I want to make something like Midnight Commander (mc) in raku. What TUI modules are available?
I'm aware of Terminal::Widgets, but that's still WIP 03:52

tbrowder hi, is there an easy way to sort the k (key) part with ‘for %h.kv -> $k, $v’? 12:10
m: my %h= %( a => 2); .say($k => $v) for %h.kv 12:14
camelia ===SORRY!=== Error while compiling <tmp>
Variable '$k' is not declared. Perhaps you forgot a 'sub' if this was
intended to be part of a signature?
at <tmp>:1
------> my %h= %( a => 2); .say(⏏$k => $v) for %h.kv
tbrowder m: my %h = %( a => 1); for %h.kv -> $k, $v { say “$k => $v” } 12:17
camelia a => 1
antononcube @tbrowder Make pairs first, sort by key, then take .kv per pair. 12:18
Something like %h,pairs.sort(*.key)».kv . 12:19
tbrowder like adding a “.sort” in there ^^
yes, that’s what i always do. 12:20
antononcube Ok.
tbrowder but i see lizamat adding .sort in lots of surprising places, and also dwarring 12:21
antononcube Then, what you are asking is to have ability to sort Maps.
They might be using "Hash::Ordered" or similar.
tbrowder i guess so. i think you can use .x on anything that produces a $_ 12:22
antononcube This seems to work: 12:24
cdn.discordapp.com/attachments/633...bd827&
librasteve m: my %hash=(c=>3,a=>42,b=>7); say %hash.sort(*.key)
evalable6 (a => 42 b => 7 c => 3)
Raku eval (a => 42 b => 7 c => 3)
antononcube Well I meant this code: use Hash::Ordered; my %h is Hash::Ordered = b=> 3, a => 1; %h.sort.Hash.kv 12:25
lizmat Hash.kv is unordered
librasteve tbrowder: maybe I don't understand ... but .sort(*.key) seems to answer your question
antononcube @lizmat I guess I did not read the descript of "Hash::Ordered". 12:27
librasteve m: my %hash=(c=>3,a=>42,b=>7); say %hash.sort
evalable6 (a => 42 b => 7 c => 3)
Raku eval (a => 42 b => 7 c => 3)
tbrowder let’s see: 12:29
m: my %h=b=>2,a=1; for %(%h.sort(*.key)).kv -> $k, $v { say “$k => $v} 12:35
camelia ===SORRY!=== Error while compiling <tmp>
Unable to parse expression in curly double quotes; couldn't find final '”' (corresponding starter was at line 1)
at <tmp>:1
------> t(*.key)).kv -> $k, $v { say “$k => $v}⏏<EOL>
…
lizmat tbrowder: you're sorting a hash, then turning it into a hash again and the expect the order of the sort to be preseved? 12:36
m: my %h = :1a, :2b; .say for %h.sort(*.key).map(*.kv.Slip) # but it feels like a very roundabout way 12:38
camelia a
1
b
2
tbrowder no, i’m not surprised, i pulled the trigger before engaging brain
lizmat m: my %h = :1a, :2b; for %h.sort(*.key).map(*.kv.Slip) -> $k, $v { say "k = $k, v = $v" }
camelia k = a, v = 1
k = b, v = 2
12:40 tirnanog joined
tbrowder thnx, but my eyes glaze over with map and grep 12:40
antononcube <tbrowder> "[...] pulled the trigger before engaging brain" -- If you pull the trigger long enough, then the trigger pulls you.
lizmat m: dd (a => 42).kv
camelia ("a", 42).Seq
lizmat m: .say for (a => 42).kv 12:41
camelia a
42
librasteve took me a while to "get" this subtlety ... we are not the only ones - stackoverflow.com/questions/560670...d-using-kv 12:42
m: my %hash=(c=>3,a=>42,b=>7); for %hash.sort {say .key, .value}
Raku eval a42 b7 c3
evalable6 a42
b7
c3
librasteve ^^ this way sidesteps your question - passes each pair into the for loop 12:43
tbrowder ah, a trick that works 12:44
lizmat or use destructuring, which I think makes the most sense in this case:
m: my %h = :1a, :2b; for %h.sort(*.key) -> (:$key, :$value) { say "key = $key, value = $value" } 12:45
camelia key = a, value = 1
key = b, value = 2
lizmat note the variable *must* be called that
or further destructure: 12:46
m: my %h = :1a, :2b; for %h.sort(*.key) -> (:key($k), :value($v)) { say "key = $k, value = $v" }
camelia key = a, value = 1
key = b, value = 2
tbrowder ok, thnx to all. need to put all that in my keeper notes!
lizmat: did you see PR with 2 good tests? 12:48
lizmat you mean github.com/lizmat/Git-Status/pull/10 ? 12:50
librasteve my %hash=(c=>3,a=>42,b=>7); for %hash.sort.>>.kv -> ($k, $v) {say "$k => $v"} 12:51
evalable6 a => 42
b => 7
c => 3
librasteve lizmat: I like yours ... but a bit too much typing for my taste 12:53
lizmat m: my %h = :1a, :2b; for %h.sort(*.key) { say "key = $_key(), value = $_.value()" } # shorter 12:54
camelia ===SORRY!=== Error while compiling <tmp>
Variable '$_key' is not declared. Perhaps you forgot a 'sub' if this
was intended to be part of a signature?
at <tmp>:1
------> a, :2b; for %h.sort(*.key) { say "key = ⏏$_key(), value = $…
lizmat m: my %h = :1a, :2b; for %h.sort(*.key) { say "key = $_.key(), value = $_.value()" } # shorter
camelia key = a, value = 1
key = b, value = 2
librasteve question - is it necessary to use .sort(*.key)? my testing shows that *.key is the default for Hashes anyway 12:55
lizmat actually, what you see is the default behaviour of Pair cmp Pair
.sort(*.key) does a Schwartzian transform under the hood 12:56
YMMV :-)
librasteve The type-agnostic comparator; compares two Pairs. Compares first their key parts, and then compares the value parts if the keys are equal. <== that's what we want isn't it
.oO ... guess we can add another Wikipedia page to the tally en.wikipedia.org/wiki/Schwartzian_transform 12:58
tbrowder lizmat: yes to PR question 13:10
lizmat tbrowder: left some comments 13:12
tbrowder ok
will fix 13:20

tbrowder lizmat: i think the test.yml it's the way it should be, with @ugexe's suggested way 15:18
lizmat but why would we test zef in the CI of Git::Status ? 15:20
that will just run the tests again?
tbrowder it's not testing zef, or are you talking about the --debug option?
he --debug option shows more info in case there's a problem is my understanding, esp testing on workflows 15:21
github testing which we don't have a lot of control over without giant pain points 15:22
but it's easy to remove if you want. i put it in because i use that all the time now 15:24
lizmat the "run-tests" script already runs all of the tests 15:25
so what is the goal of running "zef --debug install ." ?
that it will install?
but isn't that implicit in the successful running of the tests? 15:26
I'm just trying to understand *why* you'd want to do that, in case there is some reasoning I missed
tbrowder oh! i got lost in the weeds trying to understand it, so i just kept it. please change the PR test stuff to what is correct
*understand run-tests that is 15:27
lizmat it's an alternative to testing: it's pretty quiet if all goes well, and very verbose when tests fail 15:28
tbrowder fine with me for sure! 15:29

ugexe you would test with `zef install .` instead of some test script or manually invoking the tests yourself to ensure everything precompiles and actually installs 17:25
just running tests without also installing is not a good practice. and running the tests separate from the install means you have to precompile everything twice. so i recommend using `zef install .` to test your code in CI 17:26
17:31 jpn joined
ugexe "but isn't that implicit in the successful running of the tests?" - No 17:31
tests can pass yet encounter precompilation errors on install 17:32

SmokeMachine I'm having some troubles releasing my old module `SeqSplitter` on fez... I have released a version 0.0.1 (I already had that version on p6c) and then released 2 more version (0.0.2 and 0.0.3) but it seems raku.land only see the 0.0.1 (raku.land/zef:FCO/SeqSplitter). Any idea what I'm doing wrong? 17:50
now it's there! 17:51
