Closes #ISSUE it is was still in [discussion](https://github.com/zed-industries/zed/discussions/37983) Release Notes: - Added: `--reuse` (`-r`) CLI flag to replace the workspace in an existing window instead of opening a new one This PR adds a new `--reuse` (`-r`) CLI flag that allows users to replace the workspace in an existing Zed window instead of opening a new one or adding files to the current workspace. ### What it does The `--reuse` flag finds an available local workspace window and replaces its workspace with the newly specified paths. This provides a third workspace opening mode alongside the existing `--add` and `--new` flags. ### Implementation Details - **CLI Flag**: Added `--reuse` (`-r`) flag with proper mutual exclusion with `--add` and `--new` - **Window Replacement**: Uses the existing `replace_window` option in `workspace::OpenOptions` - **Window Selection**: Reuses the first available local workspace window - **Fallback Behavior**: When no existing windows are found, creates a new window - **Test Coverage**: Added comprehensive test for the reuse functionality ### Behavior - `zed -r file.txt` - Replaces the workspace in an available window with `file.txt` - If no windows are open, creates a new window (same as default behavior) - Mutually exclusive with `-a/--add` and `-n/--new` flags - Works with multiple files and directories ### Files Changed - `crates/cli/src/cli.rs` - Added `reuse` field to `CliRequest::Open` - `crates/cli/src/main.rs` - Added CLI argument definition and parsing - `crates/zed/src/zed/open_listener.rs` - Implemented reuse logic and added tests - `crates/zed/src/zed/windows_only_instance.rs` - Updated for Windows compatibility ### Testing - ✅ Unit tests pass - ✅ Manual testing confirms expected behavior: - Works when no windows are open - Replaces workspace in existing window - Maintains compatibility with existing `-a` and `-n` flags - Proper help text display ## Manual testing #### In this first video we do a couple of tests: * **1**: What happens if we use the -r flag when there are no windows open? - works as expected. It opens the files in a new window. * **2**: Does it work as expected if there is already a window open. Does it overrides the workspace? - yes it does. When opening a different file it overrides the current window instead of creating a new one. * **3**: Does the -n flag still works as expected? - yes, it creates the project in a new window * **4**: What about the -a flag? - yes, on the last accessed page * **5**: we do the replace command. It overrides the first opened window, do we want this behavior? - It is good enough that it overrides one of the opened windows with the new project. It still makes the user automatically go to the window with the specified files * **6**: we use the -r command again replacing the workspace with a new one. - this indeed worked as expected https://github.com/user-attachments/assets/f1cd7f4b-f4af-4da2-a755-c0be7ce96c0d #### In here the we check how the --help flag now displays the new command.

Testing
You can test your changes to the cli crate by first building the main zed binary:
cargo build -p zed
And then building and running the cli crate with the following parameters:
cargo run -p cli -- --zed ./target/debug/zed.exe
