Also provides the 'find_executable()' to search the path for a given executable name. � N)�DistutilsPlatformError�DistutilsExecError)�DEBUG)�log� c C sN t | �} tjdkr"t| ||d� n(tjdkr<t| ||d� ntdtj ��dS )a� Run another program, specified as a command list 'cmd', in a new process. 'cmd' is just the argument list for the new process, ie. cmd[0] is the program to run and cmd[1:] are the rest of its arguments. There is no way to run a program with a name different from that of its executable. If 'search_path' is true (the default), the system's executable search path will be used to find the program; otherwise, cmd[0] must be the exact path to the executable. If 'dry_run' is true, the command will not actually be run. Raise DistutilsExecError if running the program fails in any way; just return on success. �posix)�dry_run�ntz1don't know how to spawn programs on platform '%s'N)�list�os�name� _spawn_posix� _spawn_ntr )�cmd� search_path�verboser � r �4/opt/alt/python37/lib64/python3.7/distutils/spawn.py�spawn s r c C s. x(t | �D ] \}}d|kr d| | |< q W | S )z�Quote command-line arguments for DOS/Windows conventions.
