methods

var detective = require('detective');

detective(src, opts)

Give some source body src, return an array of all the require() calls with string arguments.

The options parameter opts is passed along to detective.find().

detective.find(src, opts)

Give some source body src, return an object with "strings" and "expressions" arrays for each of the require() calls.

The "expressions" array will contain the stringified expressions.

Optionally you can specify a different function besides "require" to analyze with opts.word.

You can also specify opts.nodes = true in order to include a "nodes" array which contains an AST node for each of the require() calls.
