Hi Peter,
No doubt it is operating as designed.
It would be a lot more friendly if "Str:U" was
changed to "Str:D". Oh please! Oh Please!
Sorry, I don't really understand what you mean. "Str:U" means
an undefined string - that's what you're calling .starts-with() on.
"Str:D" means a defined string - that's what .starts-with() wants to
operate on. What do you mean "change Str:U to Str:D" - the error
message says "you invoked it on an undefined string, it wants to be
invoked on a defined string", what do you want to change?
Now, if you meant "change Str:U to 'an undefined string'", mmmm, what
I was trying to explain is that the error message is generic, it covers
any wrong calls of functions on any types... it does not really try to
get into what the types are (it cannot, in the general case for any
other type).
G'luck,
Peter
Hi Peter,
What a second.
https://docs.raku.org/routine/starts-with
multi method starts-with(Str:D: Str(Cool) $needle, :i(:$ignorecase),
:m(:$ignoremark) --> Bool:D)
https://docs.raku.org/routine/contains
method contains(Cool:D: |c)
I had incorrectly presumed that since neither of
these two complained about `Str:D` not being defined
that it was specified as `Str:U`
So my beef is when you feed these guys an undefined
variable, that they needs to tell you it requires
a "defined" variable. Not a bunch of useless rubbish.
For example (useless rubbish):
Cannot resolve caller starts-with(Str:U: Str:D);
none of these signatures match
(Cool:D: Cool:D $needle, :i(:$ignorecase)!,
:m(:$ignoremark), *%_ --> Bool)
(Cool:D: Cool:D $needle, :m(:$ignoremark)!, *%_
--> Bool)
(Cool:D: Cool:D $needle, *%_ --> Bool)
(Str:D: Str:D $needle, :i(:$ignorecase)!,
:m(:$ignoremark), *%_ --> Bool)
(Str:D: Str:D $needle, :m(:$ignoremark)!, *%_ --> Bool)
(Str:D: Str:D $needle, *%_ --> Bool)
in block <unit> ...
And I know, I don't get a vote on the matter.
