=========
|
||||
|
||||
0.39.1
|
||||
0.40.0
|
||||
------
|
||||
- Added `toggle-track` action. Temporarily enabling tracking is useful when
|
||||
you want to see the surrounding items by deleting the query string.
|
||||
```sh
|
||||
export FZF_CTRL_R_OPTS="
|
||||
--preview 'echo {}' --preview-window up:3:hidden:wrap
|
||||
--bind 'ctrl-/:toggle-preview'
|
||||
--bind 'ctrl-t:toggle-track'
|
||||
--bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort'
|
||||
--color header:italic
|
||||
--header 'Press CTRL-Y to copy command into clipboard'"
|
||||
```
|
||||
- New actions
|
||||
- Added `change-header(...)`
|
||||
- Added `transform-header(...)`
|
||||
- Added `toggle-track` action. Temporarily enabling tracking is useful when
|
||||
you want to see the surrounding items by deleting the query string.
|
||||
```sh
|
||||
export FZF_CTRL_R_OPTS="
|
||||
--preview 'echo {}' --preview-window up:3:hidden:wrap
|
||||
--bind 'ctrl-/:toggle-preview'
|
||||
--bind 'ctrl-t:toggle-track'
|
||||
--bind 'ctrl-y:execute-silent(echo -n {2..} | pbcopy)+abort'
|
||||
--color header:italic
|
||||
--header 'Press CTRL-Y to copy command into clipboard'"
|
||||
```
|
||||
- Fixed `--track` behavior when used with `--tac`
|
||||
- However, using `--track` with `--tac` is not recommended. The resulting
|
||||
behavior can be very confusing.
