Option to disable output of running task name

[binarykitchen]

I've been looking for a long time for a grunt option to silence some default logging.

An option to disable the output of running tasks names would be great. Especially when I want to run karma e2e tests that generates an output only when a test fails.

At the moment I see lines like these:

Running "karma:e2e_single" (karma) task

Every grunt task begins with such an output. How can I disable them? To me it looks like there is no such option. Can you add one?

You'll be able to easily customize this in the next version of Grunt. If you want to check out the progress please view: https://github.com/cowboy/node-prolog

A simple workaround for now is to just duck punch grunt.log.header = function() {} in your Gruntfile.

This might be useful to sombedy so I'll share my twisted hack which should work for most Unix/Linux terminals :)

I have written a simple task for my own usage which I run multiple times as part of a bigger task. I do not want Running "blah" task output to be seen right above the actual output so in my task's code I did:

  grunt.log.write("\x1B[1A");
  grunt.log.writeln(actualTaskOutput);

The first line outputs the ANSI escape sequence for vt100 terminals to move the cursor 1 line up and then the next write actually overwrites overwrites the Running "blah" task text (provided that you output a long enough string) ;)

Edit:
You could also move the cursor one line up ("\x1B[1A"), just clear the entire line ("\x1B[2K"), possibly write some output on it and a new line (grunt.log.writeln('some output on it') or just grunt.log.writeln()) and then start writing the task output.

Also works in Windows.
