Installation
|
||||
------------
|
||||
|
||||
Blackfriday is compatible with Go 1. If you are using an older
|
||||
release of Go, consider using v1.1 of blackfriday, which was based
|
||||
on the last stable release of Go prior to Go 1. You can find it as a
|
||||
tagged commit on github.
|
||||
Blackfriday is compatible with any modern Go release. With Go and git installed:

||||

||||
With Go 1 and git installed:

will download, compile, and install the package into your `$GOPATH`
|
||||
directory hierarchy. Alternatively, you can achieve the same if you
|
||||
import it into a project:
|
||||
|
||||
import "github.com/russross/blackfriday"
|
||||
Versions
|
||||
--------
|
||||
|
||||
Currently maintained and recommended version of Blackfriday is `v2`. It's being
|
||||
developed on its own branch: https://github.com/russross/blackfriday/tree/v2 and the
|
||||
documentation is available at
|
||||
https://godoc.org/gopkg.in/russross/blackfriday.v2.
|
||||
|
||||
It is `go get`-able via [gopkg.in][6] at `gopkg.in/russross/blackfriday.v2`,
|
||||
but we highly recommend using package management tool like [dep][7] or
|
||||
[Glide][8] and make use of semantic versioning. With package management you
|
||||
should import `github.com/russross/blackfriday` and specify that you're using
|
||||
version 2.0.0.
|
||||
|
||||
Version 2 offers a number of improvements over v1:
|
||||
|
||||
* Cleaned up API
|
||||
* A separate call to [`Parse`][4], which produces an abstract syntax tree for
|
||||
the document
|
||||
* Latest bug fixes
|
||||
* Flexibility to easily add your own rendering extensions
|
||||
|
||||
Potential drawbacks:
|
||||
|
||||
* Our benchmarks show v2 to be slightly slower than v1. Currently in the
|
||||
ballpark of around 15%.
|
||||
* API breakage. If you can't afford modifying your code to adhere to the new API
|
||||
and don't care too much about the new features, v2 is probably not for you.
|
||||
* Several bug fixes are trailing behind and still need to be forward-ported to
|
||||
v2. See issue [#348](https://github.com/russross/blackfriday/issues/348) for
|
||||
tracking.
|
||||
|
||||
If you are still interested in the legacy `v1`, you can import it from
|
||||
`github.com/russross/blackfriday`. Documentation for the legacy v1 can be found
|
||||
here: https://godoc.org/github.com/russross/blackfriday
|
||||
|
||||
### Known issue with `dep`
|
||||
|
||||
There is a known problem with using Blackfriday v1 _transitively_ and `dep`.
|
||||
Currently `dep` prioritizes semver versions over anything else, and picks the
|
||||
latest one, plus it does not apply a `[[constraint]]` specifier to transitively
|
||||
pulled in packages. So if you're using something that uses Blackfriday v1, but
|
||||
that something does not use `dep` yet, you will get Blackfriday v2 pulled in and
|
||||
your first dependency will fail to build.
|
||||
|
||||
There are couple of fixes for it, documented here:
|
||||
https://github.com/golang/dep/blob/master/docs/FAQ.md#how-do-i-constrain-a-transitive-dependencys-version
|
||||
|
||||
Meanwhile, `dep` team is working on a more general solution to the constraints
|
||||
on transitive dependencies problem: https://github.com/golang/dep/issues/1124.

Usage

|
||||
output := blackfriday.MarkdownCommon(input)
|
||||
|
||||
### v2
|
||||
|
||||
For the most sensible markdown processing, it is as simple as getting your input
|
||||
into a byte slice and calling:
|
||||
|
||||
```go
|
||||
output := blackfriday.Run(input)
|
||||
```
|
||||
|
||||
Your input will be parsed and the output rendered with a set of most popular
|
||||
extensions enabled. If you want the most basic feature set, corresponding with
|
||||
the bare Markdown specification, use:
|
||||
|
||||
```go
|
||||
output := blackfriday.Run(input, blackfriday.WithNoExtensions())
|
||||
```
|
||||
|
||||
### Sanitize untrusted content
|
||||
|
||||
Blackfriday itself does nothing to protect against malicious content. If you are
|
||||
dealing with user-supplied markdown, we recommend running blackfriday's output
|
||||
through HTML sanitizer such as
|
||||
[Bluemonday](https://github.com/microcosm-cc/bluemonday).

### Sanitized anchor names
|
||||
|
||||
Blackfriday includes an algorithm for creating sanitized anchor names
|
||||
corresponding to a given input text. This algorithm is used to create
|
||||
anchors for headings when `EXTENSION_AUTO_HEADER_IDS` is enabled. The
|
||||
algorithm has a specification, so that other packages can create
|
||||
compatible anchor names and links to those anchors.
|
||||
|
||||
The specification is located at https://godoc.org/github.com/russross/blackfriday#hdr-Sanitized_Anchor_Names.
|
||||
|
||||
[`SanitizedAnchorName`](https://godoc.org/github.com/russross/blackfriday#SanitizedAnchorName) exposes this functionality, and can be used to
|
||||
create compatible links to the anchor names generated by blackfriday.
|
||||
This algorithm is also implemented in a small standalone package at
|
||||
[`github.com/shurcooL/sanitized_anchor_name`](https://godoc.org/github.com/shurcooL/sanitized_anchor_name). It can be useful for clients
|
||||
that want a small package and don't need full functionality of blackfriday.
