What is it

This project is easy tool which I have implemented to help print dates, component of which can produce a given sum. It implements two-digits sum like:

2012-12-12: 20+12+12+12=35

and one-digit sum like:

2012-12-12: 2+0+1+2+1+2+1+2=11, 1+1=2

It can help to find all dates in a range which have two-digits sum 35, or one-digit sum 2 for example.

How to run

The tool is written on Scala language and uses Gradle build system. To run ше without special knowledge Gradle wrapper can be used. But Some version of Java should be installed.

Help

To see command-line interface help:

$ ./gradlew run --args="--help"

Usage:
     hist
     list

Print histogram or dates

Options and flags:
    --help
        Display this help text.

Subcommands:
    hist
        Print histogram of dates count, 'hist --help' for details
    list
        Print list of dates, 'list --help' for details

So we have just two commands list and hist

list

$ ./gradlew run --args="list --help"

Usage:  list --dates <min:max> [--sum1 <integer>] [--sum2 <integer>] [--short]

Print list of dates, 'list --help' for details

Options and flags:
    --help
        Display this help text.
    --dates <min:max>
        Dates range in format yyyy-MM-dd:yyyy-MM-dd
    --sum1 <integer>
        Sum 1 Value 1-9
    --sum2 <integer>
        Sum 2 Value Positive
    --short
        Print short format

hist

$ ./gradlew run --args="hist --help"

Usage:  hist --dates <min:max> --sum <string> [--short]

Print histogram of dates count, 'hist --help' for details

Options and flags:
    --help
        Display this help text.
    --dates <min:max>
        Dates range in format yyyy-MM-dd:yyyy-MM-dd
    --sum <string>

    --short

Examples

$ ./gradlew run --args="list --dates 2022-01-01:2022-01-31 --sum1 2"

2022-01-04: 2+0+2+2+1+4=11, 1+1=2
2022-01-13: 2+0+2+2+1+1+3=11, 1+1=2
2022-01-22: 2+0+2+2+1+2+2=11, 1+1=2
$ ./gradlew run --args="list --dates 2022-01-01:2022-12-31 --sum2 66"

2022-01-23: 20+22+01+23=66
2022-02-22: 20+22+02+22=66
2022-03-21: 20+22+03+21=66
2022-04-20: 20+22+04+20=66
2022-05-19: 20+22+05+19=66
2022-06-18: 20+22+06+18=66
2022-07-17: 20+22+07+17=66
2022-08-16: 20+22+08+16=66
2022-09-15: 20+22+09+15=66
2022-10-14: 20+22+10+14=66
2022-11-13: 20+22+11+13=66
2022-12-12: 20+22+12+12=66

With option --short it prints only dates, without sum.

$ ./gradlew run --args="hist --dates 2022-01-01:2022-12-31 --sum one"
