Function ProcessManager.collectCommandOutput
Run a command and pass its output to a callback
void collectCommandOutput
(
void delegate(Process*, const(char)[]) outputProcessor,
string[] cmdline...
);
Run a command with the supplied command line. Call outputProcessor
whenever the command outputs anything on
stdout or stderr.
In addition to those, outputProcessor gets called three more times. The first time is right before the process is
started (with output
set to empty). This allows outputProcessor to do any additional manipulations (such as
redirecting the input). This can be tested for because child
is 0.
The second time is when the output closes. Again, this call will have a output
set to an empty range.
The third time is after the process has already exit. This can be tested for because child
will be
false.
