Finally I got it. I was using ctx.reques.body instead of ctx.params.body with kemal

How do I use libui.cr?

I want to run the samples, but I have no idea how :(

Is crystal regexp fast?

From IRC (bridge bot)

@FromIRC

<bmcginty> @krypton97: fast enough for the bits I've used it for.

<bmcginty> @krypton97: if you want to check for yourself, try using the benchmark module.

<RX14> @krypton97 it uses libpcre which is very optimised

I'm looking to do some validation

@hanyuone

Argh C is confusing :(

From IRC (bridge bot)

@FromIRC

<Yxhuvud> rx14: But libPCRE is not statically linked, is it? Because if not, then the minimal cost is the cost for walking the linking, which is not necessarily insignificant.

<RX14> wat?

<RX14> it's linked once when you start the program

<RX14> then it makes no difference

<RX14> disregarding LTO

Hanyuan Li

@hanyuone

Argh how do you build GTK+ w/ Homebrew

From IRC (bridge bot)

@FromIRC

<Yxhuvud> sure but calling functions in it DO make a difference as it is always a jump or two away.

<RX14> no

<RX14> it's just a normal function call

<bmcginty> I'm blanking out on something here. I've got a pointer of data being returned from a library (libpq). Somehow, when the gc is running, it's segfaulting. I have a suspition it's trying to collect something from libpq land that libpq has already handled. Anyone seen anything like this before or have suggestions on where to go from here?

From IRC (bridge bot)

@FromIRC

<bmcginty> fault is in gc_clear_stack_inner, for what that's worth. I've also taken the pointer, created a second pointer, and copied everything over with Pointer.malloc(original_pointer_size) { |i| original_pointer[i] }. so the original pointer shouldn't be used outside of that one area in the program...

@hanyuone

Does anyone know where to start with making a C binding for GTK+?

It honestly seems like a monumental task

Because I have basically 0 knowledge of C

From IRC (bridge bot)

@FromIRC

<Papierkorb> Beginning with Gtk in that case doesn't sound like a good idea tbh

<Papierkorb> The issue isn't even writing the pure binding itself. The issue is first getting structures right, and then the correct integration

<Papierkorb> In terms of Gtk, you also have to deal with GObject, and suddenly you have inheritance in C you have to wrap too.

From IRC (bridge bot)

@FromIRC

<RX14> i havent used gobject but it sounds like a terrible idea

hey @bew, how are you?

@ghost~55586c4815522ed4b3e08557

good! it seems to be a long time, did you take some vacation?

Serdar Dogruyol - Sedo セド

@sdogruyol

yeah, I've just returned from a vacation

Ghost

@ghost~55586c4815522ed4b3e08557

good! So you're ready to return in your crystal ambassador role? ;)

Serdar Dogruyol - Sedo セド

@sdogruyol

I'll do my best :+1:

From IRC (bridge bot)

@FromIRC

<bmcginty> I goofed. not a gc issue (again, when will I learn). I was recursively calling a function.

<RX14> bmcginty, easy way to tell is stackoverflow has "(n times)" in one of the backtraces

@unreadable

I find crystal so much more productive than go. Kinda reminds me about node.js but simpler hehe

And no async stuffs hehe

@LuckyChicken91_twitter

yes crystal is really awesome

Serdar Dogruyol - Sedo セド

@sdogruyol

@krypton97 indeed :100:

unreadable

@unreadable

wondering id there's something similar with try/catch block in crystal o.O

Ghost

@ghost~55586c4815522ed4b3e08557

yep: begin/rescure/ensure (doc: https://crystal-lang.org/docs/syntax_and_semantics/exception_handling.html)

unreadable

@unreadable

Yeah, I've found that

gonna play with it

unreadable

@unreadable

begin/rescue/else works like a charm

Well done crystal team. No more err != nil bs..

Serdar Dogruyol - Sedo セド

@sdogruyol

Oh, what do you mean?

unreadable

@unreadable

err != nil is specific to Golang. Go libraries are written that way so they always return an error (nil or something else)

Serdar Dogruyol - Sedo セド

@sdogruyol

Ahh, now i get it
