From version 1.0.4.0 of PowerCommands you can call two commands using one line, using the | character, at the moment it is limited to two commands but the plan is to allow as many commands as you like in a call chain.
The code below shows an example on how it could be used, in this case I first run the command output which is a really simple command that prints out what you input in the flag --text, then we use the | to let the runtime know that one more command should be run, in this case it is the file command, I am adding a --target flag with a file name.
pipe_write_file.mp4
If the target command needs the output from the calling command the target command must implement code pickup the output, let´s take a look on how this is implemented in the FileCommand class.
The first row shows how a command can grab the result from the previous command.
var latestCommandResult = IPowerCommandsRuntime.DefaultInstance?.Latest;
If you want create a command that explore this, it could look like this.
[PowerCommandDesign(description: "Run commands that supports pipe functionality.",
example: "//First run this command and then the version command|version [PIPE] pipe")]
public class PipeCommand(string identifier, PowerCommandsConfiguration configuration) : CdCommand(identifier, configuration)
{
public override RunResult Run()
{
Console.Clear();
var result = IPowerCommandsRuntime.DefaultInstance?.Latest;
if (result == null) return Ok();
WriteLine($"Previous command: {result!.ExecutingCommand.Identifier}");
WriteLine($"Previous output length: {result!.Output.Length}");
WriteLine($"Previous command status: {result!.Status}");
WriteLine($"Previous command input: {result!.Input.Raw}");
var retVal = Ok();
return retVal;
}
}
