- zt is a library that converts HTML page templates into Zig code at build time. According to the original post, using a nonexistent field or a type mismatch is reported as an error by the Zig compiler before execution. - Values are HTML-escaped by default, and the author states that URL attributes such as href and src are checked for dangerous schemes. To output raw HTML as is, it must be explicitly marked, like {!value}. - The author explains that output is written directly to std.Io.Writer and works without allocation. The original post also includes an example calling res.render from Dusty. - Block-level if, for, and switch are interpreted as Zig code, so ordinary sentences at the start of a line can become parse errors. The author wrote that they are considering a syntax such as @if instead.

The part saying that an if at the start of a line is caught as a parse error in the template syntax caught my eye first. Since I would have to wrap in an element the ordinary sentence I meant to put there, it will probably be tedious until I get used to it. However, catching field typos as build errors before running could be a practical difference for someone who edits templates often. I am curious how you would move existing templates if the syntax changes toward @if.
