I am using following solution for merge Git conflicts in Emacs, which is based on smerge. During merging smerge-mode creates <<<<<<< HEAD , ||||||||| parent lines for conflict detection.

But flycheck catches them as flycheck-error and changes their colors, hence they may become unreadable.

Would it be possible to prevent flycheck-mode to be disabled during merging or just can it ignore specific patterns to detected as flycheck-error' like: <<<<<<< HEAD`.

You can use M-x flycheck-mode to turn off flycheck in current buffer. Or alternatively, you can disable it for specific hooks (in this case smerge-mode):

(add-hook 'smerge-mode-hook (lambda () (flycheck-mode -1)))

*Note: I haven't tested this code yet. So, I don't know if this works or not.

  • Sorry for late response. I am getting Error running timer ‘lsp--on-idle’: (user-error "Flycheck mode disabled") error. After its disabled, it does not re-enable itself. Is it possible when smerge-mode is close automatically to re-enabe itself?
