NAME
builtin::compat - Provide builtin functions for older perl versions
SYNOPSIS
use builtin::compat qw(
true
false
is_bool
inf
nan
weaken
unweaken
is_weak
blessed
refaddr
reftype
created_as_string
created_as_number
stringify
ceil
floor
trim
indexed
load_module
);
DESCRIPTION
Provides builtin functions for perl versions that do not include the builtin module.
No functions are exported by default.
This module does its best to behave similar to builtin, which creates its exported functions as lexicals. The functions will be created in the currently compiling scope, not the immediate caller of builtin::compat->import
. The functions will also be removed at the end of the compilation scope using namespace::clean.
The builtin functions will be used directly when they are available.
FUNCTIONS
- true
-
See "true" in builtin.
- false
-
See "false" in builtin.
- is_bool
-
See "is_bool" in builtin.
Prior to perl 5.36, it was not possible to track boolean values fully accurately. This function will not be perfectly accurate on earlier perl versions.
- inf
-
See "inf" in builtin.
- nan
-
See "nan" in builtin.
- weaken
-
See "weaken" in builtin.
- unweaken
- is_weak
-
See "is_weak" in builtin.
- blessed
-
See "blessed" in builtin.
- refaddr
-
See "refaddr" in builtin.
- reftype
-
See "reftype" in builtin.
- created_as_string
-
See "created_as_string" in builtin.
Prior to perl 5.36, it was not possible to check if a scalar value was created as a number or as a string fully accurately. This function will not be entirely accurate before then, but should be as accurate as is possible on these perl versions. In particular, a string like "12345" that has been used as a number will cause
create_as_string
to return false andcreated_as_number
to return true. - created_as_number
-
See "created_as_number" in builtin.
Has the same caveats as
created_as_string
. - stringify
- ceil
-
See "ceil" in builtin.
- floor
-
See "floor" in builtin.
- trim
-
See "trim" in builtin.
- indexed
-
See "indexed" in builtin.
- load_module
