xinming_ SmokeMachine: I just backlog'ed, and I lost the answer, how do we temp the table name, Could you please answer it again? thanks. 04:33
SmokeMachine: Now, I need to resolve a problem, where multiple views are created and I need to select views(tables) based on selection. 04:34
SmokeMachine: Also, How do we do group by in Red?
SmokeMachine xinming_: `is temp`?
xinming_: what’s the query you want? 04:35
xinming_ SmokeMachine: Not temp table
I mean, change the table name dynamically for the model 04:36
SmokeMachine .^table = “new-name”
xinming_ SmokeMachine: Somethign like; SELECT c1, c2, c3, COUNT(*) FROM tb1 JOIN tb2 ON tb1.id = tb2.id GROUP BY tb1.c1, tb1.c2, tb2.c1 04:37
SmokeMachine: Thanks.
SmokeMachine: I grepd the source, it doesn't seem to have clear example on doing group-by thing correctly.
especially involes .join-table + .group-by, I don't think distinct will work either. ;-) 04:38
SmokeMachine xinming_: yes... I don’t think there is a way of doing that by now...
xinming_: a way of grouping is using classify... 04:40
xinming_: maybe a .classify using Red::AST::Function... 04:44
xinming_: something like: `... .classify: { .c1, .c2, Tb2.c1 }, :as{ .c1, .c2, Tb2.c1, Red::AST::Function.new: :func<COUNT>, :args<*> }` # not tested code 04:49
xinming_ SmokeMachine: BTW, is it possible to specify columns to fetch for a model? 04:50
SmokeMachine: With views, if we don't include the column some data won't be calculated
in DBIC, We have .search(..., { columns => [qw()] }) thing 04:51
SmokeMachine: I think, if Red can fill all these needs, It'll be the killer ORM in raku. ;-)
SmokeMachine xinming_: in Red you can just return the wanted columns... 04:52
xinming_: `Model.map: { .col1, .col2 }` will only “calculate” those 2 columns 04:54
xinming_: is that what you wanted? 04:56
xinming_ SmokeMachine: Nope, What I mean is, returns the whole object, but will die when we try to access unfetched columns 04:58
It's the same as normal model objects, but partially filled.
my @rows = Modle.^all(:columns[<c1 c2 c3>]);
This way, the ResultSeq will be kept, we also have the whole object, with speed. 04:59
BTW, the is-rsclass doesn't work. I'll record these, when you back to computer, We'll discuss those. :-) 05:00
SmokeMachine That’s a good idea... 05:01
Please, open a new issue, I’ll take a look on the is rs-class ASAP 05:02
xinming_ `temp Model.^table = "new-name"` will return error: Can only use 'temp' on a container 05:03
SmokeMachine xinming_: But do you think that should die when accessing a not fetched param? Why not fetching it on the fly? 05:04
xinming_ SmokeMachine: Because that hides too many things underneath, When people specify columns, They know what they are doing, So dying is sensible behavior. 05:05
automaticallly fetching will cause tons of automatically fetch underneath, where, when people uses column limit to enforce the "limit", We shouldn't too smart on this.
SmokeMachine xinming_: colabti.org/irclogger/irclogger_lo...10-31#l190 05:08
xinming_: that makes sense... but maybe add a :fetch option for the case you change your mind and want to fetch that... 05:10
xinming_ SmokeMachine: what irclogs should I check? 05:12
SmokeMachine Sorry, wrong link... let me search for that again... 05:14
tony-o .tell xliff the problem with your updated gist is your rule. it tries to parse that as a code block rather than matching your sym. i wouldn't be surprised if the infix ~~ is also screwing with it in some way. altering it to just find a matching '{' '}' without the before works for me (and is more sane than requiring it to be EOL/EOS) 05:16
tellable6 tony-o, I'll pass your message to Xliff
SmokeMachine I meant this one: colabti.org/irclogger/irclogger_lo...10-31#l190 05:17

xinming_ SmokeMachine: Is the log answer to `temp Model^.table = "new-table"` name? 05:45
SmokeMachine Yes 05:56
Sorry, I can’t try it out with out my computer, but I tried to search on the logs to find how to do that... 05:57
Does anyone knows if something automatic is running more than 100 tests on Red in less than 6 hours? 06:09
I’m getting this on Red tests:
And it seems to be this: www.docker.com/increase-rate-limit...tm_budget= 06:10
Odd... does any one know anything about that? 06:11
xinming_ SmokeMachine: ^alias is different from `temp Model.^table = "abc"`; where ^alias("") will set the value permanently, where temp auto restore the old value. 06:25

xinming_ SmokeMachine: I also have other ideas, that I think should allow user to generate table name on the fly. As table expression is also usefull. 13:10
in postgresql, user can run sql functions to generate a table with arg. 13:11
13:14 Black_Ribbon left
SmokeMachine xinming_: any suggestion for the syntax? 13:18
xinming_ Nope, Buut will think about it. :-) 13:19
SmokeMachine xinming_: I’m also planning to add some new stuff on Red... I’m planning adding .^update-supply, .^create-supply and .^aggregation-supply. All of them will receive Supplies... 13:20
And the .^aggregation-supply will also receive a Callable 13:21
xinming_ SmokeMachine: BTW, can we have a temp sollution to make `temp Model.^table = "new-name"` work? 13:22
SmokeMachine That way it would be easy to “summarise” a supply on a db...
xinming_ SmokeMachine: What are these supplies used for?
I mean, after user create the row? the Supply will have things? 13:23
SmokeMachine xinming_: so if your code, for example, is a Kafka consumer, you can easily put that on a db to easily access that... 13:24
xinming_ Now, `temp Model.^table = "blabla"` will raise error:
Can only use 'temp' on a container 13:25
SmokeMachine xinming_: not, the opposite... the supply will populate the database...
xinming_ I also tried `Model.table = "blabla"`, I got error, Cannot modify an immutable Str (table_name_provided)
SmokeMachine: not that clear to me ATM. :-) 13:26
SmokeMachine xinming_: a supply with the changes on the database we already have with .events 13:27
xinming_ I read in MetamodelX/Red/Model.pm6, the table method is rw.
SmokeMachine xinming_: why the .^alias haven’t done the trick? 13:28
xinming_ I just can't figure it out, why it'll be the string.
13:28 lucasb joined
xinming_ SmokeMachine: What does .^alias do? 13:29
SmokeMachine xinming_: created a new model based on the given one
xinming_ SmokeMachine: So, something like Model.^alias("new_table_name").^all.map({ ... }), right? 13:30
13:30 stoned75 joined 13:31 andrzejku left, andrzejku joined
SmokeMachine xinming_: yes, something like that... (I don’t remember the exact params it needs) 13:32
xinming_ SmokeMachine: When you gave me the url, I thought you were proposing the new api for Temp table features
will check the source
SmokeMachine: It needs :$base, :$relationship, :$join-type 13:35
SmokeMachine: Doesn't work, will need to pass :$base 13:41
I actually `temp Model.^table = "blabla"` easier to understand. as people know how to point select to another table. 13:43
I actually think* 13:44
SmokeMachine xinming_: I agree... 13:45
xinming_ We need to enable some easy tricks for people to use
the .^alias needs all 3 args to be passed. 13:46
SmokeMachine xinming_: doesn’t that work without the temp?
xinming_ without temp, I got error, Cannot modify an immutable Str(table_name_provided)

xinming_ SmokeMachine: I had the `temp Model.^table = "new_name"` 14:02
I find the issue, will send the patch.
SmokeMachine Great! What was the issue?
xinming_ -multi trait_mod:<is>(Mu:U $model, Str :$table! where .chars > 0 --> Empty) { 14:03
+multi trait_mod:<is>(Mu:U $model, Str :$table! is copy where .chars > 0 --> Empty) {

xinming_ SmokeMachine: How do we define multiple column to sort please? 14:29
sort(*.col1) is understandable, If we need 2 columns, col1 DESC, col2 ASC
How do we specify this?

.sort: { .col1, -.col2 } 14:31
stoned75 hi. I'm looking for Bool.value method definition. I am not able to find it...

stoned75 on the enum type yes, but on one of its enum-pair ? 20:55
m: enum foo <a b>; say (a.pick(True), a.pick(False));
camelia ((a) ())
timotimo pick takes as argument "how many to return" so your True and False are used as numbers 20:56
m: enum foo <a b>; foo::.keys.pick.say for ^5 20:57
camelia b
timotimo m: enum foo <a b>; foo::.keys.pick.raku.say for ^5
camelia "b"
stoned75 here your are picking the enum's keys, not an enum-pair
20:58 benjif joined
timotimo what do you mean by enum-pair? 20:59
m: enum foo <a b>; foo::.enums.pick.raku.say for ^5
camelia No such method 'enums' for invocant of type 'Stash'. Did you mean any
of these: 'elems', 'Num'?
in block <unit> at <tmp> line 1
timotimo m: enum foo <a b>; foo.enums.pick.raku.say for ^5
camelia :b(1)
stoned75 I was using True/False in my example, only to illustrate that , in the end, pick (and roll btw) on an enum-pair is only about producing an empty list (for pick(False)) or a singleton list containing the enum-pair key (for pick(True))
with enum foo <a b> 'a' is a enum-pair 21:00
m: enum foo <a b>; say a.pair 21:01

notagoodidea raku.land is neat but I miss the option to reach the repo of the module? or is it just to show the readme from them? Also, does it only contain modules from the CPAN? 22:17
JRaspass git is planned, and adding a link to the repo will be trivial, good idea
the plan is to have the provides down the side and render the pod from each one, like metacpan 22:18
but atm only .md is supported and only README, Changes is also ingested but just dumped at the bottom of the page atm 22:19
jdv79 is the public irc log working? i cant connect.
notagoodidea I don't know metacpan (and the perl env in general), I will look after to get the frame of reference.
jdv79 anyone know who runs it? 22:20
JRaspass toolchain gang i presume?
added dist repo link to the roadmap :-) 22:23
notagoodidea thx :)
JRaspass oh sorry i thought you asked who ran metacpan, not the irc logs 22:24

22:26 dataange` left
JRaspass Ah right we have a unmerged VERY WIP PR for rouge github.com/jjatria/rouge/tree/raku-lexer 22:27
it doesn't handle all of raku's grammar yet 22:28
it knows some builtins like say, but not die, and methods aren't highlighted yet, e.g. raku.land/cpan:JJATRIA/HTTP::Tiny 22:29
notagoodidea Ah, because I am on a issue on skylighting (github.com/jgm/skylighting/issues/114) trying to get raku merged in it. 22:30
The contributors that create the Kate style syntax seems to have covered a lot of ground. 22:31
JRaspass ah cool, i find vscode's annoying when working on raku, it will highlight foo("bar") but get confused by foo('bar')
also it doesn't understand a raku shebang :-(
still calls the lang perl6 in the dropdown
22:32 Kaiepi joined
notagoodidea The idea is that if raku is merged to skylighting, I get it in any program that use it. neuron for sure, pandoc also I think. 22:32

notagoodidea it can output html too but the output may not be the most friendly to integrate from what I see. 22:38

JRaspass i might just fix it now ;-) its cro templates don't like Any values, they die when trying to escape the value 23:00
and some dists have null description

JRaspass now to fix the bug where raku.land/cpan:LEMBARK/FindBin-libs dies :-P 23:12
notagoodidea Hum, is there a way to indicate a empty value in an hash at declaration? 23:18
JRaspass Nil? 23:19
notagoodidea a => Nil?
JRaspass yeah or :a(Nil) :-P
notagoodidea m: my %a = foo => Nil, bar => "baz"; say %a; 23:20

notagoodidea mm, I want to convert a seq <as foo foo in bar bar as foo2> to an hash with <as in> as keys. I tried by split but because of the order when convert to Hash, the first pair as => "foo foo" is erased by as => "foo2". 23:51
leont rotor? 23:52
(or maybe I misunderstand your question)
What is the result you're looking for? what would the whole hash be? 23:53
notagoodidea <as foo foo in bar as foo2> => {as => [foo foo foo2], in => [bar]} 23:54
leont gather/then would work, but there may be a more elegant approach
MasterDuke .classify maybe
