Sharif and I had a three-hours session for #3049 (Websocket connection in React for notifications). Before this, Saturday, we had a historic meeting where Hamza joined us and presented what he had done on use_websockets two years ago.

Now Sharif and I moved use_websockets and use_push_api from Site to the lino.modlib.notify plugin. They are no longer site attributes but plugin options. The lino_book.projects.chatter demo project will be the only place where

The use_push_api option means that Lino uses the Push API for sending notifications.

I installed pywebpush and ngrok (pronounced [en-grok]) on my machine.

We had some fiddling with git because I still don’t fully understand how to work with remote branches. Some excerpts to be integrated into Git cheat sheet:

$ git branch --track remote_branch

$ git stash save
Saved working directory and index state WIP on master: 0d9947c2 fix 2 warnings term not in glossary
$ git stash pop

$ git branch -u origin/blurry blurry
Branch 'blurry' set up to track remote branch 'blurry' from 'origin'.

$ git branch -u origin/blurry blurry
error: the requested upstream branch 'origin/blurry' does not exist
hint: If you are planning on basing your work on an upstream
hint: branch that already exists at the remote, you may need to
hint: run "git fetch" to retrieve it.
hint: If you are planning to push out a new local branch that
hint: will track its remote counterpart, you may want to use
hint: "git push -u" to set the upstream config as you push.

How to fetch a remote branch and start tracking it:

git fetch blurry:blurry

How to see whether my branches are remote:

git branch -vv

Situation: I am on master. Sharif created and pushed a new remote branch blurry. To see his work, I do:

git checkout -b blurry origin/blurry

See man git checkout.
