### Summary
This project allows to convert WASM (Web Assembly) from its binary format into Kotlin code.
This allow for example to compile C or C++ libraries and use them in Kotlin common
in any supported target including JVM, JS and Native.
The converter itself is written in kotlin.
### How to use
Generate a Hello World in WASM:
```bash
echo -e "#include \nint main() { printf(\"hello world\\\n\"); for (int n = 0; n < 10; n++) printf(\"%d,\", n); printf(\"\\\n\"); return 0; }" > hello.c
docker run --rm -v $(pwd):/src -t apiaryio/emcc:1.37 emconfigure emcc hello.c -o hello -O3 -s WASM=1
```
This will generate a `hello.wasm` file.
After that, you can use this project to generate a kotlin executable `kt` file from it:
```bash
echo '#!/usr/bin/env kscript' > hello.kt
cat src/main/kotlin/com/soywiz/wasm/WasmModule.kt >> hello.kt
./wasm2kt.kts hello.wasm >> hello.kt
echo -e "fun main(args: Array) = Module.main(args)" >> hello.kt
chmod +x hello.kt
```
Now you can run it using kscript for example:
```bash
kscript hello.kt
```
### Compile
```bash
wasm2kt.kts -lang kotlin -class Example a.out.wast > Example.kt
JAVA_OPTS="-Xmx2g -Xms128M" kotlinc Example.kt
```
### What's working
* WAST parsing
* WASM parsing
* generating code from WAST generated by `emcc -O0 -g4`
* buggy generating code from WAST generated by `emcc -O3 -g4`
* buggy generated code from wasm
### TO DO
* remaining fixes
* implementing remaining syscalls
* kotlin-common generator
* migrate code to kotlin-common
* generate a kotlin.js version of the generator and publish as a service online
