Hints and Tips

Purge wiki page cache

When changing templates, purge the browser & mediawiki cache. To purge the cache of a single page, add &action=purge to the URL (see [1] for more)

Keyboard shortcuts

• Reference page in wikipedia
• Page explaining how to change keyboard shortcut using user custom stylesheet.
• Most frequently-used HTML access keys (default access-key shortcut is alt+shift for Firefox and shift+Esc for Opera):

Action	Key
accesskey-edit	e
accesskey-preview	p
accesskey-save	s
accesskey-search	f

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" parameter
                if ( isset( $args['enclose'] ) && $args['enclose'] == 'div' ) {
                        $enclose = GESHI_HEADER_DIV;

                        // Since version 1.0.8 geshi can produce valid pre, but we need to check for it
                        $enclose = GESHI_HEADER_PRE_VALID;
                } 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.

Patch v0.2 → v0.3

The patch below 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.

RawFile-v0.2.patch (<file name="RawFile-v0.2.patch" tag="source">download</file>)

Patch v0.3 → v0.?

This patch allows for specifying the file anchor using an html class attribute instead of using {{#fileanchor}}. It also introduces a new syntax for file links, and allows for specifying the tag of the block to return (instead of returning the first encountered block after the link). For instance:

* '''Method 1''': Returns the block that immediately follows. Save [{{#file: method1.txt}} this file]: <code>Hello, World!</code>
: But this other example fails because of the <br> tag... So save [{{#file: method1-fail.txt}} this file]:<br>
:<code>Hello, World!</code>.

* '''Method 2''': Indicates the block(s) with anchors. Save [{{#filelink: method2.txt}} this file] (but not this <code>code text</code>):<br>
:{{#fileanchor: method2.txt}}<code>We can then</code> very easily {{#fileanchor: method2.txt}}<code>interleave wiki with downloadable text</code>

* '''Method 3''': Same as above, but using html attribute 'class'. Save [{{#filelink: method3.txt}} this file] (but not this <code>code text</code>):<br>
:{{#fileanchor: method3.txt}}<code>We can then</code> also very easily <code class="method3.txt">interleave wiki with downloadable text but with less typing</code>

* '''Method 4''': Same as method 1, but using new syntax (custom wiki tag). Save <file name="method4.txt">'''this''' file</file>: <code>Hello, World!</code>

* '''Method 5''': Same as above, but specifying which tag to include. Save ''<file name="method5.txt" tag="code">this file</file>'':
<source lang="text">This text is skipped.</source>
:<code>This is the text that will be returned...</code>

* '''Method 6''': Same as method 2 / 3, but using new syntax (custom wiki tag). Save <filelink name="method6.txt">this file</filelink>. Of course the old syntax <code>{{#fileanchor}}</code> for anchor is still supported.<br>
:{{#fileanchor: method6.txt}}<code>Again, we can </code> also very easily <code class="method6.txt">interleave wiki with downloadable text while using the new syntax</code>

This gives:

• Method 1: Returns the block that immediately follows. Save [{{#file: method1.txt}} this file]: Hello, World!

But this other example fails because of the <br> tag... So save [{{#file: method1-fail.txt}} this file]:

Hello, World!.

• Method 2: Indicates the block(s) with anchors. Save [{{#filelink: method2.txt}} this file] (but not this code text):
  

{{#fileanchor: method2.txt}}We can then very easily {{#fileanchor: method2.txt}}interleave wiki with downloadable text

• Method 3: Same as above, but using html attribute 'class'. Save [{{#filelink: method3.txt}} this file] (but not this code text):
  

{{#fileanchor: method3.txt}}We can then also very easily interleave wiki with downloadable text but with less typing

• Method 4: Same as method 1, but using new syntax (custom wiki tag). Save <file name="method4.txt">this file</file>: Hello, World!

• Method 5: Same as above, but specifying which tag to include. Save <file name="method5.txt" tag="code">this file</file>:

This text is skipped.

This is the text that will be returned...

• Method 6: Same as method 2 / 3, but using new syntax (custom wiki tag). Save <filelink name="method6.txt">this file</filelink>. Of course the old syntax {{#fileanchor}} for anchor is still supported.
  

{{#fileanchor: method6.txt}}Again, we can also very easily interleave wiki with downloadable text while using the new syntax
