html::display
HTML::Display(3pm) User Contributed Perl Documentation HTML::Display(3pm) NAME
HTML::Display - display HTML locally in a browser SYNOPSIS
use strict; use HTML::Display; # guess the best value from $ENV{PERL_HTML_DISPLAY_CLASS} # or $ENV{PERL_HTML_DISPLAY_COMMAND} # or the operating system, in that order my $browser = HTML::Display->new(); warn "# Displaying HTML using " . ref $browser; my $location = "http://www.google.com/"; $browser->display(html => $html, location => $location); # Or, for a one-off job : display("<html><body><h1>Hello world!</h1></body></html>"); DESCRIPTION
This module abstracts the task of displaying HTML to the user. The displaying is done by launching a browser and navigating it to either a temporary file with the HTML stored in it, or, if possible, by pushing the HTML directly into the browser window. The module tries to automagically select the "correct" browser, but if it dosen't find a good browser, you can modify the behaviour by setting some environment variables : PERL_HTML_DISPLAY_CLASS If HTML::Display already provides a class for the browser you want to use, setting "PERL_HTML_DISPLAY_CLASS" to the name of the class will make HTML::Display use that class instead of what it detects. PERL_HTML_DISPLAY_COMMAND If there is no specialized class yet, but your browser can be controlled via the command line, then setting "PERL_HTML_DISPLAY_COMMAND" to the string to navigate to the URL will make HTML::Display use a "system()" call to the string. A %s in the value will be replaced with the name of the temporary file containing the HTML to display. %HTML::Display::os_default The hash %HTML::Display::os_default contains pairs of class names for the different operating systems and routines that test whether this script is currently running under it. If you you want to dynamically add a new class or replace a class (or the rule), modify %os_default : # Install class for MagicOS $HTML::Display::os_default{"HTML::Display::MagicOS"} = sub { $^O =~ qr/magic/i }; __PACKAGE__->new %ARGS $browser->display( %ARGS ) Will display the HTML. The following arguments are valid : base => Base to which all relative links will be resolved html => Scalar containing the HTML to be displayed file => Scalar containing the name of the file to be displayed This file will possibly be copied into a temporary file! location (synonymous to base) If only one argument is passed, then it is taken as if html => $_[0] was passed. EXPORTS
The subroutine "display" is exported by default COMMAND LINE USAGE
Display some HTML to the user : perl -MHTML::Display -e "display '<html><body><h1>Hello world</body></html>'" Display a web page to the user : perl -MLWP::Simple -MHTML::Display -e "display get 'http://www.google.com'" Display the same page with the images also working : perl -MLWP::Simple -MHTML::Display -e "display html => get('http://www.google.com'), location => 'http://www.google.com'" AUTHOR
