AWK Bowling

This is an implementation of the Bowling Kata in AWK.

Testing

To run the test suite located in the tests/ directory, simply run:

make test

This executes the test script located at scripts/test iterating over the files in the tests/ directory evaluating each test case for its expected score.

Tests are written in the format of:

-- -- -- -- -- -- -- -- -- ---,0
81 7/ 54 X  62 9/ 63 X  72 XX6,138

• A test case consists of a bowling game and expected score separated by a comma
• The bowling game is 10 space separated frames
• The first 9 frames all have 2 slots dedicated to the rolls
• The 10th frame has 3 slots
• In the case of a strike (X), the first 9 frames replace the second slot with a space. In the 10th frame, the throws simply fill each slot.
• When no pins are knocked down, it is represented by a dash (-)
• Spares are represented by the number of pins knocked down in the first slot followed by a slash (/) representing the rest of the pins have been knocked down

Installation

To install the script to your ~/.local/bin directory, run:

make install

Uninstall

Run:

make uninstall

Usage

This script is not designed for pretty output. At some point, I may add an option for more useful display.

Interactive

In interactive mode, the script will read from STDIN and print the result.

$ bowling
-- 7/ X  5/ 2- -- -- -- -- ---
54
81 7/ 54 X  62 9/ 63 X  72 XX6
138

One off

In one-off mode, you can pipe a bowling game into the script and the output will be printed.

$ echo 'X  1/ 2- -- -- -- -- -- -- ---' | bowling
34

# or

$ bowling <<< 'X  1/ 2- -- -- -- -- -- -- ---' 
34

File

Any file of test cases can be passed to the script and the result of each game will be printed in order

$ bowling ./tests/simple.txt
