NAME
File::Path::Tiny - recursive versions of mkdir() and rmdir() without as much overhead as
File::Path
VERSION
This document describes File::Path::Tiny version 0.7
SYNOPSIS
use File::Path::Tiny;
if(!File::Path::Tiny::mk($path)) {
die "Could not make path '$path': $!";
}
if(!File::Path::Tiny::rm($path)) {
die "Could not remove path '$path': $!";
}
DESCRIPTION
The goal here is simply to provide recursive versions of mkdir() and rmdir() with as
little code and overhead as possible.
This module is in no way meant to derogate File::Path and is in no way an endorsement to
go out and replace all use of File::Path with File::Path::Tiny.
File::Path is very good at what it does but there's simply a lot happening that we can do
without much of the time.
Here are some things File::Path has/does that this module attempts to do without:
· multiple interfaces
Backwards compatibility brings in a lot of code and logic that we don't need from here
on out.
· chdir()s
It does a ton of chdir()s which could leave you somewhere you're not planning on being
and requires much more overhead to do.
· can croak not allowing you to detect and handle failure
Just let me handle errors how I want. Don't make my entire app die or have to wrap it
in an eval
· A well intentioned output system
Just let me do the output how I want. (Nothing, As HTML, print to a filehandle,
etc...)
· A well intentioned and experimental (IE subject to change) error handling system.
Just keep it simple and detect failure via a boolean check and do what I want with the
error. See "How can I make/remove multiple paths?"
· According to its POD, removing a tree is apparently not safe unless you tell it to be
with the XsafeX or 'keep_root' attributes.
Seems like that should just happen, I don't want to worry about accidentally removing
/ when I pass it /tmp
INTERFACE
Nothing in exported or exportable, that helps keep it '::Tiny'.
File::Path::Tiny::mk()
Takes a single path (like mkdir()) to recursively create and, optionally, a mask (like
mkdir()) for all subsequent mkdir() calls.
Mask defaults to 0700 (also like mkdir())
Returns false if it could not be made, true otherwise (returns X2X if it is -d already)
It is recursive in the sense that given Xfoo/bar/bazX as the path to create all 3 will be
created if necessary.
File::Path::Tiny::rm()
Takes a single path (like rmdir()) to recursively empty and remove.
Returns false if it could not be emptied or removed, true otherwise. (returns X2X if it is
!-d already)
It is recursive in the sense that given X/foo/bar/bazX as the path to remove it will
recursively empty XbazX and then remove it from /foo/bar.
Its parents, /, /foo, and /foo/bar are *not* touched.
File::Path::Tiny::empty_dir()
Takes a single path to recursively empty but not remove.
Returns false when there is a problem.
File::Path::Tiny::mk_parent()
Like mk() but recursively creates the parent. e.g. given Xfoo/bar/baz.txtX creates
foo/bar.
DIAGNOSTICS
Throws no warnings or errors of its own
If the functions ever return false, $! will have been set either explicitly or by the
mkdir(), rmdir(), unlink(), or opendir() that ultimately returned false.
MISC
How can I make/remove multiple paths?
For simplicity sake && ::Tiny status this module must be very very very simple.
That said it is also very simple to do multiple paths:
for my $path (@paths) {
File::Path::Tiny::::mk($path) or _my_handle_failed_mk($path, $!);
}
for my $path (@paths) {
File::Path::Tiny::::rm($path) or _my_handle_failed_rm($path, $!);
}
That also lets you keep going or short circuit it or handle errors however you like:
PATH:
for my $path qw(foo/bar bar/rat) {
if (!File::Path::Tiny::mk($path)) {
print "problem unlinking '$path': $!\n";
last PATH;
}
else {
print "No error encountered with '$path'\n"
}
}
About the '::Tiny' status
See Acme::Tiny for information on the ::Tiny suffix.
#3 is almost there (< 1/5th +/-), a bit more trimming and I think we'll have it!
#8 is N/A since part of the "sub set" is to do single paths like their non-recursive core counterparts and there are so many ways to invoke it with different consequences
[ -- RSS Memory -- ]
Baseline perl 1168
File::Path 1808 (+640)
File::Path::Tiny 1288 (+120)
Even though "time" isn't really a ::Tiny factor, it does improve loading a bit:
[ -- time -- ]
Baseline perl
real 0m0.007s
user 0m0.002s
sys 0m0.004s
File::Path
real 0m0.017s
user 0m0.011s
sys 0m0.005s
File::Path::Tiny
real 0m0.007s
user 0m0.003s
sys 0m0.004s
As time allows and more tests are added I'll try to include more comprehensive benchmark
results.
How do I make sure the path is safe to create or remove?
Of course the answer depends on what you mean by "safe".
This module makes no assumptions on interpreting the "safeness" of a path, just like
mkdir() and rmdir().
Also like mkdir() and rmdir() typically you'll find that filesystem permissions are a
pretty reliable tool (of course if the code will be run as root you would want to setuid
first...)
You might use Cwd::abs_path() to sanitize a path before sending it to be made or removed.
Even after that it might not be "safe" so you'll need to discern what your particular
definition of "safe" is and take appropriate action.
DEPENDENCIES
File::Spec of course but its only loaded if needed
