If we don't do this, when doing:
self.config_stub.val.content.user_stylesheets = css_path
then _update_stylesheet gets called before the stylesheet QWebEngineScript did
run (as there was no load yet), so we get:
[:2] Uncaught TypeError: Cannot read property 'stylesheet' of undefined!
Instead, load the page first and then update the stylesheet.
This tests that live updating works properly, and also makes sure we don't run
into the problem described above.
- Initialize JavaScript in webenginesettings.py instead of webenginetab.py
- Move JavaScript snippet into a .js file
- Make sure scripts can be re-run and do nothing if already run.
- Run scripts on DocumentCreation *and* DocumentReady. Closes#3717.
- Give each script an unique name for debugging.
- Also make custom stylesheets work on chrome:// pages
- Use qutebrowser-editor-backup as the backup file prefix
- Consistently use message.error instead of cmdexc
- Improve test coverage for the backup function
- Fix lint errors in the unit test code
Currently the editor deletes its temp file whenever editing is finished.
With this patch, the file will not be deleted if the editor callback
encounters an exception.
One example is if the tab containing the edited element is closed. The
editor errors with "Edited element vanished", but with this patch it
will also print "Backup at ..." so the user does not lose their work.
Resolves#1596.
Supersedes #3641, using the cleaner approach started in #1677.
1899e313fd as a fix for #3631 broke :unbind, as
the config system treats None and '' equally.
Instead, allow None/'' again, but just handle it as "no binding".
This mostly reverts 4ef5db1bc4 for #1966, but
fixes#3684 by allowing numbers to be bound again. If the user wants to bind
numbers instead of using them for a count, why not let them.
