simple_include_counter

Very simple include analyzer.

How it works

1. Reads all .h/.cpp files from given directories
2. Looks for #include xxx directives
3. Builds an include tree
4. Analyzes the tree
5. Prints to stdout in LibreOffice-friendly way (simply copy-paste into Calc)

Extracted info for each file

1. Size in bytes / lines / lines of code
2. List of includees, sorted in most-included order
3. Total direct/indirect inclusions
4. Contribution to compilation, both self and self + includes

Pain points

1. Ignores preprocessor macros, but repsects comments
2. Does not seek out system/missing headers, assumes each to be 1 code line long with no includes
3. Fails if there's a recursive dependency

Usage

cargo run --release -- input/dir/1/ input/dir/2/ input/dir/3/ > ~/Desktop/report.txt

Then copy contents of report.txt and paste into LibreOffice Calc.
