09:45 <holst> How does the Atom thing work? How can I pass a reference to an Atomic to a spawned code block?

09:45 <holst> https://play.crystal-lang.org/#/r/cx0w

09:45 <holst> here the "total" is shown as 0 even after the call, but obviously, I want it to show 4

11:19 <FromGitter> <asterite> Atomic is a struct so it's passed by value. You need to use a class that holds that atomic, and then it will work.

13:21 <FromGitter> <jrei:matrix.org> A pointer can work too, but unsafe

16:10 <holst> https://play.crystal-lang.org/#/r/cx2f I am struggling with how to define a method that I can use and where I define my "main" code in a CLI app

16:10 <holst> in Python I know about if __name__ == "__main__" or __main__.py

16:11 <holst> but I think a FAQ like discussion on this would be great. I might even volonteer to do a cookbook "Crystal Language for Pythonistas" ;-)

16:12 <FromGitter> <Blacksmoke16> you'd prob want to use two files

16:13 <FromGitter> <Blacksmoke16> one is like the "library" code and the other is the entrypoint to the CLI. I.e. that requires the library code, sets up the option parser logic, etc

16:15 <FromGitter> <Blacksmoke16> there are also some shards out there to help with building CLIs if you want to go that route

16:21 <holst> makes sense; that would be app/{__init__,app}.py and app/__main__.py to run the app

16:21 <FromGitter> <Blacksmoke16> https://github.com/Blacksmoke16/oq/tree/master/src has an example

16:23 <holst> Great example thanks

21:39 <FromGitter> <descholar-ceo> Hello here, today is my first day trying out crystal, do we have a tool like *irb* in crystal?

21:40 <FromGitter> <Blacksmoke16> https://crystal-lang.org/2021/12/29/crystal-i.html

21:46 <FromGitter> <descholar-ceo> Thank you, but that seems like it works for someone who's going to install crystal so he needs to be careful while compiling crystal, what about ? I have already installed and compiled crystal, but didn't provide that flag, how can I integrate it now?

21:46 <FromGitter> <Blacksmoke16> theres a shard `icr`, but its slightly a hack

21:46 <FromGitter> <Blacksmoke16> so will have to wait for proper `crystal i` support, or just leverage a `test.cr` file for now

21:47 <FromGitter> <moe:busyloop.net> icr works fine for me, i use it to try out simple expressions almost every day

21:48 <FromGitter> <descholar-ceo> how can I install `icr` then?

21:49 <FromGitter> <moe:busyloop.net> on osx `brew install crystal-icr`

21:49 <FromGitter> <descholar-ceo> I use linux mint

21:49 <FromGitter> <moe:busyloop.net> don't know about other os'es

21:51 <FromGitter> <Blacksmoke16> https://github.com/crystal-community/icr#installation

22:00 <FromGitter> <descholar-ceo> Thank you

22:00 <FromGitter> <descholar-ceo> I have it working for now

22:05 <FromGitter> <Blacksmoke16> 👍

22:11 <FromGitter> <Blacksmoke16> `crystal eval` and `crystal play` are also options

22:20 <holst> postmany v0.3.0 released! ;-)

22:20 <holst> https://github.com/cli-tools/postmany

22:20 <holst> Blacksmoke16: thanks for the help, ;-)

22:21 <holst> It's possible to use that tool to slam lots of pre-baked API calls to a REST endpoint or to just upload a bunch of files to S3/Azure Blob storage

22:53 <FromGitter> <Blacksmoke16> holst: https://github.com/cli-tools/postmany#installation

22:53 <FromGitter> <Blacksmoke16> btw, the `--production` flag doesn't also include `--release`

23:11 <holst> --production: Runs in release mode. .. the documentation wasn't crystal clear on this, pun intended

23:12 <FromGitter> <Blacksmoke16> Just means it doesn't install dev dependencies

23:12 <holst> run: shards --production build --release --static

23:12 <holst> I was actually including both in the build script, but I will update the README as well

23:13 <holst> should I include --no-debug?

23:13 <FromGitter> <Blacksmoke16> 👍

23:13 <FromGitter> <Blacksmoke16> If you want, would make the binary smaller, but also the strack trace less helpful

23:27 <holst> I am anyway running strip on it, which isn't a really good idea given how unstable / buggy this is right now

23:27 <holst> But I did just put this tool into my integration tests pipeline so I am bound to find a lot of corners (I just found a bug that way)

23:28 <FromGitter> <Blacksmoke16> Probably should write some tests too if possible
