# Windows System Commands Plugin
|
|
|
|
As the name suggests, the Windows System Commands Plugin is used to directly run Windows system commands that have been entered by the user as a query. This is done by parsing the entry and validating the command, followed by executing it.
|
|
|
|
The user can change the behavior of the plugin (language, confirmation dialog, ...) with optional plugin settings.
|
|
|
|
|
|
|
|
Available commands:
|
|
* Shutdown
|
|
* Restart
|
|
* Sign Out
|
|
* Lock
|
|
* Sleep
|
|
* Hibernate
|
|
* Open / Empty Recycle Bin
|
|
* UEFI Firmware Settings (Only available on systems, that boot in UEFI mode.)
|
|
* IP / MAC / Address => Show informations about network connections.
|
|
|
|
## Optional plugin settings
|
|
|
|
* We have the following settings that the user can configure to change the behavior of the plugin:
|
|
|
|
| Key | Default value | Name/Description |
|
|
|--------------|-----------|------------|
|
|
| `ConfirmSystemCommands` | `false` | Show a dialog to confirm system commands |
|
|
| `LocalizeSystemCommands` | `true` | Use localized system commands instead of English ones |
|
|
| `ReduceNetworkResultScore` | `true` | Reduce the priority of 'IP' and 'MAC' results to improve the order in the global results |
|
|
|
|
* The optional plugin settings are implemented via the [`ISettingProvider`](/src/modules/launcher/Wox.Plugin/ISettingProvider.cs) interface from `Wox.Plugin` project. All available settings for the plugin are defined in the [`Main`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Main.cs) class of the plugin.
|
|
|
|
## Technical details
|
|
|
|
### [`Main`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Main.cs)
|
|
|
|
* Tries to parse the user input and returns a specific Windows system command by using a [`Result`](/src/modules/launcher/Wox.Plugin/Result.cs) list.
|
|
|
|
* While parsing, the plugin uses [`FuzzyMatch`](/src/modules/launcher/Wox.Infrastructure/StringMatcher.cs) to get characters matching a result in the list.
|
|
|
|
### [`Commands.cs`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Components/Commands.cs)
|
|
- The [`Commands`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Components/Commands.cs) class contains the definition of all available commands/results.
|
|
|
|
### [`ResultHelper.cs`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Components/ResultHelper.cs)
|
|
- The [`ResultHelper`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Components/ResultHelper.cs) class contains methods for working with the results and some of the result features (tool tip, copy to clipboard, execute command).
|
|
- **Recycle Bin command:** The context menu action to empty the Recycle Bin is executed as an async task to not block PowerToys Run. (While the task is running the static class variable `executingEmptyRecycleBinTask` is set to true, to block multiple executions at the same time)
|
|
|
|
### [`NetworkConnectionProperties.cs`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Components/NetworkConnectionProperties.cs)
|
|
- The [`NetworkConnectionProperties`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Components/NetworkConnectionProperties.cs) class contains methods to get the properties of a network interface/connection.
|
|
- An instance of this class collects/provides all required informations about one connection/adapter.
|
|
|
|
### [`SystemPluginContext.cs`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Components/SystemPluginContext.cs)
|
|
- An instance of the class [`SystemPluginContext`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Components/SystemPluginContext.cs) contains/defines the context data of a system plugin result. We select the context menu based on the defined properties.
|
|
- It is used for the `ContextData` property of the [`Wox.Plugin.Result`](/src/modules/launcher/Wox.Plugin/Result.cs).
|
|
|
|
|
|
### UEFI command
|
|
|
|
* The UEFI command is only available on systems, that boot in UEFI mode.
|
|
|
|
* This is validated by checking the result of the method [`GetSystemFirmwareType`](/src/modules/launcher/Wox.Plugin/Common/Win32/Win32Helpers.cs), which uses the native method [`GetFirmwareType`](/src/modules/launcher/Wox.Plugin/Common/Win32/NativeMethods.cs) in `kernel32.dll`.
|
|
|
|
## Search
|
|
|
|
### Score
|
|
|
|
* [`CalculateSearchScore`](/src/modules/launcher/Wox.Infrastructure/StringMatcher.cs) A match found near the beginning of a string is scored more than a match found near the end. A match is scored more if the characters in the patterns are closer to each other, while the score is lower if they are more spread out.
|
|
* For network results (IP address and MAC address) the score is reduced by 25 percent.
|
|
|
|
### Network results on global queries
|
|
- The network results (IP and MAC address) are only shown on global queries, if the search term starts with either IP, MAC or Address. (We compare case-insensitive.)
|
|
|
|
### Returning results
|
|
We return the results in two steps:
|
|
1. All results which we can create very fast like shutdown or logoff via [`Main.Query(Query query)`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Main.cs).
|
|
2. All results which need some time to create like the network results (IP, MAC) via [`Main.Query(Query query, bool delayedExecution)`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System/Main.cs).
|
|
|
|
## [Unit Tests](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System.UnitTests)
|
|
We have a [Unit Test project](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System.UnitTests) that executes various test to ensure that the plugin works as expected.
|
|
|
|
### [`ImageTests.cs`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System.UnitTests/ImageTests.cs)
|
|
- The [`ImageTests.cs`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System.UnitTests/ImageTests.cs) class contains tests to validate that each result shows the expected and correct image.
|
|
|
|
### [`QueryTests.cs`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System.UnitTests/QueryTests.cs)
|
|
- The [`QueryTests.cs`](/src/modules/launcher/Plugins/Microsoft.PowerToys.Run.Plugin.System.UnitTests/QueryTests.cs) class contains tests to validate that the user gets the correct results when searching.
