grondilu Hello. Please look at this gist.github.com/grondilu/ebceff32e...fdb4516f24 and tell me what I am missing. 03:30
03:31 zetaaaa left
grondilu basically I'm trying to catch a pattern in a multiline string but the regex grabs all the trailing newlines. 03:31
m: say grammar { rule TOP { ^ <line>+ $ }; rule line { <.alpha>+ } } .parse: "foo\n" 03:37
camelia ｢foo
｣
line => ｢foo
｣
grondilu how can I extract "foo" and not "foo\n"? 03:38
03:39 ulipink joined
grondilu in a nutshell I want to parse a file with blocks of text separated by empty lines. 03:39
that can't work as I've tried if the regex catches trailing newlines. 03:40
guifa I would use token instead 03:42
or change <ws> to be \h
so 03:43
say grammar { rule TOP { <line> %% \n }; rule line { <.alpha>+ } } .parse: "foo\nbar\nxyz\n" 03:44
m: say grammar { rule TOP { <line> %% \n }; rule line { <.alpha>+ } } .parse: "foo\nbar\nxyz\n"
camelia ===SORRY!=== Error while compiling <tmp>
Missing quantifier on the left argument of %%
at <tmp>:1
------> say grammar { rule TOP { <line> %%<HERE> \n }; rule line { <.alpha>+ } } .parse:
guifa m: say grammar { rule TOP { <line>+ %% \n }; rule line { <.alpha>+ } } .parse: "foo\nbar\nxyz\n"
camelia Nil
guifa m: say grammar { token TOP { <line>+ %% \n }; token line { <.alpha>+ } } .parse: "foo\nbar\nxyz\n" 03:45
camelia ｢foo
bar
xyz
｣
line => ｢foo｣
line => ｢bar｣
line => ｢xyz｣
grondilu tries
grondilu fails 03:47

grondilu m: say grammar { token TOP { <line>+ %% \n }; token line { <.alpha>+ } } .parse: "foo\n\nbar\n\nxyz\n" 03:49

kathe Hello to everybody. :) 12:25
timo greetings
kathe I don't know if Mr Wall hangs out over here anymore. In case he still does: 12:26
I tasted "Pepsi" yesterday, and honestly, I liked it.
As opposed to my preference from ThumbsUp and Coca Cola. 12:27
The Pepsi people have made some changes to their formula,
as far as the Indian market goes. It is not as sweet as it used to be before. 12:28
Alrighty, bye to everybody, and I hope Raku not just survives, but also thrives.
Have a great time ahead. :)

librasteve o/ ... hi folks 14:13
turns out my JetBrains IntelliJ Ultimate subscription will expire on 13th Jan ... since I only use for non-commercial OSS development about 95% on raku, I would like to try and get a JetBrains IntelliJ Ultimate licence under the raku or cro projects ... 14:16
... here is the application form www.jetbrains.com/shop/eform/opensource
lizmat patrickb ab5tract is that something you can do ?
librasteve this says JetBrains can support your open source project by providing free All Products Pack and Team Tools licenses to use for the development of your project. If you are a project lead or a core contributor, please fill out the form below to request this support.
14:17 ulipink joined
there is some kind of licence www.jetbrains.com/legal/docs/toolb...pensource/ that the applier would need to agree 14:19
lizmat librasteve: from the legalese: "Customer may renew its Product subscription for another year by submitting a written request to JetBrains 30 (thirty) days prior to the end of the Subscription period." 14:21
feels to me we won't be able to fix before the 13th :-(
librasteve well, don't worry about my deadline too much --- I am raising this for the general benefit for any contributors who like an IDE with strong raku support but cannot afford the commercial subscription 14:22
also I get the feeling that the raku community maybe has a shot at getting on the JetBrains OSS partnerships - ie sponsorships (see other languages / framworks here www.jetbrains.com/community/opensource/) --- while we are not as big as those listed, we do have strong and active JetBrains Raku plugin project ... if the RSC things that's worth making an approach, let me know if I can help with writing a 14:27
proposal ...
lizmat looks like we have a point on the agenda in tomorrow's meeting :-) 14:28
librasteve nice 14:43
antononcube When I apply for the Ultimate Open Source program of JetBrains "online" I always get the automatic response that I do not qualify. Then I ask for human review and get the corresponding license granted within 1-3 days. 14:46
I think their automatic system checks for both history length and commits saturation of single repository (or three.) It did not allow (as far as I know) to apply with a set of multiple repositories that are active. 14:48
Again, that is the automated system. Human reviewers seem to "get it" very quickly. 14:49

[Coke] we only have custom code for date formatting, right? (can't pass a string like "HH::MM" somewhere?) 15:51
15:51 ulipink left
antononcube Format to print a date, or format to "ingest" a date? 15:57
...i.e. interpret a date.
lizmat HH::MM with 2 colons ? 15:58
[Coke] some languages have a set of formatting codes (probably last one I dealt with was oracle's sql) - the colons would just be passthrough, but if you have an "HH" in the format string, that's a 12-hour hour, etc. let me find the sql ref... 16:00
lizmat TIL :-) 16:10
[Coke] docs.oracle.com/en/database/oracle...1DAFC6D0A3 16:17
I think a full implementation of that would be nifty but is not needed for a first pass at the PROMPT var. 16:18

msiism [Coke]: Looking at your latest verison if the configurable Rakudo prompt. Looks good to me in general. 19:10
Though I think it would be a good idea to offer the actual name of the software corresponding to the language and compiler version, respectively, as well. 19:11
But cramming that into `\l` and `\v` might not be the best idea. 19:12
[Coke] there's a bunch of information under $*RAKU - let me know what you'd like to see. 19:22
m: dd $*RAKU
camelia Raku.new(compiler => Compiler.new(id => "E3372814772281C70E296626151E51AA68B35AB7", release => "", codename => "", name => "rakudo", auth => "Yet Another Society", version => v2024.12.40.g.633.df.2893, signature => Blob, desc => Str), name => "Raku", …
[Coke] m: dd $*RAKU
camelia Raku.new(compiler => Compiler.new(id => "E3372814772281C70E296626151E51AA68B35AB7", release => "", codename => "", name => "rakudo", auth => "Yet Another Society", version => v2024.12.40.g.633.df.2893, signature => Blob, desc => Str), name => "Raku", …
[Coke] m: say $*RAKU 19:23
camelia Raku (6.d)
[Coke] m: say $*RAKU.compiler
camelia rakudo (2024.12.40.g.633.df.2893)
[Coke] (somewhere there's info about the VM and its version also 19:24
There was discussion recently about putting the ansi codes in a lookup somewhere - if we had that in core, we could definitely take advantage and used named colors in the prompt instead of raw escapes. 19:25
msiism That would be great, yes. 19:27
So, as for names, I'd personally take Raku correspoding to the language version and Rakudo to the compiler version. 19:28
[Coke] so instead of just "v6.d" you'd expect "Raku v6.d" ?
or, I guess, "Raku (6.d)", since that's what we get above. 19:29
?
msiism I would probably expect that, yes, in whatever the official way of putting it is. 19:30
But then, some people might prefer not to see the name.
That's reasonable too.
19:32 ulipink joined
msiism Not sure if also having `\V` and `\L` ("with name") would solve this. 19:35
19:36 ulipink left 19:38 Aedil left
msiism Is there a particular reason you chose `v` for the compiler version? 19:38
[Coke] nope 19:39
I mean, I had a slight preference for the choices, but nothing super compelling, no 19:40
basically just trying to see if it worked, and then to give a target we could make suggestions at.
timo any ideas how to make the syntax to specify the prompt formatting less annoying to work with? maybe something like "whitespace means nothing" so you can space things out a little for example? 19:41
[Coke] also not meant to be exhaustive. Possible update: make index smarter when it's a subcommand.
Could make a little mini lang, sure
You might also be wanting PROMPT_COMMAND instead? 19:42
(which i didn't write (yet))
any REPLS with prior art to inspire also welcome 19:44
msiism Python's REPL has ways to set the prompt through some variable in… uhh… `sys` I think. 19:45
So, I think it would be useful to have lowercase `l` for only the language version and uppercase `L` for language name plus version. 19:46
If the version displayed alone is not surrounded by parentheses, which I'd say it shouldn't be, then the same should be the case when a name is also displayed. 19:47
timo and uppestcase L will give also the git commit in the version 19:48
[Coke] I would rather just show the output of the existing commands rather than do more post-processing, if that's possible.
the git commit is just part of the existing version if it's present?
timo it's in the $*RAKU.compiler output yeah 19:49
everything after the g
[Coke] I wouldn't add it in if it happens to be an actual release.
timo right, it wouldn't have it for a tag
[Coke] +1 19:50
I'll push something that does a basic version of \l vs. \L for feedback shortly
19:51 ulipink joined
timo committable6: 2024.6 say $*RAKU.compiler 19:51
committable6 timo, ¦2024.6: «Cannot find this revision (did you mean “2024.06”?)»
timo committable6: 2024.06 say $*RAKU.compiler
committable6 timo, ¦2024.06: «rakudo (2024.06)␤»
msiism I'd probably go with `s` instead of `v`. But that's just because the Unix shells I've used give you their name with `\s` in the prompt and use `\v` to provide their version number. 19:53
`\l` versus `\s` (language versus shell) makes sense to me in the Raku context.
19:55 ulipink left
[Coke] I like that we get \v(ersion) and \l(anguage). 19:57
msiism My idea was that "version" is the general term, and then there is a language version and a compiler/repl version. 19:58
[Coke] ... I also wonder if we should go with : instead of \ as the prefix to make it slightly more raku-like.
msiism As long as you can still put a literal colon into your prompt, that would work too. 19:59
ugexe might have been nice to called 6.c, 6.d, etc standards, i.e. std 20:00
[Coke] yah, that would be either :: or \: ... which is annoying enough that I'll leave it as is. :)
ugexe like with -std=c++11 -std=c++17
[Coke] would we want a combined "version" then?
msiism Displaying both the language and the compiler version? 20:07
[Coke] eh. user can write them both if they want both. 20:12
msiism Right.
[Coke] I may do a v. small set of the date formatting and move \t and \A to \d{HH:MM} or so. 20:18
msiism That would be an idea, yes. 20:24
There's probably some ISO standard on how to write those formats.
20:26 ulipink joined, apac joined
[Coke] If you can find one, that'd be helpful - otherwise I'll follow the Oracle SQL format 20:30
timo presumably the posix standard specifying the date program and maybe the C standard or again unix that specifies strftime? 20:31
20:31 ulipink left
msiism Yeah, you could use strftime format strings. 20:32
[Coke] www.man7.org/linux/man-pages/man3/...ime.3.html ?
msiism pubs.opengroup.org/onlinepubs/9699...ftime.html 20:33
That's probably the same.
[Coke] so something like \t (defaulting to %T) or \t{%H:%M} ?
msiism Sounds good to me. 20:34
The advantage of strftime format strings is also that they are all two characters long and you wouldn't need to type YYYY for the year. 20:35
timo pubs.opengroup.org/onlinepubs/9699...ftime.html strftime definition from i think POSIX.1-2008 20:36
msiism Oh, there's now a 2024 version of POSIX. 20:37
timo i'm not sure how to navigate posix standard versions
[Coke] timo: I am tempted to just roll the few I care about (hour, minute, second) - would you have a preference to actually just call strftime ?
msiism And here's the strftime definition from that: pubs.opengroup.org/onlinepubs/9799...ftime.html
timo: Older documents will hint at the latest one. 20:38
timo "issue 6: [...] are added for consistency with the ISO POSIX-2 standard date utility"
msiism Starting point for the latest is at pubs.opengroup.org/onlinepubs/9799919799/, apparently.
timo en.wikipedia.org/wiki/Austin_Group 20:39
msiism And that is issue 8, it says.
timo i was looking for the first version that has it, not the newest :D
newest was relatively easy to find. i guess that is the magic of this "austin group" who are working on "the one posix specification" 20:40
msiism :)
[Coke] Is there a way to call a formatter on an existing DateTime.now result? 20:44
I can pass it into the constructor...
lizmat .now takes a :formatter and :timezone argument 20:45
it may not be documented as such, but it does take it :-)
[Coke] I want to grab the time and then call formatting multiple times, not have to grab a fresh time for each format. 20:46
(I'm using .now(formatter) already, apologies)
Guess I can do it "manually" by poking the attributes. (which is how the formatter code is working anyway) 20:47
lizmat what are you trying to achieve? Better efficiency ? 20:48
just OOC
[Coke] doing piecewise printing of, e.g. hour/min/sec - don't want there to be a chance that the time flips a second between grabbing the pieces. 20:49
e.g. at 11:59:59 grab the hour, then it ticks over, then grab the minutes at 60, then I print 11:00
I don't *need* the formatter, I already have all the components, I realize. no worries. 20:50
timo i'd probably take now.DateTime and grab everything from that
lizmat .substr on the .hh-mm-ss output ?
timo instead of using the now sub to give me whatever with a formatter
[Coke] timo: exactly. I was just used to the formatter approach when I could do it all at once. 20:51
20:52 yewscion left

msiism Nice. 23:18
[Coke] Needs *13*? approvals? I assume we'll see some comments and have to chsnge some things. I addressed most of your concerns here, but I think not all 23:24
msiism I won't be able to take advantage of any changes all too soon anyway. The system I use has a 2-year-ish release cycle. 23:27
I might be tempted to build a more recent version of Rakudo from source, though. 23:28
[Coke] rakubrew makes that easy and also has prebuilt ones you can install
