Improvements

CLI

• Print friendly error on how to look up the session id value when it is not detected or incorrect.
• Print friendly instructions to create a config file or env vars when the session id or passphrase isn't set.
• CLI command that prints out the configuration path

Advent of Code SDK

• Logging all the things
• Reject submissions for future dates automatically unless forced

Runner

• Use solver attribute for registration #[PuzzleSolver(day=,year=,part=)]
• Use example attribute #[Example(part_1="",answer=)]
• Support a "universal" solver fn (eg, both parts in one function)

Ube

Grid

• Add cols() and col(c) like the rows() and row(r) methods.

Point

• Add tests for EAST/NORTH/WEST/SOUTH constants.
• Convert zero(), one(), unit_x(), and unit_y() methods to be constants.
• Complete implementation for Point3.

Graph

• Move to standalone module.
• Support non-string keys.
• Support storing additional data in nodes.
• Add tests, documentation.
• Disallow $\d+ prefixed node names as they are reserved by the system.
• Optimize the builder by reducing hte number of string copies that are happening.
• Split graph module into submodules (graph, graph_builder, algorithms)

Misc

• Finish counter module.
  • Documentation.
  • Tests
• Finish union find module.
  • Documentation.
  • Tests
• Replace unwrap() and expect(...) with Option<T> and Result<T,E> for union_find.rs.
• Improve counter and union find implementations with fast hashing.

Bugs

• No warning for overwriting same day
• Should not fetch input before succesfully running examples
• AOC session should not be required until input or answer submission invoked

Missing Tests

• Client returns encryption error if cached input is encrypted with different password
• Client returns encryption error if cached input is (un)encrypted and password is (un)set

Solution Improvements

• Day 10
  • Grid neighbors(pt: Point2) -> Itr
