This adds an extra parameter to move_cursor() that's an optional pointer to a bool indicating whether the cursor is visible. This allows for centralising the common idiom of having the keyboard cursor become visible when a cursor key is pressed. Consistently with the vast majority of existing puzzles, the cursor moves even if it was invisible before, and becomes visible even if it can't move. The function now also returns one of the special constants that can be returned by interpret_move(), so that the caller can correctly return MOVE_UI_UPDATE or MOVE_NO_EFFECT without needing to carefully check for changes itself. Callers are updated only to the extent that they all pass NULL as the new argument. Most of them could now be substantially simplified.
This is the README accompanying the source code to Simon Tatham's puzzle collection. The collection's web site is at <https://www.chiark.greenend.org.uk/~sgtatham/puzzles/>. The puzzle collection is built using CMake <https://cmake.org/>. To compile in the simplest way (on any of Linux, Windows or Mac), run these commands in the source directory: cmake . cmake --build . The manual is provided in Windows Help format for the Windows build; in text format for anyone who needs it; and in HTML for the Mac OS X application and for the web site. It is generated from a Halibut source file (puzzles.but), which is the preferred form for modification. To generate the manual in other formats, rebuild it, or learn about Halibut, visit the Halibut website at <https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.
