NAME
RoPkg::Utils - general pourpose class.
VERSION
0.4.6
DESCRIPTION
RoPkg::Utils is a collection of methods used by all other modules in RoPkg.
SYNOPSIS
#!/usr/bin/perl
use strict;
use warnings;
use RoPkg::Utils;
sub main {
my $u = new RoPkg::Utils;
print $u->ZeroPad(1),$/,
$u->ZeroPad(1, 3),$/,
RoPkg::Utils::ZeroPad(1, 3),$/;
eval {
$u->CreateFile('/tmp.xyz', 'test message');
};
if (my $e = Exception::Class->caught('File::Create')) {
print $e->message,$/;
exit(1);
}
return 0;
}
main();
When we run this, we have:
01
001
001
Could not create /tmp.xyz
Permission denied
SUBROUTINES/METHODS
new()
CheckParam($object, @param_list)
ZeroPad($number, $pad_length)
GetMonthNo($month_name, $padding)
ElemInList($element_name, @element_list)
GetHumanDate($timestamp)
SecToTime($seconds)
AddSlash($text)
DelSlash($text)
CreateFile($file_path, $content)
ReadFile($file_path)
CleanURI($uri)
CleanPath($path)
GetMD5($path)
All methods raise the following exceptions:
*) Param::Missing when a required parameter is not found in the parameters list.
*) Param::Wrong when a parameter does not comply with the rules. For example when a method
expects a number and finds a string.
Besides these exceptions, each method might raise some specific exceptions (see
CreateFile). new() is provided for OO. It doesn't do anything special, besides the
blessing.
Methods details
RoPkg::Utils exports all the methods from the above list. Of course, you can select which
ones you want to import.
Example:
use RoPkg::Utils qw(ZeroPad);
sub main {
print ZeroPad(1, 3),$/;
}
main();
CheckParam
Check if the parameters from the list are defined inside the object. If the parameters
are not defined Param::Missing exception is raised.
Example
package RoPkg::TesterPkg;
sub new {
my ($class, %opt) = @_;
my $self;
$self = bless { %opt }, $class;
$self->_test_options_1();
$self->_test_options_2();
return $self;
}
sub _test_options_1 {
my ($self) = @_;
RoPkg::Utils::CheckParam($self, qw(dbo dbo_method));
return 1;
}
sub _test_options_2 {
my ($self) = @_;
my $ru;
$ru = new RoPkg::Utils;
$ru->CheckParam($self, qw(dbo dbo_method));
return 1;
}
1;
ZeroPad
This method is usefull when you need to pad with zeroes some numbers. For the moment
positive and negative numbers are suported (only integer ones). This method takes 2
parameters $number and $pad_length. The $number is the number who is going to be padded,
$pad_length is the maximum length. Zeroes are added until $pad_length is reached. If
$pad_length is not defined, length($number)+1 is used. If $pad_length is less than number
length, no padding is done. Ex:
ZeroPad(1, 2) => 01
ZeroPad(12, 5) => 00012
ZeroPad(-3, 4) => -003
ZeroPad(10, 2) => 10
GetMonthNo
Used to find a month numeric index (1..12). For the moment full month names and short
month names (first 3 letters) are supported. 2 parameters may be passed to this method:
$month_name and $padding. $month_name must be January .. December or Jan .. Dec . If the
month_name is not found, Param::Unknown exception is raised. $padding is used to pad the
numeric index of the month. When padding is not defined, no padding is made. Ex:
GetMonthNo('Jan') => 1
GetMonthNo('Jan', 2) => 01
GetMonthNo('January') => 1
GetMonthNo('January', 2) => 01
ElemInList
Takes two parameters. A element value and a list of elements. The methods, search the
element value within the list. Returns 1 if the element was found, 0 otherwise. Ex:
ElemInList(1, qw(1 2 3 4)) => 1
ElemInList(1, qw(2 3 4)) => 0
GetHumanDate
Converts the timestamp to YYYY/MM/DD HH:MM format. Ex:
GetHumanDate(12345678) => '1970/05/23 23:21'
SecToTime
Converts the seconds to <x days> HH:MM:SS format. Ex:
SecToTime(3) => 00:00:03
SecToTime(61) => 00:01:01
AddSlash
Adds a slash at the end of the string, if the slash is not present. Othewise, leaves the
string untouched. Ex:
AddSlash('mydirectory') => 'mydirectory/'
AddSlash('/tmp/') => '/tmp/';
DelSlash
Removes the slash from the end of the string. If the string has multiple slashes, only the
last one is removed. If the string doesn't have any slashes at the end, no modification is
made. Ex:
DelSlash('/tmp/') => '/tmp'
DelSlash('/tmp//') => '/tmp/'
CreateFile
Creates a file (with the filename specified), and optionally set the content of the file
to the one specified by $content variable. If $content is not defined, the file is just
created. If the file can't be created File::Create exception is raised. Returns 1 upon
success.
ReadFile
Reads the content of the specified file into a variable. If the file can't be opened a
File::Open exception is raised. On success returns the file content or !defined if the
file is empty.
CleanURI($uri)
Cleans the $uri from the excedent / -es .
Example:
my $uri = 'http://www.packages.ro//test///uri';
$uri = CleanURI($uri);
print $uri,$RS;
the result is:
http://www.packages.ro/test/uri
CleanURI recognise only ftp,http and rsync uri's . Any other uri is ignored
CleanPath($path)
Cleans the $path from the excedent / -es .
Example:
my $path = '/var/ftp/mirrors///pub//debian.org//';
$path = CleanPath($path);
print $path, $RS;
the result is:
/var/ftp/mirrors/pub/debian.org/
GetMD5($path)
Returns the base64 md5 sum for the specified file.
