This searched for package.json in any parent, so just like finding
.git and .hg directories it _needs_ to use the physical pwd because
that's what git/hg/yarn use.
In general, if you do _any_ logic on $PWD, it should be the physical
path. Logical $PWD is basically only good for display and cd-ing
around with symlinks.

This merges a bunch of changes that clean up how the reader loop and input
works.
Prior to this fix, we abused wchar_t by cramming readline functions into
"private" regions. Readline functions then were further abused with
meta-readline functions like R_NULL or R_TIMEOUT.
This fix introduces a new type char_event_type_t which wraps up the "meta"
character types. A char event may be a null (try again), timeout, readline,
or real input character. These are all distinct values.
The reader loop is then refactored to handle these cases separately.
I believe this was selected to be artificially low for the sake
of it displaying well in prompts. But people should expect to get
the same output as can be gotten from `hostname`.
Fixes#5758
This called `eval $fish_browser --version` to figure out if it is
lynx.
That's really not worth it just to support edge-cases using a rather
unusual browser, to work around a bug in it.
Instead we just see if the browser name starts with "lynx", which
should work in 99.9% of cases.
This merges in a number of improvements specifically aimed at console
sessions (i.e. using fish at the tty, not over SSH or in an X-based
terminal emulator). When a console session is detected, the system
wcwidth is used to line up width info between fish and the system tty,
and only simple characters are used as symbols.
Tested under Linux, macOS, FreeBSD, Solaris, Cygwin, WSL, and others.
Closes#5552. Ref #789, #3672.
The code already allowed for variable width (multicell) *display* of the
newline omitted character, but there was no way to define it as being
more than one `wchar_t`.
This lets us use a string on console sessions (^J aka newline feed)
instead of an ambiguous character like `@` (used in some versions of
vim for ^M) or `~` (what we were using).
The system version of `wcwidth()` reflects the capabilities of the
system's own virtual terminal's view of the width of the character in
question, while fish's enhanced version (`widechar_wcwidth`) is much too
smart for most login terminals, which generally barely support anything
beyond ASCII text.
If, at startup, it is detected that we are running under a physical
console rather than within a terminal emulator running in a desktop
environment, take that as a hint to use the system-provided `wcwidth`.
The commit began passing the length of the wide string rather than the
length of the narrowed string after conversion via `wcstombs`. We *do*
have the actual length, but it's not (necessarily) the same as the
original value. We need to pass the result of `wcstombs` instead.
This created another local version of the variable just for the if-block.
Can't say I love the space prefix, but then I think we have too many
of these modes anyway.
If you use these to figure out if there _are_ staged files, or dirty
or whatever, you currently need to check the output, which relies on
the configured character.
Instead, we let them also return a useful status.
Notably, this is *not* simply the status of the git call.
__fish_git_prompt_X returns 0 if the repo is X.
This works for untracked, but the "diff" things return 1 if there is a
diff, so we invert the status for them.
See #5748.

POSIX dictates here that incomplete conversions, like in
printf %d\n 15.2
or
printf %d 14g
are still printed along with any error.
This seems alright, as it allows users to silence stderr to accept incomplete conversions.
This commit implements it, but what's a bit weird is the ordering between stdout and stderr,
causing the error to be printed _after_, like
15
14
15.1: value not completely converted
14,2: value not completely converted
but that seems like a general issue with how we buffer the streams.
(I know that nonfatal_error is a copy of most of fatal_error - I tried
differently, and va_* is weird)
Fixes#5532.
Before this change, - was sorted with other punctuation before
A-Z. Now, it sorts above the rest of the characters.
This has a practical effect on completions, where when there are
both -s and --long with the same description, the short option
is now before the long option in the pager, which is what is now
selected when navigating `foo -<TAB>`. The long options can be
picked out with `foo --<TAB>`. Before, short options which
duplicated a long option literally could not be selected by
any means from the pager.
Fixes#5634
This tweaks wcsfilecmp such that certain punctuation characters will
come after A-Z.
A big win with `set <TAB>` - the __prefixed fish junk now comes
after the stuff users should care about.
