(use-package doom-modeline
  :ensure t
  :config
  (doom-modeline-mode 1))

(use-package flycheck
  :ensure t
  :init
  (setq flycheck-emacs-lisp-load-path 'inherit)
  (setq flycheck-check-syntax-automatically '(save mode-enabled idle-buffer-switch))
  (setq flycheck-buffer-switch-check-intermediate-buffers t)
  (setq flycheck-display-errors-delay 0.25)
  :config
  (global-flycheck-mode))

复现方法： 开两个窗口，分别打开来个不同的 elisp 文件， 然后多按几次保存

我估计是doom-modeline的锅，awesome-tab不会刷新modeline

loyalpartner commented 4 years ago

移除了 doom-modeline , modeline 也会闪 (setq flycheck-check-syntax-automatically '(save mode-enabled idle-buffer-switch)) 这个设置让flycheck 在切换buffer的时候之后执行检查，似乎flycheck 又会生成一个 flycheck_xxx.el 的文件并被emacs打开了

测试 emacs -Q 并只用awesome-tab，对比测试下，如果emacs -Q没问题就不是awesome-tab的锅

flycheck 里面如果设置了 (setq flycheck-check-syntax-automatically '(save mode-enabled idle-buffer-switch))， 会添加 buffer-list-update-hook， https://www.gnu.org/software/emacs/manual/html_node/elisp/Buffer-List.html#Buffer-List 里面提到 Functions run by this hook should avoid calling select-window with a nil norecord argument or with-temp-buffer since either may lead to infinite recursion.

解决办法就是： 在 (with-temp-buffer ...) 外面套上 (let (buffer-list-update-hook) (with-temp-buffer ...) )
