@cindex yahtml

yahtml is a package to support creating HTML documents on Emacsens.  Easy
input of elements (tags) by completion, syntax checking with programs like
weblint, and invoking the appropriate browser or image viewer depending on
the cursor position is its main features.

(This Info is still incomplete)

@section Setting up yahtml

Add the following to @file{~/.emacs}

(setq auto-mode-alist
      (cons (cons "\\.html$" 'yahtml-mode) auto-mode-alist))
(autoload 'yahtml-mode "yahtml" "Yet Another HTML mode" t)
@end lisp

Next, add to load-path the directory with the yahtml files
(@file{yahtml.el}, @file{yatexlib.el}, @file{yatexprc.el}).  For example,
if you put them in @file{~/src/emacs/yahtml},

(setq load-path (cons (expand-file-name "~/src/emacs/yahtml") load-path))
@end lisp

is what you add.

By this, yahtml will be automatically loaded when editing files with .html
extensions.  "yahtml" will be displayed on the mode line if no errors

Examples for  @code{yahtml-path-url-alist}.  If @file{/home/yuuji/http/}
is @code{http://localhost/~yuuji} at home and @file{/usr/home/yuuji/www/}

@chapter Completion Input

Completion input of HTML elements is done through the same key strokes as
YaTeX's begin-type completion, section-type completion, large-type
completion, maketitle-type completion, and accent completion.
Corresponding elements in this order is; elements that span multiple
lines, empty elements such as img, tags that start and end in a
single line, elements with no attributes or contents, and special or
symbol entities.

@table @kbd
@item [prefix] b (YaTeX begin-type completion)
@end example

Completion for elements that the start tag and the end tag span multiple
lines. Mostly block-level elements.

@item [prefix] s (YateX section-type completion)
<img src="foo.gif" alt="photo">
@end example

Completion for elements that do not have end tags and require only
attributes.  Possible completions are, <img>, <input>.

@item [prefix] l (YaTeX large-type completion)

<big> 〜 </big>
@end example

Similar to begin-type completion but used for elements that start and end
on a single line.

@item [prefix] m (YaTeX maketitle-type completion)
@dots{} Completion for elements without attributes or contents.  Possible
completion is <br>

@item [prefix] a (YaTeX accent completion)
@dots{} Used to enter special or symbol entities.  By default completion
for < (&lt;), > (&gt;), & (&amp;), " (&quot;), ' (&apos;), blank (&nbsp;)
is possible.

@section td-enclosure/tr-enclosure
If you wan to convert series of field into <td>...</td> repetitions for
table element, td-enclosure or tr-enclosure is convenient.

@table @kbd
 @item [prefix] @}
	@dots{} Enclose each field in a region into <td>...</td>'s.
 @item [prefix] ]
	@dots{} Enclose each line in a region into <tr>...</tr>'s, with
        every line converted to <td>...</td> repetition.
@end table
They presume white space as field separator by default.
To change this, enter other delimiting character for a query.
You can convert CSV, for example, into table by specifying
comma(,) as a delimiter.

If you want to enclose fields with th, call with
universal-argument (@kbd{C-u}).  Enter `th' to enclose fields
with <th>...</th>.  The special answer `thd' means that
enclose the only first column with th, and the rest with td.

@section CSS class-name completion
You can input a class name in your CSS definition with completion.
If you have CSS defined as below;

@display, @{ background-color: 0xffffff; @}, @{ font-size: 120%; @}
@end display

when you input h1(or h2) tag with completing-read by [prefix] b or
[prefix] l, yahtml prompts you to input class name with completion from
the words which are effective to h1 or h2.  And if you defined
global class like this;

 .caution @{ font-size: 120%; background-color: 0xc00000;@}
@end display

when you input any tags via completing-read, yahtml prompts you to input
class name.  If this is bothering, typing @kbd{C-j} instead of
@kbd{RET} (or @kbd{C-m}) cancels the next prompt to class name completion.
