Nushell 0.12.0 Release Notes: Automatic cd, Type Inference, and Jupyter Notebook Support

--- title: Nushell 0.12.0 author: The Nu Authors author_site: https://twitter.com/nu_shell author_image: https://www.nushell.sh/blog/images/nu_logo.png excerpt: We're excited to release version 0.12.0 of Nu! --- # Nushell 0.12.0 Nushell, or Nu for short, is a new shell that takes a modern, structured approach to your commandline. It works seamlessly with the data from your filesystem, operating system, and a growing number of file formats to make it easy to build powerful commandline pipelines. We're excited to release version 0.12.0 of Nu! # Where to get it Nu 0.12.0 is available as [pre-built binaries](https://github.com/nushell/nushell/releases/tag/0.12.0) or from [crates.io](https://crates.io/crates/nu). If you have Rust installed you can install it using `cargo install nu`. If you want more goodies, you can install `cargo install nu --features=stable`. As part of this release, we also publish a set of plugins you can install and use with Nu. To install, use `cargo install nu_plugin_<plugin name>`. # What's new ## Automatic `cd` (sophiajt) ``` nushell on 📙 master is 📦 v0.12.0 via 🦀 v1.42.0 ❯ docs nushell/docs on 📙 master ❯ .. nushell on 📙 master is 📦 v0.12.0 via 🦀 v1.42.0 ``` Fish and Windows users rejoice, you can now `cd` to a directory or drive by typing its name in the shell. This also allows Windows users to change drives by giving just the drive name. Now, when you use the drive letter, we'll switch drives and return you to your previous working directory on that drive (eg `D:` will change to the D: drive and `cd` to the path you had been at previously). ## Type inference (andrasio) ``` ❯ open tests/fixtures/formats//caco3_plastics.csv | get cif_per_net_weight ───┬───────── # │ <value> ───┼───────── 0 │ 0.2300 1 │ 0.3100 2 │ 0.1400 3 │ 0.2300 4 │ 0.2100 5 │ 0.2800 6 │ 0.3000 7 │ 0.2500 8 │ 0.2800 ───┴───────── nushell on 📙 master is 📦 v0.12.0 via 🦀 v1.42.0 ❯ open tests/fixtures/formats//caco3_plastics.csv | get cif_per_net_weight | sum 2.23 ``` We've been hard at work at improving how we read in unstructured data. In this release, you'll see the beginning of type inference as data is read in. In the above example, you can see how we now autodetect decimal numbers and then can later sum them together. ## Jupyter notebook support (sophiajt)

Nushell 0.12.0 is released with new features. It includes automatic 'cd' into directories by just typing the directory name, type inference to better handle unstructured data, and support for Jupyter notebooks, allowing users to run Nushell commands directly within Jupyter environments.
