GoDart is a set of experimental, actively being developed, Go bindings for libdart.
At the moment, GoDart contains a single package, cdart,
which implements a very thin wrapper over Dart's C API.
cdart will likely receive some extension in the future, but this
package can be considered reasonably stable for the time being.
For actively developing against, use the v0.1.0-alpha snapshot.
cdart is rather raw at the moment, mapping directly from C
types/functions into Go types/functions, and dispatching into
C on every individual call.
A basic example:
package main
import "fmt"
import "github.com/cfretz244/godart/cdart"
func main() {
pkt, _ := cdart.NewObjectPacket()
pkt.InsertStringField("hello", "world")
pkt.InsertIntegerField("answer", 42)
pkt.InsertDecimalField("pi", 3.14159)
pkt.Finalize()
bytes, _ := pkt.ToBytes()
rebuilt, _ := cdart.FromBytes(bytes)
str, _ := pkt.ToJSON()
rstr, _ := rebuilt.ToJSON()
fmt.Println(str)
fmt.Println(rstr)
}
// => {"pi":3.14159,"hello":"world","answer":42}
// => {"pi":3.14159,"hello":"world","answer":42}More detailed examples of cdart usage can be found in the tests.
Invoking C code presents significant call overhead in Go,
and so the intention is for a second package to be added, dart,
which will serve as the client-facing API layer.
The purpose of the dart package is both to present an idiomatic
Go interface, but also to decrease the cost of calling into
C extensions by lazily constructing and caching objects received
from the cdart package.
