Information

A simple CLI application that allows users to generate valid Skyscrapper boards.

Installation

Release Page

If you are on linux x86_64, you can download the latest version of this tool from the releases section on github.

Building From Source

If you have Rust installed on your machine, you can use the following commands to download and compile it into a binary file.

git clone https://github.com/nils-mathieu/skyscrapper-cli
cd skyscrapper-cli
cargo build --release

The result of that command will usually be located in target/release/skyscrapper-cli, but that might change if you have defined a custom target directory for Cargo.

Examples

Basic usage:

>_ ./skyscrapper-cli generate 4
  3 1 2 3
2 2 4 3 1 3
3 1 3 4 2 2
2 3 1 2 4 1
1 4 2 1 3 2
  1 3 3 2

It's possible to require a specific output format.

>_ ./skyscrapper-cli generate -o solution 4
4 1 3 2
3 2 4 1
1 3 2 4
2 4 1 3

>_ ./skyscrapper-cli generate -o header 4
  1 4 2 2
1         3
2         2
3         1
2         2
  3 1 3 2

>_ ./skyscrapper-cli generate -o both 4
  1 4 2 2
1 4 1 3 2 3
2 3 2 4 1 2
3 1 3 2 4 1
2 2 4 1 3 2
  3 1 3 2

>_ ./skyscrapper-cli generate -o header-line 4
1 4 2 2 3 1 3 2 1 2 3 2 3 2 1 2

You can even require multiple output formats at once.

>_ ./skyscrapper-cli generate -o header-line -o solution 4
1 4 2 2 3 1 3 2 1 2 3 2 3 2 1 2

4 1 3 2
3 2 4 1
1 3 2 4
2 4 1 3

If you want reproductible results, you can use the --seed option. Using twice the same seed will result in twice the same board.

>_ ./skyscrapper-cli generate --seed 12312323 5
  3 2 3 1 2
2 3 1 2 5 4 2
2 4 5 1 3 2 3
3 1 4 3 2 5 1
3 2 3 5 4 1 3
1 5 2 4 1 3 3
  1 4 2 3 2

>_ ./skyscrapper-cli generate --seed 12312323 5
  3 2 3 1 2
2 3 1 2 5 4 2
2 4 5 1 3 2 3
3 1 4 3 2 5 1
3 2 3 5 4 1 3
1 5 2 4 1 3 3
  1 4 2 3 2

It's possible to solve the skyscrapper problem using a given header-line.

>_ ./skyscrapper-cli solve "1 4 2 2 3 1 3 2 1 2 3 2 3 2 1 2"
  1 4 2 2
1 4 1 3 2 3
2 3 2 4 1 2
3 1 3 2 4 1
2 2 4 1 3 2
  3 1 3 2

Or check whether a given solution is valid or not.

>_ << EOF ./skyscrapper-cli check "1 4 2 2 3 1 3 2 1 2 3 2 3 2 1 2"
4 1 3 2
3 2 4 1
1 3 2 4
2 4 1 3
EOF
>_ echo $?
0
