Question

Rupert Swarbrick编写的现有代码，后来由Rory Yorke修改，仍然需要使用另存为函数指定文件位置（例如在OSX上，这将是ns-write-file-using-panel）。请问有没有人建议添加类似ns-write-file-using-panel的选项和/或修改脚本中写的/ tmp目录选项？

您可以修改最后一个函数，将文件名作为参数：

(defun print-to-pdf (pdf-file-name)
  "Print the current file to the given file."
  (interactive "FWrite PDF file: ")
  (let ((ps-file-name (concat (file-name-sans-extension pdf-file-name) ".ps"))
        (wbuf (generate-new-buffer "*Wrapped*"))
        (sbuf (current-buffer)))
    (jit-lock-fontify-now)
    (save-current-buffer
      (set-buffer wbuf)
      (insert-buffer sbuf)
      (setq fill-column 95)
      (longlines-mode t)
      (harden-newlines)
      (message (buffer-name sbuf))
      (spool-buffer-given-name (buffer-name sbuf))
      (kill-buffer wbuf)
      (switch-to-buffer "*PostScript*")
      (write-file ps-file-name t)
      (kill-buffer (current-buffer)))
    (call-process "ps2pdf14" nil nil nil ps-file-name pdf-file-name)
    (delete-file ps-file-name)
    (message "PDF saved to %s" pdf-file-name)))

您可能希望添加一些代码来测试PDF文件是否已存在，以避免覆盖任何内容。

使用`ns-write-file-using-panel`或类似选项将缓冲区保存为* .pdf
