FAQPage Schema

How do I manage isolated development sessions using git worktrees and tmux?▼

You can manage isolated development sessions by running the psm alias, which automates git worktree and tmux session creation to provide consistent, repeatable workspace environments for parallel projects.

What is the best way to spin up a repeatable project workspace across different machines?▼

The best way to reproduce a workspace is using the psm alias to interface with project-session-manager, which handles safe session creation and teardown while supporting template usage for consistent environments.

Does psm require a separate project-session-manager installation to handle tmux sessions?▼

Yes, psm functions as a concise alias and requires integration with the underlying project-session-manager functionality to execute the actual worktree and tmux session management operations.

Can I switch between multiple parallel project tasks quickly without losing my environment setup?▼

Yes, you can seamlessly switch between tasks using the psm alias, which provides quick access to project-session-manager for handling worktree and tmux session state without losing your environment setup.

How do I safely tear down a tmux session and git worktree after finishing a task?▼

You can safely tear down a session by running psm with the appropriate arguments, triggering the project-session-manager's safe teardown functionality to clean up the tmux session and git worktree environment.
