Extensions

SyntaxHighlight GeSHi

This extension adds the <source> tag to present formatted source code. See official page.

Restoring 1.0.7.# output - solving <pre> formatting problem

• Since at least version r24298 (July 21, 2007) (with GeSHi version 1.0.8), <source> tag does not match usual formatting applied for <pre> tags. This is because the extension applies by default the new GeSHi header style GESHI_HEADER_PRE_VALID. The following patch allows to restore the old formatting when there is no attribute line. It also introduces a new option valid to attribute enclose to force application of header style GESHI_HEADER_PRE_VALID

                        $enclose = GESHI_HEADER_DIV;

                        // Since version 1.0.8 geshi can produce valid pre, but we need to check for it

                } elseif( isset( $args['line'] ) ) {

• Example: the following code

After the following command, <source lang="bash" enclose="valid">  % cat ~/hello.c</source> you'll get the following output
<source lang="c">
#include <stdio.h>
int main(int,int)
{
  printf("Hello, World!\n");
  return 0;
}
</source>

gives:

After the following command, % cat ~/hello.c you'll get the following output #include <stdio.h> int main(int,int) { printf("Hello, World!\n"); return 0; }

• Another solution is discussed here. The proposed solution is to edit file "SyntaxHighlight_GeSHi.class.php". Go to line 192, which should look like

$css[] = ".source-$lang {line-height: normal;}";

Change this to

$css[] = ".source-$lang {padding: 1em; border: 1px dashed #2f6fab; color: black; background-color: #f9f9f9; line-height: 1.1em;}";

and you have restored the pre css formatting.

RawFile

RawFile is an extension made by Philippe Teuwen to allow downloading directly text in <pre> or <source> block as a file.

The following page adds an optional parameter to hook {{#filelink}}. With 1 param, the file is fetched from the current page as usual:

Save [{{#filelink: fstab }} this file] in your <tt>/etc</tt> directory.

With 2 param, the 2nd param is telling which page to fetch the file from:

Save [{{#filelink: fstab|Config files - fstab}} this file] in your <tt>/etc</tt> directory.
