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.

326 files

The following criteria are used to filter files:

files with paths like ".*".

326 files match defined criteria (57,838 LOC, 100.0% vs. main code):

226 *.h files (35,525 LOC)
73 *.cpp files (21,131 LOC)
1 *.i files (414 LOC)
5 *.js files (245 LOC)
16 *.cmake files (239 LOC)
2 *.py files (237 LOC)
3 *.css files (47 LOC)

" *.h" is biggest, containing 61.42% of LOC.
" *.css" is smallest, containing 0.08% of LOC.

Test Code

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