AoC2019 on Crystal

My solutions for Advent of Code 2019 by using Crystal language.

Done till day 5.

Structure

- aoc2019.cr/
  - exec/
    - day[DAY]_[PART].cr # source file to solve the specific quiz part.
    - day5.cr            # Both of part 1 and 2 in Day 5. 
  - spec/
    - day_spec/
      - day[DAY]_spec.cr # spec file for the quiz of that day
    - aoc2019_spec.cr    # default spec file for AoC2019 module made by crystal
    - spec_helper.cr     # default helper file made by crystal
  - src/
    - aoc2019/
      - day[DAY].cr      # implementation for the quiz of that day
    - aoc2019.cr         # the main source file of AoC2019 module

Test

Test for all days.

% crystal spec

Test for only one day.

$ crystal spec spec/day_spec/day1_spec.cr

Sorry, the spec file for day 5 was not produced.

Solve Quiz

Give your quiz input to exec/day[DAY]_[PART].cr as a text file or STDIN.

$ crystal build exec/day1_1.cr
$ ./day1_1 your_quiz_input_of_day1.txt

this same as above:

$ ./day1_1 < your_quiz_input_of_day1.txt

NOTE: Day 5 have only one source file to solve quiz and take no commandline paramerters. Part 1 and 2 will be identified by the input value, - 1 for part 1, 5 for part2.
