unfortunately there is no ebook version and it seems araq is against publishing ebook (probably because of worrying about piracy) - for me who is travelling a lot, hard copy is a no go.

Araq has mentioned he'll create a new edition of the book for Nim 2.0, and publish it as an e-book, see https://forum.nim-lang.org/t/10366
