't the same as tests one would make for his program that uses this lib

17:39 vaillancourtmax has joined #ruby

17:40 <weaksauce> maybe someone in https://github.com/Shopify/cli-ui/network/dependents?package_id=UGFja2FnZS00MTA3NzkxNw%3D%3D is testing

19:13 <nakilon> I hate when I do '| head' and it says in `write': Broken pipe @ io_writev - <STDOUT> (Errno::EPIPE)

19:13 <nakilon> is there any neat way to avoid this?

19:14 <leah2> doesnt happen here oO

19:15 billionaire has quit [Quit: Connection closed for inactivity]

19:16 <leah2> does adding Signal.trap("SIGPIPE", "SYSTEM_DEFAULT") help?

19:18 <nakilon> didn't try

19:18 <nakilon> simple way to reproduce: ruby -e '1000.times{ puts rand }' | head -10

19:20 <vaillancourtmax> Indeed, that's a broken pipe for me too

19:20 <weaksauce> yeah i mean that makes sense

19:20 <vaillancourtmax> However, this works just fine: ruby -e '1000.times{ puts rand }' | cat | head

19:21 <vaillancourtmax> Something about the output straight from Ruby breaks head

19:22 <rg> works fine for me on ruby3

19:22 fmccann has quit [Quit: Exeunt!]

19:22 <rg> breaks on ruby2

19:24 <leah2> vaillancourtmax: well cat buffers more

19:24 <leah2> hm, maybe it changed in ruby3

19:24 <rg> looks like it

19:24 <leah2> perl quits silently too

19:25 <vaillancourtmax> Yeah indeed leah2, my mistake
