popen_spawn - use pexpect with a piped subprocess¶
Provides an interface like pexpect.spawn interface using subprocess.Popen
PopenSpawn class¶
- class pexpect.popen_spawn.PopenSpawn(cmd, timeout=30, maxread=2000, searchwindowsize=None, logfile=None, cwd=None, env=None, encoding=None, codec_errors='strict', preexec_fn=None)[source]¶
- __init__(cmd, timeout=30, maxread=2000, searchwindowsize=None, logfile=None, cwd=None, env=None, encoding=None, codec_errors='strict', preexec_fn=None)[source]¶
- Initialize self. See help(type(self)) for accurate signature. 
 - sendline(s='')[source]¶
- Wraps send(), sending string - sto child process, with os.linesep automatically appended. Returns number of bytes written.
 - writelines(sequence)[source]¶
- This calls write() for each element in the sequence. - The sequence can be any iterable object producing strings, typically a list of strings. This does not add line separators. There is no return value. 
 - kill(sig)[source]¶
- Sends a Unix signal to the subprocess. - Use constants from the - signalmodule to specify which signal.
 - expect()¶
- expect_exact()¶
- expect_list()¶
- As - pexpect.spawn.
