Hello @Freed-Wu,

thanks for the work!

Could you please add a test for that to https://github.com/andreasfertig/cppinsights/blob/main/tests/testSTDIN.sh? A test should also increase the code coverage again. Thanks!

In fact, this PR comes from https://github.com/Freed-Wu/cppinsights.nvim/blob/main/Insights_.cpp#L496 I hope it can provide an API for other project used: accpet input and return the result of converting.

Hello @Freed-Wu,

In fact, this PR comes from https://github.com/Freed-Wu/cppinsights.nvim/blob/main/Insights_.cpp#L496 I hope it can provide an API for other project used: accpet input and return the result of converting.

I like the idea.

I don't know whether I was imprecise. I'm happy to merge the PR once you add some tests for the new command line option. You can find the existing tests here: https://github.com/andreasfertig/cppinsights/blob/main/tests/testSTDIN.sh
Thanks!
