Hakyuu

The puzzle

Fill the cells of an area with numbers from 1 to SIZE of the area. If there are two cells with the same number N in a row or a column, there must be at least N cells between those two cells. Here’s a little self-explanatory example:

  • columns (5) specifies the number of columns in the grid

  • width (5.1cm) sets the width of the minipage, in which the grid is typeset

  • scale (1) scales the size of the grid in the minipage

  • cvoffset (-22pt) sets the vertical offset of the counters in the margin

Environments

hakyuu

The environment hakyuu is the central core of the style file. With the optional argument of the environment, you can reset the options with local scope. Here, a blank grid is created.

puzzlebackground

The puzzlebackground environment allows you to place elements behind the main layer. This is for example usefull for the fillarea command.

puzzleforeground

The puzzleforeground environment allows you to place elements in front of the main layer. This is for example usefull for the framearea command.

Commands

In the grid and around

hakyuucell

hakyuucell{column}{row}{number}

The command sets the {number} of the grid cell {column}{row}.

setrow

setrow{row}{csv list}

The command sets the contents of {row}. It expects a comma-separated list.

setcolumn

setcolumn{column}{csv list}

The command sets the contents of {column}.

framearea

framearea{color}{tikz path}

The command frames the area given by {tikz path} with color {color}. The reference for coordinates is the bottom left corner of the cell.

framearea{green}{(2,2)--(2,3)--(3,3)--(3,2)--(2,2)}

This command will color the frame of the grid cell (2,2) green. You should consider using this command in the puzzleforeground environment.

fillarea

fillarea{color}{tikz path}

The command fills the area given by {tikz path} with color {color}. The reference for coordinates is the bottom left corner of the cell. You should consider using this command in the puzzlebackground environment.

Presentation

definecounterstyle

The command allows you to define your own styles. For example, the style left is defined as follows:

To typeset the counter into the margin we use the command marginnote. We need to use the command reversemarginpar to set the counter into the left margin. Of course, we must use this command in a group for local scope. Finally we use puzzlecounter in a tikz node with a vertical offset set with the option cvoffset.

puzzlecounter

puzzlecounter

The command provides the counter in textual form to use it for example in definecounterstyle.

titleformat

titleformat{format}

With the command titleformat, you can define the format of the title. By default, the definition is as follows:

titleformat{centeringLargecolor{blue}}

Miscellaneous

hakyuusetup

hakyuusetup{options}

With the command hakyuusetup you can reset the options with global scope.

setpuzzlecounter

setpuzzlecounter{number}

With the command setpuzzlecounter, you can reset the puzzle counter, for example before the solutions.
