code comments

I hate code comments that say what the code is doing but not why.
/* check for null */
if (someObj != null) {...}Really? Argh!

What's more disturbing is that C# *still* doesn't allow this:
if (!someObj) {...}
which would preclude them from having to come up with the bullsh|t "?" operator.

I really dislike code comments in general[^] X| Currently, I have a coworker who writes comments like:
// Declare a variable.
int i;
// Assign the variable.
i = 42;He doesn't do it all the time, but such comments are common practice. Learn to friggin code so you don't have to remind yourself of how to declare and assign a friggin variable! :mad:

Because the next person the poor program sees after the end user is Jesus. Edit: :-)
The language is JavaScript. that of Mordor, which I will not utter here
This is Javascript. If you put big wheels and a racing stripe on a golf cart, it's still a fucking golf cart.

Here we go :). After so many years of coding, I've learned to cull back on the wordiness of the code. Still, I have a few wonder brothers who "read code so fluently" that things get opaque pretty quick. I try to stay away from the "//declare variables" nonsense and lean toward higher level explanations of code blocks. One thing that *will* set me off is when people don't use version control. So, you'll get interspersed lines of code that are commented out with new lines of code that fix a problem. One leaves this in the source in case if you need to remember what you changed. FFS, use "show changes".

There're times when the sort of commented old code crap can be useful. Like when you were given a source dump for an ancient MFC app that the customer wants an update to and find yourself going "WTF this pile of code looks like it was obsolete even when MFC was new. C with classes every once in a while is a revolting way to write C++." for weeks on end, finding that one file that never got cleaned up and is full of commented code to create X-Windows GUI components can be enlightening in an "OH. The original version of this dinosaur was apparently a C/Slowlaris application before being ported to the then new and shiny NT4 and MFC in the late 90s." sort of way. :sigh:
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.

More like boolsh|t in this case.

IsNotNull? Also, you should not be purposely throwing an error from an extension method, as part of some divine plan. Just check if it is null or not, that is all. Leave the implementation to the calling party - this helps with code reuse (I may not want to do a
console.writeline). My 2 unsolicited cents on your post. :-DWell, I am afraid someone took me off the "divine plan" update service some years ago. Please note: 1. the code will throw an error in the Extension method only when the 'throwerror parameter is 'true, and, of course, the instance of the generic parameter T (constrained to Type 'Class) is null. 2. the code will only call Console.WriteLine when the compiler directive '#define ErrorsToConsole is included at the start of the file. One would expect this to be present only in the developer's code who is using the source. Again, keep in mind this is only an experiment. I gladly accept your 2 cents ! cheers, Bill
«There is a spectrum, from "clearly desirable behaviour," to "possibly dodgy behavior that still makes some sense," to "clearly undesirable behavior." We try to make the latter into warnings or, better, errors. But stuff that is in the middle category you don’t want to restrict unless there is a clear way to work around it.» Eric Lippert, May 14, 2008

There are only 10 types of people in the world, those who understand binary and those who don't.
He never did coding in school, maybe he's trying to make up for it? :sigh:

I am one of the other poor b*st*rd now. The original developers think their code is so beautiful and wonderful that no comment is needed to explain. They think I should ask if I do not understand. It will take longer than my lifetime to finish project this way.
You have my deepest sympathy. X|

I was always taught that code comments are to describe a process your code is doing, if it is complex and not easily understood from the existing code base - otherwise, don't comment. It has served me well, all these years, so I stick with it...very minimal commenting in my code.

I have found that "50 Specific Ways to Improve Your C#" is really good, and one of the things that the author Bill Wagner points out is that your code should be self explanatory, and not require much in comments. Good variable names helps a lot.

:thumbsup: And good function names/class names. And a alear breakdown of code into bitesized pieces. Aptly named.

I think that's what JSOP was referring to as the "bullsh|t operator".

My sympathies. Been there, hated it. Look at the bright side, though: if the job were too easy, you'd get bored. Mind you, the jury's still out on which of bored and tearing-your-hair-out-in-frustration is worse.

Yes. That and using good encapsulation. On one project they passed all 3-d point vectors as separate arguments. They also had 1000+ line methods.
