Rupert Swarbrick提出了以下三个函数来将Emacs缓冲区打印到包含行的pdf(使用ps-print *函数时通常不会这样).
问题是这个功能是为了实现这种换行,必须制作当前缓冲区的副本.这有效地破坏了ps-print-buffer-with-faces在生成的PDF文件中每页顶部显示正确标题的能力.
作为他的解决方案的一部分,Rupert Swarbrick写了一个保留这些信息的函数.但是,生成的标头始终是HeaderLinesLeft
谁能发现错误?
(defun harden-newlines ()
(interactive)
"Make all the newlines in the buffer hard."
(save-excursion
(goto-char (point-min))
(while (search-forward "\n" nil t)
(backward-char)
(put-text-property (point) (1+ (point)) 'hard t)
(forward-char))))
(defun spool-buffer-given-name (name)
(load "ps-print")
(let ((tmp ps-left-header))
(unwind-protect
(progn
(setq ps-left-header
(list (lambda () name) 'ps-header-dirpart))
(ps-spool-buffer-with-faces))
(setf ps-left-header tmp))))
(defun print-to-pdf ()
"Print the current file to /tmp/print.pdf"
(interactive)
(let ((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 "/tmp/print.ps")
(kill-buffer (current-buffer)))
(call-process "ps2pdf14" nil nil nil
"/tmp/print.ps" "/tmp/print.pdf")
(delete-file "/tmp/print.ps")
(message "PDF saved to /tmp/print.pdf")))
最佳答案 试试这个:
(defun spool-buffer-given-name (name)
(let ((ps-left-header (list (format "(%s)" name))))
(ps-spool-buffer-with-faces)))
请参阅变量ps-left-header的文档,这是我上面提到的内容.
这是一个很好的能力;我肯定会使用它而不是ps-print.最好让它更像C-u M-x ps-print-buffer-with-faces;两个缺少的功能是标题中的目录名称,并提示用户输入文件名.两者都不太难.
