The PowerShell Explorer allows you to view the AST, Modules and Providers in your PowerShell Environment.
You can explore the AST of the current PowerShell file by using the AST node in the PowerShell Explorer. Open a PS1 or PSM1 file and click the refresh button. The AST node will show which file the AST is currently showing. You can then click the nodes within the AST. Click the Select AST button to highlight the text in the editor that relates to that AST node.
If you want to clear the AST node selection, click the Clear Selection button.
The Module Explorer node provides the ability to view modules within your PowerShell environment. It will list all the modules and their versions directly in the tree view. If there is an updated version of a module, the update icon will be available and a description on the node will state the updated version that is available on the gallery. You can click the update button to update that module.
You can use the PowerShell Provider Explorer in the PowerShell Explorer window to traverse providers in your environment.
The Variable Explorer allows you to see a variables defined in your session without being in the debugger. You can expand and view their properties. Clicking the refresh button will refresh the variable list.
