<exts> is crystal capable of executing/embedding itself like a scripting language?
<FromGitter>
<bew> well, it's not interpreted, so you'll need to compile the script, then execute it..
<FromGitter>
<exts> so there's no way to do that
<FromGitter>
<exts> wouldn't been cool, kind of like using lua inside c++
<FromGitter>
<exts> would've*
<FromGitter>
<bew> you can use lua in crystal :P
<FromGitter>
<exts> but i want to use crystal in crystal
<FromGitter>
<bew> for what?
<FromGitter>
<exts> you ever use vagrant? you know how the vagrant file is written in complete ruby?
<FromGitter>
<exts> and the backend is also written mostly in ruby
<FromGitter>
<exts> i want to accomplish that and it's nice to write w/ one language

<KCreate> Well you either assume your end-user has crystal installed (probable) and just call it as an external process, or you try to embed the crystal compiler into your program (which is a bad idea imho)
<FromGitter>
<exts> i just want to use crystal as a scripting language inside of crystal, that's about it and the end user wouldn't need crystal installed to execute the binary no?
Guest33797 has quit [Ping timeout: 268 seconds]
<FromGitter>
<bew> crystal is not meant to be a scripting language (no eval, it's compiled..)
<FromGitter>
<KCreate> I don't think that's possible
<FromGitter>
<KCreate> The end user doesn't need to have crystal installed as long as he has all the libraries your program gets linked against.

hey people, how comes and you don't provide arm builds ? it sounds so much difficult to install crystal in a little raspberry pi
<vasilakisfil>
E: The list of sources could not be read.
<vasilakisfil>
this is what I am getting
<FromGitter>
<bcardiff> @exts you can build a crystal program that includes de compiler. But the challenges will be how to share context between them and with which sort of prelude you want to host the scripted program. Yo you have a fixed interface something is doable, at the end of the day the specs, the playground and (i think) icr do something like that. But you will need to compile it and if you depends on external libs it's another
<FromGitter>
... consider.
balduin has joined #crystal-lang

yeah I would like to avoid that
<vasilakisfil>

<FromGitter>
<fridgerator> @vasilakisfil Unfortunately I don't run on arm, I only know of these packages. I believe the error you showed though is usually related to a malformed line in a souces list file

Anyone know how crystal's fibers work with c bindings? I'm adding evented libcurl support (or trying to) but I don't want to get to the bottom of the rabbit hole and find out I actually can't do what I'm trying to do.
<RX14>
depends how libcurl's evented stuff works

it's likely it'll be easier just to write binding for whatever protocol in crystal

in all seriousness I do think we need to bring down the time that merging PRs takes

I think it's a good goal to match them

<sdogruyol> indeed, i agree
<FromGitter>
<sdogruyol> they have great community / dev cycle management

rust has *less* PRs open than crystal but 15x crystal's amount merged

<sdogruyol> they have more dedicated people too
<RX14>
for sure
<FromGitter>
<sdogruyol> i really wish we have more people like you
<RX14>
well I didn't make that many PRs before wednesday
<FromGitter>
<sdogruyol> i mean it's not PRs
<FromGitter>
<sdogruyol> being active and helping people and all others combined, you're doing a great job
<FromGitter>
<redcodefinal> I think we will get there. Crystal is written in crystal so as long as you learn the language you can modify just about anything. I'm happy to contribute code to crystal as long as I'm writing crystal and not llvm or C.
<FromGitter>
<sdogruyol> @redcodefinal yeah, that's also a valid point

i'm curious every time i get an uptick in stars on my Crystal projects - what could've caused that?
<FromGitter>
<mgarciaisaia> @RX14 I swear we will merge the PRs *as fast as Rust* whenever we get half their team size :D
<FromGitter>
<mgarciaisaia> @oprypin the info at Github's Traffic graph doesn't help much, right?
<oprypin>
helps a bit; thanks for reminding about that
<RX14>
I think rust tends to be a lot more liberal with the merge button though, it looks like if 1 person reviews it and it compiles that's good enough
<FromGitter>
<sdogruyol> they got a great CI
<FromGitter>
<redcodefinal> @oprypin That was me, I went through your profile and starred some stuff. ;D
<RX14>
they do...
<RX14>
I keep wanting to rebuild the CI in crystal...
<RX14>
but I have to stop myself every time I think that because it'd never work out
<FromGitter>
<bigDaddyS1oth> Rust is on my list of languages to learn. ATM I'm just trying to stick to Crystal and Go for web stuff.
Guest63789 has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]

<faustinoaq> Just imagine, Rust and Crystal could share code together, rust binding for Crystal, Crystal binding for Rust, it gonna crazy :sweat_smile:
<FromGitter>
<sdogruyol> ぉl
<oprypin>
crazy indeed...
<RX14>
well rust can create C libraries which crystal can bind
<RX14>
there could be work to make that way easier, but I don't quite see the benefit
<RX14>
it would seem to me that rust vs crystal would be on a per-project basis
<FromGitter>
<bigDaddyS1oth> @RX14 trust me though, dude, I'm 22 and self taught as well. I can tell you that you shouldn't sell yourself short; you probably know a lot more than you think. I've spent not even a year learning programming and I can do more than I think I can when I don't think "I'm too young"/fill in the blank.
<FromGitter>
<faustinoaq> <RX14> yeah, and Not only but Nim, D and maybe Go
<FromGitter>
<elorest> I’ve been programming fulltime + for 13 years and have a CS degree, and I learn new things every day from people who have been programming for a year or less.
<FromGitter>
<faustinoaq> For me, this new era of compiled languages is awesome :sparkles:
<FromGitter>
<redcodefinal> @bigDaddyS1oth Well plus @RX14 has a lot of repos that do some pretty cool stuff. Hes gonna have a great resume when he enters the working world.
<RX14>
for sure, the reverse is also obviously true
<FromGitter>
<redcodefinal> @faustinoaq Same here
<FromGitter>
<elorest> for sure. I teach people new things all the time too and learn from people of every skillset.
<RX14>
@bigDaddyS1oth :+1:
<FromGitter>
<bigDaddyS1oth> @faustinoaq are Nim and D even taking off? I've heard nothing about them on any boards or anything.
<RX14>
D's been around ages
<RX14>
and will be around for ages because of that
<RX14>
it's a slow simmer of usefulness
<Papierkorb>
iirc, certain things are built with D, it has a small but loyal user base
<RX14>
Nim... i'm not sure. aparrently there's a nim guy in here
<FromGitter>
<faustinoaq> @bigDaddyS1oth Nim has a new website https://nim-lang.org/ and his twitter is very active
<FromGitter>
<johnjansen> @RX14 is a legend
<FromGitter>
<bigDaddyS1oth> Well everybody is comfy with C++, that's why D has just been sitting around for awhile.
<FromGitter>
<faustinoaq> but I like Crystal more :smile:
<FromGitter>
<faustinoaq> @elorest I'm computer engineer student. and crystal help me to understand many concepts that i didn't know exist.
<RX14>
the reality of CS is quite different to the theory I think
<FromGitter>
<faustinoaq> yeah
<RX14>
i'm pretty glad that I was self taught that way
<FromGitter>
<faustinoaq> me too, self-taught is the way
<Papierkorb>
Many CS guys are flabbergasted when you tell them you don't write statistic or math programs all the time. it'
<Papierkorb>
At least those who I talked to are always weirded out why the world doesn't uses functional programming for everything already
<FromGitter>
<redcodefinal> @papierkorb are you telling me that you can do more than count beans with programming?
<RX14>
not if you use java
<Papierkorb>
redcodefinal, dude my programs can even count apples on top of that
<FromGitter>
<bigDaddyS1oth> I've met too many people getting CS degrees that can't give clear explanations for what object-oriented programming is.
<FromGitter>
<faustinoaq> <Papierkorb> I wish to spend more time in open source projects but University take me a lot of time
<RX14>
really? I'd think that typical degree students here would be too into OO thory by the book and overcomplicate everything lol
<Papierkorb>
faustinoaq, don't worry. Just do what you actually like. If it's writing a helpful tool for you, please do it. If you think it might be useful to others, share on Github. Don't feel pressured
<RX14>
...i shouldn't generalise but that's the stereotype i get
<Papierkorb>
From my university, bachelor graduates or master students I talked to have usually no idea at all on how to take on a project.
<Papierkorb>
They know classes and, if you're really lucky, even heard of unit tests, but they have no idea how to combine it to make something useful other than hacking some homework
<FromGitter>
<redcodefinal> Yeah a cs degree is just a piece of paper that says you sat through some classes and did your homework, it doesn't say what ability you will have as a coder. I'd rather hire a person with 100+ repos on github than a person with a degree and nothing to show for it other than the piece of paper.
<Papierkorb>
hurts to see tbh
<FromGitter>
<bigDaddyS1oth> That's the thing though. Theory is dandy and all but it doesn't amount to much when you can't write any simple programs.
<FromGitter>
<l3kn> @Papierkorb: You are from germany, too? I can totally relate to that
<Papierkorb>
l3kn, in fact I am
<FromGitter>
<bigDaddyS1oth> Or anything practical
<RX14>
in UK universities it seems that most of them recommend taking a year in industry as part of the degree
<RX14>
which I think is quite nice
<FromGitter>
<bigDaddyS1oth> That's why books like *Automate the Boring Stuff With Python* are great because it gets you to thing about what you and other users want. In a simple sense.
<RX14>
london city even lets you do your degree 1 day a week and work the other 4 after year 1 which is super cool
<Papierkorb>
faustinoaq, I'm a CS student too, but I only do it for the bachelor degree. But then, a lot here (and I'm one of them) have been coding for 10+ years. If you started programming at university then no one expects you to have a similar amount of knowledge after ~2 years. Just keep being curious, and don't fear taking on a complex problem.
<FromGitter>
<ltran> degrees are nice. but doing real work is great. balance it out and do what you feel moves you forward.
<FromGitter>
<bigDaddyS1oth> I just have to do a work study, here in America. And God knows if they'll give me any real work
<FromGitter>
<ltran> like. crystal :P
<FromGitter>
<faustinoaq> Well, I think that CS is mainly Math, Calculus and Physics. Programming skills are self taught
<Papierkorb>
imho, too much Math. I'm not saying that CS shouldn't contain any Maths, but in many unis, 3/4 of CS is maths
<FromGitter>
<redcodefinal> Crystal is a great opportunity for programmers trying to make a name for themselves because there is a huge amount of libraries written in other languages we need in crystal and they need to get ported. It'd be great to slap your name on some nice projects
<RX14>
yeah I feel like I should do that lol
<FromGitter>
<redcodefinal> I hate how much math there in in CS. 70% of it isn't even useful, you'll probably never need it. I've never needed calculus a day in my life
<FromGitter>
<ltran> btw, anyone played with protobuf ? ;)
<FromGitter>
<faustinoaq> is in spanish, but the article says that even ary, the creator of crystal did't finish CS :sweat_smile:
<Papierkorb>
The issue is not Maths. The point of it is teach you how to tackle problems, thought patterns et al. But many professors aren't focusing on that, but want to turn you into math people. Which would be fine if you were studying maths.
<RX14>
maths and CS theory is pretty useful though
<FromGitter>
<faustinoaq> yeah, my physic professor says that all time
<FromGitter>
<bigDaddyS1oth> Yea all are doing systems related stuff and I'm just wanting to do web stuff with Crystal. 🤣
<FromGitter>
<redcodefinal> Some maths and cs are pretty useful. I wish they'd start teaching Lambda Calc because thats the math that is most analogous to programming languages.
<FromGitter>
<faustinoaq> I wish to do Windows exe's :smile: someday
