lizmat

well, it feels to me that the implementor is not being tormented anough for the features that users can use

00:00

jnthn

Tough.

The whole reason it was specified this way was to give us a chance to optimize things.

lizmat

if it is supposed to be only for dynamic variables, what use *are* the pseudo packages then?

jnthn

OUTER:: isn't restricted in that way

00:01

lizmat

doesn't that have similar issues ?

jnthn

No, because we can lexically see it is being used

And make sure to preserve enough information to use it

00:02

lizmat

because at compile time you can already resolve it, is what you're saying ?

jnthn

Yes, or at least, at compile time we can see there's a use of OUTER:: and so not discard information we need in order to do late-bound lookups by name

00:03

lizmat

what about CLIENT:: ?

especially if that's a different compilation unit ?

00:04

jnthn

Also would be restricted, though I think we'd want to make sure that sub decls are counted as implicitly dynamic, since much of the purpose of it is to find the operator definition of the CLIENT

00:05

I think for modules that really want to monkey around, we can 1) provide a pragma for setting the default dynamicity of variables, and 2) providing the pragma export mechanism I previously discussed.

00:07

lizmat

pragma export is something we really need :-)

jnthn

Then P5tie could just say "well actually, make everything `is dyanmic` so I can find and tie it by name"

lizmat

anyways, I'm too tired to think very straight....

so see you tomorrow&

.ask AlexDaniel Can you tell if the Cro::WebSocket test failure is a Rakudo regression? (I assume there is some Blin magic to do that, but I've forgotten the incantation.)

00:09

yoleaux

japhb: I'll pass your message to AlexDaniel.

jnthn

sleep time, 'night o/

AlexDaniel

japhb: Cro::WebSocket – AlwaysFail

00:09Z <japhb> AlexDaniel: Can you tell if the Cro::WebSocket test failure is a Rakudo regression? (I assume there is some Blin magic to do that, but I've forgotten the incantation.)

AlexDaniel

not a regression, I think…

ohh, one is really easy

02:54

and is already fixed… cool :)

AlexDaniel found another module with .grep: { /foo/ }

jnthn

lizmat: Currently working on a `dynamic-scope` pragma; I'll for now have it switch on when we use /^P5/, but that means we should just be a pragma export mechanism away from a proper solution

11:05

lizmat: Can confirm this already fixes P5tie :)

11:08

lizmat

jnthn++

jnthn wonders where the right place for pragma tests is...

11:12

Hm, maybe just with the kind of feature it affects

Geth

rakudo: 871cbefc6f | (Jonathan Worthington)++ | src/Perl6/World.nqp
Add a `dyanmic-scope` lexical pragma

This allows for specifying that:
  * Without args, all variables declared in the scope the pragma applies
   to will be automatically `is dynamic`
  * With args, the named variables declared in the scope the pragma
... (6 more lines)

11:29

rakudo: 88c46676c5 | (Jonathan Worthington)++ | src/Perl6/World.nqp
Apply the dyanmic-scope pragma for `use P5*`

Thus extending the workaround we already have in place to keep those working until the proper mechanism for them to use is available. This fixes the P5tie regression reported in #2616.

11:30

roast: 600827736d | (Jonathan Worthington)++ | S02-names/dynamic-scope.t
Add tests for `dynamic-scope` pragma

jnthn

Huh, it didn't report the commit adding that to spectest.data

11:33

nine just bought a Comma subscription for work!

tell patrickb I did. Will hopefully find some time for it later today

do we have an up-to-date blin or toaster run for the release?

Geth

rakudo: 9295616422 | (Elizabeth Mattijsen)++ | src/core/Date.pm6
Make sure $!daycount is nulled on subclasses of Date

The problem was that subclasses of Date do not use the fast-path creation of objects, but go through .bless. This missed an important part of the initialization of $!daycount. Fixes R#2615

12:05

jnthn

timotimo: AlexDaniel++ did blin yesterday, which is where we have these various reports from

12:07

lizmat

m: class A is Date { }; my $a = A.new(q/2019-01-18/); dd $a.succ

Type check failed for return value; expected Int:D but got Int (Int)

timotimo

i see all the committable invocations, but no gist with actual blin results at the moment

jnthn

Ah, I didn't see that either
