h2. Boards.xml quick tutorial

Open @boards.xml@, best is learn by example, so look at 4chan definition:

<pre><code class="xml">

<site>

	<name>4chan.org</name>

	<!-- Below is first-page board link look, eg.:

		http://boards.4chan.org/g/1

		http://boards.4chan.org/tv/1

		etc.,

		(first page may sometimes not work, but if you try /g/3 (as 3rd page) so you know that is good)

			@BOARD@ and @PAGE are required to specify. -->

	<board_url>http://boards.4chan.org/@BOARD@/@PAGE@</board_url>

	<!-- Below is link to thread, eg.:

		http://boards.4chan.org/g/thread/57704107

		looks similar? g - @BOARD@ and 57704107 is @TID@ - thread id

	... -->

	<board_url_topic>http://boards.4chan.org/@BOARD@/thread/@TID@</board_url_topic>

	<!-- Below is url to target image (not thumbinal), eg.:

		http://i.4cdn.org/g/1480199776841.jpg

		so g - @BOARD@, and 14801... is @FILE@ - easy?

	-->

	<board_url_img>http://i.4cdn.org/@BOARD@/@FILE@</board_url_img>

	<!-- Now more complex... below is regexp which allows app to recognize what is what in board

		MATCHED must be in first () - that may be little difficult, sorry for that

	-->

	<patterns>

		<!-- Link to topic (often it's "Reply" pattern) - it resolves to @TID@ -->

		<reply><![CDATA[<a href=\"thread/([0-9]{2,15})/?[a-zA-Z0-9-]+?\".?(class=\"replylink\")?>Reply</a>]]></reply>

		<!-- Resolves to @FILE@ - only filename - 1480199776841.jpg from our above example

			IMPORTANT: first match must resolves to filename and second match to extension

			so: 1480199776841.jpg -> 1: (1480199776841) 2: (jpg)

			dunno why i did that in past ;)

		-->

		<image><![CDATA[<a class=\"fileThumb\" href=\"//i\.4cdn\.org/[a-zA-Z0-9]+/([0-9]+)\.([a-zA-Z0-9]{2,5})\" target=\"_blank\">]]></image>

	</patterns>

	<!-- Below is boards on that chan

		Values are injected into @BOARD@ variable.

		-->

	<boards_list>

		<b>a</b>

		<b>b</b>

		<b>c</b>

		<b>d</b>

		<!-- ... -->

		<b>vp</b>

		<b>wsg</b>

		<b>x</b>

	</boards_list>

	<!-- That's all - easy as fuck, is it? -->
