<kaukas_gitlab> I upgraded to 0.26, and now my `crystal spec` does not output dots one-by-one but all at once, when tests finished. This is on latest mac. Is that something that others experience as well?
<oprypin>
kaukas_gitlab, i think i'm getting that as well on linux
<oprypin>
certainly worth reporting

<schoening> What am I doing wrong here? Just testing out. I need to convert objects inside an array into json eventually
<FromGitter>
<asterite> `require "json"`
<FromGitter>
<schoening> Hahaha omg :) Thanks!
<FromGitter>
<schoening> Sorry but I have a second question that I cant figure out.. ⏎ https://play.crystal-lang.org/#/r/4rpn ⏎ Trying to #to_json an array here... Why is that not possible?
<oprypin>
@schoening, well again, require "json" but then also Group has no defined conversion to json
<FromGitter>
<schoening> Thanks for the help @asterite @oprypin now I can generate some large json data that had my node.js choking :D

<Groogy> Finally on my way home again
<FromGitter>
<Groogy> Doing some summer cleaning on my webserver and I know there's a bunch of web developers here, what blog app is best to use these days? Or interesting, best is probably still wordpress
<FromGitter>
<schoening> Ghost or Medium are good too. Nothing wrong with Wordpress unless you drink all of the hipster cool aide like I used to
<FromGitter>
<Groogy> Haha I'm not, I'm just going through all of the potentials in softaculous right now
<lvmbdv>
> not static site generators
<lvmbdv>
ewwww
<lvmbdv>
hugo is pretty rad groogy
<oprypin>
> not reinventing your own wheel
<lvmbdv>
yes you can write your own static site generator as well
<FromGitter>
<schoening> if I ever start blogging on either software or self development then I would take Medium. Its a nice platform and I already read 80% of articles from there.
<lvmbdv>
> you visited our site 3 times, please sign up
<FromGitter>
<Groogy> it's not for actual blogging though

<FromGitter>
<stronny> good evening. suppose I have aa finalize
<FromGitter>
<stronny> the docs say I shouldn't allocate anything, however how do I get around that?
<oprypin>
you don't
<FromGitter>
<stronny> Time is a struct, so should live on stack, but String is a ref, right?
<oprypin>
give an example and maybe you'll get some alternative
<oprypin>
or explain what you actually want to do
<FromGitter>
<Groogy> Are you trying to figure out when objects are being deleted?
<FromGitter>
<Groogy> you can have a look at my Trashman
<FromGitter>
<Groogy> most probably you want to store away the time and inspect it later
<FromGitter>
<stronny> I just think it's neat to have a debug level runtime logging for GC is all
<FromGitter>
<Groogy> also why are you mixing concenation and #{expr}?? just use "#{expr} #{and more expr}"
<FromGitter>
<stronny> this is just a pseudocode off the top if my head
<FromGitter>
<Groogy> Then you probably want to use Trashman
<FromGitter>
<Groogy> it records everything if you turn it on as long as you mixin the module
<FromGitter>
<stronny> My question is more about memory model though ⏎ Is there a way to use a String on stack?
<FromGitter>
<Groogy> no it's an object
<FromGitter>
<Groogy> you would have to implement it yourself using a struct and StaticArray to mimic a normal String, but it would mean it would be copied everywhere
<FromGitter>
<Groogy> and it's size would be fixed as well
<FromGitter>
<schoening> ri9e
<FromGitter>
<schoening> oi.. cat across keyboard. I thought people made that up
<FromGitter>
<stronny> shame we don't have a StaticStrinig then =(
<FromGitter>
<Groogy> well you can always implement it
<FromGitter>
<Groogy> but you could solve that with macros
<Yxhuvud>
well, string constants are saved in the DATA area, no?
<FromGitter>
<Groogy> since the macro can read string literals
<FromGitter>
<Groogy> ah yeah but it would be a String object
<FromGitter>
<stronny> can I just allocate a buffer and reuse it with Time#to_s(io)?
<FromGitter>
<Groogy> and behave like one, after you've done str = "hello world", str is a String object
<oprypin>
stronny, no matter what you do, time.to_s probably does its own string allocations
<oprypin>
you sshould try, though
<oprypin>
`time.to_s(STDOUT)`
<oprypin>
i suspect it will not work but that will be your confirmation
<lvmbdv>
good project name groogy

<Groogy> Also hmm I'm sort of curious, if I want to use Crystal stuff on my server, let's say a Kemal app, all I need is to have the compiled executable, the executable won't depend on anything weird right?
<oprypin>
Groogy, only some libraries that every distro has
<oprypin>
and you likely cant move the executable from a different distro
<FromGitter>
<Groogy> Yeah and I can probably get the server admin to install things for me
<FromGitter>
<Groogy> I've gotten him to do it before so
<oprypin>
O_o
<FromGitter>
<Groogy> ManuFrog is a great server host
<FromGitter>
<Groogy> had my server there for 10 years now
<FromGitter>
<Groogy> for private use at least
<oprypin>
just looked it up, seems like the worst deal that i've seen in a long time
<FromGitter>
<Groogy> Anyway I'm on the edge of starting another project ;^-^
<lvmbdv>
it will groogy
<lvmbdv>
libevent, libyaml, many things
<oprypin>
nvm i thought it was 18 USD
<lvmbdv>
static compiling is not ready yet
<lvmbdv>
(i think
<lvmbdv>
)
<FromGitter>
<Groogy> Ah no it's a Swedish webhost
<FromGitter>
<Groogy> so it's crowns
<FromGitter>
<Groogy> hmm gonna experiment when I get home, see if I can get it to run a simple hello world output
<lvmbdv>
you can list the linked libraries with `ld`
<Yxhuvud>
I mean, if you don't expect to have any load there are plenty of free hosting. heroku has a free tier, etc
<lvmbdv>
yeah there is a crystal webpack for heroku too
<FromGitter>
<Groogy> anyway train almost at end station, time to log out, cya!

<vlazar> I'm updating a small GraphQL service which worked in Crystal 0.24 to Crystal 0.26. The https://github.com/ziprandom/graphql-crystal wasn't working in 0.25 before, now it's fixed and my service appears to work in 0.26 now. ⏎ ⏎ However when I try to build service in release mode with `build --release` I get this weird error: ⏎ ⏎ ``` code paste, see link``` [https:/
<FromGitter>
<vlazar> @valamorgon on OSX it's `brew uninstall crystal` and then `brew install <link to raw formula on github>`
<oprypin>
stronny, no it's not safe to assume because it is not part of the functions API / documentation
<FromGitter>
<stronny> so you're saying it can change and I shouldn't depend on a particular observation?
<FromGitter>
<valamorgon> @vlazar any idea on ubuntu? I try sudo apt install crystal=0.25.1-0 or sudo apt install crystal=0.25.1-1 but it says: E: Version '0.25.1-0' for 'crystal' was not found
<oprypin>
stronny, yeah i guess that's what i'm saying. though it's only theoretical.
<oprypin>
what i really mean is that you probably shouldn't be messing with any of this
<FromGitter>
<stronny> so what would you recommend? wrap strftime?
<oprypin>
stronny, do not try to hack your way around the limitation of no allocations
<oprypin>
do not use finalizers for anything important
<FromGitter>
<stronny> writing a debug log is hardly important, though nice to have
<oprypin>
valamorgon, have you checked in local cache perhaps? do you see anything in `ls /var/cache/apt/archives/*crystal*`
<FromGitter>
<stronny> so you suggest storing the information and processing it after the finalizer is done right?
<FromGitter>
<stronny> I suppose it can work, though it would require a more complex logic. I feel it will just move a dangerous piece from one place to another though, because to store something you might need to realloc after all.

Hey, what was the solution from the other day to convert an Array of e.g. [1,2,3] into a Hash of [1 => true, 2 => true, 3 => true] ?

<bcardiff> @vlazar you can use darwin .tar.gz files from github releases. those binaries will use llvm 3.9, but you can downgrade to any crystal version. ⏎ ⏎ Other alternative is to use docker images.

<j8r> @Groogy you can statically link your Crystal program, and the only send the binary to any Linux system and that's it
