SYNOPSIS
use NetSDS::Util::String qw();
# Read from standard input
my $string = <STDIN>;
# Encode string to internal structure
$string = string_encode($tring);
DESCRIPTION
"NetSDS::Util::String" module contains functions may be used to quickly solve string processing tasks like parsing, recoding, formatting.As in other NetSDS modules standard encoding is UTF-8.
EXPORTED FUNCTIONS
- str_encode($str[, $encoding]) - encode string to internal UTF-8
-
By default this function treat first argument as byte string in UTF-8
and return it's internal Unicode representation.
In case of external character set isn't UTF-8 it should be added as second argument of function.
# Convert UTF-8 byte string to internal Unicode representation $uni_string = str_encode($byte_string); # Convert KOI8-U byte string to internal $uni_string = str_encode($koi8_string, 'KOI8-U');After "str_encode()" it's possible to process this string correctly including regular expressions. All characters will be understood as UTF-8 symbols instead of byte sequences.
- str_decode($str[, $encoding]) - decode internal UTF-8 to byte string
-
By default this function treat first argument as string in internal UTF-8
and return it in byte string (external) representation.
In case of external character set isn't UTF-8 it should be added as second argument of function.
# Get UTF-8 byte string from internal Unicode representation $byte_string = str_decode($uni_string); # Convert to KOI8-U byte string from internal Unicode $koi8_string = str_encode($uni_string, 'KOI8-U');It's recommended to use "str_encode()" when preparing data for communication with external systems (especially networking).
- str_recode($str, $FROM_ENC[, $TO_ENC]) - recode string
- Translate string between different encodings. If target encoding is not set UTF-8 used as default one.
- str_trim($str) - remove leading/trailing space characters
-
$orig_str = " string with spaces "; $new_str = str_trim($orig_str); # Output: "string with spaces" print $new_str; - str_trim_left($str) - removes leading whitespaces
- This function is similar to "str_trim()" except of it removes only leading space characters and leave trailing ones.
- str_trim_right($str) - removes trailing whitespaces
- This function is similar to "str_trim()" except of it removes only trailing space characters and leave leading ones.
- str_clean($str) - clean string from extra spaces
- Function is similar to "str_trim()" but also changes all spacing chains inside string to single spaces.
- str_camelize($strin)
-
If pass undef - return undef.
If pass '' - return ''.
Examples:
# returns 'getValue' str_camelize( 'get_value' ) # returns 'addUserAction' str_camelize( 'ADD_User_actION' ) - str_decamelize(...)
-
If pass undef - return undef.
If pass '' - return ''.
Examples:
# returns 'get_value' str_decamelize( 'getValue' )
