This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



With Pastacode, you can easily add code into your posts with the awesome PrismJs coloration library.
You can insert source code into the post editor, wrinting it directly in the editor (using a gutenberg bloc or classic editor), from a file, or from webservices like GitHub, Gitlab, Gist, Pastebin, BitBucket or BitBucket snippets. Webservices responses are cached in order to avoid too many HTTP requests.
It also work in comments and bbPress topics and replies.

Don’t worry about posts updates while upgrading codes!

Pastacode allows to enhance your snippets using PrismJs plugins (highlightning lines, link functions…).

add_filter( 'option_pastacode_cache_duration', 'my_pastacode_cache_duration' );
function my_pastacode_cache_duration( $duration ) {
    $duration = DAY_IN_SECOND*3; // 3 days
    return $duration;

How to change the color scheme ?

Paste these lines into your functions.php theme file:

Get inspired of the default scheme to build your schemes

How to filter supported languages ?

Paste these lines into your functions.php theme file:

//If you just want php, html, css and javascript support
add_filter( 'pastacode_langs', '_pastacode_langs' );
function _pastacode_langs( $langs ) {
    $langs  = array(
        'php'          => 'PHP',
        'markup'       => 'HTML',
        'css'          => 'CSS',
        'javascript'   => 'JavaScript', );
    return $langs;

Ajax compatibility

To enable Pastacode on ajax based websites, it need two steps:

  1. Turn on Legacy support in the settings panel
  2. Paste this line into your functions.php theme file: add_filter( 'pastacode_ajax', '__return_true' );
  3. After each change on your DOM, you will have to run this javascript function: Prism.highlightAll();

How to add a new provider ?

Paste these lines into your functions.php theme file:

//Take WordPress SVN, for example
//register a provider
add_filter( 'pastacode_services', '_pastacode_services' );
function _pastacode_services( $services ) {
    $services['wordpress'] = '';
    return $services;

//Define pastabox lightbox inputs
add_action( 'pastacode_fields', '_pastacode_fields' );
function _pastacode_fields( $fields ) { 
    $fields['wordpress'] = array(  // 'wordpress' or 'whatever'
        'classes'     => array( 'wordpress' ), // same value as the key
        'label'       => sprintf( __('File path relative to %s', 'pastacode'), '' ), 
        'placeholder' =>'trunk/wp-config-sample.php', //if placeholder isn't defined, it will be a textarea
        'name'        => 'path_id' //these value return shortcode attribute (path_id, repos, name, user, version)
    $fields['pastacode-lines']['classes'][] = 'wordpress'; // Add ability to select lines
    $fields['pastacode-highlight']['classes'][] = 'wordpress'; // Add ability to highlight somes

    return $fields;

//Build the function to retrieve the code
// "pastacode_wordpress" hook name (1st param) = "pastacode_" + "wordpress" or "whatever"
add_action( 'pastacode_wordpress', '_pastacode_wordpress', 10, 2 );
function _pastacode_wordpress( $source, $atts ) {
    extract( $atts );
    if( $path_id ) {
        $req  = wp_sprintf( '', str_replace( '', '', $path_id ) );
        $code = wp_remote_get( $req );
        if( ! is_wp_error( $code ) && 200 == wp_remote_retrieve_response_code( $code ) ) {
            $data = wp_remote_retrieve_body( $code );
            $source[ 'url' ]  = $req; //url to view source
            $source[ 'name' ] = basename( $req ); //filename
            $source[ 'code' ] = esc_html( $data ); //the code !!   
            //$source[ 'raw' ] contain raw source code. But there are no raw source code delivered by WordPress SVN             
    return $source;

Do not add you root website!! A contributor can add the shortcode to point your “wp-config.php” to read it!!
