probably worth a bug report ?

[Marc Chantreux]

hello rakoons,

I got this error message

Too few positionals passed; expected 1 argument but got 0
  in sub xxx at - line 1
  in block  at - line 2

Welcome to 퐑퐚퐤퐮퐝퐨™ v2021.09.
Implementing the 퐑퐚퐤퐮™ programming language v6.d.
Built on MoarVM version 2021.09.

by running this:

<<\-. raku; raku -v
sub xxx ( Pair $test ) { $test.raku.say }
xxx key => 'value';

and i think it's worth a bug: i don't know if

xxx key => 'value'

should parse but at least it deserve a less
confusing message, don't you think ?

regards
marc

That was notified a long time ago. IIRC, the PR was merged, but has not
been deployed yet.

That's not really needed, it's just a bit of goldplating.

You need to click on the log. But you can safely ignore that.

Raku name change

[Richard Hainsworth]

Just noticed when creating new module on GitHub, the dropdown for the 
.gitignore template has an entry for 'perl6' but not for raku.

Re: Should I start learning Perl?

[Parrot Raiser]

A great analysis of, and answer to, the question. Worthy of being
enshrined in a blog posting.

Re: continuous testing

[Richard Hainsworth]

Thanks. That is very useful. One interesting question.

I notice from this setup that you chart the COMMITS, and the raku 
program uses 'say' to output the results.


But how do you access these charted results?

Regards,

Richard

You can also copy a configuration from another project and adapt

some module dependencies and runs the tests:

Re: Should I start learning Perl?

[Richard Hainsworth]

Mr. Turritopsis Dohrnii Teo En Ming,

Happy New Year from Wales.

You asked:

May I know if Perl is still in vogue?
Should I start learning Perl?

There is Perl and what used to be called Perl6, which is now called 
Raku. This is an email list for Raku, aka Perl 6.


Lets start with 'vogue-ness'.

When I was a student, FORTRAN was the main language for science, and 
COBOL was for finance. When I first set up an intranet for KPMG in their 
Moscow office, Perl 5 had just appeared and it was THE internet 
language. Since then many languages have come into fashion, and Python, 
JAVA, and Go seem to me to be widespread, whilst C remains incredibly 
important. You can find listings of popular languages on the internet.


However, consider that once a piece of software has been written in a 
language, transferring it 100% to another language is very difficult. 
Transferring about 95% is easy, but it is the rare cases that are 
difficult to get right. So companies with huge investments in software 
systems written in COBOL, Fortran, and Perl do not want to change the 
language, and they look for programmers who can maintain these software 
systems. Even though most programmers hate COBOL as a language (it is 
now old, but in its day was ground-breaking), COBOL programmers get high 
salaries from big companies with large software investments.


The same is even more true of Perl. Perl continues to be a good 
language, with VERY many modules and new ones being written, with VERY 
many companies relying on existing software systems based on Perl.


So does 'in vogue' mean what is fashionable today, but discarded 
tomorrow, or does it mean something for which there is a massive and 
continuing demand? Note that here I am trying to distinguish between 
volatile 'fashion' and what is in demand, which is an aspect of being 
'in vogue'.


It might easily be true that programmers are paid more if they have 
skills in languages with large installed bases, but which are out of 
fashion! The reason is that languages 'in fashion' attract many young 
people, who are taught these languages in schools and colleges. So the 
population of junior programmers with 'in fashion' skills is large. 
Programmers with older language skills are rarer, so they get paid more.


So if you are looking for a language to serve you in a career, then do 
not look at 'fashion', but look at the installed base. In which case 
Perl is a very good choice.


More important for a good programmer, though, is to learn the "Way" or 
"Art" of programming because various techniques for writing good 
software are applied in any different languages. Essential to good 
programming is testing, and particularly unit testing. I only started to 
use unit tests as part of the way I develop software quite late in my 
career. It is so easy to dismiss it as extra admin, rather than an 
essential way of thinking about the results generated by software. Also, 
things like program structure, naming variables and code elements in a 
self-documenting manner, differentiating between inheritance and code 
re-use, and so on are vital for good progamming.


Raku (previously known as Perl 6) is an excellent choice of language to 
learn because it has been designed to make good programming techniques 
easy. Once you have mastered important software techniques in Raku, you 
can then employ them in other settings.


At one time, I had to write in Java (for Android apps) and C (embedded 
systems), but for all my own tasks I used Raku. At the time Raku was 
very slow to compile (that is getting much better), but the ease with 
which I could write a small script to do a complex thing in a way that 
is easy to understand and debug is unmatched (I think) by any other 
language.


Raku is still at the forefront of language design, with its ability to 
handle Unicode (eg., you can name your variables in simplified or 
traditional Chinese script), grammars, concurrent programming, and 
several other areas. Why is Raku not more widespread? Probably because 
it does not have a big company sponsoring its development, and 
advertising it.


So short responses to your questions:

Is Perl 'in vogue' in the meaning of is it fashionable? Is that a good 
question to be asking? The answer is 'Perl is not as fashionable as it 
once was'. But are you asking because you only want to follow fashion, 
or are you asking to see how best to develop yourself in your career, or 
as a programmer. Is Perl in vogue because it is widely used, then yes 
Perl is in vogue.


Is Raku fashionable? If you look at the quality of the people in the 
Raku community, and their experience with other languages, and when you 
consider the types of things that interest computer scientists and being 
implemented in Raku, then 'yes, Raku is fashionable'. But if by 
fashionable, you mean what is being hyped by influencers, or companies 
with money trying to get you locked into their products, then 'no, Raku 
is not fashionable'.

[Elizabeth Mattijsen]

If you're looking for Perl, you're probably on the wrong mailing list: I 
suggest you try "perl.beginners".

Well, we can very well ship a Docker image that includes Raku by default...

Good day from Singapore,

I am thinking of learning Perl. May I know if Perl is still in vogue?
