Before you try

I recommend you use the tagu crate instead of this crate.

Overview

Build xml / html / svg programmatically using element building blocks. Instead of using a templating engine, write data/markup that 'looks like' rust.

Find it on github and crates.io. Docs at docs.rs.

Tagger also provides functionality to build svg paths and polyline attribute data.

Tagger additionally protects against XML escaping by replacing xml escape characters with its encoded value.

Example

fn main() -> std::fmt::Result {
    let width = 100.0;
    let height = 100.0;

    let mut w = tagger::new(tagger::upgrade_write(std::io::stdout()));

    w.elem("svg", |d| {
        d.attr("xmlns", "http://www.w3.org/2000/svg")?;
        d.attr("viewBox", format_args!("0 0 {} {}", width, height))
    })?
    .build(|w| {
        w.single("rect", |d| {
            d.attr("x1", 0)?;
            d.attr("y1", 0)?;
            d.attr("rx", 20)?;
            d.attr("ry", 20)?;
            d.attr("width", width)?;
            d.attr("height", height)?;
            d.attr("style", "fill:blue")
        })?;

        w.elem("style", tagger::no_attr())?
            .build(|w| w.put_raw(".test{fill:none;stroke:white;stroke-width:3}"))?;

        w.elem("g", |d| d.attr("class", "test"))?.build(|w| {
            for r in (0..50).step_by(10) {
                w.single("circle", |w| {
                    w.attr("cx", 50.0)?;
                    w.attr("cy", 50.0)?;
                    w.attr("r", r)
                })?;
            }
            Ok(())
        })
    })
}
