Using 'task_err' event

[rakhmanoff]

There is not so much documentation about using 'task_err' event that user can call like this

task.emit('task_err', err)

At first I thought that it is undocumented inner feature, but the code doesn't enit it itself. It is possible to make a situation with task_err clearer?

I don't understand what the question is here. This doesn't seem to be related to run-sequence.

[rakhmanoff]

When I am trying to interrupt whole sequence in the process of execution then task.emit('task_err', err) is only one possible way, as I understand. It works and I think that this method can be useful for others and I would like to see this method in the docs.

Or may be there is another way to interrupt sequence of task in the process of execution?

[OverZealous]

I don't know why you'd want to interrupt a sequence—it should automatically stop if any task throws an error, which is a gulp or node issue.

I'm using the gulp-less plugin with run-sequence. gulp-less is running into an error with invalid less, but the sequence keeps on running. It's not clear if gulp-less plugin is not behaving properly, or if run-quence isn't stopping the sequence as expected.

My issues with gulp-less and run-sequence turned out to be a general design issue with how gulp handles errors, not any one particular plugin. This issue from gulp-typescript discusses it more:
