# Description Adds support for running plugins using local socket communication instead of stdio. This will be an optional thing that not all plugins have to support. This frees up stdio for use to make plugins that use stdio to create terminal UIs, cc @amtoine, @fdncred. This uses the [`interprocess`](https://crates.io/crates/interprocess) crate (298 stars, MIT license, actively maintained), which seems to be the best option for cross-platform local socket support in Rust. On Windows, a local socket name is provided. On Unixes, it's a path. The socket name is kept to a relatively small size because some operating systems have pretty strict limits on the whole path (~100 chars), so on macOS for example we prefer `/tmp/nu.{pid}.{hash64}.sock` where the hash includes the plugin filename and timestamp to be unique enough. This also adds an API for moving plugins in and out of the foreground group, which is relevant for Unixes where direct terminal control depends on that. TODO: - [x] Generate local socket path according to OS conventions - [x] Add support for passing `--local-socket` to the plugin executable instead of `--stdio`, and communicating over that instead - [x] Test plugins that were broken, including [amtoine/nu_plugin_explore](https://github.com/amtoine/nu_plugin_explore) - [x] Automatically upgrade to using local sockets when supported, falling back if it doesn't work, transparently to the user without any visible error messages - Added protocol feature: `LocalSocket` - [x] Reset preferred mode to `None` on `register` - [x] Allow plugins to detect whether they're running on a local socket and can use stdio freely, so that TUI plugins can just produce an error message otherwise - Implemented via `EngineInterface::is_using_stdio()` - [x] Clean up foreground state when plugin command exits on the engine side too, not just whole plugin - [x] Make sure tests for failure cases work as intended - `nu_plugin_stress_internals` added # User-Facing Changes - TUI plugins work - Non-Rust plugins could optionally choose to use this - This might behave differently, so will need to test it carefully across different operating systems # Tests + Formatting - 🟢 `toolkit fmt` - 🟢 `toolkit clippy` - 🟢 `toolkit test` - 🟢 `toolkit test stdlib` # After Submitting - [ ] Document local socket option in plugin contrib docs - [ ] Document how to do a terminal UI plugin in plugin contrib docs - [ ] Document: `EnterForeground` engine call - [ ] Document: `LeaveForeground` engine call - [ ] Document: `LocalSocket` protocol feature |

Nushell core libraries and plugins
These sub-crates form both the foundation for Nu and a set of plugins which extend Nu with additional functionality.
Foundational libraries are split into two kinds of crates:
- Core crates - those crates that work together to build the Nushell language engine
- Support crates - a set of crates that support the engine with additional features like JSON support, ANSI support, and more.
Plugins are likewise also split into two types:
- Core plugins - plugins that provide part of the default experience of Nu, including access to the system properties, processes, and web-connectivity features.
- Extra plugins - these plugins run a wide range of different capabilities like working with different file types, charting, viewing binary data, and more.
