Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

jc: Converts the output of popular command-line tools to JSON
> In FreeBSD, this problem was solved with libxo[0]:
Libxo happens to be in the base system, but it is generally available:

* https://libxo.readthedocs.io/en/latest/

Or make it flexible:

* https://wiki.freebsd.org/LibXo
Want structure? Ask for JSON or XML and parse. Otherwise it's the regular text output.

Jc – JSONifies the output of many CLI tools
Can you trust it? Cli tool output is not exactly stable. I thought that's why libxo exists?

Curl gets a --json flag
Please consider https://github.com/Juniper/libxo or something even better than that.

You shouldn't parse the output of ls(1)
That would look a lot like FreeBSD. Many of the FreeBSD userland tools are set up to use the excellent libxo (https://github.com/Juniper/libxo) to allow the user's choice of how things are output.

Exploring Nushell, a Rust-powered, cross-platform shell
The first method is through downloading the pre-built binaries. With this method, you don't need to install anything other than Nushell's dependencies. Once you've downloaded the binaries, add them to your system's environment path to run it directly in your terminal.

PowerShell: The object-oriented shell you didn't know you needed
I rather nushell for this purpose, it's more fun to write and easier to read.

NuShell - Ceci n'est pas une |
These are just three small examples of what this shell written in Rust allows. The features are many and many more, but I'll leave it up to you to discover and enjoy them; I'm currently playing around with it and it's giving me a lot of satisfaction and immediacy, now it has a fixed place among the tools I use when working! The project is Open Source, so if you want to contribute, I invite you, as always, to do so, I leave you the link to the repo here!

Fish shell 3.7.0: last release branch before the full Rust rewrite
Any thoughts on fish as compared to nushell [0]? It's similar to PowerShell in its philosophy and is also written in Rust.

jc: Converts the output of popular command-line tools to JSON
> In PowerShell, structured output is the default and it seems to work very well.
PowerShell goes a step beyond JSON, by supporting actual mutable objects. So instead of just passing through structured data, you effectively pass around opaque objects that allow you to go back to earlier pipeline stages, and invoke methods, if I understand correctly: https://learn.microsoft.com/en-us/powershell/module/microsof....
I'm rather fond of wrappers like jc and libxo, and experimental shells like https://www.nushell.sh/. These still focus on passing data, not objects with executable methods. On some level, I find this comfortable: Structured data still feels pretty Unix-like, if that makes sense? If I want actual objects, then it's probably time to fire up Python or Ruby.
Knowing when to switch from a shell script to a full-fledged programming language is important, even if your shell is basically awesome and has good programming features.

jq 1.7 Released
Yeah agreed, especially now that PowerShell is available cross-platform.
Nushell[1] also seems like a promising alternative, but I haven’t had a chance to play with it yet.

The Case for Nushell
I also discovered an existing discussion[1] related to this topic which includes a link[2] to a "helper to call nushell nuon/json/yaml commands from bash/fish/zsh" and a comment[3] that the current nushell dev focus is "on getting the experience inside nushell right and [we] probably won't be able to dedicate design time to get the interface of native Nu commands with an outside POSIX shell right and stable.".
