Overview

This package implements a parser for the subset of the CommonMark spec necessary for us to do server-side processing. It is not a full implementation and lacks many features. But it is complete enough to efficiently and accurately allow us to do what we need to like rewrite image URLs for proxying.

Functions

func CharacterReference

func CharacterReference(ref string) string

func Inspect

func Inspect(markdown string, f func(interface{}) bool)

Inspect traverses the markdown tree in depth-first order. If f returns true, Inspect invokes f recursively for each child of the block or inline, followed by a call of f(nil).

func InspectBlock

func InspectBlock(block Block, f func(Block) bool)

InspectBlock traverses the blocks in depth-first order, starting with block. If f returns true, InspectBlock invokes f recursively for each child of the block, followed by a call of f(nil).

func InspectInline

func InspectInline(inline Inline, f func(Inline) bool)

InspectInline traverses the blocks in depth-first order, starting with block. If f returns true, InspectInline invokes f recursively for each child of the block, followed by a call of f(nil).

func Parse

func Parse(markdown string) (*Document, []*ReferenceDefinition)

func ParseBlocks

func ParseBlocks(markdown string, lines []Line) (*Document, []*ReferenceDefinition)

func RenderBlockHTML

func RenderBlockHTML(block Block, referenceDefinitions []*ReferenceDefinition) (result string)

func RenderHTML

func RenderHTML(markdown string) string

RenderHTML produces HTML with the same behavior as the example renderer used in the CommonMark reference materials except for one slight difference: for brevity, no unnecessary whitespace is inserted between elements. The output is not defined by the CommonMark spec, and it exists primarily as an aid in testing.

func RenderInlineHTML

func RenderInlineHTML(inline Inline) (result string)

func Unescape

func Unescape(markdown string) string
