|
## Installation |
|
|
|
npm install pug-error |
|
|
|
## Usage |
|
|
|
```js |
|
var error = require('pug-error'); |
|
``` |
|
|
|
### `error(code, message, options)` |
|
|
|
Create a Pug error object. |
|
|
|
`code` is a required unique code for the error type that can be used to pinpoint a certain error. |
|
|
|
`message` is a human-readable explanation of the error. |
|
|
|
`options` can contain any of the following properties: |
|
|
|
- `filename`: the name of the file causing the error |
|
- `line`: the offending line |
|
- `column`: the offending column |
|
- `src`: the Pug source, if available, for pretty-printing the error context |
|
|
|
The resulting error object is a simple Error object with additional properties given in the arguments. |
|
|
|
**Caveat:** the `message` argument is stored in `err.msg`, not `err.message`, which is occupied with a better-formatted message. |
|
|
|
```js |
|
var error = require('pug-error'); |
|
|
|
var err = error('MY_CODE', 'My message', {line: 3, filename: 'myfile', src: 'foo\nbar\nbaz\nbash\nbing'}); |
|
// { code: 'PUG:MY_CODE', |
|
// msg: 'My message', |
|
// line: 3, |
|
// column: undefined, |
|
// filename: 'myfile', |
|
// src: 'foo\nbar\nbaz\nbash\nbing', |
|
// message: 'myfile:3\n 1| foo\n 2| bar\n > 3| baz\n 4| bash\n 5| bing\n\nMy message' } |
|
|
|
throw err; |
|
``` |
