--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
For two ASCII characters, rows 0 and 1 of the score matrix collapse to
scalar running state, so Phase 2 and Phase 3 fuse into one pass with no
score arrays. withPos stores the two rows for the backtrace. Up to 1.4x
on two-char queries, the most common multi-char length.
Verify both fast paths against the general algorithm with exhaustive
(every short string over a class-complete alphabet) and fuzz tests,
runnable via the new make fuzz target.
Precompute OR of all sort keys; a byte position that is zero across every
key contributes a no-op pass. Default two-criteria setup leaves the low 32
bits zero, so 4 of 8 passes are skipped without a histogram scan. 2x on the
sort, 3-8% on high-match queries. No regression when all bytes are used.
Decision must not depend on threshold chain resolution
(computePreviewSize consults noSeparatorLine); separator is hidden only
when every spec in the chain displays a 'next' preview window with a
border line facing the input section. Otherwise err on the side of
showing it.
- Without active previewer, preview position is resolved from first spec
alone, so 'next' in a threshold alternative does not create input
window and cannot hide the separator
- Empty preview command is undecidable; preview(...) action can display
ad-hoc window at 'next' position at any time
- change-preview-window relayouts or repaints when separator visibility
changes even if the active spec is unchanged, without dropping preview
window forced by preview(...) action
Visible input border suppressed separator even when it draws no line
toward list section (bottom in default layout, top in reverse, vertical).
Suppress only when input border has a line on the list side; otherwise
fall through to adjacent section check.
- Requires header window to have content before treating it as facing
section; hasHeaderWindow returns true with empty header when input
border is visible
- Extract inputBorderFacesList and resolveInputBorderShape shared by
options and terminal
- Add tests for separator suppression rules
- Applies when adjacent section (header, header lines, or list) draws
border line facing input section
# No separator below header border
fzf --style full --input-border none --header foo
# Separator shown; nothing separates input from list
fzf --style full --input-border none --header foo --no-header-border
- Evaluated dynamically so change-header/toggle-header update it
- Inline header is drawn inside list border and not adjacent to input;
decide from section actually next to it
- Separator is kept when a preview window can be at 'next' position,
right next to the input section
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
Blocks execution of subsequent actions until the current search
completes, so motion actions operate on the complete result set.
# Move to the best match only after the search is done
fzf --bind 'start:change-query(foo)+wait+best'
- Blocks when a search is in progress, will be triggered by preceding
actions, or the query was edited in the same binding; no-op otherwise
- Initial input load counts as a search in progress, so 'start:wait'
blocks until the input is fully loaded and searched
- User input ignored while blocked, including --expect keys; keys bound
to abort/cancel cancel the wait and discard pending actions instead
- Actions deferred by the wait survive across nested lists (trigger
chords) and cancel/re-arm chains
- Debounced feedback after 200ms: dimmed prompt, hidden cursor, and
(..) on the info line
- Fires like result, but only after the input stream closes
- Use for one-shot per-query actions that would otherwise re-fire on
every intermediate snapshot during loading

Places preview adjacent to input on the list side: above input in the
default layout, below it in --layout=reverse.
fzf --preview 'cat {}' --preview-window=next
Close#4798
- every(N) fires every N seconds (fractional, floored to 0.01s)
- Encoded as tui.Every with duration in Char as milliseconds, so
every(1) and every(2) coexist as distinct keymap entries
- FZF_IDLE_TIME exposes whole seconds since the last user activity
(keystroke or mouse event); pair with every() for idle-based
patterns like auto-accept/auto-quit
Close#1211
toggle-preview-wrap (and -wrap-word) modifies t.activePreviewOpts.wrap,
but change-preview-window resets t.previewOpts to t.initialPreviewOpts,
discarding the user's toggle. Carry wrap and wrapWord over so toggles
survive a layout change. Explicit wrap / nowrap tokens in the new spec
still win, so cycling and the empty-token reset are unaffected.
Close#4791
New --border=dashed / --list-border=dashed / --header-border=dashed etc.
Uses U+2576 (╶) for horizontal edges and U+2506 (┆) for verticals, with
rounded corners (╭╮╰╯) and sharp T-junction mids (├┤). Terminal cells
are taller than wide (~2:1), so horizontals use a sparse stub per cell
while verticals need more dashes per cell to look evenly dashed.
Works with inline sections.
New BorderShape that embeds the section inside the --list-border
frame, joined to the list content by a horizontal separator with
T-junctions where the list shape has side borders. Requires a list
border with both top and bottom segments; falls back to 'line'
otherwise. Stacks when multiple sections are inline.
Sections inherit --color list-border by default and are colored as a
uniform block via their own --color *-border and *-bg.
Incompatible with --header-first. --header-border=inline requires
--header-lines-border to be inline or unset.
- Changed +m to --multi to enable multi-select in CTRL-R
- Changed exclude to exclude-multi and {1} to {+1} so
shift-delete removes all selected entries at once
When --walker=follow is used, symlinks like Wine's z: -> / cause fzf to
traverse the entire root filesystem. fastwalk's built-in loop detection
only catches this on the second pass, but a single pass through / already
causes severe CPU and memory exhaustion.
This fix resolves each symlink-to-directory target to its absolute real
path and skips it if it is an ancestor of (or equal to) the walker root.
Close#4710
When --walker=follow is used, symlink following is now handled by
fastwalk's IgnoreDuplicateDirs adapter which tracks visited directories
by device+inode. This prevents the same directory from being entered
more than once, avoiding effectively infinite traversal when a symlink
points outside the walker root.
Close#4710
Separate item identity from cursor tracking:
- Add --id-nth=NTH to define item identity fields for cross-reload ops
- --track reverts to a simple boolean flag
- track-current action no longer accepts nth argument
- With --multi, selections are preserved across reload-sync by matching
identity keys in the reloaded list
Close#4718Close#4701Close#4483Close#4409Close#3460Close#2441
Allow --track to accept an optional nth expression for cross-reload
tracking. When a reload is triggered, fzf extracts a tracking key from
the current item using the nth expression, blocks the UI, and searches
for a matching item in the reloaded list.
- --track=.. tracks by entire line, --track=1 by first field, etc.
- --track without NTH retains existing index-based behavior
- UI is blocked during search (dimmed query, hidden cursor, +T*/+t*)
- reload unblocks eagerly on match; reload-sync waits for stream end
- Escape/Ctrl-C cancels blocked state without quitting
- track-current action accepts optional nth: track-current(1)
- Validate nth expression at parse time for both --track and track()
- Cache trackKeyFor results per item to avoid redundant computation
- Rename executeRegexp to argActionRegexp

Use go-shellwords instead of strings.Fields to parse --with-shell,
so paths with spaces can be properly quoted.
ln -s /bin/bash "/tmp/ba sh"
fzf --with-shell='/tmp/ba\ sh -c' --preview 'echo hello world'
fzf --with-shell='"/tmp/ba sh" -c' --preview 'echo hello world'
