Where to start the porting?

[baldoalessandro]

Looking at the source of systemd I've found that tmpfiles use the function extract_many_words.

• source:
  • https://github.com/systemd/systemd/blob/539bcc831b67a047e4e19469eb4471fc4ea024b6/src/basic/extract-word.h
  • https://github.com/systemd/systemd/blob/4523f1db0fe6bce522281cb27d31b9af430c7b10/src/basic/extract-word.c#L230
• tests: https://github.com/systemd/systemd/blob/a859abf062cef1511e4879c4ee39c6036ebeaec8/src/test/test-extract-word.c#L490

Is this in your opinion a good starting point? I was thinking of porting this using nom, it is a good idea ?

nom is good, if you prefer bash opentmpfiles has an implementation.
