# Description Close: #9673 Close: #8277 Close: #10944 This pr introduces the following syntax: 1. `e>|`, pipe stderr to next command. Example: `$env.FOO=bar nu --testbin echo_env_stderr FOO e>| str length` 2. `o+e>|` and `e+o>|`, pipe both stdout and stderr to next command, example: `$env.FOO=bar nu --testbin echo_env_mixed out-err FOO FOO e+o>| str length` Note: it only works for external commands. ~There is no different for internal commands, that is, the following three commands do the same things:~ Edit: it raises errors if we want to pipes for internal commands ``` ❯ ls e>| str length Error: × `e>|` only works with external streams ╭─[entry #1:1:1] 1 │ ls e>| str length · ─┬─ · ╰── `e>|` only works on external streams ╰──── ❯ ls e+o>| str length Error: × `o+e>|` only works with external streams ╭─[entry #2:1:1] 1 │ ls e+o>| str length · ──┬── · ╰── `o+e>|` only works on external streams ╰──── ``` This can help us to avoid some strange issues like the following: `$env.FOO=bar (nu --testbin echo_env_stderr FOO) e>| str length` Which is hard to understand and hard to explain to users. # User-Facing Changes Nan # Tests + Formatting To be done # After Submitting Maybe update documentation about these syntax. |

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.
