SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Detects the active version control system (jj or git) for the current project so you can run the correct CLI commands.

Core Features & Use Cases

  • Detects between jj and git for colocated repositories.
  • Guides users to run the appropriate VCS commands to avoid errors.
  • Works by probing repository roots with jj root and git rev-parse --show-toplevel to determine the VCS.

Quick Start

Run the detection command before performing any VCS operation to determine the appropriate CLI.

FAQPage Schema
How do I detect whether a colocated repository uses jj or git?▼

To detect the active VCS in a colocated repository, probe the repository roots by attempting `jj root` first, then `git rev-parse --show-toplevel`. This detection mechanism ensures you select the appropriate CLI before executing any version control commands.

Why do I get errors running git commands in a jujutsu colocated repo?▼

Errors occur in a colocated repo when using the wrong VCS CLI. Detecting the active version control system first prevents this by probing `jj root` before `git rev-parse`, guiding you to run the appropriate VCS commands and avoid mismatches.

What is the best way to check the VCS root before running version control commands?▼

The best way to check the VCS root is attempting `jj root` first, then `git rev-parse --show-toplevel`, falling back to 'none' if neither succeeds. This probing mechanism determines the correct CLI for your current project.

Can I use this VCS detection for projects that only use git?▼

Yes, you can use this detection for projects that only use git. The mechanism attempts `jj root` first, then falls back to `git rev-parse --show-toplevel`, correctly identifying git as the active version control system when no jujutsu root exists.

Does the detection work when neither jj nor git is initialized in the directory?▼

The detection handles directories without an active VCS by falling back to 'none' when both `jj root` and `git rev-parse --show-toplevel` fail. This ensures you know no version control system is present before attempting commands.
