vendor test dependencies instead of installing via network
We can vendor the test dependencies such as go-md2man, git-validation
and goimports. This allows us to always install the same version as
specified in go.mod. Also we do not rely on a network connection for
this.
The advantage with this method is that dependabot will also update the
dependencies for us and we do not have to hardcode versions in the
Makefile.

You must inform recipients that the Source Code Form + of the Covered Software is governed by the terms of this License, and how + they can obtain a copy of this License. You may not attempt to alter or + restrict the recipients’ rights in the Source Code Form. + +3.2. Distribution of Executable Form + + If You distribute Covered Software in Executable Form then: + + a. such Covered Software must also be made available in Source Code Form, + as described in Section 3.1, and You must inform recipients of the + Executable Form how they can obtain a copy of such Source Code Form by + reasonable means in a timely manner, at a charge no more than the cost + of distribution to the recipient; and + + b. You may distribute such Executable Form under the terms of this License, + or sublicense it under different terms, provided that the license for + the Executable Form does not attempt to limit or alter the recipients’ + rights in the Source Code Form under this License. + +3.3. Distribution of a Larger Work + + You may create and distribute a Larger Work under terms of Your choice, + provided that You also comply with the requirements of this License for the + Covered Software. If the Larger Work is a combination of Covered Software + with a work governed by one or more Secondary Licenses, and the Covered + Software is not Incompatible With Secondary Licenses, this License permits + You to additionally distribute such Covered Software under the terms of + such Secondary License(s), so that the recipient of the Larger Work may, at + their option, further distribute the Covered Software under the terms of + either this License or such Secondary License(s). + +3.4.

Application of Additional Terms + + You may choose to offer, and to charge a fee for, warranty, support, + indemnity or liability obligations to one or more recipients of Covered + Software. However, You may do so only on Your own behalf, and not on behalf + of any Contributor. You must make it absolutely clear that any such + warranty, support, indemnity, or liability obligation is offered by You + alone, and You hereby agree to indemnify every Contributor for any + liability incurred by such Contributor as a result of warranty, support, + indemnity or liability terms You offer. You may include additional + disclaimers of warranty and limitations of liability specific to any + jurisdiction. + +4. Inability to Comply Due to Statute or Regulation + + If it is impossible for You to comply with any of the terms of this License + with respect to some or all of the Covered Software due to statute, judicial + order, or regulation then You must: (a) comply with the terms of this License + to the maximum extent possible; and (b) describe the limitations and the code + they affect.

This limitation of liability + shall not apply to liability for death or personal injury resulting from such + party’s negligence to the extent applicable law prohibits such limitation. + Some jurisdictions do not allow the exclusion or limitation of incidental or + consequential damages, so this exclusion and limitation may not apply to You. + +8. Litigation + + Any litigation relating to this License may be brought only in the courts of + a jurisdiction where the defendant maintains its principal place of business + and such litigation shall be governed by laws of that jurisdiction, without + reference to its conflict-of-law provisions. Nothing in this Section shall + prevent a party’s ability to bring cross-claims or counter-claims. + +9. Miscellaneous + + This License represents the complete agreement concerning the subject matter + hereof. If any provision of this License is held to be unenforceable, such + provision shall be reformed only to the extent necessary to make it + enforceable. Any law or regulation which provides that the language of a + contract shall be construed against the drafter shall not be used to construe + this License against a Contributor. + + +10.

Modified Versions + + If you create software not governed by this License, and you want to + create a new license for such software, you may create and use a modified + version of this License if you rename the license and remove any + references to the name of the license steward (except to note that such + modified license differs from this License). + +10.4.

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 modern Go releases in module mode. +With Go installed: + + go get github.com/russross/blackfriday/v2 + +will resolve and add the package to the current development module, +then build and install it. Alternatively, you can achieve the same +if you import it in a package: + + import "github.com/russross/blackfriday/v2" + +and `go get` without parameters. + +Legacy GOPATH mode is unsupported. + + +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://pkg.go.dev/github.com/russross/blackfriday/v2. + +It is `go get`-able in module mode at `github.com/russross/blackfriday/v2`. + +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://pkg.go.dev/github.com/russross/blackfriday. + + +Usage +----- + +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" + "github.com/russross/blackfriday/v2" +) + +// ... +unsafe := blackfriday.Run(input) +html := bluemonday.UGCPolicy().SanitizeBytes(unsafe) +``` + +### Custom options + +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: + +* <https://github.com/russross/blackfriday-tool> + +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 `AutoHeadingIDs` extension 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://pkg.go.dev/github.com/russross/blackfriday/v2#hdr-Sanitized_Anchor_Names. + +[`SanitizedAnchorName`](https://pkg.go.dev/github.com/russross/blackfriday/v2#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://pkg.go.dev/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 newlines in the input + translate into line breaks 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>. + + +Other renderers +--------------- + +Blackfriday is structured to allow alternative rendering engines. Here +are a few of note: + +* [github_flavored_markdown](https://pkg.go.dev/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://gitlab.com/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. + +* [Blackfriday-Confluence](https://github.com/kentaro-m/blackfriday-confluence): provides a [Confluence Wiki Markup](https://confluence.atlassian.com/doc/confluence-wiki-markup-251003035.html) renderer. + +* [Blackfriday-Slack](https://github.com/karriereat/blackfriday-slack): converts markdown to slack message style + + +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://pkg.go.dev/github.com/russross/blackfriday/v2#Parse "Parse func" + [5]: https://github.com/microcosm-cc/bluemonday "Bluemonday" + + [BuildV2SVG]: https://travis-ci.org/russross/blackfriday.svg?branch=v2 + [BuildV2URL]: https://travis-ci.org/russross/blackfriday + [PkgGoDevV2SVG]: https://pkg.go.dev/badge/github.com/russross/blackfriday/v2 + [PkgGoDevV2URL]: https://pkg.go.dev/github.com/russross/blackfriday/v2 diff --git a/vendor/github.com/russross/blackfriday/v2/block.go b/vendor/github.com/russross/blackfriday/v2/block.go new file mode 100644 index 000000000..dcd61e6e3 --- /dev/null +++ b/vendor/github.com/russross/blackfriday/v2/block.go @@ -0,0 +1,1612 @@ +// +// Blackfriday Markdown Processor +// Available at http://github.com/russross/blackfriday +// +// Copyright © 2011 Russ Ross <russ@russross.com>. +// Distributed under the Simplified BSD License. +// See README.md for details. +// + +// +// Functions to parse block-level elements. +// + +package blackfriday + +import ( + "bytes" + "html" + "regexp" + "strings" + "unicode" +) + +const ( + charEntity = "&(?:#x[a-f0-9]{1,8}|#[0-9]{1,8}|[a-z][a-z0-9]{1,31});" + escapable = "[!\"#$%&'()*+,./:;<=>?@[\\\\\\]^_`{|}~-]" +) + +var ( + reBackslashOrAmp = regexp.MustCompile("[\\&]") + reEntityOrEscapedChar = regexp.MustCompile("(?i)\\\\" + escapable + "|" + charEntity) +) + +// Parse block-level data. +// Note: this function and many that it calls assume that +// the input buffer ends with a newline. +func (p *Markdown) block(data []byte) { + // 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 heading: + // + // # Heading 1 + // ## Heading 2 + // ... + // ###### Heading 6 + if p.isPrefixHeading(data) { + data = data[p.prefixHeading(data):] + continue + } + + // block of preformatted HTML: + // + // <div> + // ... + // </div> + if data[0] == '<' { + if i := p.html(data, true); i > 0 { + data = data[i:] + continue + } + } + + // title block + // + // % stuff + // % more stuff + // % even more stuff + if p.extensions&Titleblock != 0 { + if data[0] == '%' { + if i := p.titleBlock(data, true); i > 0 { + data = data[i:] + continue + } + } + } + + // blank lines. note: returns the # of bytes to skip + if i := p.isEmpty(data); i > 0 { + data = data[i:] + continue + } + + // indented code block: + // + // func max(a, b int) int { + // if a > b { + // return a + // } + // return b + // } + if p.codePrefix(data) > 0 { + data = data[p.code(data):] + continue + } + + // fenced code block: + // + // ``` go + // func fact(n int) int { + // if n <= 1 { + // return n + // } + // return n * fact(n-1) + // } + // ``` + if p.extensions&FencedCode != 0 { + if i := p.fencedCodeBlock(data, true); i > 0 { + data = data[i:] + continue + } + } + + // horizontal rule: + // + // ------ + // or + // ****** + // or + // ______ + if p.isHRule(data) { + p.addBlock(HorizontalRule, nil) + var i int + for i = 0; i < len(data) && data[i] != '\n'; i++ { + } + data = data[i:] + continue + } + + // block quote: + // + // > A big quote I found somewhere + // > on the web + if p.quotePrefix(data) > 0 { + data = data[p.quote(data):] + continue + } + + // table: + // + // Name | Age | Phone + // ------|-----|--------- + // Bob | 31 | 555-1234 + // Alice | 27 | 555-4321 + if p.extensions&Tables != 0 { + if i := p.table(data); i > 0 { + data = data[i:] + continue + } + } + + // an itemized/unordered list: + // + // * Item 1 + // * Item 2 + // + // also works with + or - + if p.uliPrefix(data) > 0 { + data = data[p.list(data, 0):] + continue + } + + // a numbered/ordered list: + // + // 1.

All runes that are letters (category L) +// or numbers (category N) are considered valid characters. They are mapped to +// lower case, and included in the output.
