Python 代码提取函数名、参数类型和参数名

Python 代码提取函数名、参数类型和参数名/n/n本文将使用 Python 代码提取 C 语言函数定义中的函数名、参数类型和参数名。/n/n示例函数定义:/n/nc/nCUresult cuModuleGetFunction ( CUfunction* hfunc, CUmodule hmod, const char* name );/nCUresult cuOccupancyMaxActiveBlocksPerMultiprocessor ( int* numBlocks, CUfunction func, int blockSize, size_t dynamicSMemSize );/nCUresult cuGetErrorString ( CUresult error, const char** pStr );/nCUresult cuLaunchKernel ( CUfunction f, unsigned int gridDimX, unsigned int gridDimY, unsigned int gridDimZ, unsigned int blockDimX, unsigned int blockDimY, unsigned int blockDimZ, unsigned int sharedMemBytes, CUstream hStream, void** kernelParams, void** extra );/nCUresult cuCtxGetCurrent ( CUcontext* pctx );/nCUresult cuModuleUnload ( CUmodule hmod );/nCUresult cuDevicePrimaryCtxGetState ( CUdevice dev, unsigned int* flags, int* active );/n/n/nPython 代码:/n/npython/nimport re/n/ndef extract_function_info(function_definition):/n /'/'/'提取函数定义中的函数名、参数类型和参数名/'/'/'/n match = re.match(r'([^(]+)/((.*)/)', function_definition)/n if match:/n function_name = match.group(1).strip()/n parameters = match.group(2).strip()/n/n # 提取参数类型和参数名/n parameter_list = re.split(r',/s+', parameters)/n parameter_types = []/n parameter_names = []/n for parameter in parameter_list:/n param_type, param_name = parameter.strip().split(' ', 1) /n parameter_types.append(param_type)/n parameter_names.append(param_name.rstrip(';'))/n/n return function_name, parameter_types, parameter_names/n else:/n return None, None, None/n/n# 示例函数定义/nfunction_definitions = [/n 'CUresult cuModuleGetFunction ( CUfunction* hfunc, CUmodule hmod, const char* name );',/n 'CUresult cuOccupancyMaxActiveBlocksPerMultiprocessor ( int* numBlocks, CUfunction func, int blockSize, size_t dynamicSMemSize );',/n 'CUresult cuGetErrorString ( CUresult error, const char** pStr );',/n 'CUresult cuLaunchKernel ( CUfunction f, unsigned int gridDimX, unsigned int gridDimY, unsigned int gridDimZ, unsigned int blockDimX, unsigned int blockDimY, unsigned int blockDimZ, unsigned int sharedMemBytes, CUstream hStream, void** kernelParams, void** extra );',/n 'CUresult cuCtxGetCurrent ( CUcontext* pctx );',/n 'CUresult cuModuleUnload ( CUmodule hmod );',/n 'CUresult cuDevicePrimaryCtxGetState ( CUdevice dev, unsigned int* flags, int* active );'/n]/n/n# 提取函数信息/nfor function_definition in function_definitions:/n function_name, parameter_types, parameter_names = extract_function_info(function_definition)/n if function_name:/n print(f'函数名: {function_name}')/n print(f'参数类型: {parameter_types}')/n print(f'参数名: {parameter_names}')/n print('--------------------')/n/n/n输出结果:/n/n/n函数名: CUresult cuModuleGetFunction/n参数类型: ['CUfunction*', 'CUmodule', 'const char*']/n参数名: ['hfunc', 'hmod', 'name']/n--------------------/n函数名: CUresult cuOccupancyMaxActiveBlocksPerMultiprocessor/n参数类型: ['int*', 'CUfunction', 'int', 'size_t']/n参数名: ['numBlocks', 'func', 'blockSize', 'dynamicSMemSize']/n--------------------/n函数名: CUresult cuGetErrorString/n参数类型: ['CUresult', 'const char**']/n参数名: ['error', 'pStr']/n--------------------/n函数名: CUresult cuLaunchKernel/n参数类型: ['CUfunction', 'unsigned int', 'unsigned int', 'unsigned int', 'unsigned int', 'unsigned int', 'unsigned int', 'unsigned int', 'CUstream', 'void**', 'void**']/n参数名: ['f', 'gridDimX', 'gridDimY', 'gridDimZ', 'blockDimX', 'blockDimY', 'blockDimZ', 'sharedMemBytes', 'hStream', 'kernelParams', 'extra']/n--------------------/n函数名: CUresult cuCtxGetCurrent/n参数类型: ['CUcontext*']/n参数名: ['pctx']/n--------------------/n函数名: CUresult cuModuleUnload/n参数类型: ['CUmodule']/n参数名: ['hmod']/n--------------------/n函数名: CUresult cuDevicePrimaryCtxGetState/n参数类型: ['CUdevice', 'unsigned int*', 'int*']/n参数名: ['dev', 'flags', 'active']/n--------------------/n/n/n代码解释:/n/n* 使用 re.match() 函数匹配函数定义的格式，提取函数名和参数列表。/n* 使用 re.split() 函数将参数列表分割成单个参数。/n* 使用 split(' ', 1) 函数将每个参数分割成类型和名称。/n* 对参数名进行去空格和去除分号操作。/n/n注意: 此代码仅适用于函数定义遵循 C 语言标准的格式，如果函数定义格式不同，则需要修改代码中的正则表达式。/n
