# detective
find all calls to `require()` by walking the AST
[](http://travis-ci.org/substack/node-detective)
# example
## strings
strings_src.js:
``` js
var a = require('a');
var b = require('b');
var c = require('c');
```
strings.js:
``` js
var detective = require('detective');
var fs = require('fs');
var src = fs.readFileSync(__dirname + '/strings_src.js');
var requires = detective(src);
console.dir(requires);
```
output:
```
$ node examples/strings.js
[ 'a', 'b', 'c' ]
```
# methods
``` js
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.
