@node Overview
@chapter Overview

@command{auto-auto-complete} provides a LISP-like
@footnote{A sane alternative to using XML.} declarative
language for creating auto-completion scripts for commands
in a shell-agnostic way. The current version of
@command{auto-auto-complete} can use such files to generate
auto-completion scripts for the @command{bash}, @command{zsh}
and @command{fish} shells.

@command{auto-auto-complete}'s language limited in comparsion
to for example raw auto-completion scripts for the @command{bash}
shell, however it is well enough for most projects.



@node Invoking
@chapter Invoking

@command{auto-auto-complete} recognises two options:

@table @option
@item -o
@itemx --output OUTPUT_FILE
Specifies the pathname of the generated file.

@item -s
@itemx -f
@itemx --file
@itemx --source SOURCE_FILE
Specifies the pathname of the auto-auto-complete script.
@end table

Both of these options must be used. Additionally
the shell that the generate file should be generated
for must be specified; this is done by adding name
of the shell as a stand-along argument, for example
@command{auto-auto-complete bash --output mycmd.bash --source mycmd.autocomplete}

It is also possible to define variables that can be
used the auto-auto-complete script. If you, for example,
want to give the variable @var{command} the value
@code{mycmd}, add the argument @option{command=mycmd}.
It is also possible to define arrays, for example
if you want the variable @var{srcopt} to be an array
of the for values @code{-s}, @code{-f}, @code{--source}
and @code{--file}, add the arguments @option{srcopt=-s},
@option{srcopt=-f}, @option{srcopt=--source} and
@option{srcopt=--file}. It is not possible to have
variable whose name begin with a dash (`-').



@node Syntax
@chapter Syntax

@command{auto-auto-complete} uses a LISP-like free form
syntax. Valid whitespace is normal blank space, horizontal
tab space@footnote{Also know simply as tab.},
carriage return@footnote{The first character in a new line
in for example the HTTP protocol and in Window's encoding
for new lines, it was the new line character in the classical
Mac operating systems}, line feed (new line) and form feed
(new page). Comments can be started with either a semicolon
(;) or a hash (#). Comments end at the next following
new line, which may either be a carriage return, line feed
or form feed. Comments cannot be started inside quotes.

The backslash character (\) can be used to force the
following character to be parsed verbatim, this is called
escaping. It is highly discourage to use this to escape
new lines, especially if the new line encoding used in the
document is carrige return–line feed, as that would only
escape the carrige return. There is also a set of characters
that have a special meaning when they are escaped:

@table @asis
@item a
Audible bell character.
@item b
Backspace character.
@item e
Escape character.
@item f
Form feed character.
@item n
Line feed character.
@item r
Carriage character.
@item t
Horizontal tab space character.
@item v
Vertical tab space character.
@item 0
Null character.
@end table

Quotes, either simple quotes (') or double quotes (")
can be used to parse all character verbatim except
backslash (\). A quote ends at the next quote character
that is not escaped by a backslash (\) and is identical
to the opening quote character. This is especially useful
for escaping whitespace and round brackets.
