METHODS
This package provides the following methods:
call
call(Any @data) (Any)
The call method executes and returns the result of the code.
Since 0.01
- call example 1
-
package main; use Venus::Code; my $code = Venus::Code->new(sub { ($_[0] // 0) + 1 }); my $call = $code->call; # 1
- call example 2
-
package main; use Venus::Code; my $code = Venus::Code->new(sub { ($_[0] // 0) + 1 }); my $call = $code->call(1); # 2
- call example 3
-
package main; use Venus::Code; my $code = Venus::Code->new(sub { ($_[0] // 0) + 1 }); my $call = $code->call(2); # 3
cast
cast(Str $kind) (Object | Undef)
The cast method converts "value" objects between different "value" object types, based on the name of the type provided. This method will return undef
if the invocant is not a Venus::Kind::Value.
Since 0.08
- cast example 1
-
package main; use Venus::Code; my $code = Venus::Code->new(sub{[@_]}); my $cast = $code->cast('array'); # bless({ value => [sub { ... }] }, "Venus::Array")
- cast example 2
-
package main; use Venus::Code; my $code = Venus::Code->new; my $cast = $code->cast('boolean'); # bless({ value => 1 }, "Venus::Boolean")
- cast example 3
-
package main; use Venus::Code; my $code = Venus::Code->new(sub{[@_]}); my $cast = $code->cast('code'); # bless({ value => sub { ... } }, "Venus::Code")
- cast example 4
-
package main; use Venus::Code; my $code = Venus::Code->new; my $cast = $code->cast('float'); # bless({ value => "1.0" }, "Venus::Float")
- cast example 5
-
package main; use Venus::Code; my $code = Venus::Code->new(sub{[@_]}); my $cast = $code->cast('hash'); # bless({ value => { "0" => sub { ... } } }, "Venus::Hash")
- cast example 6

- cast example 7
-
package main; use Venus::Code; my $code = Venus::Code->new; my $cast = $code->cast('regexp'); # bless({ value => qr/.../, }, "Venus::Regexp")
- cast example 8

compose
compose(CodeRef $code, Any @data) (CodeRef)
The compose method creates a code reference which executes the first argument (another code reference) using the result from executing the code as it's argument, and returns a code reference which executes the created code reference passing it the remaining arguments when executed.

package main; use Venus::Code; my $code = Venus::Code->new(sub { [@_] }); my $compose = $code->compose($code, 1, 2, 3); # sub { ... } # $compose->(4, 5, 6); # [[1,2,3,4,5,6]]
conjoin
conjoin(CodeRef $code) (CodeRef)
The conjoin method creates a code reference which execute the code and the argument in a logical AND operation having the code as the lvalue and the argument as the rvalue.
Since 0.01
- conjoin example 1
-
package main; use Venus::Code; my $code = Venus::Code->new(sub { $_[0] % 2 }); my $conjoin = $code->conjoin(sub { 1 }); # sub { ... } # $conjoin->(0); # 0 # $conjoin->(1); # 1 # $conjoin->(2); # 0 # $conjoin->(3); # 1 # $conjoin->(4); # 0
