是否有可能限制线是Emacs的编译缓冲区门店数量？ 我们的构建系统可以产生对整个产品产量建立的一些10000行，如果没有遇到任何错误。 由于我的编译缓冲区也ANSI解析色彩，这会造成非常，非常缓慢。 我想有只如2000输出的行缓冲。
Answer 1:
看来， comint-truncate-buffer效果一样好编译缓冲区因为它的外壳缓冲区：
(add-hook 'compilation-filter-hook 'comint-truncate-buffer)
(setq comint-buffer-maximum-size 2000)
我通过运行测试这个compile用命令perl -le 'print for 1..10000' 。 当它被完成，在编译缓冲区中的第一行是8001 。
Answer 2:
好吧，我坐下来写我自己的函数，它被插入到编译过滤器钩。 它可能不是最好的表演方案，但到目前为止，似乎很好地工作。
(defcustom my-compilation-buffer-length 2500
"The maximum number of lines that the compilation buffer is allowed to store")
(defun my-limit-compilation-buffer ()
"This function limits the length of the compilation buffer.
It uses the variable my-compilation-buffer-length to determine
the maximum allowed number of lines. It will then delete the first
N+50 lines of the buffer, where N is the number of lines that the
buffer is longer than the above mentioned variable allows."
(toggle-read-only)
(buffer-disable-undo)
(let ((num-lines (count-lines (point-min) (point-max))))
(if (> num-lines my-compilation-buffer-length)
(let ((beg (point)))
(goto-char (point-min))
(forward-line (+ (- num-lines my-compilation-buffer-length) 250))
(delete-region (point-min) (point))
(goto-char beg)
)
)
)
(buffer-enable-undo)
(toggle-read-only)
)
(add-hook 'compilation-filter-hook 'my-limit-compilation-buffer)
