{eac}Readme Extension

Description

{eac}Readme is an {eac}Doojigger extension which loads and translates a WordPress markdown 'readme.txt' file providing shortcodes to access header lines and section blocks.

Shortcode Usage

The first used shortcode must indicate the file to load...

[eacReadme file='/docfolder/readme.txt']        # file is relative to the WordPress document root folder
[eacReadme content='/contentfolder/readme.txt'] # content file is relative to the WordPress content folder (wp-content/)
[eacReadme plugin='/pluginfolder/readme.txt']   # plugin file is relative to the WordPress plugins folder (wp-content/plugins/)
[eacReadme theme='/themefolder/readme.txt']     # theme file is relative to the WordPress themes folder (wp-content/themes/)
[eacReadme wpsvn='/slugname/trunk/readme.txt']  # load file from WordPress SVN repository
[eacReadme github='/owner/repository/main/readme.txt']        # load file from github repository

After which, headers and sections may be pulled from that file...

[eacReadme]All Headers[/eacReadme]              # parses all header lines
[eacReadme]headerName[/eacReadme]               # gets the value of the named header line

[eacReadme]All Sections[/eacReadme]             # parses all section blocks
[eacReadme]sectionName[/eacReadme]              # parses the content of the named section block
[eacReadme]sectionName/sub-section[/eacReadme]  # parses the content of the named sub-section within section block

One shortcode can do it all...

[eacReadme plugin='/pluginfolder/readme.txt']Document[/eacReadme]    # loads the file and parses the entire document

Or load the entire file as a single code block...

[eacReadme theme='/themefolder/functions.php']Code File[/eacReadme]

Readme Format

{eac}Readme expects a well-formed readme.txt file that follows the WordPress readme file standard...

=== title ===
header: value
header: value
short Description
== section ==
= sub-section =

...but supports some extensions to that standard:

• Author & Author URI

  • Author header may be a simple name or a markdown link:
    • [Author](Author URI).
  • The Author & Author URI headers, if present, are combined as a markdown [Author](Author URI).

• Homepage

  • Looks for Homepage or Plugin URI.

• Version

  • Looks for Version or Stable tag.

• Contributors

  • profileId - wordpress profile (standard)
  • [email protected] - gravatar profile
  • profileId@wordpress - wordpress profile
  • profileId@gravatar - gravatar profile
  • profileId@github - github profile
  • [display name](mailto:[email protected]) or [display name](http://www.gravatar.com/profileId/)
  • [display name](http://profiles.wordpress.org/profileId/)
  • [your name]((http://your/profile/url)

• A "banner" section may be included between the top title line and the first header line.

    === title ===
   [![banner](//image_url)](//link_url)
    header: value
    header: value
    short Description
    == section ==
    = sub-section =

• The header block may be enclosed in an html <header> or <details> tag, opening and closing each on a single line. These tags are ignored by the eacParseReadme parser but may be beneficial if posting your readme file elseware. See {eac}Readme on Github.

Note: these extensions are not supported by the WordPress Plugin Repository.

{eac}Readme supports standard markdown (readme.md) formatting for section identification.

• === title === and ## title are equivalent
• == section == and ### section are equivalent
• = sub-section = and #### sub-section are equivalent

Output HTML

When retrieving the header block with ...

[eacReadme]All Headers[/eacReadme] or \eacParseReadme::getAllHeaders()

Or when retrieving all sections with ...

[eacReadme]All Sections[/eacReadme] or \eacParseReadme::getAllSections()

Or when retrieving the entire document with ...

[eacReadme]Document[/eacReadme] or \eacParseReadme::getDocument()

Additional html tags and classes are added, including wrapping blocks within a <details> tags, adding readme-* class names, and adding <a> anchor links.

WordPress Actions

3rd-party actors may load and use the parser class included in {eac}Readme...

    do_action('eacReadme_load_parser');     // loads \eacParseReadme static class
    if (class_exists('\eacParseReadme'))
    {
        \eacParseReadme::loadFile($readme,$context);
        $html_document  = \eacParseReadme::getDocument();
        $title          = \eacParseReadme::getTitle();
        $version        = \eacParseReadme::getVersion();
        $donations      = \eacParseReadme::getHeader('donate_link');
        $description    = \eacParseReadme::getSection('description');
    }
