Text::VisualWidth - Perl extension for trimming text by the number of the columns of terminals and mobile phones.
use Text::VisualWidth::EUC_JP; my $length = Text::VisualWidth::EUC_JP::width($str); my $str = Text::VisualWidth::EUC_JP::trim($str, 20); use Text::VisualWidth::UTF8; my $length = Text::VisualWidth::UTF8::width($str); my $str = Text::VisualWidth::UTF8::trim($str, 20);
This module provides functions to treat half-width and full-width characters and display correct size of text in one line on terminals and mobile phones. You can know the visual width of any text and truncate text by the visual width. Now this module support EUC-JP and UTF-8 and tested only with Japanese.
