This project attempts to create Sourcetrail-Databases from C# source code.
It is an offspring to my first project in the area of code-analysis, SourcetrailDotnetIndexer.

It uses the Roslyn compiler to parse the source and gather symbol-information.
It uses SourcetrailDB for writing the Sourcetrail-database.
For convenience, the native DLL for SourcetrailDB is already included, so you don't have to build it yourself.
Note, the native DLL is a x64 DLL so in your project settings, you have to specify x64 as the target platform as well.

---

Note, this project is in a very early and experimental state.
It probably contains bugs, so please be aware.

Contributors welcome !

As i'm only able to work on this project in my spare time, anyone who is able to contribute is welcome to do so !
If you have already worked with Roslyn, please check out the code and report any bugs you find or tell me how this tool can be made more efficient.

Building

Open the .sln in VisualStudio and build.
Make sure, you set the target-platform to x64 ! (because of the native SourcetrailDB.dll)

Usage

The following command-line arguments are supported:

• -i Input-File/Path
  Specifies the full path of a file or a folder to index
  If the argument refers to a folder, all *.cs-files in this folder and all sub-folders will be included
  may be specified multiple times
• -o OutputFilename
  Full path and filename of the generated Sourcetrail-database
• -r AssemblyPathOrFileName
  Specifies the path to a reference-assembly (used for type-resolution)
  If the argument refers to a folder, all assemblies in this folder will be referenced
  may be specified multiple times
• -fp Framework-Path
  Specifies the path to the .net-framework, your application is based on
  By default, the indexer attempts to use the .net5 assemblies
• -ox (OmitExternals)
  Specifies, that types from referenced assemblies should be omitted from the generated database

Examples:

• Creating a database for the indexer itself
  Assuming, the sources are stored in C:\code\SourcetrailCSharpIndexer\SourcetrailCSharpIndexer
  The indexer is run from the output-folder (e.g. \bin\Debug\net5.0)

  SourcetrailCSharpIndexer -i C:\code\SourcetrailCSharpIndexer\SourcetrailCSharpIndexer -o CSharpIndexer.srctrldb -ox

  This generates the files CSharpIndexer.srctrldb and CSharpIndexer.srctrlprj in the current directory.
  The file CSharpIndexer.srctrlprj is the one you open in Sourcetrail (via the Open Project command)

  If you open the database in Sourcetrail, you will notice that there are several errors reported in the database.
  This is because we did not reference the assemblies, that are required to actually compile and build the project.
  To add these assemblies, we build the project once in VisualStudio and then reference the assemblies from the output-folder.

• Extending the first example with referenced assemblies

  SourcetrailCSharpIndexer -i C:\code\SourcetrailCSharpIndexer\SourcetrailCSharpIndexer -o CSharpIndexer.srctrldb -ox -r C:\code\SourcetrailCSharpIndexer\SourcetrailCSharpIndexer\bin\Debug\net5.0

  If you re-open the database in Sourcetrail, the errors should be gone.

Screenshots

After executing the second example, open the database in Sourcetrail, select the class Program and inside that class the method Main
You should see something like this:
