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]
Shortcode Examples
Get header values...
[eacReadme]Contributors[/eacReadme]
[eacReadme]Donate link[/eacReadme]
[eacReadme]Requires at least[/eacReadme]
[eacReadme]Stable tag[/eacReadme]
Get unnamed segments...
[eacReadme]Title[/eacReadme] # gets the '=== plugin name ===' line (before headers)
[eacReadme]Short Description[/eacReadme] # gets the short description (between headers and first section block)
Get section blocks...
[eacReadme]Description[/eacReadme]
[eacReadme]Installation[/eacReadme]
[eacReadme]Screenshots[/eacReadme]
[eacReadme]Changelog[/eacReadme]
Get multiple blocks and/or sub-sections...
[eacReadme plugin='/eacReadme/readme.txt']Short Description,Description[/eacReadme]
[eacReadme plugin='/eacReadme/readme.txt']Short Description,Description/Shortcode Examples[/eacReadme]
Get a file as a code block...
[eacReadme theme='/my-child-theme/functions.js' lang='js']Code File[/eacReadme]
[eacReadme theme='/my-child-theme/style.css' lang='css']Code File[/eacReadme]
Other Options

define('EAC_README_CACHE_LIFETIME',$seconds); # default: 1-day (DAY_IN_SECONDS).
Override the default cache time-to-live
[eacReadme ttl=$seconds ...] # minimum: 1-minute (MINUTE_IN_SECONDS).
Set the default GitHub access token (for private repositories):
define('GITHUB_ACCESS_TOKEN',$token);
Set/override the GitHub access token
[eacReadme token=$token ...]
Override option to parse markdown when retrieving a segment
[eacReadme parse='true|false' ...]
Set class='language-*' on code blocks
[eacReadme lang='php|js|css|html' ...]
Translating Header/Section Names
Translate header/section names when retrieving All Headers, All Sections, or Document
[eacReadme translate='name=newname,...']
[eacReadme translate='Requires at least=Requires WordPress Version,Screenshots=Screen Shots']
Erase default translation table
[eacReadme translate='no|none|false']
Default translation table
[
'Headers' => 'Document Header',
'Plugin URI' => 'Homepage',
'Stable tag' => 'Current Version',
'Requires at least' => 'Requires WordPress Version',
'Tested up to' => 'Compatible up to',
'Requires PHP' => 'Requires PHP Version',
'WC requires at least' => 'Requires WooCommerce',
'Requires EAC' => 'Requires {eac}Doojigger',
'Changelog' => 'Change Log',
'Screenshots' => 'Screen Shots',
];
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
orPlugin URI
.
- Looks for
-
Version
- Looks for
Version
orStable tag
.
- Looks for
-
Contributors
profileId
- wordpress profile (standard)[email protected]
- gravatar profileprofileId@wordpress
- wordpress profileprofileId@gravatar
- gravatar profileprofileId@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');
}

*
* Here, we add click() actions to the above anchor links to use as tabs,
