CHANGELOG
=========
0.19.0
------
- Added "reload" action for dynamically updating the input list without
restarting fzf. See https://github.com/junegunn/fzf/issues/1750 to learn
more about it.
```sh
# Using fzf as the selector interface for ripgrep
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
INITIAL_QUERY="foo"
FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \
fzf --bind "change:reload:$RG_PREFIX {q} || true" \
--ansi --phony --query "$INITIAL_QUERY"
```
- `--multi` now takes an optional integer argument which indicates the maximum
number of items that can be selected
```sh
seq 100 | fzf --multi 3 --reverse --height 50%
```
- If a placeholder expression for `--preview` and `execute` action (and the
new `reload` action) contains `f` flag, it is replaced to the
path of a temporary file that holds the evaluated list. This is useful
when you multi-select a large number of items and the length of the
evaluated string may exceed [`ARG_MAX`][argmax].
```sh
# Press CTRL-A to select 100K items and see the sum of all the numbers
seq 100000 | fzf --multi --bind ctrl-a:select-all \
--preview "awk '{sum+=\$1} END {print sum}' {+f}"
```
- `deselect-all` no longer deselects unmatched items. It is now consistent
with `select-all` and `toggle-all` in that it only affects matched items.
- Due to the limitation of bash, fuzzy completion is enabled by default for
a fixed set of commands. A helper function for easily setting up fuzzy
completion for any command is now provided.
```sh
# usage: _fzf_setup_completion path|dir COMMANDS...
_fzf_setup_completion path git kubectl
```
- Info line style can be changed by `--info=STYLE`
- `--info=default`
- `--info=inline` (same as old `--inline-info`)
- `--info=hidden`
- Preview window border can be disabled by adding `noborder` to
`--preview-window`.
- When you transform the input with `--with-nth`, the trailing white spaces
are removed.
- `ctrl-\`, `ctrl-]`, `ctrl-^`, and `ctrl-/` can now be used with `--bind`
- See https://github.com/junegunn/fzf/milestone/15?closed=1 for more details

expression is \fBKEY:ACTION\fR or \fBEVENT:ACTION\fR.
