input from stdin?

[jameson-m-jolley]

As far as I can tell, there is no good input method for stdin. I am new to UIUA, but I wanted to use it in a pipeline, and it seems there is no good way to take an input stream; the &sc function only reads one line at a time. I have tried to use do and repeat, but both functions complain about strings. I would like for this to be in the docs, as it's a standard thing people do in most languages

It's not a great solution, but for now, if you're having the same issues with &sc, you should use
$ cat file.txt |xargs uiua script.ua

Then, in your UIUA script

&args will box all the input that was printed to stdio

I know a lot of people do it, but the pipeline workflow is kind of foreign to me, so it's not something I've focused on making nice.
That said, the &rl modifier seems to be what you want. Admittedly it's docs are not great.
The code

&rl(&p$"Hi, _!") 0

Will continuously read lines from stdin and print a response as it goes.
