ackandClaude Fable 5.1 89b4a41b2a Character codes in typed text; the site and relay at app.kokkoja.com
With the Text tool, Klammertext's codes give letters a keyboard lacks:
^o" is ö, ^s^ ß, ^a1 ā, ^130ED^ a code point of 4 to 6 digits,
^9053 53EF^ a sequence, ^^ a caret, replaced as each code is completed.
The public site and relay moved to app.kokkoja.com; the old name
redirects.  The Markdown documentation is withdrawn from the release
while it is converted to Klammertext; the README's links to it are
stale until then.

Kokkoja

Kokkoja lets people at different computers write together on a shared page, by hand or by typing, with every page saved automatically to each person's own notebook. It runs in a web browser beside a video call and replaces the call's screen sharing and annotation. It was made first for teaching a foreign language over a video call, and it serves any work that two or more people would otherwise do over one sheet of paper.

Kokkoja is free software under the GNU General Public License, version 3 or later: see LICENSE.md, which also says how the name may be used.

Documentation

In short

A guest needs nothing but a web browser: open the invitation link, enter a name, join. A host can start a session from the same web site, https://app.kokkoja.com/, with the notebooks kept in the browser.

A host who wants notebooks as files needs Python 3 and this directory:

python3 kokkoja.py --relay wss://app.kokkoja.com/relay

opens Kokkoja in the browser; Start a session gives an invitation to send to the guests. Notebooks are directories in Kokkoja in the Documents directory.

What is here

  • kokkoja.py: the local program, which serves the client to your browser and keeps your notebooks as files. Python standard library only.
  • client/: the client, plain JavaScript modules run by the browser as written.
  • relay/: the relay server, Python with the websockets library.
  • deploy/: how a Kokkoja server is set up (relay plus web site).
  • docs/: the documentation above.
  • tests/: the tests (python3 -m unittest discover tests); the end-to-end test needs Firefox and geckodriver, and the QR code's test needs Node.js and pip install -r tests/requirements.txt.
  • LICENSE.md: the license.
