It -is paranoid about its input (so you can safely feed it user-supplied -data), it is fast, it supports common extensions (tables, smart -punctuation substitutions, etc.), and it is safe for all utf-8 -(unicode) input. - -HTML output is currently supported, along with Smartypants -extensions. - -It started as a translation from C of [Sundown][3]. - - -Installation ------------- - -Blackfriday is compatible with any modern Go release. With Go and git installed: - - go get -u gopkg.in/russross/blackfriday.v2 - -will download, compile, and install the package into your `$GOPATH` directory -hierarchy. - - -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 ------ - -### v1 - -For basic usage, it is as simple as getting your input into a byte -slice and calling: - - output := blackfriday.MarkdownBasic(input) - -This renders it with no extensions enabled. To get a more useful -feature set, use this instead: - - 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][5]. - -Here's an example of simple usage of Blackfriday together with Bluemonday: - -```go -import ( - "github.com/microcosm-cc/bluemonday" - "gopkg.in/russross/blackfriday.v2" -) - -// ... -unsafe := blackfriday.Run(input) -html := bluemonday.UGCPolicy().SanitizeBytes(unsafe) -``` - -### Custom options, v1 - -If you want to customize the set of options, first get a renderer -(currently only the HTML output engine), then use it to -call the more general `Markdown` function. For examples, see the -implementations of `MarkdownBasic` and `MarkdownCommon` in -`markdown.go`. - -### Custom options, v2 - -If you want to customize the set of options, use `blackfriday.WithExtensions`, -`blackfriday.WithRenderer` and `blackfriday.WithRefOverride`. - -### `blackfriday-tool` - -You can also check out `blackfriday-tool` for a more complete example -of how to use it. Download and install it using: - - go get github.com/russross/blackfriday-tool - -This is a simple command-line tool that allows you to process a -markdown file using a standalone program. You can also browse the -source directly on github if you are just looking for some example -code: - -* - -Note that if you have not already done so, installing -`blackfriday-tool` will be sufficient to download and install -blackfriday in addition to the tool itself. The tool binary will be -installed in `$GOPATH/bin`. This is a statically-linked binary that -can be copied to wherever you need it without worrying about -dependencies and library versions. - -### 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. - - -Features --------- - -All features of Sundown are supported, including: - -* **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 blackfriday is - more consistent and cleaner. - -* **Common extensions**, including table support, fenced code - blocks, autolinks, strikethroughs, non-strict emphasis, etc. - -* **Safety**. Blackfriday 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/russross/blackfriday#sanitize-untrusted-content). - -* **Fast processing**. 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**. Blackfriday only depends on standard - library packages in Go. The source code is pretty - self-contained, so it is easy to add to any project, including - Google App Engine projects. - -* **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. Blackfriday lets 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 - ``` - -* **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. - - To preserve classes of fenced code blocks while using the bluemonday - HTML sanitizer, use the following policy: - - ``` go - p := bluemonday.UGCPolicy() - p.AllowAttrs("class").Matching(regexp.MustCompile("^language-[a-zA-Z0-9]+$")).OnElements("code") - html := p.SanitizeBytes(unsafe) - ``` - -* **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**. Blackfriday 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 (it is off by - default in the `MarkdownBasic` and `MarkdownCommon` convenience - functions), newlines in the input translate into line breaks in - the output. - -* **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 `45`, which renders as - 45. - - -Other renderers ---------------- - -Blackfriday is structured to allow alternative rendering engines. Here -are a few of note: - -* [github_flavored_markdown](https://godoc.org/github.com/shurcooL/github_flavored_markdown): - provides a GitHub Flavored Markdown renderer with fenced code block - highlighting, clickable heading anchor links. - - It's not customizable, and its goal is to produce HTML output - equivalent to the [GitHub Markdown API endpoint](https://developer.github.com/v3/markdown/#render-a-markdown-document-in-raw-mode), - except the rendering is performed locally. - -* [markdownfmt](https://github.com/shurcooL/markdownfmt): like gofmt, - but for markdown. - -* [LaTeX output](https://bitbucket.org/ambrevar/blackfriday-latex): - renders output as LaTeX. - -* [bfchroma](https://github.com/Depado/bfchroma/): provides convenience - integration with the [Chroma](https://github.com/alecthomas/chroma) code - highlighting library. bfchroma is only compatible with v2 of Blackfriday and - provides a drop-in renderer ready to use with Blackfriday, as well as - options and means for further customization. - - -TODO ----- - -* 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. - - -License -------- - -[Blackfriday is distributed under the Simplified BSD License](LICENSE.txt) - - - [1]: https://daringfireball.net/projects/markdown/ "Markdown" - [2]: https://golang.org/ "Go Language" - [3]: https://github.com/vmg/sundown "Sundown" - [4]: https://godoc.org/gopkg.in/russross/blackfriday.v2#Parse "Parse func" - [5]: https://github.com/microcosm-cc/bluemonday "Bluemonday" - [6]: https://labix.org/gopkg.in "gopkg.in" - [7]: https://github.com/golang/dep/ "dep" - [8]: https://github.com/Masterminds/glide "Glide" - - [BuildSVG]: https://travis-ci.org/russross/blackfriday.svg?branch=master - [BuildURL]: https://travis-ci.org/russross/blackfriday - [GodocV2SVG]: https://godoc.org/gopkg.in/russross/blackfriday.v2?status.svg - [GodocV2URL]: https://godoc.org/gopkg.in/russross/blackfriday.v2 diff --git a/tools/vendor/github.com/russross/blackfriday/block.go b/tools/vendor/github.com/russross/blackfriday/block.go deleted file mode 100644 index 45c21a6c..00000000 --- a/tools/vendor/github.com/russross/blackfriday/block.go +++ /dev/null @@ -1,1474 +0,0 @@ -// -// Blackfriday Markdown Processor -// Available at http://github.com/russross/blackfriday -// -// Copyright © 2011 Russ Ross . -// Distributed under the Simplified BSD License. -// See README.md for details. -// - -// -// Functions to parse block-level elements. -// - -package blackfriday - -import ( - "bytes" - "strings" - "unicode" -) - -// Parse block-level data. -// Note: this function and many that it calls assume that -// the input buffer ends with a newline. -func (p *parser) block(out *bytes.Buffer, data []byte) { - if len(data) == 0 || data[len(data)-1] != '\n' { - panic("block input is missing terminating newline") - } - - // this is called recursively: enforce a maximum depth - if p.nesting >= p.maxNesting { - return - } - p.nesting++ - - // parse out one block-level construct at a time - for len(data) > 0 { - // prefixed header: - // - // # Header 1 - // ## Header 2 - // ... - // ###### Header 6 - if p.isPrefixHeader(data) { - data = data[p.prefixHeader(out, data):] - continue - } - - // block of preformatted HTML: - // - //
