% 1. macro parameter-defaulting mechanism.
% 2. user stack and dynamic array
% Particularly useful if you have macros with many parameters, and you
% don't want to remember all of them all the time.
%
% Author: Zhuhan Jiang, University of New England, Australia

%
% NOTES:
% 1. This style file can be loaded in as many times as you want,
% without overrunning the resources for such as counter
% registers and etc. So different packages may all use it to
% default their macro parameters, without causing any conflict.
% 2. Macro parameters that can be defaulted through this style file
% are those included in square brackets. E.g. #1, #2, #3 in
% \foo[#1][#2][#3]#4#5 are defaultable while #4 and #5 here are
% not.
% 3. If \foo is a macro to be defaulted, the original macro \foo
% will be renamed as ``\foo@ raw'' (yes, there is a space) and
% the new macro \foo will be defined through the use of the
% original ``\foo@ raw''.
%
% MAIN MACRO:
% \setdefalut{cmdname}{n}{default1}{..}{default_n}
% - gives defaults to \cmdname[p_1][p_2]..[p_n]
% (the macro to be defaulted must be already defined
% when \setdefault is executed)
% EXAMPLES:
% 1. Suppose \foo is defined for \foo[#1][#2][#3]{#4}, we may default
% all (or some of) the parameters in the SQUARE BRACKETS to for
% instance 'one', 'two' and 'three' via
% \setdefault{foo}{3}{one}{two}{three}
% This way, command \foo{stuff} or \foo[]{stuff} or \foo[][]{stuff}
% or \foo[][][]{stuff} will all be translated as
% \foo[one][two][three]{stuff}. Command \foo[][2]{stuff} will be
% translated as \foo[one][2][three]{stuff}.
% 2. See how \placebox is defined and redefined via \setdefault
% in this file.
%
% TIP:
% The best strategy to define (e.g.) \foo[#1][#2]{#3} so that
% it has defaults for #1 and #2
% 1. define \foo@[#1][#2]#3 as normal (what you wish)
% 2. define \foo[#1][#2]#{\foo@[#1][#2]} to make {#3} mandatory
% 3. use \setdefault{foo}{2}{one}{two} to default #1=one and #2 to two
%
% MINOR MACROS:
% \placebox[#1][#2][#3][#4][#5][#6]{#7}
% - place stuff #7 in a box at the position specified
% by parameters #1, ..., #6. (move mini page around)
% #1: box position (default 0)
% 1--6--2 <-- top of the box
% | |
% | |
% | |
% 9 5 7 0 is -5 <-- middle height of the box
% | |
% 10 11 12 <-height up <-- baseline
% | | depth down
% 4--8--3 <-- bottom of the box
% #1<=0: box has no width, no height
% #2: x shift (default 0pt)
% #3: y shift (default 0pt)
% #4,#5: extra x,y shift in multiple of box width/10, height/10
% #6: box type: v=vbox, otherwise=hbox
% #7: content to be boxed
% \push{ ... } - push stuff to stack; anything can be saved to
% \pop - pop stack
% \popnil - delete stack top element (pop to nil)
% \fetch{#1} - fetch #1-th entry from the stack
% (illegal number #1 will produce \relax)
% if #1>0, fetch #1-th entry from bottom of stack
% if #1>=0, fetch (-#1)-th element from top of stack
% e.g.
% fetch{0} - fetch the element of the top of stack
% fetch{-1} - the element just below the top of stack
% fetch{2} - 2nd element from the bottom of stack
