ingy I'm setting up travis for a multilang project and using perl6 as an addon, but it doesn't install zef 00:45
I see this works: github.com/perl6-community-modules...travis.yml
but mine fails: github.com/testml-lang/testml/blob...is.yml#L12
timotimo not sure what the perl6 apt package gets you on those ubuntu versions the yhave 00:46
ingy sudo: zef: command not found travis-ci.org/testml-lang/testml/b.../382958845
timotimo potentially a version far too old to run zef
ingy right, so open to suggestions :) 00:47
raschipi You need to manually install it. Those comands in the first one aren't using zef, they are installing it.
timotimo Get:21 us-central1.gce.archive.ubuntu.com/ubuntu trusty/universe amd64 rakudo amd64 2013.12-1 [2,448 kB]
yeah, no.

timotimo ingy: there's an apt repository there
ingy ok
00:50 lain0n joined
ingy timotimo: is that supposed to install perl6 and zef bins? 00:53
zef still not found
timotimo there's more info about that topic in the readme of that repository
there's a command you need to run

timotimo looks like ou forgot the important part 01:13
oh, huh?
01:13 wamba left
ingy what's that? 01:13
timotimo no, that should really have been everything
i misremembered the install-zef-as-user shell script
ingy do I need that? 01:14
timotimo no
of course
sudo won't take the PATH from your environment
so it won't find zef when you sudo it
however, it tells you to "zef install" rather than "sudo zef install" in the rakudo-pkg readme 01:15
it'd surely be good to have an explicit mention of that there
in the readme of rakudo-pkg i mean
until then, just leave out the sudo for zef and perl6 invocations and i think that should make things work
ingy aye
timotimo well, that looks better 01:19
ingy one error at a time! 01:20
timotimo rome wasn't continuously integrated from day one 01:21

ingy timotimo: since the testml-compiler is JS and JS is one of the runtime langs I made this interactive demo site testml-lang.github.io/testml/?type...p;view=tap 01:23

timotimo i don't know coffeescript :) 01:25
other than that it looks neat 01:26
ingy coffeescript is the most straightforward syntax of any lang I have come in contact with
it just js minus a ton of syntax :) 01:27

Reviews relationship between ~~ and ACCEPTS.

Right now there is only a short definition in the first, and a pointer to the last. It's nice to have the docs for ~~, since it's a single point of entry; `ACCEPTS` page is generated from many pages. So I would say it's better to close #1913, since it's not indexed and looks like a sufficiently good reference.

AlexDaniel Summertime: speaking of which, do you expect alerts to posted before the release or after? For example, 2018.05 will come with this change: 09:44

not that

I think, don't make a promise 09:45
AlexDaniel m: say %(<a 1 b 2 c 3>).keys
evalable6 (b a c)
AlexDaniel m: say %(<a 1 b 2 c 3>).keys
evalable6 (c a b)
AlexDaniel ↑ this is now random
the order I mean
09:45 wamba left
AlexDaniel IMO that's alert-worthy, just to make it easier for people 09:45
Summertime there are some things which are going to be obvious to alert about, some things are going to be someone coming in with their project on fire (because why not run latest without testing!) and you'll go "oh that should of been alerted too" 09:46
AlexDaniel if I post the alert now, it's somewhat useless as you'd need to build blead rakudo to test it out…
if I post after the release, then someone can say that we could've alerted earlier, so why didn't we
Summertime but an alert now will also act as an appetizer! 09:47
it seems silly to wait for news to go through all the blogs like hash randomizing has done now, and then have an alert pop up, so I'd say as soon as you think of it would be best 09:48
09:48 broquaint joined, Bucciarati joined
Summertime as long as its searchable by version affected, it shouldn't be a problem, updating a project -> go to alerts -> search for $upgrading-from <= $alert-version <= $upgrading-to, would probably be the most common use 09:51
hmm, the alerts api documentation page seems to be outputting blank though, might be my browser though 09:56
AlexDaniel Summertime: I don't think it's documentation 09:59

mahafyi i simply cannot understand lazy list, lol. Can't get how it works at all..anyways, what i am looking at first is: (see earlier pastebin) if i need to use multiple regexes in the File::Find arg 'name', is it possible at all 13:39
raschipi mahafyi: Can't it be a regex with an alternation? 13:41
mahafyi i guess in this specific case, i can think like this: can we ouse an OR condition in regex (probably, it is not the correct way to epxress the question)
raschipi, thanks, i guess i have the term to google for now, lol
raschipi alternation means OR
Just another way to say what you said right after me. 13:42
Can't you use multiple File::Find instances?
13:42 itaipu_ left 13:43 itaipu joined
mahafyi yes, thats what i have in a pseudocode now, run it twice one after another 13:43
raschipi Then put the two lists togheter. 13:44
mahafyi it may not be needed, i just need to concatenate all the files in each list into two separate files, one for each list
each file will have headers, what is the equivalent of sed, in order to do -> (I need to delete the header lines - along with the carriage return) 13:46
raschipi You could also try to give it a junction, something like (/regex1/, /regex2/).any
or /regex1/|/regex2/ 13:47
mahafyi in which case, i will need to recurse the list elements with a IF condition i guess 13:48
there is such a tremendous knowledge base inside any one thing! its very dense, if that is the correct word. I guess one can eventually reach a point when the thing needed will come like a reflex. but now its reading 90% working 10% lol. 13:54
timotimo i'd rather read a thousand lines of documentation and write one line of code than reading just one line of documentation and have to write a thousand lines of code for the same result :D
mahafyi sure, i cannot remember which , i will find it, i wrote some several dozen lines for a rosetta code problem, and find a one liner in answer, 13:57
timotimo yeah, especially when it comes to not having to write out loops, perl6 is very strong
not as strong as languages like APL or J, though

mahafyi what do i do for: find and delete all lines that matches a regex, but ignore the first. do i need to recurse the whole file or is there a better way to do ? the file may be over a million lines. 14:47

mahafyi i havent yet written ? i am planning what to write before i write. Lets say two csv files with headers are concatanated, i need to delete the header lines after. 14:49
raschipi m: for ^10 {once next; .say}
camelia 1
mahafyi so , i can go thru in a looop, line by line, or i can do something like, what i'd do with sed from command line.
raschipi either are possible 14:50
timotimo don't forget you'll likely have to output the first line back so it doesn't disappear
mahafyi timotimo, right, delete all the headers, except the first..
raschipi m: (^10).tail(*-1).say 14:51
camelia (1 2 3 4 5 6 7 8 9)
raschipi tail(*-1) skips the first item in a list.
mahafyi which means each line in the file has to be in a list? 14:52
timotimo m: <foo bor baz quux boot shoot bleep>.grep({ not $++ or /o/ }).say
camelia (foo bor boot shoot)
timotimo m: <foo bor baz quux boot shoot bleep>.grep({ not $++ or /<-[o]>/ }).say
camelia (foo bor baz quux boot shoot bleep)
timotimo hold on ..
m: <foo bor baz quux boot shoot bleep>.grep({ not $++ or m/<-[o]>/ }).say
camelia (foo bor baz quux boot shoot bleep)
timotimo m: <foo bor baz quux boot shoot bleep>.grep({ (not $++) || m/<-[o]>/ }).say
camelia (foo bor baz quux boot shoot bleep)
timotimo ah, of course
m: <foo bor baz quux boot shoot bleep>.grep({ (not $++) || !m/o/ }).say 14:53
camelia (foo baz quux bleep)
timotimo ^- remove all entries that have an o in them, except the very first
demorgan's law lets you make it less strange 14:54
mahafyi timotimo : ok great.
timotimo m: <foo bor baz quux boot shoot bleep>.grep({ not ($++ && m/o/) }).say
camelia (foo baz quux bleep)
timotimo but you'll probably want map, not grep
i.e. do changes to lines, not just throw lines out
m: <foo bor baz quux boot shoot bleep>.map({ $++ ?? S/o/AAAAA/ !! $_ }).say 14:55
camelia (foo bAAAAAr baz quux bAAAAAot shAAAAAot bleep)
timotimo replace the first o with AAAAA except if it's the very first line
well, entry, not line. you'll have to do line-splitting yourself
raschipi .lines isn't enough? 14:56
timotimo it is enough
i just meant my code doesn't do anything regarding lines 14:57
it relies on the list that comes in to already be whatever you need
raschipi right
mahafyi wow, ok let me go thru this
timotimo $++ is just a cute little trick for "false one time, then true every other itme"
or you can split the list up front into "first element" and "all other elements" and only .map on the "all other elements" list 14:59
but that's probably also awkward

mahafyi I suppose we can use sed from inside a program? 15:00

tbrowder_ question: why are backticks used in markdown and other text files? are they re 15:04
lucasb it's code markup 15:05
tbrowder_ are they treated differently than single right quotes? 15:06
timotimo yes, they are
tbrowder_ what is their effect in, say, markdown?
i understand the effect in shell... 15:07
timotimo markdown turns `foo` into <code>foo</code> or something like that 15:08
tbrowder_ treatment in pod 6, perl 6?
raschipi in markdow it renders the text in monospace font and also keeps spaces intact (markdown usually supresses multiple spcaes)
tbrowder_ ah, right, i forgot, thinking of three backticks for a code block

lucasb to show that even with a .item it gets iterated over, while (1,2,3).item and [1,2,3].item doesn't
raschipi m: .say for $(1,2,3) 15:26

Zoffix lucasb: that's 'cause () and [] are already Iterable, but \() ain't, so it gets made into an Iterable by calling .list, which returns positionals from the capture in non-conted List 15:55

lucasb ok. but .item alone wasn't supposed to make it itemized?
Zoffix lucasb: it did. But a Capture, even an itemized one, isn't an Iterable 15:58

SourceBaby timotimo, Sauce is at github.com/rakudo/rakudo/blob/154d...le.pm6#L16
timotimo so the default implementation literally just creates a Scalar and puts the object on it, and returns the scalar
raschipi So it's the Iterable role that interacts with the $() and for receives something different then?
Zoffix I think it's the Iterable role that makes `for` decide how to loop over it 16:02

lucasb github.com/rakudo/rakudo/commit/71...64399c883c
(well, for the Capture thing) 16:03
Zoffix lucasb: you're calling "item" BEFORE giving `for` a non-Iterable thing.
lucasb not the general class C { method list {...} } case 16:04
Zoffix It doesn't have any effect on what happens after `for` converts your thing to an Iterable thing
16:05 troys joined
lucasb ok, I'll get it after a while :) 16:05
I just think is strange that 'for' tries to make a non-Iterable thing into a Iterable a thing, while (1,2,3).item and [1,2,3].item are really iterable things and 'for' treats as itemized 16:06
Zoffix You put bunch of oranges into a box. Then you put them into a bag and hand it to me, saying "here, eat this". It doesn't look like food, so I have to open up both the bag and the box to get to the oranges and by that time they're not in any boxes, so I eat them one by one. 16:07

Moving @fluca1978's explanation to a method subsection

So that it can be indexed properly. Also added other two multis that use ~ in a rather more natural way. Closes #2053.

Zoffixlucasb: actually my explanation was likely inaccurate
Zoffix │ Looking at p6for desugar, it don't care about Iterable at all: github.com/rakudo/rakudo/blob/mast...#L561-L578
Zoffix │ But, Iterable provides the `.item` method that shoves things into container:
