If you don't know Views UI, you will have a hard time understanding what all of this is about. If you don't know the basics of (PHP5) OOP, Views-style integration will look hairy. If you aren't used to module development, you will have a hard time understand why devs care about this.
Examples: - Flickr query plugin, - MongoDB Views integration Not EFQ query plugin including, but exists in contrib
Meaning it can be used in different places, or take input from the context, like the URL, or from the user Themability: the SemanticViews case So basically Views is a report builder. Just like Crystal Reports, but for Drupal. No (good) printing solutions.
Views introduced the concept early in Drupal, and it really caught the Drupal dev world with Drupal 6. This is really what Features is about But Features' Views integration, alas...
So you wanna talk to Views, eh ? Start by saying hello Other hook implementations will go elsewhere thanks to it.
Check: dr713.info dependencies = views dr713.module HVA
Views invokes these hooks only when the cache has been deleted. This being configuration information, it needn't be recomputed constantly.
Domain Specific Language: not /that/ true, but the idea comes from seeing similar constructs usually be done with INI, XML or JSON files, whereas Views uses format to skip on the user-space parsing logic PHPTemplate vs Xtemplate, PHPTal, Smarty... Also CCK content types And, of course Features / Ctools exportables
Actually, area handlers are really much like field handlers, so they contribute to the query in some abstract sense (although not technically)
Why ? Arguments themselves translate to conditions in the query. Defaults and validation do not translate to the query itself, but can inject parameters or prevent the query from being ran. views_content_cache attempts to invalidate content depending on actual activity, like comment/node updates and VotingAPI
Sample problem-space ordering: partial IPv4 addresses - not number: must be left aligned - not string Sample problem-space filtering - filter on month of date
This is not what actually happens in code, but it simpler to figure out that way.
