我正在将我的工具链从R + TeXShop改造成我希望的更高效的Sweave - ＆gt; LaTeX - ＆gt; SyncteX - ＆gt; pdfview（skim）通过emacs（Aquamacs，具体）AUCTeX模式（使用emacs-speaks-statsitics'sweave minor-mode）。使用来自AUCTeX的SyncteX，一切都很好用 - ＆gt; pdfview链，从Sweave到.pdf的一切都很好。
当我添加Sweave作为第一步时，麻烦就出现了。 .Rnw文件现在成为主要原始文档，它生成的.tex文件只是一个中间步骤。当然，它是SyncteX锁定的.tex文件。
我对.emacs文件所做的唯一更改是注册两个新命令来从.Rnw构建.pdf。
有人可以提供有关如何让emacs使用SyncteX将输出.pdf同步到.Rnw而不是.tex的建议吗？
谢谢！
编辑1： 警告：这最终成为我整个下午摸索的总结。我非常接近解决方案，但最后因为我找不到文档的错误而被挫败。 警告2：今天是我第一次看到这个深入到emacs内部工作的任何地方。肯定存在错误或效率低下。
VitoshKa的回答让我大部分都在那里。将他的推荐添加到我的.emacs（嗯，Preferences.el，但功能相同）文件在启动时导致Symbol’s value as variable is void: noweb-minor-mode-map错误，因为Aquamacs似乎在其余的init文件之前加载了.emacs文件。
我通过在VitoshKa的(require 'ess-site) (require 'ess-eldoc)之前立即添加(define-key noweb-minor-mode-map (kbd "\C-c \C-c") 'Rnw-command-master)来修复此问题。不幸的是，Aquamacs的ess-swv.elc文件已经以二进制形式出货，迫使M-n P阅读器成为acroread。所以我将ess-swv.el文件的一部分的以下编辑添加到我自己的.emacs的底部：
(defun ess-makePDFandView ()
(interactive)
(setq namestem (substring (buffer-name) 0 (search ".Rnw" (buffer-name))))
(setq tex-filename (concat "\"" namestem "\".tex"))
(setq my-command-string (concat "pdflatex -synctex=1" tex-filename))
(shell-command my-command-string)
(setq my-command-string (concat "/Applications/Skim.app/Contents/MacOS/Skim \"" namestem ".pdf\" &"))
(shell-command my-command-string))
(define-key noweb-minor-mode-map "\M-nv" 'ess-makePDFandView)
现在，emacs将使用 M-n v 或 C-c C-c View RET 从emacs启动带有正确pdf名称的skim。还有一个障碍要通过......
命令转换 - 在emacs中单击尝试同步到filename.Rnw.pdf（但丢弃错误消息至少仍会导致pdfviewer中的正确同步）。 Command-Shift-在pdfviewer中单击以搜索源强制emacs打开filename.tex文件并同步到该文件。 Fortunately, Cameron Bracken has a fix for that。他只是不太喜欢emacs集成。
所以我将ess-swv.el进一步加入了我的.emacs：
(defun ess-swv-latex-rnw-sync ()
"Run LaTeX on the product of Sweave()ing the current file."
(interactive)
(save-excursion
(let* ((namestem (file-name-sans-extension (buffer-file-name)))
(latex-filename (concat namestem ".tex"))
(synctex-filename (concat namestem ".synctex.gz"))
(tex-buf (get-buffer-create " *ESS-tex-output*"))
(patchDVI-command-string (concat "Rscript -e \"library('patchDVI');patchSynctex('" synctex-filename "')\"")))
(message "synctex string: %s" patchDVI-command-string)
(message "Running LaTeX on '%s' ..." latex-filename)
(switch-to-buffer tex-buf)
(call-process "latex" nil tex-buf 1 "-synctex=1 " latex-filename)
(switch-to-buffer (buffer-name))
(display-buffer tex-buf)
(message "Finished running LaTeX" )
(message "Running patchDVI...")
(shell-command patchDVI-command-string))))
(define-key noweb-minor-mode-map "\M-nq" 'ess-swv-latex-rnw-sync)
认为缺少修补DVI并将其同步...但没有！ Command-Shift-Click上的相同行为如上所述...回到黑客攻击ess-swv。我删除了ess-makePDFandView函数，而是将以下内容添加到我的.emacs中：
(defun ess-swv-PDF-rnw-sync (&optional pdflatex-cmd)
"From LaTeX file, create a PDF (via 'texi2pdf' or 'pdflatex', ...), by
default using the first entry of `ess-swv-pdflatex-commands' and display it."
(interactive
(list
(let ((def (elt ess-swv-pdflatex-commands 0)))
(completing-read (format "pdf latex command (%s): " def)
ess-swv-pdflatex-commands ; <- collection to choose from
nil 'confirm ; or 'confirm-after-completion
nil nil def))))
(let* ((buf (buffer-name))
(namestem (file-name-sans-extension (buffer-file-name)))
(latex-filename (concat namestem ".tex"))
(tex-buf (get-buffer-create " *ESS-tex-output*"))
(pdfviewer (ess-get-pdf-viewer))
(pdf-status)
(cmdstr-win (format "start \"%s\" \"%s.pdf\""
pdfviewer namestem))
(cmdstr (format "\"%s\" \"%s.pdf\" &" pdfviewer namestem)))
;;(shell-command (concat "pdflatex " latex-filename))
(message "Running '%s' on '%s' ..." pdflatex-cmd latex-filename)
(switch-to-buffer tex-buf)
(setq pdf-status
(call-process pdflatex-cmd nil tex-buf 1 "-synctex=1 "
(if (string= "texi2" (substring pdflatex-cmd 0 5))
;; workaround (bug?): texi2pdf or texi2dvi *fail* to work with full path:
(file-name-nondirectory latex-filename)
latex-filename)))
(if (not (= 0 pdf-status))
(message "** OOPS: error in '%s' (%d)!" pdflatex-cmd pdf-status)
;; else: pdflatex probably ok
(shell-command
(concat (if (and ess-microsoft-p (w32-shell-dos-semantics))
cmdstr-win
cmdstr))))
(switch-to-buffer buf)
(display-buffer tex-buf)))
(define-key noweb-minor-mode-map "\M-nv" 'ess-swv-PDF-rnw-sync)
越来越近，但我们仍然需要告诉auctex要通过哪些文件名来浏览。所以我咬了一口子并编辑了auctex-config.el。我注释掉了现有的aquamacs-call-viewer函数定义，并将其替换为我自己的：
(defun aquamacs-call-viewer (line source)
"Display current output file as PDF at LINE (as in file SOURCE).
Calls `aquamacs-tex-pdf-viewer' to display the PDF file using the
Skim AppleScript protocol."
(cond
((string= (file-name-extension (TeX-active-master)) "Rnw")
(let* ((full-file-name
(expand-file-name
;; as in TeX-view
;; C-c C-c view uses %o (from TeX-expand-list), which
;; is the same.
(concat (file-name-sans-extension (TeX-active-master)) "." (TeX-output-extension))
default-directory))
(full-source-name
(expand-file-name
(concat (file-name-sans-extension (source)) ".Rnw") ;; this is relative to the master
(file-name-directory (full-file-name)))))
(message "full pdf name: %s" full-file-name)

还有一个最终测试（注意我将工具链的键绑定更改为：Mn s - > Mn q - ＆gt; Mn v依次为sweave - >＆gt; latex - ＆gt; view [注意这最后一个步骤你必须使用pdflatex而不是texi2pdf]），一切都建立，没有错误，启动观众......
"Skim" "/Users/myname/text/testing/myfile.pdf": exited abnormally with code 127.
现在我又完全迷失了。谁熟悉Skim？
编辑2：好吧，错误127只是在二进制文件中找不到文件。在那里的某个地方我必须破坏路径。所以我在我的auctex-config.el顶部附近添加了(setenv "PATH" (concat (getenv "PATH") ":" "/Applications/Skim.app/Contents/MacOS"))。现在一切都编译并启动没有错误......但是命令转换 - 点击emacs不会让Skim做出响应（至少它没有给出任何错误）。 Command-Shift-Click on Skim仍强制emacs打开.tex文件。
我想这已成为一个非常Aquamacs + Skim特定的问题，因为大多数其余的交互都是在AppleScript中，除非我错过了上面指出的lisp关键行中的明显内容。
答案 0 :(得分：3)
澄清。您希望来自Rnw文件的 C-c C-c 在Sweave的输出上运行AUCTeX命令（ M-n s ）。
问题是Auctex不知道它必须对不同的文件采取行动。这是如何让它意识到：
(defun Rnw-command-master (&optional override-confirm)
"Run command on the current document.
If a prefix argument OVERRIDE-CONFIRM is given, confirmation will
depend on it being positive instead of the entry in `TeX-command-list'."
(interactive "P")
(let ((TeX-transient-master (concat
(file-name-sans-extension (buffer-file-name))
".tex"))
(TeX-master nil))
(TeX-command (TeX-command-query (TeX-master-file)) 'TeX-master-file
override-confirm)))
(define-key noweb-minor-mode-map (kbd "\C-c \C-c") 'Rnw-command-master)
为了让Auctex首先运行sweave，需要一些额外的工作。 Noweb支持现在在ESS中得到了积极的重写，在下一个版本中，您将拥有一个全新的AucTeX集成系统以及默认激活的许多其他有用的东西。
