fish_git_prompt encloses its output in brackets, however this can be changed by supplying a format string to it, i.e. `fish_git_prompt %s`.
However when using `fish_vcs_prompt` there's no way to pass on the arg to fish_git_prompt, so you need to manually remove it.
fish_hg_prompt doesn't have the same format string support as fish_git_prompt, but I suppose it could be added later if needed.
When sending SIGCONT to a stopped job, this behaves now
a bit more like a job that was continued by the bg builtin;
bg uses job_t::continue_job which seems overkill here.
We don't need to call it if a job was stopped, because in that case
read_i() will fire fish_prompt already, because the newly stopped job
was probably a foreground job.
Fixes#1018
This just produced a spurious "Unknown signal" error on NetBSD and OpenBSD, and
the number picked was arbitrary. So let's just use the maximum that
appears to work everywhere.
(I will hate this if I test it elsewhere and need to reduce it to 62)
(This is a squashed commit, I did indeed hate it when I moved from
NetBSD to OpenBSD)
The default implementation will not print any output in that case, but this provides users with additional flexibility when it comes to customising the shell's behaviour.
This allows users to customise the behaviour of the shell by redefining the function. This is similar to how fish_title or fish_greeting behave, where the default implementation can be easily overridden.
The function receives as arguments the job id, command line, signal name and signal description.
Since 4414d5c888 (in fish 3.0.0) we
don't autoload completions if the command doesn't exist.
So there is no need to check inside the scripts anymore.
Whats more, a few (like pip and cabal) checked `command -q` instead of
`type -q`, meaning they'd fail if someone used a function instead of a
command of that name.
If the *command* actually needs to exist, checks like that are still
warranted, like in `npm` where aliasing it to `nvm` is popular.
A teensy additional bit: Make `sysctl -w` the same as `sysctl
--write`. That description was bogus.
At the moment calling __fish_prepend_sudo multiple times does not toggle
sudo, and also unnecessarily uses the `-c` flag to `commandline` to see if
the first token on the commandline is "sudo".
This change removes the `-c` switch and also toggles "sudo" on multiple
calls to __fish_prepend_sudo, while maintaining the cursor position and
while maintaining any spaces between "sudo" and the next token on the
commandline.
The local-exported variable will have disappeared by the time the
function is called.
"-V"/"--inherit-variable" is meant for something like this.
Fixes#7011
This allows tools like `stty` to set the terminal modes and fish will
honor them, for external commands.
The modes for fish are kept as they are.
Until now, the only change fish would do to the external modes is to
disable flow control *every time*, this changes it to only disabling
it on startup.
After that we don't apply *any* changes to the external modes (no
checks or validation or...), because we've never done that (other than
flow control), and it's not been a problem.
Fixes#2315.
