|

### Reloading the candidate list
|
||||
|
||||
By binding `reload` action to a key or an event, you can make fzf dynamically
|
||||
reload the candidate list. See https://github.com/junegunn/fzf/issues/1750 for
|
||||
more details.
|
||||
|
||||
#### 1. Update the list of processes by pressing CTRL-R
|
||||
|
||||
```sh
|
||||
FZF_DEFAULT_COMMAND='ps -ef' \
|
||||
fzf --bind 'ctrl-r:reload($FZF_DEFAULT_COMMAND)' \
|
||||
--header 'Press CTRL-R to reload' --header-lines=1 \
|
||||
--height=50% --layout=reverse
|
||||
```
|
||||
|
||||
#### 2. Switch between sources by pressing CTRL-D or CTRL-F
|
||||
|
||||
```sh
|
||||
FZF_DEFAULT_COMMAND='find . -type f' \
|
||||
fzf --bind 'ctrl-d:reload(find . -type d),ctrl-f:reload($FZF_DEFAULT_COMMAND)' \
|
||||
--height=50% --layout=reverse
|
||||
```
|
||||
|
||||
#### 3. Interactive ripgrep integration
|
||||
|
||||
The following example uses fzf as the selector interface for ripgrep. We bound
|
||||
`reload` action to `change` event, so every time you type on fzf, ripgrep
|
||||
process will restart with the updated query string denoted by the placeholder
|
||||
expression `{q}`. Also, note that we used `--phony` option so that fzf doesn't
|
||||
perform any secondary filtering.
|
||||
|
||||
```sh
|
||||
INITIAL_QUERY=""
|
||||
RG_PREFIX="rg --column --line-number --no-heading --color=always --smart-case "
|
||||
FZF_DEFAULT_COMMAND="$RG_PREFIX '$INITIAL_QUERY'" \
|
||||
fzf --bind "change:reload:$RG_PREFIX {q} || true" \
|
||||
--ansi --phony --query "$INITIAL_QUERY" \
|
||||
--height=50% --layout=reverse
|
||||
```
|
||||
|
||||
If ripgrep doesn't find any matches, it will exit with a non-zero exit status,
|
||||
and fzf will warn you about it. To suppress the warning message, we added
|
||||
`|| true` to the command, so that it always exits with 0.
|
||||
|
||||
### Preview window
|
||||
|
||||
When the `--preview` option is set, fzf automatically starts an external process
