parse

SVG transform attribute parser.

This module parses SVG transform lists such as translate(10 20)rotate(30)scale(2). Commas are accepted where SVG allows separators, and adjacent signed numbers such as translate(10-20) are handled.

Types

Error

Errors returned while parsing an SVG transform attribute.

pub type Error {
  ExpectedClose
  ExpectedOpen
  ExpectedTransform
  InvalidArgumentCount(String, Int)
  InvalidNumber(String)
  UnexpectedToken(String)
  UnknownTransform(String)
}

Constructors

```
ExpectedClose
```
A closing parenthesis was expected.
```
ExpectedOpen
```
An opening parenthesis was expected.
```
ExpectedTransform
```
A transform function name was expected.
```
InvalidArgumentCount(String, Int)
```
A transform function received the wrong number of arguments.
```
InvalidNumber(String)
```
A numeric token could not be parsed as a float.
```
UnexpectedToken(String)
```
A token appeared where it is not valid.
```
UnknownTransform(String)
```
The transform function is not part of SVG’s supported transform set.

Values

attribute

pub fn attribute(
  input: String,
) -> Result(transform.Matrix, Error)

Parse an SVG transform attribute into a matrix.

Empty strings parse as the identity matrix.
