Types ¶
type Command ¶
type Command interface {
Shell() string
}
The Command interface is used to have specialized commands that are used for execution and logging (the latter is useful to hide the gory details of more complex commands).
type Logger ¶
type Logger interface {
Logging() string
}
The Logger interface should be implemented by commands, which hide their intent behind a series of complex shell commands. The returned string will be printed instead of the raw output of the Shell function.
type Renderer ¶
type Renderer interface {
Render(i interface{})
}
Often it is convenient to directly use values or methods of the template in the commands (using go's templating mechanism).
type StdinConsumer ¶
type StdinConsumer interface {
Input() io.ReadCloser
}
If a command needs to send something to the remote host (a file for example) the content can be made available on standard input of the remote command. The command must make sure that changed local content will reissue execution of the command (by printing the content's hash to standard output for example).
