agly v0.0.1

• ~agly~ , an attribute grammar library for javascript

Here's a simple example which reverses the order of operands in each addition. #+BEGIN_SRC javascript const agly = require('agly'); const recast = require('recast'); const assert = require('chai').assert;

const gr = new agly.Grammar({ BinaryExpression: class extends agly.Node { get rewritten() { const p = this._parse; return p.operator==='+' ? b.binaryExpression('+',p.right,p.left) : p; } } });

console.log(recast.print(gr.load(recast.parse("function fn(a) {\n return a + 1;\n}")).rewritten).code); #+END_SRC

See tests for (not much) more.
