FISH_INDENT(1) fish-shell FISH_INDENT(1)

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:

Indents a specified file and immediately writes to that file.
Do not indent commands; only reformat to one job per line.
Do not reformat, only indent each line.
Do not reformat, only unindent each line.
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.
Displays the current fish version and then exits.
Colorizes the output using ANSI escape sequences using the colors defined in the environment (such as fish_color_command <#envvar-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.
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.
Displays help about using this command.
