## What
Display the currently active pulumi logged-in user, url and stack.
:::caution
This requires a pulumi binary in your PATH and will only show in directories that contain a `Pulumi.yaml` file.
:::
## Sample Configuration
import Config from "@site/src/components/Config.js";
<Config
data={{
type: "pulumi",
style: "diamond",
powerline_symbol: "\uE0CF",
foreground: "#ffffff",
background: "#662d91",
template:
"{{ .Stack }}{{if .User }} :: {{ .User }}@{{ end }}{{ if .URL }}{{ .URL }}{{ end }}",
}}
/>
## Properties
| Name | Type | Default | Description |
| ------------- | --------- | ------- | ---------------------------------------------------------------------------------- |
| `fetch_stack` | `boolean` | `false` | fetch the current stack name |
| `fetch_about` | `boolean` | `false` | fetch the URL and user for the current stask. Requires `fetch_stack` set to `true` |
## Template ([info][templates])
:::note default template
```template
{{ .Stack }}{{if .User }} :: {{ .User }}@{{ end }}{{ if .URL }}{{ .URL }}{{ end }}
```
:::
### Properties
| Name | Type | Description |
| -------- | -------- | -------------------------------------------------- |
| `.Stack` | `string` | the current stack name |
| `.User` | `string` | is the current logged in user |
| `.Url` | `string` | the URL of the state where pulumi stores resources |
