Description

To highlight a code snippet, follow these steps:

  1. Insert a new Text Box (Insert -> Text Box)
  2. Copy and paste/write your code snippet into the text box (You can choose any fonts based on your preference)
  3. Select the text box
  4. Go to Tools -> Highlight Code -> <Language of the code>

That's it. Your code should be colored based on the syntax.

I have tested only a few languages. If you find any bugs, please report them at GiHub Issues.

Note: This extension uses pygments to color the code. Pygments does not highlight some languages properly. Therefore, you may not get the best outcome for some languages. Sorry for the inconvenience.

You may face Scripting Framework error in your system. It happens if LibreOffice is using a different (most probably an internal package) Python. Please check the following Git Hub issues to resolve them.

    Seems not to work under LibreOffice 6.4.3.2...
    Installation runs fine, but it keeps throwing errors when I'm trying to use it.
