otterwiki (via) It's been a while since I've seen a new-ish Wiki implementation, and this one by Ralph Thesen is really nice. It's written in Python (Flask + SQLAlchemy + mistune for Markdown + GitPython) and keeps all of the actual wiki content as Markdown files in a local Git repository.
The installation instructions are a little in-depth as they assume a production installation with Docker or systemd - I figured out this recipe for trying it locally using uv:
git clone https://github.com/redimp/otterwiki.git
cd otterwiki
mkdir -p app-data/repository
git init app-data/repository
echo "REPOSITORY='${PWD}/app-data/repository'" >> settings.cfg
echo "SQLALCHEMY_DATABASE_URI='sqlite:///${PWD}/app-data/db.sqlite'" >> settings.cfg
echo "SECRET_KEY='$(echo $RANDOM | md5sum | head -c 16)'" >> settings.cfg
export OTTERWIKI_SETTINGS=$PWD/settings.cfg
uv run --with gunicorn gunicorn --bind 127.0.0.1:8080 otterwiki.server:app

Async functions require an event loop to run. Flask, as a WSGI application, uses one worker to handle one request/response cycle. When a request comes in to an async view, Flask will start an event loop in a thread, run the view function there, then return the result.
Each request still ties up one worker, even for async views. The upside is that you can run async code within a view, for example to make multiple concurrent database queries, HTTP requests to an external API, etc. However, the number of requests your application can handle at one time will remain the same.
New Major Versions Released! Flask 2.0, Werkzeug 2.0, Jinja 3.0, Click 8.0, ItsDangerous 2.0, and MarkupSafe 2.0. Huge set of releases from the Pallets team. Python 3.6+ required and comprehensive type annotations. Flask now supports async views, Jinja async templates (used extensively by Datasette) “no longer requires patching”, Click has a bunch of new code around shell tab completion, ItsDangerous supports key rotation and so much more.

Do Flask and Django have a GUI interface like web2py?
No. The web2py GUI is something of an oddity in the Python world.

Do Python programmers have a tendency to write their own software instead of contributing? Why?
I think you’ll find that PROGRAMMERS have a tendency to develop their own thing rather than contributing to an existing project. It’s even got its own TLA: NIH (Not Invented Here).

Flask 0.1 Released. Armin’s Flask (a Python microframework built around Werkzeug and Jinja2) is looking pretty solid for a two week old project—extensive documentation, comprehensive unit test support (and example applications with unit tests) and some very tidy API design.
