You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: shared.rs
    path of file: ./repos/fish-shell/src/builtins
    
    the code of the file until where you have to start completion: use super::prelude::*;
use crate::builtins::*;
use crate::common::{escape, get_by_sorted
    
pub fn builtin_print_error_trailer(parser: &Parser, b: &mut OutputStream, cmd: &wstr) {
    b.push('\n');
    let stacktrace = parser.current_line();
    // Don't print two empty lines if we don't have a stacktrace.
    if !stacktrace.is_empty() {
        b.append(stacktrace);
        b.push('\n');
    }
    b.append(wgettext_fmt!(
        "(Type 'help %ls' for related documentation)\n",
        cmd
    ));
}
