Emacsを使い始めて、段々とその便利さがわかってきた。現在はLaTeXで修論を書いているのですが、LaTeXの打ち込みとコンパイルまでを一括して処理してくれています。

そんな感じで便利さを体感していると、なんと<a href="http://www.tsdh.de/cgi-bin/wiki.pl/doc-view.el" onclick="__gaTracker('send', 'event', 'outbound-article', 'http://www.tsdh.de/cgi-bin/wiki.pl/doc-view.el', 'EmacsでPDFを閲覧できる');" target="blank">EmacsでPDFを閲覧できる</a>ことを知りました。使ってみると、Windowsでは使えない文字で作業用ファイルを書き込もうとしていて、PDFが閲覧できませんでした(..;)どうにかならんのかと検索していたら、すでに他の人も作者の人に指摘済みでした（→<a href="http://www.mail-archive.com/gnu-emacs-sources@gnu.org/msg01114.html" onclick="__gaTracker('send', 'event', 'outbound-article', 'http://www.mail-archive.com/gnu-emacs-sources@gnu.org/msg01114.html', 'doc-view.el — View PDF/PostStript/DVI files in Emacs');" target="blank">doc-view.el — View PDF/PostStript/DVI files in Emacs</a>）:

Maybe use `temporary-file-directory’ or `make-temp-name’.

Probably not portable, I think.  Windows users may set the directory<br />to “c: ooar”.  Maybe you could do like the package formerly knows<br />as `tumme.el’ does it.  Ah, it’s `image-dired.el’ now:<br />`image-dired-thumb-name’.

,—-[ (info “(elisp)Directory Names”) ]<br />|    If you want to use a directory file name in making such a<br />| combination, you must first convert it to a directory name using<br />| `file-name-as-directory’:<br />| <br />|      (concat (file-name-as-directory DIRFILE) RELFILE)<br />| <br />| Don’t try concatenating a slash by hand, as in<br />| <br />|      ;;; Wrong!<br />|      (concat DIRFILE “/” RELFILE)<br />| <br />| because this is not portable.  Always use `file-name-as-directory’.<br />`—-
