<drosehn> You could use something like stunnel to setup the ssl-connection. (I suspect that mysql wants ssl connections, not ssh sessions).

<girng> i was curious what's the fastest and most performant way to replace words in a string? gsub?

<Blacksmoke16> anyone have an example of using the `path` option in `shard.yml`?
<FromGitter>
<girng> Int8 compiles, but UInt8 gives that error before compiling. `Int8` and `Bool` give the `not supported read` when the query is executed

<straight-shoota> @7sedam7 There is an issue for mysql over tls: crystal-lang/crystal-mysql#68
<FromGitter>
<vladfaust> @girng it's a nice idea to dive into the MySQL driver code and maybe extend it
<FromGitter>
<vladfaust> I mean, it's not that hard
<FromGitter>
<vladfaust> Had to do some extensions both to crystal-pg and redis to make my ideas work :)

<FromGitter>
<Willyboar> Well done! Congrats @straight-shoota. You are very active and you deserve it.
<FromGitter>
<straight-shoota> Thanks =)
<FromGitter>
<7sedam7> > A workaround would be to terminate the ssl connection to a local socket and connect to that. That's what I've done once or twice (not with crystal-db though). ⏎ Hei @straight-shoota can you explain how could I do it in crystal?
<FromGitter>
<straight-shoota> It could probably be done by using `IO.copy` to bidirectionally pipe between an SSL and local TCP socket. ⏎ But implementing that yourself is probably not the best option. I suppose there are a lot of edge cases to account for in order to keep the connection going. Ensuring fault tolerance can be very tricky.
<FromGitter>
<j8r> @7sedam7 or you can open an SSH tunnel with `ssh -L`
<FromGitter>
<j8r> and connect to the database as it was in localhost
<FromGitter>
<straight-shoota> I'd rather use dedicated tool like `stunnel` or `ssh -L`
<FromGitter>
<straight-shoota> The latter requires login access on the target system
<FromGitter>
<proyb6> Let see how actively Crystal was installed from Homebrew? ⏎ 1,005 (30 days), 4,902 (90 days), 13,219 (365 days)
<FromGitter>
<Willyboar> no bad
<FromGitter>
<proyb6> I think it's not by unique installation
<FromGitter>
<Willyboar> It contains and upgrades?

<Blacksmoke16> so im working on request lifecycle events now, like `after_all`, etc
<FromGitter>
<Blacksmoke16> and wanted to get some feedback/thoughts
<FromGitter>
<Blacksmoke16> current plan is for the user to define a class method in their controller, add an annotation, and the event it should be called on, e.x ⏎ ⏎ ``` code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5c2a5d76babbc178b2087274]
<FromGitter>
<Blacksmoke16> this would trigger that callback on any request for any route defined in that controller class
<FromGitter>
<Blacksmoke16> also prob have a `actions` property on the annotation to limit the routes it gets executed on
<FromGitter>
<Blacksmoke16> or possibly make it execute on the class its defined in, OR children of that class

<Willyboar> @Blacksmoke16 where are you from. I am asking because the name Athena.
<FromGitter>
<Blacksmoke16> PA USA
<FromGitter>
<Blacksmoke16> Named based on the Greek god :p
<FromGitter>
<Willyboar> Yes i know. I am Greek :)
<FromGitter>
<Blacksmoke16> ;)
<FromGitter>
<Willyboar> i am waiting to test Athena ;)
<FromGitter>
<Blacksmoke16> go ahead, most things should be working on the `v0.1.0` branch
<FromGitter>
<Blacksmoke16> at least in regards to basic function and conversions and such
<FromGitter>
<Blacksmoke16> but deff not stable :p
<FromGitter>
<Blacksmoke16> syntax and stuff might change
<FromGitter>
<Blacksmoke16> and i dont have any docs written yet
<FromGitter>
<Willyboar> I am thinking about trying to write my own framework, or at least try.
<FromGitter>
<Blacksmoke16> give it a try, can be a fun project
<FromGitter>
<Willyboar> Yes, i think it would be. And i am thinking something different from the excisting frameworks.
<FromGitter>
<Blacksmoke16> oh?

<Blacksmoke16> what were you thinking @Willyboar ?
<FromGitter>
<kevinelliott> I’ve spent some time reading crystal source code this holiday :)
<FromGitter>
<Willyboar> well it’s to early to tell something @Blacksmoke16
<FromGitter>
<Blacksmoke16> ah, thought you already had an idea of what you would do differently
<FromGitter>
<Willyboar> yes i have but it is very general at the moment. I usual organizing a lot before i start something.
<FromGitter>
<Blacksmoke16> 👍 sounds like a plan
<FromGitter>
<Willyboar> 👍
<FromGitter>
<codenoid> so
<FromGitter>
<codenoid> will crystal become 1.0 in 2019 ?

<grahamnicholls> Am I in the right place - I want to ask about using globals in Crystal (which I'm hugely excited about(Crystal, not globals))? I posted on SO - not long ago - I'm an impatient old g*t, but was reading around and it seemed that this might be better. Thanks.
<FromGitter>
<Blacksmoke16> global variables?
<FromGitter>
<Blacksmoke16> they arent a thing
<FromGitter>
<grahamnicholls> PS Excited because Ruby is lovely, but seems to be dying in favour of the less expressive Python. Compiled Ruby seems like the perfect sweet spot.
<FromGitter>
<grahamnicholls> Well, they seem to be - but I might be misunderstanding modules.
<FromGitter>
<grahamnicholls> DO I post a code snippet here?
<FromGitter>
<grahamnicholls> (And I know it's not compiled Ruby, really, in case that's a terrible faux pas!)
<FromGitter>
<Blacksmoke16> sure, got a playground link?
<FromGitter>
<grahamnicholls> playground - is that codepen?
<FromGitter>
<Blacksmoke16> well it doesnt compile :P is that your question?
<FromGitter>
<grahamnicholls> YEah, I saw that - it does on my laptop - 2 secs ...
<FromGitter>
<grahamnicholls> I'm wondering about the global debug_mode
<FromGitter>
<Blacksmoke16> well thats a constant
<FromGitter>
<Blacksmoke16> so you wouldnt be able to change the value once you define it
<FromGitter>
<grahamnicholls> Is it - I'm able to write to it - give ma a couple of minutes to get it to compile ...
<FromGitter>
<Blacksmoke16> kk
<FromGitter>
<grahamnicholls> OK, sorry for the delay - what's there compiles, now.
<FromGitter>
<grahamnicholls> SO the idea is that if you run it with a "-d" on the command-line, it toggles the global debug_mode
<FromGitter>
<grahamnicholls> then your calls to the method debug_msg() actually do something, as opposed to simply returning.
<FromGitter>
<grahamnicholls> Ah but it isn't working as I expected, when I test with solver -d 1 2 3 , it works, but without the -d it still prints the debugs, which fits with what you expect. false != nil - let me fix that ...
<FromGitter>
<Blacksmoke16> would have to relink it
<FromGitter>
<Blacksmoke16> each run is diff url
<FromGitter>
<grahamnicholls> OIC, ta - will do - (and false is false, so ignore last comment).
<FromGitter>
<Blacksmoke16> maybe check that out if you doing CLI stuff
<FromGitter>
<grahamnicholls> I'm not a fan of optionparsers, TBH. IMO, thy obfuscate, when I want a simple:
<FromGitter>
<grahamnicholls> debug_mode=true if args.includes?("-d")
<FromGitter>
<Blacksmoke16> as you wish
<FromGitter>
<Blacksmoke16> that could just be `debug_mode = args.includes? "-d"`
<FromGitter>
<grahamnicholls> that sets a global (and I know that they are (not unreasonably) frowned upon, but I think this is a useful example, and TBH whether I use an optionparser or not, I'd still like to know if I'm being too "old school"
<FromGitter>
<grahamnicholls> So even with optionparser, I'd want to set the global "debug_mode", so that the code can have debug_msg calls which either (normally) do nothing, or when -d is given , print whatever theyre told to.
<FromGitter>
<grahamnicholls> And yes, I prefer your syntax there, thanks - seems more Ruby/Crystal like code.
<FromGitter>
<grahamnicholls> Still have the question - is that a "global" (debug_mode). If it is, should I be taken out and shot for using it, because there's a better way?
<FromGitter>
<Blacksmoke16> its global in the sense its in the top level namespace
<FromGitter>
<Blacksmoke16> but its not actually a global variable
<FromGitter>
<Blacksmoke16> better way to handle this imo would be have a like config class, and use class vars
<FromGitter>
<Blacksmoke16> then if you get that flag switch the var there to true
<FromGitter>
<grahamnicholls> Hmmm. This is exactly what I was wondering.
<FromGitter>
<Blacksmoke16> or a struct
<FromGitter>
<grahamnicholls> My objection is that my code (and in C I'd use a struct for this) seems more readable than having a config class (but of course, things always grow).
<FromGitter>
<grahamnicholls> I'm not wedded to my opinion, though, which is why I'm here, really.
<FromGitter>
<Blacksmoke16> can use the record macro
<FromGitter>
<grahamnicholls> I wonder - I tend to use Ruby (and hopefully Crystal) mostly for what I'd have done in awk/sed/tr/bash/pipes, etc in the past. I love Ruby for it's expressive clarity - do you think I need to try to start being more Ruby/Crystal oriented, and get more into the idiom of both?

<grahamnicholls> Interesting - (I suspect that I'm not enough in the Ruby mindset- being an old C-programmer), but why do you say that, please?

<FromGitter>
<Blacksmoke16> While the syntaxes are similar they are separate languages
<FromGitter>
<Blacksmoke16> Does not map 1 to 1 to Ruby, best to take a step back and rethink how you plan to do something to take advantage of crystal
<oprypin>
yes, that's a nice way to put it
<FromGitter>

<grahamnicholls> So, is there a stype guid along the lines os the Python one, which I can read? Thanks.
<FromGitter>
<grahamnicholls> or even a style-guide, sorry. wrong glasses on.
<FromGitter>
<Blacksmoke16> my as well take advantage of the built in features of a language, esp if it makes something easier to see what is going on
<FromGitter>
<Blacksmoke16> but of course its all relative to what the project is
<FromGitter>
<Blacksmoke16> hmm, now to think of how i want to handle global before/after events
<FromGitter>
<Blacksmoke16> vs controller specific
<FromGitter>
<grahamnicholls> Simpler than debug_mode = args.includes? "-d"` ? I'm not convinced :-)
<FromGitter>
<grahamnicholls> As you say - depends somewhat on the project, but I'm persuadable - I'll look again at option_parser, thanks.

<j8r> I've read
<FromGitter>
<j8r> Previously, a language with coroutines that compiled in LLVM would have had to implement coroutines by hand. LLVM 4.0 adds support for representing coroutines directly in the compiler via new instructions in its intermediate representation (IR).
