A path is a list of SubPaths.

Parse a path string into a Path

import Curve
import SubPath exposing (SubPath)


expected : SubPath
expected =
    Curve.linear [ (0,0), (42, 73) ]


parse "M0,0 l42,73"
    --> Ok [expected]

Only accepts valid complete subpaths (a sequences of a move followed by zero or more draws). Relative instructions are converted to absolute ones. Short-hand curve extensions are converted to explicit curve instructions.

The parser uses elm-tools/parser. The error type is Parser.Error.

Construct an svg path element from a Path with the given attributes

Turn a Path into a String. The result is ready to be used with the d attribute.

import Curve
import SubPath exposing (SubPath)


myPath : SubPath
myPath =
    Curve.linear [ (0,0), (42, 73) ]


Path.toString [ myPath ]
    --> "M0,0 L42,73"


-- forms a cycle (almost isomorphism) with parse
arc : String
arc = "M80,230 A45,45 90 0 1 125,275"


arc
    |> parse
    |> Result.map Path.toString
    --> Ok arc
