Even though the core implementation is written in C++, this does not require you to write your indexer in C++ as well. Instead you can use a language binding (e.g. see [SWIG](http://www.swig.org/)). These language bindings are already available:
* Python (via [SWIG](http://www.swig.org/))
* Java (via [SWIG](http://www.swig.org/))
If the language of your choice is not covered by this list, feel free to [open an issue](https://github.com/CoatiSoftware/SourcetrailDB/issues) or provide a pull request.

Swig is configured to generate the Python binding code as a pre-build event, so you don't need to bother with updating manually.
### Java Bindings
Requirements:
* [Java JDK](https://openjdk.java.net/) needs to be included and linked against when building the Java bindings. CMake will auto-detect your Java installation.
* [SWIG 3.0.12](http://www.swig.org/) is used to automatically generate Java binding code. Make sure that SWIG is added to your path environment variable.
If you want to build the Java bindings run:
```
$ cd path/to/SourcetrailDB
$ mkdir build
$ cd build
$ cmake -DBUILD_BINDINGS_JAVA=ON ..
$ make
```
Swig is configured to generate the Java binding code as a pre-build event, so you don't need to bother with updating manually.
### Examples
The examples help you to understand SourcetrailDB usage in practice. Please take a look at each examples README file for build and use instructions. Each example also provides a Sourcetrail project file `.srctrlprj` showing you how to use a custom indexer directly from Sourcetrail (see [Integrating with Sourcetrail](#integrating-with-sourcetrail)).

## Java API Example
### Requirements
* CMake
* C++ Compiler
* Java JDK
* SWIG
### Running from Command Line
* Run cmake with `BUILD_BINDINGS_JAVA=ON`
* Build `make`
* Copy two files from the `bindings_java` build directory into `SourcetrailDB/examples/java_api_example`:
- SourcetrailDB.jar
- Windows: `_sourcetraildb.dll`
- Linux: `lib_sourcetraildb.so`
- macOS: `lib_sourcetraildb.jnilib`
* Run example from the directory `SourcetrailDB/examples/java_api_example` with:
## Windows
```
$ javac -cp SourcetrailDB.jar src/za/co/spazzymoto/example.java
$ java -cp "SourcetrailDB.jar;src" -Djava.library.path=. za.co.spazzymoto.example --database-file-path=absolute/path/to/SourcetrailDB/examples/java_api_example/src/example.srctrldb --source-file-path=absolute/path/to/SourcetrailDB/examples/java_api_example/data/file.py
```
## Unix/macOS
```
$ javac -cp SourcetrailDB.jar src/za/co/spazzymoto/example.java
$ java -cp "SourcetrailDB.jar:src" -Djava.library.path=. za.co.spazzymoto.example --database-file-path=absolute/path/to/SourcetrailDB/examples/java_api_example/src/example.srctrldb --source-file-path=absolute/path/to/SourcetrailDB/examples/java_api_example/data/file.py
```
### Running with Sourcetrail
* Run cmake with `BUILD_EXAMPLES=ON` and `BUILD_BINDINGS_JAVA=ON`
* Build `make`.
* Open `java_api_example.srctrlprj` located in the build directory of `java_api_example` with Sourcetrail and index the project.
