cargo info implementation (similar to npm show/info cmd)

[hltdev8642]

Describe the problem you are trying to solve

So I frequently use with ruby/npm/apt the show / info commands to get more package information (link to git, homepage, keywords, etc), but as far as I know this isn't possible with cargo. I thought it would be really useful to have the ability to use something along the lines of: cargo show [pkgname] to get some basic info about a package.

Describe the solution you'd like

I created a script that implements the crates.io api, it is just preliminary and the only requirement is the package jq . I included the version I made which has a colored output, although this could easily be removed/disabled by replacing the color-echo cmds simply with echo.

That script is here, id be curious what people think.

To run:

• Install dependencies (not much, could probably be eliminated altogether using awk anyways)

apt install jq

• Either save somewhere in $PATH, or just run locally via ./cargo-show. (obviously chmod +x it as well)

To search:
cargo-show [packagename]

Looks like this:

It looks like this is a duplicate of #948, closing in favor of that
