Dependencies (Ubuntu/Debian)

sudo apt install -y libx11-dev libxi-dev libxcursor-dev libxrandr-dev libgl-dev

Compiling to JS

v -b js_browser examples/tetris/tetris.js.v

And then open index.html with your favourite web browser.

Compiling to WASM

1. Install Emscripten from https://emscripten.org/docs/getting_started/downloads.html
2. Make sure that the environment in your shell is setup correctly, i.e. that emcc --version works.

   . /opt/emsdk/emsdk_env.sh
   emcc --version
   

3. Compile the game to WASM:

   v -skip-unused -prod -os wasm32_emscripten examples/tetris/`
   

4. Copy the generated tetris file to index.js This can be done once. Note that this step will be removed soon, when the option -os wasm32_emscripten becomes better integrated:

   cp examples/tetris/tetris examples/tetris/tetris.js
   

5. Run/test the game:

   emrun examples/tetris/index.html
   

   Once you have run the game, you can make changes, then just recompile (step 3), and refresh the game in your browser.
