+### Toggling with a single key binding
+
+The above example uses two different key bindings to toggle between two modes,
+but can we just use a single key binding?
+
+To make a key binding behave differently each time it is pressed, we need:
+
+1. a way to store the current state. i.e. "which mode are we in?"
+2. and a way to dynamically perform different actions depending on the state.
+
+The following example shows how to 1. store the current mode in the prompt
+string, 2. and use this information (`{fzf:prompt}`) to determine which
+actions to perform using the `transform` action.
+
+```sh
+fd --type file |
+  fzf --prompt 'Files> ' \
+      --header 'CTRL-T: Switch between Files/Directories' \
+      --bind 'ctrl-t:transform:[[ ! {fzf:prompt} =~ Files ]] &&
+              echo "change-prompt(Files> )+reload(fd --type file)" ||
+              echo "change-prompt(Directories> )+reload(fd --type directory)"' \
+      --preview '[[ {fzf:prompt} =~ Files ]] && bat --color=always {} || tree -C {}'
+```

 CHANGELOG
 =========

+0.45.0
+------
+- Added `transform` action to conditionally perform a series of actions
+  ```sh
+  # Disallow selecting an empty line
+  echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
+    fzf --height '~100%' --reverse --header 'Select one' \
+        --bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"'
+
+  # Move cursor past the empty line
+  echo -e "1. Hello\n2. Goodbye\n\n3. Exit" |
+    fzf --height '~100%' --reverse --header 'Select one' \
+        --bind 'enter:transform:[[ -n {} ]] && echo accept || echo "change-header:Invalid selection"' \
+        --bind 'focus:transform:[[ -n {} ]] && exit; [[ {fzf:action} =~ up$ ]] && echo up || echo down'
+
+  # A single key binding to toggle between modes
+  fd --type file |
+    fzf --prompt 'Files> ' \
+        --header 'CTRL-T: Switch between Files/Directories' \
+        --bind 'ctrl-t:transform:[[ ! {fzf:prompt} =~ Files ]] &&
+                  echo "change-prompt(Files> )+reload(fd --type file)" ||
+                  echo "change-prompt(Directories> )+reload(fd --type directory)"'
+  ```
+- Added placeholder expressions
+    - `{fzf:action}` - The name of the last action performed
+    - `{fzf:prompt}` - Prompt string (including ANSI color codes)
+    - `{fzf:query}` - Synonym for `{q}`
+- Added support for negative height
+  ```sh
+  # Terminal height minus 1, so you can still see the command line
+  fzf --height=-1
+  ```
+  - This handles a terminal resize better than `--height=$(($(tput lines) - 1))`
+- Added `accept-or-print-query` action that acts like `accept` but prints the
+  current query when there's no match for the query
+  ```sh
+  # You can make CTRL-R paste the current query when there's no match
+  export FZF_CTRL_R_OPTS='--bind enter:accept-or-print-query'
+  ```
+  - Note that there are alternative ways to implement the same strategy
+    ```sh
+    # 'become' is apparently more versatile but it's not available on Windows.
+    export FZF_CTRL_R_OPTS='--bind "enter:become:if [ -z {} ]; then echo {q}; else echo {}; fi"'
+
+    # Using the new 'transform' action
+    export FZF_CTRL_R_OPTS='--bind "enter:transform:[ -z {} ] && echo print-query || echo accept"'
+    ```
+- Added `show-header` and `hide-header` actions
+- Bug fixes
+
+0.44.1
+------
+- Fixed crash when preview window is hidden on `focus` event
+
+0.44.0
+------
+- (Experimental) Sixel image support in preview window (not available on Windows)
+    - [bin/fzf-preview.sh](bin/fzf-preview.sh) is added to demonstrate how to
+      display an image using Kitty image protocol or Sixel. You can use it
+      like so:
+      ```sh
+      fzf --preview='fzf-preview.sh {}'
+      ```
+- (Experimental) iTerm2 inline image protocol support in preview window (not available on Windows)
+  ```sh
+  # Using https://iterm2.com/utilities/imgcat
+  fzf --preview 'imgcat -W $FZF_PREVIEW_COLUMNS -H $FZF_PREVIEW_LINES {}'
+  ```
+- HTTP server can be configured to accept remote connections
+  ```sh
+  # FZF_API_KEY is required for a non-localhost listen address
+  export FZF_API_KEY="$(head -c 32 /dev/urandom | base64)"
+  fzf --listen 0.0.0.0:6266
+  ```
+    - To allow remote process execution, use `--listen-unsafe` instead
+      (`execute*`, `reload*`, `become`, `preview`, `change-preview`, `transform-*`)
+      ```sh
+      fzf --listen-unsafe 0.0.0.0:6266
+      ```
+- Bug fixes
+
 0.43.0
 ------
 - (Experimental) Added support for Kitty image protocol in the preview window
+  (not available on Windows)
  ```sh
  fzf --preview='
    if file --mime-type {} | grep -qF image/; then

So the image cannot be displayed with the other text. * fzf-preview.sh script was updated to use `imgcat` if it's available but `chafa` is not. * iTerm2 also supports Sixel, so adding support for this protocol is not quite necessary but it renders animated GIFs much better (e.g. looping).	2023-11-07 11:51:21 +09:00
