Discover the variable names chosen for each of a file's top-level required modules.
Won't pick up nested requires in if/for statements or inside functions, but is intended for detecting the names of variables to replace e.g. when creating inlining transforms such as brfs.
Usage
requires = sleuth(ast)
Accepts an esprima-like ast
object.
Returns an object whose keys represent the variable names used to require a module, and whose values are the required module strings detected.
Example
var esprima = require('esprima')
var walkers = require('astw')
var files = require('fs')
var src = files.readFileSync(__filename, 'utf8')
var ast = esprima.parse(src)
// Walk the generated AST
var result = sleuth(ast)
console.log(result)
// Or you can try it this way:
var result = sleuth(walkers(src))
console.log(result)
Which should give you back something like this:
{
esprima: 'esprima',
walkers: 'astw',
files: 'fs'
}
