Code Metrics
-
Decided to run code metrics on my current "big" VS project. I felt I had a "huge" code base. My 31K of source code (it felt like more) amounted to little more than 7300 lines of "Executable" code. Years ago, I scoffed when I read the average programmer writes only about 100 lines of bug-free code per day.

"Lines" is not a valid metric for modern languages.

I would not say it is an invalid metric. It's just not an accurate metric. Define modern languages. I can easily write way more than 100 lines of bug free C code a day when deep into a project. My last project was 1.2 megabytes of source code, not including libraries. Not sure how many lines. Maybe I am just a wordy programmer.

Counting statements is more worthwhile than counting "lines". And even then, it depends on what one considers to be a "statement".

Any language which doesn't have a 1:1 relationship between a "line" and a statement. I suppose that really only assembly code written on cards had this distinction in the first place. Although "lines" wouldn't apply to card-based systems, but only to VT- and printer-based systems. Even BASIC (Dartmouth, 1964) focuses on statements rather than lines and "line numbers" are primarily for specifying the order in which the statements are to be executed rather than to define a "line of code". And, of course, more modern implementations of BASIC-type languages don't require line numbers at all.

Visual Studio did the "counting".
Quote:
Lines of Executable code - Indicates the approximate number of executable code lines or operations. This is a count of number of operations in executable code. This metric is available starting in Visual Studio 2019 version 16.4 and Microsoft.CodeAnalysis.Metrics (2.9.5). The value is typically a close match to the previous metric, Lines of Code, which is the MSIL-instruction-based metric used in legacy mode.

You are not average or "normal"
M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.
I find that it varies. Application level, more than that. Framework level can be a different story.

That code must be well commented to get below a 1:4 ratio! I was also surprised when I first heard about the 100 lines per day. Actually, I heard it as 50 to 75, which might be even more accurate.

The fox knows many things, but the hedgehog knows one big thing.I have a lot of (UWP) XAML; perhaps 25-35%. And don't know if it's considered "executable code" since it's (mostly) declarative; same with simpler properties.

The problem with this is that you can't really decide if it was bug free until years later. If my '100 lines' written today causes someone to spend four days fixing something in two years, then my average drops to 25 lines for that day.

It's not rare that I write 10 lines of code a week - much of my time is spent fixing issues in a huge codebase that has a lot of technical debt in which you spend pretty much all of the time reading or debugging the code.

The metric is for released code, meaning that it has been thoroughly tested and integrated.

I know line count isn't considered a useful metric, but I did one on our current product a while back out of curiosity. The 800-lb gorilla in the room is 2.5 million executable lines.
