fish_indent - indenter and prettifier


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.

-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.


Colorizes the output using ANSI escape sequences, appropriate for the current TERM, using the colors defined in the environment (such as fish_color_command).


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.


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.
