Local sources for dependencies

[ALameLlama]

I was wonder if it's currently possible to install local packages e.g
lib-1
lib-2

lib-2 needs to install lib-1.

I've tried a few different things by setting the source.url and generating a rockspec and then trying to install the rockspec but I can't get this working.

Is there a better way to handle this? I want to be able to install packages from a local source so I can test changes before pushing anything.

Thanks

Hey 👋

Using local packages as dependencies isn't currently supported.
I haven't tried it myself, but you could try using git dependencies, where the git field is a local git URL (e.g. git@localhost:/path/to/local/git/repo).
It might have trouble with SSH authentication though.

You could also set LUA_PATH and LUA_CPATH to include your local project.

You get that with both:

git = "git+ssh://git.llamacorp.au/umbra-framework/contracts.git"

and:

# Without the .git suffix
git = "git+ssh://git.llamacorp.au/umbra-framework/contracts"

?

[ALameLlama]

Correct, same thing with both of them.
just for reference this is what I have and was just commenting/uncommenting them

[dependencies.shade-contracts]
git = "https://git.llamacorp.au/umbra-framework/contracts.git"
# git = "git+ssh://git.llamacorp.au/umbra-framework/contracts.git"
# git = "git+ssh://git.llamacorp.au/umbra-framework/contracts"
version = "master"

Hmm, I tried adding a test case (to the lux-lib::lua_rockspec::rock_source::parse_source_url() test) and it passed.
InvalidSpec seems to be an error from the git2 crate, so this is likely an issue with libgit2 or the rust wrapper.

[ALameLlama]

after much digging, it looks like the issue isn't with git2 or libgit2 but the git_url_parse crate.

lux/lux-lib/src/git/url.rs

Line 49 in 7269299

url_str: url.to_string(),

    let test_urls = vec![
        "git+ssh://git.llamacorp.au/umbra-framework/contracts.git",
        "git+ssh://git.llamacorp.au/umbra-framework/contracts",
    ];
    
    for original_url in test_urls {
        let parsed = GitUrl::parse(original_url).unwrap();
        let transformed_url = parsed.to_string();
        
        println!("  Original:     {}", original_url);
        println!("  Transformed:  {}", transformed_url);
	}

  Original:     ssh://git.llamacorp.au/umbra-framework/contracts.git
  Transformed:  ssh://git.llamacorp.au:umbra-framework/contracts.git

it's changed the / after the hostname to :

I'll raise an issue upstream shortly

Sorry for hijacking this thread but I've realized it's trying to parse a port and getting confused so changing it to git+ssh://git.llamacorp.au:22/umbra-framework/contracts.git "works" but now it gets an auth error so my guess is there is something else with git2-rs or libgit2 where it's not able to use the ssh agent.

this might be a pebkac issue with my nixos setup

I've created a PR to lux to fix the auth issue
