//! Port of `_autocd` from `Completion/Zsh/Context/_autocd`.
//!
//! Full upstream body (5 lines verbatim):
//! ```text
//! sh:1 #compdef -command-
//! sh:2
//! sh:3 _command_names
//! sh:4 local ret=$?
//! sh:5 [[ -o autocd ]] && _cd || return ret
//! ```
//!
//! `_command_names` is ported (in `compsys::ported::_command_names`).
//! `_cd` is a sibling shell fn — dispatch via `exec accessors`. The
//! `AUTOCD` option is read directly from `zsh_h::isset`.
use crate::ported::exec::dispatch_function_call;
use crate::ported::zsh_h::{isset, AUTOCD};
/// `_autocd` — `-command-` context completion: command names + `_cd`
/// when the `autocd` option is set.
pub fn _autocd() -> i32 {
// sh:3 — `_command_names`. Route through the router (NOT a direct
// `_command_names(&[])` call) so an override — a plugin-registered one
// (ABI v4, `zmodload -R`) or the user's own `$fpath` copy — wins over
// the built-in Rust port, exactly as it would if `_autocd` were the
// shell function invoking `_command_names` by name.
//
// `dispatch_compsys` returns None when NEITHER a plugin nor the port
// handles the name, which now also covers "the port stepped aside for a
// user `$fpath` file" (router.rs `has_fpath_override`). Treating that as
// failure left command-position completion dead for anyone shipping
// their own `_command_names` — `pr<TAB>` produced nothing. Fall back to
// the normal shell dispatch, which autoloads the file from `$fpath`.
