# 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 `–`, and `---` is translated into
|
||||
`—`. 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>⁄<sub>5</sub>`, which renders as
|
||||
<sup>4</sup>⁄<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
|

}
|

[ ] 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?
|
||||
|

markdown [![GoDoc](http://godoc.org/gitlab.com/golang-commonmark/markdown?status.svg)](http://godoc.org/gitlab.com/golang-commonmark/markdown) [![License](https://img.shields.io/badge/licence-BSD--2--Clause-blue.svg)](https://opensource.org/licenses/BSD-2-Clause) [![Pipeline status](https://gitlab.com/golang-commonmark/markdown/badges/master/pipeline.svg)](https://gitlab.com/golang-commonmark/markdown/commits/master) [![Coverage report](https://gitlab.com/golang-commonmark/markdown/badges/master/coverage.svg)](https://gitlab.com/golang-commonmark/markdown/commits/master)
|
||||
========
|
||||
|
||||
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
|
||||
|
||||
