<Blacksmoke16> assuming the width is 15
<FromGitter>
<Blacksmoke16> looked like https://crystal-lang.org/api/master/PrettyPrint.html#format(obj,io:IO,width:Int32,newline=%22%5Cn%22,indent=0)-class-method could do it but doesnt seem to do the breaking, or at least doesnt consider the string breakable
<FromGitter>
<tenebrousedge> I can't interpret the docs there
<FromGitter>
<Blacksmoke16> guess ill just do it myself then
<FromGitter>
<Blacksmoke16> open to better ideas tho :P
<FromGitter>
<tenebrousedge> I mean you could get most of the way there with `gsub` but it would be nasty to read
<FromGitter>
<tenebrousedge> oh um `each_cons`
<FromGitter>
<Blacksmoke16> its also unfortunate colorize uses `0` code to end its sequences
<FromGitter>
<Blacksmoke16> `hello ` is underlined and white, `foo` is underlined and red, ` bar` is white but no underline because `0` code clears all versus just the red color :/
<FromGitter>
<tenebrousedge> huh
<FromGitter>
<Blacksmoke16> prob is a bug, imma try and fix it
<FromGitter>
<tenebrousedge> that's really more than I want to know about ANSI escape codes
<FromGitter>
<Blacksmoke16> more than I knew earlier today too ha
<FromGitter>
<Blacksmoke16> porting some PHP code and noticed the formatted string's were diff
<FromGitter>
<Blacksmoke16> eh, i think ill just file it as a bug :p
<Andriamanitra>
in ruby you could do something like "puts str.scan(.{1,#{width}})", i couldn't figure out a way to make it as nice (nasty) in crystal though
<Andriamanitra>
i guess "puts str.chars.each_slice(width).map(&.join).join('\n')" is pretty much as good as it gets
<FromGitter>
<Blacksmoke16> can define styles for tags for use in output

<shootingfly> Hi, everyone. My clients are facing unfortunately an issue with the docker (When I upgrade the crystal version to 1.0.0). execute error: server error Hostname lookup for myscale.api.svc.cluster.local failed: System error
<FromGitter>
<shootingfly> Is there anyone who can help me? My customer upgraded a program to crystal 1.0.0 with .local domain. We use docker, crystal 1.0.0-alpine with `crystal build src/main.cr --release --static`.
<FromGitter>
<erdnaxeli:cervoi.se> that looks like a network error
<FromGitter>
<shootingfly> He rollbacked and retried many times between v0.35.1 and v1.0.0 ⏎ And for sure no issue with previous version v0.35.1 :/
<FromGitter>
<shootingfly> I have tested without .local domain in my machine. It is succeed.

<erdnaxeli:cervoi.se> he could try with crystal 1.0 not in an docker
<FromGitter>
<erdnaxeli:cervoi.se> to known if it comes from crystal 1.0 or from the alpine version that changed
<FromGitter>
<shootingfly> > to known if it comes from crystal 1.0 or from the alpine version that changed ⏎ ⏎ He is a java programmer and knows nothing about Crystal. I released a docker to him and he used it. But I have no .local domain.
<jhass>
shootingfly: is not -alpine an option to try? There's historically been some issues around alpine's libc and local/mdns resolution
<jhass>
I could imagine it's less about Crystal 1.0 and more a change in alpine version
postmodern has quit [Quit: Leaving]
<straight-shoota>
yeah, that's very unlikely to be a Crystal issue
<straight-shoota>
to verify, you can try an older alpine base image with Crystal 1.0. It won't be available in APK but you can just grab the generic linux tarball from Github.

<shootingfly> It is solved! Because I compiled it in general crystal, not alpine, and then run it in alpine.
<FromGitter>
<erdnaxeli:cervoi.se> oh, right
<FromGitter>
<shootingfly> Now I compiled it in alpine and ran it in alpine, then worked well.
<FromGitter>
<erdnaxeli:cervoi.se> btw, did someone suceeded to make a very small docker image for a crystal executable?
<FromGitter>
<erdnaxeli:cervoi.se> I tried to build it in static in alpin then copy it in a "FROM scratch" image, but it doesn't work
<FromGitter>
<erdnaxeli:cervoi.se> anyway, alpine is only 5Mo so that's ok
<FromGitter>
<Blacksmoke16> just use alpine
<FromGitter>
<erdnaxeli:cervoi.se> yep I does exactly that now
<FromGitter>
<Blacksmoke16> its still quite small and you get benefits of an OS/package manager and stuff
<FromGitter>
<erdnaxeli:cervoi.se> but I saw someone using FROM scratch with golang so I wanted to try
<FromGitter>
<Daniel-Worrall> In theory, it should work, but I don't think anybody has taken the time to investigate why some things don't
<straight-shoota>
it always depends on what you do...
<straight-shoota>
a hello world should certainly run in a scratch image, but when you use more things, there are more expectations about the program's environment

<erdnaxeli:cervoi.se> something with the PATH
<FromGitter>
<tenebrousedge> are you sure the file name is correct?
<FromGitter>
<erdnaxeli:cervoi.se> well yes, it was returned by `Process.find_executable`
<FromGitter>
<erdnaxeli:cervoi.se> btw self promotion time, this is about this project, which is a tool to skip sponsor segment on youtube videos playing on a chromecast: https://github.com/erdnaxeli/castblock
<FromGitter>
<tenebrousedge> can you paste how you're using `find_executable` ?
<FromGitter>
<oprypin:matrix.org> erdnaxeli (https://matrix.to/#/@erdnaxeli:cervoi.se): hmm the only explanation i could see for this is that /usr/bin/go-chromecast is a symlink pointing to a nonexistent destination

According to the dockerfile it is a file
<FromGitter>
<erdnaxeli:cervoi.se> using the same dockerfile, changing `FROM scratch` to `FROM alpin` works
