-Blackfriday
-[![Build Status][BuildV2SVG]][BuildV2URL]
-[![PkgGoDev][PkgGoDevV2SVG]][PkgGoDevV2URL]
-===========
-
-Blackfriday is a [Markdown][1] processor implemented in [Go][2]. 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 `&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>.
-
-
-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.

-// Package blackfriday is a markdown processor.
-//
-// It translates plain text with simple formatting rules into an AST, which can
-// then be further processed to HTML (provided by Blackfriday itself) or other
-// formats (provided by the community).
-//
-// The simplest way to invoke Blackfriday is to call the Run function. It will
-// take a text input and produce a text output in HTML (or other format).
-//
-// A slightly more sophisticated way to use Blackfriday is to create a Markdown
-// processor and to call Parse, which returns a syntax tree for the input
-// document. You can leverage Blackfriday's parsing for content extraction from
-// markdown documents. You can assign a custom renderer and set various options
-// to the Markdown processor.
-//
-// If you're interested in calling Blackfriday from command line, see
-// https://github.com/russross/blackfriday-tool.
-//
-// 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 is specified below, so that other packages can create
-// compatible anchor names and links to those anchors.
-//
-// The algorithm iterates over the input text, interpreted as UTF-8,
-// one Unicode code point (rune) at a time. 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. All other runes are considered
-// invalid characters. Invalid characters that precede the first valid character,
-// as well as invalid character that follow the last valid character
-// are dropped completely. All other sequences of invalid characters
-// between two valid characters are replaced with a single dash character '-'.
-//
-// 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. It can be useful for clients
-// that want a small package and don't need full functionality of blackfriday.
-package blackfriday
-
-// NOTE: Keep Sanitized Anchor Name algorithm in sync with package
-//       github.com/shurcooL/sanitized_anchor_name.
-//       Otherwise, users of sanitized_anchor_name will get anchor names
-//       that are incompatible with those generated by blackfriday.

-
-cli is a simple, fast, and fun package for building command line apps in Go. The
-goal is to enable developers to write fast and distributable command line
-applications in an expressive way.
-
-## Usage Documentation
-
-Usage documentation for `v1` is available [at the docs
-site](https://cli.urfave.org/v1/getting-started/) or in-tree at
-[./docs/v1/manual.md](./docs/v1/manual.md)
-
-## Installation
-
-Make sure you have a working Go environment. Go version 1.18+ is supported.
-
-### Supported platforms
-
-cli is tested against multiple versions of Go on Linux, and against the latest released
-version of Go on OS X and Windows.  For full details, see
-[./.github/workflows/cli.yml](./.github/workflows/cli.yml).
-
-### Build tags
-
-You can use the following build tags:
-
-#### `urfave_cli_no_docs`
-
-When set, this removes `ToMarkdown` and `ToMan` methods, so your application
-won't be able to call those. This reduces the resulting binary size by about
-300-400 KB (measured using Go 1.18.1 on Linux/amd64), due to less dependencies.
-
-### Using `v1` releases
-
-```
-$ go get github.com/urfave/cli
-```
-
-```go
-...
-import (
-  "github.com/urfave/cli"
-)

+
+urfave/cli is a **declarative**, simple, fast, and fun package for building
+command line tools in Go featuring:
+
+- commands and subcommands with alias and prefix match support
+- flexible and permissive help system
+- dynamic shell completion for `bash`, `zsh`, `fish`, and `powershell`
+- no dependencies except Go standard library
+- input flags for simple types, slices of simple types, time, duration, and
+  others
+- compound short flag support (`-a` `-b` `-c` can be shortened to `-abc`)
+- documentation generation in `man` and Markdown (supported via the
+  [`urfave/cli-docs`][urfave/cli-docs] module)
+- input lookup from:
+  - environment variables
+  - plain text files
+  - structured file formats (supported via the
+    [`urfave/cli-altsrc`][urfave/cli-altsrc] module)
+
