Extension Management

Extensions are custom pieces of software, produced by GB and third-parties, that “extend” the capabilities of CAS. Extension guidelines and examples can be found on our GitHub presence at:

General Bytes on Github

Any and all documentation about extensions are confined to our GitHub site. General Bytes' Support is limited to existing hardware and software only. Support cannot and will not assist in your creation of custom code. That exploration is outside the scope of our Support. Questions may only be fielded to the community and development team via standard GitHub channels.

Installing an Extension

Once the extension is built, it may be loaded into CAS.

Copy the “jar” file to the extensions folder

cp /root/your_custom_extension.jar /batm/app/master/extensions/your_custom_extension.jar

the filename and location will obviously be different.

Modify file ownership:

sudo chown batm:batm /batm/app/master/extensions/your_custom_extension.jar

the custom extension must be “owned” by the batm user.

Modify the extension configuration file:

Create the /batm/config/extensions file and adjust it's permissions:

sudo mkdir -p /batm/app/master/extensions
sudo touch /batm/config/extensions
sudo chown batm:batm /batm/config/extensions

Use nano (or another editor) to edit the “extensions” configuration file:

sudo nano /batm/config/extensions

set autoload=true for the jar’s extension.
com.generalbytes.batm.server.extensions.your_custom_extension.autoload=true

Save the file and exit nano (Ctrl+X and Enter).

Restart CAS to implement the new extension.

sudo /batm/batm-manage stop all
sudo /batm/batm-manage start all

Success. The JAR is now in the proper place, and CAS will load it when started.

To verify it is enabled, navigate (in CAS) to: Tools > Loaded extensions

Your custom extension should be listed.

Disabling an Extension

Third-party extensions will normally need testing & debugging. To disable an extension for debugging:

Use nano (or another editor) to edit the “extensions” configuration file:

sudo nano /batm/config/extensions

set autoload=false for the jar’s extension.
com.generalbytes.batm.server.extensions.your_custom_extension.autoload=false
Save the file and exit nano (Ctrl+X and Enter).

Restart CAS to implement the new extension.

sudo /batm/batm-manage stop all
sudo /batm/batm-manage start all

To verify it is disabled, navigate (in CAS) to: Tools > Loaded extensions:

Your custom extension should NOT be listed.
