# fish_indent - indenter and prettifier

## Synopsis

    fish_indent [OPTIONS] [FILE ...]

## Description

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.

--only-indent

  Do not reformat, only indent each line.

--only-unindent

  Do not reformat, only unindent each line.

-c or --check

  Do not indent, only return 0 if the code is already indented as fish_indent would, the number of failed files otherwise. Also print the failed filenames if not reading from standard input.

-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=DEBUG_CATEGORIES

  Enable debug output and specify a pattern for matching debug categories. See Debugging in fish (1) for details.

-o or --debug-output=DEBUG_FILE

  Specify a file path to receive the debug output, including categories and `fish_trace`. The default is standard error.

--dump-parse-tree

  Dumps information about the parsed statements to standard error. This is likely to be of interest only to people working on the fish source code.

-h or --help

  Displays help about using this command.
