Class

IpuzNonogram

Description [src]

class Ipuz.Nonogram : Ipuz.Grid
{
  /* No available fields */
}

A nonogram is a picture-based logic puzzle in which the player uses hints on the edge of the puzzle to reveal a picture.

Example of a nonogram Example of a solved nonogram

Nonograms can either be monochrome or have color groups. Monochrome puzzles are more common, but both are suppported. Color nonograms are represented by IpuzNonogramColor, which is a subclass of IpuzNonogram.

Representation

The IpuzCellType is used to determine whether an IpuzCell is filled in or blank. If it’s a BLOCK, then it’s filled in, while NORMAL indicates a blank cell. A NULL cell could indicate a shaped puzzle, though is not traditionally used with nonograms. In addition, the solution field is set to IpuzPuzzle:block, though can generally be ignored with monochromatic puzzles.

Other fields in the cell are undefined, as is IpuzStyle.

See IpuzNonogramColor for information on how color nonograms are represented.

Guesses

When used with an IpuzGuesses object, guesses are tested against the string IpuzPuzzle:block to indicate a block was guessed correctly. Since implementations will want to record additional information per-cell, any other guess string will be ignored.

Editing

Nonograms have one fix function — ipuz_nonogram_fix_clues(). This should be called after any changes to block polarity or grouping. It will update the internal clues and styles.

Note that not every grid can be uniquely solved as a nonogram. Some nonogram puzzles can result in multiple valid solutions. When creating a nonogram, care must be taken to be sure it’s solvable.

Note

Nonogram puzzles are currently a libipuz-only extension. As such, it’s not expected that any other program will be able to parse them.

Constructors

ipuz_nonogram_new

Returns a newly created nonogram puzzle.

Instance methods

ipuz_nonogram_fix_clues

Fixes the clues of self to match the current grid state.

ipuz_nonogram_get_cells_by_group

Returns all the cells that are set to group. For monochrome nonograms, the group should be IpuzPuzzle:block.

ipuz_nonogram_get_clues

Returns an array containing the run of IpuzNonogramClue indicated by index and direction.

ipuz_nonogram_get_group

Returns the group at index.

ipuz_nonogram_get_n_groups

Returns the number of different groups within self.

ipuz_nonogram_print

Prints self to stdout. This method is meant to be used for debugging.

Methods inherited from IpuzGrid (10)
ipuz_grid_check_cell

Invokes the operation determined by check_type on cell and guesses at coord.

ipuz_grid_create_guesses

Creates a fresh IpuzGuesses. It will be initialized to the current state of the grid.

ipuz_grid_fix_guesses

Fixes the guesses associated with self. The result will be a playable IpuzGuesses struct.

ipuz_grid_foreach_cell

Calls func for each IpuzCell in self.

ipuz_grid_get_cell

Retrieves the cell at coord. If the coordinates are outside the bounds of the grid then NULL will be returned.

ipuz_grid_get_guesses

Returns the IpuzGuesses associated with self.

ipuz_grid_get_height

Returns the number of rows in self.

ipuz_grid_get_width

Returns the number of columns in self.

ipuz_grid_resize

Resizes self to the new size.

ipuz_grid_set_guesses

Sets guesses for self. If there’s a mismatch in the cell types between guesses and self then FALSE is returned. guesses will be set regardless of the return value.
