<girng> btw, is there something like list($var, $var2) in crystal? i'm looking at https://crystal-lang.org/api/0.26.0/String.html#split%28separator%3AString%2Climit%3Dnil%2C%2A%2Cremove_empty%3Dfalse%2C%26block%3AString-%3E_%29-instance-method
<FromGitter>
<girng> oh wow NVM I just removed the brackets it works!!
<FromGitter>
<j8r> lol
<FromGitter>
<girng> man, parsing this nginx log is a PITA
<FromGitter>
<girng> they got `:`'s and spaces all over
<FromGitter>
<j8r> you can `line.squeeze(' ').split ' ', remove_empty: true`
<FromGitter>
<girng> wow that squeeze method is something else :D
<FromGitter>
<girng> i like it

<vladfaust> Saw Reddit post as well. I think it's time to stop. To stop creating drama an admit that Crystal is the best language on the table. I use it in production and it works flawlessly. It has a fast growing community, as seen on amount of projects at crystalshards and awesome-crystal. I tried to get back to Ruby recently after catching errors in Postgres driver (which is maintained by a person which doesn't use
<FromGitter>
... this driver in production, I guess), and found it impossible.
<FromGitter>
<girng> ^^ :D :D
<FromGitter>
<lukeajtodd> That’s some nice positivity :D
<FromGitter>
<vladfaust> Ruby is either a magic - ActiveRecord, Rails; or unnecessarily explicit (dry-rb, rom-rb), which doesn't give it a percent of performance compared to Crystal whatever
<FromGitter>
<vladfaust> I cant develop knowing that the code can fail at production in Ruby, so I need to write tests for every char I imprint into .rb files
<FromGitter>
<vladfaust> I'm damn serious
<FromGitter>
<vladfaust> Objectively, we have a old guy person which stands aside and grumbles what everything is wrong. You either invest into the project or it's ecosystem or keep your thoughts away, being positive. IMO it scares newcomers - the language author says he wouldn't use it real-life products. Seriously? 11k commits, 300 contributors, thousands bucks of donations, many companies already using it! Crystal won't just
<FromGitter>
... survive, it's already changing the game
<FromGitter>
<vladfaust> I wish I could phrase better, but I'm only good at writing the code (😏)
<FromGitter>
<vladfaust> Honestly, I'm trapped into Crystal. Just no other language brings me so much joy after 1.5 years of development. I wish there was a competitor with more web-development-ish views, because it looks like some of Crystal contributors don't use Crystal themselves in the web

<sdogruyol> @vladfaust that's well said
<FromGitter>
<sdogruyol> I agree with you that Crystal is changing the game already
<FromGitter>
<sdogruyol> Let's stop being pessimistic and get things done
<FromGitter>
<girng> LOL wow
<FromGitter>
<girng> just spent 10 minutes wondering wtf why nothing was happening, i had `def initalize` 😂
<FromGitter>
<girng> one thing that I think is very underrated is the crystal formatter. it helps me so much! makes my code so much more cleaner and readable. it would be insane to think what my code would look like without it xD
<FromGitter>
<vladfaust> Where can I read about new JSON field attributes?
<FromGitter>
<j8r> @girng there is also `initialize` vs `initialise`
<FromGitter>
<girng> @j8r lol
<FromGitter>
<girng> how can i detect if a command was run successfully? for example i'm doing `\`iptables -A INPUT -s xx.xx.125.84 -j DROP`\` in crystal and it works perfectly! howerver, what if the command somehow fails?
<FromGitter>
<valamorgon> I want to merge two wav files using crystal only. I can already do it in python like this code below and call it from crystal later
<FromGitter>
<valamorgon> but I want to do it using crystal only
<FromGitter>
<valamorgon> is it possible? do we have some audio library?
<RX14>
i'm not aware of one
<FromGitter>
<j8r> @girng yes you can, but you have to use `Process`
<FromGitter>
<girng> oohhh yeah
<FromGitter>
<girng> deja vu i remember asking this LOL
<RX14>
@valamorgon I recall the wave file format being pretty easy to parse though
<RX14>
so it'd probably pretty easy to write a library for it in pure crystal
<FromGitter>
<valamorgon> @RX14 I'm a little biased, I thought it will be hard to get it done without an audio library. But I will give it a try, thanks.
<FromGitter>
<girng> @valamorgon are you developing an audio mixer program or something in crystal? sounds cool
<FromGitter>
<valamorgon> @girng yes part of the software is something like LMMS. Project is in crystal but audio part is mostly nodejs and python
<FromGitter>
<schoening> Man.. the amount of data I have to send to the browser crashes the page, and it takes 10 seconds for crystall --release build to create that json from my classes. I dread to think how the performance of the MySQL + PHP of my client is going to be :D
<FromGitter>
<rishavs> Hi guys. what is the current state of Mongodb support in crystal? I noticed that we have a driver but it doesn't seems to be used much and is still in beta. Any anecdotes/reviews of what can I expect?
<FromGitter>
<straight-shoota> @girng take a look at `Process.run` and it's arguments
<FromGitter>
<girng> yeah was checking that .run, but i would need to put all my iptables arguments and separate them in an array. i really like just doing the entire command like a shell

<j8r> but it's more performant to directly call the binary instead of calling a shell that will call the binary
<FromGitter>
<j8r> `shell: false`
<FromGitter>
<girng> where is iptables binary at?
<FromGitter>
<girng> we can call binary directly? O_o
<FromGitter>
<yxhuvud> girng: use the `which` command in a terminal to find out what iptables binary you would use
<FromGitter>
<paulcsmith> This is one of the most common issues people run into in Crystal. It is because instance variables (in this case `status`) must be assigned to a local variable first, or use `try`. So you can do something like `store.status.try do |status|` and then check `status == "error"`
<FromGitter>
<paulcsmith> It would be awesome if Crystal gave you an error because it is nearly impossible to figure out without reading it in the docs or someone telling you
<FromGitter>
<paulcsmith> Luckily once you know about it it is pretty easy to workaround :)
<FromGitter>
<paulcsmith> Or actually you might need `store.try` since it appears to also be `nil`able
<FromGitter>
<paulcsmith> Also, I'd consider not allowing status and message to be `nil` and instead make *just* the store billable. So if the store is there, it always has a status and message
<FromGitter>
<rishavs> Thank you @paulcsmith You are a lifesaver!

<j8r> @girng In fact calling a shell will parse the arguments for you, you can do this too. take a string like `/sbin/iptables my args --options` and `split(' ')` and then `cmd = command[0]; args = command[1..-1`

rishavs: it means, make instances of this class respond to #location() and #location=(), giving or setting the value of @location, and make the data type be class Location, or nil

<Timbus> The doc is correct, you might have your test logic inverted
