ingrid_core's Introduction

Ingrid Core

This crate contains the core crossword-solving code used in the Ingrid construction app, as well as a standalone binary that can be used to solve grids from the command line.

Usage

After setting up Rust, you can install the Ingrid Core CLI tool with cargo:

$ cargo install ingrid_core

Then you just need to provide a grid as an input file:

$ cat example_grid.txt
....#.....#....
....#.....#....
...............
......##.......
###.....#......
............###
.....#.....#...
....#.....#....
...#.....#.....
###cremebrulees

$ ingrid_core example_grid.txt

You can also use a custom word list (the default is Spread the Wordlist) or customize various other options:

$ ingrid_core --help

Acknowledgments

The backtracking search implementation in this library owes a lot to "Adaptive Strategies for Solving Constraint Satisfaction Problems" by Thanasis Balafoutis, which was helpful both as an overview of the CSP space and a source of specific implementation ideas.
The CLI tool includes a copy of the free Spread the Wordlist dictionary published by Brooke Husic and Enrique Henestroza Anguiano.

Flatpak build?

When downloading for Linux, only a .deb is available which doesn't work across all variants of Linux, unlike Flatpak which is much more widely supported. https://flatpak.org/
