sgt-puzzles-aho-extensions

Anders Holst's extensions to Simon Tatham's puzzle collection

This package contains a number of puzzles I have written for Simon Tatham's Portable Puzzle Collection but which have not made it into the official package. Nevertheless, they are fully playable and complete.

The puzzles:

Click on a puzzle below for the full description of it.

Kakuro Fill the board so that unique numbers sum up to each clue	Factorcross Fill the board so that the numbers' products match the clues	Alphacrypt Assign a number to each letter such that the equations match
Identifier Identify the forms and positions of shapes in a board	Supermaze Find your way through the Supermazes, i.e mazes with states

How to install:

You will need both the source code in this package, and the code of the SGT puzzle collection. This extension package was recently compiled together with a version of the SGT puzzles from January 2022, but sometimes the interface changes, so give me a notice if I need to update my code.

To download and install, follow these steps:

• Download this package from Github. For example, on Linux you can do this by going into (with "cd") the directory where you want your source code, and running:

git clone git@github.com:Anders-Holst/sgt-puzzles-aho-extensions.git

• If you have not done so already, also get the source code for the SGT Portable Puzzle Collection from the official site. Download it, unpack it, and move into the resulting directory.

mv -f puzzles.tar.gz puzzles.tar.gz.old
wget https://www.chiark.greenend.org.uk/~sgtatham/puzzles/puzzles.tar.gz
tar xzf puzzles.tar.gz
cd  `tar tzf puzzles.tar.gz | head -1` 

• Copy thie extension package directory into the SGT puzzles directory as a subdirectory called aho-extensions: Assuming that you followed the above commands, you can do:

cp -a ../sgt-puzzles-aho-extensions ./aho-extensions

• In the SGT puzzles repository's CMakeLists.txt, add the line add_subdirectory(aho-extensions) to include the extensions in the compilation:

mv CMakeLists.txt CMakeLists.txt.orig
sed 's|add_subdirectory(unfinished)|add_subdirectory(unfinished)\nadd_subdirectory(aho-extensions)|' < CMakeLists.txt.orig > CMakeLists.txt

• You also need to apply a small modification to one file in the SGT code: Remove the word "static" in front of the function midend_undo in the file "midend.c". This is needed to be able to use multi-digit numbers. For example, you can do this by the commands:

mv midend.c midend.c.orig
sed 's|static bool midend_undo(|bool midend_undo(|' < midend.c.orig > midend.c

• Run CMake and make in the SGT puzzles folder:

cmake .
make clean
make

• If you have super-user rights on your computer, you can now install all the puzzles with:

sudo make install

Otherwise the extension binaries are located in the aho-extensions subdirectory in the SGT puzzles source directory.

• You are done. Enjoy!
