Text::WikiFormat::Blocks(3pm)				User Contributed Perl Documentation			     Text::WikiFormat::Blocks(3pm)

NAME

       Text::WikiFormat::Blocks - blocktypes for Text::WikiFormat

SYNOPSIS

       None.  Use Text::WikiFormat as the public interface, unless you want to create your own block type.

DESCRIPTION

       This module merely creates subclasses of Text::WikiFormat::Block, which is the interesting code.  A block is a collection of related lines,
       such as a code block (text to display verbatim in a monospaced font), a header, an unordered list, an ordered list, and a paragraph (text
       to display in a proportional font).

       Every block extends "Text::WikiFormat::Block".

METHODS

       The following methods exist:

       o   "new( %args )"

	   Creates and returns a new block.  The valid arguments are:

	   o   "text"

	       The text of the line found in the block.

	   o   "args"

	       The arguments captured by the block-identifying regular expression.

	   o   "level"

	       The level of indentation for the block (usually only useful for list blocks).

	   o   "tags"

	       The tags in effect for the current type of wiki formatting.

	   o   "opts"

	       The options in effect for the current type of wiki formatting.

	   Use the accessors of the same names to retrieve the values of the attributes.

       o   "add_text( @lines_of_text )"

	   Adds a list of lines of text to the current text for the block.  This is very useful when you encounter a block and want to merge it
	   with the previous block of the same type

       o   "add_args( @arguments )"

	   Adds further arguments to the block; useful when merging blocks.

       o   "formatted_text()"

	   Returns text formatted appropriately for this block.  Blocks don't have to have formatters, but they may.

       o   "formatter( $line_of_text )"

	   Formats the $line using "Text::WikiFormat::format_line()".  You can add your own formatter here; this is worth overriding.

       o   "merge( $next_block )"

	   Merges the current block with $next_block (the next block encountered) if they're of the same type and are at the same level.  This
	   adds the text and args of $next_block to the current block.	It's your responsibility to remove $next_block from whatever your code
	   iterates over.

       o   "nests()"

	   Returns true if this block should nest (as in lists and unordered lists) for the active wiki formatting.

       o   "nest( $next_block )"

	   Nests $next_block under this block if the both nest and if $next_block has a level greater than the current block.  This actually adds
	   $next_block as a text item within the current block.  Beware.
