javascript: Add new port targeting JavaScript via Emscripten.
In this port JavaScript is the underlying "machine" and MicroPython is transmuted into JavaScript by Emscripten. MicroPython can then run under Node.js or in the browser.

MicroPython.js
|
||||
==============
|
||||
|
||||
MicroPython transmuted into Javascript by Emscripten.
|
||||
|
||||
Dependencies
|
||||
------------
|
||||
|
||||
Building micropython.js bears the same requirements as the standard MicroPython
|
||||
ports with the addition of Emscripten (and uglify-js for the minified file).
|
||||
|
||||
A standard installation of Emscripten should provide functional code, however
|
||||
if memory errors are encountered it may be worthwhile to modify the tool.
|
||||
`emscripten-fastcomp/lib/Target/JSBackend.cpp` may require the minor fix
|
||||
found in JSBackend.patch. This patch attempts to address situations where
|
||||
C code running through Emscripten is denied access to Javascript variables
|
||||
leading to false-positives in the MicroPython garbage collector as variables
|
||||
with pointers exclusively in Javascript will be erased prematurely.
|
||||
Refer to Emscripten documentation for instructions on building Emscripten
|
||||
from source.
|
||||
|
||||
Build instructions
|
||||
------------------
|
||||
|
||||
In order to build micropython.js, run:
|
||||
|
||||
$ make
|
||||
|
||||
To generate the minified file micropython.min.js, run:
|
||||
|
||||
$ make min
|
||||
|
||||
Running with Node.js
|
||||
--------------------
|
||||
|
||||
Access the repl with:
|
||||
|
||||
$ node build/micropython.js
|
||||
|
||||
Stack size may be modified using:
|
||||
|
||||
$ node build/micropython.js -X stack=64K
|
||||
|
||||
Where stack size may be represented in Bytes, KiB or MiB.
|
||||
|
||||
MicroPython scripts may be executed using:
|
||||
|
||||
$ node build/micropython.js hello.py
|
||||
|
||||
Alternatively micropython.js may by accessed by other javascript programs in node
|
||||
using the require command and the general API outlined below. For example:
|
||||
|
||||
```javascript
|
||||
var mp_js = require('./build/micropython.js');
|
||||
|
||||
mp_js_init(64 * 1024);
|
||||
mp_js_do_str("print('hello world')\n");
|
||||
```
|
||||
|
||||
Running with HTML
|
||||
-----------------
|
||||
|
||||
The prerequisite for browser operation of micropython.js is an element with
|
||||
the id `mp_js_stdout` which receives `print` events. The following code
|
||||
demonstrates basic functionality:
|
||||
|
||||
```html
|
||||
<!doctype html>
|
||||
<html>
|
||||
<head>
|
||||
<script src="build/micropython.js"></script>
|
||||
</head>
|
||||
<body>
|
||||
<div id='mp_js_stdout'></div>
|
||||
<script>
|
||||
mp_js_stdout.addEventListener('print', function(e) {
|
||||
document.write(e.data);
|
||||
}, false);
|
||||
|
||||
mp_js_init(64 * 1024);
|
||||
mp_js_do_str('print(\'hello world\')');
|
||||
</script>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
MicroPython code execution will suspend the browser so be sure to atomize usage
|
||||
within this environment. Unfortunately interrupts have not been implemented for the
|
||||
browser.
|
||||
|
||||
Testing
|
||||
-------
|
||||
|
||||
Run the test suite using:
|
||||
|
||||
$ make test
|
||||
|
||||
API
|
||||
---
|
||||
|
||||
The following functions have been exposed to javascript.
|
||||
|
||||
```
|
||||
mp_js_init(stack_size)
|
||||
```
|
||||
|
||||
Initialize MicroPython with the given stack size in bytes. This must be
|
||||
called before attempting to interact with MicroPython.
|
||||
|
||||
```
|
||||
mp_js_do_str(code)
|
||||
```
|
||||
|
||||
Execute the input code. `code` must be a `string`.
|
||||
|
||||
```
|
||||
mp_js_init_repl()
|
||||
```
|
||||
|
||||
Initialize MicroPython repl. Must be called before entering characters into
|
||||
the repl.
|
||||
|
||||
```
|
||||
mp_js_process_char(char)
|
||||
```
|
||||
|
||||
Input character into MicroPython repl. `char` must be of type `number`. This
|
||||
will execute MicroPython code when necessary.
