```
static async fromEnv(
  environment: Readonly<
    Record<string, string | undefined>
  > = process.env,
): Promise<Session>
```

Resolve the session this process is running inside.

The pane is authoritative: `$TMUX`'s exported session id goes stale when a
pane is moved, so the session is looked up through `$TMUX_PANE` instead.

## Examples

```ts
const current = await Session.fromEnv();
current.name;
```

## Parameters

- `environment` (`Readonly<Record<string, string | undefined>>`)
  Default: `process.env`.
