This documents an old version of fish. See the latest release.
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 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.
