 - Short options, like ``-a``. Short options are a single character long, are preceded by a single hyphen and can be grouped together (like ``-la``, which is equivalent to ``-l -a``). Option arguments may be specified by appending the option with the value (``-w32``), or, if ``--require-parameter`` is given, in the following parameter (``-w 32``).

 Useful functions for writing completions

-``fish`` ships with several functions that are very useful when writing command specific completions. Most of these functions name begins with the string ``__fish_``. Such functions are internal to ``fish`` and their name and interface may change in future fish versions. Still, some of them may be very useful when writing completions. A few of these functions are described here. Be aware that they may be removed or changed in future versions of fish.

Such functions are internal to ``fish`` and their name and interface may change in future fish versions. A few of these functions are described here.
 
 Functions beginning with the string ``__fish_print_`` print a newline separated list of strings. For example, ``__fish_print_filesystems`` prints a list of all known file systems. Functions beginning with ``__fish_complete_`` print out a newline separated list of completions with descriptions. The description is separated from the completion by a tab character.

 If you are developing another program and would like to ship completions with your program, install them to the "vendor" completions directory. As this path may vary from system to system, the ``pkgconfig`` framework should be used to discover this path with the output of ``pkg-config --variable completionsdir fish``.
