<HarrisonB> Does method resolution w.r.t. overloading get resolved at runtime or compile time?
<FromGitter>
<fusillicode_twitter> @HarrisonB I think at compile time but I'm not quite sure about it ๐
<FromGitter>
<bew> @dscottboggs_gitlab since last release, yes if i remember correctly
<FromGitter>
<bew> indeed, there's a dynamic dispatch step in this case, but all methods are still checked at compile time

<JBreniac_twitter> Looking for a way to use (or easily implement) PHP's session feature (session_start() + $_SESSION["myvar"]). Any clue ?
<FromGitter>
<JBreniac_twitter> I mean, without using a full blown framework like Kemal or Amber...
<FromGitter>
<j8r> Kemal isn't the same bloat level as Amber...
<FromGitter>
<JBreniac_twitter> Right now Crystal default library gave me anything I need, I just need to figure out how to implement a simple session system in Crystal for user login stuff and my app is finished
<FromGitter>
<JBreniac_twitter> It's a small web site with low traffic, nothing life critical
<FromGitter>
<JBreniac_twitter> So using Amber was overkill
<FromGitter>
<JBreniac_twitter> And it was a way to learn Crystal in the process
<FromGitter>
<bararchy> @JBreniac_twitter does the app you're making is for learning purposes only? or do you intend to actually use it ?
<FromGitter>
<JBreniac_twitter> both actually
<FromGitter>
<bararchy> The I woulnd't recommend you do re-implement things like Session handeling as those are security + functionality, instead better to use `Kemal-sessions` or something similar
<FromGitter>
<JBreniac_twitter> it's a direct port of my PHP showcase website
<FromGitter>
<JBreniac_twitter> there is not sensitive data in it

<fusillicode_twitter> Hi guys, here I am for my today problem :( โ I'm trying to work with this shard but unfortunately I'm getting this exception whenever I try to perform a `find` :( โ โ ``` code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5bb35d821c100a4f291c39ec]
<FromGitter>
<fusillicode_twitter> I've already skimmed though the issues but I wasn't able to find anything interesting
<FromGitter>
<bararchy> @JBreniac_twitter Which `shard` ?
<FromGitter>
<fusillicode_twitter> @JBreniac_twitter sorry for the missing link :(
<FromGitter>
<bararchy> oh, not the same twitter user hahah @fusillicode_twitter
<FromGitter>
<fusillicode_twitter> @bararchy what have I done? ๐ฐ
<FromGitter>
<bararchy> @fusillicode_twitter I would say `File not open for writing` means that either `mongo` isn't up, or, you have no permissions to write to the unix socket (though that would have raised a differnt error)
<FromGitter>
<bararchy> @fusillicode_twitter You have done nothing wrong, I mistakenly tagged the wrong user when answering to you
<FromGitter>
<bararchy> Giving it a sec more thought, I would guess that it tries to open a file and can't open it for writing, maybe it's missing or being deleted? can you give the actual code making this error ?
<FromGitter>
<fusillicode_twitter> > @fusillicode_twitter You have done nothing wrong, I mistakenly tagged the wrong user fffiuuu I was already panicking...I feared I had broken some rules about asking about issues/problems ๐
<FromGitter>
<fusillicode_twitter> @bararchy regarding the error you're right, but the mongo I'm connecting to is actually a remote instance & the broken code is running from a docker container run from the latest crystal image, i.e. 0.2.6
<FromGitter>
<fusillicode_twitter> As far as I can guess it seems that the problem is somehow related to the logger ๐ค
<FromGitter>
<bararchy> Yeha, my fear, Maybe the docker don't have permissions to open sockets? in Linux sockets are files, and this error might indicate it can't do that
<FromGitter>
<bararchy> can you try the same code outside of the docker ?
<FromGitter>
<fusillicode_twitter> You're totally right, let me check
<FromGitter>
<fusillicode_twitter> Ok it seems that locally I don't get the error
<FromGitter>
<fusillicode_twitter> The strange thing is that even without the errore I can't get any result from the query
<FromGitter>
<bararchy> @fusillicode_twitter But maybe that's just a SQL error, maybe wrong syntax? try a `SELECT *` kind of query
<FromGitter>
<fusillicode_twitter> well the `collection.find()` method doesn't seem to accept nothing more than a BSON object instance ๐ค
<FromGitter>
<fusillicode_twitter> I think that I need to find another solution to my problem and put the interaction with a mongo aside for the moment
<FromGitter>
<fusillicode_twitter> but that's really sad :(
<FromGitter>
<fusillicode_twitter> anyway thanks a lot for the support @bararchy ๐
<FromGitter>
<bararchy> ๐ you can use MySQL ;) or postgres
<FromGitter>
<fusillicode_twitter> well yeah but unfortunately right now my options are a mongo or an s3 file XD
<FromGitter>
<fusillicode_twitter> I just need to save a timestamp in case of the success of an little ETL task that will run at scheduled intervals

<fenicks> > I have this error on CentOS7 with libssl, the installed version is libssl.so.1.0.2 and crystal program are looking for 1.1 : `error while loading shared libraries: libssl.so.1.1` โ How can I specify the correct version ? Is that an issue with the detection macro for the ssl version โ โ To bypass this issue on CentOS7, I run run my program inside a crystal docker container wich is Debian or Ubuntu.
<FromGitter>
<dscottboggs_gitlab> @fenicks oh good, you figured it out. That's how I figured you would have to do it, but that won't work for every use case. Unfortuanately that's the sort of thing you kinda have to expect from something that's still using a patched kernel 2.* haha
<FromGitter>
<dscottboggs_gitlab> especially when trying to use soemthing so new
<FromGitter>
<j8r> better to use reproducible environments, easily done with Docker. Then, compiling it statically to bypass this shared libraries issues across distributions
<FromGitter>
<dscottboggs_gitlab> that's a good solution
<FromGitter>
<fenicks> @dscottboggs_gitlab Yep, thanks for the tip
<FromGitter>
<fenicks> @j8r Yep, most of the time static compilation is Ok but in this case it doesn't work because of the gap between linux distributions on LibSSL version and shared library naming
<FromGitter>
<j8r> @fenicks for static compilation, I mean on the recommended system, Alpine Linux
<FromGitter>
<j8r> Anyway the error is legit, we don't always wan't static linking
<FromGitter>
<fenicks> @j8r Ah, ok. Agreed.

<HarrisonB> i asked this last night, but i just wanted to clear this up
<FromGitter>
<mverzilli> @HarrisonB when there's more than one plausible target for the call, it's performed at runtime
<FromGitter>
<mverzilli> if there was only one valid implementation of `foo` that worked with `a`, it'd be static
<FromGitter>
<HarrisonB> Even in cases of inheritance?
<FromGitter>
<HarrisonB> Is this in the docs?
<FromGitter>
<mverzilli> what do you mean with "in cases of inheritance"? would you adapt your example? other than some funkiness with generics I think it works as you'd expect
<FromGitter>
<HarrisonB> I guess my main experience with static typing is from Java
<FromGitter>
<HarrisonB> where method resolution (in cases of overloading) exclusively depends on the static type
<FromGitter>
<HarrisonB> e.g. if you have a `Parent` and `Child` class, if there's are two methods, e.g. one taking a `Parent` param & one taking a `Child` param, the one matching the static type will get called, (even if the type at runtime is more specific)
<FromGitter>

<bajro17> with regex is it possible to move on next one instead use position to actually move on next match

probably possible, but i don't quite understand what you're saying
<FromGitter>
<vladfaust> This should be memed too

<geolessel> I feel like I'm getting *really* close to figuring this out, but can't get it done. I'm attempting to create a CLI app in Crystal that on a certain keypress takes you to your $EDITOR then returns back to the program. I've been able to use Process.exec to get vim (my $EDITOR) running but when I quit vim, it quits my crystal program. This makes sense since the docs say Process.exec *replaces* the current
<FromGitter>
... process. Is there any way to temporarily replace it and then go back to it?
<FromGitter>
<dscottboggs_gitlab> Process.run
<FromGitter>
<dscottboggs_gitlab> right?
<FromGitter>
<geolessel> When I try that, vim doesn't take over the screen and seems to auto-exit
<FromGitter>
<dscottboggs_gitlab> yeah, I just was looking at the docs and noticed something tricky about that
<FromGitter>
<dscottboggs_gitlab> Process.run *without* a block gives the process `/dev/null` instead of the standard pipes. All the other versions (`#new`, `#exec`, and `#run` when run with a block) give the process the standard streams by default
<FromGitter>
<dscottboggs_gitlab> try running it with `output: STDOUT` etc?
<FromGitter>
<geolessel> oooh, getting closer
<FromGitter>
<geolessel> I think that may do the trick. My CLI app uses ncurses and when the process returns to it from vim the screen is all sorts of messed up. That may just be a ncurses thing though.
<FromGitter>
<dscottboggs_gitlab> nice
<FromGitter>
<dscottboggs_gitlab> hate that when ncurses ruins your terminal haha
