func NormalizeChart ¶

func NormalizeChart(repo string) string

NormalizeChart normalizes a chart repository URL for purposes of comparison. Crucially, this function removes the oci:// prefix from the URL if there is one.

func NormalizeGit ¶

func NormalizeGit(repo string) string

NormalizeGit normalizes Git URLs of the following forms:

• http[s]://[proxy-user:proxy-pass@]host.xz[:port][/path/to/repo[.git][/]]
• ssh://[user@]host.xz[:port][/path/to/repo[.git][/]]
• [user@]host.xz[:path/to/repo[.git][/]]

This is useful for the purposes of comparison and also in cases where a canonical representation of a Git URL is needed. Any URL that cannot be normalized will be returned as-is.

func NormalizeImage ¶

func NormalizeImage(repoURL string) string

NormalizeImage normalizes image repository URLs. Notably, hostnames docker.io and index.docker.io, if present, are dropped. The optional /library prefix for official images from Docker Hub, if included, is also dropped. Valid, non-Docker Hub repository URLs will be returned unchanged.

This is useful for the purposes of comparison and also in cases where a canonical representation of a repository URL is needed. Any URL that cannot be normalized will be returned as-is.

func SanitizeURL ¶ added in v1.9.3

func SanitizeURL(url string) string

SanitizeURL removes leading and trailing whitespace only from a string presumed to represent a URL. It additionally removes non-printable runes such as byte order marks (BOMs) from anywhere in a string. Leading whitespace and non-printable runes can easily be copied and pasted without a user realizing and are known to interfere with URL parsing.
