This prints a description of the "host". Currently that's
`(chroot:debianchroot) $USER@$hostname`
with the chroot part when needed.
This also switches the default and terlar prompts to use it, the other
prompts have slightly different coloring or logic here.
Some features:
- A nice `►` prompt char with a fallback for non-utf8 systems
- The $PWD is colored depending on its sha, so different directories
are colored differently, but each directory stays the same
- User@Host is only shown if not on the local machine (ssh or
virtualization)
- A right prompt with a nice git display, date, duration of the last
command (if it took over 100ms), and virtualenv
This gets fish to print the right prompt of any sample if it has any,
and then shows it separately.
If there is a right prompt, it will also save it. If not, it will *not* overwrite an existing right prompt.
This should be a simple prompt that doesn't place a huge strain on the
system but communicates the most important information simply and
effectively.
It should be a good jumping off point for making your own prompt.
Unless that person directly contributed the prompt.
We name them after a feature - the Scales prompt feature a ">>>" which
kinda looks like fish scales, the "Arrow" prompt starts with a
prominent "➜".
Naming them after people looks like an endorsement of that particular
person, and like they are someone to look up to, especially when they
aren't involved with the project.
The "terlar" and "acidhub" prompts stay for now because they
contributed the prompt themselves, they are also much less prominent.
The "classic" prompts are all just variations on a theme, let's just
keep the default classic+vcs.
"Justadollar" is very unlikely to be what you want and also trivial to
write yourself.
I have no idea what screen_savvy even is for - it reacts to "$WINDOW",
but I don't know anything that even uses that variable.
Lonetwin is just unremarkable, and the debian chroot prompt has one special feature that should be integrated into the other prompts.
I ran into problems described in https://github.com/fish-shell/fish-shell/issues/718 when using this prompt. This seems to be a bug in the prompt -- this change fixes it, at least on my system.
I tried this in tmux (TERM=screen) and gnome-terminal (TERM=xterm-256) with fish 3.1.2, on Linux.
Fix 1: The --quiet flag must be at the end of the command. The way it was I would never get any status symbol in my prompt as the command failed.
Fix 2: After adding files to git, but before committing them, git status is unsorted. This gave me the output "M A M A" after `uniq`, which resulted in 4 status symbols instead of 2. Sorting them before filtering them fixed the problem.
Commit 5d135d555 (prompts: fix pipestatus for jobs prefixed with "not")
introduced a backwards compatibility hack about adding an optional argument
to __fish_print_pipestatus. This hack would break downgrading to fish 3.1.2
if the user copied the new prompt to their config - they would get a backtrace
on every prompt which is arguably worse than the patch's minor improvement.
This does away with the error trace - old fish just won't show the fancy
new pipestatus on `not true`.
Implemented by passing the last $status as the poor man's kwarg, which works
since 3.1.0 (9b86d5dd1 Export all local exported variables in a new scope).
The prompts don't work with fish 3.0.0 or older; downgrading does not seem
too important in general but I think this patch is an okay simplification.
These passed " [" to __fish_print_pipestatus as the left brace.
If the color contained a background, that would also color the space
in, leading to a weird unbalanced space before and none after.
Instead, prepend the whitespace when printing later.

Add a helper function to check if the user is root. This function can be
useful for the prompts for example. Modify the prompts made root checked
to use the function instead. Add also the support of Administrator like
a root user.
Fixes: #7031
I kinda hate how fussy clang-format is. It reflows text
constantly (line limit), forces things onto one line *except* when
they're too long, and wants to turn this:
```c++
return true;;
```
into this:
```c++
return true;
;
```
instead of, you know, eliminating the second semicolon?
Anyway, it is what it is and we use it, I'll just look into getting some
more slack.
The default indicator ruined alignment, which is a major design
feature here.
Handle it by including the mode indicator in the prompt proper.
Fixes#6802.

6902459566 was an attempt to not print
$status twice in the prompt. As a result we print $pipestatus but
not $status, which /usually/ is the same as $pipestatus[-1] --- unless
the builtin "not" is used, which inverts the $status of a job (it does
not alter $pipestatus).
As a result, the default prompt prints unexpected status codes:
~ > not false
~ [1]> not true
~ > not true | true
~ > not false | false
~ [1|1]>
This commit reintroduces printing of $status after $pipestatus, but only
if it is different from $pipestatus[-1].
Additionally, we only print anything at all if the $status is nonzero,
to avoid confusing output on `not false | false`
~ > not false
~ > not true
~ [0] 1> not true | true
~ [0|0] 1> not false | false
~ >
I think this is closer to users' expectations for those cases; they should
not have to think about this implementation detail of the not-statement.
It's now good enough to do so.
We don't allow grid-alignment:
```fish
complete -c foo -s b -l barnanana -a '(something)'
complete -c foo -s z -a '(something)'
```
becomes
```fish
complete -c foo -s b -l barnanana -a '(something)'
complete -c foo -s z -a '(something)'
```
It's just more trouble than it is worth.
The one part I'd change:
We align and/or'd parts of an if-condition with the in-block code:
```fish
if true
and false
dosomething
end
```
becomes
```fish
if true
and false
dosomething
end
```
but it's not used terribly much and if we ever fix it we can just
reindent.
This removes a call to `sed` and allows the user to specify shortening
via the variable.
We still default to disabling shortening because this prompt never
did.

This is part of our (well, my) quest to spice up the default prompt.
In this case we color the host if $SSH_TTY is set, which is easy to
detect and helps draw attention to the host.
See #6398.
See #6375.
This was mostly dead, since $fish_color_host is set to normal in
__fish_config_interactive. The assignment was only used if the user
explicitly unsets fish_color_host (which they shouldn't, really).
Anyway it's weird to use cyan, use normal instead.
[ci skip]
The colors are set in __fish_config_interactive before the prompt is
painted for the first time.
Also initialize the $fish_color_status for the (pipe) status, bump the
version for that.
[ci skip]
If a command fails, print the pipestatus in red instead of yellow and
don't print the status of the last process again. See #6375.
Also use $fish_color_status for coloring status consistently.
Also use __fish_pipestatus_with_signal to print SIGPIPE instead
of a numeric code on e.g.: yes | less +q

- Don't use a guard uvar - we're only setting variables now, and
- that's basically free.
- Allow non-universal color variables
- Simplify the root color setting a bit.
- Some comments

This runs build_tools/style.fish, which runs clang-format on C++, fish_indent on fish and (new) black on python.
If anything is wrong with the formatting, we should fix the tools, but automated formatting is worth it.
No longer uses global vars to cache set_color output, this was
from before set_color was a builtin, it is pointless now.
This is also a prompt from before we had bright named colors,
and it appears it was relying on -o red to get bright red.
so use brred, etc.
