Consider the following Rust program:

fn main() {
    let s = String::new();
    s.ext|
}

When at the cursor (indicated with the |), invoking M-x counsel-company will insert the text extend after ext i.e., the third line becomes s.extextend.

The same behaviour happens in the following C program, but with a slightly different result: the prefix pu is replaced with pput.

#include <stdio.h>
int main(void) {
    pu|
}

What's your source of completions for C?

The variable company-backend is set to nil. Is that what you're looking for?

Not really. The completions have to come from somewhere. Which code produces the list, e.g. ("push", "pull", ...)?

I think you want to look at company-backends rather than company-backend. This is often a buffer-local variable, so look at its value in the relevant buffers.

It seems that removing the call to company-complete-common inside counsel-company eliminates the problem in the two example I provided. I don't yet know if it creates other problems elsewhere.

@gnuvince Thanks, please test.
