gramatika VS template-benchmarks-rs

I wrote a lexer generator. It's pretty limited and poorly architected tbh, but feel free to have a look: https://github.com/dannymcgee/gramatika

I'm a huge nerd for programming languages and rendering, and to that end I've been putting together a general-purpose parsing library inspired by syn and using that to power a language server for WGSL.

I'm probably in the minority on this one, but I really hate writing verbose, repetitive code, so I freaking love macros. I will frequently use a one-off macro just to make something like a dispatcher function easier to read by cutting down on all the pomp and circumstance. I'm also working on a small crate that makes heavy use of proc macros, which I've already gotten a ton of mileage out of since it allows me to spin up a serviceable lexer with just a few lines of code. A lot of people really dislike macros because the source is hard to read and they're onerous to debug. They're not wrong on either of those points.

Any recommendations for rust template engines? I'd like something that can easily render labeled fragments of a template instead of requiring me to split a page into a dozen little files. Kinda like inline {{block}} definitions in Go's html/template. Speed is also nice.

From template-benchmark-rs [0] I found sailfish [1] (fast, but no fragments(?)). render-rs [2] and syn-rsx [3] (2022) both let you write html in rust macros which is cool (maybe that can substitute for fragments?). Then there's gtmpl-rust [4] which is just Go templates reimplemented in rust.

Personally, I'd recommend Maud if you don't need something with runtime reloading. Not only is it much faster, it implements a template language that is effectively the Rust-syntax equivalent to Slim or Haml using a procedural macro, so you get compile-time verification that your HTML output is well-formed.

I've been maintaining several benchmark repos based off of template-benchmarks-rs. I've noticed there are several other benchmark repos that are hard to know about.

I'm tempted to collect all of these benchmark repos into a github org to make them easier to find. So far I know of parser, md, argparse, and template languages.

Simple and straightforward. The only thing I'd change personally is using sailfish over markup. Seems to be the fastest templating engine?

As I said in my other post, runtime performance wasn't a concern for me except to catch anything egregious, like mini_markdown hanging. If people want to expand on this with different representative cases and criterion like template-benchmarks-rs, they are welcome to!

That's why I use Sailfish for server-side templating in my Rust web projects. It's ridiculously fast.

As for templating, here's a benchmark that can double as a list of candidates to choose from... though, again, Rust stuff tends to be fast, so don't assume that the slowest templating engine on a Rust-vs-Rust benchmark is going to be slow.

Yeah. You're much better off worrying about template rendering performance or database query optimization than the framework itself.
