Create [vfile][] messages.
## Install
[npm][]:
```bash
npm install vfile-message
```
## Use
```js
var VMessage = require('vfile-message')
var message = new VMessage(
'`braavo` is misspelt; did you mean `bravo`?',
{line: 1, column: 8},
'spell:typo'
)
console.log(message)
```
Yields:
```js
{ [1:8: `braavo` is misspelt; did you mean `bravo`?]
reason: '`braavo` is misspelt; did you mean `bravo`?',
fatal: null,
line: 1,
column: 8,
location:
{ start: { line: 1, column: 8 },
end: { line: null, column: null } },
source: 'spell',
ruleId: 'typo' }
```
## API
### `VMessage(reason[, position][, origin])`
Constructor of a message for `reason` at `position` from `origin`.
When an error is passed in as `reason`, copies the stack.
##### Parameters
###### `reason`
Reason for message (`string` or `Error`).
Uses the stack and message of the error if given.
###### `position`
Place at which the message occurred in a file ([`Node`][node],
[`Position`][position], or [`Point`][point], optional).
###### `origin`
Place in code the message originates from (`string`, optional).
Can either be the [`ruleId`][ruleid] (`'rule'`), or a string with both a
[`source`][source] and a [`ruleId`][ruleid] delimited with a colon
(`'source:rule'`).
##### Extends
[`Error`][error].
##### Returns
An instance of itself.
##### Properties
###### `reason`
Reason for message (`string`).
###### `fatal`
If `true`, marks associated file as no longer processable (`boolean?`).
If `false`, necessitates a (potential) change.
The value can also be `null` or `undefined`.
###### `line`
Starting line of error (`number?`).
###### `column`
Starting column of error (`number?`).
###### `location`
Full range information, when available ([`Position`][position]).
Has `start` and `end` properties, both set to an object with `line` and
`column`, set to `number?`.
###### `source`
Namespace of warning (`string?`).
###### `ruleId`
Category of message (`string?`).
###### `stack`
Stack of message (`string?`).
##### Custom properties
Its OK to store custom data directly on the `VMessage`, some of those are
handled by [utilities][util].
###### `file`
You may add a `file` property with a path of a file (used throughout the
[**VFile**][vfile] ecosystem).
###### `note`
You may add a `note` property with a long form description of the message
(supported by [`vfile-reporter`][reporter]).
###### `url`
You may add a `url` property with a link to documentation for the message.
