An example plugin for nushell to compute length of Strings

Warning
because all the dependencies for this plugin are not on crates.io, but rather only in the source of nushell, the path to all these dependencies, i.e. nu-plugin and nu-protocol are hardcoded to the nushell source on my machine.

even though the paths do not mention amtoine, they still are unique to my system...

to correctly install these dependencies, which btw are not present at all in the Cargo.toml to avoid any issues, one can (and probably should) run the following

> git clone https://github.com/nushell/nushell /path/to/nushell/

or choose another way to get the source code of nushell somewhere locally 😋

then

> use toolkit.nu
> toolkit setup /path/to/nushell/

and voila

Note
check git diff Cargo.toml to see the change 😉

• build and install the binary with

cargo install --path .

• register the plugin in nushell with

register /path/to/cargo/bin/nu_plugin_len

Note
for instance, i use ~/.local/share/cargo/bin/nu_plugin_len in the register above because my CARGO_HOME is set to ($env.XDG_DATA_HOME | path join "cargo"), i.e. ~/.local/share/cargo, in my env.nu

> "this is an example string" | len
25

one can have a look at the documentation of the crate by going to docs/
