Multi-word completion

[dozzes]

Is it possible to implement word by word completion with linenoise?
Lets assume we have commands:

command opt1 opt2
command opt3 opt4 opt5.
command opt7 opt8
command opt7 opt9

How can i organize completions to suggest for eaxample
"command" on typing any left substring of it then cycling through
next available options?

I hacked this in my programming language's repl

The basic idea is that when tab is pressed, I found the location of the last space, and made a copy of the input buffer, I would then use the first character after that space as the string to complete and append that to that temporary copy and refresh that new line. I would populate the completion list with local variables and all the keywords of the language.

I write some code in #115 to enable user to get cursor position from within the
completion code. Although I have not got the time to write an example of how to do the thing you want, but definitely you can implement that idea given the ability to get cursor position from within the completion callback.
