# try wren implementation
This is the code to build the https://wren.io/try wasm component.
### How to build
- 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/
