I forgot that the new main loop must update the QSyntaxHighlighter state!
Like this:
def newMainLoop(self, n: int, s: str) -> None:
"""Colorize a *single* line s, starting in state n."""
# colorize_line line "s".
state = self.new_mode_module.colorize_line(s, n)
# Set the state for QSyntaxHighlighter!
n = self.computeState(f=None, state=state)
self.setState(n)
*Discussion*
In the old world, updating the QSyntaxHighlighter state happens deep within
the bowels of the pattern matchers, that is, within the so-called "restart"
methods. The old main loop must *not *update the state explicitly!
In contrast, the new main loop *must *update the QSyntaxHighlighter state.
The new scheme should be significantly easier to understand and debug.
