urls.Anchorize

Returns the given string, sanitized for usage in an HTML id attribute.

Syntax: urls.Anchorize INPUT
Returns: string
Alias: anchorize

The anchorize and urlize functions are similar:

Use the anchorize function to generate an HTML id attribute value
Use the urlize function to sanitize a string for usage in a URL

For example:

{{ $s := "A B C" }}
{{ $s | anchorize }} → a-b-c
{{ $s | urlize }} → a-b-c

{{ $s := "a b   c" }}
{{ $s | anchorize }} → a-b---c
{{ $s | urlize }} → a-b-c

{{ $s := "< a, b, & c >" }}
{{ $s | anchorize }} → -a-b--c-
{{ $s | urlize }} → a-b-c

{{ $s := "main.go" }}
{{ $s | anchorize }} → maingo
{{ $s | urlize }} → main.go

{{ $s := "Hugö" }}
{{ $s | anchorize }} → hugö
{{ $s | urlize }} → hug%C3%B6

The ursl.Anchorize function sanitizes the resulting string per the autoIDType setting in your project configuration.
