Julia Session Management

Manage multiple concurrent Julia REPL sessions. Each session has its own isolated worker process with separate state, packages, and project environment.

Arguments

• action - One of: create, switch, list, destroy
• name - Session name (required for create/switch/destroy)

Instructions

Parse the user's arguments:

User Input	Action	Name
create analysis	create	analysis
switch testing	switch	testing
list	list	(none)
destroy old-session	destroy	old-session

Call session with the appropriate action and name parameters.

When to Create Separate Sessions

• Development + Testing: One session for development work, another for running tests
• Multiple Projects: One session per project when working across repos
• Benchmarking: Isolate benchmark runs from development state
• Experimentation: Try something risky without affecting your main session

Session Lifecycle

1. Sessions start with no worker — workers spawn lazily on first eval
2. Each session gets its own Malt.jl worker process
3. Variables, packages, and project environment are fully isolated between sessions
4. Revise.jl is auto-loaded on each worker if available
5. The "default" session is auto-created if you use eval without creating a session first

Notes

• Session names should be short, descriptive identifiers (e.g., "dev", "test", "analysis")
• Use list to see all sessions with their worker status, project, and Revise availability
• The * marker in list output indicates the current session
• Destroying a session kills its worker process immediately
• If you destroy the current session, another session becomes current automatically
