I'm not a Mac user, but I've been struggling with another Rakudo
installation method for Linux and had similar problems. My solution has
been to install the binary code for linux by downloading it and putting it
in /opt.

Where are you getting the compiled code? Are you rearranging it in any way
before it gets to the final destination?

No reason to apologize, Todd. I had forgotten how much you were

Richard, there are many pod things that haven’t been implemented yet. I
have planned for a long time to do some more, but I think it’s best to wait
until the Rakuast branch is implemented on the master branch.

FYI, my early efforts were not as good as they should have been because of
my tiny knowledge of the grammar, and I know of many places where things
could be improved. Some of those places require, IMHO, a major redo of some
pod constructs. Not many folks were interested in pod, but that is changing
as Raku is maturing and getting new blood and interest.

You should feel free to work on anything that interests you.

Happy New Year!

Regarding the other questions:

1. I believe there are no reserved words for the '=begin/=end comment'.
However, nested comments I believe were an issue at one time but they
aren't now.

3. That depends on what you're doing. For example, currently the Raku
parser recognizes the nested pod code block, but it cannot handle pod codes
inside that pod code block.

If you just want to preserve whitespace using one of the two blocks alone
should be good enough.

Do you know how to write in Markdown or Raku POD?

Did you ever get your Github account?

IMHO, you (emphasis on YOU) should try to write a good draft we can comment
on, that means it would be best done on your own github account. Then you
can use the web interface and edit from any browser. Plus it's easy for
other users to peruse and comment on.

You have a reputation as the primo Raku Windows user (and Windows
professional expert), so you should run your draft up the old github flag
pole and we onlookers can suggest fine tuning edits.  ;-D

I'm on board with this. I also use App::Mi6 after I saw from Elizabeth how
much  it helps with module development (and maintenance!).

And from almost the beginning with mi6 I put my README.md source in a
docs/README.pod location so the mi6 usage would not interfere with inline
pod in my modules (but don't forget to change the dist.ini file
accordingly).

I agree that's a good idea, but I think it needs to be part of a larger
idea of module best practices in general, including testing, and maybe a
"green" check as a module that approved as "meets standard" or
something like that.

Several advantages:

Just for "-O fun", set up your modules as if they were to be public,
i.e., add a META6.jso for the module collection.
The collection being "/path/to/MyModules" and in MyModules create:

 META6.json # create it and add all your modules in it just like
you were going to publish the whole mess.
 ./lib/
# my modules as moved or duped from "/home/linuxutil/p6lib"
 t/
00-meta-test.t # some basic test to check your META6.json file

Then, in dir "/path/to/MyModules" try:

$ zef install .  # <== that's a DOT/PERIOD, i.e., the current directory

If that works, then you should be able to "use" them from your program.

Since you don't like to listen to advice I give up. The 'so' I was taught

Look at my module Text::Utils and its "commify" sub taken from "The Perl

Todd, the {} is the block defining the subroutine.

The above is the sub's definition.

The above should generate an error because the mandatory args are missing,

The above shows the sub being called with the required two args, and the 5
is the returned value which is probably shown in the REPL since there is no
semicolon after the call and the 5 is not usually seen otherwise.

As usual, you are a bit sloppy in your email text so it's not clear exactly
what you are doing and what the real result is and in what context the

The preferred syntax is:

sub x(--> Hash) {...}

See that in the docs.

Larry Wall once warned that the "return..." syntax may be removed at some

Todd, I don't think that link will help until you understand what actually
you need to contribute a PR.

As I said before, I'll be happy to give you a step-by-step recipe for
creating a PR for the docs after you decide on a clean directory to use for
cloning the doc repository. I think you said you are too busy at the moment.

If you can't find the time now, okay. In any event, you can look at the
Github help section and find out more about PRs. Better yet, go to the Git
home page and check out their documentation (which includes videos).

I have a suggestion that might be a solution, and I tried to get interest
in it in 2015 or 16 when the docs were starting to get a lot of attention:

+ Start something like a Cookbook similar to the printed one published by
O'Reilly for Perl (but watch out for copyright issues such as identical
sections and layout)

Put the cookbook on the current docs site. The docs could stay the way they
are, but, as suggested above, have links into the cookbook for recipes for
real use cases like Todd wants.

With the tooling in place, Todd could start adding his stuff in the
appropriate place, and it would be fair game for editing as necessary.

Also as suggested above, the layout and links to and from the (reference)
docs and the example docs could be automated.

Todd, you need to publish your module to the Raku module ecosystem. Many
people, including myself, want to see an easily-installable module with at
least some basic tests to give strangers confidence that it will not blow
up. Instructions are in the docs, and there are helper modules to get you
started.

I'll send you specific doc references later when I get a chance, but it's
probably better for you to dig around the doc site a bit more on your own.
Hint: in the search box, enter 'module'.

Todd, I was a bit harsh in my last reply, but I do see a huge difference
between a bug report and a PR. In the PR, you have to show exactly what the
wording should be in its entire context, while in the bug report your
suggestions are less in context. To me, that automatically increases the
friction in the  conversation.

Some other points about help via comms other than email that are valuable
to me:

1. when using IRC, it is easy to put chunks of real code into a Github
gist. That way everyone can see it and discuss it by line number or other
reference

2. on the #raku channels, there is a built-in REPL so all can see your code
chunks in action

Finally, I really don't have any more good arguments about your discontent
with the docs, but I leave you with these words about my experience here:

Any help you can contribute to the docs will usually be greatly
appreciated, but you are better off to start in small bits, correcting
typos, improving grammar, etc.
And I agree with you that much of the descriptions are in "IEEE-ese." To
help with that I have added several "cookbook" examples in such areas, as
much to help me as to help others. Given the way I've seen you operate I
think that adding better examples from your "keepers" would be very useful.

Merry Christmas!

-Tom

P.S. One more thing about Perl vs. Raku docs: I believe over the years
there has been much money applied to the Perl infrastructure by commercial
users of Perl, especially in the early days of the Internet. On the other
hand, I believe Raku has had comparatively little commercial support and
has had to rely on those unpaid people who love the language and its
community and who freely donate their time to its improvement. It can only
get better, but maybe not with quite as steep a growth curve as Perl has
had.

Todd, a Pull Request is NOT a bug report. YOU get a Github account,
and YOU fork the Raku docs repository and YOU either make changes on
your Github fork via a browser or, better, clone your fork onto your
favorite local host and make desired changes there. Then, when you are
satisfied, you commit your changes, push them to your Github account,
and then submit a Pull Request which lets a member either approve your
changes or suggest something else.

I wish you could get over your aversion to reading what we have in the
docs. For example, one of the first things you should learned, a long
time ago was about the REPL which you just found about today.

The REPL is mentioned in several places, one place a person new to the
language wold be looking:

  On the home page (raku.org), select the "Download" menu tab on the top row.
  In the right column, in the second pane entitled "Introductory
Material", select the "Raku Guide"
  In the "Table of Contents" in the left column, select "1.4, Running Raku Code"

Granted, it isn't shouted out, but if you had looked around the
various pages you would have found it.

Also, if you would find an IRC client and join channel #raku, you
could ask questions AND try out code online while people are watching.

I realize we all don't search for things or learn them the same way,
but goodness knows the folks who have been helping you on this mailing
list have shown great patience in the face of a lot of criticism
without a lot of constructive help from you in return.

Best regards,

Todd, arguing via email is almost guaranteed to be fruitless. You need
to learn to use Github and make pull requests (PRs)  for the EXACT
changes you think should be made to the docs. With apologies to you,
sometimes it is difficult for a simple man like me to help when your
code is too complex ("golfed") or incomplete to sort out easily in
your email. Your "keepers" could be a PR for changes to the docs.

Note the Perl docs have been refined, by experts, since the late
1980s, while the Raku docs have been expanding, by individuals with
itches to scratch and varying talents, for probably much less than 20
years.

Todd, I took a quick glance at the link you gave and all I saw was
reference to the Brain* language (whose author I believe should be ashamed
of himself for that name--something like "Braincramp" would have been
better).

I have all Andrew's books and read many of his blogs and never noticed any
trend of vulgarity (which, I too, am sensitive to).  I do see evidence of
several Perl and Raku people whose speech can sometimes be quite crude and
blasphemous, but I'm afraid that's the modern world: good manners and
civility have all but disappeared in public places. I will say, though,
that the #Raku IRC channel has much less coarse lingo and much more
kindness than most other places I visit.

I have had several email conversations with Andrew and he seems like a nice
person to me. I sometimes think non-native English speakers pick up bad
speech habits because of the absolutely sewer-mouthed "popular" folks on
Twitter.

One thing I noticed, you are missing a line at the top of your modules that
should read something like "unit module MyModule;", and the
export(:some-key) is okay.

But then, in the calling programs, use them something like this:

use lib ; # MyModule.pm6 is in this dir

I think you will have to file a Rakudo issue.

Laurent, now that you have the algorithm working as desired, can you show

Try eliminating “acme =>” for a starter.

I’ve not yet looked into their use in testing but I shall now!

Note I have plans to update docs on p6 pod but am waiting until I finish
adding a couple of unspecced (not yet implemented) features.  See Rakudo
repo rakudo/docs/rakudo-nqp-notes.md for more info on NYI pod.

The pod classes that currently exist are in Rakudo repo
rakudo/src/core/Pod.pm6. Naming has been a bit inconsistent, but most are
subclasses of Pod::Block, even though the name may not reflect it.

Not all are documented yet.  Your choice d is correct.

Documentation is in several places:

+ the “docs” (docs.perl6.org)

+ roast, mostly in dir S26* (githb.com/perl6/roast)

+ Speculations, mostly S26 (see the bottom-right corner of the home page of
perl6.org)

I agree, Richard, and I started the reorg project but got shot down
because AlexDaniel and others didn’t like the way I separated the page
into the categories. I use an all-caps title in the right (or left if
desired) column.

The plan is for multi-page listing, categories on the first page, and
category breakout on a separate category page for each, but that is a
major effort.

However, in the interim, I sure think my simple solution is better
than what we have.

Thanks for the comment (and support)!

I agree with you for the most part.  But the docs DO have examples,
and any reader who sees the lack of a suitable one should file an
issue or contribute a suitable change.

I got my  start here as a noob p6 user (coming  from years of p5 use)
contributing to the docs. And I, too, found many examples too obtuse
for a noob, and have changed some of them.

As experienced as Todd seems to be in p5, he should be able to improve
the docs one way or the other (but get a good book in the meantime;
Andrew Shitov's "Perl 6 at a Glance" is short and sweet for a first
book, Laurent's "Think Perl 6: How to Think Like a Computer Scientist"
for a deeper look).

Cheers,

Yes it is!

Re: A comparison between P5 docs and p6 docs

[Tom Browder]

Todd, some free advice:

1. DOCUMENTATION

The docs are a volunteer effort. You can help by contributing changes
and submitting issues.

Try to use the docs first instead of using an internet search.  That
will help you submit issues if you don't find what you are looking
for.

You really need to buy one of the fine Perl 6 books that are
available.  See the perl6.org webite and this page:

  https://perl6.org/resources/https://perl6.org/resources/ (look at
the bottom left-hand side)

See this page for book choice help:  https://perl6book.com/

Anyone on the #perl6 IRC (or this mailing list) will be happy to
explain their preferences.

2. DESIGN

The original Perl 6 specifications are here (linked from the
bottom-right of perl6.org):

  https://design.perl6.org/

The specifications are defined in the test suite (also linked from the
bottom-right of per6.org):

  https://github.com/perl6/roast

3. YOUR CODE USE

One of the great features of Perl 6, to me, is the ability to use kebab
case, e.g.,:

  my $some-var = 'a';

When you submit code examples, making them less wordy and "noisy"
would help us help you. Perl 6 code can be be written very sparsely.

Best regards,

-Tom

Re: start up delay?

[Tom Browder]

One thing you can do, depending on your code, is to put most of your
code in subroutines, put them in a module, and 'use' it in your main
script.  The module gets precompiled the first time you execute the
program, and the overall program should be faster after the first go.

The 'zef' program does that to great effect

Best regards,

-Tom

Searching for "rmdir" on the docs site, and selecting the sub rmdir
entry, I see the following:

  To delete non-empty directory, see rmtree in File::Directory::Tree module

with a link to the module's github.com repo:
