覆盖/工具提示在Emacs for Windows中是否正常工作？

Question

我在C#代码上使用Flymake,在Windows上使用emacs v22.2.1.

Flymake的东西一直很适合我.对于那些不知道的人,您可以阅读flymake的概述,但快速的故事是,flymake重复构建您当前正在后台处理的源文件,以进行语法检查.然后,它会突出显示当前缓冲区中的编译器警告和错误.

Flymake最初并不适用于C#,但是我"修补了它",现在效果很好.如果您在emacs中编辑C#,我强烈建议您使用flymake.

我唯一的问题是UI.Flymake很好地突出显示错误和警告,然后使用包含完整错误或警告文本的工具提示插入"叠加".如果我将鼠标指针悬停在代码中突出显示的行上,则会弹出叠加工具提示.

但正如您所看到的,叠加工具提示已被剪裁,并且无法正确显示.

Flymake似乎正在做正确的事情,它是覆盖部分似乎被打破.,叠加似乎做对了.这是错误显示的工具提示.

不要覆盖提示在Emacs的Windows正常工作？

我在哪里解决这个问题？

经过一些研究,我发现效果可以证明 (tooltip-show really-long-string)

它与叠加层或flymake无关.

Answer 1

我用tooltip-show上的defadvice解决了这个问题.

;; Reforms a single-line string ARG to a multi-line string with a max
;; of LIMIT chars on a line.
;;
;; This is intended to solve a problem with the display of tooltip text
;; in emacs on Win32 - which is that the tooltip is extended to be very very
;; long, and the final line is clipped.
;;
;; The solution is to split the text into multiple lines, and to add a
;; trailing newline to trick the tooltip logic into doing the right thing.
;;
(defun cheeso-reform-string (limit arg)
  (let ((orig arg) (modified "") (curline "") word
        (words (split-string arg " ")))
    (while words
      (progn
        (setq curline "")
        (while (and words (< (length curline) limit))
          (progn
            (setq word (car words))
            (setq words (cdr words))
            (setq curline (concat curline " " word))))
        (setq modified (concat modified curline "\n"))))
    (setq modified (concat modified " \n")))
  )

(defadvice tooltip-show (before
                         flymake-csharp-fixup-tooltip
                         (arg &optional use-echo-area)
                         activate compile)
  (progn
    (if (and (not use-echo-area)
             (eq major-mode 'csharp-mode))
        (let ((orig (ad-get-arg 0)))
          (ad-set-arg 0 (cheeso-reform-string 72 orig))
          ))))

结果:
