A lot of Hop’s default behavior can be customized through global variables. Check full list of variables to check them all. A couple of useful and often overlooked environment variables can be set (outside of Hop):
Set this variable to a valid path on your machine to store Hop’s audit information. This information includes last opened files per project, zoom size and lots more.
Hop stores your configuration in the
configfolder by default. Set this environment variable to point to a folder outside of your Hop installation to keep your configuration, projects and environment list etc, no matter which Hop version or installation you use.
Set this variable to point Hop to a comma separated list of folders where you want Hop to look for additional plugins.
| When using this variable it will also unset your default plugins folder, make sure to add the default plugin folder to the comma separated list. This can be a relative path to the installation eg. |
The variable which points to a shared folder with JDBC drivers in them.
Keyboard Shortcuts and Mouse actions
In any table view in a Hop dialog, select one or more lines and use
CTRL-Kto remove all lines but your selection
Hover your mouse pointer over any pipeline action in a workflow, pipeline or workflow executor transform etc and use
CTRL-SHIFT-Clickto open that item in a new tab. The same behavior can be triggered by hovering over an item and hitting the
- Copy as pipeline action
In any pipeline or workflow, click anywhere on the canvas and choose 'Copy as pipeline action' or 'Copy as workflow action'. The selected pipeline or workflow can now be pasted (CTRL-V) as a fully configured workflow or pipeline action in any workflow.

- Action or transform hover +
Hover your mouse pointer over any pipeline action in a workflow, pipeline or workflow executor transform etc and hit the
Zkey to open that item in a new tab. The same behavior can be triggered by hovering over an item and hitting the use
Projects and Environments
Projects can inherit metadata items (e.g. database connections) from parent projects. Use parent projects to reuse metadata items across multiple projects.
a best practice rather than a pro tip: use project variables only for variables that are valid across all environments. Variable that have different values in different environments should be created on the environment level.
