Code comments: How do you comment your code?
-
I'm busy writing a high load TCP server from absolute scratch in C# I've just started to implement the protocol I've been designing over the past few weeks and I really want to make an effort to comment this well because its quite complex and maintenance will be much easier that way, especially if other programmers need to maintain it a few years down the line. I've decided to make use of regions more than inline code comments although the in-lines are still there (usually explaining why your in a specific part of an if statement) So how do you comment your code?

It depends... If I want to make a single line comment, I put two slashes before the comment. Like so:
// comment goes hereIf I want to make a multi line comment, I do it like so:/* comment line 1 comment line 2 ... comment line n */:)Where it seems there are only borderlines, Where others turn and sigh, You shall rise!

//Function boo: Note xx
function boo
{
code
}or inside a big function
function foo
{
1st code snippet
..
// Note xy Start
2nd code snippet
// Note xy End
..
more code
}And the inline just for additions/explanations in particular things

Seems anything but stupid, to me. Some of us remember the days when writing code from pseudocode was the norm. It's amazing the number of improvements you can come up with (and logical errors you can spot) by writing down what things will do before writing the code for them.

Sometimes I don't comment. I do not wish others to change jack about things and hate it when this happens. I have 'My Version' (with comments) and the version I distribute (sans comments). Is this Paranoia?

We all know the story about the CS teacher who asked his pupils to comment their code. It was full of things like "This is slick Code" and "This works well".

I have done it as well. But not only deleting comments, sometimes editing function names (search and replace) with some cryptic / not easy names as well (of course having a relation of the equivalences just in case to be able to reverse it)

When trying to work out what needs to be done, before I actually write any proper code I do a brief Comment and Pseudo code excercise. I find that puts things into a logical order and speeds up work when I get to the nitty-gritty.

I find anybody who was coding [professionally] more than 15-20 years ago is pretty good on pre-commenting. It's the low order primates that cause me grief.

I comment the code profusely, and in the event that there is a sufficiently complex implementation, I write a separate "How It Works" document in Word, and make check that document into source control with the rest of the project.

That seems very concise, but I, unfortunately, have never written anything so complex as to warrent that. However, I shall bear it in mind if ever I do.

Group related methods in a region. 2. XML style commenting for the methods. You can also keep each method in a region of its own. This removes the scrolling required in case of huge file. 3. If the method is huge, break that into regions as well (better to split it into smaller methods). 4. Every important line/block of code should have a comment before stating what it is doing. 5. In case there are nested if/else, keep footer comments to make sure you don't have to wonder where did you missed that closing "}". 6. In case you have written some "work around" (read weird stuff), do not forget to mention the reason for it or else the other guy would mess that curse you forever. 7. In the end, read the entire file and get rid of excessive commenting.
