See shell.html::entrypoint() for the JS side of things. See wasm_main.cpp for the C++ side of things (EMSCRIPTEN_BINDINGS at the bottom is what glues the two parts together - in general the strings are for JS and the not strings are the C++) To build this yourself, follow the getting started instructions: https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html and download this patch. Then, update compile.sh to point at your sdk and run it (e.g. $SKIA_ROOT/experimental/wasm/compile.sh) Then navigate a browser (e.g. Chrome) to http://localhost:8000/out/wasm/pathkit.html So far, can compile with compile.sh, but not really with GN/ninja (the compilation into many object files and a link at the end seems to mess emscripten up) Bug: skia: Change-Id: If6b300e2b102469e17841265c7866f1a81094d70 Reviewed-on: https://skia-review.googlesource.com/137422 Reviewed-by: Florin Malita <fmalita@chromium.org> Reviewed-by: Mike Reed <reed@google.com> Commit-Queue: Florin Malita <fmalita@chromium.org>
