Janez Zemva <janezz55 at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |janezz55 at gmail dot com --- Comment #14 from Janez Zemva <janezz55 at gmail dot com> --- I need this feature for a jupyter lab c++ kernel, so I won't need to update the language version, as the standard is updated through the years. I think it could also be a handy shortcut to test whether old code compiles with the latest standard implementations. https://github.com/user1095108/jupyter-gpp-kernel The grepping and awking would add a delay and is not practical, as clang and gcc, for example, could have different supported standards.
