Increase Timeout for Synchronization

$this->client = new IXR_Client($this->profiles[$this->profno]['server']);
$this->client->timeout = 60;

Add GeSHi Coloring

By default, dokuwiki uses only one template to render all the code highlighting. This is pretty restrictive given that GeSHi has language-specific highlighting. The guide on the dokuwiki page will show you how to create a CSS and load that up in order to get proper syntax highlighting in dokuwiki.

Batch-Edit Checked Boxes

Add checked="yes" to admin.php for batchedit to tick all the boxes matching the regex and replacement. Meant for the batchedit plugin.

$this->_ptln('<input type="checkbox" id="' . $id . '" name="apply[' . $id . ']" value="on" checked="yes"/>');

Enable Tikz for the LaTeX Plugin

The patch removes going through dvips and uses ImageMagick directly to convert dvi to png for the latex plugin.

Disable GeSHi Links

In inc/geshi.php or, on more recent Dokuwiki versions vendor/easybook/geshi/geshi.php, change:

    var $keyword_links = true;

to:

    var $keyword_links = false;

Preview Text Before Edit Form

Dokuwiki by default places the form before the preview text. This seems a little inconvenient because you are meant to pay attention at what you have written at the bottom of the page, such the having the preview window with the last lines of text at the bottom instead of on top (before your eyes) is not helpful. The following patch:

reverses that behavior, by editing inc/template.php and placing the preview text above the edit box.

Split a Large Page into Sub-Pages

The following PHP script reads a dokuwiki file (such as the ones under data/pages) and then splits the file into multiple smaller files by the title of the top-level title. The script only supports pages that contain top-level titles (in dokuwiki syntax, those pre-postfixed with six equal signs).

Using Tikz with Dokuwiki LaTeX Plugin

If you use Tikz with the Dokuwiki LaTeX plugin you may notice that it will generate very small images. This is due to the line:

$command = $this->_dvips_path." -E ".$this->_tmp_filename.".dvi"." -o ".$this->_tmp_filename.".ps";

in class.latexrender.php that tells dvips to attempt to generate an EPSF PostScript file from the DVI by drawing a tight bounding box around the text whilst ignoring graphics - and this is explicitly something that we do not want.

To remedy the situation, edit class.latexrender.php and change the former line to:

$command = $this->_dvips_path." ".$this->_tmp_filename.".dvi"." -o ".$this->_tmp_filename.".ps";

Upgrade Plugins for PHP 7 Compatibility

Change directory from the Dokuwiki root to lib/plugins/ and execute the following commands:

find . -type f -exec perl -p -i -e 's/&$handler/Doku_Handler $handler/g' '{}' \;

and:

find . -type f -exec perl -p -i -e 's/&$renderer/Doku_Renderer $renderer/g' '{}' \;

Password Recovery

In case of a lost password, add the following line to conf/users.auth.php:

admin:$1$4fd0ad31$.cId7p1uxI4a.RcrH81On0:DokuWiki Administrator:mail@host.com:admin,user

and then login using the username admin and the password admin.
