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.
Blergh
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.
