Add-ons

Extensions to UDB are available in the form of add-ons. Unlike an Undo release, add-ons can be introduced and updated at any time.

Generally, add-ons operate by adding new UDB commands. Help text is displayed when an add-on is installed, but for full details it is possible to browse the source repository.

Add-ons are installed using the extend [add-on] command. Once installed, add-ons remain installed until the end of the current UDB session only. To make an add-on persist, add the extend command to an initialization file (see Initialization files). Add-ons cannot be uninstalled during a UDB session.

Warning

Add-ons are fetched from github.com. Do not install add-ons if your organization’s security policy forbids it.

extend [add-on]

Install an add-on.

If add-on is omitted, then all available add-ons are listed.

The machine where UDB is run must be able to reach github.com and raw.githubusercontent.com.
