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.
These were hard to read in the browser, but not in the terminal.
The palette in color.cpp lists #000080 for blue, which is *even darker*. I'm not sure if that's actually a thing - I was under the impression that table was taken from xterm.
Either way, listing it in this color doesn't do anyone any favors. It's just a rough approximation anyway.
Otherwise this has filesystem order, which on my system is quite
chaotic.
An alternative would be to randomize the order so people see different
prompts each time.
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.
When `fish` is running in the Chrome OS Linux VM (Crostini),
both `help` and `fish_config` opened a "file not found"
page. That is because on Crostini, `BROWSER` is usually set to
`garcon-url-handler`, which opens URLs in the host OS Chrome
browser. That browser lacks access to the Linux file system.
This commit fixes these commands. `help` now opens the URL on
www.fishshell.com. `fish_config` now opens the URL for the
server it starts. Previously, it opened a local file that
redirects to the same URL.
In the case of `help`, the situation could be improved further
by starting a web server to serve help. I don't know of another
way to access `/share/fish` from outside the VM without user
intervention, and I think that might be a part of the security
model for the Crostini VM.
It's hard to write a test for this. I checked that `help math`,
`python2 webconfig.py`, and `python3 webconfig.py` work on my
machine running in Crostini.
* Ensure web_config works on WSL
web_config could sometimes fail on WSL if the user chose not to append
windows directories to their linux $PATH. This change ensures that the
cmd.exe executable is found in most cases even if windows directories
are not appended to $PATH on linux.
An error message letting the user know that cmd.exe was not found, and
that they should add the cmd.exe dir to their $PATH before running
fish_config is displayed if cmd.exe is still not found.
* Exit with a non 0 status code if cmd.exe is not found
This still showed the background gradient, which is just a waste and
looks weird.
Instead make the actual content fullscreen (except for the border
radius, for now)
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.
This had a classic float:left layout, which led to awkward gaps and
stuff.
Since what we want here is basically 100% exactly a flexbox, just use that.
Note: No flexbox for the prompts, atm, because having multiple of
those next to each other looks a bit weird.
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.
There's a macOS bug with Source Code Pro that makes it unable to be
colored. Since that makes webconfig unusable, stop recommending it.
Instead, we just pick the default monospace font for the system.
This is slated for removal in python 3.10, see
https://www.python.org/dev/peps/pep-0594/#cgi.
We currently only use it for three things:
- escape_html in old python versions that didn't have that in the html
module
- Parsing multipart/form-data
- Figuring out the charset for json
We keep the first one - if loading escape_html from html fails we fall
back to cgi.
We remove the second - I can't find any case where we use
multipart/form-data. Any place we post data we either explicitly pass
application/x-www-form-urlencoded or implicitly use application/json.
The third is the tricky bit. This drops charset detection under the
assumption that we're never going to encounter anything other than
utf-8 (or ascii, which is a utf-8 subset). I'm not sure that holds,
but if it doesn't we can just add a regex to parse the charset.
These used a different object format, so they were passed to
interpret_color wrong.
Because the "common" and "syntax" division doesn't really help all
that much, let's just flatten the thing.
See #7596.
And again clang-format does something I don't like:
- if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0) return found;
+ if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0)
+ return found;
I *know* this is a bit of a long line. I would still quite like having
no brace-less multi-line if *ever*. Either put the body on the same
line, or add braces.

Just copy that "find an executable" code we already have,
the one that was commented with "oh, btw, distutils.spawn.find_executable is bad",
and use it here as well.
Work towards #7514.
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.

The colors defined in `colorutils.js` are specified in
fish format, and therefore RGB values lack the leading
`#` character and do not fully follow the html/css spec
(w3.org/TR/css-color-4/#typedef-hex-color).
Web config sends these values as-is to the browser,
without first converting to a browser-friendly format.
While this (somehow) works for the most part, a few
colors get lost along the way and do not display in
the customization selector nor in the preview when
selected. This behavior was seen in Firefox.
To fix this, let's prepend the missing '#' character
to all RGB colors defined in `colorutils.js`.
This improves some generated completions, for example:
diff -u completions.old/g3topbm.fish completions.new/g3topbm.fish
+complete -c g3topbm -o stop_error -d 'This option tells g3topbm to fail when it finds a problem in the input'
-complete -c g3topbm -o stop_error
This used to use "success", which was our own thing, but which I can't
get working.
So instead we just use ".then", which only passes one object as an
argument that then contains all the other data we use.
This should be enough to complete the port to angular 1.8
Current firefox-developer-edition (i.e. the beta) blocks here.
This is awful and bad, but we can easily work around it by just using
a thread.

Fixes#7158
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 really kinda hate how insistent clang-format is to have line
breaks *IFF THE LINE IS TOO LONG*.
Like... lemme just add a break if it looks better, will you?
But it is the style at this time, so we shall tie an onion to our
belt.
* Fix manpath handling in create_manpage_completions.py
...as well as do some (very!) light cleanup.
Currently, `create_manpage_completions.py` does not properly
understand/respect the `$MANPATH` variable. One important feature of
`$MANPATH` is that an empty component (i.e. the trailing : in
`foo:bar:`) expands to the 'default' or 'system' path -- that is to say,
the path that would be used if `$MANPATH` was unset. This allows the
user to extend the manpath without clobbering it, and has been a feature
many Unices have included for years.
The current implementation blindly uses the `$MANPATH` variable if it
exists, which does not allow for this behaviour -- to expand the
variable correctly, an external program must be invoked. Therefore, we
first shell out to the 'proper' (read: best guess) external program. If
that fails, we can then try to use `$MANPATH` directly/literally.
Finally, if both of those are impossible, we can fall back to some
common paths from widely used operating systems.
Note that the `man.conf` parsing has been removed: this is because while
many 'traditional' Unices (BSDs, Solaris, macOS) support this file, only
macOS actually ships a file -- most other Unices use a `conf.d`-style
layout and supporting that from our Python is impractical and silly at
best. On GNU (read: Linux) systems, `mandb` uses `/etc/man_db.conf` with
slightly different syntax and sematics. As this code-path has bitrotted
(and likely never worked, anyway), just remove it.
`create_manpage_completions.py` looks like it has suffered a lot of
confusion and bitrot in general over the last few years -- and is
overdue for a major refactoring. I am quite interested in tackling this,
but I plan to wait until the go-ahead to drop support for Python 2 is
given, as a major refactor/rewrite that still supports Python 2 (and
thus ignores the ergonomic/API/syntax improvements of Python 3) does not
make sense to me.
Related: #5657
It would probably be good to revisit `man.fish` once again when a
comprehensive refactor happens: hopefully every permutation of
`man`/`$MANPATH` could be documented as part of that effort.
* Restore /etc/man.conf parsing
I was not aware that this codepath was used -- since it appeared that it
would throw an error when it was reached. Redo it, using regex, and
support parsing NetBSD man.conf as well (untested).
* Fix create_manpage_completions.py under Python 2
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.

Mostly line breaks, one instance of tabs!
For some reason clang-format insists on two spaces before a same-line comment?
(I continue to be unimpressed with super-strict line length limits,
but I continue to believe in automatic styling, so it is what it is)

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.
OpenBSD uses [unveil(2)](https://man.openbsd.org/unveil) in chromium and
firefox. This means that things outside of directories like ~/Downloads or /tmp are not visible to the
browsers.
Change webconfig so it uses tempfile.NamedTemporaryFile to create our temp file.
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

This mostly fixes some wrong indents or replaces some stray tab indents.
I excluded alignment on purpose, because we have a whole bunch of code
that goes like
```fish
complete -c foo -n 'some-condition' -l someoption
complete -c foo -n 'some-longer-condition' -l someotheroption
```
and changing it seems like a larger thing and would include more
thrashing.

Since the url is inside a AngularJS markup {{url}}, it's better to use **ng-href**.
From [AngularJS Documentation](https://docs.angularjs.org/api/ng/directive/ngHref):
<br>
"Using AngularJS markup like {{hash}} in an href attribute will make the link go to the wrong URL if the user clicks it before AngularJS has a chance to replace the {{hash}} markup with its value. Until AngularJS replaces the markup the link will be broken and will most likely return a 404 error. The ngHref directive solves this problem."
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.
This exposes it more, since it's quite an important function.
We should do the same with the other vcs functions.
We leave a compatibility shim in place for now.
Some $TERMs like tmux and linux use an sgr0 ("reset") value that ends
in \co instead of "m". We need to adjust our regex here to catch that,
or we'd miscount lines with it.
This broke when --preset was introduced.
We allow a "--preset" or "--user" to appear right after the "bind",
and save the value, but don't use it yet.

Starting with Fedora 30 and RHEL 8, ambiguous python shebangs will now
throw errors during the RPM build process instead of just warnings,
since these systems have moved to Python 3 by default, and Python 2 may
not be available in the future.

Drop these shebangs as the scripts are only ever called from fish
wrappers.
* Severely extended the sorin theme
This theme should now mostly match the original.
* Removed superfluous whitespace
* Inlined external links as ASCII art
* Made myself the author of the sorin theme
* Removed superfluous read delemiter
* Renamed __fish_git_action to fish_print_git_action
* Adde a minor comment
The solarized themes now define pager colors, while other schemes
don't.
So if a user picks one of them, and then another, they'd keep the
pager colors.
Instead, since the default theme is now complete, any theme that does
not define its own pager colors will always get the default ones.

Ideally we wouldn't have to duplicate this info, but I don't have a

- Remove use of `eval`
- Use `git rev-parse` instead of `git status` as its faster,
