FAQ

What syntaxes are supported?

A wide range of programming languages syntaxes are supported. When you enter some code the syntax will be auto-detected, but you can be override this and select the syntax you wish use.

What happens if the service is turned off?

When you select to highlight some code a self-contained section of HTML is returned to Canvas and this is embedded in the page/document you are editing. If the service is turned off all your marked up sections of code will continue to work without any issues. The only functionality that will be lost is the ability to create new sections of highlighed code.

What does this cost?

The tool is free to install and use, we hope you find it useful.

Can the tool remember recently used languages and themes?

Yes. We will remember the last 5 used languages and the most recently used theme, however if you have configured your browser to block 3rd party cookies we are prevented from storing this information. If you wish to re-enable it either add an exception for code-highlight.wyelearning.com or re-enable 3rd party cookies.

How do I move the cursor out of the highlighted code in Canvas?

After you have inserted some highlighted code to the end of the document and you wish to type plain text afterwards you may find you can’t move the below the code. To resolve this move the cursor to the last line of the highlighted code and press shift+return. This should create a new line outside the code block and be using the styling of the text from before the code block was inserted.

How can I change the theme of existing code

  • In the Canvas rich text editor highlight the existing block of code.
  • With the code highlighted launch the code highlight tool.
  • The exisiting code should already be inserted into the textbox.
  • Select the new theme to use.
  • Click Update and the newly themed code should replace the existing code.
