How To Add Templates for New Formats to Existing Projects

By default projects creates with earlier versions of Helpinator has empty fields for the new formats and no specialized templates in them (For EPUB, MOBI and JavaHelp for example). So you need to add them manually.

First of all select “HTML-based templates” node in the project tree view and click “+” sign. “Add Template” dialog appears.

Add Template


Note the list of compatible formats under the “Built-in” templates drop-down list. When you select a template it shows what formats you can compile using it. Say, we need to add a template for EPUB format, so we select “epubmobi-default” template and click “OK”. Helpinator adds this template to the list of available templates.

Now you can select this template in the project options, “Templates” tab.

Helpinator 3.9 - Untitled (Unregistered)

Version 3.9: EPUB and MOBI

EPUB and MOBI are one of the most popular eBook formats. Now you can crate documentation in both of this formats using Helpinator.




Helpinator created EPUBs internally, but to compile MOBI you will need KindleGen utility from Amazon:

Download and install it then update Helpinator options (Main Menu->Tools->Options, “Compilers” tab).



Now you can compile MOBI format.

Note that you will need EPUB and MOBI format viewers to preview compiled documentation. You can use Kindle Previewer for both:


Version 3.9: QtHelp

To compile QtHelp you will need to download and install Qt SDK.

Note that we recommend to use version 4.8 and higher.

You will also have to change Helpinator Compiler options (Main Menu->Tools->Options, “Compilers” tab).



Then you can compile QtHelp file in one click:



Compiled QtHelp file looks like this:








Note that for testing purposes Helpinator automatically creates separate help file collection for your project.

Version 3.9: JavaHelp

From version 3.9 Helpinator supports JavaHelp output format. JavaHelp is a native file format (html and xml files packed as JAR file) and a set of tools that allow you to use JavaHelp in desktop and web applications written using Java.

You can learn more about this format from it’s webpage:


To compile JavaHelp you will need the following prerequisites

1. Java SE Development Kit

2. JavaHelp SDK


Install both then update Helpinator options (Main Menu->Tools-Options)




Then you can compile JavaHelp with a single mouse click:



Compiled JavaHelp help file looks like this:










Note that JavaHelp has outdated HTML viewer so only a subset of modern HTML features is supported. Therefore it requires it’s own HTML templates, templates for CHM/WebHelp/QtHelp are not compatible with this format.


To allow you to view resulting JavaHelp file Helpinator also compiles several supplementary files from JavaHelp SDK into the target folder.
