00:02:27shashlickYou'll need to change the GitHub url and folders up a bit
00:06:51FromGitter<gogolxdong> very well , I kind of understand how the .cfg works, thanks. I found there are some difference between the mirror and my repository, will share my repository later.
00:08:36shashlickIt's funny, the GitHub repo is the mirror, and it is different from the official repo on googlesource.com
00:08:58shashlickAnd both are different from the webkit GitHub
00:09:23FromGitter<gogolxdong> it says `Unofficial mirror of the WebKit SVN repository`
00:10:33FromGitter<gogolxdong> google takes webkit and makes its own browser core named blink.
00:11:23FromGitter<gogolxdong> I think WebKit repo is the original.
00:50:22FromGitter<AjBreidenbach> does this look like it's in a state where it's ready to be published? https://github.com/AjBreidenbach/napibindings

01:36:06FromGitter<gogolxdong> @shashlick does the n.prepare section has to be gitremote ? chromioum is a huge project, will nimgen git clone all the codes?
01:39:27FromGitter<gogolxdong> It pulled with --depth=1 and with `error: Sparse checkout leaves no entry on working directory`
01:40:05shashlickThat's cause that repo doesn't have those folders anymore
01:40:21shashlickSee how it is trying a sparse checkout
01:40:31FromGitter<gogolxdong> Can I change n.prepare to local directory?
01:40:54shashlickIf files are already present, you don't need that section at all

01:41:08shashlickI use it to automate wrapping
01:41:58FromGitter<gogolxdong> yes, I put nimkit.cfg under WebKit/Source/core/dom/ where Node.h lies in.
01:45:11FromGitter<AjBreidenbach> are you guys making a browser?
01:45:37FromGitter<gogolxdong> yes, I am trying to make a nim native browser.

04:55:52FromGitter<data-man> @shashlick: Just an idea for nimgen: to use gcc -E -P. It's reduced gcc's output.

10:08:23FromGitter<Varriount> @zacharycarter An initial test against the V4 signing code looks correct.
10:09:39FromGitter<Varriount> The next step will be writing up a tool that validates the procedure against the test cases supplied by AWS.
10:10:11FromGitter<gogolxdong> Are you testing s3 client ,it's correct .
10:10:34FromGitter<Varriount> No, I'm writing my own
10:10:48FromGitter<gogolxdong> ec2 client has some problems.
10:11:11FromGitter<Varriount> Currently my code only generates the signing information.
10:12:10FromGitter<gogolxdong> failed to see any difference between your implementation and AWS documentation, we are stuck at ec2 client.

10:15:21FromGitter<Varriount> This is an implementation that is currently only on my laptop.
10:15:41FromGitter<Varriount> It doesn't make requests.
10:16:14FromGitter<Varriount> It doesn't even do all the data preprocessing required.
10:16:43FromGitter<Varriount> This new code only generates the authorization data
10:17:45FromGitter<Varriount> @zacharycarter @gogolxdong https://gist.github.com/Varriount/b4c817b46ea5c1b141af7791ff2dbcf7
10:18:31FromGitter<gogolxdong> I checked your sigv4 with AWS documentation, as for ec2 client , the payloads need sorting, and either use X-Amz-Credential in payload or use Authorization in header to issue a canonical aws sigv4 request.
10:19:14FromGitter<Varriount> As I have just said, I am not working on that old code. It wasn't even *my* code really.
10:19:32FromGitter<gogolxdong> ok , I see.
10:20:04FromGitter<Varriount> The gist I just posted contains new code.
10:21:07*aguspiza joined #nim
10:24:03FromGitter<exts> does nim have union types?
10:24:11FromGitter<exts> google's sucking right now
10:24:38FromGitter<gogolxdong> you can use object variant.
10:24:40FromGitter<alehander42> it depends on what you mean by "union" types
10:25:04FromGitter<alehander42> it has variants and also "A | B" types
10:25:23FromGitter<exts> alright let me try
10:34:39FromGitter<zetashift> Are "A|B" types simply enums?
10:39:09*xet7 joined #nim
10:39:26*miran joined #nim
10:44:18FromGitter<exts> eh object variant works, but it's not the ideal approach I wanted. i like how unions work in other languages and I tried using `Type|Type` and it didn't work for a table value.

14:06:21FromGitter<Varriount> @gogolxdong You need to pass in an appropriate datetime object. It's currently using the one from the test suite.
14:07:33FromGitter<Varriount> The URI also needs to match, as well as a couple of other parameters.
14:09:59FromGitter<gogolxdong> I used "ec2.us-east-2.amazonaws.com" as URI
14:10:10FromGitter<mratsim> @NoOP, I remember a —app:lib flag
14:10:52FromGitter<mratsim> but iirc there were some extra flags to remove NimMain and maybe initialize the runtime properly
14:12:46FromGitter<gogolxdong> @Varriount What is the uri in createAwsAuthorization? Shouldn't it be "/"?
14:14:09FromGitter<gogolxdong> "ec2.us-east-2.amazonaws.com" as host.

17:02:48dom96oh well, I'll add an issue
17:03:11FromGitter<k0pernicus> Running the `nimble test` task in the root may introduced some flexibility in order to find automatically nim libs, no?

18:17:00dom96Try curl and if it works, see what httpclient does differently
18:17:03dom96Could very well be a bug
18:18:04FromGitter<Varriount> dom96: Ah, nevermind, my fault.
18:18:18FromGitter<Varriount> I was appending the wrong variable to the URL
18:19:00FromGitter<Varriount> dom96: I now have a (fairly) clean and efficient AWS signing procedure. :D

19:43:23FromGitter<k0pernicus> I checked on `strutils` and `sequtils` but I did not found a procedure to tranform a sequence of chars into a string… ⏎ Also, on the internet, people are using a custom function `toString` to do that. ⏎ Is there a procedure, in the std, to do that please?
19:45:51*NoOP quit (Read error: Connection reset by peer)
19:47:20Yardanicok0pernicus: there's probably no that procedure in the stdlib, but it's not hard to make one
19:47:44FromGitter<k0pernicus> I agree: ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5aca71e0109bb043329f426f]
19:47:50YardanicoJust use toString procedure from stackoverflow :)
19:48:07FromGitter<k0pernicus> @Yardanico Already copy/pasted :-p
19:48:26FromGitter<k0pernicus> But it seems there are issues with decimal characters...
19:48:44Yardanicowhat problems?
19:49:12FromGitter<k0pernicus> @[‘\x01’, ‘e’, ‘l’, ‘o’]` gives the `elo` string
19:49:30FromGitter<k0pernicus> (instead of `1elo`)
19:50:59FromGitter<data-man> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5aca72a3080a3850530e4cf4]
19:52:18FromGitter<k0pernicus> @data-man Thanks, but there is the problem with hexadecimal characters
19:52:33FromGitter<k0pernicus> ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5aca73015f188ccc154340fc]
19:52:42FromGitter<k0pernicus> Returns `ab`
19:53:56FromGitter<Yardanico> @data-man why would you use unsafe features for this simple problem ? :)
19:54:09FromGitter<Yardanico> I know it's more performant, but still
19:54:17FromGitter<data-man> @Yardanico: It's faster :)
19:54:24FromGitter<k0pernicus> It’s hacky :-p
19:54:34FromGitter<data-man> @k0pernicus: ```ab``` for me
19:55:16FromGitter<k0pernicus> Yep, but, for me, the good behavior is, for `@['\x01', 'a', 'b’]`, to return `1ab1
19:55:25FromGitter<k0pernicus> And not `ab`
19:57:08dom96k0pernicus: why do you have a seq[char] in the first place?
19:58:50FromGitter<data-man> ``````
19:59:50FromGitter<k0pernicus> @dom96 I am comparing two strings and add informations in a sequence of characters (a number between `0` and `9` or a character between `a` and `z`) - just for fun (dictionary compression challenge)
20:00:26dom96k0pernicus: so use a string, it's mutable :)
20:00:29dom96You can 'add' to a string
20:00:49FromGitter<k0pernicus> So, for example, if you compare `content` and `contents`, it returns `7s` (because the 7 first characters are the same, but `s` is just an added information)
20:00:54FromGitter<k0pernicus> Performance are the same ?
20:01:08dom96yes
20:01:17FromGitter<k0pernicus> Oh ok, cool :-)
20:01:48FromGitter<k0pernicus> Just an habit using Python so...
20:02:21dom96Keep a note of these things and write a "Nim for Python programmers" :)

20:43:14FromGitter<mratsim> works for me™
20:43:29FromGitter<k0pernicus> Also, I don’t understand the behaviour of `result` for the case of `sequence`… ⏎ For example, this code throws an exception (because `result` is a pointer to a non-initialized sequence) ⏎ ⏎ ```code paste, see link``` ⏎ ... [https://gitter.im/nim-lang/Nim?at=5aca7ef15f188ccc15436d13]
20:44:01FromGitter<mratsim> ```proc ex(): seq[int] = ⏎ result = @[] ⏎ for i in 0..10: ⏎ result.add(i)``` [https://gitter.im/nim-lang/Nim?at=5aca7f112dfcfffd2b2c3aef]
20:44:50FromGitter<k0pernicus> Makes sense… As `result` has been initialized and can be modified, it correspond to an implicit `var result: expected_type`
20:44:53FromGitter<k0pernicus> Thanks @mratsim
