underscoreunderscore

Underscore Underscore gives you magic variables to figure out what file (or line or column) you are in, get a stack trace, or know what code called the current file. Sometimes you just need node's __file magic variable or console.trace() function.

npm install underscoreunderscore

Note

There are other approaches to this in node by using the __file global variable and the console.trace() function. For getting true cross-browser functionality, you might want something like this: https://github.com/eriwen/javascript-stacktrace

Across browsers and node however, this is how you get a stack trace

function(){{ try { throw Error(''); } catch(err) { return err; } }; };

That'll give you a stack trace (as a string), but for just the relevant data, __ comes to the rescue.

Setup

npm install -g underscoreunderscore
var __ = require("underscoreunderscore");
__.init();

Getting Info

You can get files like this:

__.trace.files;

You can get the whole stack trace like this:

__.trace.list;

You can get the whole file (+line and column numbers) like this:

__.file;
__.line;
__.column;

Lastly, you can grab the filename that executed code before like this:

var callingFile  = __.caller;
callingFile.file;
callingFile.line;
callingFile.column;
