This extension allows you to set your Visual Studio text cursor to the source code location currently viewed in Sourcetrail. If the viewed file is not open in Visual Studio, the extension will open and display it automatically.
Whenever you read some source code inside Visual Studio that you actually want to explore in Sourcetrail you can use this extension to activate the right-clicked symbol in Sourcetrail.
As a Clang based tool Sourcetrail supports the JSON Compilation Database format for simplified project setup. This extension enables you to generate a JSON Compilation Database from your Visual Studio projects and solutions.
The great news is: This format is independent from the Sourcetrail tool, so you can also use the generated Compilation Database to run other Clang based tools.
Use Visual Studio to open the SourcetrailExtension.sln and build the project called SourcetrailExtension.
Hint: If the build fails with an error that reads The "GetDeploymentPathFromVsixManifest" task failed unexpectedly. try to run the Reset the Visual Studio 2017 Experimental Instance command first.
The SourcetrailExtensionTests project contains both, unit tests and integration tests. When running an integration test it will automatically fire up a new instance of Visual Studio (called Experimental Instance) and simulate calls to the extension inside this instance. To make this work you need to point Visual Studio the the appropriate .testsettings file:
- From the menu bar choose
Test->Test Settings->Select Test Settings Fileand pick theIntegrationTests.testsettingsfile located at the root of this repository.
We really appreciate every possible kind of contributions. Pull-requests are greatly appreciated. If you want to submit one, please try to keep it as small as possible, so that we don't have to consider too many independent changes in the reviews. Better issue many small pull requests than one big one. That would let us pull smaller changes more quickly.
Thanks to Dakota Hawkins for contributions.
The SourcetrailExtension solution contains several different projects. This section should explain their purpose.
This project build the extension and contains the source code for all the main functionality.
This project contains all the unit tests and integration tests for the SourcetrailExtension project
This project contains some utility functionality (like the logging implementation) used by both, the SourcetrailExtension project and the SourcetrailExtensionTests project.
Ok, now things are getting interesting. While extracting all the required information for generating a Clang Compilation Database the Sourcetrail Extension uses the Microsoft.VisualStudio.VCProjectEngine assembly. Everything would be fine if we'd just build the extension for one single version of Visual Studio. But we are not.
According to this question on stackoverflow the classes of the Microsoft.VisualStudio.VCProjectEngine assembly have different GUIDs for each version released (e.g. 11, 12, 14, 15). So if we would build the extension referencing to VCProjectEngine version 15 (which is VS 2017) and install the extension in another version of VS (e.g. VS 2015) every cast to VCProjectEngine types (e.g. VCProject) would fail. Internally VS 2015 would have a VCProject of version 14 but our code tries to cast it to a VCProject of version 15 and fails.
In order to build just one extension that supports all versions of Visual Studio we are using wrappers for all VCProjectEngine types that we are interested in. Each kind of wrapper (e.g. the VCProjectWrapper) has an interface that offers all methods required in the context of this extension. Each interface has several implementations (one for each VS version). When a wrapped object instance is needed during runtime, a factory class that knows all available wrappers tries to instantiate each of them and returns the wrapper object that has been instantiated successfully (the one where the cast to the wrapped type succeeded).
This project contains the interface classes for the VCProjectEngine wrappers. This way other projects may use a wrapper without knowing exactly which version of the wrapper is used.
The projects for the actual wrappers all reference the same source files, so we have as little code duplication as possible. We require different projects for the individual wrappers because each wrapper's project references another version of the Microsoft.VisualStudio.VCProjectEngine assembly.
