A Rust library for writing SVGs. Can write any valid SVG-element. The result may be written to any file-like object. Function calls and variables are available.
A Rust library for writing SVGs. Can write any valid SVG-element.
The result may be written to any file-like object.
Function calls and variables are available.
Add the following to your Cargo.toml
svgmacro = "0.1.3"
To use the crate in your module, simply add: ```
extern crate svgmacro; ```
To use the macro, define a filelike object to store the result, and call the svg! macro. ``` use std::fmt::Write; // The write function to use, must be called Write (use lib::someWrite as Write;) let mut out = String::new(); // The object to write to
svg!(&mut out,
svg (width="100" height="100") [
circle (cx="50" cy="50" r="30")
]
);
Result written to out:
```
Define elements by their XML-tag, their attributes in a () and their children in a []. Parentheses and brackets are optional, these are all valid syntax. ``` svg () [] g [] circle () circle
svg (width="200" height="100") ["Hello world!"] g (size="20") ["Hello world!"] circle (cx="10" cy="10" r="10") ```
Nest elements by putting new elements inside the []-brackets of their parent. Add multiple attributes by delmimiting them with a space.
svg!(&mut out,
svg [
g(size="12" color="red") ["This is a group"]
g(color="red") ["This is a group"]
]
);
Handle variables and function calls by wrapping them in a {} closure, expressions with a @-symbol. ``` use std::fmt::Write; let mut out = String::new()
// Define your variables let width = "200"; let height = "100";
svg!(&mut out,
svg [
g(width={width} height={height}) [
"This is a group"
]
g [
{createcoolshape(&mut out)}
]
g [
@ for i in 0..3 {
let radius = 15;
svg!(&mut out, circle(cx="10" cy="10" r={radius}));
};
]
]
);
```
