newb2 Here's an easy one. In the perl6 REPL how can I run an external script.p6 to modify the perl6 environment? 00:36
Just as I can type "source .bashrc" at the shell prompt and the shell environment will be modified
00:37 mcmillhj joined
newb2 If you're wondering why, I find that the Readline bindings in the shell & in perl6 are by no means identical 00:38
So I need to issue Readline commands to customize the perl6 environment to set vars, bind keys, etc
So the question is how can Ido the equivalent of "source .bashrc" in perl6? 00:40
AlexDaniel maybe EVALFILE ‘smth.p6’ 00:41
japhb newb2: I'm not sure how global Readline's state is, but note that you can use modules in the REPL, and in fact a common trick is to set an alias for your version of the repl that calls `perl6 -M Module::With::My::Favorite::Stuff` so that it's loaded on REPL start
ugexe also require my-script.pl6
newb2 Yes but if I run a shell script in eg bash it doesn't change the environment unless Is source it
Is perl6 different? 00:42
ugexe what do you consider the "environment" in perl6?
00:42 mcmillhj left
newb2 when I set a binding with a headline function that is persistent for the session 00:42
s/headline/readline/
japhb Depends what you mean: are you trying to change the env vars that are passed on to child processes? Or just want to change the state of the running perl6? The latter is much easier in perl* than it is in bash, because perl does not do its normal business by spawning subprocesses all the time. 00:43
newb2 I want to customize the bindings in the REPL, and I have done it
But now I need to run a batch file that will make persistent changes 00:44
teatime www.cbc.ca/news/canada/british-colu...-1.4256694
newb2 Persistent that is for the rest of the session
japhb In other words, when you use a module in Perl, the *default* behavior is that it affects the current running Perl process; in Perl 6, it also tries to limit the scope somewhat to only the current lexical scope, but this works out usually to be what you meant in the REPL.

newb2 OK thanks will give it a spin .. :/) 00:44

japhb newb2: What is a 'session' in this context? In a single REPL, or every time you start the REPL in that current login session, or forever? 00:45

samcv what do you guys think the max number of codepoints per grapheme should be. currently, moarvm has a hard limit of 1024 00:52
m: ("\c[COMBINING ACUTE ACCENT]".ord xx 1025).chrs.say 00:53
camelia Too many codepoints (1025) in grapheme
in block <unit> at <tmp> line 1
00:53 mcmillhj joined
geekosaur ultimately it should probably be dynamic. practically, you'd be justified in a fairly low limit like 15 00:54

ijneb How do I do an 'or' expression in givens 01:24
in a when
like when 'N' || 'n' { }
AlexDaniel 'N' | 'n' should work 01:25
it will create a junction which will do the right thing
or maybe /:i n/
mmm /:i ^n$/
given $foo.fc { when 'n'.fc } # ? 01:26
samcv i was gonna say that AlexDaniel yeah
or even # when .fc eq 'n' if you don't know the case of the given 01:27
AlexDaniel when $_ ~~ 'N' || $_ ~~ 'n' # I suppose this should work too?
samcv or, when .fc eq 'N'.fc etc etc
01:28 mcmillhj joined
ijneb I was already doing that samcv 01:29
I need something like this: `when 'N' | $stage == 1
is it possible to do that?

of course this will not work if the logfile gets truncated or rotated in the meantime

i think i got , i am to use spurt. 07:25
07:26 mcmillhj left
kannan but how to append the line to the same file? 07:26
snarkyboojum can you open the file in append mode? 07:28
.open(:mode<rw> :append) 07:29
I don't really know :)
07:29 epony left
jast spurt is a convenience thing to write a whole file at once. the normal approach is to open the file (in this case, probably in append mode), write things to it as needed, and close it when you're done 07:29
kannan is it same sybtax as open in perl 5, thats what results are showing. where to search sytax docs from within the installation for perl 6? 07:30
ok i think i found 07:31
examples.perl6.org/categories/cookb..._file.html
if i know there is a function 'open' in perl6, how to look it up in a documentation?
snarkyboojum I was looking at docs.perl6.org/type/IO::Handle#method_open 07:32

jast it's funny, I can buy your book as an e-book for $19.99... or individual chapters for $29.99 each 07:38
moritz I know 07:40
that's a weird feature stemming from the fact that apress is part of Springer
jast oh, makes perfect sense, then
moritz and Springer tends to publish mightily expensive text books, where you do sometimes want to purchase a chapter chapter
07:40 mcmillhj left
moritz s:2nd/chapter/cheaper/ 07:40
jast yeah, I know all about expensive textbooks... fortunately that time where I needed many of them is all over :) 07:42
moritz jast: what did you study?
jast knowledge engineering and computer science, and later artificial intelligence which I quit early when I got fed up with not doing any actual work 07:43
moritz I did physics, and for the basic courses, the textbooks were kinda OK priced (or available in the library); stuff for my diploma thesis tended to be more specialized and much more expensive
jast of course some fields have even more ridiculously expensive books
moritz jast: ah good
snarkyboojum I'm pretty sure I just picked up the kindle version for $11.04 07:44

kannan do you think i should learn programming with perl6 first, everything seems to say 'learn python' or 'javascript' (and i always do the exact opposite, due to my nature, lol) 08:10
anyway its what i am doing :) 08:11
moritz snarkyboojum: for the Perl 6 Regexes book I'm creating a separate Docker image with stuff pre-installed 08:14
kannan i am seeing docs.perl6.org/routine/match#class_Str . If i want to do a IF condition, then there should be a true/false. [ IF match is ture, the do something]. but the syntax says the output will be the $pat only? 08:16
jast kannan: python and javascript have a lot more followers and there probably exist more python/javascript libraries at this point, but realistically the biggest danger is that if you start with Perl 6, eventually every other language will seem fundamentally lacking to you ;)
kannan jast : very good. i feel happiness with perl. maybe i will become a good coder some day. (its not required for me in my life really, but i want to) 08:17
snarkyboojum if you want to, then you probably will :)
08:19 araujo_ joined
jast kannan: "if" tends to be somewhat more flexible about the exact return type. in this case, "match" returns (Any) if there is no match, which is taken to be false 08:19
08:19 mcmillhj joined
jast also, you can use the smart match operator ~~ instead of the match method for more conciseness, example: 'abc' ~~ /x/ 08:20

kannan i am using the IO::Tailfile with react {} , this writes lines that match a pattern to another file. Should i use open($my-file-to-write, :a) inside the react {} and close when program exits (its never supposed to , i want to keep it running all the time) OR should the file be open in append mode PRIOR to the react{}. both are working, but i cannot see what the difference is.
i can open and close the file handle inside react, or just open once in append mode at start of program. which is correct way? 10:33
sena_kun kannan, I am not a professor, but I'd say that the second approach is better. This way you do less IO calls(how much less depends on how often your react block is fired). 10:37
kannan sena_kun : that is what i also thought (and did). thanks. 10:38
sena_kun There may be some pitfals, for example, on power outage file system doesn't save the rest of the file(or not) or something like that, it depends on what you need, I guess, but the second seems better for me. 10:40
kannan now the written file can be handled concurrently by another script at the same time ? write.p6 writes and read-write.pl reads and writes , both same file. this will not present any problems i hope? 10:43
sena_kun There will be problems, because of concurrency. :/ 10:44
kannan i see.
sena_kun You need access synchronization.
10:45 nattefrost left
sena_kun kannan, see en.wikipedia.org/wiki/Readers%E2%8...riter_lock for further explanations. 10:45
kannan no, i will write each line to its own file and close the file insdide the IO write script. there is a way to scan dirs for new files and handle them from the other read-write script i hope. 10:46
10:46 nattefrost joined, Zoffix joined, rindolf joined
Zoffix gfldex: understood. Thanks. 10:46
gfldex kannan: you can do that but expect it to break on windows or on network file systems. 10:47
Zoffix kannan: you can accomplish that using advisory locking with filehandles: docs.perl6.org/type/IO::Handle#method_lock
kannan basically what i want to do is analyse security events in a log file and ban IP addresses with iptables when needed. the IO will write only lines with offending IPs bassed on the value of SecurityEvent=something
gfldex kannan: i would write them to a log file and a fifo 10:48
or some other form of IPC
kannan the log file is already generated, by asterisk pbx daemon. i am looking for a way to handle this as fail2ban isnt working so well. 10:49
Zoffix kannan: open() gives you an IO::Handle object. So you could do my $fh = open 'foo', :a; then when writing do $fh.lock; $fh.put: "Stuff"; $fh.close; That'll give exclusive lock; when reading do $fh.lock: :shared; $fh.slurp (or whatever other reading method you wanna use) and then $fh.close. If you don't wanna close then do $fh.flush; $fh.unlock (no need to .flush on reads) 10:50
kannan ok i have to read up on each of this first. thanks gfldex and Zoffix 10:51
Zoffix .lock will basically sit and wait for the other script to finish writing. This way two or more scripts can work on the same file without stepping on each others' toes. 10:54

Ulti that reddit thread is actually really quite interesting for every bogus "but how do I type things" complaint there are people seeing the upside to unicode being supported in programming for the programmer 11:11
to date unicode support only ever meant for the applications we create its really weird no one has considered how it might be worth dog fooding given we all constantly use myriad maths operators 11:12
gfldex I didn't like unicode operators at all until I made it easy for me to write them. :)
Ulti I didnt until I realised ctrl+cmd+space was a context menu everywhere in macOS 11:13
I still dont write them purely out of fear but perhaps I should change that
especailly as I use set operators a lot and those look so nice
and it would be nice if reading code helped me get better at reading algo papers 11:14
timotimo this is basically exactly the same situation as { and } not being available on old keyboards and therefor we got trigraphs in C 11:15
gfldex I found that enclosing filenames in ⟨⟩ is quite nice as it will help me spot filenames with trailing or leading whitespace and works with files that contain quotes. (And yes, those exist.)

Zoffix kannan: you're likely looking for $filename.IO.lines».split(",").flat».split("=", 2).flat -> $key, $value is copy { $value .= substr: 1, *-1; } 12:40
Take lines of file, for each of them, split on ",", then on each of the resultant values, split on "=" with at most 2 chunks made. Then the $value .= substr business is to remove the quotes from $values

Zoffix Any time. The "»" thing is called a hyper operator; it calls the method that follows on each of the items in the list. The `.=` thing is equivalent to $value = $value.substr, except you don't have to type $value twice. 12:43

13:02 mr-fooba_ left
Zoffix It's sensitive to them because there's another form of the hyper operator, e.g. like @foo «+» @bar, that has an infix operator inside of it, and it thought you meant that form and forgot to put the infix 13:02

raschipi_ kannan: It's also important to note that youn _cannot_ put whitespace anywhere in Perl6. Lot's of things change meaning depending on whitespace. 13:04
Zoffix Some things are sensitive to you. Another place where it matters is between a sub name and parentheses. `foo(42, 100)` means "call sub `foo`, giving it two positional arguments 42 and 100", while `foo (42, 100)` means "call sub foo with 1 positional argument, which is a list of two integer"

sena_kun bdmatatu, you likely want to wait a day or two until original/fork situation with Net::ZMQ will be resolved. As soon as it become true, ping me here and I'll write you a migration guide or someting. 17:13

sena_kun if seems that author abandoned Text::Markdown. How bad it would be to publish a fork into ecosystem with different `auth` to let another modules use it instead? 17:41
Skarsnik there is a repository in the eco for this, but if you want to take over it works too I guess 17:42
sena_kun what repository? 17:43

ennio Hello! if anyone is interested in vscode... I played a bit with the language server libraries provided by MS, and I managed to have Perl 6 syntax checked without too much problems 20:05
the code is here: github.com/scriplit/vscode-languageserver-perl6
I think it would be nice to have an implementation of the language server protocol in Perl 6 directly, but this seems out of my reach :) 20:06
sena_kun ennio, cool. You may want to add it to perl6.org/whatever/ list.

P6steve hi - anyone know how can I write a signature that has a list of allowed Types for each positional (for infix sub), please? 20:34
raschipi_ P6steve: What about using a multi? 20:35
20:35 geekosaur left
P6steve raschipi - I'm already using multi - but 4x operators, 3x types (Distance, Real, Str) is a lot of repetitive code 20:37
raschipi_ right, what about type classes? 20:38
Or declaring a type that is a superset of the allowed ones?
20:39 cdg joined
P6steve do you mean something like class AllMyTypes is Distance is Real is Str - that'd probably work 20:40
20:41 geekosaur joined
raschipi_ You can also use a type variable (:: sigil) and then check to see if it's an acceptable type later (::T ~~ Distance|Real|Str) 20:43
Or you can use a subset: (Any $var where Distance|Real|Str) 20:46
mspo neovim has a language server plugin 20:47
[Coke] multis for types, private untyped sub they dispatch to...

samcv timotimo, i think we may want to stop collapsing strings when we do regex on them 23:24
m: my $a = 'aaaaaaaaaab'; my $b = 'a' x 999999 ~ 'b'; say $b ~~ /$a/; say now - INIT now
camelia ｢aaaaaaaaaab｣
7.6077099
samcv my $a = 'aaaaaaaaaab'; my $b = 'a' x 999999 ~ 'b'; use nqp; say nqp::index($b, $a, 0); say now - INIT now
m: my $a = 'aaaaaaaaaab'; my $b = 'a' x 999999 ~ 'b'; use nqp; say nqp::index($b, $a, 0); say now - INIT now 23:25
camelia 999989
0.205195282
samcv so that takes only .2 seconds if we don't collapse it
especially now that we have knuth morris pratt algorithm for _all_ strings, i think it may be a good idea?
23:27 skids joined, devmikey left
TEttinger did those print on top of each other? 23:29

samcv 999989? 23:30
for some reason literal regex takes a ridiculous amount of time
even when i disable flattening the haystack 23:31
it must be doing a bunch of crap other than just indexing it. i mean it's just a literal
23:31 mcmillhj joined
MasterDuke heh, try interpolating a literal string into the regex, multiple times slower 23:32
samcv hmm? you mean like <$this> ? 23:33
m: my $a = 'aaaaaaaaaab'; my $b = 'a' x 999999 ~ 'b'; say $b ~~ /<$a>/; say now - INIT now
camelia ｢aaaaaaaaaab｣
19.30805550
MasterDuke that's worse even than just $this
oh ha, that's what you first did 23:34
samcv well yeah since it has to create the regex
MasterDuke but yeah, <$this> is the slowest
samcv yeah since it's not literal
basically like eval
MasterDuke yep
samcv not sure why literal is so slow. but i don't know how the regex compiler works... 23:35
23:36 mcmillhj left
samcv 4.5000660 secs with flattening and disabling flattening it takes 4.7 secs 23:36
which is sad since nqp::index is practically instant
23:38 snarkyboojum left 23:39 mst left
samcv and case insensitive regex is 5.09 seconds. why is just plain literal so slow.. 23:40
how do i look into this and see what ops it's running? i mean i tread --target=mast but i cant find `MAST::Op index` anywhere. does it refer to some precompiled bytecode or something that actually has that op? 23:41
samcv is angry i made the nqp::index op faster but regex is still so slow...
MasterDuke look at --target=optimize 23:43
samcv nope not there either 23:44
nothing with 'index' in it at all
23:45 Cabanossi left
MasterDuke what code are you looking at? something with nqp::index? or a regex? 23:47
samcv yeah
23:47 Cabanossi joined
samcv it's a regex 23:47
not sure how it would work without using index at all though...
or index from end or something
MasterDuke i think the actual regex engine does it 23:49
see the QAST::Regex?
samcv so the regex engine doesn't use nqp::index? 23:50
MasterDuke it might, but maybe it does it at runtime? 23:52
could stick an fprintf(stderr, ...) in index and see 23:54
Ulti is anyone else bummed that the "atomic" operators are not on the periodic table www.ozonehouse.com/mark/periodic/ 23:55
samcv well i mean it does use nqp::index. but. it must do other ops too 23:59
