"Lone" else lines are not properly indented about zig.vim HOT 4 OPEN

@matu3ba I think the issue is limited to if expressions. (An if statement would always start on its own line.) For example, this is a valid Zig program:

pub fn main() u8 {
    const retval = if (true)
        0
    else
        1;
    return retval;
}

from zig.vim.

Lone statements in an if else are grammar/parser errors, if on different lines
For example, I get on writing

fn somefn(num: c_int) void {
    if (num < 10)
        return 1;
    else
        return 2;
}

min.zig|4 col 5| : error: expected statement, found 'else'

This line neither works (only resolved types can be written into one line):

fn somefn(num: c_int) void {
    if (num < 10) return 1; else return 2;
}

Suggestion to close this.

UPDATE: Mention type resolving as working.

Is it fair to say that a lone else should always be de-indented? Is there a time when it should never be de-indented?

Ah, now I do understand the problem.
I think a proper solution requires a parser to distinguish expressions from statements, since those can be arbitrarily nested.

I can tell you that nvim-treesitter indent is broken for Zig and helix has also not implemented indentation based on treesitter yet.
