Numbers in paths do not support scientific notation. about svg HOT 6 CLOSED

There's a number parser in https://github.com/rust-lang-nursery/rustc-serialize/blob/master/src/json.rs#L1473 which I think is a solid implementation. Obviously it cannot be used as-is but it could be useful as a reference.

Thanks for the issue! Yes, scientific notation is in the grammar of path data, and it’s also in the grammar of basic data types you mentioned. The reason it’s not in consume_number is that, since I didn’t really need it, I decided to postpone it until later. It seems this later has come.

Fun story, the latest draft for SVG 2 lost the scientific notation in the path spec. I am pretty sure it wasn't intentional so I filed w3c/svgwg#286.

Hmm, that’s interesting. Let’s then wait and see what they have to say about that.

SVG 2 contains some major breaking changes from SVG 1.x. If you want to support SVG 2 specifically, I suggest creating a separate parser or adding a setting to the existing parser. All of the existing tooling is based on SVG 1.x, and it will be years before SVG 2 is finalized and some even small portion of the existing software moves to SVG 2.

I think that in order to be useful, this crate needs to at least be compatible with the 1.1 specification.

Yes, I absolutely agree.
