This fixes a regression where `zed -n .` in a subdirectory of an
already-open
project would redirect to the parent window instead of creating a new
one.
The root cause was that commit 66d2cb20c9 ("Adjust `zed -n` behavior")
made
`-n` run the worktree matching loop with subdirectory matching enabled,
when
previously `-n` skipped matching entirely.
## Changes
### Bug fix
- **Restore `-n` to always create a new window.** No worktree matching,
no
exceptions. This matches the behavior from when `-n` was first
introduced.
### New `--classic` flag
- Adds a hidden `--classic` CLI flag that explicitly selects the
pre-sidebar
default behavior: new window for directories, reuse existing window for
files already in an open worktree.
- The `cli_default_open_behavior` setting now toggles between `-e` (add
to
sidebar) and `--classic` behavior. When set to `new_window`, the classic
logic is used instead of unconditionally opening a new window.
### Refactor CLI open options
Replaces the old grab-bag of `open_new_workspace: Option<bool>`,
`force_existing_window: bool`, `classic: bool`, and `reuse: bool` with:
- **`cli::CliOpenBehavior` enum** — a single enum on the IPC boundary
with
variants `Default`, `AlwaysNew`, `Add`, `ExistingWindow`, `Classic`, and
`Reuse`.
- **`workspace::WorkspaceMatching` enum** — describes how to match paths
against existing worktrees (`None`, `MatchExact`, `MatchSubdirectory`).
- **`workspace::OpenOptions`** — uses `WorkspaceMatching` plus a simple
`add_dirs_to_sidebar: bool` instead of overlapping boolean flags.
The translation from CLI enum to workspace options happens in
`open_listener.rs`, keeping both layers clean and independent.
