Install emscripten sdk from https://emscripten.org/
Make the emsdk available to your terminal/PATH
- for example:
- source ~/dev/emsdk/emsdk_env.sh
Run the emmake command to build
- emmake make

That should be all. This builds a js + wasm file for the page.

How does the page work?

The page is at doc/site/try/template.html.

It loads wren_try.js which loads wren_try.wasm. The page uses emscripten API to call the wren_compile C function, found in main.try.c. The page hooks up printf logging to the console for display.

Notes

The binaries land in bin/wren_try.wasm and bin/wren_try.js when building
The default html output from emsripten is not used, doc/site/try/template.html is
The wren_try.js and wren_try.wasm files are copied to doc/site/static
The make project is a modified version of projects/make
The code relies on code in test/
