junegunn/fzf 0.46.0 on GitHub

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
