This may have been intentional, but submitting this in case it wasn't. Allows to have longer-running tasks, which is useful when testing what agent has done while replying to another task in the same or different project.

Summary of Changes

Hello @jutaz, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request resolves a bug where active terminal processes would terminate or close when a user switched between different tasks or projects. The changes ensure that terminal states are preserved and remain active, significantly enhancing the user experience for long-running operations. This is achieved by optimizing how inactive project views are rendered to maintain their state and by persisting the terminal's visibility settings using local storage.

Highlights

  • Prevent Terminal Closure on Task/Project Switch: The ProjectView component now uses CSS contentVisibility and zIndex properties to hide inactive project views instead of unmounting them. This ensures that any running terminal processes within these projects remain active and do not terminate when switching between tasks or projects.
  • Persist Terminal Visibility State: The terminalVisible state in TaskView has been updated to use useLocalStorage. This change makes the terminal's visibility persistent across sessions and unique to each specific task and project, so users don't lose their terminal state when navigating away.
  • Enhanced Test Coverage: New test cases have been added to ProjectView.test.tsx to verify the correct application of contentVisibility and zIndex styles for active/inactive projects, and to confirm that terminal processes are not inadvertently closed during project switches. TaskView.test.tsx also received new tests to ensure terminal visibility persistence and independent state management for different tasks.

Code Review

This pull request successfully addresses the bug of terminals closing when switching tasks. The implementation uses contentVisibility and zIndex to hide inactive project views, ensuring that components like terminals remain active. Additionally, the terminal's visibility state is now persisted per task using useLocalStorage, which is a great improvement for user experience. The new test cases in ProjectView.test.tsx adequately cover the styling and non-termination aspects. However, one test case in TaskView.test.tsx is incomplete and needs to be finished to fully validate the terminal visibility toggling and persistence.

it('toggles terminal visibility and updates localStorage correctly', () => {
render(<TaskView project={mockProject} task={mockTask} updateTask={mockUpdateTask} inputHistory={[]} />);

// Initially false
expect(localStorage.getItem(`terminal-visible-${mockProject.baseDir}-${mockTask.id}`)).toBeNull();

// Find the toggle button - it's in PromptField, which has toggleTerminal prop
// Since PromptField is mocked, I need to check if toggleTerminal is called
// But since it's mocked, perhaps I need to mock PromptField to expose the toggle
// For now, since the component has toggleTerminal, and it's passed to PromptField
// To test, I can assume the button is there, but since mocked, perhaps test the state change

// Since useLocalStorage is not mocked, and it uses localStorage, when setTerminalVisible is called, it should update localStorage
// But since the component is rendered, and toggle is not called yet, localStorage is not set
// When toggleTerminal is called, it calls setTerminalVisible(!terminalVisible)
// Since PromptField is mocked, I need to trigger the toggle somehow

// Perhaps I need to unmock PromptField or mock it to call toggleTerminal
// Let's modify the PromptField mock to have a button that calls toggleTerminal

// Update the PromptField mock
// In the existing mock, add toggleTerminal to the props
// The mock is: PromptField: ({ runPrompt, addFiles }: { runPrompt: (prompt: string) => void; addFiles: (files: string[], readOnly: boolean) => void }) => (
// Add toggleTerminal?: () => void

// Let's edit the mock
});

The test case it('toggles terminal visibility and updates localStorage correctly', () => { ... }); is incomplete. It contains comments indicating that the mock for PromptField needs to be adjusted to properly trigger and test the toggleTerminal functionality. Please complete this test to ensure that the terminal visibility toggling works as expected and correctly updates localStorage.

I don't think this change is needed. This is already done one level higher in Home component.

@jutaz
When switching between tasks, does the Terminal keep its internal state (previously ran output, etc.)?
