anyone know when that began and if so what caused it?
03:07 khw joined
cale2 I know I talk about elixir alllll the time, but 03:08
it has a neat feature where you can pattern match on binary data
Can you use perl6 grammars to pattern match on binary data?
Is that how you might interface with new data formats, for example?
samcv the builds are passing on TravisCI 03:09
binary data as in, non-text?
you cannot use grammars for non-text
cale2 samcv: Yeah, like destructuring a TCP header or something 03:11

RabidGravy gfldex, I actually have one somewhere that I use for my own purposes, maybe I'll stick it in at some point 14:11
gfldex RabidGravy: I was thinking about useing META6 to create a skeleton for a module, run git init and talk both to github and travis. 14:13
much easier to teach beginners how to do it properly that way
RabidGravy I'd say Talking to github and travis" would be out of scope as a script to distribute with META6 but as an example or something separate yes 14:14
generating a properly formed META file with no other dependencies would be an idea though 14:15
gfldex true, in that case a separate repo with a meta6 executable makes sense

cale2 is there an oauth1 example in perl6 somewhere? 17:33

brokenchicken No idea what version it is github.com/zoffixznet/perl6-Twitte.../OAuth.pm6
cale2 i'm reading it now 17:36
RabidGravy cale2 there's also arudimentary OAuth implementation in github.com/jonathanstowe/WebService-Soundcloud 17:51
I keep meaning to split it out 17:52
cale2 The part that confuses me about the protocol is how to sign requests. A lot of oauth1 libraries will generate an oauth signature, but then you have to attach that signature to a request 17:59
do you append the oauth signature to the request header? do you send in the oauth sig and the header as two separate strings?
what if you also have post data? do you concat the request header, oauth sig, AND payload data?
brokenchicken sounds like the sign() method from Twitter::OAuth answers all those ques5tions 18:03
cale2: perhaps this gives an idea? github.com/zoffixznet/perl6-Twitte...UA.pm6#L19 18:05
That's all one Authorization header that gets sent: github.com/zoffixznet/perl6-Twitte...UA.pm6#L27 18:06
cale2 brokenchicken: $ua.post(url, headers, content) <- That makes sense. But different oauth libraries (and different HTTP libraries) play together differently 18:08

samcv i don't mean in perl 6, but in C
so I guess it fits in a 64-bit, unsigned. I think i see what I was doing wrong with my type generation 19:36
brokenchicken ? 19:37
gfldex cale2: in Perl 6 the return type of a function is unknown at compile time. The return type is a misnomer. It's a return type constraint. 19:40
cale2 This is a good post if you're wondering what I meant about point free: buffered.io/posts/point-free-style-...-good-for/ 19:44

lizmat gfldex: known at compile time ^^^ :-) 19:46
cale2 Honestly it's not much different from a feed operator and the like. I was just thinking I could do an infix operator that was similar
gfldex lizmat: that's a return value, not a return type
gfldex puts down the hairsplittingknife
lizmat :-) fwiw, I think it is *also* a return type, namely Int 19:47

cale2 Does perl6 have generic types in the sense that it can match two generic types?
19:51 bjz_ joined
gfldex not really but you can use a subset to match against a Junction of two types 19:51
cale2 Prob not, because you'd just have something like `(Any, Any) returns Any`
gfldex please don't ask what a Junction is
cale2 A junction is a glorified enum 19:52
gfldex no
19:52 agentzh left
cale2 But in any case, if you don't know the types beforehand, you can't do it 19:52

RabidGravy I like the compose operator but can't type it ;-)
cale2 I'm guessing it doesn't rely on types, it just assumes that you know what you're doing
Yeah, it relies on arity 19:58
gfldex: junctions aren't that hard to understand. How is it not like an enum?
brokenchicken doesn't see the relation between Junctions and enums 19:59

cale2 How is that junction example any different than mapping foo over a list of 2,3,4,5,6,7,8,9 ?
20:08 agentzh left
cale2 So a junction is a special list of objects that allow threading without using a special thread operator :) 20:08
b2gills Calling it threading leads many to make that mistake 20:09
cale2 This makes sense. So when you say 2 ~~ 3|4|2|5, it is matching 2 against all the objects at the same time
20:09 agentzh joined
b2gills effectively at the same time 20:09
RabidGravy it's either all of the values at once, any of the value or none of the values 20:10

cale2: the interesting bit about Junctions is how the objects are superimposed, not that there's a list of objects. Which is why I see little relation to enums

RabidGravy maybe pull them to community trust or ditch them 21:08

japhb Is there a portable way to tell Perl 6 to unbuffer $*IN? (I know about using e.g. Term::termios, I'm asking if there's something that will work on Windows too.) 23:42
geekosaur that question is moderately confused, as there's at least two lyers of buffering, one of which does not apply to Windows 23:43
...and you mentioned that ibe 23:44
*one
23:45 zacts left
geekosaur (windows is always in character at a time mode, at the driver level. this is distinct from the input buffering most likely provided, in the case of moarvm, by libuv --- which is also likely to default to line mode.) 23:45
japhb geekosaur: I am aware of Moar buffering to look for combining characters, and the terminal line buffering ... what others do I need to worry about if I just want 'getc' to respond immediately after a keypress?
Ah, I didn't realize a terminal app in Windows would be getting characters. Hmmm, I didn't assume libuv was doing additional buffering of its own in the middle. :-/ 23:46
*getting characters immediately 23:47
23:49 pmurias left
japhb OTOH, libuv either must do no buffering, or pays attention to the termios settings itself, or Term::termios couldn't successfully set raw input mode. 23:49
That was tortured English, sigh 23:50
geekosaur it's typical for programs to check isatty() (which uses termios) and set line vs. block buffering 23:51
I'm looking at the libuv docs and they say very little about buffering. I suspect libuv doesn't expect to be used with terminals 23:52
it's all about the sockets >.>
japhb Sigh. 23:53
But in any case, I expected the line v. block buffering. My point was that when Term::termios does .makeraw and goes to non-buffered format, libuv would have to notice that and turn off internal buffering (if it has any), or that operation wouldn't actually do anything useful. 23:54
geekosaur actually it's worse than that 23:55
japhb On the downside, I just tested it ... the MoarVM buffering looking for combining characters is problematic, because it's effectively 'unbuffered, but with a one character delay'
geekosaur if moar is using normal handles for this, libuv is not expecting it; it does not check for tty, it expects you to be using uv_tty_t in that case
geekosaur is reading code presented in github.com/libuv/libuv/issues/852 23:56
japhb looks
geekosaur and yes, if you want raw input you need to disable encoding handling. I didn;t notice a way to do that on the fly with p6 published api
basically its the node devs asking the same question you were :) 23:57
er, node.js
japhb heh
23:58 agentzh joined, cyphase left, lukiramu left, _28_ria left
japhb .ask jnthn is there a way to stop doing encoding handling on $*IN? I want to get truly raw .getc (one character at a time, as soon as the keypress happens), without the delay loop that comes from looking for combining characters .... 23:59
yoleaux japhb: I'll pass your message to jnthn.
