Running instructions

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: (the JS file contains a loader for the .wasm file, without the extension):

   v -prod -os wasm32_emscripten -o examples/2048/index.js examples/2048/
   

4. Run/test the game:

   emrun examples/2048/index.html
   

   If you prefer, instead of emrun, you can start a simple V http file server:

   v -e 'import net.http.file; file.serve(folder: "examples/2048")'   
   

   and then open http://127.0.0.1:4001/ in your browser.

Once you have opened the game in your browser, you can make changes to the V source, then recompile (step 3), and refresh the browser window with the game, to see their effect.
