# Markdown Parser and HTML Renderer for Go
[![GoDoc](https://godoc.org/github.com/gomarkdown/markdown?status.svg)](https://godoc.org/github.com/gomarkdown/markdown) [![codecov](https://codecov.io/gh/gomarkdown/markdown/branch/master/graph/badge.svg)](https://codecov.io/gh/gomarkdown/markdown)
Package `github.com/gomarkdown/markdown` is a very fast Go library for parsing [Markdown](https://daringfireball.net/projects/markdown/) documents and rendering them to HTML.
It's fast and supports common extensions.
## Installation
go get -u github.com/gomarkdown/markdown
API Docs:
- https://godoc.org/github.com/gomarkdown/markdown : top level package
- https://godoc.org/github.com/gomarkdown/markdown/ast : defines abstract syntax tree of parsed markdown document
- https://godoc.org/github.com/gomarkdown/markdown/parser : parser
- https://godoc.org/github.com/gomarkdown/markdown/html : html renderer
## Usage
To convert markdown text to HTML using reasonable defaults:
```go
md := []byte("## markdown document")
output := markdown.ToHTML(md, nil, nil)
```
## Customizing markdown parser
Markdown format is loosely specified and there are multiple extensions invented after original specification was created.
The parser supports several [extensions](https://godoc.org/github.com/gomarkdown/markdown/parser#Extensions).
Default parser uses most common `parser.CommonExtensions` but you can easily use parser with custom extension:
```go
import (
"github.com/gomarkdown/markdown"
"github.com/gomarkdown/markdown/parser"
)
extensions := parser.CommonExtensions | parser.AutoHeadingIDs
parser := parser.NewWithExtensions(extensions)
md := []byte("markdown text")
html := markdown.ToHTML(md, parser, nil)
```
## Customizing HTML renderer
Similarly, HTML renderer can be configured with different [options](https://godoc.org/github.com/gomarkdown/markdown/html#RendererOptions)
Here's how to use a custom renderer:
```go
import (
"github.com/gomarkdown/markdown"
"github.com/gomarkdown/markdown/html"
)
htmlFlags := html.CommonFlags | html.HrefTargetBlank
opts := html.RendererOptions{Flags: htmlFlags}
renderer := html.NewRenderer(opts)
md := []byte("markdown text")
html := markdown.ToHTML(md, nil, renderer)
```
HTML renderer also supports reusing most of the logic and overriding rendering of only specifc nodes.
You can provide [RenderNodeFunc](https://godoc.org/github.com/gomarkdown/markdown/html#RenderNodeFunc) in [RendererOptions](https://godoc.org/github.com/gomarkdown/markdown/html#RendererOptions).
The function is called for each node in AST, you can implement custom rendering logic and tell HTML renderer to skip rendering this node.
Here's the simplest example that drops all code blocks from the output:
````go
import (
"github.com/gomarkdown/markdown"
"github.com/gomarkdown/markdown/ast"
"github.com/gomarkdown/markdown/html"
)
// return (ast.GoToNext, true) to tell html renderer to skip rendering this node
// (because you've rendered it)
func renderHookDropCodeBlock(w io.Writer, node ast.Node, entering bool) (ast.WalkStatus, bool) {
// skip all nodes that are not CodeBlock nodes
if _, ok := node.(*ast.CodeBlock); !ok {
return ast.GoToNext, false
}
// custom rendering logic for ast.CodeBlock. By doing nothing it won't be
// present in the output
return ast.GoToNext, true
}
opts := html.RendererOptions{
Flags: html.CommonFlags,
RenderNodeHook: renderHookDropCodeBlock,
}
renderer := html.NewRenderer(opts)
md := "test\n```\nthis code block will be dropped from output\n```\ntext"
html := markdown.ToHTML([]byte(s), nil, renderer)
````
## Sanitize untrusted content
We don't protect against malicious content. When dealing with user-provided
markdown, run renderer HTML through HTML sanitizer such as [Bluemonday](https://github.com/microcosm-cc/bluemonday).
Here's an example of simple usage with Bluemonday:
```go
import (
"github.com/microcosm-cc/bluemonday"
"github.com/gomarkdown/markdown"
)
// ...
maybeUnsafeHTML := markdown.ToHTML(md, nil, nil)
html := bluemonday.UGCPolicy().SanitizeBytes(maybeUnsafeHTML)
```
## mdtohtml command-line tool
https://github.com/gomarkdown/mdtohtml is a command-line markdown to html
converter built using this library.
You can also use it as an example of how to use the library.
You can install it with:
go get -u github.com/gomarkdown/mdtohtml
To run: `mdtohtml input-file [output-file]`
## Features
- **Compatibility**. The Markdown v1.0.3 test suite passes with
the `--tidy` option. Without `--tidy`, the differences are
mostly in whitespace and entity escaping, where this package is
more consistent and cleaner.
- **Common extensions**, including table support, fenced code
blocks, autolinks, strikethroughs, non-strict emphasis, etc.
- **Safety**. Markdown is paranoid when parsing, making it safe
to feed untrusted user input without fear of bad things
happening. The test suite stress tests this and there are no
known inputs that make it crash. If you find one, please let me
know and send me the input that does it.
NOTE: "safety" in this context means _runtime safety only_. In order to
protect yourself against JavaScript injection in untrusted content, see
[this example](https://github.com/gomarkdown/markdown#sanitize-untrusted-content).
- **Fast**. It is fast enough to render on-demand in
most web applications without having to cache the output.
- **Thread safety**. You can run multiple parsers in different
goroutines without ill effect. There is no dependence on global
shared state.
- **Minimal dependencies**. Only depends on standard library packages in Go.
- **Standards compliant**. Output successfully validates using the
W3C validation tool for HTML 4.01 and XHTML 1.0 Transitional.
## Extensions
In addition to the standard markdown syntax, this package
implements the following extensions:
- **Intra-word emphasis supression**. The `_` character is
commonly used inside words when discussing code, so having
markdown interpret it as an emphasis command is usually the
wrong thing. We let you treat all emphasis markers as
normal characters when they occur inside a word.
- **Tables**. Tables can be created by drawing them in the input
using a simple syntax:
```
Name | Age
--------|------
Bob | 27
Alice | 23
```
Table footers are supported as well and can be added with equal signs (`=`):
```
Name | Age
--------|------
Bob | 27
Alice | 23
========|======
Total | 50
```
- **Fenced code blocks**. In addition to the normal 4-space
indentation to mark code blocks, you can explicitly mark them
and supply a language (to make syntax highlighting simple). Just
mark it like this:
```go
func getTrue() bool {
return true
}
```
You can use 3 or more backticks to mark the beginning of the
block, and the same number to mark the end of the block.
- **Definition lists**. A simple definition list is made of a single-line
term followed by a colon and the definition for that term.
Cat
: Fluffy animal everyone likes
Internet
: Vector of transmission for pictures of cats
Terms must be separated from the previous definition by a blank line.
- **Footnotes**. A marker in the text that will become a superscript number;
a footnote definition that will be placed in a list of footnotes at the
end of the document. A footnote looks like this:
This is a footnote.[^1]
[^1]: the footnote text.
- **Autolinking**. We can find URLs that have not been
explicitly marked as links and turn them into links.
- **Strikethrough**. Use two tildes (`~~`) to mark text that
should be crossed out.
- **Hard line breaks**. With this extension enabled newlines in the input
translate into line breaks in the output. This extension is off by default.
- **Non blocking space**. With this extension enabled spaces preceeded by an backslash n the input
translate non-blocking spaces in the output. This extension is off by default.
- **Smart quotes**. Smartypants-style punctuation substitution is
supported, turning normal double- and single-quote marks into
curly quotes, etc.
- **LaTeX-style dash parsing** is an additional option, where `--`
is translated into `&ndash;`, and `---` is translated into
`&mdash;`. This differs from most smartypants processors, which
turn a single hyphen into an ndash and a double hyphen into an
mdash.
- **Smart fractions**, where anything that looks like a fraction
is translated into suitable HTML (instead of just a few special
cases like most smartypant processors). For example, `4/5`
becomes `<sup>4</sup>&frasl;<sub>5</sub>`, which renders as
<sup>4</sup>&frasl;<sub>5</sub>.
- **MathJaX Support** is an additional feature which is supported by
many markdown editor. It translate inline math equation quoted by `$`
and display math block quoted by `$$` into MathJax compatible format.
hyphen `_` won't break LaTeX render within a math element any more.
```
$$
\left[ \begin{array}{a} a^l_1 \\ ⋮ \\ a^l_{d_l} \end{array}\right]
= \sigma(
\left[ \begin{matrix}
w^l_{1,1} & ⋯ & w^l_{1,d_{l-1}} \\
⋮ & ⋱ & ⋮ \\
w^l_{d_l,1} & ⋯ & w^l_{d_l,d_{l-1}} \\
\end{matrix}\right] ·
\left[ \begin{array}{x} a^{l-1}_1 \\ ⋮ \\ ⋮ \\ a^{l-1}_{d_{l-1}} \end{array}\right] +
\left[ \begin{array}{b} b^l_1 \\ ⋮ \\ b^l_{d_l} \end{array}\right])
$$
```
- **Ordered list start number**. With this extension enabled an ordered list will start with the
the number that was used to start it.
- **Super and subscript**. With this extension enabled sequences between ^ will indicate
superscript and ~ will become a subscript. For example: H~2~O is a liquid, 2^10^ is 1024.
- **Block level attributes**, allow setting attributes (ID, classes and key/value pairs) on block
level elements. The attribute must be enclosed with braces and be put on a line before the
element.
```
{#id3 .myclass fontsize="tiny"}
# Header 1
```
Will convert into `<h1 id="id3" class="myclass" fontsize="tiny">Header 1</h1>`.
- **Mmark support**, see <https://mmark.nl/syntax> for all new syntax elements this adds.
## Todo
- port https://github.com/russross/blackfriday/issues/348
- port [LaTeX output](https://github.com/Ambrevar/Blackfriday-LaTeX):
renders output as LaTeX.
- port https://github.com/shurcooL/github_flavored_markdown to markdown
- port [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt,
but for markdown.
- More unit testing
- Improve unicode support. It does not understand all unicode
rules (about what constitutes a letter, a punctuation symbol,
etc.), so it may fail to detect word boundaries correctly in
some instances. It is safe on all utf-8 input.
## History
markdown is a fork of v2 of https://github.com/russross/blackfriday that is:
- actively maintained (sadly in Feb 2018 blackfriday was inactive for 5 months with many bugs and pull requests accumulated)
- refactored API (split into ast/parser/html sub-packages)
Blackfriday itself was based on C implementation [sundown](https://github.com/vmg/sundown) which in turn was based on [libsoldout](http://fossil.instinctive.eu/libsoldout/home).

## Changes from blackfriday
This library is derived from blackfriday library. Here's a list of changes.
**Redesigned API**
- split into 3 separate packages: ast, parser and html (for html renderer). This makes the API more manageable. It also separates e.g. parser option from renderer options
- changed how AST node is represented from union-like representation (manually keeping track of the type of the node) to using interface{} (which is a Go way to combine an arbitrary value with its type)
**Allow re-using most of html renderer logic**
You can implement your own renderer by implementing `Renderer` interface.
Implementing a full renderer is a lot of work and often you just want to tweak html rendering of few node typs.
I've added a way to hook `Renderer.Render` function in html renderer with a custom function that can take over rendering of specific nodes.
I use it myself to do syntax-highlighting of code snippets.
**Speed up go test**
Running `go test` was really slow (17 secs) because it did a poor man's version of fuzzing by feeding the parser all subsets of test strings in order to find panics
due to incorrect parsing logic.
I've moved that logic to `cmd/crashtest`, so that it can be run on CI but not slow down regular development.
Now `go test` is blazing fast.

Package markdown implements markdown parser and HTML renderer.
It parses markdown into AST format which can be serialized to HTML
(using html.Renderer) or possibly other formats (using alternate renderers).
Convert markdown to HTML
The simplest way to convert markdown document to HTML
md := []byte("## markdown document")
html := markdown.ToHTML(md, nil, nil)
Customizing parsing and HTML rendering
You can customize parser and HTML renderer:
import (
"github.com/gomarkdown/markdown/parser"
"github.com/gomarkdown/markdown/renderer"
"github.com/gomarkdown/markdown"
)
extensions := parser.CommonExtensions | parser.AutoHeadingIDs
p := parser.NewWithExensions(extensions)
htmlFlags := html.CommonFlags | html.HrefTargetBlank
opts := html.RendererOptions{Flags: htmlFlags}
renderer := html.NewRenderer(opts)
md := []byte("markdown text")
html := markdown.ToHTML(md, p, renderer)

Package html implements HTML renderer of parsed markdown document.
Configuring and customizing a renderer
A renderer can be configured with multiple options:
import "github.com/gomarkdown/markdown/html"
flags := html.CommonFlags | html.CompletePage | html.HrefTargetBlank
opts := html.RenderOptions{
TItle: "A custom title",
Flags: flags,
}
renderer := html.NewRenderer(opts)
You can also re-use most of the logic and customize rendering of selected nodes
by providing node render hook.
This is most useful for rendering nodes that allow for design choices, like
links or code blocks.
import (
"github.com/gomarkdown/markdown/html"
"github.com/gomarkdown/markdown/ast"
)
// a very dummy render hook that will output "code_replacements" instead of
// <code>${content}</code> emitted by html.Renderer
func renderHookCodeBlock(w io.Writer, node *ast.Node, entering bool) (ast.WalkStatus, bool) {
_, ok := node.Data.(*ast.CodeBlockData)
if !ok {
return ast.GoToNext, false
}
io.WriteString(w, "code_replacement")
return ast.GoToNext, true
}
opts := html.RendererOptions{
RenderNodeHook: renderHookCodeBlock,
}
renderer := html.NewRenderer(opts)
*/

# Things to do
[ ] docs: add examples like https://godoc.org/github.com/dgrijalva/jwt-go (put in foo_example_test.go). Or see https://github.com/garyburd/redigo/blob/master/redis/zpop_example_test.go#L5 / https://godoc.org/github.com/garyburd/redigo/redis or https://godoc.org/github.com/go-redis/redis
[ ] figure out expandTabs and parser.TabSizeEight. Are those used?
[ ] SoftbreakData is not used

========
Package golang-commonmark/markdown provides a CommonMark-compliant markdown parser and renderer, written in Go.
## Installation
go get -u gitlab.com/golang-commonmark/markdown
You can also go get [mdtool](https://gitlab.com/golang-commonmark/mdtool), an example command-line tool:
go get -u gitlab.com/golang-commonmark/mdtool
## Standards support
Currently supported CommonMark spec: [v0.28](http://spec.commonmark.org/0.28/).
## Extensions
Besides the features required by CommonMark, golang-commonmark/markdown supports:
* Tables (GFM)
* Strikethrough (GFM)
* Autoconverting plain-text URLs to links
* Typographic replacements (smart quotes and other)
## Usage
``` go
md := markdown.New(markdown.XHTMLOutput(true))
fmt.Println(md.RenderToString([]byte("Header\n===\nText")))
```
Check out [the source of mdtool](https://gitlab.com/golang-commonmark/mdtool/blob/master/main.go) for a more complete example.
The following options are currently supported:
Name | Type | Description | Default
--------------- | --------- | ----------------------------------------------------------- | ---------
HTML | bool | whether to enable raw HTML | false
Tables | bool | whether to enable GFM tables | true
Linkify | bool | whether to autoconvert plain-text URLs to links | true
Typographer | bool | whether to enable typographic replacements | true
Quotes | string / []string | double + single quote replacement pairs for the typographer | “”‘’
MaxNesting | int | maximum nesting level | 20
LangPrefix | string | CSS language prefix for fenced blocks | language-
Breaks | bool | whether to convert newlines inside paragraphs into `<br>` | false
XHTMLOutput | bool | whether to output XHTML instead of HTML | false
