I have no plans currently to go through the existing infrastructure and
rename things. I'm not intimately familiar with the code in Rakudo
Star, and prefer to not touch what isn't broken. If references are
found and can be easily fixed, I'll gladly look into it, though. Of
course, patches to help out are much appreciated as well!

Also, please note that the language is called Raku, the compiler is
Rakudo.

Rakudo Star v2020.01

[Patrick Spek via perl6-users]

Hi everyone!

Just now I've sent an announcement to perl6-compil...@perl.org, to
notify people that I've made a first non-rc release of Rakudo Star. For
those of you that use Rakudo Star, this may be a good time to try out
the latest version! The files are available from https://dist.tyil.nl:

- https://dist.tyil.nl/raku/rakudo-star/rakudo-star-2020.01.tar.gz
- https://dist.tyil.nl/raku/rakudo-star/rakudo-star-2020.01.tar.gz.asc
- https://dist.tyil.nl/raku/rakudo-star/rakudo-star-2020.01.tar.gz.checksums.txt

I've not had many people to test things, but the rakudo spectest
succeeds on all my machines, and I've been using it on my own machines
for a couple weeks now, so I have no reason not to believe this release
will work.

Do note, however, that I only use, and therefore test, on GNU+Linux.
This release does *not* contain a .msi (for Windows users) or a .dmg
(for Mac users). If anyone would like to help out by building those
files, please do not hesitate to reach out!

If you have any questions on how to install this (on GNU+Linux or
otherwise), please reply to the mailing list and I (or other people,
especially for Windows and Mac users) will do my (or our) best to help
you out.

Any feedback on how to best communicate these releases is also very
much appreciated.

Lastly, I do not have access to the sources of https://rakudo.org/ (as
far as I'm aware), and can therefore not update that website to mirror
the release files, nor update its documentation. If anyone knows who to
contact for this, please let me know.

Thanks Yary!

I'm glad it works for you without too much troubles. I'm unsure what
exactly goes wrong with the NativeCall stuff, nor what might be
affected by it.

Perhaps a Raku core dev can tell us more about this?

Any additional testing is very much appreciated! I'd like to have
someone that can generate a .dmg as well if possible, though, so we can
continue to deliver some form of binary variant for mac users.

Hi David,

The default parameter handling of Raku requires you to use an "=" sign
between the option name and value. Additionally, the option needs to be
before any positional arguments. Try running it as follows:

raku script.raku --layout='1+kk' apt

As for the ability to add it several times, I believe using an @ sigil
instead of a $ sigil should work, but perhaps someone else has spotted
an issue that I missed here.

For Mac and Windows, perhaps, but the release is similar as it always
was for GNU+Linux. And I'm mostly aiming for that since that's what I
use (and also what I can test). Hence, I need people to verify they can
make binaries for Windows and Mac (and actually do it as well) before I
can continue.

I never intended to make a "binary" release. I intended to make a
Rakudo Star release, and I personally don't care if that'd be a binary
or source. In the case of GNU+Linux, it's a source release.

Looking at the archives on rakudo.org[1], there are .dmg files, which
are packages for Mac I believe. Though, I'm not using a Mac, so please
tell me if these are just Mac specific archives to be unzipped.

The tarball I've created requires compilation in addition to just
"unzipping", though. I'm not sure if that's a problem for regular Mac
users. If it's not, I guess the Mac part is not an obstacle for getting
a release out.

I wrote automated tests for GNU+Linux using GitLab CI, which are being
introduced in this release. However, I can't "test" making a Windows or
Mac installer, and then test if they also work. I have no idea how
installers for either of these platforms are made, and I also don't
think I can use GitLab CI for either of those platforms.

I agree with you, especially the "good" part. Since Rakudo Star has to
work for more people than just me, I'm a little hesitant to move
quickly with it. I can't test it on Mac or Windows, for instance, but
there are users on both platforms, and having a good but old release is
probably better for them than new but broken.

However, if the community would rather I mark the current -rc1 as a
proper release, I can do that too. I just don't want to harm the
community at large.

It used to be on a three month interval, and I'd like to go to a two or
three month interval myself as well. I can try to make that happen once
I know for certain that the current release process works.

Hi Marc,

I've been working on Rakudo Star 2019.11-rc1, which is available from
my file server[1]. However, I don't think I've made a regular (non -rc)
release out of it, as I'm waiting on Naoum to test the release for
Windows first.

I don't see it listed on the releases page[2] on the GitHub repository
either, can you tell me where you saw this?

StackOverflow is a Q&A-style website, that's their intended flow. If
you want more of a conversation-style help, this mailing list is a much
better option to go towards.

What you find offensive isn't set in stone for others. There's also a
lot of value in ensuring everything is constructed in a similar way.
This enables people to not have to learn each person's style and
grammar choices all over whenever they are looking for an answer to a
problem of theirs.

They may be a negative to you personally because you dislike being
corrected on grammar, but they're not "negative issues" for the
community at large. However, this very ML seems to be the kind of thing
you're looking for, no?

Re: Rakudo Star 2019.07.1

[Patrick Spek via perl6-users]

The problem is clearly with the Linenoise module, I'll have to look
into that and see if it's something I can fix.

The path name you see is "an implementation detail" of Zef, I've been
told before. I have no clue how it actually calculates them, and no
idea where to find any documentation on that. That is something I
cannot fix, and as far as I understand, there's no way this will be
changed on the Zef side of things.

I'm not sure what you mean with "-n vs .n for sub-version ids". If this
is causing issues or unclarities while trying to get Rakudo Star
installed, I'll need some additional information in order to see if
this is something I should fix or even can fix.

Rakudo Star 2019.07.1

[Patrick Spek via perl6-users]

Hello everyone,

I've seen people ask about 2019.07.1 in multiple avenues, myself
included. Since there was little response, I've set out to build it
myself. The first results have been made, with a PR on the Rakudo Star
repository to fix a number of issues.

Additionally, I've uploaded the 2019.07.1 tarball to my servers for
people to test[1]. Those looking for a newer version can download this
variant, and see if it works for them. If anyone spots any issues,
please let me know, either through this mailing list, the GitHub
repository[2] or the GitLab repository[3]. I'm trying to track all of
these places, and try to resolve all issues people find.

I plan to also release a 2019.10 version of Rakudo Star before the end
of this year, but whether that's viable depends on the number of
severity of the issues people may find.

I hope we can continue the Rakudo Star releases on a regular basis in
2020!

Re: perl6 for web development

[Patrick Spek via perl6-users]

It's a library for making a web application. One could also make a
framework out of it, if they wished to do so.

Jonathan has made this distinction in the past, referring to Cro as a
library explicitly, as opposed to a framework, as a framework is
(usually) highly opinionated. Cro is not.

That said, Cro has been quite smooth sailing for me, so I too would
suggest you taking a look there. There's also Bailador[1], which is an
actual framework for creating web applications as well. There's also a
tutorial for it on YouTube[2], if that's interesting to you.

Rakudo Star 2019.07

[Patrick Spek via perl6-users]

Hi everyone,

I'm using Rakudo Star to get Perl 6 on my machines. However, it seems
that the latest release is 2019.03, which is half a year old by now. Is
anyone working on a 2019.07 (or different number) release right now, or
are there currently no maintainers for it?

If it's the latter, can anyone point me to some documentation (if there
is any) on how to make a Rakudo Star release? If it's easily automated,
I can look into setting one up (at least for GNU+Linux users).

Beauty is in the eye of the beholder. While I'm much more proficient
with PCRE than P6CRE, I do find the Perl 6 variants to be much cleaner
and easier to understand when reading regexes of others.

If you find that there's a lack of documentation explaining things
clearly to you, that'd be an issue to solve in the documentation. This
takes a lot of effort, and if you would be so kind as to improve it
where you think it's needed, it would be a great help to everyone (we
can't really see how or where you're looking for what, after all).

you use the method form of say.

Re: LogP6 not working as I expect

-BEGIN PGP SIGNED MESSAGE-

Aha!

That works for me!

I don't particularly need it to be a constant, I just used constants
before to make sigil-less variables. I generally don't use `my \foo`
because I don't like how instantiation and use differ (one uses the `\`
sigil, which is no longer afterwards).

But it works for this particular instance, and is also used in their
own documentation. I didn't know the `constant` would differ in a way
like this.

Thanks for the help!

LogP6 not working as I expect

[Patrick Spek via perl6-users]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Hi all,

I'm trying to use LogP6 in one of my projects, but it's not working the
way I was expecting it to work. Presumably I'm overlooking something
simple, but I can't seem to figure out what or why. I have the
following code:


use App::CPAN::Repositories::Migration;
use Terminal::ANSIColor;
use LogP6 :configure;

unit module App::CPAN::Bin::Migrate;

filter(:name(''), :level($trace), :update);

constant Log = $?MODULE.^name.&get-logger;
constant MigrationRepo = App::CPAN::Repositories::Migration;

#| Undo the latest migration
multi sub MAIN (
  Bool:D :$down!
) is export {
  CATCH {
when .message ~~ / "relation \"_migrations\" does not exist" / {
  $?MODULE.^name.&get-logger.warn("why have you forsaken me");
  dd Log;
  Log.warn("No migrations left to undo");
  exit 1
}
  }

  my $last = MigrationRepo::last();

  MigrationRepo::down($last);

  say "Ran downgrade migration {color("bold")}{$last}{color("reset")}";
}


When running the program, I see the output "why have you forsaken me",
but not the output "No migrations left to undo". I added the `dd` call
to ensure that the `Log` constant is available, which it is. Why is the
log call of `Log.warn()` not being shown, but the
`$?MODULE.^name.&get-logger.warn()` is?

Hi,

I've been using Perl 6 in my personal projects to create an IRC bot
(using IRC::Client), a number of modules, and currently trying to set
up a new mail environment with a management API built with Cro.

At work, I've used Perl 6 to deal with DMARC notifications from Google.

In my experience, it allows me to write out my thoughts to working code
with very little effort, and still keep it readable.

I believe Stretch is Debian 9, so you would want to try out
https://github.com/nxadm/rakudo-pkg/releases/download/v2018.09/rakudo-pkg-Debian9_2018.09-01_amd64.deb
as the deb of your choice. You should be able to install it with `dpkg
- -i`, however, I believe it requires root powers in order to do so.

If you have Docker as an option, there's the `rakudo-star` image
available as well.

When all else fails, remember that a VPS nowadays ranges from 1 to 10
euro a month, and then you get root access to the machine. This might
be the least effort to get you going.

A grammar to provide substitution

[Patrick Spek via perl6-users]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

Hi all,

I'm trying to substitute parts of a string, and thought this might be a
good use of a grammar. Sadly, grammars aren't my strong suit, so I
thought I'd ask the wider community for help. Maybe you guys know an
even better solution than using a grammar here.

So, consider a string, "Here be a $(placeholder), for $(purpose)
purposes.". I want to be able to put that into a sub, along with some
Pairs, and get a string with the placeholders replaced back.

my Str $input = "Here be a $(placeholder), for $(purpose) purposes.";
my Str $output = format-string(
$input,
placeholder => "placeholder",
purpose => "testing",
);

dd $output; # "Here be a placeholder, for testing purposes."

The `format-string` sub would call the grammar and apply the actual
substitution, and that's where I need your help. I am not quite sure
how I would implement the grammar (and presumably it's actions) to do
what I want.

Thanks in advance for your help!

Patrick Spek

Re: start up delay?

If you're writing a runnable script in Perl 6, I would recommend to
*always* use a MAIN sub[1]. If you're using that, you can easily
achieve the precompilation as well, with 1 line of code less.

You'd have your code in lib/Your/Program/Main.pm6:

sub MAIN (
# You can let Perl 6 handle arguments here
) is export {
# Program code here
}

Next, the script that you actually run would be in bin/program, and
contain the following code:

use lib "./";
use Your::Program::Main;

This should give you all of the Perl 6 MAIN goodness, and a faster
program.

Re: return code?

I'd gladly help you get your first module published.

First off, you'll need to have a META6.json describing which files your
module will provide, and which dependencies it needs. You always will
need this json file, even if you have no dependencies.

Additionally, you will probably want to move the module files into a
lib/ subdirectory, as this is the standard for Perl 6 modules to live
in.

Your README.md could use a little extending as well, with information
on what problems it solves, how people can install it, but most
importantly, some examples on how people can use it. Many people also
add their license information in the README file, which I'd recommend
as well.

On the matter of licensing, your module currently is not licensed,
which means in most legal jurisdictions that it is not freely usable. I
am not a lawyer, though, so I may be completely wrong. I'd still
recommend you use a free software license to clear out any doubt, so
people know what they can and cannot do. I'm a personal proponent of
the GNU General Public License, but you should check out
ChooseALicense[1]. This site can help you pick a suitable license for
your code.

For some shameless self promotion, I have a module that can help you in
creating new modules: Assixt[2]. You can install it with zef:

zef install App::Assixt

Once installed, you can create a new module skeleton directory using

assixt new

It will ask you a couple questions, which it will use to create a
correct META6.json file for you. If you're planning on making more
modules, you can configure some default values for a number of these
questions with

assixt bootstrap config

Once you've created the new module skeleton, change to the new
directory and add the files you want to have added:

assixt touch class Command
assixt touch class Command::Result
cp ../old-dir/Command.pm6 lib/Command.pm6
cp ../old-dir/Command/Result.pm6 lib/Command/Result.pm6

The assixt calls will generate skeleton class files, and update the
META6.json to reflect these new files. But, since you already have the
actual files, you can just cp them into the new directory to take the
place of the generated skeleton files.

Once you've done this, make sure everything still works. I would
recommend adding some tests[3] as well. You can generate empty test
files in the right directory with

assixt touch test 

Assixt will have made a default Travis[4] configuration as well, so you
can enable automated testing on each commit that you push to Github. I
personally prefer GitLab, so there's also a GitLab-CI configuration
available by default. The GitLab-CI tests run *much* quicker, as there
is no need to install Perl 6 as a seperate action.

So, to reiterate, you should:

- - Put your files into the right locations
- - Have a META6.json
- - Add a license
- - Add some tests (and actually run them!)

Once all this is done, you're ready to publish your module. You can
either add them to the Perl 6 ecosystem repository[5], or upload them
to PAUSE[6]. Adding to the ecosystem repo is simply adding an entry
through a PR. I personally prefer PAUSE, which is what I'll cover here
for you.

You'll have to request a PAUSE account on their website[7]. This can
take a couple minutes up to a day or two before these requests get
processed. It looks more scary than it actually is, so just pick a
fancy username and mention that you want to contribute your Perl 6
modules to the community.

Once you have gained access to PAUSE, you can upload your module. The
easiest way to do this, is using Assixt again. When you're in the root
folder of your project, run the following:

assixt bump
assixt dist

The first command will "bump" up the version number. You can not
replace an existing version on PAUSE (and you shouldn't do it outside
PAUSE either), so you will have to increase the version number before
each release.

The second command will create a module distribution. This is just a
tarball that contains the files that other users will need to use your
module. Some files will be filtered out by Assixt, since they are
unneeded and would just bloat the distribution (such as
the .git, .gitignore and other such files). Assixt will also tell you
where it saved this distribution. You need to know where it was saved
to continue to uploading the distribution:

assixt upload 

Assixt will ask your username and password for PAUSE, and attempt to
upload it for you and store it in the right location. If your username
or password is incorrect, uploading will fail. You can just retry it in
that case.

If you're doing this more often, you can shorten the past three steps to

assixt push

This will basically run bump, dist and upload in one go. I prefer to
explain them all seperately so you know what's going on first. This
also helps you to understand that you can just rerun the upload command
if only that step failed on the push command.

I get the idea that you're trying to get a list of lines with the

@ReturnAry = split "\n", qqx ( curl $TimeOutStr -L $Url -o
$FileName; echo \$\? );

You can use the lines[1] sub for exactly this. Similarly for this line

for @ReturnAry[ 0 .. @ReturnAry.elems - 3 ]  -> $Line

You can use the head[2] sub to write it as

for @ReturnAry.head(*.elems - 3) -> $line

Also, on the

$ReturnStr += $Line

If you're trying to concatenate a string, you should use the ~ instead
of the +, so it'd become

$ReturnStr ~= $Line

No problem!

To be precise, -e can be easily remembered from "evaluate" (which I
think is also what it actually stands for).

It's not that it particularly dislikes it, but you have to think about
it in what the options do, and what you want to accomplish.

In a regular Perl 6 script, you'd also have to consider the order in
which you do a similar thing. First, you need to make sure the include
paths are correct, so the module can be found. Then, you have to `use`
the module, so that you can access the subs and classes it exports.
Finally, you want to let it run some piece of code that gets you where
you want to go.

This is what -I, -M and -e do, respectively, when ran as a one-liner
from the shell.

You're missing `-e` here, it should be

perl6 -I. -MRunNoShell -e '( my $a, my $b ) = RunNoShell("ls \*.pm6");

For further clarification, the `.` after `-I` indicates the directory
that is being added to the paths Perl 6 checks for libraries that are
being used. Hence the `.` is needed to indicate the current directory.
I'm not sure if `-I` arguments get appended or prepended to the list of
paths.

The `-e` is for the expression that is to be run. Otherwise, it'll try
to open the argument as if it were a filename, which is why you get the
"no such file or directory" error.

For this, there's `rmtree` in the `File::Directory::Tree` module. It is
referenced in the docs: https://docs.perl6.org/routine/rmdir

> Also, does Perl6 have a built in recursive mkdir
> equivalent to LINUX's `mkdir --parents path`?

Also in the docs here: https://docs.perl6.org/routine/mkdir. This
behaviour you're looking for is the default behaviour of `mkdir` in
Pelr 6. To quote from the docs:

The < > syntax is a bit like qw<> from Perl 5. You'll get a List (or
Array, not sure which type exactly from it. So



is a list with two elements, "myfile1" and "myfile2". If you want to
use a variable, you can just provide it with one or more variables:

chmod 0o755, $myfile
chmod 0o755, ($myfile1, $myfile2)
