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 +%
