Overview ¶
DayN is an empty day to be copy/pasted for a new day It contains an Init() function to load input, setup the day, and Run to run the puzzle

Functions ¶
func DensityColor ¶
DensityColor colors cells based on how many dots are on. 0 dots -> gray 1–2 -> blue 3–4 -> green 5–6 -> yellow 7–8 -> red
func GetBoardValue ¶
GetBoardValue returns a rune/int/bool at x,y in the input or the empty value if out of bounds
func ReadInputAsIntBoard ¶
read input as a series of rune lines
func ReadInputAsRunes ¶
read input as a series of rune lines
func RenderBraille ¶
RenderBraille renders a grid of bytes as a string of Unicode braille cells. grid[y][x] == 0 => pixel off, != 0 => pixel on.
func RenderBrailleWithColor ¶
func RenderBrailleWithColor(grid [][]byte, colorFn BrailleColorFunc) string
RenderBrailleWithColor renders a grid of bytes as a string of Unicode braille cells and uses colorFn to optionally wrap each cell in ANSI color codes.
grid[y][x] == 0 => pixel off grid[y][x] != 0 => pixel "on" with that value (used only by colorFn)
func ValidPosition ¶
Types ¶
type BrailleColorFunc ¶
BrailleColorFunc decides how to color a single Braille cell.
cellX, cellY: braille cell coordinates (0-based) in the output grid dots: 8 bytes, one per dot (1..8), 0 = off, non-zero = whatever was in grid
Return values:
fg: 0–255 for 256-color foreground, or -1 for "no fg color" bg: 0–255 for 256-color background, or -1 for "no bg color" ok: if false, RenderBrailleWithColor will render without any color

type Direction ¶
type Direction int
clockwise directions
func DirectionFromOffset ¶
func (Direction) OffsetMultiplier ¶
type Matrix ¶
type Matrix [][]byte
Matrix represents the board of cells on which the game is played.
type Option ¶
type Option func(*Options)
Option is a functional option type that modifies the Options.
type PositionDirection ¶
type Tetrimino ¶
type Tetrimino struct {
// Value is the character identifier for the Tetrimino (I, O, T, S, Z, J, L).
// This is used internally and may differ from the display representation.
Value byte
// Cells represents the shape of the Tetrimino as a 2D grid.
// True indicates a Mino is present in the cell, false indicates empty space.
Cells [][]bool
// Position tracks the coordinate of the Tetrimino's top-left corner in the game matrix.
// This serves as the reference point for all movement and rotation operations.
Position Point
// contains filtered or unexported fields
}
from https://github.com/Broderick-Westrope/tetrigo/blob/main/pkg/tetris/tetrimino.go A Tetrimino is a geometric Tetris piece formed by connecting four square blocks (Minos) along their edges. Each Tetrimino has a unique shape, position, rotation state, and rotation behavior defined by the Super Rotation System (SRS).
