Unfortunately on Debian "open" is a symlink to "openvt", and there's
no way from outside to tell.
This prevents fish from failing because no browser could be found.
Today fish_cursor_selection_mode controls whether selection mode includes
the cursor. Since it's by default only used for Vi mode, perhaps use it to
also decide whether it should be allowed to select one-past the last character.
Not allowing to select to select one-past the last character is much nicer
in Vi mode. Unfortunately Vi mode sometimes needs to temporarily select
past end (using forward-single-char and such), so reset fish_cursor_selection_mode
for the duration of the binding.
Also fix other things like cursor placement after yank/yank-pop.

We have
bind --preset -M $mode --sets-mode paste \e\[200~ __fish_start_bracketed_paste
Commit c3cd68dda (Process shell commands from bindings like regular char
events, 2024-03-02) made it so __fish_start_bracketed_paste is no longer
executed before the bind mode is updated.
This is a long-awaited fix but it broke __fish_start_bracketed_paste's
assumption that $fish_bind_mode is the mode before we entered paste mode.
This means we never exit paste mode.
Work around that. I forgot about this issue because I already replaced our
bracketed paste handling on my fork.
Today,
bind foo "commandline -f expand-abbr; commandline -i \n"
does not work because this
1. enqueues an expand-abbr readline event
2. "commandline -i" inserts \n
3. processes the expand-abbr readline event
Since there is no abbreviation on the new line, this doesn't do anything.
PR https://github.com/fish-shell/fish-shell/pull/9398 would fix this
particular instance however it does not fix the issue that "commandline -i"
is run before the expand-abbr is processed by the reader. This is harmless
here but there would be a problem if "commandline" tried to read commandline
state that was created by a preceding command.
It's not super clear to me whether the above binding should work as one
would naively expect. That would imply that "commandline" would need to
drain all input events (at least all synthetic ones) from the input queue,
to ensure it sees the current state.
Fortunately the parent commit makes it so if we separate them
bind foo "commandline -f expand-abbr" "commandline -i \n"
both will be separate events and the commandline state will be synced after
each of them. This fixes abbreviation expansion here.
Also, we can now mix readline cmds and shell commands, which makes it shorter.
Most chat programs I found use Shift+Return to insert a newline while plain
Return sends the message. One user reported having only tried Shift+Return
and not knowing about Alt+Return.
No release notes yet because this only works on a very small number of
terminals. Once we enable CSI u, this should work on most modern terminals.
Unless the editor changed to a different file for some reason.
Note that the Kakoune integration uses -always to export the cursor even if
the user temporarily suppressed hooks - possibly a "fish_indent" hook.
One of the things that keep me from using Vi mode is that it doesn't define an
insert-mode shortcut to accept autosuggestions. Let's use Control-N because
that Vim key is the closest equivalent.
Closes#10339
... even if the file hasn't changed. This addresses an oddity in the following
case:
* Shell is started,
* function `foo` is sourced from foo.fish
* foo.fish is *externally* edited and saved
* <Loaded definition of `foo` is now stale, but fish is unaware>
* `funced foo` loads `type -p foo` showing changed definition, user exits
$EDITOR saving no changes (or with $status 0, more generally).
* Stale definition of `foo` remains
If a hostname starts with a dash `-` character, the prompt_hostname function
fails because the `string` function interprets it as an option instead
of an argument.
Inserting Tab or Backspace characters causes weird glitches. Sometimes it's
useful to paste tabs as part of a code block.
Render tabs as "␉" and so on for other ASCII control characters, see
https://unicode-table.com/en/blocks/control-pictures/. This fixes the
width-related glitches.
You can see it in action by inserting some control characters into the
command line:
set chars
for x in (seq 1 0x1F)
set -a chars (printf "%02x\\\\x%02x" $x $x)
end
eval set chars $chars
commandline -i "echo '" $chars
Fixes#6923Fixes#5274Closes#7295
We could extend this approach to display a fallback symbol for every unknown
nonprintable character, not just ASCII control characters.
In future we might want to support tab properly.
Fish functions are great for configuring fish but they don't integrate
seamlessly with the rest of the system. For tasks that can run outside fish,
writing scripts is the natural approach.
To edit my scripts I frequently run
$EDITOR (which my-script)
Would be great to reduce the amount typing for this common case (the names
of editor and scripts are usually short, so that's a lot of typing spent on
the boring part).
Our Alt+o binding opens the file at the cursor in a pager. When the cursor
is in command position, it doesn't do anything (unless the command is actually
a valid file path). Let's make it open the resolved file path in an editor.
In future, we should teach this binding to delegate to "funced" upon seeing
a function instead of a script. I didn't do it yet because funced prints
messages, so it will mess with the commandline rendering if used from
a binding. (The fact that funced encourages overwriting functions that
ship with fish is worrysome. Also I'm not sure why funced doesn't open the
function's source file directly (if not sourced from stdin). Persisting the
function should probably be the default.)
Alternative approach: I think other shells expand "=my-script" to
"/path/to/my-script". That is certainly an option -- if we do that we'd want
to teach fish to complete command names after "=". Since I don't remember
scenarios where I care about the full path of a script beyond opening it in
my editor, I didn't look further into this.
Closes#10266
gpg's --use-embedded-filename is a dangerous option that can cause gpg
to write arbitrary content to arbitrary files.
According to the GnuPG maintainer, this is not an option recommended
for use (https://dev.gnupg.org/T4500). Fish shouldn't encourage users
to supply it.
I've offered https://dev.gnupg.org/T6972 to upstream to make it even
more clear that this option is a bad idea.
While removing it, we might as well also remove
--no-use-embedded-filename, since it is effectively a no-op.
Instead of skipping for non-interactive shells, skip when stdin is not a tty.
This allows the cursor to be set for scripts that use the `read` command.
* Update just.fish to handle descriptions for completions
This change updates fish completions to also include descriptions for justfile recipes. It has been tested with descriptions for recipes with arguments as well
* rely on fish only (avoid sed)
