  "Revision number of running yatex.el")

;;;[Installation]
;;; 
;;; First, you have to install YaTeX and make sure it works fine.  Then
;;; put these expressions into your ~/.emacs
;;; 
;;; 	(setq auto-mode-alist
;;; 		(cons (cons "\\.html$" 'yahtml-mode) auto-mode-alist))
;;; 	(autoload 'yahtml-mode "yahtml" "Yet Another HTML mode" t)
;;; 	(setq yahtml-www-browser "netscape")
;;;      ;Write your favorite browser.  But netscape is advantageous.
;;; 	(setq yahtml-path-url-alist
;;; 	      '(("/home/yuuji/public_html" . "http://www.mynet/~yuuji")
;;; 		("/home/staff/yuuji/html" . "http://www.othernet/~yuuji")))
;;;      ;Write correspondence alist from ABSOLUTE unix path name to URL path.
;;; 
;;;[インストール方法]
;;;
;;; yahtml.el, yatexlib.el, yatexprc.el を load-path の通ったディレクト
;;; リにインストールしてください。その後、以下を参考に ~/.emacs に設定を
;;; 追加して下さい。
;;;
;;; 	(setq auto-mode-alist
;;; 		(cons (cons "\\.html$" 'yahtml-mode) auto-mode-alist))
;;; 	(autoload 'yahtml-mode "yahtml" "Yet Another HTML mode" t)
;;; 	(setq yahtml-www-browser "netscape")
;;;      ;お気に入りのブラウザを書いて下さい。netscapeが便利です。
;;; 	(setq yahtml-path-url-alist
;;; 	      '(("/home/yuuji/public_html" . "http://www.mynet/~yuuji")
;;; 		("/home/staff/yuuji/html" . "http://www.othernet/~yuuji")))
;;;      ;UNIXの絶対パスと対応するURLのリストを書いて下さい。
;;; 
;;;[Commentary]
;;;
;;; It is assumed you are already familiar with YaTeX.  The following
;;; completing featureas are available: ([prefix] means `C-c' by default)
;;;
;;;  * [prefix] b X	Complete environments such as `H1' which
;;;			normally requires closing tag `</H1>
;;;			<a href=foo> ... </a> is also classified into
;;;			this group
;;;			When input `href=...', you can complete file
;;;			name or label(href="#foo") by typing TAB.
;;;  * [prefix] l	Complete typeface-changing commands such as
;;;			`<i> ... </i>' or `<samp> ... </samp>'
;;; 			This completion can be used to make in-line
;;; 			tags which is normally completed with [prefix] b.
;;;  * [prefix] s	Complete declarative notations such as
;;;			`<img src="foo.gif">'
;;;			`<input name="var" ...>'
;;;  * [prefix] m	Complete single commands such as
;;;			`<br>' or `<hr> or <li>...'
;;;  * [prefix] p	Insert <p></p> on the point
;;;  * M-RET		Intelligent newline; if current TAG is one of
;;;			ul, ol, or  dl. insert newline and <li> or
;;;			<dt> or <dd> suitable for current condition.
;;;  * menu-bar yahtml	Complete all by selecting a menu item (Though I
;;;			hate menu, this is most useful)
;;;  * [prefix] g	Goto corresponding Tag or HREF such as
;;; 			<dl> <-> </dl>  or href="xxx".
;;;			Or invoke image viewer if point is on <img src=...>.
;;;  * [prefix] k	Kill html tags on the point.  If you provide
;;; 			universal-argument, kill surrounded contents too.
;;;  * [prefix] c	Change html tags on the point.
;;;			When typeing [prefix] c on `href="xxx"', you can 
;;;			change the reference link with completion.
;;;  * [prefix] t j	Call weblint on current file.
;;;  * [prefix] t p	View current html with WWW browser
;;; 			(To activate this, never fail to set the lisp
;;; 			 variable yahtml-www-browser.  Recommended value
;;; 			 is "netscape")
;;;  * [prefix] a	YaTeX's accent mark's equivalent of yahtml.
;;;			This function can input $lt, $gt or so.
;;; 
;;;[キーの説明]
;;; 
;;; 以下の説明において、特にカスタマイズをしていない限り、[prefix] は
;;; C-c キーを意味します。
;;;
;;;  * [prefix] b X	`</H1>' といった終了タグが必要となる`H1'のよう
;;;			な環境を補完入力します。<a href=foo> ... </a>
;;;			もこのグループです。
;;;			`href=...' と入力した後、TABキーを押すことで、
;;;			ファイル名や (href="#foo") のようなラベルも補完
;;;			できます。
;;;  * [prefix] s	以下のような宣言の補完を行います。
;;;			`<img src="foo.gif">'
;;;			`<input name="var" ...>'
;;;  * [prefix] l	`<i> ... </i>' や `<samp> ... </samp>' のよう
;;;			なテキストスタイル指定のタグを補完します。
;;;			この補完機能は通常 [prefix] b で補完できるものを
;;;			一行内で書きたいときにも用いることが出来ます。
;;;  * [prefix] m	`<br>' や `<hr> '、`<li>' 等の単体タグの補完
;;;			を行います。
;;;  * [prefix] p	カーソル位置に<p></p>を挿入します。
;;;  * M-RET		おまかせ改行; もしul、ol、dl等のタグ(リスト)を
;;;			使っている場合に、環境に合わせて改行と <li>、
;;;			<dt>、<dd>を入力します。
;;;  * menu-bar yahtml	選択したアイテムをメニューより補完できます。
;;;			(私はメニューが嫌いなんですが、htmlに関してはメ
;;;			ニューは一番ありがたいかも)
;;;  * [prefix] g	対応するタグ、<dl> <-> </dl> や href="xxx" の
;;;			ような TAG にジャンプします。
;;;			<img src=...> の場合はイメージビューワを呼び出
;;;			します。href=hoge.html の場合はhoge.htmlに飛びま
;;;			す。
;;;  * [prefix] k	ポイント上の HTML タグを消去します。
;;;			もし universal-argument を付けた場合(C-uを先に押
;;;			す)HTMLタグで囲まれた内容も同時に消去します。
;;;  * [prefix] c	ポイント上のタグを変更します。
;;;			`href="xxx"'の上で [prefix] c を利用した場合は、
;;;			参照しているリンクを補完機能を使いながら変更で
;;;			きます。
;;;  * [prefix] t j	カレントファイルに対して jweblint を呼び出しま
;;;			す。
;;;  * [prefix] t p	WWW ブラウザでカレントファイルを表示します。
;;;			(lisp変数 yahtml-www-browser の設定をお忘れな
;;;			く。お推めは "netscape" で、ねすけの場合既にねす
;;;			けが起動されていた場合そのねすけに Reload 命令を
;;;			送るという芸当が出来ます。ただし今のところX版の
;;;			ねすけちゃんだけ)
;;;  * [prefix] a	YaTeX のアクセント記号補完と同じです。
;;;			&lt; &gt; 等が入力できます。
;;; 
;;; [謝辞]
;;; 
;;; fj野鳥の会の皆さんには貴重な助言を頂きました。また、下に示す方々には
;;; 特に大きな協力を頂きました。あわせてここに感謝申し上げます。
;;; 
;;;	* 横田和也さん(マツダ)
;;;		マニュアルの和訳をして頂きました。
;;;	* 吉田尚志さん(NTT Data)
;;;		Mule for Win32 での動作のさせ方を教えて頂きました。
