Gramex 1.32 Release Notes

Logviewer configuration

Log viewer is now configurable. When importing logviewer, you can:

• configure the dashboard layout
• add additional panels
• schedule the log viewer as required

Gramex init

gramex init now adds a .stylelintrc file that checks for CSS issues. The .htmllintrc file is also improved

Tornado 5.0

Gramex now supports Tornado 5.0 on Python 3. Tornado 5.0 uses the native asyncio library. This meant re-writing some of Gramex’s internals.

There are still a few kinks to sort out, though.

YAML merge variables

gramex.yaml supports an import.merge: key that copy-pastes a configuration in-place. This is mainly used when writing re-usable Gramex applications / services. See merging variables.

CaptureHandler Proxy

CaptureHandler with Chrome respects proxy environment variables. If your proxy IP is 10.20.30.40 on port 8000, then set ALL_PROXY, HTTPS_PROXY or HTTP_PROXY to 10.20.30.40:8000.

Internal bugfixes

Gramex internals have a few important bug fixes.

• Changing the Gramex configuration used to re-initialize configurations even if they hadn’t changed. This is resolved.
• If multiple instances of Gramex are running, this caused shared sqlite sessions to report errors on already purged keys. This is resolved.

Stats

• Code base: 23,896 lines (python: 14,928, javascript: 1,231, tests: 8,074)
• Test coverage: 79%

Upgrade

To upgrade Gramex, run:

pip install --verbose gramex==1.32

This downloads Chromium and other front-end dependencies. That may take time.
