puzzles/LICENCE, branch rockbox My sgt-puzzles tree Add printing support for GTK. 2019-12-30T08:10:34+00:00 Asher Gordon AsDaGo@posteo.net 2019-12-24T03:37:27+00:00 b443a84efe1a03fc0e06cf71b1a0632c5a3c99a3 Printing is only available in GTK versions >= 2.10.

In GTK, printing is usually done one page at a time, so also modify printing.c to allow printing of a single page at a time. Create a separate drawing API for drawing to the screen and for printing. Create a vtable for functions which need to be different depending on whether they were called from the printing or drawing API. When a function is called from the printing API, it is passed a separate instance of the frontend than if it were called from the drawing API. In that instance of the frontend, an appropriate vtable is available depending on whether it was called from the printing or drawing API.

For example, using Cairo as a printing backend when printing from the command line. Enabling the low-level functions even when GTK printing is not available also allows them to be compiled under as many build settings as possible, and thus lowers the chance of undetected breakage.

Printing is only available in GTK versions >= 2.10. We can only embed
the page setup dialog on GTK >= 2.18, so on a GTK version less than
that, we must use a separate page setup dialog.

In GTK, printing is usually done one page at a time, so also modify
printing.c to allow printing of a single page at a time.

Create a separate drawing API for drawing to the screen and for
printing. Create a vtable for functions which need to be different
depending on whether they were called from the printing or drawing
API.

When a function is called from the printing API, it is passed a
separate instance of the frontend than if it were called from the
drawing API. In that instance of the frontend, an appropriate vtable
is available depending on whether it was called from the printing or
drawing API.

The low-level functions used for printing are enabled even if printing
is not enabled. This is in case we ever need to use them for something
other than printing with GTK. For example, using Cairo as a printing
backend when printing from the command line. Enabling the low-level
functions even when GTK printing is not available also allows them to
be compiled under as many build settings as possible, and thus lowers
the chance of undetected breakage.

Move the definition of ROOT2 from ps.c to puzzles.h so other files can
use it (gtk.c needs it for hatching).

Also add myself to the copyright list.

[Committer's note: by 'printing', this log message refers to the GTK
GUI printing system, which handles selecting a printer, printing to a
file, previewing and so on. The existing facility to generate
printable puzzles in Postscript form by running the GTK binaries in
command-line mode with the --print option is unaffected. -SGT]
Standardise character encoding of source tree on UTF-8. 2017-11-18T15:27:37+00:00 Simon Tatham anakin@pobox.com 2017-11-18T15:22:49+00:00 5c6fcf10a363c73b00f0daa752ccf9d133a35793 Editing LICENCE just now, I happened to notice that the accented letter in Jonas Kölker's name was encoded in ISO 8859-1, as is the occurrence of the same name in filling.c - but _not_ the one in guess.c, which was in UTF-8 already. That seems needlessly confusing, so let's sort it out. Now every text file in this git repository is suitable for interpreting as UTF-8.

Patch from Rogier Goossens to speed up the Pattern solver. 2013-04-12T16:28:55+00:00 Simon Tatham anakin@pobox.com 2013-04-12T16:28:55+00:00 383c15794a517a4e6dc0b7364edac1f7056cee82 do_recurse() now prunes early whenever it encounters a branch of the search tree inconsistent with existing grid data (rather than the previous naive approach of proceeding to enumerate all possibilities anyway and then ruling them out one by one); do_recurse also tries to split the row up into independent sections where possible; finally the main solver loop (all three copies of which have now been factored out into a new solve_puzzle function), instead of simply looping round and round over all the rows and columns, heuristically looks at the ones most changed since the last time deduction was attempted on them, on the basis that that will probably yield the most information the fastest.

do_recurse() now prunes early whenever it encounters a branch of the
search tree inconsistent with existing grid data (rather than the
previous naive approach of proceeding to enumerate all possibilities
anyway and then ruling them out one by one); do_recurse also tries to
split the row up into independent sections where possible; finally the
main solver loop (all three copies of which have now been factored out
into a new solve_puzzle function), instead of simply looping round and
round over all the rows and columns, heuristically looks at the ones
most changed since the last time deduction was attempted on them, on
the basis that that will probably yield the most information the
fastest.
