Multiple stockfish wasms for use in lichess.org web analysis

Building

# Example: Clean and make all debug builds for node with SAFE_HEAP

  ./build.py --flags='-O0 -g3 -sSAFE_HEAP' --node all clean

or to avoid installing or changing your emscripten version, use ./build-with-docker.sh:

./build-with-docker.sh --flags='-O3' all clean

omit --node for default web builds

use --flags to override the default emcc flags which are -O3 -DNDEBUG --closure=1

check ./build.py --help for the latest targets

./build.py downloads sources to the ./fishes folder then applies diffs from the ./patches folder. Edit the Stockfish sources freely. But to contribute your edits, use a patch file

# Example: Update `sf16-7.patch` with your source changes: 

  cd fishes/sf16-7
  git diff > ../../patches/sf16-7.patch
