Overview of Analyzed Files

Basic stats on analyzed files

Intro

For analysis purposes we separate files in scope into several categories: main, test, generated, deployment and build, and other.

The main category contains all manually created source code files that are being used in the production.
Files in the main category are used as input for other analyses: logical decomposition, concerns, duplication, file size, unit size, and conditional complexity.
Test source code files are used only for testing of the product. These files are normally not deployed to production.
Build and deployment source code files are used to configure or support build and deployment process.
Generated source code files are automatically generated files that have not been manually changed after generation.
While a source code folder may contain a number of files, we are primarily interested in the source code files that are being written and maintained by developers.
Files containing binaries, documentation, or third-party libraries, for instance, are excluded from analysis. The exception are third-party libraries that have been changed by developers.

Main Code

All manually created or maintained source code that defines logic of the product that is run in a production environment.

The following criteria are used to filter files:

files with paths like ".*".

51 files match defined criteria (9,605 LOC, 100.0% vs. main code):

35 *.h files (7,296 LOC)
2 *.cpp files (1,660 LOC)
7 *.java files (505 LOC)
5 *.py files (96 LOC)
1 *.toml files (44 LOC)
1 *.in files (4 LOC)

" *.h" is biggest, containing 75.96% of LOC.
" *.in" is smallest, containing 0.04% of LOC.

Test Code

Used only for testing of the product. Normally not deployed in a production environment.

The following criteria are used to filter files:

files with paths like ".*/[Tt]est/.*".
files with paths like ".*/test_.*".
files with paths like ".*/[Tt]ests/.*".

17 files match defined criteria (1,983 LOC, 20.6% vs. main code):

6 *.py files (882 LOC)
5 *.java files (701 LOC)
6 *.cpp files (400 LOC)

" *.py" is biggest, containing 44.48% of LOC.
" *.cpp" is smallest, containing 20.17% of LOC.

Generated Code

Automatically generated files, not manually changed after generation.

Explore: circles | sunburst

The following criteria are used to filter files:

files with paths like ".*[.]h" AND any line of content like ".* DO NOT EDIT THIS FILE [-] it is machine generated .*".
files with any line of content like "\<\!\-\-[ ]*Generated by .*".
files with paths like ".*[.](html|html|xhtml)" AND any line of content like "[ ]*[<]meta name[=]"generator" .*".

1 file matches defined criteria (84 LOC, 0.9% vs. main code). All matches are in *.h files.

Build and Deployment Code

Source code used to configure or support build and deployment process.

The following criteria are used to filter files:

files with paths like ".*/pom[.]xml".
files with paths like ".*[.]sh".
files with paths like ".*[.]git[a-z]+".
files with paths like ".*/[.]gitignore".
files with paths like ".*/[.]gitmodules".

2 files match defined criteria (204 LOC, 2.1% vs. main code):

1 *.xml files (203 LOC)
