    ast-redeclare

    1.0.4 • Public • Published

    ast-redeclare Build Status

    Hoist and fold variable declarations within scopes, so that each variable has only one declaration per scope. Don’t touch functions. Useful to normalize code before analysis, like data-flow etc.

    Usage

    npm install ast-redeclare
    var parse = require('esprima').parse;
    var generate = require('escodegen').generate;
    var redeclare = require('ast-redeclare');
     
    var ast = parse(
        'var a = 1, b = 2; if (a > 1) { var c = b; } else {var c = 3;} var d = 4;'
    );
    ast = redeclare(ast);
     
    generate(ast);
    //var a, b, c, d; a = 1; b = 2; if (a > 1) { c = b; } else { c = 3; }; d = 4;
