API

rename(node, from, to)

Recursively renames all identifiers with the name from within node to to. It will abort once it reaches a scope where from is shadowed.

var parse = require('esprima').parse
rename(parse('var a = 1'), 'a', 'b') // => parse('var b = 1')
rename(parse('a;var a'), 'a', 'b') // => parse('b;var b')
rename(parse('function a(a){a}'), 'a', 'b') // => parse('function b(a){a}')
rename(parse('try{a}catch(a){a}'), 'a', 'b') // => parse('try{b}catch(a){a}')
