1887 such as ghostview, or want to preview its source which was drawn with
1888 other drawing tool, tgif for example. Then you should set entire regexp
1889 of including expression and enclose its file name part with \\\\( and \\\\).
1891 Ex. (\"\\\\\\\\epsfile{[^}]*file=\\\\([^,} ]+\\\\)\\\\(\\\\.e?ps\\\\)?[^}]*}\" 1)
1893 Where the first group surrounded by \\\\( and \\\\) is the file name part
1894 of expression. So you should set 1 to second element. And the first
1895 matching group is sent to (image) processor defined by the variable
1896 YaTeX-file-processor-alist. See also the documentation of
1897 YaTeX-file-processor-alist.
1899 ↑じゃ良くわかんないすね。例えば tgif hoge.obj して hoge.eps を
1900 \\epsfile{file=hoge.eps} でインクルードしているとしよう。その行で
1901 \[prefix\] g を押した時に tgif を起動して欲しかったら、まず上のような
1902 正規表現を設定する。\\\\(と\\\\)で囲んだところがファイル名になるように
1903 注意する。でファイル名部分が何番目の\\\\(\\\\)になるかをリストの2番目に書く。
1904 すると、その部分が変数 YaTeX-file-processor-alist で定義された
1905 処理プログラムに渡される。というわけ。
1906 ん〜やっぱりむずかしいね。分からない時は隣の Lisper に聞くか、
1907 fj野鳥の会で聞こう!
