DpSyntaxHighlighterPlugin

Client side syntax highlighting using the SyntaxHighlighter

This plugin provides client side syntax highlighting using the SyntaxHighlighter by Alex Gorbatchev. JavaScript needs to be enabled on the clients web browser for this to work.

Syntax Rules

The code goes between the tags %CODE{...}% and %ENDCODE%.

%CODE{...}% can have the following parameters:

Parameter	Description
"..." or lang="..."	the programming language to be highlighted. see Supported Languages.
autolink="on"	prevent links in the highlighted code being clickable
collapse="on"	force code view to be collapsed
firstline="value"	begin line count at value; default value is 1
gutter="on"	enable or disable gutter
highlight="1,2,3"	highlight specific lines of code
smarttabs="on"	enable or disable smart tabs; note this will only work if there are tabs in your code.
tabsize="value"	wet the tab size for tab expansion; default value is 4; note this will only work if there are tabs in your code
padlinenumbers="value"	pads line numbers. possible values are false - don't pad line numbers. true - automaticaly pad numbers with minimum required number of leading zeroes. [int] - length up to which pad line numbers.
toolbar="on"	enable or disable the toolbar
quickcode="on"	enable code copy and paste from double click
light="on"	light mode: equavalent to turning off gutter and toolbar
htmlscript="on"	allows you to highlight a mixture of HTML/XML code and a script

Using DpSyntaxHighlighterPlugin With Other Syntax Highlighters

Currently all the Foswiki syntax highlighting plugins use the same %CODE% syntax. This allows you to switch the highlighter you use without having to update all your topics to the new syntax. However, it also means that if you have two or more highlighting plugins installed on your system, the plugin that is first in $Foswiki::cfg{PluginsOrder} (or by default, first alphabetically) will consume all the %CODE% blocks.

Version 1.2 of this plugin added support for using the %CODE_DP% syntax, which allows you to explicitly which plugin you want to highlight your code.

Clearly this is not the best solution to the problem of using more than one highlighting plugin. You can read the background on why this approach was taken in the task report.

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.

If the plugin is installed correcty, the following should be rendered:

/***********************************
 ** Multiline block comments
 **********************************/

$stringWithUrl = "http://alexgorbatchev.com";
$stringWithUrl = 'hello world';

ob_start("parseOutputBuffer");    // Start Code Buffering
session_start();

function parseOutputBuffer($buf) {
  global $portal_small_code, $portal_gzcompress;
  global $PHP_SELF, $HTTP_ACCEPT_ENCODING;

  // cleaning out the code.
  if($portal_small_code && !$portal_gzcompress) {
    $buf = str_replace("  ", "", $buf);
    $buf = str_replace("\n", "", $buf);
    $buf = str_replace(chr(13), "", $buf);
  }
}
