Question
Are there built-in methods that will take a list and cycle through it indefinitely, producing, say, the lazy list
...ANSWER
Answered 2020-Oct-17 at 04:03When it can be written this short, why add a feature just for that. Especially since it is probably a rare event that you would need such a thing.

QUESTION
According to p6doc 5to6-perlfunc
:
FILE
Replaced by
$?FILE
which is slightly different from__FILE__
in that it is always an absolute path, rather than a relative one in the Perl 5 case.
and according to p6doc CallFrame
:
With no arguments the
callframe
will give you frame information for the line callingcallframe
. The file and line annotations will be identical to those in$?FILE
and$?LINE
.
But when I tested this, the file
attribute gives a relative path name:
./p.p6:
...ANSWER
Answered 2019-Apr-17 at 20:54Have you looked at the absolute method from IO::Path?
say "func: Calling package's file name: ", $frame.file.IO.absolute;
QUESTION
You can use the adverb :delete
in Perl 6 to delete an array element if you know its index:
ANSWER
Answered 2018-Jun-02 at 09:01Depends on what you call delete
. Internally, on arrays, doing a DELETE-POS
binds the element in the array to nqp::null
, which will discard any container living at that position. At the HLL level, this is represented by the type of the array:

QUESTION
Is there an alternate way in perl6 to get file attribute details like size, access_time, modified_time.. etc. without having to invoke native call?
As per the doc it is "unlikely to be implemented as a built in as its POSIX specific".
What workaround options are available excluding the system call to stat?
Any ideas or pointers are much appreciated.
Thanks.

QUESTION
In Perl 5, I can open a filehandle on string like this:
...ANSWER
Answered 2018-Jul-18 at 18:03EDIT: See this question for how to do what @raiph says about opening a filehandle to a string. Also, read @raiph's comments.
This is how to open a filehandle to a file from a string, not how to open a filehandle to a string without a file being involved. Thanks to @raiph for clarifying the OP's meaning.
The documentation has a section called Input/Output that describes this process.
One way to read the contents of a file is to open the file via the open function with the :r (read) file mode option and slurp in the contents:
QUESTION
I have a form in which once filled in it sends an email to the user and should give a price based on what option they selected within the dropdown.
I have an if statement to see what option has been selected within the drop down. Within the if statement it should set the $Price variable to $Price = '£300';
The $Price variable is then added into the $body variable to be sent. The value of the $Price variable doesn't show within the email but when I take the $Price = '£300'; out of the if statement it is visible within the email.
I have made sure that the problem isn't the options dropdown selection as it works when the variable is placed within the echo 'Sent' , $Price;
PHP:

Answered 2017-Jan-22 at 15:20You are checking $Property_Value
before setting any value to the variable
You have to first set the value, then check for any condition on that variable like:
