if want to run those utilities in Plan 9 you don't need to worry about
speaking 9P with the underlying services -- i.e. no need for plan9/client
package. the file hierarchies for plumber, acme, draw, etc. are mounted
into the process' namespace. for example, acme's namespace is mounted on
"/mnt/acme"; so a program that is started by acme will use normal
open/read/write/close to interact with acme. that's the beauty of Plan 9.
the middle-layer packages (i.e. acme, plumb, draw) should use os.OpenFile,
File.Read/Write, etc.
for example: acme.New() can be modified like this
// New creates a new window.
func New() (*Win, error) {
fid, err := os.OpenFile("/mnt/acme/new/ctl", os.O_RDWR)
if err != nil {
return nil, err
}
buf := make([]byte, 100)
n, err := fid.Read(buf)
if err != nil {
fid.Close()
return nil, err
}
a := strings.Fields(string(buf[0:n]))
if len(a) == 0 {
fid.Close()
return nil, errors.New("short read from acme/new/ctl")
}
id, err := strconv.Atoi(a[0])
if err != nil {
fid.Close()
return nil, errors.New("invalid window id in acme/new/ctl: " + a[0])
}
return Open(id, fid)
}
etc.
