# Description Try to fixes https://github.com/nushell/nushell/issues/15326 in another way. The main point of this change is to avoid duplicate `write` and `close` a redirected file. So during compile, if compiler know current element is a sub-expression(defined by private `is_subexpression` function), it will no longer invoke `finish_redirection`. In this way, we can avoid duplicate `finish_redirection`. # User-Facing Changes `(^echo aa) o> /tmp/aaa` will no longer raise an error. Here is the IR after the pr: ``` # 3 registers, 12 instructions, 11 bytes of data # 1 file used for redirection 0: load-literal %1, string("aaa") 1: open-file file(0), %1, append = false 2: load-literal %1, glob-pattern("echo", no_expand = false) 3: load-literal %2, glob-pattern("true", no_expand = false) 4: push-positional %1 5: push-positional %2 6: redirect-out file(0) 7: redirect-err caller 8: call decl 135 "run-external", %0 9: write-file file(0), %0 10: close-file file(0) 11: return %0 ``` # Tests + Formatting Added 3 tests. # After Submitting Maybe need to update doc https://github.com/nushell/nushell.github.io/pull/1876 --------- Co-authored-by: Stefan Holderbach <sholderbach@users.noreply.github.com>
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.
