# slash-a-js
Javascript/WASM bindings for the [Slash/A interpreter](https://github.com/arturadib/slash-a).
## Usage
```javascript
// manually create some source code
const source = 'input/0/save/input/add/output/.' // adds x+y
// convert it into bytecode
const bytecode = SlashA.source2ByteCode(source)
// setup the input buffer
const input = new SlashA.VectorDouble()
input.push_back(2)
input.push_back(3)
// set limits on tape size (data and label)
const DATA_SIZE = 10
const LABEL_SIZE = 10
// provide random seed (can be set to some constant for deterministic runs)
const RAND_SEED = Math.floor(Math.random() * 2147483647)
// set limits on runtime and loop depth
const MAX_RUNTIME = 10
const MAX_LOOP_DEPTH = 10
// run the bytecode
const output = SlashA.runByteCode(bytecode, input, DATA_SIZE, LABEL_SIZE, RAND_SEET, MAX_RUNTIME, MAX_LOOP_DEPTH)
// check that the code did not fail (due to runtime or max loop depth being exceeded)
if (SlashA.checkFailed()) {
throw new Error('Code failed!')
}
// examine output
console.log((new Array(output.size())).map(_, i) => output.get(i)) // [5]
// cleanup
bytecode.delete()
input.delete()
output.delete()
```
Bytecode can also be created directly, without any source code.
```javascript
const bytecode = new SlashA.ByteCode()
bytecode.push_back(1)
```
## Installation
```html
var SlashA = {
onRuntimeInitialized: function () {
// ready to use
const bytecode = new SlashA.ByteCode()
}
}
```
