Delphi – D2010 compiled line count discrepancy

delphidelphi-2010line-count

When building a project there are two places where source line count is reported:

On the compile progress dialog
Under Project | Information

In Delphi 2007 these two numbers were identical for the project we are building.

In Delphi 2010 these two numbers are wildly different. The (1st) count is larger by a count of 1 million lines or 40%. The (2nd) count is close enough to the Delphi 2007 count to be satisfied the correct files are being built accounting for code changes in porting to D2010. Alternative versions of source files simply do not exist in the build environment.

So the question is:

Why are 1st and 2nd line count so drastically different in D2010 when they were understandably identical in D2007?

Why does line count change so much from D2007 to D2010?

We've investigated this, and it is a bug. It came as a result of shifting to MS Build. We've fixed it in our current build.

The correct number is the one in the Project Information menu. The one that is reported in the compiling dialog is, well, an "approximation".

I've found powershell useful for this. I consider LoC to be a pretty bogus metric anyway, so I don't believe anything more formal should be required.

From a smallish solution's directory:

PS C:\Path> (gci -include *.cs,*.xaml -recurse | select-string .).Count
8396
PS C:\Path>

That will count the non-blank lines in all the solution's .cs and .xaml files. For a larger project, I just used a different extension list:

PS C:\Other> (gci -include *.cs,*.cpp,*.h,*.idl,*.asmx -recurse | select-string .).Count
909402
PS C:\Other>

Why use an entire app when a single command-line will do it? :)
