pacman/README.md

+# pacman.c 
+
+A Pacman clone written in C99 with minimal dependencies for Windows, macOS, Linux and WASM.
+
+[WASM version](https://floooh.github.io/pacman.c/pacman.html)
+
+For implementation details see comments in the pacman.c source file (I've tried
+to structure the source code so that it can be read from top to bottom).
+
+Related projects:
+
+- Zig version: https://github.com/floooh/pacman.zig
+
+## Clone, Build and Run (Linux, macOS, Windows)
+
+On the command line:
+
+```
+git clone https://github.com/floooh/pacman.c
+cd pacman.c
+mkdir build
+cd build
+cmake ..
+cmake --build .
+```
+
+> NOTE: on Linux you'll need to install the OpenGL, X11 and ALSA development packages (e.g. mesa-common-dev, libx11-dev and libasound2-dev).
+
+On Mac and Linux this will create an executable called 'pacman'
+in the build directory:
+
+```
+./pacman
+```
+
+On Windows, the executable is in a subdirectory:
+
+```
+Debug/pacman.exe
+```
+
+## Build and Run WASM/HTML version via Emscripten
+
+> NOTE: You'll run into various problems running the Emscripten SDK tools on Windows, might be better to run this stuff in WSL.
+
+Setup the emscripten SDK as described here:
+
+https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
+
+Don't forget to run ```source ./emsdk_env.sh``` after activating the SDK.
+
+And then in the pacman.c directory:
+
+```
+mkdir build
+cd build
+emcmake cmake -G"Unix Makefiles" -DCMAKE_BUILD_TYPE=MinSizeRel ..
+cmake --build .
+```
+
+To run the compilation result in the system web browser:
+
+```
+> emrun pacman.html
+```
+
+## IDE Support
+
+On Windows with Visual Studio cmake will automatically create a **Visual Studio** solution file which can be opened with ```cmake --open .```:
+```
+cd build
+cmake ..
+cmake --open .
+```
+
+On macOS, the cmake **Xcode** generator can be used to create an
+Xcode project which can be opened with ```cmake --open .```
+```
+cd build
+cmake -GXcode ..
+cmake --open .
+```
+
+On all platforms with **Visual Studio Code** and the Microsoft C/C++ and
+CMake Tools extensions, simply open VSCode in the root directory of the
+project. The CMake Tools extension will detect the CMakeLists.txt file and
+take over from there:
+```
+cd pacman.c
+code .
+```
