deephaven-plugin-ui 0.11.0

deephaven.ui plugin

deephaven.ui Plugin

Plugin prototype for programmatic layouts and callbacks. Currently calling it deephaven.ui but that's not set in stone.

Build

To create your build / development environment (skip the first two lines if you already have a venv):

python -m venv .venv
source .venv/bin/activate
pip install --upgrade pip setuptools
pip install build deephaven-plugin plotly

To build:

python -m build --wheel

The wheel is stored in dist/.

To test within deephaven-core, note where this wheel is stored (using pwd, for example). Then, follow the directions in the top-level README.md to install the wheel into your Deephaven environment.

To unit test, run the following command from the root of the repo:

tox -e py

Usage

Once you have the JS and python plugins installed and the server started, you can use deephaven.ui. See examples for examples.

Logging

The Python library uses the logging module to log messages. The default log level is WARNING. To change the log level for debugging, set the log level to DEBUG:

import logging
import sys

# Have the root logger output to stdout instead of stderr
logging.basicConfig(stream=sys.stdout, level=logging.WARNING)

# Set the log level for the deephaven.ui logger to DEBUG
logging.getLogger("deephaven.ui").setLevel(level=logging.DEBUG)

You can also set the log level for specific modules if you want to see specific modules' debug messages or filter out other ones, e.g.

# Only log warnings from deephaven.ui.hooks
logging.getLogger("deephaven.ui.hooks").setLevel(level=logging.WARNING)

# Log all debug messages from the render module specifically
logging.getLogger("deephaven.ui.render").setLevel(level=logging.DEBUG)
