Darren Schroeder 761946c522 add the ability to combine columns with `detect columns` (#9511 ) # Description This PR adds the ability to manually combine columns in the `detect columns` command. This is useful when items are close together but want them to be in one column. For example, if you want to parse the output of bash's `ls` command, the output passed into `detect columns` would look similar to this. ``` ❯ ^ls -lh total 242K -rw-r--r-- 1 dschroeder 197121 3.5K Mar 30 10:10 CODE_OF_CONDUCT.md -rw-r--r-- 1 dschroeder 197121 11K Jun 21 14:16 CONTRIBUTING.md -rw-r--r-- 1 dschroeder 197121 153K Jun 21 14:16 Cargo.lock -rw-r--r-- 1 dschroeder 197121 5.7K Jun 21 08:47 Cargo.toml -rw-r--r-- 1 dschroeder 197121 371 Mar 30 10:10 Cross.toml -rw-r--r-- 1 dschroeder 197121 1.1K Apr 3 08:37 LICENSE -rw-r--r-- 1 dschroeder 197121 13K Jun 21 14:16 README.md drwxr-xr-x 1 dschroeder 197121 0 May 24 08:06 assets drwxr-xr-x 1 dschroeder 197121 0 Jun 21 14:16 benches -rw-r--r-- 1 dschroeder 197121 310 Mar 30 10:10 codecov.yml drwxr-xr-x 1 dschroeder 197121 0 Jun 1 15:30 crates drwxr-xr-x 1 dschroeder 197121 0 May 4 07:55 dict drwxr-xr-x 1 dschroeder 197121 0 Mar 30 10:10 docker -rw-r--r-- 1 dschroeder 197121 1.1K Jun 12 07:03 rust-toolchain.toml drwxr-xr-x 1 dschroeder 197121 0 May 26 07:11 scripts drwxr-xr-x 1 dschroeder 197121 0 Jun 15 07:14 src drwxr-xr-x 1 dschroeder 197121 0 Jun 21 09:48 target drwxr-xr-x 1 dschroeder 197121 0 Jun 21 12:30 tests -rw-r--r-- 1 dschroeder 197121 16K Jun 21 14:16 toolkit.nu drwxr-xr-x 1 dschroeder 197121 0 Jun 1 15:30 wix ``` Running it through `detect columns` is helpful but notice how the Month, Day, and Time are in their own columns. ``` ❯ ^ls -lh \| detect columns --no-headers --skip 1 ╭────┬────────────┬─────────┬────────────┬─────────┬─────────┬─────────┬─────────┬─────────┬─────────────────────╮ │ #

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.
