| <title>HostInfo Task</title> |
| </head> |
| |
| <body> |
| |
| <h2><a name="hostinfo">HostInfo</a></h2> |
| |
| <h3>Description</h3> |
| <p>Sets the <code>NAME</code>, <code>DOMAIN</code>, <code>ADDR4</code>, and <code>ADDR6</code> |
| properties in the current project.</p> |
| <p> |
| The <code>NAME</code> contains the host part of the canonical name of the host.<br/> |
| If the host is not found, the host will contain the name as provided to the task, |
| or <code>localhost</code> if no host was provided, and no name for the local |
| host was found.<br/> |
| The <code>DOMAIN</code> contains the domain part of the canonical name of the host.<br/> |
| If the host is not found, the domain will contain the domain as provided to the task, |
| or <code>localdomain</code> if no host / domain was provided.<br/> |
| The <code>ADDR4</code> contains the IPv4 address of the host with the widest meaning.<br/> |
| If no IPv4 address is found and a host has been provided the address <code>0.0.0.0</code> |
| is returned, when no host was provided the address <code>127.0.0.1</code> is returned.<br/> |
| The <code>ADDR6</code> contains the IPv6 address of the host with the widest meaning.<br/> |
| If no IPv6 address is found and a host has been provided the address <code>::</code> |
| is returned, when no host was provided the address <code>::1</code> is returned.<br/> |
| </p> |
| |
| <p>These properties can be used in the build-file, for instance, to create |
| host-stamped filenames, or used to replace placeholder tags inside documents |
| to indicate, for example, the host where the build was performed on. |
| The best place for this task is probably in an initialization target.</p> |
