Lua translation ready for review !

Test code should be removed from preloaded: https://www.codewars.com/kata/reviews/5e935140955e440001e9ea1d/groups/6764af59f0e46282e42c620a

The best way! I keep forgetting that I don't need to explicity write true and false because the comparison operator always does that automatically for me.

either it was fixed at some point, or the report was wrong. C# sample tests are fine

your string is never nul-terminated because the line-ending logic has precedence over the nul-terminating logic in your if/else

dont use strcat() on uninitialized memory (e.g. that returned by malloc())

in R you want to require "\n" and not "\n" as the line separator if the aim is to create shapes in formatted strings:

cat("aaa\nbbb")

aaa

bbb

cat("aaa\\nbbb")

aaa\nbbb

You should probably mention the language you're talking about. If it was Rust, then it was fixed.

Not a kata issue.

O meu acontecia exatamente a mesma coisa, só que em Python

Approved

Fixed now then.

Approved.

The comments in the random tests are really not necessary. The code is self-documenting; the comments just distract there.

Please suppress the urge to code golf your test suite. join`` is just less readable than join("") - don't do it, write for readability and maintainability, CW can spare those couple of characters.

I would have commented this directly on the translation, but CW would not let me. It also shows two comments it isn;t actually showing. Something's very wrong there.
