How can I align console output in Kotlin?

488 -> 488	| 485/500
489 -> 44499	| 486/500
490 -> 70070	| 487/500
491 -> 8838	| 488/500
492 -> 3444	| 489/500
493 -> 7888	| 490/500
494 -> 494	| 491/500
496 -> 992	| 492/500
497 -> 994	| 493/500
480 -> 60000	| 477/500
460 -> 2202020	| 496/500
499 -> 499	| 497/500
498 -> 996	| 495/500
495 -> 990	| 494/500
483 -> 966	| 480/500
500 -> 500	| 498/500
290 -> 11011010	| 499/500
430 -> 11011010	| 500/500

you can try use formatting like this: https://pl.kotl.in/gcsPhG1Mg

Thank you

[Valentin Metz]

Didn't notice I can just use Javas String-formatter :D

[deactivateduser]

best of both worlds 😃

[Valentin Metz]

Apparently

d != kotlin.ULong

Any idea what I'd use for unsigned longs?

[Valentin Metz]

So... apparently ULong can't print with %d...
It also doesn't have a .toBigInteger()...
So I need to:

number.toString().toBigInteger()

[Valentin Metz]

Works.. but seems rather inefficient.

print(
        String.format(
            "%-${range.toString().length}d -> %${ULong.MAX_VALUE.toString().length}d\t|\t%${range.toString().length}d / %d\n",
            number.toString().toBigInteger(),
            result.toString().toBigInteger(),
            counter.getAndIncrement(),
            range
        )
    )

[deactivateduser]

Not sure if there is equivalent formatting for ulong as Java doesn't have unsigned type. I used to use %ul in C, but it apparently not working here. Probably other folks here know about it ;)

You could probably just use %s instead of %d, hence number.toString() is enough, so there is no further conversion to big integer.

[deactivateduser]

for the format string, probably if its possible, can be extracted out as another variable, to reduce the string interpolation processing in every repetition

[Valentin Metz]

Yeah, in C/C++ I'd trust the compiler to get this, but in Java I wouldn't be sure about it.

[Valentin Metz]

On the other hand even doing this one million times wouldn't affect the runtime of the program much.

[deactivateduser]

Sure, if that's fine by you... The programmer decides 😉

[Valentin Metz]

In C I'd use a global for this. But I guess here I'd have no other choice than passing the variable at the function call?
