# Writing formatters
|
||
|
|
|
||
|
|
A formatter is a function that accepts *an array of these stylelint result objects* and outputs a string:
|
||
|
|
|
||
|
|
```js
|
||
|
|
// A stylelint result object
|
||
|
|
{
|
||
|
|
source: "path/to/file.css", // The filepath or PostCSS identifier like <input css 1>
|
||
|
|
errored: true, // This is `true` if at least one rule with an "error"-level severity triggered a warning
|
||
|
|
warnings: [ // Array of rule violation warning objects, each like the following ...
|
||
|
|
{
|
||
|
|
line: 3,
|
||
|
|
column: 12,
|
||
|
|
rule: "block-no-empty",
|
||
|
|
severity: "error",
|
||
|
|
text: "You should not have an empty block (block-no-empty)"
|
||
|
|
},
|
||
|
|
..
|
||
|
|
],
|
||
|
|
deprecations: [ // Array of deprecation warning objects, each like the following ...
|
||
|
|
{
|
||
|
|
text: "Feature X has been deprecated and will be removed in the next major version.",
|
||
|
|
reference: "https://stylelint.io/docs/feature-x.md"
|
||
|
|
}
|
||
|
|
],
|
||
|
|
invalidOptionWarnings: [ // Array of invalid option warning objects, each like the following ...
|
||
|
|
{
|
||
|
|
text: "Invalid option X for rule Y",
|
||
|
|
}
|
||
|
|
],
|
||
|
|
ignored: false // This is `true` if the file's path matches a provided ignore pattern
|
||
|
|
}
|
||
|
|
```
|
||
|
