0.46.0

• Added two new events
  • result - triggered when the filtering for the current query is complete and the result list is ready
  • resize - triggered when the terminal size is changed
• fzf now exports the following environment variables to the child processes

  Variable	Description
  FZF_LINES	Number of lines fzf takes up excluding padding and margin
  FZF_COLUMNS	Number of columns fzf takes up excluding padding and margin
  FZF_TOTAL_COUNT	Total number of items
  FZF_MATCH_COUNT	Number of matched items
  FZF_SELECT_COUNT	Number of selected items
  FZF_QUERY	Current query string
  FZF_PROMPT	Prompt string
  FZF_ACTION	The name of the last action performed

  • This allows you to write sophisticated transformations like so

    # Script to dynamically resize the preview window
    transformer='
      # 1 line for info, another for prompt, and 2 more lines for preview window border
      lines=$(( FZF_LINES - FZF_MATCH_COUNT - 4 ))
      if [[ $FZF_MATCH_COUNT -eq 0 ]]; then
        echo "change-preview-window:hidden"
      elif [[ $lines -gt 3 ]]; then
        echo "change-preview-window:$lines"
      elif [[ $FZF_PREVIEW_LINES -ne 3 ]]; then
        echo "change-preview-window:3"
      fi
    '
    seq 10000 | fzf --preview 'seq {} 10000' --preview-window up \
                    --bind "result:transform:$transformer" \
                    --bind "resize:transform:$transformer"

  • And we're phasing out {fzf:prompt} and {fzf:action}
• Changed mattn/go-runewidth dependency to rivo/uniseg for accurate results
  • Set --ambidouble if your terminal displays ambiguous width characters (e.g. box-drawing characters for borders) as 2 columns
  • RUNEWIDTH_EASTASIAN=1 is still respected for backward compatibility, but it's recommended that you use this new option instead
• Bug fixes
