DSUnixTask

DSUnixTask is a library for Mac OS X which allows to launch and interact with awesome looking UNIX tasks.

Features:

• Simple interface based on blocks.
• Process standard output and standard error in real-time.
• Easily send messages to standard input.
• Execute tasks either as sub-processes or through an XPC service.
• Execute throughout the user shell.
• Logging.

Running a task as a sub-processes

Podfile:

pod 'DSUnixTask/Core'

Usage:

#import <DSUnixTaskSubProcessManager.h>

- (void)runTasfk {
  [[DSUnixTaskSubProcessManager sharedManager] setLoggingEnabled:TRUE];
  DSUnixTask *task = [DSUnixTaskSubProcessManager shellTask];
  [task setCommand:@"/bin/cat"];
  [task setStandardOutputHandler:^(DSUnixTask *task, NSString *output) {
    NSLog(@"%@", output);
  }];
  [task launch];
  [task writeStringToStandardInput:@"Hi!"];
}

XPC

XPC Service:

To create the target for the XPC service:

1. Use the XPC Service template.
2. Add a Copy Files build phase to the application.

• Destination: Wrapper.
• SubPath: Contents/XPCServices.
• Copy the XPC service product

3. Add a dependency to your application’s build phases on the XPC Service.

Podfile:

target 'MyApp' do
  pod 'DSUnixTask/XPCClient'
end

target 'XPCservice' do
  pod 'DSUnixTask/XPCService'
end

Usage:

Client:

#import <DSUnixTaskXPCManager.h>

- (void)runTask {
  [[DSUnixTaskXPCManager sharedManager] setServiceBundleIdentifier:@"com.compary.xpc-bundle-name"];
  [[DSUnixTaskXPCManager sharedManager] setLoggingEnabled:TRUE];
  DSUnixTask *task = [DSUnixTaskSubProcessManager shellTask];
  [task setCommand:@"/bin/cat"];
  [task setStandardOutputHandler:^(DSUnixTask *task, NSString *output) {
    NSLog(@"%@", output);
  }];
  [task launch];
  [task writeStringToStandardInput:@"Hi!"];
}

Service:

#include <Foundation/Foundation.h>
#import "DSUnixTaskServiceMain.h"

int main(int argc, const char *argv[]) {
  runUnixTaskXPCService();
}
