callstack

Access to v8's "raw" CallSites. This module provides the following "magical" global getters:

  • __stack array CallSite objects starting from the callee
  • __line the current line number

Installation

$ npm install callsite

__stack

For details on the v8 CallSite objects view the stack trace api docs, for example __stack[0].getFileName().

require('callsite');

foo();

function foo() {
  bar();
}

function bar() {
  baz();
}

function baz() {
  __stack[0].fun == baz;
  __stack[1].fun == bar;
  __stack[2].fun == foo;
}

__line

Returns the current lineno:

require('callsite');
console.log('foo')
console.log('bar')
console.log(__lineno) // => 4

Why?

Because you can do weird, stupid, clever, wacky things.
