slug ¶

The slug filter transforms a given string into another string that only includes safe ASCII characters.

Here is an example:

1
2

{{ 'Wôrķšƥáçè ~~sèťtïñğš~~'|slug }}
Workspace-settings

The default separator between words is a dash (-), but you can
define a selector of your choice by passing it as an argument:

1
2

{{ 'Wôrķšƥáçè ~~sèťtïñğš~~'|slug('/') }}
Workspace/settings

The slugger automatically detects the language of the original string, but you can also specify it explicitly using the second argument:

1

{{ '...'|slug('-', 'ko') }}

The slug filter uses the method by the same name in Symfony's
AsciiSlugger.
