# fish\_indent(1)

indenter and prettifier

## NAME

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 using the colors defined in the environment (such as **fish\_color\_command** \<#envvar-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**.

- **--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.
