It may not work in cases when execution context changed from console to any other object: This is expected because console.info expects its “this” reference to be console, not window. console.info(“stuff”) stuff undefined console.info.call(this, “stuff”) TypeError: Illegal invocation console.info.call(console, “stuff”) stuff undefined This behavior is expected. https://bugs.chromium.org/p/chromium/issues/detail?id=48662
According to the documentation that you linked to, console.error and console.warn outputs to stderr. The others output to stdout. If you are doing piping or redirection from node.js the difference is important. There is a lot of JavaScript written to run in both the browser and Node.js. Having node implement the full console allows for … Read more
Use String.Format with alignment values. For example: String.Format(“|{0,5}|{1,5}|{2,5}|{3,5}|”, arg0, arg1, arg2, arg3); To create one formatted row.
What you want to do is put the console into “raw” mode (line editing bypassed and no enter key required) as opposed to “cooked” mode (line editing with enter key required.) On UNIX systems, the ‘stty’ command can change modes. Now, with respect to Java… see Non blocking console input in Python and Java. Excerpt: … Read more
You mean: Wscript.Echo “Like this?” If you run that under wscript.exe (the default handler for the .vbs extension, so what you’ll get if you double-click the script) you’ll get a “MessageBox” dialog with your text in it. If you run that under cscript.exe you’ll get output in your console window.
You can use Trace.WriteLine(“text”); This will output to the “Output” window in Visual Studio (when debugging). make sure to have the Diagnostics assembly included: using System.Diagnostics;
This can be quite easily achieved using the ProcessStartInfo.RedirectStandardOutput property. A full sample is contained in the linked MSDN documentation; the only caveat is that you may have to redirect the standard error stream as well to see all output of your application. Process compiler = new Process(); compiler.StartInfo.FileName = “csc.exe”; compiler.StartInfo.Arguments = “/r:System.dll /out:sample.exe … Read more
In the Tools -> Visual Studio Options Dialog -> Debugging -> Check the “Redirect All Output Window Text to the Immediate Window”.
That’s very nice, however in order to simulate some time passing we need to run a command that takes some time and that’s very clear in second example. However, the style of using a for loop to do some functionality forever takes a lot of device resources and instead we can use the Garbage Collector … Read more
If you’re inside a Flutter Widget, you can use debugPrint, e.g., import ‘package:flutter/foundation.dart’; debugPrint(‘movieTitle: $movieTitle’); Or, use Dart’s built in log() function import ‘dart:developer’; log(‘data: $data’);
