Joomla! To highlight the source code (2)

Published on| April 25th, 2009 | No Comment.
Categories:Extension |


Description:
Previous (Joomla! To highlight the source code (1)), describe how the extension was a simple way of describing the basic source code in the article.

This time, to change the default color for each language, I would like to explain how easily.

As also previously described, Joomla! "Content - Code Hightlighter (GeSHi)" is, GeSHi is based.

GeSHi is, php is a class library.

GeSHi this will do to change the color definition.

So, you can change where and how the definitions can GeSHi colors, I would like to explain easily.

Reference (GeSHi online manual):

GeSHi color is defined?

GeSHi colors are defined, php files are written.

And temporary changes in color, php can be dynamically re-allocated, if you want to change the basic color, that will change the php file.

Php file that this file language (Language File) GeSHi and we call.

So, immediately, try to change the language file.

First, copy the file in real language, and then Save As appropriate

Cases)
php you want to change the color of the language.

Then, copy the following files in the same directory.

    /libraries/geshi/geshi/php.php

Copy the name here and we'll phplocal.php.

Now, phplocal that you have found the language.

Try it.

Described as follows: If you look like?

<pre xml:lang="phplocal">
$language_data = array(
    'LANG_NAME' => 'PHP',
    'COMMENT_SINGLE' => array(1 => '//', 2 => '#'),
    'COMMENT_MULTI' => array('/*' => '*/'),
    'HARDQUOTE' => array("'", "'"),
    'HARDESCAPE' => array("'", "\\"),
    'HARDCHAR' => "\\",
    'COMMENT_REGEXP' => array(
        //Heredoc and Nowdoc syntax
        3 => '/<<<\s*?(\'?)([a-zA-Z0-9]+?)\1[^\n]*?\\n.*\\n\\2(?![a-zA-Z0-9])/siU',
        // phpdoc comments
        4 => '#/\*\*(?![\*\/]).*\*/#sU',
        // Advanced # handling
        2 => "/#.*?(?:(?=\?\>)|^)/smi"
        ),
    'CASE_KEYWORDS' => GESHI_CAPS_NO_CHANGE,
</pre>

In fact, it looks like the following.

Indeed, php you will notice that the highlighted language the same way.

    'COMMENT_SINGLE' => array(1 => '//', 2 => '#'),
    'COMMENT_MULTI' => array('/*' => '*/'),
    'HARDQUOTE' => array("'", "'"),
    'HARDESCAPE' => array("'", "\\"),
    'HARDCHAR' => "\\",
    'COMMENT_REGEXP' => array(
        //Heredoc and Nowdoc syntax
        3 => '/<<<\s*?(\'?)([a-zA-Z0-9]+?)\1[^\n]*?\\n.*\\n\\2(?![a-zA-Z0-9])/siU',
        // phpdoc comments
        4 => '#/\*\*(?![\*\/]).*\*/#sU',
        // Advanced # handling
        2 => "/#.*?(?:(?=\?\>)|^)/smi"
        ),
    'CASE_KEYWORDS' => GESHI_CAPS_NO_CHANGE,

This way, you can create a personal language file easily.

First, make a copy, they would also like to backup the original php.php If you make changes to, GeSHi or updated, Joomla! To avoid overwriting of wrong when you update the It is also the order.

Later in order to facilitate maintenance, and a copy, I had better get into the file and copy it.

Let's change the color

Just copy files (phplocal.php) to make the changes, let's change the color.

Here, let's change the color of the comment as an example.

First, let's check the definition of the color of the comment.

Below, phplocal.php.

        ),
    'CASE_KEYWORDS' => GESHI_CAPS_NO_CHANGE,

Line 55: Definition of line comment line 56: The definition of multi-line comments.

This is what the character (string) which will define how the comments.

The color is not defined.

Let's change the color defined as follows.

1 =>: # 666666 -> # ff0000
2 =>: # 666666 -> # 00ff00
3 =>: # 0000cc -> # ffff00

This could change the color.

How do you think of the contents of the article here?

The direct way to handle the php file, some may feel the resistance.

However, in order to change the color, not to write complex programs.

1 and done, I know that you can simply change the color.

GeSHi can be a lot of things.

Joomla!, It does not use only a fraction GeSHi.

That is, start doing things the "easy" it may depart from the basic concept.

However, the human being involved in the development of more customized from the screen, I think it's good also.

Next time, I want to write a story around it.

Or a line number as above, it can change the color, GeSHi easy.

However, php is then controlled using the GeSHi class description I would like to be without the programming or if I say this in general.
