Getting global config values?

[zmitchell]

I’m just starting to poke around gix so forgive me if this is clearly documented somewhere. How would you read global config values? I see that there’s some config-reading functionality for repos, but what if I want to know a global config value outside of the context of a repo?

For instance, my use case is making a tool to manage a worktrees workflow, and I want to know the default branch name so I can create a directory/worktree named after the default branch.

This should do the trick.

let repo = gix::open(repo_path)?;
repo.config_snapshot().string_by_key("init.defaultBranch")?;

[zmitchell]

Even if there’s no repo at repo_path? Like I said, I want to know what the global config is even when there’s not a repo yet.

Right, then the Source type can be used to get the path to the respective configuration file to open. Then there is from_globals() which is probably more in line with what you need as it incorporates all non-repo files.
