# newline

The `newline` keyword literal represents the [newline control character](https://en.wikipedia.org/wiki/Newline): `\n`. It's useful for navigating or assembling strings.

## Filter support

Besides its natural uses in building strings, `newline` has a special purpose within these string filters:

* [newline\_to\_br](/platform/liquid/filters.md#newline_to_br) – When used with `newline`, this filter will replace instances of `"\r\n"`, and then instances of `"\n"`.
* [replace](/platform/liquid/filters.md#replace-replace_first) – When used with `newline` as its first argument, this filter will replace instances of `"\r\n"`, and then instances of `"\n"`.
* [split](/platform/liquid/filters.md#split) – When used with `newline`, this filter will split by `"\r\n"` when present, and then by `"\n"`.

Under the hood, each of these scenarios uses the regular expression `/\r?\n/`.

## Example

```liquid
{% assign message = "Hello!" | append: newline | append: newline %}
{% assign message = message | append: "This is a new paragraph!" %}

{% capture lines %}
foo
bar
baz
{% endcapture %}

{% assign words = lines | split: newline %}
{% assign tags = lines | replace: newline, ", " %}
```
