SYNOPSIS
use String::Elide::Parts qw(elide);
Eliding string with no parts:
my $text = "this is your brain";
# 0----5---10---15---20
elide($text, 16); # -> "this is your ..."
elide($text, 16, {truncate=>"left"}); # -> "...is your brain"
elide($text, 16, {truncate=>"middle"}); # -> "this is... brain"
elide($text, 16, {truncate=>"ends"}); # -> "... is your b..."
elide($text, 16, {marker=>"--"}); # -> "this is your b--"
Eliding string with multiple parts marked with markup. We want to elide
URL first (prio=3), then the Downloading text (prio=2), then the speed
(prio=1, default):
$text = "Downloading http://www.example.com/somefile 320.0k/5.5M";
# 0----5---10---15---20---25---30---35---40---45---50---55---60
elide($text, 56); # -> "Downloading http://www.example.com/somefile 320.0k/5.5M"
elide($text, 55); # -> "Downloading http://www.example.com/somefile 320.0k/5.5M"
elide($text, 50); # -> "Downloading http://www.e..com/somefile 320.0k/5.5M"
elide($text, 45); # -> "Downloading http://ww..m/somefile 320.0k/5.5M"
elide($text, 40); # -> "Downloading http://..omefile 320.0k/5.5M"
elide($text, 35); # -> "Downloading http..efile 320.0k/5.5M"
elide($text, 30); # -> "Downloading ht..le 320.0k/5.5M"
elide($text, 25); # -> "Downloading . 320.0k/5.5M"
elide($text, 24); # -> "Downloading 320.0k/5.5M"
elide($text, 23); # -> "Download.. 320.0k/5.5M"
elide($text, 20); # -> "Downl.. 320.0k/5.5M"
elide($text, 15); # -> ".. 320.0k/5.5M"
elide($text, 13); # -> " 320.0k/5.5M"
elide($text, 10); # -> " 320.0k/.."
elide($text, 5); # -> " 32.."
# 0----5---10---15---20---25---30---35---40---45---50---55---60
DESCRIPTION
String::Elide::Parts is similar to other string eliding modules, with
one main difference: it accepts string marked with parts of different
priorities. The goal is to retain more important information as much as
possible when length is reduced.
FUNCTIONS
elide($str, $len[, \%opts]) => str
Elide a string if length exceeds $len.
String can be marked with ... so there can be multiple parts with different
priorities and truncate direction. The default priority is 1. You can
mark less important strings with higher priority to let it be elided
first. The markup will be removed from the string before eliding.
Known options:
* marker => str (default: '..')
* truncate => 'left'|'middle'|'middle'|'ends' (default: 'right')
* default_prio => int (default: 1)
SEE ALSO
Similar elide modules
Text::Elide is simple, does not have many options, and elides at word
boundaries.
String::Truncate has similar interface like String::Elide::Parts and
has some options.
String::Elide::Lines is based on this module but works on a line-basis.
