00:11 <Fuzai> Hello, does anyone know of a library for Crystal that allows one to connect to a ScyllaDB cluster?

00:17 <FromGitter> <Blacksmoke16> hmm, not that i know of. Also dont see any in any of the shard aggregation sites either :/

13:14 <FromGitter> <noaheverett> Fuzai: could you use a Cassandra driver (https://github.com/kaukas/crystal-cassandra) since Scylla is (was?) based on Cassandra or do they require their own driver now?

17:27 <yxhuvud> could also be worth the effort asking the scylladb company if they know of anything

19:29 <FromGitter> <sergiotapia> Hello, new to Crystal just did a crystal init app myapp and ran `crystal spec` and I get this error. What am I supposed to install locally on my dev machine for this to work?

19:29 <FromGitter> <sergiotapia> `/usr/bin/ld: cannot find -lpcre (this usually means you need to install the development package for libpcre): No such file or directory`

19:29 <FromGitter> <Blacksmoke16> how did you install crystal?

19:30 <FromGitter> <sergiotapia> I used asdf

19:30 <FromGitter> <Blacksmoke16> on `1.6.1` yea?

19:30 <FromGitter> <Blacksmoke16> basically you just need to make sure you have `libpcre` installed

19:31 <FromGitter> <sergiotapia> `sudo apt-get install libpcre` that package doesn't seem to exist. What do I need to install?

19:31 <FromGitter> <Blacksmoke16> https://github.com/asdf-community/asdf-crystal/issues/29

19:31 <FromGitter> <sergiotapia> thanks, that worked fine

19:32 <FromGitter> <Blacksmoke16> not sure why installing libevent fixes this given it clearly says pcre but who am i to argue 😅

19:33 <FromGitter> <sergiotapia> to be clear, I had to install `libpcre3-dev` per that github thread, and it fixed the issue

19:33 <FromGitter> <Blacksmoke16> ahh 👍 that makes more sense :)

19:34 <FromGitter> <Blacksmoke16> i never used asdf, but ideally that would be installed when you install crystal itself as its a dependency

19:38 <FromGitter> <sergiotapia> cool. I'm going to rewrite this little script from Nim to Crystal and see how Crystal feels. https://github.com/sergiotapia/ekeko/blob/master/src/tiktok.nim

19:38 <FromGitter> <Blacksmoke16> sounds like a plan

20:58 <FromGitter> <sergiotapia> I can't seem to find the docs for this system call: https://philstories.medium.com/crystal-lang-execute-shell-command-3afe38c0a293

20:58 <FromGitter> <sergiotapia> Trying to invoke `yt-dlp` from my Crystal app

20:59 <FromGitter> <Blacksmoke16> https://crystal-lang.org/api/toplevel.html#system%28command%3AString%2Cargs%3Dnil%29%3ABool-class-method

20:59 <FromGitter> <sergiotapia> thank you!

20:59 <FromGitter> <Blacksmoke16> tho if you need more control, can use https://crystal-lang.org/api/Process.html#run%28command%3AString%2Cargs%3Dnil%2Cenv%3AEnv%3Dnil%2Cclear_env%3ABool%3Dfalse%2Cshell%3ABool%3Dfalse%2Cinput%3AStdio%3DRedirect%3A%3AClose%2Coutput%3AStdio%3DRedirect%3A%3AClose%2Cerror%3AStdio%3DRedirect%3A%3AClose%2Cchdir%3APath%7CString%3F%3Dnil%29%3AProcess%3A%3AStatus-class-method

21:02 <FromGitter> <sergiotapia> hm... how would I capture the output of the system call. I need to capture the pretty json `yt-dlp` returns

21:05 <FromGitter> <Blacksmoke16> prob something like:

21:05 <FromGitter> <Blacksmoke16> ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=636038a0dcbf067fdcbe40b4]

21:06 <FromGitter> <sergiotapia> interesting, `Unhandled exception: Error executing process: './downloads/youtube': Permission denied (File::AccessDeniedError)` my code doesn't seem to have permission to write to the folder? yet my code with `system` works fine

21:06 <FromGitter> <Blacksmoke16> oh?

21:07 <FromGitter> <Blacksmoke16> can you share the code so far?

21:07 <FromGitter> <sergiotapia> @gewor

21:07 <FromGitter> <sergiotapia> @Blacksmoke16 https://pastebin.com/Mt6XBM0c

21:09 <FromGitter> <Blacksmoke16> oh, do you just want to putout the process output to your terminal?

21:09 <FromGitter> <Blacksmoke16> if so, you can just do like `output: :inherit`

21:09 <FromGitter> <Blacksmoke16> same with `error` and it'll use your tty

21:10 <FromGitter> <Blacksmoke16> `system` just returns a bool if it is successful or not, so it prob also failed, just not with an exception like that

21:10 <FromGitter> <sergiotapia> No i need to capture the pretty json response of yt-dlp

21:11 <FromGitter> <Blacksmoke16> to use at a later point in the code?

21:11 <FromGitter> <sergiotapia> Yes parse the json and grab two values

21:12 <FromGitter> <Blacksmoke16> okay, then yea `IO::Memory` is what you want

21:15 <FromGitter> <Blacksmoke16> prob could optimize things a bit when its all said and done, but it'll be good enough :P

21:16 <FromGitter> <sergiotapia> Im stuck with this permission error thing lol

21:19 <FromGitter> <Blacksmoke16> i assume the user you're running the program with has access to run it?

21:20 <FromGitter> <Blacksmoke16> also make sure the file exists where you expect it to, and is executable

21:20 <FromGitter> <Blacksmoke16> e.g. https://crystal-lang.org/api/File.html#executable?(path:Path|String):Bool-class-method

21:26 <FromGitter> <sergiotapia> I'm a dummy lol copy pasted the wrong thing works fine

21:30 <FromGitter> <Blacksmoke16> that would do it :P

22:07 <FromGitter> <sergiotapia> Done! https://pastebin.com/3pPsjJ1d ⏎ ⏎ Is this idiomatic? any changes you recommend as i'm new to crystal

22:11 <FromGitter> <sergiotapia> dead simple deploy with `crystal build --release --no-debug` care went into the dev ux love it!

22:13 <FromGitter> <Blacksmoke16> I have some ideas, but am currently afk so can look when I get back if no one else jumps in before that

22:58 <FromGitter> <vgramkris> Does flock_exclusive with default blocking=true yield to another spawn when it is being blocked (seems it is not yielding but want to confirm)?

23:54 <FromGitter> <Blacksmoke16> @sergiotapia try this: ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=6360602e27f328266d658dd7]

23:54 <FromGitter> <Blacksmoke16> tho tbh, i'd prob just use bash for this :P
