# 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:
|
2021-04-03 22:02:13 -07:00
|
|
|
- `source ~/dev/emsdk/emsdk_env.sh`
|
2021-04-03 21:58:31 -07:00
|
|
|
- Run the emmake command to build
|
2021-04-03 22:02:13 -07:00
|
|
|
- `emmake make`
|
2021-04-03 21:58:31 -07:00
|
|
|
|
|
|
|
|
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/`
