Empty suffix is a perfectly good suffix, hence the loop `forsuffixes $ := s : or true endfor' yields always true even if the text argument is empty. So, we have to use a `for' loop for testing for presence of a non-empty list of suffixes. If it is not empty, we may selectively initialise x and y variables with the suffixes mentioned in the list.

Redefining space is (afaik) not possible but special chars can probably be nilled temporarily.

Only with a macro that takes arguments. A real dirty way out is: let def = vardef ; since vardef's work well. It all depends on what metapost expects. An expression should conform to certain syntax rules, while afaik is just grabbed upto the next ; I think that most things can be a suffix, but some tokens are intercepted by the input scanner. In TeX, one can play with catcodes and doing what you want would not be hard there, but then, tex does not have the nice non interference (grouping) features. Actually, most differences in the macro language make sense and is spit eof what one may think, even the strange thinsg make sense once you run into some special cases. I think that the mp interface was not designed for implementing interfaces, but for expression handling.

In MFpic, we have a command that draws a function. I considered similar ideas, but mainly rejected them for ease of use. It would be difficult (in MF) to calculate or estimate a derivative, so the user interface would require a command whose arguments include both the function and its derivative. Most users don't want (or don't know how) to specify a derivative. In MFpic we settled on specifying the function. The code then calculates the points z_n plus specifies the direction at each point z_n to be z_{n+1)-z_{n-1} (which is essentially just a very simple way to estimate the derivative). A knowledge of the derivative would indeed usually allow for fewer points, but would involve twice as many calculation: evaluating the function expression as well as that of the derivative. On the other hand that allows one to explicitly tell MF the control points (as in z1..controls z2 and z3..z4) which would apparently be more efficient to MF as it wouldn't have to optimize over the whole curve. -- Daniel H.

Because the equations must be scale invariant, they are homogeneous and because they must be translation invariant, they can depend only on the differences between the points. This means we can take one of the points to be (0,0) and we have equations in the other three points. Now we also have rotation invariance, so the equation must be z-scale invariant, which means we have complex linear equations AZ = 0, where A is an n-by-3 matrix and Z is a triple of complex numbers (the three points). It is easy to come up with 2 complex-linearly independent values for Z that come from rectangles, so A has rank 1 (i.e., it is essentially a 1-by-3 matrix of complex numbers. It is then a matter of putting in a couple of different values of Z to show that the equation is the same as the one for parallelograms, perhaps multiplied by a complex constant. Thus any equation true for all rectangles automatically includes all parallelograms. In fact, if orientation is taken into account (in the differential geometric sense that z1--z2--z3--z4--cycle is taken to be different from its reversal z1--z4--z3--z2--cycle) the above argument is valid for squares as well. >Also possible is describing points of an unknown square: >z4-z1=z3-z2; z3-z1=(y2-y4,x4-x2); The second equation is valid only if the orientation of the square is counterclockwise. Oriented clockwise, the sign of the of the right-hand side would be reversed. Any linear equations valid for all squares of all orientations will reduce to the parallelogram equation. > >A rectangle with unknown points just seems to be one unknown too much to >state it without having more information. Also true for squares. The extra information needed is the orientation, and the only means of stating that in an equation is non-linearly. -- Daniel H.

Just put TXP in C:\localtexmf\metapost and refresh the filename database. Move the example file to an external directory, create a tex file with an appropriate \includegraphics command, and take a look!
