NAME

Regexp::Common::Markdown - Markdown Common Regular Expressions

SYNOPSIS

    use Regexp::Common qw( Markdown );

    while( <> )
    {
        my $pos = pos( $_ );
        /\G$RE{Markdown}{Header}/gmc   and  print "Found a header at pos $pos\n";
        /\G$RE{Markdown}{Bold}/gmc     and  print "Found bold text at pos $pos\n";
    }

VERSION

    v0.1.4

DESCRIPTION

This module provides Markdown regular expressions as set out by its original author John Gruber

There are different types of patterns: vanilla and extended. To get the extended regular expressions, use the -extended switch.

You can use each regular expression by using their respective names: Bold, Blockquote, CodeBlock, CodeLine, CodeSpan, Em, HtmlOpen, HtmlClose, HtmlEmpty, Header, HeaderLine, Image, ImageRef, Line, Link, LinkAuto, LinkDefinition, LinkRef, List

Almost all of the regular expressions use named capture. See "%+" in perlvar for more information on named capture.

For example:

    if( $text =~ /$RE{Markdown}{LinkAuto}/ )
    {
        print( "Found https url \"$+{link_https}\"\n" ) if( $+{link_https} );
        print( "Found file url \"$+{link_file}\"\n" ) if( $+{link_file} );
        print( "Found ftp url \"$+{link_ftp}\"\n" ) if( $+{link_ftp} );
        print( "Found e-mail address \"$+{link_mailto}\"\n" ) if( $+{link_mailto} );
        print( "Found Found phone number \"$+{link_tel}\"\n" ) if( $+{link_tel} );
        my $url = URI->new( $+{link_https} );
    }

As a general rule, Markdown rule requires that the text being parsed be de-tabbed, i.e. with its tabs converted into 4 spaces. Those regular expressions reflect this principle.

STANDARD MARKDOWN

`$RE{Markdown}`

This returns a pattern that recognises any of the supported vanilla Markdown formatting. If you pass the -extended parameter, some will be added and some of those regular expressions will be replaced by their extended ones, such as ExtAbbr, ExtCodeBlock, ExtLink, ExtAttributes

Blockquote

    $RE{Markdown}{Blockquote}

For example:

    > foo
    >
    > > bar
    >
    > foo

You can see example of this regular expression along with test units here: https://regex101.com/r/TdKq0K/1/tests

The capture names are:

bquote_all: The entire capture of the blockquote.
bquote_other: The inner content of the blockquote.

You can see also Markdown::Parser::Blockquote

Bold

    $RE{Markdown}{Bold}

For example:

    **This is a text in bold.**

    __And so is this.__

You can see example of this regular expression along with test units here: https://regex101.com/r/Jp2Kos/2/tests

The capture names are:

bold_all: The entire capture of the text in bold including the enclosing marker, which can be either ** or __
bold_text: The text within the markers.
bold_type: The marker type used to highlight the text. This can be either ** or __

You can see also Markdown::Parser::Bold

Code Block

    $RE{Markdown}{CodeBlock}

For example:

    ```
    Some text

        Indented code block sample code
    ```

You can see example of this regular expression along with test units here: https://regex101.com/r/M6W99K/1/tests

The capture names are:

code_all: The entire capture of the code block, including the enclosing markers, such as ```
code_content: The content of the code enclosed within the 2 markers.
code_start: The enclosing marker used to mark the code. Typically ```.
code_trailing_new_line: The possible trailing new lines. This is used to detect if any were captured in order to put them back in the parsed text for the next markdown, since the last new lines of a markdown are alos the first new lines of the next ones and new lines are used to delimit markdowns.

You can see also Markdown::Parser::Code

Code Line

    $RE{Markdown}{CodeLine}

For example:

        the lines in this block  
        all contain trailing spaces

header_all

The entire capture of the code lines.

header_content

The capture names are:

html_all

The entire capture of the html block.

html_comment

If this html block is a comment, this will contain the data within the comment.

html_content

The inner content between the opning and closing tag. This could be more html block or some text.

This capture will not be available obviously for html tags that are "empty" by nature, such as <hr />

Here, the attributes will be:

    title="Start" class="center large" id="extra_stuff"

tag_close

The closing tag, including enclosing brackets.

tag_name

This contains the name of the first html tag encountered, i.e. the one that starts the html block. For example:

You can see also Markdown::Parser::HTML

Image

    $RE{Markdown}{Image}

or, with reference:

    ![alt text][foo]

You can see example of this regular expression along with test units here: https://regex101.com/r/z0yH2F/4/tests

The capture names are:

img_all

The entire capture of the markdown, such as:

    ![Alt text](/path/to/img.jpg)

img_alt

The alternative tet to be displayed for this image. This is mandatory as per markdown, so it is guaranteed to be available.

img_id

If the image, is an image reference, this will contain the reference id. When an image id is provided, there is no url and no title, because the image reference provides those information.

img_title

This is the title of the image, which may not exist, since it is optional in markdown. The title is surrounded by single or double quote that are captured in img_title_container

img_url

This is the url of the image.

Line

    $RE{Markdown}{Line}

    Sa robe de pourpre au soleil,  
    A point perdu cette vesprée,  
    Les plis de sa robe pourprée,  
    Et son teint au vôtre pareil.

To ensure arbitrary line breaks, each line ends with 2 spaces and 1 line break. This should become:

    Mignonne, allons voir si la rose<br />
    Qui ce matin avait déclose<br />
    Sa robe de pourpre au soleil,<br />
    A point perdu cette vesprée,<br />
    Les plis de sa robe pourprée,<br />

You can see example of this regular expression along with test units here: https://regex101.com/r/6VG46H/1/

There is only one capture name: br_all. This is basically used like this:

    if( $text =~ /\G$RE{Markdown}{LineBreak}/ )
    {
        print( "Found a line break\n" );
    }

    $text =~ s/$RE{Markdown}{LineBreak}/<br \/>\n/gs;

List First Level

    $RE{Markdown}{ListFirstLevel}

This regular expression is used for top level list, as opposed to the nth level pattern that is used for sub list. Both will match lists within list, but the processing under markdown is different whether the list is a top level one or an sub one.

You can see also Markdown::Parser::List

List Nth Level

    $RE{Markdown}{ListNthLevel}

Regular expression to process list within list.

Paragraph

    $RE{Markdown}{Paragraph}

For example:

    jumps over the lazy dog

    Lorem Ipsum

    > Why am I matching?
    1. Nonononono!
    * Aaaagh!
    # Stahhhp!

This regular expression would capture the whole block up until "Lorem Ipsum", but will be careful not to catch other markdown element after that. Thus, anything after "Lorem Ipsum" would not be caught because this is a blockquote.

You can see example of this regular expression along with test units here: https://regex101.com/r/0B3gR4/3

The capture names are:

para_all: The entire capture of the paragraph.
para_content: Content of the paragraph

    ### Header  {.cl.class#id7 }

Code Block

    $RE{Markdown}{ExtCodeBlock}

This is the same as conventional blocks with backticks, except the extended version uses tilde characters.

For example:

    ~~~
    <div>
    ~~~

You can see example of this regular expression along with test units here: https://regex101.com/r/Y9lPAz/2/tests

The capture names are:

code_all

The entire capture of the code.

code_attr

The class and/or id attributes for this code. This is something like:

    `````` .html {#codeid}
    </div>
    ``````

Here, code_class would contain #codeid

code_class

The class of code. For example:

    ``````html {#codeid}
    </div>
    ``````

Here the code class would be html

Footnotes

    $RE{Markdown}{ExtFootnote}

This looks like this:

    [^1]: Content for fifth footnote.
    [^2]: Content for sixth footnote spaning on 
        three lines, with some span-level markup like
        _emphasis_, a [link][].

A reference to those footnotes could be:

    Some paragraph with a footnote[^1], and another[^2].

The footnote_id reference can be anything as long as it is unique.

You can see also Markdown::Parser::Footnote

Inline Footnotes

For consistency with links, footnotes can be added inline, like this:

    I met Jack [^jack](Co-founder of Angels, Inc) at the meet-up.

Inline notes will work even without the identifier. For example:

    I met Jack [^](Co-founder of Angels, Inc) at the meet-up.

However, in compliance with pandoc footnotes style, inline footnotes can also be added like this:

    Here is an inline note.^[Inlines notes are easier to write, since
    you don't have to pick an identifier and move down to type the
    note.]

You can see example of this regular expression along with test units here: https://regex101.com/r/WuB1FR/2/

The capture names are:

footnote_all: The entire capture of the footnote.
footnote_id: The footnote id which must be unique and will be referenced in text.
footnote_text: The footnote text

You can see also Markdown::Parser::Footnote

Footnote Reference

    $RE{Markdown}{ExtFootnoteReference}

This regular expression matches 3 types of footnote references:

1 Conventional

An id is specified referring to a footnote that provide details.

    Here's a simple footnote,[^1]

    [^1]: This is the first footnote.

2 Inline

    I met Jack [^jack](Co-founder of Angels, Inc) at the meet-up.

Inline footnotes without any id, i.e. auto-generated id. For example:

    I met Jack [^](Co-founder of Angels, Inc) at the meet-up.

3 Inline auto-generated, pandoc style

    Here is an inline note.^[Inlines notes are easier to write, since
    you don't have to pick an identifier and move down to type the
    note.]

See pandoc manual for more information

You can see example of this regular expression along with test units here: https://regex101.com/r/3eO7rJ/1/

The capture names are:

footnote_all

The entire capture of the footnote reference.

footnote_id

The footnote id which must be unique and must match a footnote declared anywhere in the document and not necessarily before. For example:

    Here's a simple footnote,[^1]

    [^1]: This is the first footnote.

1 here is the id fo the footnote.

If it is not provided, then an id will be auto-generated, but a footnote text is then required.

footnote_text

The footnote text is optional if an id is provided. If an id is not provided, the fotnote text is guaranteed to have some value.

You can see also Markdown::Parser::FootnoteReference
