Fix the Java front end's vertical text positioning when
ALIGN_VNORMAL is in use: ALIGN_VNORMAL indicates that the supplied
y-coordinate denotes the _baseline_ of the text, not its top, so
adding on 'asc' to convert to the baseline is wrong.

This only affects Tents, at present.

Couple of solving-related mid-end tweaks. Firstly, when we generate
a game which comes with an aux string, we immediately self-test that
string by passing it to solve() and test by assertion that it
succeeded. So a bug in a back end which intermittently generates
malformed aux strings will be detected as soon as it occurs, instead
of only if the user happens to use the Solve operation on a
particular game in which it happened.

Secondly, Ctrl-S now (undocumentedly) triggers the Solve operation,
on the general principle that keyboard shortcuts tend to come in
handy, and on the specific principle that if you want to look at
lots of solved grids in quick succession (say, when observing their
general shape and nature to see if your generation algorithm was
good or not) it's handy to have a quick way of getting to them.

simon [Wed, 17 Sep 2008 16:43:36 +0000 (16:43 +0000)]
Yet another complete rewrite of Slant's loop detection during
gameplay. Having tried methods based on using the slashes to define
a dsf on grid vertices, and also methods based on tracing round the
loops using conventional (non-dsf-based) graph theory, it occurred
to me the other day that there's a far simpler technique involving
connectivity. A loop is precisely that which causes the playing area
to become disconnected; so what we do now is to go through and build
a dsf describing connectedness of the _area_ of the grid rather than
the vertices. That divides the area into its maximal connected
components, and then we can trivially identify every edge that's
part of a loop by noticing that it separates two nonequivalent
pieces of space. The resulting algorithm is half the size of the old
one, and it's much easier to be confident of its correctness.

(Having said which, there will doubtless turn out to be an
embarrassing bug in it, but I haven't found it yet.)

New infrastructure feature. Games are now permitted to be

item to be greyed out depending on the game_params.

simon [Tue, 8 Apr 2008 09:36:33 +0000 (09:36 +0000)]
Improvements to filled-grid generation. Introduced a cunning idea
suggested by IWJ last night: grid generation can immediately choose
an entire grid row randomly, since all that's doing is nailing down
the names of the numbers, and that gets the whole thing started more
efficiently. But the main difference is that now grid generation is
given only area^2 steps to come up with a filled grid, and then cut
off unceremoniously, causing grid generation to fail and be retried
from scratch. This seems to prevent hangups on jigsaw layouts that
admit few useful solutions, by changing layout constantly. 9j
puzzles now generate at a sensible rate, and as an added bonus so do
5x5 normal puzzles, which they never used to.

16 years agoSubstantial reworking of Solo so that it implements both Sudoku-X
simon [Mon, 7 Apr 2008 15:56:42 +0000 (15:56 +0000)]
Substantial reworking of Solo so that it implements both Sudoku-X
(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.

Hmm. Telling xvfb to default to a TrueColor visual did help, in that
it got rid of the bogus backgrounds on all the text; but on the

start with. Instead, we'll just tell xvfb to use a 24-bit display

Update the OS X Puzzles makefile so that it builds on Leopard and
generates PPC/Intel dual-architecture binaries.

This turns out not to be too painful: you compile and link your
programs using `gcc -arch ppc' or `gcc -arch i386', then you use a
command of the form `lipo -create ppc-binary i386-binary -output
binary' to construct a universal binary. It works equally well on
command-line standalone executable files and the executables within
application directories. Also added the -mmacosx-version-min option,
since otherwise the OS X build tools appear to default to building
binaries which will crash (without anything resembling a
comprehensible error message) on any earlier release.

The handling of version.o in this checkin is somewhat grotty. I'd
prefer a method more cleverly intertwingled with mkfiles.pl so I
didn't have to maintain the OS X architecture list in both
mkfiles.pl and Recipe. (Not that I anticipate Apple switching
architectures again in the immediate future, but it's the principle
of the thing.)
