Top Forums Shell Programming and Scripting Real-time scenarios where VARIABLE SUBSTITUTION/EXPANSION is useful Post 302946368 by Chubler_XL on Monday 8th of June 2015 06:14:50 PM

I tend to use ${variable%pattern} most frequently to remove extensions from filenames. Second most common usage is probably splitting up strings (date or time strings for example):

Code:
year=${date%%[/ -]*}
day=${date##*[/ -]}
month=${date#*[/ -]}
month=${month%[/ -]*}

HTML::FormHandler::Field::Date(3pm)			User Contributed Perl Documentation		       HTML::FormHandler::Field::Date(3pm)

NAME
HTML::FormHandler::Field::Date - a date field with formats VERSION
version 0.40013 SUMMARY
This field may be used with the jQuery Datepicker plugin. You can specify the format for the date using jQuery formatDate strings or DateTime strftime formats. (Default format is format => '%Y-%m-%d'.) d - "%e" - day of month (no leading zero) dd - "%d" - day of month (two digit) o - "%{day_of_year}" - day of the year (no leading zeros) oo - "%j" - day of the year (three digit) D - "%a" - day name short DD - "%A" - day name long m - "%{day_of_month" - month of year (no leading zero) mm - "%m" - month of year (two digit) "%m" M - "%b" - month name short MM - "%B" - month name long y - "%y" - year (two digit) yy - "%Y" - year (four digit) @ - "%s" - Unix timestamp (ms since 01/01/1970) For example: has_field 'start_date' => ( type => 'Date', format => "dd/mm/y" ); or has_field 'start_date' => ( type => 'Date', format => "%d/%m/%y" ); You can also set 'date_end' and 'date_start' attributes for validation of the date range. Use iso_8601 formats for these dates ("yyyy-mm- dd"); has_field 'start_date' => ( type => 'Date', date_start => "2009-12-25" ); Customize error messages 'date_early' and 'date_late': has_field 'start_date' => ( type => 'Date, messages => { date_early => 'Pick a later date', date_late => 'Pick an earlier date', } ); If form has 'is_html5' flag active it will render <input type="date" ... /> instead of type="text" AUTHOR
