Detailed Description

Low-level parsing helpers and include preprocessor for the Fun parser.

This module provides character scanners, token helpers, simple string/number literal readers, a lightweight include preprocessor that can expand include directives, and mapping utilities to translate expanded line numbers back to original files for diagnostics.

Macro Definition Documentation

◆ DEFAULT_LIB_DIR

#define DEFAULT_LIB_DIR "/usr/share/fun/lib/"

Function Documentation

◆ map_expanded_line_to_include_path()

int map_expanded_line_to_include_path	(	const char *	path,
		int	line,
		char *	out_path,
		size_t	out_path_cap,
		int *	out_line )

Map a line number in expanded source back to original include path/line.

Scans the expanded text for the nearest preceding __include_begin__ marker and computes the corresponding inner line number.

Parameters

path	Path to the original top-level file that was expanded.
line	1-based line number in the expanded text.
out_path	Output buffer for the resolved file path.
out_path_cap	Capacity of out_path.
out_line	Receives 1-based line number within resolved file.

Returns: 1 on success, 0 on failure.
