04:33 <FromGitter> <nickbclifford> Hmm, having some weird issues with C libraries again (I just can't escape -.-), getting segfaults when trying to dereference an array pointer in Crystal/turn it into a `Slice`, but no such issues when doing the same directly in C

04:51 <FromGitter> <nickbclifford> Okay I think I see the issue, it's to do with struct flexible array members, seems like something worth opening a compiler issue about

04:56 <FromGitter> <Blacksmoke16> can you share the error/code?

04:59 <FromGitter> <nickbclifford> Well, essentially, there seems to be no way to bind to a struct similar to ⏎ ⏎ ```struct list { ⏎ unsigned length;``` [https://gitter.im/crystal-lang/crystal?at=606947be3153ce63a3ba4f53]

05:01 <FromGitter> <nickbclifford> Treating it as a `Pointer(LibC::Int)` in a `lib` declaration causes segfaults, and I can't see a way to get `StaticArray` to play nice with it either

05:03 <FromGitter> <Blacksmoke16> hm

05:10 <FromGitter> <Blacksmoke16> could try and autogen the bindings with https://github.com/crystal-lang/crystal_lib

05:30 <FromGitter> <Blacksmoke16> did you try like `data : Array(LibC::Int)`?

05:33 <FromGitter> <Blacksmoke16> granted my C knowledge is limited but :shrug:

05:37 <FromGitter> <Blacksmoke16> nvm

11:30 <FromGitter> <oprypin:matrix.org> i don't understand, how do I percent-encode stuff??

11:31 <FromGitter> <oprypin:matrix.org> Python: `urllib.parse.quote("#") == "%23"`

11:32 <FromGitter> <oprypin:matrix.org> Crystal: `URI.encode("# a") == "#%20a"`

11:32 <FromGitter> <oprypin:matrix.org> Crystal: `URI.encode_www_form("# a") == "%23+a"`

11:33 <FromGitter> <oprypin:matrix.org> `String.build { |io| URI.encode("# a", io, &->URI.unreserved?(UInt8)) } == "%23%20a"`

11:34 <FromGitter> <oprypin:matrix.org> is that really what i'm supposed to write every time?

11:34 <FromGitter> <oprypin:matrix.org> what is the default `URI.encode` even supposed to do if it doesnt do anything with `#`

11:35 <FromGitter> <Daniel-Worrall> `URI.encode_www_form("# a", space_to_plus: false)`

11:36 <FromGitter> <Daniel-Worrall> default encodes space to `+`

11:36 <FromGitter> <Daniel-Worrall> > By default, the space character (0x20) is encoded as + and + is encoded as %2B. If space_to_plus is false, space character is encoded as %20 and '+' is encoded literally.

11:37 <FromGitter> <oprypin:matrix.org> wtf this was the correct implementation, did it get deleted? https://github.com/crystal-lang/crystal/blob/18e76172444c7bd07f58bf360bc21981b667668d/src/uri.cr#L256

11:39 <FromGitter> <oprypin:matrix.org> @Daniel-Worrall: note that I'm not encoding a http form

11:39 <FromGitter> <Daniel-Worrall> `URI.encode` doesn't escape reserved characters

11:40 <FromGitter> <oprypin:matrix.org> @Daniel-Worrall: i can see that, yes

11:41 <FromGitter> <Daniel-Worrall> So, is there still confusion on how to percent-code?

11:41 <FromGitter> <oprypin:matrix.org> yes in crystals stdlib

11:41 <FromGitter> <oprypin:matrix.org> i am making a URL that's referring to an item named "foo#20"

11:42 <FromGitter> <Daniel-Worrall> `URI.encode_www_form("foo#20", space_to_plus: false)` is the correct way

11:42 <FromGitter> <oprypin:matrix.org> question: how do I make a URL `/items/#{name}` that can be opened

11:42 <FromGitter> <oprypin:matrix.org> @Daniel-Worrall: again, I'm not encoding a www form

11:42 <FromGitter> <Daniel-Worrall> but since you don't have spaces, you can leave out space_to_plus

11:43 <FromGitter> <Daniel-Worrall> I get that, but that's how it's named in the stdlib

11:44 <FromGitter> <oprypin:matrix.org> no, it's just a method for a different purpose

11:44 <FromGitter> <oprypin:matrix.org> that somehow happens to match what people want in non-form-encoding context

15:22 <FromGitter> <ryanstout> One quick thing that I'm worried might affect people besides myself. (And sorry to be "that guy") When I went to https://crystal-lang.org/ and hit learn, I didn't see the "Next" links or any navigation elements to tell me that I'm in a full guide/tutorial, since the "Next" stuff only shows up once you get to the bottom of the page. I must have looked at that page 5 times thinking "where is the tutorial stuff"

15:22 <FromGitter> ... (Which I remember from that past)

15:23 <FromGitter> <ryanstout> Having the full tutorial tree on the left would be one solution (so you could jump past the install stuff if you already have it installed for example)

16:42 <FromGitter> <oprypin:matrix.org> @ryanstout: i dunno, like, the navigation split was an explicit decision to change. didn't you see the navigation tabs at the top? ⏎ the obvious small takeaway i have is this though: https://github.com/crystal-lang/crystal-website/pull/129

17:39 <FromGitter> <asterite> It's strange that Learn doesn't take you to the reference. I agree it's pretty confusing

20:46 <FromGitter> <oprypin:matrix.org> i recapped my thoughts on `URI.escape` and commented here: https://github.com/crystal-lang/crystal/pull/7997#issuecomment-813096783 cc @Daniel-Worrall

21:48 <FromGitter> <ryanstout> @oprypin:matrix.org the top nav disappears once you scroll, at least on my screen size. Totally understand there is some variance in opinion here, but I think the value in having a full hierarchy of "learn X language" sections visible is so you can quickly figure out what parts you need to read to learn something. Seems to be a common paradigm also: https://doc.rust-lang.org/book/

21:48 <FromGitter> ... https://docs.python.org/3/tutorial/index.html https://nim-lang.org/docs/tut1.html Anyway, just wanted to convey my experience. Thanks everyone for the hard work on Crystal!

22:15 <FromGitter> <Blacksmoke16> you can make it so the tabs are sticky, might be worth it?
