Arch::TempFiles(3pm) User Contributed Perl Documentation Arch::TempFiles(3pm)NAME
Arch::TempFiles - help to manage temporary files/dirs
SYNOPSIS
use Arch::TempFiles qw(temp_file_name temp_file temp_dir);
# all will be removed automatically on the script completion
my $file_name1 = temp_file();
my $file_name2 = temp_file_name("status");
my $dir_name = temp_dir("arch-tree");
use Arch::TempFiles;
my $tmp = new Arch::TempFiles;
$tmp->root($tmp->dir);
my $file_name = $tmp->name;
open OUT, ">$file_name";
close OUT;
DESCRIPTION
This module deals with temporary file names. It is similar to File::Temp, but simplier and more focused. Also, File::Temp is relatively new
and was not shipped with older perl versions.
Both function interface and object oriented interface are supported.
FUNCTIONS /METHODS
The following functions are available:
temp_root, temp_name, temp_file_name, temp_dir_name, temp_file, temp_dir.
The corresponding class methods are available too:
root, name, file_name, dir_name, file, dir.
temp_root [dir]
$tmp->root [dir]
Change or return the root of the temporary files and dirs. The default is either $ENV{TMP_DIR} or "/tmp".
temp_name [label]
$tmp->name [label]
Return the unused temporary file name. The default file name is "/tmp/,,arch-XXXXXX" where XXXXXX is a random number. To change this
name use "temp_root" and/or provide label that replaces "arch".
Please note, that the operation of acquiring the file name using this function/method and actual creating of this file is not atomic.
So you may need to call this method again if the creation is failed, for example if some other process created the same file in the
middle.
temp_file_name [label]
$tmp->file_name [label]
Like "temp_name", but stores the name in the file list that will be removed on the end (on object destruction).
temp_dir_name [label]
$tmp->dir_name [label]
Like "temp_name", but stores the name in the dir list that will be removed on the end (on object destruction).
temp_file [label]
$tmp->file [label]
Like "temp_file_name", but also creates the file.
temp_dir [label]
$tmp->dir [label]
Like "temp_dir_name", but also creates the dir.

Awaiting for your reports.
