The rest of the code doesn't use whitespace to line up the = like that. Do you have an editor plugin that does it for you or do you have to do it manually? I'd be way too lazy for the latter :)

I use the easyalign-plugin for vim. The above alignment would be done in 3 keystrokes (after selecting the region of interest).

It sure is prettier, but I think it's bad. Say you add a fourth statement with a longer type and variable name, now you have to update 4 lines of code. If you just always use = then a single line of code won't involve changing others, keeping git diffs more readable. Yep, bad idea.

Plus having to select code and run the macro is also too much hassle, for it to be worth it (ignoring the source control issues) it would have to automatically detect consecutive assignments and update them all without needing any user selection.

Right. It's not important to me at all, I'd change that in a heart beat if it would stand in the way of the patch being accepted.

for (size_t i = start; i < end; i++) {
const char *selection = choices_get(state->choices, i);
if (selection) {
/* output the selected result */
printf("%s\n", selection);
} else {
/* No match, output the query instead */
printf("%s\n", state->search);
}
}

state->exit = EXIT_SUCCESS;
