Handle includes in Fortran and C parsers - Use compiler preprocessing
Problem
The current parsing approach does not handle include files. When parsing Fortran and C code, included files need to be exposed to the wrapper because:
Include files contain important declarations and definitions that affect the parsed code
The wrapper needs access to all included files, not just the main file being parsed
Without including these files, the wrapper won't have complete information about the exposed API
Solution
Use the compiler's preprocessing step before parsing:
Call the compiler (e.g., gcc -E for C, gfortran -E for Fortran) with all necessary compilation flags
The compiler will preprocess the code, resolving all #include (C) and include (Fortran) statements
Capture the preprocessed output
Parse the preprocessed result, which now contains all expanded includes and definitions
This approach ensures we have complete information without reimplementing the preprocessor logic.
Implementation Details
For C: Use gcc -E or clang -E with appropriate flags (include paths, defines, etc.)
For Fortran: Use gfortran -E or similar with appropriate flags
Pass user-provided compiler flags to ensure correct preprocessing (e.g., -I, -D, etc.)
Capture and parse the preprocessed output
Impact
Improves accuracy of the parsing
Ensures the wrapper has complete information about the exposed API
Handles complex dependencies between header/include files
Leverages existing compiler preprocessing (no need to reimplement)
