Package dbus implements bindings to the D-Bus message bus system. To use the message bus API, you first need to connect to a bus (usually the session or system bus). The acquired connection then can be used to call methods on remote objects and emit or receive signals. Using the Export method, you can arrange D-Bus methods calls to be directly translated to method calls on a Go value. For outgoing messages, Go types are automatically converted to the corresponding D-Bus types. The following types are directly encoded as their respective D-Bus equivalents: Slices and arrays encode as ARRAYs of their element type. Maps encode as DICTs, provided that their key type can be used as a key for a DICT. Structs other than Variant and Signature encode as a STRUCT containing their exported fields. Fields whose tags contain `dbus:"-"` and unexported fields will be skipped. Pointers encode as the value they're pointed to. Types convertible to one of the base types above will be mapped as the base type. Trying to encode any other type or a slice, map or struct containing an unsupported type will result in an InvalidTypeError. For incoming messages, the inverse of these rules are used, with the exception of STRUCTs. Incoming STRUCTS are represented as a slice of empty interfaces containing the struct fields in the correct order. The Store function can be used to convert such values to Go structs. Handling Unix file descriptors deserves special mention. To use them, you should first check that they are supported on a connection by calling SupportsUnixFDs. If it returns true, all method of Connection will translate messages containing UnixFD's to messages that are accompanied by the given file descriptors with the UnixFD values being substituted by the correct indices. Similarily, the indices of incoming messages are automatically resolved. It shouldn't be necessary to use UnixFDIndex.
Readme
dbus is a simple library that implements native Go client bindings for the D-Bus message bus system.
This packages requires Go 1.1. If you installed it and set up your GOPATH, just run:
go get github.com/godbus/dbus
If you want to use the subpackages, you can install them the same way.
The complete package documentation and some simple examples are available at godoc.org. Also, the _examples directory gives a short overview over the basic usage.
Please note that the API is considered unstable for now and may change without further notice.
go.dbus is available under the Simplified BSD License; see LICENSE for the full text.
Nearly all of the credit for this library goes to github.com/guelfey/go.dbus.
