Prior to this fix, s_reset would attempt to reset the screen, optionally
using the PROMPT_SP hack to go to the next line. This in turn required
passing in the screen width even if it wasn't needed (because we were
not going to abandon the line). Factor this into two functions:
- s_reset_line which does not apply the hack
- s_reset_abandoning_line which applies the PROMPT_SP hack
common_get_width will "lazily" decide the screen width, which means
changing the environment variable stack. This is a surprising thing
to do from the middle of screen rendering.
Switch to passing in widths explicitly to screen.
The removed comparison ({begin,end,field} == INT_MIN) always evaluates
to false, because at this point in evaluation, `begin <= 0` has already
been evaluated to be false. Since INT_MIN <= 0, the second conditional
in all three of the affected cases is always false. The C++ standard
seems to guarantee left-to-right evaluation of logical operators, but
not necessarily bitwise operators.

With the new pexpect based framework, bind and pipeline expect tests can
be removed.
Amusingly the complete.fish check required the existence of bind.expect.
Fix the check at the same time.
Make it easier to use pexpect and to understand its error messages.
Switch to a style in tests using bound methods, which makes them
less noisy to write.
This adds a new interactive test framework based on Python's pexpect. This
is intended to supplant the TCL expect-based tests.
New tests go in `tests/pexpects/`. As a proof-of-concept, the
pipeline.expect test and the (gnarly) bind.expect test are ported to the
new framework.
We are 1-indexed, and so it's weird to have `test` count its arguments
from 0.
For `test 1 =` this changes the error from
test: Missing argument at index 2
1 =
^
to
test: Missing argument at index 3
1 =
^
test loves error messages like
test: Missing argument at index 2
without explaining where that "index 2" is.
So now, we print the arguments below that, with a caret pointing to
the place where the error occured.
For example:
> test 1 = 2 and echo true or echo false
test: Expected a combining operator like '-a' at index 3
1 = 2 and echo true or echo false
^

Fixes#6030.
* docs/faq: Mention prepend_sudo
[ci skip]
* __fish_prepend_sudo: Use $history[1] if commandline is empty
Currently, if you press alt+s with an empty commandline, it inserts
"sudo", which seems fairly useless.
Now, it inserts "sudo " followed by the last history entry, which
makes it a replacement for `sudo !!`.

There's a terrible number of fishscripts that start with
set path (dirname (status filename))
And that's really just a bit boring.
So let's let it be
set path (status dirname)
This reverts commit 1b0ec21773.
"Interactive" has multiple meanings here, one of them being "the whole shell" is interactive, which `status is-interactive` tests, and one "this interaction is interactive", which happens when `read`ing in a script.
Fixes#7080.
This change is necessary to fix dynamic titles for the Alacritty
terminal. We do this by simply adding the (wchar_t *) literal
L"alacritty" to the end of the title_terms array. This variable is
ultimately used in the subsequent function
does_term_support_setting_title (dtsst) for the purposes of whitelisting
certain terminals.
If an Alacritty user does not have the terminfo for alacritty present in
their terminfo database, Alacritty sets the TERM variable to
"xterm-256color", but if the terminfo for Alacritty is present, TERM is
instead set to "alacritty".
Prior to this change, none of the "fallback patterns" in the dtsst
function (which is used to ultimately decide whether or not a given
value of the TERM environment variable is supported) would apply to a
value of "alacritty". Ordinarily, the dtsst function would return true
if nothing matches, but one of the final checks involves testing the
result of ttyname_r to see if it contains the substring "tty", which
causes dtsst to return false. In the case where TERM="alacritty", this
is erroneous, because Alacritty does, indeed, support changing its title
and will also silently ignore attempts to change the title if that
behavior has been disabled by the user [1].
The changed file, src/env_dispatch.cpp, was reformatted by clang-format
in accordance with the documented procedures for contributors.
