<[#ontology [kind topic] [cats Feature]]>
'''ExPar''' is a scripting language used by [[Kawachan]] to set metadata about a page or to invoke special functionality. This page explains how it can be used.

== Syntax ==
A ''block'' of ExPar code is surrounded by square brackets (<code>[]</code>). The ''root block'' – the block embedded directly into the page and not contained in any other block – is also surrounded by angle brackets (<code><></code>), so it appears as <code><nowiki><[...]></nowiki></code>.

Each block is made up of a list of ''tokens'', separated by spaces. These tokens may be either other blocks, or ''literals'' (plain text). The first token in a block is called the ''key''; all others are collectively called the ''values''.

There are two types of keys: ''command keys'' and ''parameter keys''. The difference is that command keys start with a hash sign (<code>#</code>) and parameter keys don't. If the key of a block is a command key, the block is called a ''command block''; similarly, if the key is a parameter key, the block is called a ''parameter block''.

The key of a block may be a literal or a command block, but it cannot be a parameter block. If the key is a command block, that command would first be executed to determine whether the parent block is a command or parameter block.

Command blocks are executed from inside to out, i.e. the most deeply nested commands are executed first. When a command block is executed, it returns a list of zero or more blocks, which are inserted into the parent block at the position of that command block. Of course, a command block may include other command blocks in its return value, which would be executed in turn, until no more remain.

The root block must be a command block, and must return a literal (though it can be the empty string). This literal will then be inserted into the page in place of the original ExPar code.

ExPar constructions will be parsed after template inclusions, but before wikilinks.

Links can still be inserted inside ExPar blocks, even though they both use square brackets. Because the string <code><nowiki>[[x</nowiki></code> is not legal anywhere in ExPar code (unless ''x'' is a hash sign or another opening square bracket), the ExPar parser will notice that this should be a link, and implicitly "escape" it for you. To insert an external link, simply use the same syntax as you would for a wikilink, for example <code><nowiki>[[http://example.com/|link text]]</nowiki></code>.

Keiji: remove superfluous version numbers, not sure about GPL

<[#ontology [kind topic] [cats Instance]]>
'''Kawachan''' is a [[wikipedia:Wiki|wiki software]] based off of [[mediawikiwiki:MediaWiki|MediaWiki]]. It is in development by [http://teamikaria.com/ Team Ikaria].

There have been two major releases thus far: [[Kawachan 5]] and [[Kawachan 6]]. Both releases kept the base MediaWiki engine.

The next planned version is [[Kawachan 7]], which will be a rewrite from scratch, not using the MediaWiki engine, but will still be based off of it (for example, MediaWiki skins will be retained).

There are no plans to ''publicly'' release versions 5 or 6, as the author feels the code is too hackish to be publicly released. However, from version 7 onwards, releases will be public and open source under a license to be chosen at a later date.
