Handlebars-Sprig is a port of the Sprig template functions to the Rust programming language, with support for Rust's Handlebars library.
It does not aim to be 100% compatible with Sprig. Go templates and Go idioms might not feel right in Handlebars and Rust. But Handlebars-Sprig does aim to be close enough that it feels familiar.
Handlebars-Sprig was originally developed for, and is curently used in the Bartholomew Micro-CMS.
In your rust code, you need to register the handlebars helper functions:
```rust use handlebars::Handlebars; use handlebars_sprig;
fn main() { // Get a handlebars instance let mut hbs = Handlebars::new();
// THE IMPORTANT PART: Add the helpers
handlebars_sprig::addhelpers(&mut hbs);
// From this point, you can do whatever you want to do with the
// handlebars instance. It will have all of the functions available
// to the templates.
let tpl = "{{ add 1 2 }}";
// Example of running a template render.
let empty_context: Vec<String> = vec![];
println!("Template produced: {}", hbs.render_template(tpl, &empty_context).unwrap())
} ```
The above produces the following output:
console
$ cargo run --example basic
