This can be bound like `bind \cl clear-screen`, and is, by default
In contrast to the current way it doesn't need the external `clear`
command that was always awkward.
Also it will clear the screen and first draw the old prompt to remove
flicker.
Then it will immediately trigger a repaint, so the prompt will be overwritten.
This was the remaining immediately actionable part of #7375.
It's not definitely the last word, but a change here would require a
bigger plan.
Fixes#7375
This used to print all codepoints outside of the ASCII range (i.e.
above 0x80) in \uXXXX or \UYYYYYYYY notation.
That's quite awkward, considering that this is about keys that are
being pressed, and many keyboards have actual symbols for these on
them - I have an "ö" key, so I would like to use `bind ö` and not
`bind \u00F6`. So we go by iswgraph.
On a slightly different note, `\e` was written as `\c[ (or \e)`. I do
not believe anyone really uses `\c[` (the `[` would need to
be escaped!), and it's confusing and unnecessary to even mention that.
This cleans up the CSS, reduces the number of different colors and special settings we use.
It increases contrast so we now pass WCAG AAA (according to chromium), and switches to css variables for colors to make dark mode simpler to implement.
During development, for a while `path change-extension` would return 0
when it found an extension to change.
This was later changed to returning 0 if there are any path arguments.
Neither of which is *super* useful, I admit, but we've picked one and
the docs shouldn't contradict it.
This was accidentally changed in 3.2.0, when type was made a builtin.
Since it's been 4 releases and nobody has noticed, rather than
breaking things again let's leave it as it is, especially because the
option is named "--no-functions", not "--no-functions-or-builtins".
After accidentally running a command that includes a pasted password, I want
to delete command from history. Today we need to recall or type (part of)
that command and type "history delete". Let's maybe add a shortcut to do
this from the history pager.
The current shortcut is Shift+Delete. I don't think that's very discoverable,
maybe we should use Delete instead (but only if the cursor is at the end of
the commandline, otherwise delete a char).
