/**
* ## Extension Support
*
* While the "core" of libcmark is strictly compliant with the
* specification, an API is provided for extension writers to
* hook into the parsing process.
*
* It should be noted that the cmark_node API already offers
* room for customization, with methods offered to traverse and
* modify the AST, and even define custom blocks.
* When the desired customization is achievable in an error-proof
* way using that API, it should be the preferred method.
*
* The following API requires a more in-depth understanding
* of libcmark's parsing strategy, which is exposed
* [here](http://spec.commonmark.org/0.24/#appendix-a-parsing-strategy).
*
* It should be used when "a posteriori" modification of the AST
* proves to be too difficult / impossible to implement correctly.
*
* It can also serve as an intermediary step before extending
* the specification, as an extension implemented using this API
* will be trivially integrated in the core if it proves to be
* desirable.
*/

/** A syntax extension that can be attached to a cmark_parser
* with cmark_parser_attach_syntax_extension().
*
* Extension writers should assign functions matching
* the signature of the following 'virtual methods' to
* implement new functionality.
*
* Their calling order and expected behaviour match the procedure outlined
* at <http://spec.commonmark.org/0.24/#phase-1-block-structure>:
*
* During step 1, cmark will call the function provided through
* 'cmark_syntax_extension_set_match_block_func' when it
* iterates over an open block created by this extension,
* to determine whether it could contain the new line.
* If no function was provided, cmark will close the block.
*
* During step 2, if and only if the new line doesn't match any
* of the standard syntax rules, cmark will call the function
* provided through 'cmark_syntax_extension_set_open_block_func'
* to let the extension determine whether that new line matches
* one of its syntax rules.
* It is the responsibility of the parser to create and add the
* new block with cmark_parser_make_block and cmark_parser_add_child.
* If no function was provided is NULL, the extension will have
* no effect at all on the final block structure of the AST.
*
* #### Inline parsing phase hooks
*
* For each character provided by the extension through
* 'cmark_syntax_extension_set_special_inline_chars',
* the function provided by the extension through
* 'cmark_syntax_extension_set_match_inline_func'
* will get called, it is the responsibility of the extension
* to scan the characters located at the current inline parsing offset
* with the cmark_inline_parser API.
*
* Depending on the type of the extension, it can either:
*
* * Scan forward, determine that the syntax matches and return
* a newly-created inline node with the appropriate type.
* This is the technique that would be used if inline code
* (with backticks) was implemented as an extension.
* * Scan only the character(s) that its syntax rules require
* for opening and closing nodes, push a delimiter on the
* delimiter stack, and return a simple text node with its
* contents set to the character(s) consumed.
* This is the technique that would be used if emphasis
* inlines were implemented as an extension.
*
* When an extension has pushed delimiters on the stack,
* the function provided through
* 'cmark_syntax_extension_set_inline_from_delim_func'
* will get called in a latter phase,
* when the inline parser has matched opener and closer delimiters
* created by the extension together.
*
* It is then the responsibility of the extension to modify
* and populate the opener inline text node, and to remove
* the necessary delimiters from the delimiter stack.
*
* Finally, the extension should return NULL if its scan didn't
* match its syntax rules.
*
* The extension can store whatever private data it might need
* with 'cmark_syntax_extension_set_private',
* and optionally define a free function for this data.

/**
* ### Plugin API.
*
* Extensions should be distributed as dynamic libraries,
* with a single exported function named after the distributed
* filename.
*
* When discovering extensions (see cmark_init), cmark will
* try to load a symbol named "init_{{filename}}" in all the
* dynamic libraries it encounters.
*
* For example, given a dynamic library named myextension.so
* (or myextension.dll), cmark will try to load the symbol
* named "init_myextension". This means that the filename
* must lend itself to forming a valid C identifier, with
* the notable exception of dashes, which will be translated
* to underscores, which means cmark will look for a function
* named "init_my_extension" if it encounters a dynamic library
* named "my-extension.so".
*
* See the 'cmark_plugin_init_func' typedef for the exact prototype
* this function should follow.
*
* For now the extensibility of cmark is not complete, as
* it only offers API to hook into the block parsing phase
* (<http://spec.commonmark.org/0.24/#phase-1-block-structure>).
*
* See 'cmark_plugin_register_syntax_extension' for more information.

* ## Iterator
*
* An iterator will walk through a tree of nodes, starting from a root
* node, returning one node at a time, together with information about
* whether the node is being entered or exited. The iterator will
* first descend to a child node, if there is one. When there is no
* child, the iterator will go to the next sibling. When there is no
* next sibling, the iterator will return to the parent (but with
* a 'cmark_event_type' of `CMARK_EVENT_EXIT`). The iterator will
* return `CMARK_EVENT_DONE` when it reaches the root node again.
* One natural application is an HTML renderer, where an `ENTER` event
* outputs an open tag and an `EXIT` event outputs a close tag.
* An iterator might also be used to transform an AST in some systematic
* way, for example, turning all level-3 headings into regular paragraphs.

\- convert CommonMark formatted text with GitHub Flavored Markdown extensions to HTML
.SH "SYNOPSIS"
.HP 6n
\fBcmark-gfm\fR
[options]
file*
.SH "DESCRIPTION"
\fBcmark-gfm\fR
converts Markdown formatted plain text to either HTML, groff man,
CommonMark XML, LaTeX, or CommonMark, using the conventions
described in the CommonMark spec. It reads input from \fIstdin\fR
or the specified files (concatenating their contents) and writes
output to \fIstdout\fR.
.SH "OPTIONS"
.TP 12n
.B \-\-to, \-t \f[I]FORMAT\f[]
Specify output format (\f[C]html\f[], \f[C]man\f[], \f[C]xml\f[],
\f[C]latex\f[], \f[C]commonmark\f[]).
.TP 12n
.B \-\-width \f[I]WIDTH\f[]
Specify a column width to which to wrap the output. For no wrapping, use
the value 0 (the default). This option currently only affects the
commonmark, latex, and man renderers.
.TP 12n
.B \-\-hardbreaks
Render soft breaks (newlines inside paragraphs in the CommonMark source)
as hard line breaks in the target format. If this option is specified,
hard wrapping is disabled for CommonMark output, regardless of the value
given with \-\-width.
.TP 12n
.B \-\-nobreaks
Render soft breaks as spaces. If this option is specified,
hard wrapping is disabled for all output formats, regardless of the value
given with \-\-width.
.TP 12n
.B \-\-sourcepos
Include source position attribute.
.TP 12n
.B \-\-normalize
Consolidate adjacent text nodes.
.TP 12n
.B \-\-extension, \-e \f[I]EXTENSION_NAME\f[]
Specify an extension name to use.
.TP 12n
.B \-\-list\-extensions
List available extensions and quit.
.TP 12n
.B \-\-validate-utf8
Validate UTF-8, replacing illegal sequences with U+FFFD.
.TP 12n
.B \-\-smart
Use smart punctuation. Straight double and single quotes will
be rendered as curly quotes, depending on their position.
\f[C]\-\-\f[] will be rendered as an en-dash.
\f[C]\-\-\-\f[] will be rendered as an em-dash.
\f[C]...\f[] will be rendered as ellipses.
.TP 12n
.B \-\-unsafe
Render raw HTML and potentially dangerous URLs.
(Raw HTML is not replaced by a placeholder comment; potentially
dangerous URLs are not replaced by empty strings.) Dangerous
URLs are those that begin with `javascript:`, `vbscript:`,
`file:`, or `data:` (except for `image/png`, `image/gif`,
`image/jpeg`, or `image/webp` mime types).
.TP 12n
.B \-\-help
Print usage information.
.TP 12n
.B \-\-version
Print version.
