Name:
Preserve Code Formatting
Author:

Version:
0.9
Last updated:

Description:

Preserve formatting for text within <code> and <pre> tags (other tags can be defined as well). Helps to preserve code indentation, multiple spaces, prevents WP’s fancification of text (ie. ensures quotes don’t become curly, etc).

Notes:

Bascially, you can just paste code into <code>, <pre>, and/or other tags you additionally specify and this plugin will:
* prevent all “wptexturization” of text (i.e. single- and double-quotes will not become curly; “--” and “---” will not become en dash and em dash, respectively; “...” will not become a horizontal ellipsis, etc)
* optionally preserve multiple spaces (including indentations) (for the most part, that is; it changes 2+ consecutive “\n” to “\n\n” and “\t” to ” “)

Keep these things in mind:
* ALL embedded HTML tags and HTML entities will be rendered as text to browsers, appearing exactly as you wrote them (including any
).
* By default this plugin filters both ‘the_content’ (post contents), ‘the_excerpt’ (post excerpts), and ‘get_comment_text’.

Example:
A post containing this within <code></code>:


$wpdb->query("
        INSERT INTO $tablepostmeta
        (post_id,meta_key,meta_value)
        VALUES ('$post_id','link','$extended')
");

Would, with this plugin enabled, look in a browser pretty much how it does above, instead of like:

$wpdb->query(”
INSERT INTO $tablepostmeta
(post_id,meta_key,meta_value)
VALUES (‘$post_id’,’link’,’$extended’)
“);
Installation:
  1. Download the file preserve-code-formatting.zip and unzip it into your /wp-content/plugins/ directory.
    -OR-
    Copy and paste the the code ( preserve-code-formatting.phps ) into a file called preserve-code-formatting.php, and put that file into your /wp-content/plugins/ directory. Please ensure you do not introduce any spaces or other characters before the <?php or after the ?>
  2. Optional: There are two settings in preserve-code-formatting.php file that you can customize:
    a. in the function c2c_preserve_code_formatting(), if you want other HTML (in addition to ‘code’ and ‘pre’) to be processed by this function, add them to the $tags array:
    $tags = array('code', 'pre');
    b. in the function c2c_prep_code(), if you do NOT wish for this plugin to help preserve spacing/indentation in the ‘code’/’pre’/etc tags, then set $use_nbsp_for_spaces to be ‘false’. If you decide to do this, you can still preserve code formatting via CSS. Here’s a snippet of what I use:
        
    code, pre {
  white-space: pre;
    }
  3. Activate the plugin from your WordPress admin ‘Plugins’ page.
Functions:

function c2c_preserve_code_formatting( $text )

  • $text : Text to be scanned for <code> and <pre> tags

function c2c_anti_wptexturize( $text )

  • $text : Text to be processed in such a way as to prevent wptexturize from doing its thing

[…] One of my intentions with this blog from the beginning was to post tracts of code in it. To this end, I promptly installed the Preserve Code Formatting plugin courtesy of Coffee 2 Code. Simple WordPress plugins are wonderfully easy to install: they are implemented as single PHP files that you copy into the wp-content/plugins directory under your WordPress installation, after which they will show up automagically as options under the Admin -> Plugins page where you can toggle them on or off.
