CodeColorer

Posted by Dmytro Shteflyuk on

CodeColorer is the plugin which allows you to insert code snippets into the post with nice syntax highlighting. I want to show you example first:

class Feed < ActiveRecord::Base

  SourceTypes = {
    :category => 0,
    :tag => 1
  }
 
  define_enum :source_type, :raise_on_invalid => true

  #-------------------------------------------------
  # Accessors

  def video_ids
    v = self[:video_ids]
    v ? v.split(':').map(&:to_i) : []
  end
end

Plugin based on GeSHi library, which supports most languages. CodeColorer has various nice features:

  • syntax highlighting in RSS feeds
  • syntax highlighting of single line of code (inline)
  • syntax highlighting of code in comments
  • line numbers
  • automatic links to the documentation inserting
  • code block intelligent scroll detection (short code would have short block, for long one block height would be fixed and scrollbar would appear)
  • predefined color themes (Slush & Poppies, Blackboard, Dawn, Mac Classic, Twitlight, Vibrant Ink)
  • syntax colors customization in CSS file
  • code protect from mangling by WordPress (for example, quotes, double-dashes, etc would look just right as you entered)

Installation

  1. Download and unpack plugin files to wp-content/plugins/codecolorer directory.

  2. Enable CodeColorer plugin on your Plugins page in Site Admin.

  3. Go to the Options/CodeColorer page in Site Admin and change plugin’s options as you wish.

  4. Use [cc lang="lang"]code[/cc] or <code lang="lang">code</code> syntax to insert code snippet into the post (you could skip lang="lang", in this case code would be in code block, but without syntax highlighting). Also you can use [cci lang="lang"]code[/cci] to format inline code (see the “inline” option description). The list of available languages you could find below.

  5. Have fun!

Syntax

To insert code snippet into your post (or comment) you should use [cc lang="lang"]code[/cc] or <code lang="lang">code</code> syntax. Starting from version 0.6.0 you could specify additional CodeColorer options inside [cc] tag:

1
[cc lang="php" tab_size="2" lines="40"]// some code[/cc]
Note: You should always use double quotes or single quotes around the parameter value. Boolean values could be passed using string true or false, on or off, number 1 or 0.

Short codes

Starting from CodeColorer 0.8.6 you can use short codes to insert code snippets. The short code in common looks like [ccMODE_LANG], where LANG is your programming language, and MODE is the one or more of following modes:

  • iinline
  • eescaped
  • sstrict
  • nline_numbers
  • bno_border
  • wno_wrap
  • lno_links

Small letter means enabled, capital – disabled. Examples:

PHP code with links enabled and line numbers disabled:

1
2
3
[cclN_php]
echo "hello"
[/cclN_php]

Already escaped HTML code:

1
[ccie_html]<html>[/ccie_html]

Ruby code without wrapping having tab size equal to 4:

1
2
3
[ccW_ruby tab_size="4"]
attr_accessor :title
[/ccW_ruby]

More examples could be found on the CodeColorer Examples page. You can find modes explained below.

Possible parameters

  • lang (string) – source language.
  • tab_size (integer) – how many spaces would represent TAB symbol.
  • line_numbers (boolean) – when true line numbers will be added.
  • first_line (integer) – a number of the first line in the block.
  • highlight (string) – a comma-separated list of line numbers to highlight (e.g. 1,5,8,9).
  • no_links (boolean) – when false keywords will be represented as links to manual.
  • lines (integer) – how many lines would be block height without scroll; could be set to -1 to remove vertical scrollbar.
  • width (integer or string) – block width.
  • height (integer or string) – height in pixels; used when lines number is greater then “lines” value.
  • rss_width (integer or string) – block width in RSS feeds.
  • theme (string) – color theme (default, blackboard, dawn, mac-classic, twitlight, vibrant).
  • inline (boolean) – when true forces code block to render inside <code></code> tag. Used to paste a single line of code into the regular text.
  • strict (boolean) – when true strict mode will be enabled. By default CodeColorer tries to guess whether strict mode is needed, so this option allows to force it on or off when automatic suggestion is wrong.
  • nowrap (boolean) – when false no horizontal scrollbar will be shown; instead code will be wrapped in the end of code box.
  • noborder (boolean) – when true no border will be shown around the code block.
  • no_cc (boolean) – when true the syntax in code block will not be highlighted, code will be rendered inside <code></code> tag.
  • class (string) – additional CSS classes to add to the wrapper HTML element.

You can use special tag [cci] instead of [cc] to force inline mode: [cci lang="lang"]code[/cci]

Most of these parameters could be configured via the CodeColorer options page.

Requirements

Plugin works with WordPress 2.7.0 – 2.8.2 as well. Hey users of WordPress 2.7.0, could you explain why do you use so old buggy crap? Use new one instead, at least it looks more beautiful!

Download

The latest version of the CodeColorer plugin is 0.9.11, and you can download it here:

version0.9.11DownloadCodeColorer Plugin

Also you can download older versions from plugin home page on WordPress.org (but do you really need this old stuff?).

Translations

Thank you all guys, who submitted translations to your language. CodeColorer is currently available in following languages:

Want to help me with translation? It’s easy!

  1. Install Poedit.

  2. Download codecolorer.pot file.

  3. Click File/New catalog from .pot file and select codecolorer.pop you’ve just downloaded.

  4. Enter project name (something like CodeColorer 0.9.8), your name and email address, select a language you want to translate to and click OK.

  5. Enter a filename like codecolorer-en_EN.po and click Save.

  6. Translate all strings one by one.

  7. Send me a .po file with a translation to [email protected]. Do not forget a link to add to CodeColorer project home page.

  8. Thank you!

To fix existing translation, just open corresponding .po file from codecolorer/languages folder in Poedit, and add missing or update existing strings.

Customization

Syntax coloring is highly customizable: you could change color scheme for all
languages or for specific language. You could find CodeColorer CSS in
wp-content/plugins/codecolorer/codecolorer.css file. To change colors for
all languages edit lines below Color scheme section.

There is simple mapping exists between Textmate color themes and CodeColorer
ones:

Добрый день.
Есть предложение насчет улучшения плагина.
Итак хотелось бы получить такой же функционал как и в этом плагине syntaxhighlighter-plus. Т. е. менюшки сверху и такуюже тему оформления defaut.
Насчет дополнения функционала можно просто скрестить 2 плагина – так получатся менюшки.
А как перенести тему defaut в CSS еще не знаю.

Great plug-in, really useful. Can I add a vote for width to be specified in percentage? If I make it look just right on the PC, mobile browsers have heart attacks ;)

said on May 5th, 2009 at 18:05 · Permalink · Reply

In codecolorer.php I would change

1
2
3
  function addCssStyle() {
        echo '<link rel="stylesheet" href="' . get_option('siteurl') . $this->pluginLocation . 'styles.php" type="text/css" />', "\n";
  }

to

1
2
3
4
5
6
  function addCssStyle() {
        if (trim(get_option('codecolorer_css_style'))!='')
                echo '<link rel="stylesheet" href="' . get_option('siteurl') . $this->pluginLocation . 'styles.php" type="text/css" />', "\n";
        else
                echo '<link rel="stylesheet" href="' . get_option('siteurl') . $this->pluginLocation . 'codecolorer.css" type="text/css" />', "\n";    
  }

because that way, the STYLES.PHP is only called if its really necessary.

And if I were you I wouldn’t store the additional CSS in the options at all but in an additional CSS-files because your “styles.php” requires “wp-load.php” and this takes a long time to load. And this only happens because you need the getoption-function.

Thank you very much for this beautyful plugin!

I’m getting it to work really fine in wordpress. With enthusiasm!

Some small observations:
Setting the tabsize to less than 4 in the options panel doesn’t seem to change it, it still shows “4” after a submit change and reload.
Then I think the stules for xml in the default theme write:

.twitlight .xml .re1 { color: #008080; }
/* Constant */
.twitlight .xml .re0 { color: #0080A0; }
– the exact same as in the twitlight theme.

Then actionscript3 misses the ‘extend’ method. I’ve written a comment on the SELD BE blog about it.

Any chance the themes not used could be ommitted in the loaded documents? It seems like a lot of css to load, then to override..

But this is fun and your plugin is wonderful!

regards and thanks
Kamilla

Hi there,

Was wondering if you could just make one small fix to your very useful plugin–

Change line 135 of codecolorer.php to:

1
$table = '<table class="line-numbering"><tbody><tr><td class="line-numbers"><div>';

Then add to codecolorer.css:

1
.line-numbering {border-collapse: collapse; padding:0px;

Or something semantically named like “line-numbering”.

I’m a bit of a nut of separating formatting from structure, even if it is not 100% clear yet on whether HTML5 will remove the cellpadding and cellspacing attributes (since the spec is still in draft), I still think it’s a good practice to follow it.

And this is just an idea but, although there are no namespaces in CSS, I wonder whether using “:” or “.” in the class name might help ensure that there were no collisions when including another CSS library. Of course, that’d be more work, but just an idea. Maybe prefix the attributes with “cc:” or something?

Thank you!

Sorry, I of course meant prefix the class attribute values, not the attribute (name).

Sorry for my double post.. i found other problem… in rss feeds i see code correcly only IE but Firefox and Opera have some problem to interpret it. Is problem for firefox and Opera or is problem the script?

an other one problem, i don’t know, but, now, i can’t set the height for block.. the block of code is equal to lines of code.. and not is equal at pixel can i set on administration panel. For example, before, in this page (http://codesnippet.altervista.org/conto-alla-rovescia-in-javascript/) i have the vertical scrool.. now, for only value in the height box, i see all code.

Thank you e sorry again for my english..

I’ve update it to 0.8 ,but i didn’t see style.php in my plugin.

So it didn’t work right,and i use the old version now..

said on July 14th, 2009 at 04:30 · Permalink · Reply

There is no need for styles.php now, because it really slows down the whole site. Instead plain old CSS file + a little of custom CSS in page head will be used. Hope you will appreciate it.

Also make sure you are installed 0.8.1 since 0.8.0 has weird bug with styles inclusion.

Hi Dmytro,

I found a bug in the latest version. In codecolorer-options.php, the following line:

1
update_option('codecolorer_tab_site', intval($_POST['codecolorer_tab_size']));

As you can see, its updating the ‘codecolorer_tab_SITE’ variable in the database instead of the ‘codecolorer_tab_SIZE’ variable. This makes it impossible to edit the default tab size in the codecolorer settings unless you manually edit the database entry. :-)

Oh I forgot to tell you thank you for the great library Dmytro! Its clearly the best syntax highlighter out there for WP.

You can use simple HTML-formatting tags (like <a>, <strong>, <em>, <ul>, <blockquote>, and other). To format your code sample use [cc lang="php"]$a = "hello";[/cc] (allowed languages are ruby, php, yaml, html, csharp, javascript). Also you can use [cc][/cc] block and its syntax would not be highlighted.
