Good idea! I'll need to think slightly about the design, and in particular how to distinguish between an empty and full circle which would both be represented by equal starting and ending angles (relevant if being animated). This should also probably have a choice between being an open path or a closed pie slice.

Thanks for the consideration! Inkscape seems to have 3 ways of treating incomplete circles/ellipses:

I would love to take this on. Please assign it to me

@Forchapeatl Go for it! Feel free to suggest ideas for the solution to the problem I mentioned in my previous comment for telling the difference between an empty and full circle, but you could begin working on it while we experiment with ideas. Regarding @superlou's previous post, I think we can skip the "chord" option because that is redundant compared to just applying a "Close Path" node, which we don't have yet but you could also add. We don't do issue assignments until a PR is ready to land, but feel free to comment here with your PR number once you have it opened to communicate to others that you have a work in progress PR for the task. Looking forward to your PR!

I think this solution will work for the angle question: instead of "start angle" and "stop angle", it can be "start angle" and "angular distance" which can be a positive or negative value that tells it how far from the start angle to go. A full circle would be a full 360°.

Hi @Keavon , can we make modifications to these modifications

fn circle(_: impl Ctx, _primary: (), #[default(50.)] radius: f64, #[default(0.)] start_angle: f64, #[default(360.)] angular_distance: f64) -> VectorDataTable {
    let arc_path = Subpath::new_arc(DVec2::splat(-radius), DVec2::splat(radius), start_angle, start_angle + angular_distance);
    VectorDataTable::new(VectorData::from_subpath(arc_path))
}

to

? so that graphite Creates an arc based on the start angle and angular distance.

The documentation talks about the npm frontend build . With my little rust knowledge , I haven't found much information about building and testing the Rust backend . Please help me.

Revelant info from the discord: You can't create any shape which is not bezier curves. This is why circle is an approximated using bezier curves with link to some very large article. Also, even if I want to hack this, it's still impossible, since you can't create segment without a bezier handles. So in order to do this task one need to implement it using bezier curves

Algorithm for a bezier arc is here: https://github.com/GraphiteEditor/Graphite/blob/master/editor/src/messages/portfolio/document/overlays/utility_types.rs#L275

@Forchapeatl did you read and follow all the instructions in the contributor guide that you linked? It should cover all your questions about setting up the project.
