Deephaven in VS Code
- Run Python dh scripts from vscode against a running DH core server
- Run all
- Run selected code
- View output in vscode panels
Note: There are some
vscode
bugs that cause some flakiness with therun
button. vscodev90
introduced an optionalworkbench.editor.alwaysShowEditorActions
setting. Setting this totrue
improves the experience here. Namely the run button will not disappear when running commands or selecting its dropdown. See #1 for more details.
Core server http://localhost:10000/
is configured by default and doesn't require any additional config. Additional connections can be configured in vscode
settings.
e.g. .vscode/settings.json
{
// Core servers
"vscode-deephaven.core-servers": [
"http://localhost:10000/",
"http://localhost:10001"
]
}
To select the active connection that scripts will be run against, click the connection picker in the bottom status bar of vscode.
Note: If you don't select a connection, the first one will be automatically used the first time a script is run.
Then select one of the servers:
Scripts will be run against the active connection or default to the first connection if none is selected.

The vscode-deephaven
extension comes with some predefined python
snippets. These insert pre-defined code snippets into an editor. To use, simply type ui
in an opened python
file to see available snippets.
