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: https://github.com/perl6-community-modules/p6-test-builder/blob/master/.travis.yml	00:45
	but mine fails: https://github.com/testml-lang/testml/blob/travis/.travis.yml#L12	00:45
timotimo	not sure what the perl6 apt package gets you on those ubuntu versions the yhave	00:46
ingy	sudo: zef: command not found https://travis-ci.org/testml-lang/testml/builds/382958845	00:46
timotimo	potentially a version far too old to run zef	00:46
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.	00:47
timotimo	Get:21 http://us-central1.gce.archive.ubuntu.com/ubuntu trusty/universe amd64 rakudo amd64 2013.12-1 [2,448 kB]	00:47
	yeah, no.	00:47
	huggable: deb	00:47
huggable	timotimo, Alpine, CentOS, Debian, Fedora, OpenSUSE and Ubuntu Rakudo packages: https://github.com/nxadm/rakudo-pkg#rakudo-pkg	00:47
timotimo	ingy: there's an apt repository there	00:47
ingy	ok	00:47
	→ lain0n joined	00:50
ingy	timotimo: is that supposed to install perl6 and zef bins?	00:53
	zef still not found	00:53
timotimo	there's more info about that topic in the readme of that repository	00:53
	there's a command you need to run	00:53

timotimo	looks like ou forgot the important part	01:13
	oh, huh?	01:13
	← wamba left	01:13
ingy	what's that?	01:13
timotimo	no, that should really have been everything	01:13
	i misremembered the install-zef-as-user shell script	01:13
ingy	do I need that?	01:14
timotimo	no	01:14
	ah	01:14
	of course	01:14
	sudo won't take the PATH from your environment	01:14
	so it won't find zef when you sudo it	01:14
	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	01:15
	in the readme of rakudo-pkg i mean	01:15
	until then, just leave out the sudo for zef and perl6 invocations and i think that should make things work	01:15
ingy	aye	01:15
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	that's how we'll fix the world!	01:21

ingy	timotimo: since the testml-compiler is JS and JS is one of the runtime langs I made this interactive demo site https://testml-lang.github.io/testml/?type=example&name=math&view=tap	01:23
	it has all the testml and testml-compiler and yaml-test-suite tests built-in	01:23
	and totally interactive	01:24
	and the location url permalinks any state you choose	01:25
	→ mcmillhj joined	01:25
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	01:26
	it just js minus a ton of syntax :)	01:27
	https://testml-lang.github.io/testml/?type=example&name=import&view=mocha is pretty cool	01:27
	→ MasterDuke joined	01:27
ingy	I had to make the compiler API take an Import callback to do imports in the brower	01:29
	p6 tests all work except haven't seen this before: https://travis-ci.org/testml-lang/testml/builds/382969421#L787	01:30

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…	09:46
	if I post after the release, then someone can say that we could've alerted earlier, so why didn't we	09:46
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

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

mahafyi	Hello. I am trying to do this -> https://pastebin.com/VN2wviF8 with File::Find. Can someone tell what eagerly vs lazily create list means please?	13:24
moritz	mahafyi: a lazy list is one that is created as you consume it	13:24
	← Actualeyes left	13:24
moritz	mahafyi: and an eager list is one that is created fully even before you start to use it	13:25

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)	13:41
	raschipi, thanks, i guess i have the term to google for now, lol	13:41
raschipi	alternation means OR	13:41
	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	13:42
	→ itaipu joined	13:43
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	13:44
	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	13:46
	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	13:54
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	13:57
	not as strong as languages like APL or J, though	13:57

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
raschipi	Are you doing it with a loop?	14:48

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	either are possible	14:50

	well, entry, not line. you'll have to do line-splitting yourself	14:55

	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	14:57
raschipi	right	14:57
mahafyi	wow, ok let me go thru this	14:57
timotimo	$++ is just a cute little trick for "false one time, then true every other itme"	14:57

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

enheh_	Hello, I'm having difficulty installing rakudo-star-2018.04. It hangs after printing the line:	18:04
	===> Testing: LWP::Simple:ver<0.101>:auth<Cosimo Streppone>	18:04
	A little investigation found that it's hanging in t/get-unsized.t. It seems it never gets past the line:	18:06

	enheh_: or some firewall getting in the way?	18:08
enheh_	I don't know. How can I find out?	18:08
	As for the firewall, no.	18:08
jmerelo	enheh_: I would use lsof in Linux, but I don't know about Mac. Check first what is the value of the :0localport it's using.	18:09
	→ Zoffix joined	18:09
timotimo	if the port were already in use it'd throw an exception i believe	18:10
	but :0localport just uses any free port, right?	18:10
jmerelo	timotimo: probably... Then, firewall?	18:10
Zoffix	enheh_: I saw someone else say tests were hanging on MacOS in that module, with suspect new tests being to blame. I suggest you report the problem https://github.com/perl6/perl6-lwp-simple/issues and then just skip the tests during installation: zef --/test install LWP::Simple	18:10
enheh_	Yes, this get-unsized.t has entirely new contents since 2018.01	18:11

	jmerelo waits anxiously for mst to reveal the problem.	18:12

	jmerelo: you missed the joke :)	18:13
	ingy: and what that does is wrap Failure.DESTROY method into an empty callable, so anytime it gets called it'd be a NOOP. The default one just emits that warning tho, so you're not missing any critical functionality by doing so.	18:14

ingy	Zoffix: well actually, just using `$!bridge = (require ::(%*ENV<TESTML_BRIDGE>)).new;` fixes the 1515 problem too. so no the workaround isn't needed.	18:32
Zoffix	ingy: and the other one, yeah, I think it's a bug. My understanding is the `package` version installed by `require` is supposed to be replaced by the class	18:33

Zoffix	enheh_: I just filed one. You could add any additional info to it, if you have it: https://github.com/perl6/perl6-lwp-simple/issues/28	18:43
	Like operating system details, etc. I know the release manager of Rakudo Star tested it on MacOS and did not have any hangs, so it's not all MacOSes where the issue exists.	18:44
enheh_	Okay. Zoffix++	18:44

yoleaux	16:28Z <Zoffix> lizmat: I recall like half a year ago you asking why QuantHash objects aren't Iterable. Did you ever figure it out? I notice lack of Iterable makes them get .item from Mu, which is a no-op, and thus you can't iterate over, say, a set as a single item: `dd $_ for $(set <a b c>); # OUTPUT: «:b␤:a␤:c␤»`	20:54
