ExpectImpl

ExpectImpl spawns a process in a Spawn object. You then call expect("desired output"); sendLine("desired Input"); to interact with said process

class ExpectImpl (

OutputRange

) if (

isOutputRange!(OutputRange, string)

) {

OutputRange _sink;

this(string cmd, OutputRange sink);

this(string cmd, string[] args, OutputRange sink);

int expect(string toExpect);

int expect(string toExpect, Duration timeout);

void sendLine(string command);

void send(string command);

void read(Duration timeToWait = 150.msecs);

void readAllAvailable();

Duration timeout [@property setter];

long timeout [@property setter];

auto timeout [@property getter];

string before [@property getter];

string after [@property getter];

}

Constructors

this this(string cmd, OutputRange sink): Constructs an Expect that runs cmd with no args
this this(string cmd, string[] args, OutputRange sink): Constructs an Expect that runs cmd with args On linux, this passes the args with cmd on front if required On windows, it passes the args as a single string seperated by spaces

Destructor

~this ~this(): Calls the spawns cleanup routine.

Members

Functions

expect int expect(string toExpect): Expects toExpect in output of spawn within Spawns timeout
expect int expect(string toExpect, Duration timeout): Expects toExpect in output of spawn within custom timeout
read void read(Duration timeToWait = 150.msecs): Reads data from the spawn This function will sleep for timeToWait' Duration if nothing was read first time timeToWait is 50.msecs by default
readAllAvailable void readAllAvailable(): Reads all available data. Ends when subsequent reads dont increase length of allData
send void send(string command): Sends command to the pty
sendLine void sendLine(string command): Sends a line to the pty. Ensures it ends with newline

Properties

after string after [@property getter]: Reads and then returns all data after the last succesfull expect. WARNING: May block if spawn is constantly writing data
before string before [@property getter]: Returns all data before the last succesfull expect
timeout Duration timeout [@property setter]: Sets the default timeout
timeout long timeout [@property setter]: Sets the timeout to t milliseconds
timeout auto timeout [@property getter]: Returns the timeout
