func DetectChromaLexerByFileName ¶

func DetectChromaLexerByFileName(fileName, fileLang string) chroma.Lexer

func RenderCodeByLexer ¶

func RenderCodeByLexer(lexer chroma.Lexer, code string) template.HTML

RenderCodeByLexer returns a HTML version of code string with chroma syntax highlighting classes

func RenderCodeSlowGuess ¶

func RenderCodeSlowGuess(fileName, language, code string) (output template.HTML, lexer chroma.Lexer, lexerDisplayName string)

RenderCodeSlowGuess tries to get a lexer by file name and language first, if not found, it will try to guess the lexer by code content, which is slow (more than several hundreds of milliseconds).

func RenderFullFile ¶

func RenderFullFile(fileName, language string, code []byte) ([]template.HTML, string, error)

func RenderPlainText ¶

func RenderPlainText(code []byte) []template.HTML

RenderPlainText returns non-highlighted HTML for code

func UnsafeSplitHighlightedLines ¶

func UnsafeSplitHighlightedLines(code template.HTML) (ret [][]byte)

UnsafeSplitHighlightedLines splits highlighted code into lines preserving HTML tags It always includes '\n', '\n' can appear at the end of each line or in the middle of HTML tags The '\n' is necessary for copying code from web UI to preserve original code lines ATTENTION: It uses the unsafe conversion between string and []byte for performance reason DO NOT make any modification to the returned [][]byte slice items
