"Hi, Sam here. I want to tell you about an exciting feature we are developing to bring more value to Boost libraries. Many libraries are using codecov.io to host coverage reports. This solution is better than nothing, yet codecov is a for-profit company and sometimes the decisions they make are not necessarily aligned with the needs of the libraries in Boost. The C++ Alliance has developed a convenient alternative: generate beautiful looking coverage reports using our gcovr templates, and then publish them yourself for free on GitHub Pages using our provided GitHub Actions scripts. Joaquin has deployed this solution for his in-development library "Hub" and you can see those reports: https://joaquintides.github.io/hub/develop/gcovr/index.html I've put together a set of instructions to help you achieve this functionality for your own repository: https://github.com/boostorg/boost-ci/blob/master/docs/code-coverage.md Thanks to Julio Estrada for developing the UI for the reports."

Run coverage reports using gcovr + github pages. No Codecov.

To explain more: imagine Codecov-like coverage reports, except they are built with an open source software tool "gcovr". Hosted on Github Pages, and you have potentially more control over the output, the steps, the appearance, etc. since the script is customizable.

Cool. Maybe I'm being stupid, but something I miss with this (and other similar tools) is the ability to skip forwards/backwards to the next uncovered line (and highlight it), is this something that might be possible? Many thanks for doing this though, it looks cool, and we'll try to try it out shortly. Best, John.
