# WasmCompiler.jl
This is essentially a rewrite of [Charlotte.jl](https://github.com/MikeInnes/Charlotte.jl) (a lot has changed since 2018, both in WebAssembly and Julia land) targeting the new WebAssembly proposals ([gc](https://github.com/WebAssembly/gc),[exceptions](https://github.com/WebAssembly/exception-handling),...).
## Example
```julia
julia> using WasmCompiler
julia> relu(x) = ifelse(x < zero(x), zero(x), x)
relu (generic function with 1 method)
julia> @code_wasm relu(1f0)
(func $relu (param f32) (result f32)
(local i32 f32)
block
local.get 0
f32.const 0.0
f32.lt
local.set 1
f32.const 0.0
local.get 0
local.get 1
select
local.set 2
local.get 2
nop
return
end
unreachable
)
julia> @code_wasm optimize=true relu(1f0)
(func $relu (param f32) (result f32)
(local i32)
local.get 0
f32.const 0.0
f32.lt
local.set 1
f32.const 0.0
local.get 0
local.get 1
select
)
julia> @code_wasm mod=true sexpr=true optimize=true relu(1f0) # Use sexpr=true to display as WAST
(module
(func $relu (param f32) (result f32)
(local i32)
(local.set 1
(f32.lt
(local.get 0)
(f32.const 0.0)))
(select
(f32.const 0.0)
(local.get 0)
(local.get 1))
)
(export "relu" (func $relu)))
julia> # with an extra optimizer effort we can move the cond local
@code_wasm optimize=2 sexpr=true relu(1f0)
(module
(func $relu (param f32) (result f32)
(select
(f32.const 0.0)
(local.get 0)
(f32.lt
(local.get 0)
(f32.const 0.0)))
)
(export "relu" (func $relu))
)
```
