moon-child how can I debug an infinitely hanging grammar? 08:36

MasterDuke trying changing the `*` in your TOP to `+`? 08:44
moritz don't think that's it 08:45
08:45 sour joined
moon-child moritz: doesn't look like any of them would be zero-width, though? 08:45
sour what parsing algorithm is used internally by the raku grammars?
that grammar looks like it's left recursive
moon-child MasterDuke: doesn't help
moritz sour: you'r onto it, I think
expr -> fn-call -> expr '(' ... 08:46
sour try replacing the first <expr> in fn-call with literal-str
again, i'm not sure if hanging is desired, but if left recursion is bad, that's where it's bad
moon-child ahh, I see
moritz Grammar::Tracer can help you debug, to answer the original question 08:47
<plug> www.apress.com/us/book/9781484232279 also contains some advice dealing with stuff like that </plug>

hi, does anyone know if DBIish can output the built sql query commands as text, not execute the actual query on the db? 13:55
13:55 soursBot left
bazzaar I'm just thinking it might be a useful function for debugging 13:56
the use case could be where using placeholders in a prepared insert query, and traversing a complicated data structure and populating the placeholders from different levels of the datastructure. 14:01
14:02 brtastic left 14:03 soursBot joined
bazzaar may also help to ensure data value glitches don't get pushed to db, a quick screening of the final text insert commands before doing the execute. 14:03

it's not worth doing it since nqp can change out from under you.

jdv79 should autovivication be a "last wins" type deal in a multi assign? 16:26
it seems raku does that but perl does not. i found perl's handling more DWIMy. 16:27
nopaste.linux-dev.org/?1318831 16:29
should i report that as a bug or is that intentional?
16:38 dakkar left 16:41 rbt left, rbt joined
jnthn I believe Perl's one eagerly creates on first touch (so just looking can vivify); in Raku that doesn't happen, but yes, if there's nesting in cases like this then it would vivify a different hash in the top key 16:41
konvertex m: <3 5 -2>.combinations.max({[*] $_}).say 16:49
camelia (3 5 -2)
konvertex m: <3 5 -2>.combinations.max({[*] |$_}).say

konvertex What happens here?
jdv79 so maybe a trap note in the docs but it'll stay the way it is?
jnthn jdv79: Most likely yes; I guess it's the trade-off of doing the other DWIM. It's not clear to me we can reasonably have both. 16:51
jdv79 ok, thanks! 16:52

melezhik Hi! github.com/melezhik/Sparrow6/blob/...6#L90-L157 22:18
Sparrow uses that code to run sub processes, if there is any way to disable buffering to make time stamps in log more sensible ? 22:19
for example here I see buffered log, and timestamps do not reflect real picture, because obviously zef test does happen immediately - github.com/ugexe/zef/issues/353#is...-637154222 22:20
So basically I am talking how to disable stdout/stderr buffereing when run process using Proc::Async 22:26
[Coke] docs.raku.org/routine/out-buffer ? 22:30
ah. if it's in a proc::async... I think you're going to get some buffering just because it's going through a Supply. 22:31
melezhik yeah, probably it's not buffering itself that concerns me most, but Sparrow waiting for something before it closes child process 22:33
may be it's not the case, but to see this I need first of all somehow disable buffering ... 22:34
[Coke] how do suppose to use out-buffer to deal with it? 22:35
jdv79 if its any help i think i've seen that when running zef in a docker build 22:36
just haven't cared to check it out yet

melezhik Never mind Sparrow 23:20
Sparrow waits something, it's just buffering
so I need to know how to manage size of buffering and flush it, when run processes through Proc:Async, if possible ))) 23:21
