arnica

arnica is based on the ParserMarket/Gallery2 parser. It is an extension for MoinMoin 1.7 and 1.8.

The arnica extension gives you the opportunity to organize images and present them in your wiki. It supports some basic image processing operations by enabling an optional tool set. The action arnica_slides is used to play a slideshow of the selected images.

Installation

Download the arnica-1.7.1beta2.zip package file and upload it to your wiki. You can install it using the install dialog going to Attachments. Fur further informations on packages see HelpOnPackageInstaller. After installation and configuration (see next topic) the wiki needs to be restarted except for cgi deployment.

$/!\$ CopyThemeFile of PackageInstaller is currently just supported on standalone-like servers.

Separate htdocs theme files htdocs_arnica-1.7.1beta2.zip

1.8 installation

Because 1.8 supports multiple plugin directories, you can also, instead of downloading the zip files, just check out the repository:

cd /some/where
hg clone http://hg.moinmo.in/moin/1.7-extensions

and add the appropriate configuration option:

plugin_dirs = ['/some/where/1.7-extensions/data/plugin']

You still need to use the htdocs as above, but you can just symlink from the repository checkout into your web server's directory.

Configuration

The action and the parser are based on css. You have enter html_head into your wikiconfig.

html_head = '''
<link rel="stylesheet" type="text/css" charset="utf-8" media="all" href="%(url_prefix_static)s/arnica/css/text_x_arnica.css">
<link rel="stylesheet" type="text/css" charset="utf-8" media="all" href="%(url_prefix_static)s/arnica/css/arnica_slides.css">
''' % {"url_prefix_static": url_prefix_static}
