Is it possible for a reader of articles on Habré to do code syntax highlighting, or can this be done only when writing an article?

Question

Habr

Please tell me in most of the articles on Habré the program code is presented. Part of it is backlit, part is not backlit and in font color format, etc. For example:

<font size="2" face="Courier New" color="black"><?php<br> require_once <font color="#A31515">'PHPUnit/Framework.php'</font>;<br> <br> <font color="#0000ff">class</font> StackTest extends PHPUnit_Framework_TestCase<br> {<br>     <font color="#0000ff">public</font> function testPushAndPop()<br>     {<br>         $stack = array();<br>         $<font color="#0000ff">this</font>->assertEquals(0, count($stack));<br> <br>        array_push($stack, <font color="#A31515">'foo'</font>);<br>         $<font color="#0000ff">this</font>->assertEquals(<font color="#A31515">'foo'</font>, $stack[count($stack)-1]);<br>         $<font color="#0000ff">this</font>->assertEquals(1, count($stack));<br> <br>        $<font color="#0000ff">this</font>->assertEquals(<font color="#A31515">'foo'</font>, array_pop($stack));<br>

is it possible to improve the readability of this (you need highlighting and display without html tags)
so far only one option is available: copying to an html file and previewing in the browser. There are other options, maybe some plugins. in general, to make it easier to read articles on Habré with code?

Answer 1

Plugin for Firefox , only it's not very good. The code is displayed in a separate window and is not very beautiful, there are not enough languages.
Well, you can also copy here:
