Add add/import subcommand

[AstraLuma]

Add a command to quickly & easily import a file into an emanate repo. (Avoiding the dance.)

@astronouth7303 I really like this idea, but there's some small details to work out.

First, is this (approximately) the dance you're referring to?

$ mv ~/some-file ~/dotfiles
$ cd ~/dotfiles
~/dotfiles$ emanate

Second, how clever should it try to be?

I think a crude proof-of-concept could be to just have a command do something along the lines of this in emanate.cli:

# NOTE: This code is untested and incomplete, but I think is in the right ballpark for a proof-of-concept.

# In `emanate.Emanate`:
def add(file): # Can't be called `import` to avoid angering the snek, so I guess we're going with `add`?
    file_path = Path(file).expanduser().absolute() # or something like that
    dest_path = str(file_path).sub(self.config.source, self.dest) # possibly?
    file_path.rename(dest_path) # rename won't clobber existing files afaik.

Then, in emanate.cli, basically map emanate add <file> => Emanate(...).add("<file>")

Something to that effect? Assuming you have some knowledge about where the source was

[AstraLuma]

Oh, and directories are Fun

[duckinator]

When you run emanate, it has a --source <source directory> flag for all subcommands. If you don't specify it, it defaults to the cwd.

So with something like that code above, you could just do emanate --source /path/to/srcdir add <file>.

But yeah, directories would be... interesting. EDIT: actually I think the idea above should handle directories fine.

I think we should (try to?) ensure the operation is atomic (i.e. either everything got moved and symlinked to the Emanate repo, or nothing changed and we returned with an error)

[duckinator]

I agree. I'm pretty hesitant to add this if it's not atomic, or damn close to it.
