cross­word – Type­set cross­word puz­zles

An ex­tended grid-based puz­zle pack­age, de­signed to take all in­put (both grid and clues) from the same file. The pack­age can type­set grids with holes in them (for ad­ver­tise­ments, or other sorts of stuff), and can deal with sev­eral sorts of puz­zle: – The clas­si­cal puz­zle con­tains num­bers for the words and clues for the words to be filled in. – The num­bered puz­zle con­tains num­bers in each cell where iden­ti­cal num­bers rep­re­sent iden­ti­cal let­ters. The goal is to find out which num­ber cor­re­sponds to which let­ter. – The fill-in type of puz­zle con­sists of a grid and a list of words. The goal is to place all words in the grid. – Su­doku and Kakuro puz­zles in­volve fill­ing in grids of num­bers ac­cord­ing to their own rules.
For­mat may be block-sep­a­rated, or sep­a­rated by thick lines. In­put to the pack­age is some­what re­dun­dant: spec­i­fi­ca­tion of the grid is sep­a­rate from spec­i­fi­ca­tion of the clues (if they're nec­es­sary). The au­thor con­sid­ers this style both ‘nat­u­ral’ and ro­bust.
