Shell completion support for aopt framework.

Example

use std::ffi::OsString;
use std::path::PathBuf;

use cote::prelude::*;
use cote::shell::get_complete_cli;
use cote::shell::shell::Complete;
use cote::shell::value::once_values;
use cote::shell::CompletionManager;

#[derive(Debug, Cote)]
pub struct Cli {
    /// Print debug message
    debug: bool,

    /// Set the count value of cli
    count: Option<i64>,

    /// Set the files of cli
    #[arg(alias = "-f")]
    files: Vec<PathBuf>,
}

fn main() -> color_eyre::Result<()> {
    color_eyre::install()?;

    match get_complete_cli() {
        Ok(cli) => {
            if cli.write_stdout("fput", "fput").is_err() {
                cli.complete(|shell| {
                    let mut ctx = cli.get_context()?;
                    let mut completion = CompletionManager::new(Cli::into_parser()?);

                    shell.set_buff(std::io::stdout());
                    completion.set_values(completion.optset().find_uid("--count")?, ["42", "56"]);
                    completion.set_values(
                        completion.optset().find_uid("--files")?,
                        once_values(|_| {
                            Ok(["files/a.txt", "files/b.txt", "files/c.txt"]
                                .map(OsString::from)
                                .into_iter()
                                .collect())
                        }),
                    );
                    completion.complete(shell, &mut ctx)?;
                    Ok(())
                })?;
            }
        }
        Err(_) => {
            let cli = Cli::parse_env()?;

            println!("doing normal cli things..: {cli:?}");
        }
    }

    Ok(())
