feat: split to create a library

[jayvdb]

Not the cleanest split; happy to revise.
And also happy for this to not be published until it goes through a few more revisions to clean it up to produce a sensible API. (e.g. MainError probably doesnt belong in the lib)

@KSXGitHub , do you feel this might be possible ?

[jayvdb]

fwiw, I have developed a few other pnpm invocation wrappers which I would like to find a open source home for. See simonbuchan/pnpm-extra#2 for one of them.

Technically possible. I have created plenty of Rust projects (not related to pnpm) that is both a library crate and a binary crate. All you have to do is to define both [lib] and [[bin]] in Cargo.toml.

I believe this isnt necessary unless there are attributes needed to describe them.

i.e.
having both src/lib.rs and src/main.rs is sufficient...?

cargo run and cargo build do the appropriate things afaics

Why is a lib needed? Maintaining a library along with the CLI creates more work for us.

See earlier comment #62 (comment)

I would like to use pn in my Rust project.

Thanks for approving.
I should add that I am happy to use git = ".." in my deps, so no need to do a release, and also I am expecting that the lib is very unstable.

It would be a good idea to follow this up with adding a header to the lib.rs to indicate that it is unstable, e.g. https://github.com/simonbuchan/pnpm-extra/blob/main/src/lib.rs , and maybe even hide it from the rust docs , e.g. https://github.com/Electron100/butane/blob/master/butane_cli/src/lib.rs
