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, 1 otherwise.
|
|
|
|
- ``-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-level=DEBUG_LEVEL`` enables debug output and specifies a verbosity level. Defaults to 0.
|
|
|
|
- ``-D`` or ``--debug-stack-frames=DEBUG_LEVEL`` specify how many stack frames to display when debug messages are written. The default is zero. A value of 3 or 4 is usually sufficient to gain insight into how a given debug call was reached but you can specify a value up to 128.
|
|
|
|
- ``--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.
