NAME
path-utils - low-level path introspection utility functions
SYNOPSIS
use path-utils; # export all subs
use path-utils <path-exists>; # only export sub path-exists
say path-exists($filename); 0 or 1
DESCRIPTION
path-utils provides a number of low-level path introspection utility functions for those cases where you're interested in performance, rather than functionality.
All subroutines take a (native) string as the only argument.
Note that these functions only return native int
and native num
values, which can be used in conditions without any problems, just don't expect them to be upgraded to Bool
values.
Also note that all functions (except path-exists
) expect the path to exist. An exception will be thrown if the path does not exist. The reason for this is that in situations where you are already sure a path exists, there is no point checking for its existence again if you e.g. would like to know its size.
SELECTIVE IMPORTING
use path-utils <path-exists>; # only export sub path-exists
By default all utility functions are exported. But you can limit this to the functions you actually need by specifying the names in the use
statement.
To prevent name collisions and/or import any subroutine with a more memorable name, one can use the "original-name:known-as" syntax. A semi-colon in a specified string indicates the name by which the subroutine is known in this distribution, followed by the name with which it will be known in the lexical context in which the use
command is executed.
use path-utils <path-exists:alive>; # export "path-exists" as "alive"
say alive "/etc/passwd"; # 1 if on Unixy, 0 on Windows
