WP-Syntax

Опис

WP-Syntax provides clean syntax highlighting using
GeSHi — supporting a wide range of popular
languages. It supports highlighting with or without line numbers and maintains formatting while copying snippets of code
from the browser.

It avoids conflicts with other 3rd party plugins by running an early
pre-filter and a late post-filter that substitutes and pulls the code snippets
out first and then pushes them back in with highlighting at the end. The
result is source code formatted and highlighted the way you intended.

Usage, Supported Languages, Styling Guidelines, and Release Notes are available
in the Other Notes section.

Basic Usage

Wrap code blocks with <pre lang="LANGUAGE" line="1"> and </pre> where “LANGUAGE”
is a GeSHi supported language syntax.
The line attribute is optional. More usage examples

Usage

Wrap code blocks with <pre lang="LANGUAGE" line="1"> and </pre> where “LANGUAGE” is a GeSHi supported
language syntax. See below for a full list of supported languages.
The line attribute is optional.

Example 1: PHP, no line numbers

<pre lang="php">
<div id="foo">
<?php
  function foo() {
    echo "Hello World!\\n";
  }
?>
</div>
</pre>

Example 2: Java, with line numbers

<pre lang="java" line="1">
public class Hello {
  public static void main(String[] args) {
    System.out.println("Hello World!");
  }
}
</pre>

Example 3: Ruby, with line numbers starting at 18

<pre lang="ruby" line="18">
class Example
  def example(arg1)
    return "Hello: " + arg1.to_s
  end
end
</pre>

Example 4: If your code already has html entities escaped, use escaped="true" as an option

<pre lang="xml" escaped="true">
&lt;xml&gt;Hello&lt;/xml&gt;
</pre>

Example 5: PHP, with line numbers and highlighting a specific line

<pre lang="php" line="1" highlight="3">
<div id="foo">
<?php
  function foo() {
    echo "Hello World!\\n";
  }
?>
</div>
</pre>

Example 6: PHP, with a caption (file and/or file path of the source file)

<pre lang="php" src"https://github.com/shazahm1/Connections/blob/master/connections.php">
<div id="foo">
<?php
  function foo() {
    echo "Hello World!\\n";
  }
?>
</div>
</pre><h3>Supported Languages</h3>

Styling Guidelines

WP-Syntax colors code using the default GeSHi colors. It also uses inline
styling to make sure that code highlights still work in RSS feeds. It uses a
default wp-syntax.css stylesheet for basic layout. To customize your styling,
copy the default wp-content/plugins/wp-syntax/wp-syntax.css to your theme’s
template directory and modify it. If a file named wp-syntax.css exists in
your theme’s template directory, this stylesheet is used instead of the default.
This allows theme authors to add their own customizations as they see fit.

Advanced Customization

WP-Syntax supports a wp_syntax_init_geshi action hook to customize GeSHi
initialization settings. Blog owners can handle the hook in a hand-made plugin
or somewhere else like this:

<?php
add_action('wp_syntax_init_geshi', 'my_custom_geshi_styles');

function my_custom_geshi_styles(&$geshi)
{
    $geshi->set_brackets_style('color: #000;');
    $geshi->set_keyword_group_style(1, 'color: #22f;');
}
?>

This allows for a great possibility of different customizations. Be sure to
review the GeSHi Documentation.

  • PHP, no line numbers.
  • Java, with line numbers.
  • Ruby, with line numbers starting at 18.

Встановлення

  1. Upload wp-syntax.zip to your WordPress plugins directory, usually wp-content/plugins/ and unzip the file. It will create a wp-content/plugins/wp-syntax/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.
  3. Create a post/page that contains a code snippet following the proper usage syntax.

Часті питання

Why is the plugin generating unexpected output?

Try editing code snippets without the visual editor. To turn off the visual
editor for all your edits, uncheck the visual editor checkbox in your profile.
Depending on what type of code you’re trying to display, you might also need
to disable WordPress’ corrections of invalidly nested XHTML (under Options ->
Writing).

Why can I, as an admin, post code snippets, but my authors cannot?

By default, WordPress filters HTML for particular user roles, and this affects
WP-Syntax’s input. As a workaround, install the Role Manager
plugin, and check “unfiltered HTML” for the roles that would like to post code snippets.

Works as documented. Easy way to have syntax highlighting for posts containing code. Thank you for developing this plugin!

https://linux-guru.azurewebsites.net/ My site has many code based articles for developers. Not much for WP as of yet but mostly for more general ideas for a custom web site from scratch. https://linux-guru.azurewebsites.net/location-based-advertisements/ is an article on SQL that I am working on, and this plugin has been able to get around some of problems with WP mangling code cut and paste does not get rid of the escaped code which is why I like that escaped switch which allows for clean SQL code that works safely

The Plugin installed and worked as expected, but if there were some customisation option it would be great the one i could think of is implementing the dark theme for the code preview which can be easily achieved by changing the style sheet.
29.09.2016
Its really good and easy to be used. Only thing is the style is to be improved. I am not the expert to change the default css for example to increase the padding of a line, it makes the backgroud crashed so I’ve given up.

The plugin is light weight and simple. Its style can be customized using CSS. Those who are looking for options in menus will have to look for another plugin
