13 extensions are included in analyses: java, gradle, properties, md, xml, sh, yaml, txt, gitignore, py, kts, bat, json
6 criteria are used to exclude files from analysis:

exclude files with path like ".*/gradle/wrapper/.*" (Gradle) (1 file).
exclude files with path like ".*/[.][a-zA-Z0-9_]+.*" (Hidden files and folders) (10 files).
exclude files with path like ".*/sokrates_.*?[.]json" (Sokrates conventions and configurations) (1 file).
exclude files with path like ".*/git[-]history[.]txt" (Git history) (1 file).
exclude files with path like ".*/git[-][a-zA-Z0-9_]+[.]txt" (Git data exports for sokrates analyses) (0 files).
exclude files with path like ".*/testdata/.*" (Test data) (66 files).

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 ".*".

170 files match defined criteria (17,888 LOC, 100.0% vs. main code):

164 *.java files (17,801 LOC)
1 *.py files (51 LOC)
5 *.xml files (36 LOC)

" *.java" is biggest, containing 99.51% of LOC.
" *.xml" is smallest, containing 0.2% 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 ".*[-]tests/.*".
files with paths like ".*[-]test[-].*".

69 files match defined criteria (22,698 LOC, 126.9% vs. main code):

66 *.java files (22,530 LOC)
3 *.gradle files (168 LOC)

" *.java" is biggest, containing 99.26% of LOC.
" *.gradle" is smallest, containing 0.74% of LOC.

Analyzers

Info about analyzers used for source code examinations.

*.java files are analyzed with JavaAnalyzer:

All basic standard analyses supported (source code overview, duplication, file size, concerns, findings, metrics, controls)

Advanced code cleaning (empty lines and comments removed for LOC calculations, additional cleaning for duplication calculations)

Unit size analysis

Conditional complexity analysis

Advanced heuristic dependency analysis (based on package names)

*.py files are analyzed with PythonAnalyzer:

All basic standard analyses supported (source code overview, duplication, file size, concerns, findings, metrics, controls)

Advanced code cleaning (empty lines and comments removed for LOC calculations, additional cleaning for duplication calculations)

Unit size analysis

Conditional complexity analysis

Basic heuristic dependency analysis

*.xml files are analyzed with XmlAnalyzer:

All basic standard analyses supported (source code overview, duplication, file size, concerns, findings, metrics, controls)

Advanced code cleaning (empty lines and comments removed for LOC calculations, additional cleaning for duplication calculations)

No unit size analysis
