If you're using multiple shells like zsh and Elvish, then you might be interested in my proposal below for shell-agnostic autocompletion: https://news.ycombinator.com/item?id=19950892 https://news.ycombinator.com/item?id=19950892 I talked with the author of Elvish about it, and we both want it to happen, but are both working on other things now AFAIK. If you managed to write a working bash/zsh completion script, then kudos :) It's not easy. The basic idea is that shell completions could be both (1) shared among shells and (2) moved into the same language that the binary is written in (optionally).
