This week in Nushell #255

Nushell

• devyn landed a massive Internal Representation (IR) compiler and evaluator PR 🎉🎉🎉 and then did lots of mostly related work: fixed the file count in the Debug implementation of IrBlock, fixed the order of I/O types in take until, included the actual output type in an OutputMismatch error, made the store-env IR instruction also update the config, added IR support to the debugger, included more argument types to view ir, fixed the signature of view ir, set the capacity of the Vec used in gather_captures() to the expected number of captures, avoided cloning in Signature::get_positional(), made pipe redirections consistent and added err>| and similar forms, used Arc for environment variables on the stack, updated the config directly at assignment, and made into bits produce a bitstring stream.
• ysthakur prevented the touch command from being added twice to the default context.
• fdncred tweaked parse usage and examples for better clarity and did a quick fix up for IR PR as referenced.

• zhiburt fixed unused space issues when truncation is used and header on border is configured and fixed the kv table width issue with header_on_border configuration.
• 132ikl fixed the main binary being rebuilt when nothing has changed.
