Replace the setting ui.show-keyhints with ui.keyhint-blacklist, which
is a list of globs for keychains that shouldn't be hinted. This allows
users to prevent showing keyhints for keychains they already know.
keyhint-blacklist='*' is equivalent to show-keyhints=False.
Resolves#1515.
If a user knows the keychain and can type it quickly, we shouldn't
annoy them with a popup. Only show the keyhint if the user doesn't
complete their keychain in 500ms.
The isVisible() check in the tests is somewhat invalid now because it
is never immediately visible and I don't want to add a delay to unit
tests. I added a check that text() is not set for one test that was
only checking isVisible().
Addresses part of #1515.
The check `key.startswith('<') and key.endswith('>') is repeated many
times in code to check for a special key. Replace all these with a call
to the same function.
Currently, the keyhint window is shown even if the keystring matches no
possible bindings. This causes an empty keyhint window to hang around
after entering hinting mode.
Instead, the window is now hidden if no bindings match the current
keystring.
Resolves#1507.
This means:
- An annotation like (int, str) is now typing.Union[int, str].
- utils.typing got expanded so it acts like the real typing.py, with
issubclass() working properly with typing.Union and __union_params__
being set.
- A literal string doesn't exist anymore as annotation, instead
@cmdutils.argument now has a 'choices' argument which can be used like
@cmdutils.argument('arg', choices=['val1', 'val2']).
- Argument validating/converting is now entirely handled by
argparser.type_conv instead of relying on python's argparse, i.e.
type/choices is now not passed to argparse anymore.
Previously, negative bottom padding was used (probably to compensate
for a trailing <br>). With the table format, this is no longer
necessary and causes the last line to be drawn too low.
Don't show special keys in the keyhint window as these currently cannot
be part of keychains.
Use a rounded border on the top-right corner and square on the rest.
From code review:
- escape all strings used in the keyhint html
- read the prefix color each time the hint is shown
- use show/hide instead of setVisible
- clean up pylint/flake8 errors
- use CssColor instead of QssColor for keyhint.fg.suffix
- add some padding to the keyhint popup
When the current keystring is a partial match for one or more bindings,
show the possible bindings in a small overlay.
The overlay is partially transparent by default, but the background
color is configurable as ui->keystring.bg.
Before we used a {'nargs': '*'} annotation for the respective argument
to tell qutebrowser it's optional for the commandline. Now we instead
use a star_args_optional argument for @cmdutils.register as a first step
towards freeing up argument annotations for PEP 484.
