Close#1102
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).
So that it can determine if it should subtract 1 from $FZF_PREVIEW_LINES
to avoid scrolling issue of Sixel image that touches the bottom of the
screen.
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
* fix: turn off remain-on-exit only on fzf-tmux pane
Using `fzf-tmux` overwrites `remain-on-exit` for all panes in a window,
if it is only set globally or at a higher scope than window.
set-option -wg remain-on-exit on
set-option -s remain-on-exit on
This makes other panes in that window close immediately on exit after
using `fzf-tmux`, even though I expect them to remain open.
Since TMux 3.0, `remain-on-exit` is a pane option that can be set via
`set-option -p`. This will limit the option's scope to just the
`fzf-tmux` pane, thus allowing us to close it immediately without
overriding `remain-on-exit` on other panes in the window.

* fix: turn off synchronize-panes only on fzf-tmux pane
Similar reason to 482fd2b (fix: turn off remain-on-exit only on fzf-tmux
pane, 2023-08-24).
Limit scope on which option is set to bare minimum.
Have confirmed this will not feed input back to other panes which are
set to be synchronized. However, note that this will not stop `fzf-tmux`
from being launched by two synchronized panes in parallel.

Since we don't know in advance which flags tmux will support, simply
allow a single uppercase character ([A-Z]) for now.
fzf-tmux -xR -yS
fzf-tmux -x R -y S
Fix#1956
Requires latest tmux built from source (e.g. brew install tmux --HEAD)
Examples:
# 50%/50% width and height on the center of the screen
fzf-tmux -p
# 80%/80%
fzf-tmux -p80%
# 80%/40%
fzf-tmux -p80%,40%
# Separate -w and -h
fzf-tmux -w80% -h40%
# 80%/40% at position (0, 0)
fzf-tmux -w80% -h40% -x0 -y0
You can configure key bindings and fuzzy completion to open in tmux
popup window like so:
FZF_TMUX_OPTS='-p 80%'
fzf-tmux temporarily turns off remain-on-exit and synchronize-panes
options. We don't have to try to restore the values of the options if
they were already turned off when fzf-tmux was started.
