As mentioned in 04c913427 (Limit command line rendering to $LINES
lines, 2024-10-25) our rendering breaks when the command line overflows
the screen and we have a pager search field.
Let's also apply the overflow logic in this case.
Note that the search field still works, it's just not visible.
In future we should maybe show a small search field (~4 lines) in
this case (removing 4 screen lines worth of command line). But again,
this is not really important.
If the first physical line in the command line overflows the screen,
the cursor will be wrong and we'll fail to clear the prompt without
a manual ctrl-l. Let's fix that, and also don't print the OSC 133
marker in this case.
Currently, when we are scrolled, the first line on the screen still
gets an indentation that would normally be filled by the prompt.
This happens even for soft-wrapped lines, so they might be
torn apart in weird ways here.
In future, we might paint the prompt here. If not, the current
behavior for soft-wrapped lines is debatable but its' not super
important to fix. The main goal is to first get rid of glitches in
these edge cases.
This test does "isolated-tmux send-keys Escape" to exit copy mode. When
EDITOR contains "vi", tmux will use Vi keybindings where Escape does
something else ("q" would exit copy mode).
Tests want to have predictable behavior so let's declare the default
emacs key bindings unconditionally.
Fixes#10812
This added link args to target macOS 10.9, but these arguments are not necessary
when building via the make_pkg.sh script, and this file is causing other
problems.
Let's provide a sensible default here. Use a line for "insert" and an
underline for "replace_one" mode. Neovim does the same, it feels pretty
slick.
As mentioned in #10806
As of the parent commit, __fish_vi_key_bindings_remove_handlers
should be working properly now, so this is no longer necessary That
function also cleans up other stuff like fish_cursor_end_mode, that
fish_default_key_bindings doesn't know anything about.
Also this fixes a spurious exit status of 4 in some scenarios.
fish_key_bindings may be set directly
or via fish_{default,vi}_key_bindings.
The latter use "set --no-event" to simplify their control
flow. This (24836f965 (Use set --no-event in the key binding
functions, 2023-01-10)) broke Vi mode cleanup, since Vi mode
uses a variable hook. Let's update this variable also when using
fish_{default,vi}_key_bindings. Another reason to keep this variable
in sync is to make the fish_key_bindings handlers working as expected.
Render the command line buffer only until the last line we can fit
on the screen.
If the cursor pushes the viewport such that neither the prompt nor
the first line of the command line buffer are visible, then we are
"scrolled". In this case we need to make sure to erase any leftover
prompt, so add a hack to disable the "shared_prefix" optimization
that tries to minimize redraws.
Down-arrow scrolls down only when on the last line, and up-arrow always
scrolls up as much as possible. This is somewhat unconventional;
probably we should change the up-arrow behavior but I guess it's a
good idea to show the prompt whenever possible. In future we could
solve that in a different way: we could keep the prompt visible even
if we're scrolled. This would work well because at least the left
prompt lives in a different column from the command line buffer.
However this assumption breaks when the first line in the command
line buffer is soft-wrapped, so keep this approach for now.
Note that we're still broken when complete-and-search or history-pager
try to draw a pager on top of an overfull screen. Will try to fix
this later.
Closes#7296
It's a 9-char CSI and we've read 3 (`<ESC>[T`), so we need to read six more.
Verified against the previous C++ codebase and couldn't find a reason for the
change to consuming 10 chars in a `git blame` run.
Commit ba67d20b7 (Refresh TTY timestamps after nextd/prevd, 2024-10-13)
wasn't quite right because it also needs to fix it for arbitrary commands.
While at it, do this only when needed:
1. It seems to be only relevant for multiline prompts.
Note that we can wait until after evaluation to check if the prompt is
multiline, because repaint events go through the queue, see 5ba21cd29
(Send repaint requests through the input queue again, 2024-04-19).
2. When the binding doesn't execute any external command, we probably don't
need to fix up whatever the user printed. If they actually wanted to show
output and print another prompt, they should currently use "__fish_echo",
to properly support multiline prompts. Bindings should produce no other
output. What distinguishes external programs is that they can trigger this
issue even if they don't produce any output that remains visible in fish,
namely by using the terminal's alternate screen.
Would be nice if we could get rid of __fish_echo; I'm not yet sure how.
Fixes#10800
A side effect of cd9e50c2c (completions/set: Complete variables of all scopes
when setting, 2024-10-03) is that
HOME=$(mktemp -d) fish
fish_config choose ayu\ Light
set -S fish_color_
gives only completions that have the "Universal variable" description even
though most colors are also defined in the global scope which usually takes
precedence.
Fix this by reordering the completions. (The last-added completion is shown
first which is very surprising, we should change that).
This is not perfect; if the user has already specified `-U`, then we should
probably not show description of the global version. But that's still
worth the trade that this commit makes. Finally, the description could show
something like "Defined in universal and global scope" etc.
The test case shows that the pager rendering is not quite right. It renders
'{\', leaving out the newline. This rendering is ambiguous.
Let's fix it by rendering \n as control picture, like we do for other control
characters in the pager.
Given
$ echo {\
C
where C is the cursor.
Completions have prefix "{\\\n".
Since \n has a wcwidth of -1, this line always fails
let prefix_len = usize::try_from(fish_wcswidth(&self.prefix));
This triggers uncovers a regression in 43e2d7b48 (Port pager.cpp, 2023-12-02),
where we end up computing comp_width=0 for all completions.
Fix this. Test in the next commit.
The C++ version added the prefix width only if the completion had a valid
width. That seems wrong, let's do it always (if the prefix width is valid).
Completion on ": {*," used to work but nowadays our attempt to wildcard-expand
it fails with a syntax error and we do nothing. This behavior probably only
makes sense for the overflow case, so do that.
On a German keyboard, with a German keymap, and this ~/.wezterm.lua
local wezterm = require 'wezterm'
local config = wezterm.config_builder()
config.enable_kitty_keyboard = true
return config
when I press shift+# (which is single quote)
WezTerm sends the CSI u encoding shift-'.
Because of this, we completely disable kitty progressive enhancements and
modifyOtherKeys on WezTerm.
It makes no sense for every single app to work around WezTerm violating the
protocol. All these workarounds just create unnecessary version dependencies.
Also our workaround is brittle; it breaks as soon as you're inside something
like SSH.
Least importantly, the workarond prevents users of English keyboard layouts
to easily use the new features.
Since it seems so easy to work around by settting "enable_kitty_keyboard = false",
and most importantly, since that's the default, it seems better to remove
the workaround to simplify the world.

This makes the default colorscheme less colorful for two reasons:
1. It makes it a little less "angry fruit salad"
2. Some terminals (like Microsoft's Windows Terminal) have a terrible
blue default that contrasts badly against a black background
The alternative is to make *parameters* "normal" and give commands the
current parameter color (cyan). But I've seen cyan be quite blue and
quite green depending on the terminal, so I don't want to rely on it.
`cargo build --git` clones a git repo without any tags, so you get a
version like
```
fish, version f3fc743fc
```
which is *just* the commit hash and missing the "3.7.1-NUM-g" part.
So, if we hit that case (detected because it has no ".", under the
assumption that we'll never make a version that's just "4" instead of
"4.0"), we prepend the version from Cargo.toml.
