Somewhat of a weird addendum, but I actually only realized, you could port directly over like that, while writing the above comment.

Now I actually tried it on a 22 lines long shell script that I’ve been struggling with, and holy crap, I love it.

Like, I should say that I have always been (and likely will always be) shit at shell scripting. Any time I wanted to do a basic if, I had to look up how that works.
As a result, even those 22 lines were ripe with code duplication and I always felt really unsure about what will actually happen during execution.

Well, rightfully so. While porting over, I realized I had a bug in there, which has been annoying me for a while, but I always thought, well, it is a shitty shell script. I still remember thinking, I should probably not implement it like that, but then leaving it anyways, because I felt it would become unreadable with the shell syntax.

Now it actually feels maintainable, like I can even easily expand on it.
And I have to say that rust-script is really smooth. I barely notice that it’s compiling during the first run after changing the script file, and it’s fully cached afterwards, so it executes instantly.

I’ll still have to check for libraries that basically provide such a run() function/macro for me, but yeah, basically my threshold for not using shell scripts just dropped to any kind of control flow being involved.
