fish_indent [OPTIONS] [FILE...]


fish_indent is used to indent a piece of fish code. fish_indent reads commands from standard input or the given filenames and outputs them to standard output or a specified file (if -w is given).

The following options are available:

  • -w or --write indents a specified file and immediately writes to that file.
  • -i or --no-indent do not indent commands; only reformat to one job per line.
  • -v or --version displays the current fish version and then exits.
  • --ansi colorizes the output using ANSI escape sequences, appropriate for the current $TERM, using the colors defined in the environment (such as $fish_color_command).
  • --html outputs HTML, which supports syntax highlighting if the appropriate CSS is defined. The CSS class names are the same as the variable names, such as fish_color_command.
  • -d or --debug=CATEGORY_GLOB enables debug output and specifies a glob for matching debug categories (like fish -d). Defaults to empty.
  • -D or --debug-stack-frames=DEBUG_LEVEL specify how many stack frames to display when debug messages are written. The default is zero. A value of 3 or 4 is usually sufficient to gain insight into how a given debug call was reached but you can specify a value up to 128.
  • --dump-parse-tree dumps information about the parsed statements to stderr. This is likely to be of interest only to people working on the fish source code.
