Read a file line by line

How to stream one line at a time from a file?

Can you elaborate a bit more? This is hardly a question. The text file input transform will read a file line by line and output the data in rows. But I have no idea what your actual question is.

I need to report how many vowels each line of a file has. The file has no more specific format than to be UTF-8 encoded, and lines ending in \n (Unix style).

The Text File Input transform reads and outputs fields from text files line by line by default. If you want to read entire lines instead of separate fields, just set a separator of #@#@# or some other nonsense pattern that will never occur in the file, and (manually) specify a single String field (e.g line) in the fields tab.
