Slugify

Transform strings from any language into slugs.

It works by transliterating Unicode characters into alphanumeric strings (e.g. 字 into zi). All punctuation is stripped and whitespace between words are replaced by hyphens.

This package has no dependencies.

Examples

Slug.slugify("Hello, World!")
"hello-world"

Slug.slugify("你好，世界")
"nihaoshijie"

Slug.slugify("Wikipedia case", separator: ?_, lowercase: false)
"Wikipedia_case"

# Remember to check for nil if a valid slug is important!
Slug.slugify("🙅‍")
nil

Options

Whitespaces are replaced by separators (defaults to -). Pass any codepoint or string to customize the separator, or pass "" to have none.

Slug.slugify("  How are   you?  ")
"how-are-you"

Slug.slugify("John Doe", separator: ?.)
"john.doe"

Slug.slugify("Wide open spaces", separator: "%20")
"wide%20open%20spaces"

Slug.slugify("Madam, I'm Adam", separator: "")
"madamimadam"

Slugs are forced lowercase by default, unless lowercase: false is passed.

Slug.slugify("StUdLy CaPs", lowercase: false)
"StUdLy-CaPs"

Set truncate so slugs don‘t exceed a certain length. They are trimmed to the closest word, as delimited by separators.

Slug.slugify("Call Me Maybe", truncate: 7)
"call-me"

Slug.slugify("Call Me Maybe", truncate: 10)
"call-me"

To avoid transforming certain characters, pass a string (or a list of strings) of graphemes to ignore.

Slug.slugify("你好，世界", ignore: "你好")
"你好shijie"

Slug.slugify("你好，世界", ignore: ["你", "好"])
"你好shijie"

Caveats

Slugify cannot differentiate between Chinese characters and Japanese Kanji. In the same vein as other libraries, Japanese Kanji will transform into Chinese pinyin.
