Data Types
interface	preprocess
	Generic interface to start preprocessing from various sources/sinks. More...

Functions/Subroutines
subroutine	preprocess_file (filepath, outputfile)
	Preprocess a file and write result to an optional output file (default: stdout) Opens the input file, determines the base filename for error messages, opens the output file if requested, and delegates to the unit-to-unit routine.
subroutine	preprocess_unit_to_file (iunit, ofile)
	Preprocess from an already-open input unit and write to a file.
subroutine	preprocess_file_to_unit (ifile, ounit)
	Preprocess a file and write to an already-open output unit.
subroutine	preprocess_unit_to_unit (iunit, ounit)
	Core preprocessing routine: read from iunit, write to ounit Sets up a clean macro environment for the top-level file, resets conditional compilation state, and calls the worker routine.
subroutine	preprocess_unit (iunit, ounit, macros, from_include)
	Worker routine that reads lines, handles continuations, comments and directives This is the main loop that:
recursive character(:) function, allocatable	process_line (current_line, ounit, filepath, linenum, macros, stch)
	Process a single (possibly continued) line – handles directives and macro expansion Responsibilities:

Variables

	Current source file name (without path)
logical	c_continue
	Flags for C-style continuation.
logical	f_continue
	Flags for Fortran-style continuation.
logical	in_comment
	Internal state flags.
logical	reprocess
	Internal state flags.
logical	stitch
	Internal state flags.
character(:), allocatable	res
	Accumulated result line buffers.
character(:), allocatable	tmp
	Accumulated temporary line buffers.
character(max_line_len)	line
	Raw input line.
character(max_line_len)	continued_line
	Raw and continued input line.
integer	iline
	Current line number position.
integer	icontinuation
	Continuation position.
