This plug-in makes WP-Syntax highlighted code snippets downloadable from nice captions.

== Description ==

This plug-in adds download facility to
[WP-Syntax](http://wordpress.org/extend/plugins/wp-syntax/), putting a
pretty caption to each syntax highlighted code snippet, which contains
a permalink anchor and a couple of action buttons: "raw" and
"download".

The usage is easy.  You just put an attibute `filename="..."` to
a `<pre>` element and the snippet will have a caption.

I strongly recommend that you use the [TinyMCE Valid
Elements](http://wordpress.org/extend/plugins/tinymce-valid-elements/)
plug-in to make the non-standard attributes of the `<pre>` element
treated as valid and get preserved in the visual editor.  Configure it
so that the `pre` element can have the following attributes:

*   `class`
*   `dir`
*   `escaped`
*   `filename`
*   `highlight`
*   `id`
*   `lang`
*   `line`
*   `style`
*   `title`
*   `wrap`

You can alter the visual style of captions with CSS via admins menu.
This plug-in was first developed for PHP 5.2.12 and is currently
tested only with 5.4.  It will never work with PHP 4.

== Installation ==

1. Upload the `wp-syntax-download-extension` directory to the
   `/wp-content/plugins/` directory.

2. Activate the plugin through the 'Plugins' menu in WordPress.  Of
   cource you have to have WP-Syntax activated as well.

3. Add an attribute `filename="filename.ext"` to the `<pre
   lang="...">` snippet that you want to make downloadable.

4. Adjust the design of captions with CSS via admins menu.

== Frequently Asked Questions ==

Q.  This plug-in does not work with WP-Syntax _&lt;some old
    version&gt;_!

A.  No surprise.  This plug-in depends on WP-Syntax's internals.  Fix
    it yourself or upgrade WP-Syntax.

Q.  This plug-in does not work with WP-Syntax _&lt;the latest
    version&gt;_!

A.  Bad surprise to me.  This plug-in depends on WP-Syntax's internals.
    Fix it yourself or wait until I fix it.

Q.  How do you customize the styles of the code?

A.  Amongst the options I am using the [WP-Syntax
    Hacktify](http://wordpress.org/extend/plugins/wp-syntax-hacktify/)
    plug-in.
