func IsReadmeFile

func IsReadmeFile(name string) bool

IsReadmeFile reports whether name looks like a README file based on its name.

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(rawHTML []byte, urlPrefix string, metas map[string]string, isWikiMarkdown bool) []byte

PostProcess treats different types of HTML differently, and only renders special links for plain text blocks.

func Render

func Render(rawBytes []byte, urlPrefix string, metas map[string]string) []byte

Render renders Markdown to HTML with all specific handling stuff.

func RenderCrossReferenceIssueIndexPattern

func RenderCrossReferenceIssueIndexPattern(rawBytes []byte, urlPrefix string, metas map[string]string) []byte

RenderCrossReferenceIssueIndexPattern renders issue indexes from other repositories to corresponding links.

func RenderIssueIndexPattern

func RenderIssueIndexPattern(rawBytes []byte, urlPrefix string, metas map[string]string) []byte

RenderIssueIndexPattern renders issue indexes to corresponding links.

func RenderRaw

func RenderRaw(body []byte, urlPrefix string, wikiMarkdown bool) []byte

RenderRaw renders Markdown to HTML without handling special links.

func RenderShortLinks

func RenderShortLinks(rawBytes []byte, urlPrefix string, noLink bool, isWikiMarkdown bool) []byte

RenderShortLinks processes [[syntax]]

noLink flag disables making link tags when set to true so this function just replaces the whole [[...]] with the content text

isWikiMarkdown is a flag to choose linking url prefix

func RenderSpecialLink

func RenderSpecialLink(rawBytes []byte, urlPrefix string, metas map[string]string, isWikiMarkdown bool) []byte

RenderSpecialLink renders mentions, indexes and SHA1 strings to corresponding links.

func RenderString

func RenderString(raw, urlPrefix string, metas map[string]string) string

RenderString renders Markdown to HTML with special links and returns string type.

func RenderWiki

func RenderWiki(rawBytes []byte, urlPrefix string, metas map[string]string) string

RenderWiki renders markdown wiki page to HTML and return HTML string

func Sanitize

func Sanitize(s string) string

Sanitize takes a string that contains a HTML fragment or document and applies policy whitelist.

func SanitizeBytes

func SanitizeBytes(b []byte) []byte

SanitizeBytes takes a []byte slice that contains a HTML fragment or document and applies policy whitelist.

func URLJoin

func URLJoin(elem ...string) string

URLJoin joins url components, like path.Join, but preserving contents
