#### caller
|
|
|
|
Figure out your caller (thanks to @substack).
|
|
|
|
##### Initialization Time Caller
|
|
```javascript
|
|
// foo.js
|
|
|
|
var bar = require('bar');
|
|
```
|
|
|
|
```javascript
|
|
// bar.js
|
|
|
|
var caller = require('caller');
|
|
console.log(caller()); // `/path/to/foo.js`
|
|
```
|
|
|
|
##### Runtime Caller
|
|
```javascript
|
|
// foo.js
|
|
|
|
var bar = require('bar');
|
|
bar.doWork();
|
|
```
|
|
|
|
```javascript
|
|
// bar.js
|
|
|
|
var caller = require('caller');
|
|
|
|
exports.doWork = function () {
|
|
console.log(caller()); // `/path/to/foo.js`
|
|
};
|
|
```
|
|
|
|
### Depth
|
|
|
|
Caller also accepts a `depth` argument for tracing back further (defaults to `1`).
|
|
|
|
```javascript
|
|
// foo.js
|
|
|
|
var bar = require('bar');
|
|
bar.doWork();
|
|
```
|
|
|
|
```javascript
|
|
// bar.js
|
|
|
|
var baz = require('baz');
|
|
|
|
exports.doWork = function () {
|
|
baz.doWork();
|
|
};
|
|
```
|
|
|
|
```javascript
|
|
// baz.js
|
|
|
|
var caller = require('caller');
|
|
|
|
exports.doWork = function () {
|
|
console.log(caller(2)); // `/path/to/foo.js`
|
|
};
|
|
```
