String::Elide::Parts - Elide a string with multiple parts of different priorities
This document describes version 0.07 of String::Elide::Parts (from Perl distribution String-Elide-Parts), released on 2017-01-29.
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):
$text = "<elspan prio=2>Downloading</elspan> <elspan prio=3 truncate=middle>http://www.example.com/somefile</elspan> 320.0k/5.5M"; # 0----5---10---15---20---25---30---35---40---45---50---55---60 elide($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
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.
Elide a string if length exceeds $len.
String can be marked with "<elspan prio=N truncate=T marker=M>...</elspan>" 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.

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.
