I developed a code to show the coverage for specific C, C++ and Python files (Coverage is computed b using GCov). Now I can show the source code using Pygments. I have an array of covered lines and missed lines, I want to change the background of covered lines to green and background of missed lines to red. Is it possible to do that using Pygments?
You can achieve that by subclassing the HTMLFormatter. Out of the box the HTMLFormatter only supports line highlighting, but not in different colors as you need it. See https://pygments.org/docs/formatters/#HtmlFormatter for more details (scroll down to the subclassing part.)
