<raz> yeh, just wrote my own logger middleware. still quicker than remembering all::the::AVDs :⁠P

George Dietrich

@Blacksmoke16

request logging is enabled by default, so wouldnt have had to do anything ;)

@FromIRC

<raz> yeh, next time i need aircraft carrier framework i'll use athena again :⁠D

George Dietrich

@Blacksmoke16

heh

George Dietrich

@Blacksmoke16

ofc PHP has this method built in https://www.php.net/manual/en/function.getimagesize.php

George Dietrich

@Blacksmoke16

should Char define a to_u8! method that delegates to #ord so that you can do like Bytes['G', 'I', 'F']?

George Dietrich

@Blacksmoke16

well ord.to_u8

guess it wouldnt work for all chars so prob not worth it

<alekhine> I'm a sort-of beginner. If I want to learn crystal, should I just go and learn Ruby first?

<alekhine> Hello everyone, btw

George Dietrich

@Blacksmoke16

i wouldn't then you'd have to unlearn a bunch of stuff :wink:

From IRC (bridge bot)

@FromIRC

<alekhine> Gotcha. Are there any decent resources yet?

George Dietrich

@Blacksmoke16

https://crystal-lang.org/reference/ is a good one

From IRC (bridge bot)

@FromIRC

<alekhine> Thanks

<alekhine> I can execute shell commands withing the language?!

<alekhine> ?!?!?!

George Dietrich

@Blacksmoke16

pretty sure you can do that in pretty much any lang but yea

From IRC (bridge bot)

@FromIRC

<alekhine> Wait, really?

George Dietrich

@Blacksmoke16

ruby, php, go, etc at least

From IRC (bridge bot)

@FromIRC

<alekhine> How about C?

George Dietrich

@Blacksmoke16

https://www.tutorialspoint.com/c_standard_library/c_function_system.htm

yup

From IRC (bridge bot)

@FromIRC

<alekhine> Wow, that is... some new information

George Dietrich

@Blacksmoke16

has its uses, but if thats all you need just write up a bash script

From IRC (bridge bot)

@FromIRC

<alekhine> Nah, I want a compiled language

<alekhine> So, here's my real question

<alekhine> Is crystal fun to write?

George Dietrich

@Blacksmoke16

i think so yes, but i dont think it'll help you much if all you want to do is execute a bunch of shell commands

From IRC (bridge bot)

@FromIRC

<alekhine> I've been learning for about a year and a half, but I have not yet found a language I really enjoy using

<alekhine> Lol, don't worry about that. That was just something I wasn't aware of, I won't be wrapping all my scripts in c now

George Dietrich

@Blacksmoke16

that's what bash is for :)

From IRC (bridge bot)

@FromIRC

<alekhine> lol you're right. or python i guess

George Dietrich

@Blacksmoke16

python wouldn't help much either if all you want to do is like

cd /some/dir
cp /some/thing.txt ./
some command --foo

From IRC (bridge bot)

@FromIRC

<alekhine> Bash is still very good at file manipulation. Though I use fish :⁠)

George Dietrich

@Blacksmoke16

by bash i more so kinda meant .sh file

or whatever shell you use yea

From IRC (bridge bot)

@FromIRC

<alekhine> Yeah, Shell languages

<alekhine> Well that answers my questions, I'll go install crystal

George Dietrich

@Blacksmoke16

:thumbsup:

From IRC (bridge bot)

@FromIRC

<ua_> I kinda wonder why he's set on compiled language

From IRC (bridge bot)

@FromIRC

<kevinsjoberg> Is this a bug or not? https://play.crystal-lang.org/#/r/bjk8 I know @Blacksmoke16 was playing around with this a bit yesterday, but I don't know for a fact if its a bug or a limitation. Would like to try fix it if its a bug.

<kevinsjoberg> Perhaps I should fail it as a bug in upstream and see what the outcome is?

@wyhaines

Your add_b does work. What fails is actually the puts.

Add a macro line to show you B after you assign to it:

    {%
      B[key] = { type: @type.name, value: value }
      pp B
    %}

You will see that data is being added.

What is failing is the non-macro access to either A::B or C::B.

From IRC (bridge bot)

@FromIRC

<kevinsjoberg> @wyhaines, sorry I should have been clear. Yes, the macro works. I know the puts is the culprit, but I'd still expect it to work.

From IRC (bridge bot)

@FromIRC

<kevinsjoberg> Why is it breaking upon trying to access the constant at runtime?
