Article context: Global vs. local

The article is Txp’s main content type, making article context the basis for Txp site development. The primary tools for controlling article context are the article and article_custom tags.

This is an individual article page, meaning there is global article context. The article tag that displays this article contains, among other things, a title tag. title is context-sensitive, as I’ll show by dropping another one directly into the article body —

code:

<i style="color:green;">Now show the title: <b><txp:title /></b>!!!</i>

output:

Now show the title: Global vs. local!!!

Contrast this to the code below, which produces a short list of info/contact links. It also contains a title tag. But it shows different content, as you can see — clearly it has a different context.

This is an example of mixing global and local contexts. article_custom is not context-sensitive; it shows the same output in any context. But it is still a contextual tag, because it creates a new local article context for each article it finds, temporarily overriding any global article context. That is, article_custom is a context-setting tag. Once the article_custom tag is closed, this local context vanishes.

This code:

<txp:article_custom section="info" wraptag="dl" break="" class="contact-info">
	<dt><txp:permlink><txp:title /></txp:permlink></dt>
	<dd><txp:excerpt /></dd>
</txp:article_custom>

produces this output:
