How to create your own theme?

About

This page shows you how to create your own theme.

You can then apply advanced design and logic to your whole website application.

Theme introduction

Combostrap uses a theme system where:

• each page has its own template
• and each template is a Handlebars template that is rendered as HTML page.

Steps

Where is the default theme ?

The Combostrap default theme is located in this directory

dokuwiki_home/lib/plugins/combo/resources/theme/default

If you discover this theme, you will this layout directory:

• the directory pages that contains:
  • the templates directory that contains:
    • The handlebar templates (hbs file)
    • The template definition (yml file).
  • the partials directory that contains the partials. They are chunks of handlebar templates that can be included in templates.
• the directory components that contains:
  • the css directory that contains the stylesheet of each component
  • the html directory that contains the HTML templates of component

What are handlebar templates (hbs)?

Handlebar templates are files that are written in the following two languages:

• HTML
• and the handlebar templating language.

They get an array of data called a model and replace their value at runtime.

To simplify, the model is:

• The variable data
• The content in HTML.

If you want to get the whole model definition, contact us.

For instance, the following handlebars expression would be replaced with the page tile

{{ title }}

What are template definition files (yml)?

The template definition files contain properties that apply to the template.

For instance, if you want to use slot in your template, you need to define them.

The median template for instance contains 4 slot elements.

slots:
    - 'page-header'
    - 'page-footer'
    - 'main-header'
    - 'main-footer'

What are partials?

Handelbar partial are handlebars syntax that can be included and therefore reused in templates.

For instance, the below handlebars syntax will include the partial page-footer-partial.hbs that contains the footer of each template.

{{>page-footer-partial}}

What are components stylesheet?

A component stylesheet is a tiny CSS stylesheet that is applied when a component is used on your page.

It will overwrite the default styling of your bootstrap stylesheet.

Creation of your theme directory

Combostrap looks at themes in the directory combo/theme located in the data directory

For a standard dokuwiki installation, the directory is:

dokuwiki_home/data/combo/theme

If you name your theme, mytheme, you should then create the following directories

dokuwiki_home/data/combo/theme/mytheme
dokuwiki_home/data/combo/theme/mytheme/components/css
dokuwiki_home/data/combo/theme/mytheme/components/html
dokuwiki_home/data/combo/theme/mytheme/pages/templates
dokuwiki_home/data/combo/theme/mytheme/pages/partials

Selecting your theme

Now that you have created your theme directory, you can select it.

• Open the app configuration
• Search for the configuration combo-conf-005
• And select your theme

Creation of your first template

• Go to the default theme directory
• Copy the median template by transferring it into your custom template theme directory:
  • the file median.hbs
  • the file median.yml
• Rename them to
  • custom-median.hbs
  • custom-median.yml
• You should now have two files

dokuwiki_home/data/combo/theme/mytheme/pages/templates/custom-median.hbs
dokuwiki_home/data/combo/theme/mytheme/pages/templates/custom-median.yml

• Open the file custom-median.hbs and add modify the html header. Below we take over the page heading

<header id="main-header">
  <h1>Custom title: {{ title }}</h1>
</header>

Choose your new template for your page

• Open the page
• Choose your custom-median template in the metadata manager.

• And refresh your page by pressing F5
• The custom title was applied.

Next

From there, you can create any theme that suits your needs.
