I've been using a trick for allowing customizing CSS in the Approvals Workflow Plugin and in themes.
The trick proved to be very handy in a recent high-speed project with Headshift I just completed. The Designer was able to make last-minute CSS tweaks by simply updating an attachment. I would later update the theme's stylesheet.
The way it works is by using an attachment in the space's home page as an alternative stylesheet.
A helper checks if the attachment styles.css exists in the space's home page, and if so, it will return a link to if as a stylesheet, which is included in the HTML.
public class CssHelper {
private static final String CUSTOM_CSS_NAME = "styles.css";
private SpaceManager spaceManager;
public String getImportThemeCssLink(String spaceKey, String contextPath) {
Space space = spaceManager.getSpace(spaceKey);
if (space == null) {
return "";
}
Page homePage = space.getHomePage();
Attachment attachment = homePage.getAttachmentNamed(CUSTOM_CSS_NAME);
if (attachment == null) {
return "";
}
return "<link rel=\"stylesheet\" href=\"" +
contextPath + "/download/attachments/" +
homePage.getIdAsString() + "/" + CUSTOM_CSS_NAME +
"\" type=\"text/css\" />";
}
public void setSpaceManager(SpaceManager spaceManager) {
this.spaceManager = spaceManager;
}
}
it has to be defined in atlassian-plugin.xml:
<velocity-context-item key="cssHelper" name="Theme CSS Helper"
context-key="cssHelper"
class="com.headshift.confluence.css.helper.CssHelper"/>
In the main.vmd you can add the following at the end of the <head> section:
$cssHelper.getImportThemeCssLink($spaceKey,$req.contextPath)
That's it! the extra CSS will be included only if it exists.
