suckless.org werc setup

Background

At http://suckless.org we use a different werc setup. We believe that horizontal menus waste less screen real estate and scale generally better with different screen sizes, particularly on mobile device screens. The default layout requires approx. 16em for the side bar, the horizontal menu approach scales arbitrarily. One drawback with horizontal menus are directories with many entries, which reduces readability. On the other hand this limitation also enforces a carefully chosen structure with usually not more than 10 entries per directory (hence horizontal menu).

Differences

In contrast to default werc setups we use 9base instead of plan9port, and discount as markdown filter. We also use nginx as web server together with spawn-fcgi and fcgiwrap, in order to workaround nginx' limitation to only support fcgi (instead of cgi). Please see nginx.conf for further details.

We also modified the following files in order to make our menu approach working and we removed the top_bar.inc inclusion (look at the end to understand why).

lib/default_master.tpl

    % }
    % if not {
                <h1 class="headerTitle"><a href="/">%($"siteTitle%) <span id="headerSubTitle">%($"siteSubTitle%)</span></a></h1>

        }
    }

How it works

In order to generate the horizontal menu we overload werc’s default nav_tree function in etc/initrc.local and as referenced in above lib/default_master.tpl we also introduce a sites_menu list and a new nav_sites function that replaces the original top_bar.inc.

Using the new nav_sites function makes changes to top_bar.inc obsolete and allows us to highlight the active site.

We also introduced siteImage as an additional option for localised _werc/config files. If it is set we display an image instead of a site title for the selected site. See dwm.suckless.org for an example.
