tmux ends a command at an argument whose last character is ';', so a
--border-label ending in one was stored truncated. escapeTmuxSeparator
only covered a value that was exactly ';'.
fzf --popup --border-label 'foo;' -> @fzf-border-label was 'foo'
--border-label of a tmux floating pane was stored in the pane title and
read back by pane-border-format as '#{pane_title}', so any program in the
pane could replace the border text by setting the title. On Zellij the
name was only set when the pane was created. Either way the built-in
label actions could not touch it, as fzf draws no border of its own
there.
- tmux: hold the label in pane-scoped @fzf-border-label. Set the option
even without a label, so a later change-border-label has somewhere to
write. Drop select-pane -T; the pane title is left to the user
- Zellij: run 'zellij action rename-pane' on label change. 'zellij run'
has no option to set the environment of the new pane, so the command
exports the target itself
- change-border-label and transform-border-label now update the native
border, through the setter nativeLabelSetter picks by multiplexer
- The pane is named in a __FZF_INTERNAL_ variable that runProxy withholds
from the environment replay, so the same name in the outer environment
cannot redirect the update to another pane
Blocking run-shell suspends client key processing until the command
exits, so a floating pane deadlocks; popup input bypasses the suspended
path. Fall back to display-popup when TMUX_PANE is not set.
The native border is the handle for moving and resizing the pane with
the mouse, so use it by default, consistent with tmux. fzf draws its
own border only when a border style is explicitly specified with
--border. Extract the shared native-border decision into a helper.
The pane sets the options itself before running fzf, so that they are
in place no matter how quickly the command exits, targeted at
$TMUX_PANE; the default target would resolve to the active pane of
the session's current window.
- pane-border-format is set to '#{pane_title}' so that the label is
displayed on the border when pane-border-status is enabled;
pane-border-status itself is a window option in released tmux
versions and is left alone
- When a border style is explicitly specified with --border, a popup
is used instead of a floating pane so that the fzf-drawn border is
the only border shown; give 'border-native' to force a floating pane
- 'none' and 'line' are treated as no border; fzf draws no box for
either, so the label is displayed on the native border
- Remove 'border-fzf' which is now redundant; it was never released
- The title is escaped for select-pane -T which expands format
expressions; a lone ';' is escaped as tmux would treat it as a
command separator
- The label is skipped when ANSI stripping leaves an empty string
- --border-label-pos is ignored
- Fix remain-on-exit set on the original pane instead of the floating
pane
Unlike a popup, a floating pane is not modal; you can switch to other
panes and windows while fzf is running, move and resize the pane with
the mouse, zoom it to fullscreen, and use copy-mode in it.
- Floating pane always has a native border, so 'border-native' is
implied; give new 'border-fzf' option to fall back to a popup where
fzf draws its own border
- Popup is also used on tmux versions below 3.7, or when the window is
too small to fit a floating pane
- new-pane does not block until the command finishes and does not
propagate the exit status; block on a wait-for channel signaled by
the pane and pass the exit status through a temporary file
- Watchdog process signals the channel when the pane is closed
abnormally (e.g. kill-pane)
- Kill the pane when the proxy process is interrupted, like a popup
dying with its client
- Unzoom the window before creating the floating pane; doing so over a
zoomed window crashes the tmux server on 3.7b, and newer versions of
tmux unzoom the window anyway
- Floating pane size excludes the border and the position is that of
the content area; treat the requested size as the total footprint
including the border for consistency with popups
- Close the pane on exit even when remain-on-exit is on
- Pre-create the exit status file with O_EXCL to prevent tampering on
a shared TMPDIR
Options:
--footer=STR String to print as footer
--footer-border[=STYLE] Draw border around the footer section
[rounded|sharp|bold|block|thinblock|double|horizontal|vertical|
top|bottom|left|right|line|none] (default: line)
--footer-label=LABEL Label to print on the footer border
--footer-label-pos=COL Position of the footer label
[POSITIVE_INTEGER: columns from left|
NEGATIVE_INTEGER: columns from right][:bottom]
(default: 0 or center)
The default border type for footer is 'line', which draws a single
separator between the footer and the list. It changes its position
depending on `--layout`, so you don't have to manually switch between
'top' and 'bottom'
The 'line' style is now supported by other border types as well.
`--list-border` is the only exception.
This commit adds the `border-native` resulting in the following:
```
--tmux[=[center|top|bottom|left|right][,SIZE[%]][,SIZE[%]][,border-native]]
```
By default, when not specified, the `-B` flag is passed to the
`tmux popup-window` command such that no border is drawn around
the tmux popup window.
When the `border-native` option is present, the `-B` flag is omitted
and the popup window is drawn using the border style configured in
the tmux config file.
