Find the last occurrence of the last character in the pattern and
perform the search algorithm only up to that point.
The effectiveness of this mechanism depends a lot on the shape of the
input and the pattern.
The environment variable get the value of the preview label, even if it
has been updated with an action. It can be useful to track the label of
the preview and be able to switch between previews using only one
binding.

This makes it possible to skip one of the above key bindings or
completions by setting a variable to an empty string. For example,
FZF_CTRL_T_COMMAND= FZF_ALT_C_COMMAND= \
eval "$(fzf --zsh)"

This simplifies the distribution, and the users are less likely to have
problems caused by using incompatible scripts and binaries.

fzf --fish | source
For those who prefer to manage default options in a file.
If the file is not found, fzf will exit with an error.
We're not setting a default value for it because:
1. it's hard to find a default value that can be universally agreed upon
2. to avoid fzf having to check for the existence of the file even when it's not used
* Use `--unicode-placeholder` for consistent result in and out of tmux
* Use updated version of junegunn/go-runewidth that handles diacritics
used in Kitty Unicode placeholder

fzf --preview 'imgcat -W $FZF_PREVIEW_COLUMNS -H $FZF_PREVIEW_LINES {}'
Notes:
* There is no good way to determine the height of the rendered image,
so we assume that the image takes the full height of the preview
window. So the image cannot be displayed with the other text.
* fzf-preview.sh script was updated to use `imgcat` if it's available
but `chafa` is not.
* iTerm2 also supports Sixel, so adding support for this protocol is not
quite necessary but it renders animated GIFs much better (e.g. looping).
Progress:
* Sixel image can now be displayed with other text, and is scrollable
* If an image can't be displayed entirely due to the scroll offset, fzf
will render a wireframe to indicate that an image should be displayed
* Renamed $FZF_PREVIEW_{WIDTH,HEIGHT} to $FZF_PREVIEW_PIXEL_{WIDTH,HEIGHT}
for clarity
* Added bin/fzf-preview.sh script to demonstrate how to display an image
using Kitty or Sixel protocol
An example:
ls *.jpg | fzf --preview='seq $((FZF_PREVIEW_LINES*9/10)); fzf-preview.sh {}; seq 100'
A known issue:
* If you reduce the size of the preview window, the image may extend
beyond the preview window
# Scrolling will behave similarly to CTRL-E and CTRL-Y of vim
fzf --bind scroll-up:offset-up,scroll-down:offset-down \
--bind ctrl-y:offset-up,ctrl-e:offset-down \
--scroll-off=5

* Works inside and outside of tmux
* There is a problem where fzf unnecessarily displays the scroll offset
indicator at the topbright of the screen when the image just fits the
preview window. This is because `kitty icat` generates an extra line
after the image area.
# A 5-row images; an extra row at the end confuses fzf

Can we find a better name? I have considered the followings.
* 'point', because "the pointer" points to the current item.
* 'shift', 'switch', 'move', etc. These are not technically correct
because the current item can change without cursor movement (--tac,
reload, search update)
* 'change' is already taken. 'change-current' feels a bit wordy and
sounds wrong, 'current-changed' is wordy and doesn't go well with the
other event names
* 'target', not straightforward

* Default border style on Windows is changed to `sharp` because some
Windows terminals are not capable of displaying `rounded` border
characters correctly.
* If your terminal emulator renders each box-drawing character with
2 columns, set `RUNEWIDTH_EASTASIAN` environment variable to `1`.
Even when {q} is empty. Because, why not?
While this can be seen as a breaking change, there is an easy workaround
to keep the old behavior.
# This will show // even when the query is empty
: | fzf --preview 'echo /{q}/'
# But if you don't want it,
: | fzf --preview '[ -n {q} ] || exit; echo /{q}/'
