As far as I know, the compiler treats that code the same as this:
{
string data = inputStream.ReadToEnd();
SomeClass myObj = JsonConvert.Deserialize(data)
var processed = Process(myObj);
return JsonConvert.SerializeObject(processed);
}even if it didn't precisely, at least you can debug it one step at a time. You could also do this if you had the itch (but it is fairly pointless:
{
#if DEBUGstring data = inputStream.ReadToEnd(); SomeClass myObj = JsonConvert.Deserialize(data) var processed = Process(myObj); return JsonConvert.SerializeObject(processed);#else
return JsonConvert.SerializeObject(Process(JsonConvert.Deserialize(inputStream.ReadToEnd())));#endif

I agree - the Debug directive is a really bad idea in my opinion as you now have two sets of code to maintain whenever you make a change.

Such a PITA to inspect the intermediate results when debugging a problem. Is it bad data in the input? Is it bad data being produced by
Process? Does the output JSON look like what the client is expecting? Wouldn't you want to do some validation before handing off toProcess? What about atry-catchif the deserialization fails?

Thank you for this comment… Recently I took over some relatively big Java/Eclipse/Tomcat projects and I see such things all over the place … I even have no time to change this but it should be changed, of course :-) It's the mindset indeed of such "devs" that is totally wrong … BR,

That was an "in the interest of completeness" thing.

I hate code like that. I hate it more when I submit code for a code review and I'm told to do things like that. I quite like code like;
Product p = GetProduct(params);
return p;I know that GetProduct returns a Product class and the code lets me debug to see what "p" is. Invariably someone who "knows better" will tell me to use "var" or more likely just "return GetProduct". The reason it annoys me so is that when it comes down to compiled code it makes no difference. Optimisers render the output the same. I remember in one job the tech lead had a hard-on for defining constants in their own classes (nothing wrong with that) but declaring them as static strings. I said we should use constants instead, I then began to explain "Because the compiler...." and he cut me off there saying "I don't care what the compiler does, we shouldn't change our code due to the compiler." Ok....strings it is then.

I have found that writing code that is easier to debug is an idea that contradicts some of the more modern suggested coding patterns. I am someone who likes to use LINQ and lambdas but admit that sometimes it doesn't make debugging particularly easy.

Frankly, I've been doing similar stuff myself quite frequently albeit after verifying that all the building blocks work. A stack trace of the exception being thrown usually helps debugging when something truly unexpected happens, although I wouldn't consider Deserialie(UserProvidedData) an overly valid use case for such one-liners.

I have found myself a few times in C# and JavaScript when debugging that I needed to add a return line just to break point inside some anon function. It's a bit nice once in line breaking was added, but I do like the push to split up code for more readable instead of compact lines.

Or it's just because so many "developers" do not learn or understand debugging. When things don't work they just open a QA.
When the guy who wrote the code has to spend an half an hour figuring out what the code actually does, is it a lack of debugging skill on the other people's part?

Richard, I'm guessing you never had to deal with code that was complex enough that, some 3 months after writing it, the author had to figure out what he wrote? If so, count your blessings.

the y2k bug come to my mind. on a 8bit computer one byte per date is a huge space optimization, but i don't believe that mainframe COBOL programmers had to be that careful. also, i remember reading about an "optimization" of the old day ms-dos assembly programmers using the inability of i8086 to address more than 1MB so they wouldn't mind generating segment:offset addresses that past the megabyte barrier, because it will roll over and map into the address space of the zeroth+ segment. this of course caused latter compatibility issues. there was a similar man made "optimization" problem on the first mc68000 Amiga's, but i don't recall enough info to check what was the trick there.

Some IDE's have options to remove local variables. Don't ask me why! I like them for debug STOP locations as the poster prefers. I also like them for readability and documentation. Boolean summaryDescription = (super nasty Boolean expression with 4-8 components); if (summaryDescription) { handleIt(); } An ex-team member used to have their IDE preference to collapse these out of existence. I hated looking at my code after they had performed some minor tweak on my code along with a "reformat".

Absolutely disgusting, this is the recipe CREATE legacy shit right from the start. I can't even imagine the hacks Microsoft must have had to do keep old Win32 apps working in a modern OS.

I feel your pain. I find always difficult to understand others code, even well written one (a former workmate wrote a
C++library without comments, because 'clean code explains itself'. Well 'clean code' doesn't explain its rationale at all). Hence byzantine statements are the last thing I need. Anyway, I suppose my code might look byzantine to other people.Actually that C++ developer was correct in his belief in clean code explaining itself. However, "clean code" is only truly clean when a less experienced person can easily understand it. If you are a competent developer and found difficulties with understanding this person's code, than it is that developer who did not understand that his code was not as "clean" as he believed. Obviously, it was clean to him because he could easily understand it but he didn't take into account that someone else may not. Truly clean code means that the code is written with the most basic syntax available that will process the task efficiently. However, many developers believe their code is clean today simply because they wrote it in a legible manner while still using a lot of syntax sugar that vendors come up with in their compilers to make things simpler. Surprise, surprise! The result is exactly what you are complaining about... And with good reason...
