Updated requirements and adjusted the configuration in `.flake8`; other
files have been modified where the lack of per-file auto-ignore caused
problems, where putty's `# flake8: disable=` syntax could be replaced
with a simpler `noqa`, or where pylint directives already suppressed the
same error.
When doing :unbind with a default keybinding the first time, it gets inserted
into bindings.commands with None as value.
When then doing :unbind a second time, instead of just leaving that None value
as-is, we removed it again (because it got treated as a custom binding).
Fixes#3162
Turns out --force is just in the way for most people, and at least for default
bindings it's easy to reset them.
Also, it makes :config-source fail when config.py contains keybindings.
Closes#3049
There are just way too many gotchas related to valid modes, aliases, and
circular dependencies when validating aliases/bindings in the config.
Let's just remove this and let invalid commands fail late, when they're actually
used.
I considered introducing another list of deleted options (or a "deleted: True"
in configdata.yml), similar to what we had with the old config.
However, let's take the easier route and just delete everything we don't know
from configdata.yml. If someone edits it by hand, it's their fault :P
See #2772, #2847
We accidentally did show the command as a list in to_str(). However, after
correcting that to use shlex.escape, we got ugly qutebrowser command lines
when tabbing to the default value, because of how shlex handles double-escaping:
>>> print(shlex.quote("gvim -f '{}'"))
'gvim -f '"'"'{}'"'"''
While in this case, outputting "gvim -f '{}'" would be much more appropriate, it
doesn't look like we can teach shlex.quote to do that.
Instead, we now only accept a list as input for ShellCommand, at the price that
the user needs to do
:set editor.command '["gvim", "-f", "{}"]'
instead of
:set editor.command 'gvim -f {}'
Fixes#2962.
