Hello Rakuns,
How do i access the declarator block of my object method?
I'm trying to do this, but it's not working:
class A {
#|( This is just a test with 3 parameters:
* p1 - parameter 1
* p2 - parameter 1
* p2 - parameter 1
)
method test($p1, $p2, $p3
Jo,
For what its worth, the search page on http://raku.finanalyst.org now
takes you to ^methods
Previously, a search on '^methods' found the reference, but hide the
location, so the link could not be clicked. That is fixed now.
Regards,
Richard

So, would you say you now understand that `.value` is a
method call on an "invocant" that is either explicitly written
to the left of the `.` or is implicitly whatever the current topic
is where the `.value` appears?
No idea since you hinted to a newbie like myself.

There are four different types of a function. (both method and sub)
- `multi`
- `proto`
- `only`
- `anon`
A `proto` function is mainly just to declare there will be multiple

`multi` is short for "multiple", meaning more than one.

you to call methods without parenthesis like this:
class Foo
{
method print($x, $y)
{
say "bar: {$x}, {$y}"
}
}
my $a = Foo.new;
$a.p
Easy for you to say... (haha)
Nice! Many thanks.

Hi Mark,
get_value won't give you what you expect. It's use is narrowly limited to trait
'is handles' and method .perl. Besides, are you sure all of your attributes
will be considered as belonging to XML? I mean, won't there be need for utility
attributes serving exclusively internal needs
Perl6 Community,
How do I properly wrap an attribute’s ^get_value method in TWEAK? If a
condition exists, I’d like to wrap all (:local) attributes so that they can do
some extra work.
The module that I’m working on has classes/attributes for hundreds of fields in
dozens of different, big XML
You got the order of operations wrong.
Method calls happen before prefix operators
These are identical
+@a.so
+(@a.so)
@a.so.Numeric
@a.Bool.Numeric
+?@a
As are these
+«@a».so
+«(@a».so)
@a».so».Numeric
@a».Bool».Numeric
+«?«@a
Postfix operators also
Hi Richard,
I don't think it's a bug. In:
put +@a.so;
the @a array is coerced into a Boolean value (True) by the so method, and
the resulting Boolean value is then coerced into an integer by the +
operator.
Cheers, Laurent.

A snippet:
my @a = 1..10;
put +@a.so; # output 1
put so(+@a); # output True
put (+@a).so; # output True
This caught me because I used +@s.so when I tried to do something like:
# in a class with 'has Bool $.pass;'
return unless ( $!pass = +@a.so );

Maybe a note in the docs would be useful to others.

The reason `dir('a', test => { .IO.d })` doesn't work like you expect
is that it is passed strings.

.
c
b
..
("a/.".IO "a/c".IO "a/b".IO "a/..".IO)
So `.IO.d` is looking to see if the CWD directory had a directory of
that name, not the `a`

Here's output of 'a/b'.IO.d from the REPL:

True

The dir method gives you entries in the directory you pass. If you don't
pass a test it'll use the default test which is none(".", ".."), i.e.
"anything except . and ..".
I'm not sure why using { .IO.d } as the test would not give you b,
though. Can you check
Hello,
I think that I don't understand how the 'test' argument of 'dir' works.
I have a directory 'a', which contains a subdirectory 'b' and a file 'c'; I
want to select only the subdirectories of 'a'.
Using the REPL I tried to ask the content of the directory 'a':
> my @dirs = dir('a')
