対象とする人

小川版のpLatexを導入している人で、Emacs MuseでPDFを生成したい人
Emacsのデフォルト文字コードがshift-jisではない人

基本的な設定

Carbon Emacsでの設定例は以下のサイトが参考になります。

を参考にするといいです。特に「[hiro] muse-modeでpdf作成」では小川版のplatexを用いた関数が定義されているようなので、これを用います。

問題発生！

小川版のpLatexは文字コードとしてshift-jisしかダメなようです。でもそれだと、文字コードの違うtexソースは文字化けして、platexを通りません。結果的に、dviファイルが作成されずエラーが出てPDFが作れなくなります。

「[hiro] muse-modeでpdf作成」ではPDF作成用の関数を自前で定義しているようです:

(defun muse-latex-pdf-generate2 (file output-path final-target)
(muse-publish-transform-output
file output-path final-target "PDF"
(function
(lambda (file output-path)
(let ((command (format "cd \"%s\"; platex \"%s\";"
(file-name-directory output-path) file))
(times )
result)
;; XEmacs can sometimes return a non-number result. We'll err
;; on the side of caution by continuing to attempt to generate
;; the PDF if this happens and treat the final result as
;; successful.
(while (and (< times 2)
(or (not (numberp result))
(not (eq result ))
;; table of contents takes 2 passes
(file-readable-p
(muse-replace-regexp-in-string
"\\.tex\\'" ".toc" file t t))))
(setq result (shell-command command)
times (1+ times)))
(if (or (not (numberp result))
(eq result ))
t
nil))
(let ((dvi (muse-replace-regexp-in-string
".tex" "" file t t)))
(shell-command (format "cd \"%s\"; dvipdfmx \"%s\";"
(file-name-directory output-path) dvi)))
))
".aux" ".toc" ".out" ".log" ".dvi"))

単純にplatexを適切な回数分実行し、生成されたdviファイルをdvipdfmxに渡しているようです。

問題なのは生成されるtexファイルの文字コードがshift-jisではないことなので、以下の関数を定義してみました:

;; This function receives an argument and
;; it converts that file into shift-jis.
(defun generate_shiftjis (file)
(let* ((tempfile (expand-file-name (make-temp-file "tmp" nil ".tex")))
(cmd1 (format "cp %s %s" file tempfile))
(cmd2 (format "nkf -s %s > %s" tempfile file))
(cmd3 (format "rm %s" tempfile))
result)
(call-process shell-file-name nil nil t
shell-command-switch cmd1) ;    (shell-command cmd1)
(call-process shell-file-name nil nil t
shell-command-switch cmd2) ;    (shell-command cmd2)
(call-process shell-file-name nil nil t
shell-command-switch cmd3))) ;    (shell-command cmd3)

やっているのは

既存のtexファイル(文字コードがshit-jisではない)を一時ファイルに待避
nkfで待避ファイルをshift-jisに変換し、その結果を既存のtexファイルにリダイレクト
待避ファイルの削除

です。これをplatex実行前に行うようにしてみました。
