protobuf-dt provides integration with protoc, protobuf's compiler, to compile the .proto file being currently edited and generate Java, C++ or Python code from such file. protobuf-dt creates error markers in the editor if protoc finds any errors.

Integration with protoc is disabled by default.

New in v1.2.0!

If integration with protoc is enabled, the output of protoc will be shown in Eclipse's console:

Configuring protoc integration

protoc integration can be configured at the workspace level or project level. Both types of configuration offer exactly the same options.

Before integrating protobuf-dt with protoc, you'll need to download and install the latest protobuf distribution.

Workspace preferences

To configure workspace-level protoc integration, go to the menu "Window" > "Preferences." In the "Preferences" dialog, open the "Protocol Buffer" element on the tree view on the left-hand side and select "Compiler."

1. Main Tab

In this tab, you can

1. compile a .proto file (with protoc,) every time it is saved
2. specify the path of protoc
3. specify the path of the descriptor.proto file to use when compiling .proto files (optional)

2. Options Tab

In this tab, you can

1. specify the target language for code generation
2. specify the folder where to store the generated code

3. Refresh Tab

In this tab, you can specify whether resources should be refreshed after invoking protoc.

Project preferences

To configure project-specific protoc integration, simply right-click and project and select "Properties" from the pop-up menu. Project-level preferences are exactly the same as workspace-level ones.

Note

By default, the option "Compile .proto files on save" is disabled in both workspace and project preferences.
