1 error + 1 error = 3 errors? where is the extra one?

[c0d3r 17]

Just realized that the compiler error counts were always offset by 1,  so where is that extra one?     Are the EMBRAS... guys able to count their fingers?  if not,  I can teach them.

the third error, stay to programmer that:

• who made the "mistake" of compiling his code and didn't even pay attention to what he was doing.
• 1 + 1 + programmer drinking beer while pressing the compile button ... = 3 errors

Example?

[Stano 143]

Compilers generally try very hard if they find a bug. Then they don't know when to stop. D10.4 has made significant progress in this direction. The number of reported errors is several orders of magnitude lower.
Even so, it is recommended to believe only the first mistake and ignore the others.
I wouldn't make it a science.

Create a new vcl application, drop 2 labels, and make ONE label name typo in Oncreate event.  When compiling, it said there were 2 errors in the codes:

Actually there are two errors:

1. undeclared identifier
2. cannot compile unit

Seems to be pretty correct in my view.

can't compile the unit is not an error that should be included,  its a result due to that ONE typo error in the codes.  The errors should be reported exactly as whats in your codes.

This is so important! We must leave no stone unturned in our battle to persuade Embarcadero to change this!

Why are you eliminating the possibility of the compiler been schizophrenic ?

 

Please don't deny a compiler his simple rights.

[Uwe Raabe 2057]

After all, the first error was actually made by the developer, not the compiler.

thanks @Uwe Raabe for confirm my suppose:

It's the same result in 10.2.3, not sure which version you have. I guess Delphi has it's own broken windows theory 😉

Be positive. You can kill two birds with one stone.

Leaving aside my sarcastic response above, I think a majority of Delphi users will not regard this as an issue.

 

What happens here is that the compiler reaches a point where the errors which have been encountered so far mean that it decides to abort compilation of this unit. And it reports that decision as an error. It's been this way since the dawn of time. Nobody, but nobody, cares about precisely how many errors there are in their code. There are two states that matter:

1. The code has no errors.
2. The code has some errors.

Were the compiler to do what you ask, and not write the "cannot compile unit" error, and report a single error, you would not know that there was but a single error. Because the compiler had given up and any errors that are present in the code which follows the point at which the compiler aborted, would not be counted.

 

It is useful for the compiler to report counts of hints and warnings, since these values are meaningful. Counts of errors are, as I have shown above, are not.

 

That this even has to be explained astounds me.

[Mike Torrettinni 198]

Looks like Warnings is off by 1 too - well it counts same Warning 2x:

 

 

@c0d3r I guess you started the scrutiny of Compile window... looks even more broken, unfortunately

 

I'm using Delphi 10.2.3, I hope newer versions have this improved.

The complete lack of perspective here is breathtaking.

Why is this a problem ?

 

It is basic physics, an empty skull might generate echo, sometimes i wrote things twice or get an idea in double folded due the desolation.

You don't think it should report 1 Warnings if there is only1 Warning? Why it counts the same warning 2 times?

Hints work correct, 1 Hint = 1 reported Hint.

I don't for now and for a warning or hint, not important at all, in fact it does show the compiler have ugly workaround(s) and cut corners in its generated messages proce4ssing, but nothing serious or worth the time, even to write this exact post.

Since I prefer short blogs over books, I suggest googling: " is attention to detail useful?" and you will find many blogs and even books that might be helpful to you, in software development and also in life.

Perhaps this explains the focus on tiny details and missing the bigger picture. 

 

We all know about the importance of attention to detail. Of course the compiler spitting out two warnings rather than one here is imperfect. But it has no impact on any user. It's trivial. Delphi has so many big issues and this is what gets people heated?!

You don't read blogs? I like to, usually is condensed topic vs books.

Sure. But if that's all you read then you don't see the big picture.

You are pretty vague here... big picture of what, what are you talking about?

[David Heffernan 2345]

The fact that you regard this topic as important. That you feel it's important to count errors beyond one. The fact that sometimes delphi emits two warnings for the same issue. None of these things matter.
