This package is built on top of the typed-svg package in Elm. It provides its own affine
transformation stack which tracks local-to-world and world-to-local coordinate transformations.
This allows:
- Easy transformation of mouse events to local coordinates.
- Geometry expressed in the local coordinate system.
- Consistent global line widths.
- Shortening paths to accommodate arrow heads.
This is implemented as a tree of nodes which are interpreted at render time to svg nodes.
Use elm-test and elm-verity-examples for testing:
elm-test
elm-verify-examples --run-testsFor local documentation preview, use elm-doc-preview
elm-doc-preview- Capture L2W transformation when events are declared, not when they are attached to objects.
- Text.
- "Bake" node.
- Refactor to separate out styles and events stuff from the huge main file.
- Use a non-recursive traversal of the graph.
- Need a way to draw items in world coordinates.
- Arrow heads.
- More examples.
