feat: shallow clone by hash

[lostl1ght]

Closes #155.

Also, right after building I get an error:

thread 'main' panicked at 'Failed to spawn child process: Os { code: 2, kind: NotFound, message: "No such file or directory" }', src/main.rs:84:14
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

RUST_BACKTRACE=1 does not help.

But switching to another version (e.g. nightly) and back helps.

is that only happening when you are building(as in not executing any command/running neovim)

I'm sorry I was not clear enough. This happens when I'm trying to execute neovim.

Oh fair enough, ill have to check this issue.

@lostl1ght any steps to take in order to recreate this issue?

[lostl1ght]

Just these:

cargo r -- use 9cadbf1d36b63f53f0de48c8c5ff6c752ff05d70 # any hash really

$HOME/.local/share/bob/nvim-bin/nvim

Result: panic.

[lostl1ght]

The problem is in the file used and the name of a directory to a version itself. The hash in the name of a directory is shortened and in the file used is not. I can't quite figure out when that happens.

[lostl1ght]

I think I figured it out. Now everything works.

[MordechaiHadad]

works nicely, two things that could be changed:

• do a check in the build function that if it's not the full hash abort the operation and tell them to provide the full hash.
• (optional, i can do later) disable the stdout for git init

[lostl1ght]

disable the stdout for git init

Done. I've also disabled the stdout for remote get-url and checkout as they do not provide anything meaningful:

• remote get-url prints the url of the remote if available and nothing otherwise
• checkout just complains that HEAD is detached

@lostl1ght I will try creating a new release tomorrow. thanks for the PR!
