Code Syntax Block

Opis

Code Syntax Block extends the WordPress Block Editor by adding syntax highlighting support to the core code block using the Prism syntax highlighter.

The Prism syntax highlighter runs JavaScript loaded on the front-end to parse code blocks and apply syntax markup. A CSS file specifies the color and style to apply to that markup. See Prism syntax highlighter for full details.

Instalacija

After installing and activating the plugin, use in the Block Editor by creating a standard code block and selecting a language format.

When creating a new code block, select Code block, and then in the Inspector (Block Controls on the Right) select the language for the code. The code will not change within the editor, but you’ll see a small label with the selected language.

On the front-end when the post is being viewed, the code will be color syntax highlighted.

What languages are supported?

The Code Syntax Block plugin uses the Prism autoloader plugin to support all of the languages Prism supports. See the list of supported languages here.

How to customize the color scheme?

The default color theme is A11y Dark optimized for accessibility. If you want to change the colorscheme, you can select in the editor from a few different themes shipped with the plugin. You can also use a theme from the Prism themes repo or create your own.

The color theme is a single CSS file, there are a couple ways to customize:

  1. The plugin will check the current theme for the file: assets/prism/prism.css and use that file if it exists. Add your custom file in that location, and it will be used.

  2. If you do not like that file location, you can use the filter mkaz_prism_css_path and specify a path relative to your theme to use.

  3. If you would prefer specifying a full URL, you can use the filter mkaz_prism_css_url and specify a full URL to the stylesheet to use.

An example adding a filter to change the URL, add the following to your theme’s function.php

add_filter( 'mkaz_prism_css_url', function() {
    return 'https://raw.githubusercontent.com/PrismJS/prism-themes/master/themes/prism-hopscotch.css';

});

Note: if you use the title/filename feature and customize the CSS, you will need to apply your own style targeting the prism-titlename class.

How to customize the language list?

Use the filter mkaz_code_syntax_language_list to customize the list of languages to select displayed in the editor. By default the code syntax block shows a shorter list of popular languages, but Prism supports close to 200, see list.

Use this filter to extend to support the languages you need. Additionally you can use the filter to shorten the list to just the languages you use to make it easier to select.

Here is an example shortening the list to a smaller set:

add_filter( 'mkaz_code_syntax_language_list', function() {
    return array(
        "bash" => "Bash",
        "go" => "Go",
        "html" => "HTML",
        "javascript" => "JavaScript",
        "json" => "JSON",
        "markdown" => "Markdown",
        "php" => "PHP",
        "python" => "Python",
        "jsx" => "React JSX",
        "sass" => "Sass",
        "sql" => "SQL",
        "svg" => "SVG",
        "toml" => "TOML",
        "vim" => "vim",
        "xml" => "XML",
        "yaml" => "YAML",
    );
} );

Can I set a default language so I don’t have to select each time?

Yes, use the filter mkaz_code_syntax_default_lang to set a default language when inserting a code block. You can still change if you wish to show code not using the default language.

This example would set JavaScript as the default:

add_filter( 'mkaz_code_syntax_default_lang', function() { return 'javascript'; });

Can I override the conditional loading, so assets always load?

Yes, use the filter mkaz_code_syntax_force_loading to force always loading assets, otherwise it users has_block to check.

Example:

add_filter( 'mkaz_code_syntax_force_loading', '__return_true' );

The beauty of this plugin is that it blends extremely well with the Gutenberg Code block. Simply install the plugin and select the language for the code blocks in your posts. That's it!

I've tried many other plugins but they are not fully customizable with all languages and then I want to use prism.js but this plugin does all of that, just love it the way it works out of the box without extra setup. Thanks to the Plugin Author.

It may lack options, but it looks great, and supports plenty of languages, and styles.. Its also very easy to use out of the box, so 5 stars!

I love this plugin! I'm glad I read about it on WP Tavern today. I just tried it and it works like a charm. I really like that no configuration is necessary to make it work. And also that it simply expands the Core block instead of adding unnecessary additional blocks. It's already responsive and looks great! I have tried at least 3 other popular syntax highlighter plugins, and this is by far the best. Great job!
