rjbs How can I (probably with throws-like?) test that the exception message from some code matches a regex? 00:29
I tried: throws-like(sub { ... }, /foo/) but that's no good. 00:30
timotimo why would you ever want to match the message with a regex?
japhb timotimo: Testing that the exception class message method is correct? 00:31
rjbs What japhb said.
Let me state my real goal, and you can tell me what you think. 00:32
I have a class, and it has a bunch of error conditions that die("foo")
Creating a hierarchy of exception classes seems like overkill. 00:33
timotimo hm
fair enough
rjbs I want to see "did I get the right error in this case"?
Normally, I do something like: my $error = exception { some_code }; like($@, qr/too many chefs/);
er, s/$@/$error/
timotimo hmm 00:34
rjbs Hm. The web page says: 00:37
throws-like($code, $ex_type, $description?)
but the source of Test.pm says:
sub throws-like($code, $ex_type, $reason?, *%matcher) is export {
00:37 eli-se left
rjbs that %matcher thing seems plausibly important? 00:37
TimToady put message => on teh // 00:39
rjbs Okay. Do I want X::AdHoc for $ex_Type or anything? Or just *? I'll go try!

vendethiel why is unit need there? github.com/perl6/roast/commit/1c4b...b5855fR114 00:55
timotimo vendethiel: we just changed how the "semicolon form" of classes works 01:01
we now require a "unit" in front
because that's harder to confuse people with who expect "class Foo;" to be a stub declaration 01:02
rjbs Hm, so I can pass (message => 'exact string') but not (so far): (message => /act str/) 01:09
or => * ~~ /act str/
Odd, because Test.pm has $got ~~ $v 01:12

no...
01:24 jack_rabbit left
rjbs I'll update my gist. 01:25
gist.github.com/rjbs/7aa7adfc92c68cb6217a
TimToady I thought throws-like wants a string to eval 01:26
rjbs So, I think I'm matching your example's use of message=>/.../
throws-like:$code (specified as either something Callable, or as a something to be EVALled)
the passing of a sub is definitely okay, it works if I replace the /..../ with the exact string
01:28 vendethiel joined
rjbs "Code object coerced to string" is a bit odd to me, too 01:28
TimToady oh, heh, remember that /x is default now, except it's actually mandatory, so your space disappears unless you :s
so try /'terminated early'/ 01:29
or /:s terminated early/
or /terminated.early/ 01:30
rjbs Okay! I wondered if that was related, actually, but the output of the test was so weird that I discounted it. :(
TimToady++ # knows his perl! that was it
so you can put modifiers to the regex right inside the opening /? 01:31
Anyway, great, thank. That error message is kind of a mess, though.
TimToady in fact, you may not put them at the end anymore
that's Too Late
rjbs I would've expected: s:/.../
but I guess that would be a s//// with nomodifiers?
TimToady well, it'd have to be rx:s or so
rjbs rx is the new qr? 01:32
TimToady m: use Test; throws-like('1e0 / 0', *.say, message => rx:s/by zero/,"oops")
camelia rakudo-moar 55ed38: OUTPUT« 1..3␤ ok 1 - '1e0 / 0' died␤Divide by zero␤ in block <unit> at EVAL_0:1␤ in any <unit-outer> at EVAL_0:1␤ in block at lib/Test.pm:443␤ in sub subtest at lib/Test.pm:272␤ in sub throws-like at lib/Test.pm:470␤ in block <unit> a…»

TimToady yes, rx:s works
rjbs Cool. Thanks, again, I really appreciate your and #perl6's patience as I putz around blindly. 01:33
TimToady but for :s you can also put it inside, like (?x:...) in Perl 5
rjbs Ah, ok.
I'm going to stick to outside, as otherwise I don't trust myself to see it.
TimToady just remember that m// is different, and evaluates immediately, so you have to use // or rx// to produce a Regex object 01:34
m: use Test; throws-like('1e0 / 0', *, message => rule { by zero },"oops")
camelia rakudo-moar 55ed38: OUTPUT« 1..3␤ ok 1 - '1e0 / 0' died␤ ok 2 - right exception type (Whatever)␤ ok 3 - .message matches ␤ok 1 - oops␤»
TimToady or use rule {}, which implies sigspace
it's sort of unfortunate that rule implies :s, but token implies :r 01:36
yes 01:42
rx is the new qr
we don't call it qr because regexes are strings, so it's wrongish to say it's "quoted" 01:43
*aren't
my n't key is going haywire again...

lizmat good *, #perl6! 10:08
FROGGS hi lizmat
[Tux]: I've seen the same I::P5 issue yesterday when testing CURLI
lizmat FROGGS: at the hackathon after the OSDC.no, I discussed this briefly with pmichaud
he came up with the idea of not having a single CURLI "database" 10:09
but rather a master index, (always read at CURLI init)
and another "database" for each installed distribution
I'm warming up to that idea more and more 10:10
FROGGS I was under the impression that you have CURLIs per location
so, one for site, one for home etc 10:11
lizmat yes, you would
and then per location, per distribution, another database
FROGGS so every location has its database and CURLI object
lizmat yes
FROGGS per dist?
installed dist?
lizmat and each installed distribution inside that would have a "database" as well 10:12
FROGGS why that?
lizmat well, a handy accessible version of META6.json (not necessarily in JSON )
I see the following advantages:
1. the init time for a CURLI would decrease significantly, as it would not have to load all of the installed dist data 10:13
FROGGS 1) does not hold
lizmat 2. only modules that you actually use, would get loaded: CPU win and memory win
FROGGS that is also not true
lizmat ?? 10:14
FROGGS because to know what dists you have to care about you have to know what these dists provide
and you dont know what dists provide without looking at their information
lizmat well, maybe the master index should contain only the "provides" information, aka the keys you'd expect in a -use- statement 10:16
FROGGS so the MANIFEST file we have now is basically what you called master index, but we don't have duplicate information for that stored in extra databases
ahh
we could have a provides and files index (which maps to .candidates and .files)
lizmat which would punycoded point to the info *that* needs
yes
FROGGS that sounds sensible 10:17
lizmat and I would also think that you would only need the provides, as the files are secondary *after* a module is loaded, no ? 10:18
FROGGS lizmat: if you run a script 'foo' from path, you need files first 10:19
or if dist Font::Awesome just provides a .ttf file, and you app wants to get that shared resource only 10:20
lizmat wouldn't you have to "use Font::Awesome" first ?
FROGGS depends on how we expose %?RESOURCE I guess 10:21
I mean, the scripts do: CompUnitRepo.files('foobar', :name, :auth, :ver)
lizmat I would think you need to have *some* Perl hook to expose the .ttf 10:22
FROGGS and you can do that with font files too
lizmat to have a %?RESOURCE, implies a package in which that lives 10:23
and that implies loading a module to me
FROGGS yes yes
but you get your hands at the files via CUR.files
dalek kudo/nom: 652c245 | jnthn++ | src/core/Exception.pm:
Ignore warnings when printing exception.

Not a prefect solution, but actually getting an exception message out is better than choking over warnings issues while producing it.		 10:24
jnthn .tell TimToady did something about the warning while printing exception bug 10:25
yoleaux jnthn: I'll pass your message to TimToady.
lizmat FROGGS: I'm not sure having to access CUR.files is long term a good solution 10:26
I would need to think about that some more
FROGGS lizmat: IMO that this is a very good way to query the repositories 10:27
lizmat I would be afraid of false positives
FROGGS lizmat: you need to keep in mind that there is also panda that needs to get its hands on information
dalek c: b53d3e0 | (Steve Mynott)++ | lib/ (2 files):
fix 3 typos
lizmat FROGGS: yes, I know too well, recently :-) 10:28
FROGGS lizmat: there can't be any since that is the only way to query our repositories that we also use internally
lizmat in any case, are you happy with the current state of CURLI to have a rakudo* after next week's release
? 10:29
FROGGS if I fix panda properly, yes, I think so 10:30
lizmat cool!

rjbs Yes, works... sometimes!
jnthn You get a choice.
rjbs a choice?
jnthn You can use --> *or* returns
DrForr Hadn't realized they were equivalent.
jnthn Well, --> is meant to also let you declare a variable to assign into that will become the return value, by spec. 14:02
However, we don't do that bit yet, so they're equivalent.
Heh, and I probably meant "by design" since I'll bet we've know spec tests for the variable thing... :)
rjbs Hm... 14:03
arnsholt I think people have mostly settled on using the returns trait for top-level stuff, but for embedded signatures (like callbacks) you have to use -->

TimToady and we don't want to frustrate people like rjbs++ 16:20
yoleaux 10:25Z <jnthn> TimToady: did something about the warning while printing exception bug
TimToady I will not always be around to spot the issue
basically, we can either disallow /two words/, or dwim it, but the current situation is not friendly 16:24
FROGGS yeah... 16:25
TimToady how often to people put spaces into alnums with the express intention of NOT matching a space there?
maybe matching hex: /aaaa bbbb ccc/
but it seems like a rare thing to want to do 16:26
if it's a warning, we need a way of disabling it
jnthn I'd lean towards disallow (or maybe warning); the dwim's behavior is confusing when there's also sigspace which allows it but with a different behavior.
TimToady well, it could be dwimmed with same behavior, \s+ 16:27
jnthn I fear that'll create more confusion that it solves... 16:28
TimToady "Fear is the mindkiller."
if a warning, how to disable... there #OK, and maybe explicit :!s 16:30
both ucky
rjbs To be fair, the thing that frustrated me was the error message, not the behavior. 16:31
I didn't get "<message string> doesn't match /regexp thing/" but some totally weird other thing that made it unclear that I'd even got the syntax of the test right, let alone the semantics. 16:32
But I cede that plenty of people may get confused by the /x-ness. But that might be just fine.
TimToady I thought that error was from the 1st sub argument
so an independent failure mode 16:33
(which also needs fixing)
skids Hrm, some recent change seems to allow Failures to escape from throws-like and hit DESTROY.
TimToady well, that's why I put the DESTROY message in, to catch those failure leaks :) 16:35
the biggest one turned out to be multidim subscripts, but I know there are others
some of them are probably places that should be sunk, but aren't, but this does seem like that kind of leak, offhand 16:37

ugexe is there a way to use a ::($rulename) in a regex where if $rulename fails it just moves on to the next match instead of dying? 17:16
17:18 zakharyas joined
TimToady I don't understand what you mean by ::($rulename), can you give an example? 17:20
within a regex, / <$rulename> || <otherrule> / oughta be close to what you want
well, might need to be <$::($rulename)> or so 17:21
<$rule> probably requires a hard ref 17:22
17:22 raiph left
ugexe i want to use the result of a match as a rule 17:23
so if <address=alpha> matched abcd, then <::($address)> would act like <abcd> 17:24
$<name>=["Connection"] ':' <.OWS> <Connection> <- this is the type of thing im trying to refactor (the rulename = the previous match) 17:26
having 'Connection' twice feels wrong
(elsewhere there is a token Connection {}) 17:27
s05 says a leading :: indicates a indirect subrule, and lists / <::($somename)> / as an example 17:29
17:29 cognominal joined
TimToady you might need a ~ in there somewhere to stringify the old match 17:29
m: my $somename = 'alpha'; say 'abc' ~~ /<::($somename)>+/ 17:30
camelia rakudo-moar 652c24: OUTPUT«｢abc｣␤»
TimToady the mechanism seems to work, at least with a built-in method 17:31
are you doing this in a grammar, or trying to do it with lexical scopes?
ugexe in a grammar 17:32
TimToady have you tried <::(~$somename)> ?
ugexe not yet, but im about to :) 17:33
TimToady or stringified the earlier match somehow?
ugexe no... i think in my head i assumed that since im matching a literal string that the match was a string for some reason
TimToady you'd think a symbolic ref would stringify by default...

TimToady seems to stringify there too, so dunno where you're going rwong
you're not trying to use $<thatthing> inside as a reference to a previous regex, are you? 17:38
you have to save it in a temporary if you want to do that, like I did with $alpha, since $0 would refer to the current regex, not the previous
p6 regex don't rely on string interpolation like p5 regex do 17:39
or use ::($oldmatch<thatthing>) if you saved the previous match in $oldmatch 17:40
ugexe i get Method '' not found for invocant of class 'Zef::Grammars::HTTP::RFC7230'. The <::($rulename)> is from an inherited rule, but i dont think that would affect it. Running with grammar::tracer/debugger dies with the same message too so ive lost the easy way to step through it :(
TimToady how are you loading $rulename, and is it in an appropriate scope to be visible? 17:41
well, it must be visible or it would give a compile-time error 17:42
so must be a lifetime/dynamic issue
ugexe its inherited from another class (a role really). 'is ExtendedRules'
if i hard code the rule in its fine
hard code the rule as in <Rule>
TimToady you can't inherit a variable, so I don't know what you mean by the variable $rulename is inherited
is your code literally <::($rulename)>? 17:43
ugexe but <$rulename> is a token that is inherited
TimToady what sets $rulename?
ugexe in $<name>=["Accept"] ':' <::($<name>)>, $rulename is $<name>
in $<name>=["Accept"] ':' <Accept>, this works. token Accept is inherited 17:44

camelia rakudo-moar 652c24: OUTPUT«｢alpha:f｣␤ name => ｢alpha｣␤»
TimToady yes, known bug
rakudo doesn't set up $/ unless you poke an extraneous {} in there
ugexe how does {} work around it?
ah
thanks, id have never figured that out 17:48
TimToady everyone keeps hoping someone else will fix this :)
so I guess I'd better put it on my personal todo list
I suspect the actual solution is to not really use a Match object for refs to $/ inside a regex, but fake access into the current Cursor instead, rather like STD does 17:50
ugexe and here i thought it had to do with :: discarding the previous match or something. must have been thinking of ::: 17:51
TimToady that :: has nothing to do with backtracking, just symreffing 17:52
same as ::($foo) outside in normal p6
on top of which, :: and ::: aren't implemented yet in rakudo...
FROGGS I was thinking about implementing ::, but I dunno where to start 17:54

serialize CURLI database to "bytecode" instead of json

This has several reasons. The most important one is that this let use get rid of the performance penalty which json gave us. When hundreds of dists were installed the startup time increased to over 5s easily. Now the startup time for -e1 is unchanged (lazy deserialization ftw), and using (and therefore locating) modules is more effective. Also a benefit of not having to deal with json is that we can stick Distribution and CompUnit objects in our database, which reduces our CURL code a lot.		 19:57
jnthn hah, I'd never quite imagined lazy deserialization would end up being useful *here* also :D 19:58

TimToady but it's a constraint on what function you can bind, even if it's not currently enforced

japhb raydiak: You have an array of things that are either Foo or Bar, where Bar inherits from Foo. You want to call a method (defined in Foo, enhanced in Bar) on all elements of the array, and for Bar elements to use its extra settings. How do you do that cleanly? 23:06
(And if your answer is a type test on each element, assume the array is filled with 56 different types all inheriting from a common base, and try again.) 23:07
masak japhb++ # good explanation
TimToady plus, assume some of the arguments are aimed at a single layer, while others are aimed at most or all of them
japhb .? allows automatically ignoring if an object doesn't have a method, but it is the named argument magic that allows us to do it if the method exists, but subtypes have more settings 23:08
