# 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.

- `-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 stdin.

- `-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 stderr.

- `--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.
