|
||||
=====
|
||||
|
||||
Cepko implements easy-to-use communication with CloudSigma's VMs through a
|
||||
virtual serial port without bothering with formatting the messages properly nor
|
||||
parsing the output with the specific and sometimes confusing shell tools for
|
||||
that purpose.
|
||||
|
||||
Having the server definition accessible by the VM can be useful in various
|
||||
ways. For example it is possible to easily determine from within the VM, which
|
||||
network interfaces are connected to public and which to private network.
|
||||
Another use is to pass some data to initial VM setup scripts, like setting the
|
||||
hostname to the VM name or passing ssh public keys through server meta.
|
||||
|
||||
Example usage:
|
||||
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
|
||||
"github.com/cloudsigma/cepgo"
|
||||
)
|
||||
|
||||
func main() {
|
||||
c := cepgo.NewCepgo()
|
||||
result, err := c.Meta()
|
||||
if err != nil {
|
||||
panic(err)
|
||||
}
|
||||
fmt.Printf("%#v", result)
|
||||
}
|
||||
|
||||
Output:
|
||||
|
||||
map[string]interface {}{
|
||||
"optimize_for":"custom",
|
||||
"ssh_public_key":"ssh-rsa AAA...",
|
||||
"description":"[...]",
|
||||
}
|
||||
|
||||

go.dbus
|
||||
-------
|
||||
|
||||
go.dbus is a simple library that implements native Go client bindings for the
|
||||
D-Bus message bus system.
|
||||
|
||||
### Features
|
||||
|
||||
* Complete native implementation of the D-Bus message protocol
|
||||
* Go-like API (channels for signals / asynchronous method calls, Goroutine-safe connections)
|
||||
* Subpackages that help with the introspection / property interfaces
|
||||
|
||||
### Installation
|
||||
|
||||
This packages requires Go 1.1. If you installed it and set up your GOPATH, just run:
|
||||
|
||||
```
|
||||
go get github.com/guelfey/go.dbus
|
||||
```
|
||||
|
||||
If you want to use the subpackages, you can install them the same way.
|
||||
|
||||
### Usage
|
||||
|
||||
The complete package documentation and some simple examples are available at
|
||||
[godoc.org](http://godoc.org/github.com/guelfey/go.dbus). Also, the
|
||||
[_examples](https://github.com/guelfey/go.dbus/tree/master/_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.

/*
|
||||
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.
|
||||
|
||||
Conversion Rules
|
||||
|
||||
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:
|
||||
|
||||
Go type | D-Bus type
|
||||
------------+-----------
|
||||
byte | BYTE
|
||||
bool | BOOLEAN
|
||||
int16 | INT16
|
||||
uint16 | UINT16
|
||||
int32 | INT32
|
||||
uint32 | UINT32
|
||||
int64 | INT64
|
||||
uint64 | UINT64
|
||||
float64 | DOUBLE
|
||||
string | STRING
|
||||
ObjectPath | OBJECT_PATH
|
||||
Signature | SIGNATURE
|
||||
Variant | VARIANT
|
||||
UnixFDIndex | UNIX_FD
|
||||
|
||||
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.
|
||||
|
||||
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.
|
||||
|
||||
Unix FD passing
|
||||
|
||||
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.

GoSerial
|
||||
========
|
||||
A simple go package to allow you to read and write from the
|
||||
serial port as a stream of bytes.
|
||||
|
||||
Details
|
||||
-------
|
||||
It aims to have the same API on all platforms, including windows. As
|
||||
an added bonus, the windows package does not use cgo, so you can cross
|
||||
compile for windows from another platform. Unfortunately goinstall
|
||||
does not currently let you cross compile so you will have to do it
|
||||
manually:
|
||||
|
||||
GOOS=windows make clean install
|
||||
|
||||
Currently there is very little in the way of configurability. You can
|
||||
set the baud rate. Then you can Read(), Write(), or Close() the
|
||||
connection. Read() will block until at least one byte is returned.
|
||||
Write is the same. There is currently no exposed way to set the
|
||||
timeouts, though patches are welcome.
|
||||
|
||||
Currently all ports are opened with 8 data bits, 1 stop bit, no
|
||||
parity, no hardware flow control, and no software flow control. This
|
||||
works fine for many real devices and many faux serial devices
|
||||
including usb-to-serial converters and bluetooth serial ports.
|
||||
|
||||
You may Read() and Write() simulantiously on the same connection (from
|
||||
different goroutines).
|
||||
|
||||
Usage
|
||||
-----
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/tarm/goserial"
|
||||
"log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
c := &serial.Config{Name: "COM45", Baud: 115200}
|
||||
s, err := serial.OpenPort(c)
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
n, err := s.Write([]byte("test"))
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
|
||||
buf := make([]byte, 128)
|
||||
n, err = s.Read(buf)
|
||||
if err != nil {
|
||||
log.Fatal(err)
|
||||
}
|
||||
log.Print("%q", buf[:n])
|
||||
}
|
||||
```
|
||||
|
||||
Possible Future Work
|
||||
--------------------
|
||||
- better tests (loopback etc)

Remarks:

If an application sets ReadIntervalTimeout and

ReadTotalTimeoutMultiplier to MAXDWORD and sets
|
||||
ReadTotalTimeoutConstant to a value greater than zero and
|
||||
less than MAXDWORD, one of the following occurs when the
|
||||
ReadFile function is called:
|
||||
|
||||
If there are any bytes in the input buffer, ReadFile returns
|
||||
immediately with the bytes in the buffer.
|
||||
|
||||
If there are no bytes in the input buffer, ReadFile waits
|
||||
until a byte arrives and then returns immediately.
|
||||
|
||||
If no bytes arrive within the time specified by
|
||||
ReadTotalTimeoutConstant, ReadFile times out.
