What is that Unicode symbol above the ProGet ad?

Maciejasjmj · 2015-06-08 Reply Admin

U+F729 PRIVATE USE CODEPOINT

This is a Private Use codepoint. That is, it is deliberately not assigned to any character. It was added to Unicode in version 1.1 and belongs to the block Private Use Area.

The glyph is not a composition. It has a Ambiguous East Asian Width. In bidirectional context it acts as Left To Right and is not mirrored. In text U+F729 behaves as Unknown regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

I think I want to require that this pattern not occur in my codebase.

anonymous234 · 2015-06-08 Reply Admin

How do you call stuff on it then? Do you have to do another 40 levels of if every time?

Kuro · 2015-06-08 Reply Admin

Clearly a loop is in order here:

var var_underscore = "";
for(var i = 1; i <= 40; i++){
    var_underscore += "_";
    if(eval(var_underscore)){
        eval(var_underscore + "= require('lodash')");
        break;
    }
}

You fool. That bug is only there to protect the submitter. If anybody from his workplace ever mentions this article, he can simply say "Nah, our codebase is way better. Look at line 39".

It's practically a reqeirement for code like that.

Reply 1: This was done for a bet. Right?

Reply 2: I would like to see the original code for this! I find difficult to credit, even with a Grand Master of WTFy, that this number of consecutive "ifs" could be typed without causing near fatal RSI.

Reply 3: Unless I am seriously mistaken: This can be refactored to _ = require('lodash') because if it fails the first test, it will be loaded and assigned to itself any way. Yes. I know. The inverse of this (reply) is that there is a "one in a million" chance that 'lodash' won't be needed, and "...as everybody knows, one in a million chances happen all the time..."

Unless........

In an extremely [insert additional / better adjectives here] unlikely series of events you need to use 'reqeire' (nod to @Julia, @boomzilla) or the slightly less rare occasion when you would have to get a second opinion (nod to @sehetw)

BaconBits · 2015-06-08 Reply Admin

Clearly this should be corrected to:

do {
    _ = require('lodash');
} while (!_);

This is much easier to maintain since it's shorter, and won't suffer from the obvious 39th failure, 40th success bug that a for loop would.

This code is guaranteed to succeed!

seriously, i can think of no defensible reason for that monstrosity to exist.

Even IF there really is some batshit insane reason for lodash to be loaded into that many variables the code at worst should be:

_ = \
__ = \
___ = \
____ = \
_____ = \
______ = \
_______ = \
________ = \
_________ = \
__________ = \
___________ = \
____________ = \
_____________ = \
______________ = \
_______________ = \
________________ = \
_________________ = \
__________________ = \
___________________ = \
____________________ = \
_____________________ = \
______________________ = \
_______________________ = \
________________________ = \
_________________________ = \
__________________________ = \
___________________________ = \
____________________________ = \
_____________________________ = \
______________________________ = \
_______________________________ = \
________________________________ = \
_________________________________ = \
__________________________________ = \
___________________________________ = \
____________________________________ = \
_____________________________________ = \
______________________________________ = \
_______________________________________ = \
________________________________________ = require('lodash');

Modules are cached after the first time they are loaded. This means (among other things) that every call to require('foo') will get exactly the same object returned, if it would resolve to the same file.
Multiple calls to require('foo') may not cause the module code to be executed multiple times.

loose · 2015-06-08 Reply Admin

I'm sure that some, or most, of you have come across the acronym PEBKAC in relation to Bug / Support writeups. Or perhaps the less flattering "finger trouble" observation.

That being so. Can I suggest that "judicious use" be in the form as used by various organised (non-legal) affiliations. I.e. One finger at a time, leaving the thumbs until last?

Hold on though, I have heard the excuse "...all thumbs today...". So perhaps we should start with them and eradicate the issue at the outset?

pompo500 · 2015-06-08 Reply Admin

Am I the only one to spot the ReferenceError? I.e. the code should crash anyway when it tries to reference a variable that doesn't exist..

You could use window[underscore] to get rid of the eval.
