Createlinks example script

	Skill level: Developer
	Risk of inconsistencies with Koozali SME Server methodology, upgrades & functionality is high. One must be knowledgeable about how changes impact their Koozali SME Server. Significant risk of irreversible harm.

The build section lists commands to run as part of the build process This is where you can use a root/createlinks script to create events and action links. see

• Esmith::Build::CreateLinks
• SME_Server:Documentation:Developers_Manual#The_createlinks_script

%build
perl createlinks

Example 1

#!/usr/bin/perl -w

sub safe_symlink {
   my ($from, $to) = @_;
   use File::Basename;
   use File::Path;
   mkpath(dirname($to));
   unlink($to);
   symlink($from, $to) or die "Can't create symlink from $from to $to: $!";
}
sub panel_link

{
 my ($function, $panel) = @_;
    safe_symlink("../../../functions/$function",
         "root/etc/e-smith/web/panels/$panel/cgi-bin/$function");
}
sub event_link

{

   my ($action, $event, $level) = @_;
    safe_symlink("../actions/${action}",
               "root/etc/e-smith/events/${event}/S${level}${action}");
}
 #--------------------------------------------------
 # functions for manager panel
 #--------------------------------------------------
panel_link("yum", "manager");

   #--------------------------------------------------
   # actions for yum-update event
   #--------------------------------------------------

Example 2 : Sme8admin

safe_symlink("/etc/e-smith/web/panels/manager/html/sme8admin", "root/etc/e-smith/web/panels/user/html/sme8admin");

# Logrotate
