browser::open
Browser::Open(3pm) User Contributed Perl Documentation Browser::Open(3pm) NAME
Browser::Open - open a browser in a given URL VERSION
version 0.03 SYNOPSIS
use Browser::Open qw( open_browser ); ### Try commands specific to the current Operating System my $ok = open_browser($url); # ! defined($ok): no recognized command found # $ok == 0: command found and executed # $ok != 0: command found, error while executing ### Try all known commands my $ok = open_browser($url, 1); DESCRIPTION
The functions optionaly exported by this module allows you to open URLs in the user browser. A set of known commands per OS-name is tested for presence, and the first one found is executed. With an optional parameter, all known commands are checked. The "open_browser" uses the "system()" function to execute the command. If you want more control, you can get the command with the "open_browser_cmd" or "open_browser_cmd_all" functions and then use whatever method you want to execute it. API
All functions are not exported by default. You must ask for them explicitly. open_browser my $ok = open_browser($url, $all); Find an appropriate command and executes it with your $url. If $all is false, the default, only commands that match the current OS will be tested. If true, all known commands will be tested. If no command was found, returns "undef". If a command is found, returns the exit code of the execution attempt, 0 for success. See the "system()" for more information about this exit code. If no $url is given, an exception will be thrown: "Missing required parameter $url". open_browser_cmd my $cmd = open_browser_cmd(); Returns the best command found to open a URL on your system. If no command was found, returns "undef". open_browser_cmd_all my $cmd = open_browser_cmd_all(); Returns the first command found to open a URL. If no command was found, returns "undef". AUTHOR
