sys::Obj sys::Process
Process manages spawning external OS processes.
Str[] command
Command argument list used to launch process. The first item is the executable itself, then rest are the parameters.
File? dir
Working directory of process.
Environment variables to pass to new process as a mutable map of string key/value pairs. This map is initialized with the current process environment.
OutStream? err := Env.cur().err
The output stream used to sink the process stderr. Default is to send to Env.err . If set to null, then output is silently consumed like /dev/null. Note this field is ignored if mergeErr is set true, in which case stderr goes to the stream configured via out.
InStream? in := null
The input stream used to source the process stdin. If null, then the new process will block if it attempts to read stdin. Default is null.
Int join()
Wait for this process to exit and return the exit code. This method may only be called once after run.
This kill()
Kill this process. Returns this.
new make(Str[] cmd := Str[,], File? dir := null)
Construct a Process instance used to launch an external OS process with the specified command arguments. The first item in the cmd list is the executable itself, then rest are the parameters.
Bool mergeErr := true
If true, then stderr is redirected to the output stream configured via the out field, and the err field is ignored. The default is true.
OutStream? out := Env.cur().out
The output stream used to sink the process stdout. Default is to send to Env.out . If set to null, then output is silently consumed like /dev/null.
This run()
Spawn this process. See join to wait until the process finishes and to get the exit code. Return this.
