2020-08-24T16:59:00Z #raku <tbrowder> jjmerelo: i used the safari browser which i rarely use and still don't see the change on the nativecall page.

JJMerelo

.tell tbrowder it's under a CDN, sometimes changes take a bit of time... I can deploy today again just in case.

07:45

tellable6

JJMerelo, I'll pass your message to tbrowder

MasterDuke

is ^^^ expected? only if the first letter on the rhs is a 'z' will it create all the multi-char entries in the range

09:46

lizmat

hmmm...

09:49

MasterDuke

looks like it should be going through this block github.com/rakudo/rakudo/blob/mast...#L164-L169

09:50

lizmat

looking at the code, it appears it turns it into ... sequence if the lengths of the strings do not match

timotimo

coverable6: my @a = ("a" .. "yzz")[]; say @a[(^@a).pick]; say @a.elems;

09:51

coverable6

timotimo, and I oop! Backtrace: gist.github.com/1a352b13d1d60da3ae...85317ea420

lizmat

and *that* uses .succ until the string cmps greater than the right hand side

m: dd "z" cmp "yzz"

camelia

Order::More

timotimo

interesting

lizmat

so that makes it stop then

AlexDaniel

timotimo: which bot did you want?

09:52

lizmat

I'm *not* saying it should be that way, just describing why it does it now

timotimo

i did want coverable

since it shows you what lines are being hit by a code example

AlexDaniel

timotimo: ahh… yeah, I'll take a look later

09:54

MasterDuke

lizmat: makes sense (the explanation of what is happening). also interesting is the difference between a range and a sequence

09:55

where in this case the sequence is 100x faster

lizmat

because it does less?

MasterDuke

m: my @a = ("a" .. "za")[]; say @a[(^@a).pick]; say @a.elems; say now - INIT now

.. with [*] is the outlier here

timotimo

oh, is there a way to get coverable to not sort the hit lines so you get more like a trace?

MasterDuke

does coverable sort? don't remember now

09:57

lizmat

hmmm.....

timotimo

line 90 runs sort

MasterDuke

lizmat

MasterDuke: could you make an issue for the Range[*] case ?

10:00

AlexDaniel

did you fix it? :)

10:01

timotimo

looks like the problem was just not giving it a valid commit

AlexDaniel

ahhh

timotimo

and the problem wasn't reported at the earliest point for some reason

i'd put "my" into the regex with "sub" and "say" that finds out you're actually passing code instead of commit

10:05

AlexDaniel

timotimo: but github.com/Raku/whateverable/blob/...p6#L74-L78 ?

10:06

timotimo

yeah, could you imagine to-full-commit getting "my" "wrong"?

10:07

committable6: my say "hi"

committable6

timotimo, ¦my: «Cannot find this revision (did you mean “nom”?)»

timotimo

hmm

nqp: 04d53f0237 | (Patrick Böker)++ | src/HLL/Compiler.nqp
Fix `raku -V`

The rename of `Compiler.config()` to `Compiler.sysconfig()` failed to rename all uses. Also the naming is a bit unfortunate, as that method does not return the `SysConfig` object, but the build configuration. So just give it back its old name.
