Log messages have been re-written with structured fields.
Also, important Go depenedencies like x/sys and errors packages have
been updated.
Github actions have also been updated.
Switched to Go1.21 to use the log/slog package for strutctured logging.
TODO: Log messages that are stringifying objects can now use strutctured
output.
TODO: Customise log levels for different messages.
Fix tests
No doubt a lot of this code is reinventing the wheel, after all this is
basically now a simple text editor. I'm sure there'll be a few bugs to
iron out.
Unit tests needed tab objects to be created.
Integration tests needed more max time for start up and to make sure
that the final tab doesn't get closed.
Adding, cycling, deleting. The width of the tab handle is currently
fixed to 20. And if there are more tabs than can fit in the tab bar then
the extra ones just dissapear off to the right, but they can still be
cycled to with CTRL-Tab.
The marks the end of feature development in preperation for a version
1 release.
Input boxes are currently only one line and to not properly wrap. So
textareas are also one line. TBC...
Also includes:
* First implementation of the DOM MutationObserver. This needs to have
an eye kept on it in case some websites trigger too mutatation
events. For now it doesn't seem too bad. Although strangely it seems
to stop on Youtube after about 15 seconds.
Firstly, this improves performance on a larger pages. But it also
prevents browser crashes a very large pages by setting a limit to how
much work is done per frame.
Also includes:
* Thread safe cell map for simultaneously reading and writing to the
buffered frame of TTY cells.
* Improved webext tests so that they programmaticlly build DOM rects
based off simple text strings.
* CLI is now prepared for supporting multiple tabs.
* Refactored global vars into relevant files
* Now using real types in JSON sent to CLI
* Still doesn't fix integration tests
This offloads significant CPU load from the browser. However it's become
clear that the previous feature of parsing the entire DOM needs to have
an upper limit imposed. For instance large Wikipedia pages still cause
problematic CPU load.
This commit does not fix the broken UI so integration tests fail.
