# Logging
|
|
|
|
Logging plays an important part in determining bugs in our code. It provides context for the developers about where and when errors occur.
|
|
|
|
## Where are the logs saved
|
|
|
|
* Most of the logs are saved under `%LOCALAPPDATA%/Microsoft/PowerToys`.
|
|
* For low-privilege processes (like preview handlers) the logs are saved under `%USERPROFILE%/AppData/LocalLow/Microsoft/PowerToys`.
|
|
|
|
Logs are normally in a subfolder with the module name as title.
|
|
|
|
The [BugReportTool](/tools/BugReportTool) will take logs from both locations when executed.
|
|
|
|
## Using a logger in a project
|
|
|
|
### Spdlog
|
|
|
|
In C++ projects we use the awesome [spdlog](https://github.com/gabime/spdlog) library for logging as a git submodule under the `deps` directory. To use it in your project, just include [spdlog.props](/deps/spdlog.props) in a .vcxproj like this:
|
|
|
|
```xml
|
|
<Import Project="..\..\..\deps\spdlog.props" />
|
|
```
|
|
It'll add the required include dirs and link the library binary itself.
|
|
|
|
### PowerToys Logger in ManagedCommon
|
|
|
|
For C# projects there is a static logger class in Managed Common called `Logger`.
|
|
|
|
To use it, add a project reference to `ManagedCommon` and add the following line of code to all the files using the logger:
|
|
|
|
```Csharp
|
|
using ManagedCommon;
|
|
```
|
|
|
|
In the `Main` function (or a function with a similar meaning (like `App` in a `App.xaml.cs` file)) you have to call `InitializeLogger` and specify the location where the logs will be saved (always use a path scheme similar to this example):
|
|
|
|
```Csharp
|
|
Logger.InitializeLogger("\\FancyZones\\Editor\\Logs");
|
|
```
|
|
|
|
For a low-privilege process you have to set the optional second parameter to `true`:
|
|
|
|
```Csharp
|
|
Logger.InitializeLogger("\\FileExplorer\\Monaco\\Logs", true);
|
|
```
|
|
|
|
The `Logger` class contains the following logging functions:
|
|
|
|
```Csharp
|
|
// Logs an error that the utility encountered
|
|
Logger.LogError(string message);
|
|
Logger.LogError(string message, Exception ex);
|
|
// Logs an error that isn't that grave
|
|
Logger.LogWarning(string message);
|
|
// Logs what the app is doing at the moment
|
|
Logger.LogInfo(string message);
|
|
// Like LogInfo just with infos important for debugging
|
|
Logger.LogDebug(string message);
|
|
// Logs the current state of the utility.
|
|
Logger.LogTrace();
|
|
```
