text::mediawikiformat::blocks
Text::MediawikiFormat::Blocks(3pm) User Contributed Perl Documentation Text::MediawikiFormat::Blocks(3pm)
NAME
Text::MediawikiFormat::Blocks - blocktypes for Text::MediawikiFormat
SYNOPSIS
None. Use Text::MediawikiFormat as the public interface, unless you want to create your own block type.
DESCRIPTION
This module merely creates subclasses of Text::MediawikiFormat::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::MediawikiFormat::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::MediawikiFormat::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.
