Getting the stack trace or current file from Appcelerator Titanium?

Question

I want to make a logging mechanism that also includes the file that the log statement was written from.

So for instance, if I have a file:

//foo.js
log("stuff");

Then I want the log function to be able to include the file name "foo.js" in the logs.

Is this possible? I haven't been able to find anything about it anywhere.

Answer 1

You can trigger a new error and catch it internally. That way, you can access the stack trace using myError.stack , which will print a list of files that have led to your execution point. Example:

try {
    throw new Error('Trace!');
} catch (err) {
    console.log(err.trace);
}

If you have more questions, let me know!

Answer 2

As an alternative, you could throw the error and handle it in the uncaughtException event. Note that this should only be done for development purposes.

Answer 3

除了触发新错误外，另一种可能的解决方案是创建并维护自己的全局数组，该数组包含已打开的所有控制器的名称。
