I'm getting some odd behavior in MinGW on Windows.

Every time I open emacs in the terminal emulator (emacs -nw), I find that when I close out of it that terminal has cleared itself.

For example, if I run mypy I get a list of Python type errors. Then I can open the offending code file and fix one of them, but then when I close out of it, I have lost the output of mypy and have to run it again to see the next error.

I've tried searching but I'm buried in results for how to keep the output of less after pressing q, but that's a question about less specifically whereas this is an issue with the terminal emulator itself.

I have found a bug report that seems to describe your problem :
Error list is cleared upon editing Rust file #1480.

When modifying Rust (.rs) files, the error list is cleared out until the file is saved. describe-variable says that flycheck-check-syntax-automatically is (save idle-change new-line mode-enabled). I have not set it manually; it is probably managed by spacemacs. For other languages/checkers, linting/error appears on the fly. I understand that checking/linting Rust is particularly expensive and that doing it on the fly is perhaps not desirable; I just want the error list not to clear when editing the file.

This bug was discussed from 2018 to 2020, but was never assigned to any developer. Its current status is "help wanted" (I'm not kidding) now in 2022.

I can see here these options for you :

  • Ensure that all the software packages involved are fully updated
  • Copy the errors list elsewhere before editing, to save it before it's cleared
  • Create a new bug report (with the details from your environment) and keep demanding for it to be solved.
