func CamoEncode(link string) string

CamoEncode encodes a lnk to fit with the go-camo and camo proxy links. The purposes of camo-proxy are: 1. Allow accessing "http://" images on a HTTPS site by using the "https://" URLs provided by camo-proxy. 2. Hide the visitor's real IP (protect privacy) when accessing external images.

func CustomLinkURLSchemes

func CustomLinkURLSchemes(schemes []string)

CustomLinkURLSchemes allows for additional schemes to be detected when parsing links within text

func DetectRendererType

func DetectRendererType(filename string, input io.Reader) string

DetectRendererType detects the markup type of the content

func Init

func Init(ph *ProcessorHelper)

Init initialize regexps for markdown parsing

func InitializeSanitizer

func InitializeSanitizer()

InitializeSanitizer (re)initializes the current sanitizer to account for changes in settings

func IsErrUnsupportedRenderExtension

func IsErrUnsupportedRenderExtension(err error) bool
func IsLink(link []byte) bool

IsLink reports whether link fits valid format.

func IsMarkupFile

func IsMarkupFile(name, markup string) bool

IsMarkupFile reports whether file is a markup type file

func IsSameDomain

func IsSameDomain(s string) bool

IsSameDomain checks if given url string has the same hostname as current Gitea instance

func NewSanitizer

func NewSanitizer()

NewSanitizer initializes sanitizer with allowed attributes based on settings. Multiple calls to this function will only create one instance of Sanitizer during entire application lifecycle.

func PostProcess

func PostProcess(
	ctx *RenderContext,
	input io.Reader,
	output io.Writer,
) error

func RenderCommitMessageSubject

func RenderCommitMessageSubject(
	ctx *RenderContext,
	content string,
) (string, error)

RenderCommitMessageSubject will use the same logic as PostProcess and RenderCommitMessage, but will disable the shortLinkProcessor and emailAddressProcessor, will add a defaultLinkProcessor if defaultLink is set, which changes every text node into a link to the passed default link.

func RenderDescriptionHTML

func RenderDescriptionHTML(
	ctx *RenderContext,
	content string,
) (string, error)
