It took me awhile to figure out how Hobo’s theming engine works. It’s not hard to create and use a new theme if you know the caveats.
We’ll start by using hobo’s default theme, clean, as a template. Go into RAILS_ROOT/app/views/taglibs/themes. You will see a directory called clean. Inside this directory is a single file called clean.dryml. You’ll want to pick a name for your theme. For this example, my new theme will be called red. Create a new directory called red and copy clean/clean.dryml to red/red.dryml.
We do not need to make changes to red.dryml for it to work properly. This file is where you will define tags, cards, and forms specific to your theme. If you need to pull in some more javascript and css, this would be the place to do it.
Next, we need go to RAILS_ROOT/public/hobothemes. Again you will see a clean directory. Copy this directory to a new one, red. Go to stylesheets within the red directory. Rename clean.css to red.css. Now we have the media assets for our new theme all set up. So how do we use this new theme?
Open RAILS_ROOT/app/views/taglibs/application.dryml. You’ll see a tag early on called set-theme. Just change that to point to red.
<set-theme name="red"/>If you are running your server, then restart now. Hobo will not load the new theme correctly otherwise. Now your blog its own theme!
