Elevator pitch
|
|
--------------
|
|
A programming language, that looks like Python, handles like Haskell,
|
|
and compiles directly to WebAssembly.
|
|
|
|
Name origin
|
|
-----------
|
|
- p from python
|
|
- ha from Haskell
|
|
- asm from WebAssembly
|
|
|
|
Example
|
|
-------
|
|
For more examples, see the examples directory.
|
|
```py
|
|
def helper(n: u64, a: u64, b: u64) -> u64:
|
|
if n < 1:
|
|
return a + b
|
|
|
|
return helper(n - 1, a + b, a)
|
|
|
|
@exported
|
|
def fib(n: u64) -> u64:
|
|
if n == 0:
|
|
return 0
|
|
|
|
if n == 1:
|
|
return 1
|
|
|
|
return helper(n - 1, 0, 1)
|
|
```
|
|
|
|
Gotcha's
|
|
--------
|
|
- When importing and exporting unsigned values to WebAssembly, they will become
|
|
signed, as WebAssembly has no native unsigned type. You may need to cast
|
|
or reinterpret them.

------------
|
|
At this time, I'm mostly looking for use cases for WebAssembly, other than to
|
|
compile existing C code and running them in the browser. The goal of WebAssembly
|
|
is to enable high-performance applications on web pages[5]. Though most people
|
|
seem to use it to have existing code run in the browser.
|
|
|
|
If you have a situation where WebAssembly would be useful for it's speed, I'm
|
|
interested to see what you want to use it for.
|
|
|
|
Also, if you are trying out Phasm, and you're running into a limitation, I'm
|
|
interested in a minimal test case that shows what you want to achieve and how
|
|
Phasm currently fails you.
|
|
|
|
Additional required tools
|
|
-------------------------
|
|
At the moment, the compiler outputs WebAssembly text format. To actually
|
|
get a binary, you will need the wat2wasm tool[6].
