PairIt

PairIt is an extension to facilitate pair and mob programming sessions over Live Share.

In its current version, it simply assigns and dynamically updates the roles of users in a mob programming session.

Roles

There are three distinct roles:

• Driver. Responsible for actually writing code.
• Navigator. Makes decisions about what to do and directs the driver.
• Mob. Passive observer.

There should be one driver, one navigator, and the remainder of the participants are part of the mob.

Role Updates

There are three situations that cause a participant's role to change:

• On schedule. Every four minutes roles are rotated.
• Leave. If the driver or the navigator leaves the session, another participant will assume their role.
• Join. When someone first joins a session, they are assigned a role.

Extension Design

Like most Live Share extensions, the host is the source of truth. The host maintains a list of all participants in the session and their roles and keeps track of time. Anytime a participant needs to be assigned a new role (see Role Updates), the host will send a notification to all guests. This notification contains a map from client id to role. Guests will look up their role from this map and update their role. Anytime your role is changed, you'll receive a notification. Your role is displayed in the status bar at all times.
