Ambients Reducer

Experimental Ambient Calculus reducer module. Give the reducer an ambient and it will reduce it to its final form.

Input: a[open_] | open a

Output: a[]

See example input format (JSON) which is produced by ambc, an ambients compiler.

Install

git clone https://github.com/haadcode/ambients-reducer.git
npm install

Build

npm run build

Build + Watch

npm run start

Usage

Use as a module in a JavaScript program:

const fs = require("fs")
const deserializer = require("./src/Deserializer.bs.js")
const vm = require("./src/AmbientReducer.bs.js")
const jsonFile = "./__tests__/fixtures/001.json"
const json = fs.readFileSync(jsonFile, "utf8")
const program = deserializer.fromJSON(json)
const result = vm.reduceFully(program)
console.log(JSON.stringify(result, null, 2))

Examples

Run Program1.re:

node src/examples/Program1.bs.js

Output:

--------
initial state:
[]
└─ a[open b]
   ├─ b[in_ c.open c.open_]
   └─ c[in b.open_]
      └─ d[]
--------
final state:
[]
└─ a[]
   └─ d[]

Run Program2.re:

node src/examples/Program2.bs.js
