For loops Updated Markdown page
Counting loops with for: from a number to a number, counting down, sequences, and typical uses such as star ratings, placeholders and page numbers.

Function reference Updated Markdown page
Every template function (the brace tags that control templates) of the template library and the kernel, with its syntax in one line and the page that explains it: def, set, if, foreach, for, while, do, switch, include…

Include Updated Markdown page
Splitting templates into parts with include: the design resource, passing parameters, what the included template sees, naming parts, and include versus node_view_gui and overrides.

-
Line view Updated Markdown page
The line view, the template of a content item in a list: what it receives, a teaser example with image, title, date and intro, parameters from the caller, headings inside lists, and per-class line views.

Literal and delimiters Updated Markdown page
Printing braces in template output with ldelim and rdelim, or a whole passage untouched with literal; why designs rarely need either now that CSS and JavaScript live in files.

Module result and content info Updated Markdown page
What $module_result holds after a view has run (content, path, title_path, uri, content_info, view_parameters, errorType and errorNumber) and how the pagelayout uses content_info to know the class, node, section, view…
-
Node templates by class Updated Markdown page
Organizing a design's templates per content class and view mode: the override rule pattern, a folder layout by view mode, a naming scheme, a checklist of the class and mode pairs a site needs, and how the media and…
