Most of these aren't especially useful, but if we're going to have
them in the code base at all, we should at least ensure they compile:
bit-rotted conditioned-out code is of no value.
One of the new programs is 'galaxieseditor', which borrows most of the
Galaxies code but changes the UI so that you can create and remove
_dots_ instead of edges, and then run the solver to see whether it can
solve the puzzle you've designed. Unlike the rest, this is a GUI
helper tool, using the 'guiprogram' cmake function introduced in the
previous commit.
The programs are:
- 'combi', a test program for the utility module that generates all
combinations of n things
- 'divvy', a test program for the module that divides a rectangle at
random into equally-sized polyominoes
- 'penrose-test', a test program for the Penrose-tiling generator
used in Loopy, which outputs an SVG of a piece of tiling
- 'penrose-vector', a much smaller test program for the vector
arithmetic subroutines in that code
- 'sort-test', a test of this code base's local array sorting routine
- 'tree234-test', the exhaustive test code that's been in tree234.c
all along.
Not all of them compiled first time. Most of the fixes were the usual
kind of thing: fixing compiler warnings by removing unused
variables/functions, bringing uses of internal APIs up to date. A
notable one was that galaxieseditor's interpret_move() modified the
input game state, which was an error all along and is now detected by
me having made it a const pointer; I had to replace that with an extra
wrinkle in the move-string format, so that now execute_move() makes
the modification.
The one I'm _least_ proud of is squelching a huge number of
format-string warnings in tree234-test by interposing a variadic
function without __attribute__((printf)).

This is the main bulk of this boolification work, but although it's
making the largest actual change, it should also be the least
disruptive to anyone interacting with this code base downstream of me,
because it doesn't modify any interface between modules: all the
inter-module APIs were updated one by one in the previous commits.
This just cleans up the code within each individual source file to use
bool in place of int where I think that makes things clearer.

This commit removes the old #defines of TRUE and FALSE from puzzles.h,
and does a mechanical search-and-replace throughout the code to
replace them with the C99 standard lowercase spellings.

(require both main diagonals to have one of every digit in addition
to all the usual constraints) and Jigsaw Sudoku (replace the array
of rectangular sub-blocks with the sub-blocks being random
polyominoes). To implement the latter, I've moved my `divvy.c'
library routine out of the `unfinished' subdirectory.
Jigsaw mode is currently an undocumented feature: you enable it by
setting the rows parameter to 1 (and the columns parameter to your
desired grid size, which unlike normal Sudoku can be anything you
like including a prime number). The reason it's undocumented is
because generation times are not yet reliably short: sometimes
generating a jigsaw-type puzzle can hang for hours and still get
nowhere. (The algorithm should terminate in principle, but not in
any time you're prepared to wait.) I _think_ I know how to solve
this, but have yet to try it. Until then, jigsaw mode will remain a
hidden feature.
Printing of X-type puzzles is also substandard at present, because
the current print-colour API replaces the desired light shading of
the X-cells with heavy diagonal hatching. I plan to adjust the API
imminently to address this.
