Regex of HASDEPENDENCY in Dependency Parsing

[alex8937]

Could you share more details of regex used in Dependency Parsing for each language?

We design different regex patterns according to the grammar characteristics of different languages.

For examples, for c language, we use #inlcude to find dependency:

def extract_includes(file_content):
    includes = set()
    include_pattern = r'#include[ \t]+"([^"]+)"|#include[ \t]+<([^>]+)>'
    for match in re.finditer(include_pattern, file_content):
        include_path = match.group(1) or match.group(2)
        includes.add(include_path)
    return includes

def find_dependencies(file_paths, contents):
    extensions = [".c", ".h"]
    file_paths = [file_name for file_name in file_paths if any(file_name.endswith(ext) for ext in extensions)]
    dependencies = []
    for file_path_A in file_paths:
        content_A = contents[file_path_A]
        if not content_A.strip():
            continue

        includes_A = extract_includes(content_A)
        for file_path_B in file_paths:
            if file_path_A != file_path_B:
                file_name_B = os.path.basename(file_path_B)
                for include in includes_A:
                    if include == file_name_B or include.endswith("/" + file_name_B):
                        dependencies.append((file_path_B, file_path_A))
                        break

    return dependencies
