Plugin RPC Generator
|
|
====================
|
|
|
|
Generates go code from a Go interface definition for proxying between the plugin
|
|
API and the subsystem being extended.
|
|
|
|
## Usage
|
|
|
|
Given an interface definition:
|
|
|
|
```go
|
|
type volumeDriver interface {
|
|
Create(name string, opts opts) (err error)
|
|
Remove(name string) (err error)
|
|
Path(name string) (mountpoint string, err error)
|
|
Mount(name string) (mountpoint string, err error)
|
|
Unmount(name string) (err error)
|
|
}
|
|
```
|
|
|
|
**Note**: All function options and return values must be named in the definition.
|
|
|
|
Run the generator:
|
|
|
|
```bash
|
|
$ pluginrpc-gen --type volumeDriver --name VolumeDriver -i volumes/drivers/extpoint.go -o volumes/drivers/proxy.go
|
|
```
|
|
|
|
Where:
|
|
- `--type` is the name of the interface to use
|
|
- `--name` is the subsystem that the plugin "Implements"
|
|
- `-i` is the input file containing the interface definition
|
|
- `-o` is the output file where the generated code should go
|
|
|
|
**Note**: The generated code will use the same package name as the one defined in the input file
|
|
|
|
Optionally, you can skip functions on the interface that should not be
|
|
implemented in the generated proxy code by passing in the function name to `--skip`.
|
|
This flag can be specified multiple times.
|
|
|
|
You can also add build tags that should be prepended to the generated code by
|
|
supplying `--tag`. This flag can be specified multiple times.
|
|
|
|
## Known issues
|
|
|
|
## go-generate
|
|
|
|
You can also use this with go-generate, which is pretty awesome.
|
|
To do so, place the code at the top of the file which contains the interface
|
|
definition (i.e., the input file):
|
|
|
|
```go
|
|
//go:generate pluginrpc-gen -i $GOFILE -o proxy.go -type volumeDriver -name VolumeDriver
|
|
```
|
|
|
|
Then cd to the package dir and run `go generate`
|
|
|
|
**Note**: the `pluginrpc-gen` binary must be within your `$PATH`
