## 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()`.
|
||
|
|
||
|
## var found = detective.find(src, opts)
|
||
|
|
||
|
Give some source body `src`, return `found` with:
|
||
|
|
||
|
* `found.strings` - an array of each string found in a `require()`
|
||
|
* `found.expressions` - an array of each stringified expression found in a
|
||
|
`require()` call
|
||
|
* `found.nodes` (when `opts.nodes === true`) - an array of AST nodes for each
|
||
|
argument found in a `require()` call
|
||
|
|
||
|
Optionally:
|
||
|
|
||
|
* `opts.word` - specify a different function name instead of `"require"`
|
||
|
* `opts.nodes` - when `true`, populate `found.nodes`
|
||
|
* `opts.isRequire(node)` - a function returning whether an AST `CallExpression`
|
||
|
node is a require call
|
||
|
* `opts.parse` - supply options directly to
|
||
|
[acorn](https://npmjs.org/package/acorn) with some support for esprima-style
|
||
|
options `range` and `loc`
|
||
|
* `opts.ecmaVersion` - default: 9
