Home-page: http://pexpect.readthedocs.org/ Author: Noah Spurrier; Thomas Kluyver; Jeff Quast Author-email: noah@noah.org; thomas@kluyver.me.uk; contact@jeffquast.com License: ISC license Description: Pexpect is a pure Python module for spawning child applications; controlling them; and responding to expected patterns in their output. Pexpect works like Don Libes' Expect. Pexpect allows your script to spawn a child application and control it as if a human were typing commands. Pexpect can be used for automating interactive applications such as ssh, ftp, passwd, telnet, etc. It can be used to a automate setup scripts for duplicating software package installations on different servers. It can be used for automated software testing. Pexpect is in the spirit of Don Libes' Expect, but Pexpect is pure Python. The main features of Pexpect require the pty module in the Python standard library, which is only available on Unix-like systems. Some features—waiting for patterns from file descriptors or subprocesses—are also available on Windows.

Is there a mailing list?** A: You can use the `pexpect tag on Stackoverflow `__ to ask questions specifically related to Pexpect. For more general Python support, there's the python-list_ mailing list, and the `#python`_ IRC channel. Please refrain from using github for general python or systems scripting support. .. _python-list: https://mail.python.org/mailman/listinfo/python-list .. _#python: https://www.python.org/community/irc/ **Q: Why don't shell pipe and redirect (| and >) work when I spawn a command?** A: Remember that Pexpect does NOT interpret shell meta characters such as redirect, pipe, or wild cards (``>``, ``|``, or ``*``). That's done by a shell not the command you are spawning. This is a common mistake. If you want to run a command and pipe it through another command then you must also start a shell. For example:: child = pexpect.spawn('/bin/bash -c "ls -l | grep LOG > log_list.txt"') child.expect(pexpect.EOF) The second form of spawn (where you pass a list of arguments) is useful in situations where you wish to spawn a command and pass it its own argument list. This can make syntax more clear. For example, the following is equivalent to the previous example:: shell_cmd = 'ls -l | grep LOG > log_list.txt' child = pexpect.spawn('/bin/bash', ['-c', shell_cmd]) child.expect(pexpect.EOF) **Q: The `before` and `after` properties sound weird.** A: This is how the -B and -A options in grep works, so that made it easier for me to remember. Whatever makes my life easier is what's best. Originally I was going to model Pexpect after Expect, but then I found that I didn't actually like the way Expect did some things. It was more confusing. The `after` property can be a little confusing at first, because it will actually include the matched string. The `after` means after the point of match, not after the matched string. **Q: Why not just use Expect?** A: I love it. It's great. I has bailed me out of some real jams, but I wanted something that would do 90% of what I need from Expect; be 10% of the size; and allow me to write my code in Python instead of TCL. Pexpect is not nearly as big as Expect, but Pexpect does everything I have ever used Expect for. .. _whynotpipe: **Q: Why not just use a pipe (popen())?** A: A pipe works fine for getting the output to non-interactive programs. If you just want to get the output from ls, uname, or ping then this works. Pipes do not work very well for interactive programs and pipes will almost certainly fail for most applications that ask for passwords such as telnet, ftp, or ssh. There are two reasons for this. * First an application may bypass stdout and print directly to its controlling TTY. Something like SSH will do this when it asks you for a password. This is why you cannot redirect the password prompt because it does not go through stdout or stderr. * The second reason is because most applications are built using the C Standard IO Library (anything that uses ``#include ``). One of the features of the stdio library is that it buffers all input and output. Normally output is line buffered when a program is printing to a TTY (your terminal screen). Everytime the program prints a line-feed the currently buffered data will get printed to your screen. The problem comes when you connect a pipe. The stdio library is smart and can tell that it is printing to a pipe instead of a TTY. In that case it switches from line buffer mode to block buffered. In this mode the currently buffered data is flushed when the buffer is full. This causes most interactive programs to deadlock. Block buffering is more efficient when writing to disks and pipes. Take the situation where a program prints a message ``"Enter your user name:\n"`` and then waits for you type type something. In block buffered mode, the stdio library will not put the message into the pipe even though a linefeed is printed. The result is that you never receive the message, yet the child application will sit and wait for you to type a response. Don't confuse the stdio lib's buffer with the pipe's buffer. The pipe buffer is another area that can cause problems. You could flush the input side of a pipe, whereas you have no control over the stdio library buffer. More information: the Standard IO library has three states for a ``FILE *``. These are: _IOFBF for block buffered; _IOLBF for line buffered; and _IONBF for unbuffered. The STDIO lib will use block buffering when talking to a block file descriptor such as a pipe. This is usually not helpful for interactive programs. Short of recompiling your program to include fflush() everywhere or recompiling a custom stdio library there is not much a controlling application can do about this if talking over a pipe. The program may have put data in its output that remains unflushed because the output buffer is not full; then the program will go and deadlock while waiting for input -- because you never send it any because you are still waiting for its output (still stuck in the STDIO's output buffer). The answer is to use a pseudo-tty. A TTY device will force line buffering (as opposed to block buffering). Line buffering means that you will get each line when the child program sends a line feed. This corresponds to the way most interactive programs operate -- send a line of output then wait for a line of input. I put "answer" in quotes because it's ugly solution and because there is no POSIX standard for pseudo-TTY devices (even though they have a TTY standard...). What would make more sense to me would be to have some way to set a mode on a file descriptor so that it will tell the STDIO to be line-buffered. I have investigated, and I don't think there is a way to set the buffered state of a child process. The STDIO Library does not maintain any external state in the kernel or whatnot, so I don't think there is any way for you to alter it. I'm not quite sure how this line-buffered/block-buffered state change happens internally in the STDIO library. I think the STDIO lib looks at the file descriptor and decides to change behavior based on whether it's a TTY or a block file (see isatty()). I hope that this qualifies as helpful. Don't use a pipe to control another application. **Q: Can I do screen scraping with this thing?** A: That depends. If your application just does line-oriented output then this is easy. If a program emits many terminal sequences, from video attributes to screen addressing, such as programs using curses, then it may become very difficult to ascertain what text is displayed on a screen. We suggest using the `pyte `_ library to screen-scrape. The module :mod:`pexpect.ANSI` released with previous versions of pexpect is now marked deprecated and may be removed in the future. **Q: I get strange behavior with pexect and gevent** A: Pexpect uses fork(2), exec(2), select(2), waitpid(2), and implements its own selector in expect family of calls. pexpect has been known to misbehave when paired with gevent. A solution might be to isolate your pexpect dependent code from any frameworks that manipulate event selection behavior by running it in an another process entirely. pexpect-4.0.1/doc/Makefile000066400000000000000000000127001261544427200154000ustar00rootroot00000000000000# Makefile for Sphinx documentation # # You can set these variables from the command line.

If you pass the *encoding* parameter to the constructor, it will instead act as a unicode interface: strings you send will be encoded using that encoding, and bytes received will be decoded before returning them to you. In this mode, patterns for :meth:`~spawn.expect` and :meth:`~spawn.expect_exact` should also be unicode. .. versionchanged:: 4.0 :class:`spawn` provides both the bytes and unicode interfaces. In Pexpect 3.x, the unicode interface was provided by a separate ``spawnu`` class. For backwards compatibility, some Unicode is allowed in bytes mode: the send methods will encode arbitrary unicode as UTF-8 before sending it to the child process, and its expect methods can accept ascii-only unicode strings. .. note:: Unicode handling with pexpect works the same way on Python 2 and 3, despite the difference in names. I.e.: - Bytes mode works with ``str`` on Python 2, and :class:`bytes` on Python 3, - Unicode mode works with ``unicode`` on Python 2, and :class:`str` on Python 3. run function ------------ .. autofunction:: run Exceptions ---------- .. autoclass:: EOF .. autoclass:: TIMEOUT .. autoclass:: ExceptionPexpect Utility functions ----------------- .. autofunction:: which .. autofunction:: split_command_line pexpect-4.0.1/doc/api/popen_spawn.rst000066400000000000000000000010151261544427200175710ustar00rootroot00000000000000popen_spawn - use pexpect with a piped subprocess ================================================= .. automodule:: pexpect.popen_spawn PopenSpawn class ---------------- .. autoclass:: PopenSpawn .. automethod:: __init__ .. automethod:: send .. automethod:: sendline .. automethod:: write .. automethod:: writelines .. automethod:: kill .. automethod:: sendeof .. automethod:: wait .. method:: expect expect_exact expect_list As :class:`pexpect.spawn`. pexpect-4.0.1/doc/api/pxssh.rst000066400000000000000000000016641261544427200164170ustar00rootroot00000000000000pxssh - control an SSH session ============================== .. automodule:: pexpect.pxssh .. autoclass:: ExceptionPxssh pxssh class ----------- .. autoclass:: pxssh .. automethod:: __init__ .. attribute:: PROMPT The regex pattern to search for to find the prompt.

The child is successfully spawned but you can't interact with it. The only way to make it work is to spawn and interact with the child all in the same thread. [Adam Kerrison] Timing issue with send() and sendline() --------------------------------------- This problem has been addressed and should not affect most users. It is sometimes possible to read an echo of the string sent with :meth:`~pexpect.spawn.send` and :meth:`~pexpect.spawn.sendline`. If you call :meth:`~pexpect.spawn.send` and then immediately call :meth:`~pexpect.spawn.readline`, you may get part of your output echoed back. You may read back what you just wrote even if the child application does not explicitly echo it. Timing is critical. This could be a security issue when talking to an application that asks for a password; otherwise, this does not seem like a big deal. But why do TTYs do this? People usually report this when they are trying to control SSH or some other login. For example, if your code looks something like this:: child.expect ('[pP]assword:') child.sendline (my_password) 1. SSH prints "password:" prompt to the user. 2. SSH turns off echo on the TTY device. 3. SSH waits for user to enter a password. When scripting with Pexpect what can happen is that Pexpect will respond to the "password:" prompt before SSH has had time to turn off TTY echo. In other words, Pexpect sends the password between steps 1. and 2., so the password gets echoed back to the TTY. I would call this an SSH bug. Pexpect now automatically adds a short delay before sending data to a child process. This more closely mimics what happens in the usual human-to-app interaction. The delay can be tuned with the ``delaybeforesend`` attribute of the spawn class. In general, this fixes the problem for everyone and so this should not be an issue for most users. For some applications you might with to turn it off:: child = pexpect.spawn ("ssh user@example.com") child.delaybeforesend = 0 Truncated output just before child exits ---------------------------------------- So far I have seen this only on older versions of Apple's MacOS X. If the child application quits it may not flush its output buffer. This means that your Pexpect application will receive an EOF even though it should have received a little more data before the child died. This is not generally a problem when talking to interactive child applications. One example where it is a problem is when trying to read output from a program like *ls*. You may receive most of the directory listing, but the last few lines will get lost before you receive an EOF. The reason for this is that *ls* runs; completes its task; and then exits. The buffer is not flushed before exit so the last few lines are lost. The following example demonstrates the problem:: child = pexpect.spawn('ls -l') child.expect(pexpect.EOF) print child.before Controlling SSH on Solaris -------------------------- Pexpect does not yet work perfectly on Solaris. One common problem is that SSH sometimes will not allow TTY password authentication. For example, you may expect SSH to ask you for a password using code like this:: child = pexpect.spawn('ssh user@example.com') child.expect('password') child.sendline('mypassword') You may see the following error come back from a spawned child SSH:: Permission denied (publickey,keyboard-interactive). This means that SSH thinks it can't access the TTY to ask you for your password. The only solution I have found is to use public key authentication with SSH. This bypasses the need for a password. I'm not happy with this solution. The problem is due to poor support for Solaris Pseudo TTYs in the Python Standard Library. child does not receive full input, emits BEL -------------------------------------------- You may notice when running for example cat(1) or base64(1), when sending a very long input line, that it is not fully received, and the BEL ('\a') may be found in output. By default the child terminal matches the parent, which is often in "canonical mode processing". You may wish to disable this mode. The exact limit of a line varies by operating system, and details of disabling canonical mode may be found in the docstring of :meth:`~pexpect.spawn.send`. pexpect-4.0.1/doc/conf.py000066400000000000000000000177111261544427200152460ustar00rootroot00000000000000# -*- coding: utf-8 -*- # # Pexpect documentation build configuration file, created by # sphinx-quickstart on Tue Sep 17 11:05:11 2013. # # This file is execfile()d with the current directory set to its containing dir. # # Note that not all possible configuration values are present in this # autogenerated file. # # All configuration values have a default; values that are commented out # serve to show the default. import sys, os # If extensions (or modules to document with autodoc) are in another directory, # add these directories to sys.path here.

This is the best way to learn to use Pexpect. See the descriptions of Pexpect Examples. `topip.py `_ This runs `netstat` on a local or remote server. It calculates some simple statistical information on the number of external inet connections. This can be used to detect if one IP address is taking up an excessive number of connections. It can also send an email alert if a given IP address exceeds a threshold between runs of the script. This script can be used as a drop-in Munin plugin or it can be used stand-alone from cron. I used this on a busy web server that would sometimes get hit with denial of service attacks. This made it easy to see if a script was opening many multiple connections. A typical browser would open fewer than 10 connections at once. A script might open over 100 simultaneous connections. `hive.py `_ This script creates SSH connections to a list of hosts that you provide. Then you are given a command line prompt. Each shell command that you enter is sent to all the hosts. The response from each host is collected and printed. For example, you could connect to a dozen different machines and reboot them all at once. `script.py `_ This implements a command similar to the classic BSD "script" command. This will start a subshell and log all input and output to a file. This demonstrates the :meth:`~pexpect.spawn.interact` method of Pexpect. `ftp.py `_ This demonstrates an FTP "bookmark". This connects to an ftp site; does a few ftp tasks; and then gives the user interactive control over the session. In this case the "bookmark" is to a directory on the OpenBSD ftp server. It puts you in the i386 packages directory. You can easily modify this for other sites. This demonstrates the :meth:`~pexpect.spawn.interact` method of Pexpect. `monitor.py `_ This runs a sequence of commands on a remote host using SSH. It runs a simple system checks such as uptime and free to monitor the state of the remote host. `passmass.py `_ This will login to each given server and change the password of the given user. This demonstrates scripting logins and passwords. `python.py `_ This starts the python interpreter and prints the greeting message backwards. It then gives the user iteractive control of Python. It's pretty useless! `ssh_tunnel.py `_ This starts an SSH tunnel to a remote machine. It monitors the connection and restarts the tunnel if it goes down. `uptime.py `_ This will run the uptime command and parse the output into variables. This demonstrates using a single regular expression to match the output of a command and capturing different variable in match groups. The grouping regular expression handles a wide variety of different uptime formats. pexpect-4.0.1/doc/history.rst000066400000000000000000000274051261544427200162030ustar00rootroot00000000000000History ======= Releases -------- Version 4.0 ``````````` * Integration with :mod:`asyncio`: passing ``async=True`` to :meth:`~.spawn.expect`, :meth:`~.spawn.expect_exact` or :meth:`~.spawn.expect_list` will make them return a coroutine. You can get the result using ``yield from``, or wrap it in an :class:`asyncio.Task`. This allows the event loop to do other things while waiting for output that matches a pattern. * Experimental support for Windows (with some caveats)—see :ref:`windows`. * Enhancement: allow method as callbacks of argument ``events`` for :func:`pexpect.run` (:ghissue:`176`). * It is now possible to call :meth:`~.spawn.wait` multiple times, or after a process is already determined to be terminated without raising an exception (:ghpull:`211`). * New :class:`pexpect.spawn` keyword argument, ``dimensions=(rows, columns)`` allows setting terminal screen dimensions before launching a program (:ghissue:`122`). * Fix regression that prevented executable, but unreadable files from being found when not specified by absolute path -- such as /usr/bin/sudo (:ghissue:`104`). * Fixed regression when executing pexpect with some prior releases of the multiprocessing module where stdin has been closed (:ghissue:`86`). Backwards incompatible changes ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ * Deprecated ``pexpect.screen`` and ``pexpect.ANSI``. Please use other packages such as `pyte `__ to emulate a terminal. * Removed the independent top-level modules (``pxssh fdpexpect FSM screen ANSI``) which were installed alongside Pexpect. These were moved into the Pexpect package in 3.0, but the old names were left as aliases. * Child processes created by Pexpect no longer ignore SIGHUP by default: the ``ignore_sighup`` parameter of :class:`pexpect.spawn` defaults to False. To get the old behaviour, pass ``ignore_sighup=True``. Version 3.3 ``````````` * Added a mechanism to wrap REPLs, or shells, in an object which can conveniently be used to send commands and wait for the output (:mod:`pexpect.replwrap`). * Fixed issue where pexpect would attempt to execute a directory because it has the 'execute' bit set (:ghissue:`37`). * Removed the ``pexpect.psh`` module. This was never documented, and we found no evidence that people use it. The new :mod:`pexpect.replwrap` module provides a more flexible alternative. * Fixed ``TypeError: got ('\r\n') as pattern`` in :meth:`spawnu.readline` method (:ghissue:`67`). * Fixed issue where EOF was not correctly detected in :meth:`~.interact`, causing a repeating loop of output on Linux, and blocking before EOF on BSD and Solaris (:ghissue:`49`). * Several Solaris (SmartOS) bugfixes, preventing :exc:`IOError` exceptions, especially when used with cron(1) (:ghissue:`44`). * Added new keyword argument ``echo=True`` for :class:`spawn`. On SVR4-like systems, the method :meth:`~.isatty` will always return *False*: the child pty does not appear as a terminal. Therefore, :meth:`~.setecho`, :meth:`~.getwinsize`, :meth:`~.setwinsize`, and :meth:`~.waitnoecho` are not supported on those platforms. After this, we intend to start working on a bigger refactoring of the code, to be released as Pexpect 4. There may be more bugfix 3.x releases, however. Version 3.2 ``````````` * Fix exception handling from :func:`select.select` on Python 2 (:ghpull:`38`). This was accidentally broken in the previous release when it was fixed for Python 3. * Removed a workaround for ``TIOCSWINSZ`` on very old systems, which was causing issues on some BSD systems (:ghpull:`40`). * Fixed an issue with exception handling in :mod:`~pexpect.pxssh` (:ghpull:`43`) The documentation for :mod:`~pexpect.pxssh` was improved. Version 3.1 ``````````` * Fix an issue that prevented importing pexpect on Python 3 when ``sys.stdout`` was reassigned (:ghissue:`30`). * Improve prompt synchronisation in :mod:`~pexpect.pxssh` (:ghpull:`28`). * Fix pickling exception instances (:ghpull:`34`). * Fix handling exceptions from :func:`select.select` on Python 3 (:ghpull:`33`). The examples have also been cleaned up somewhat - this will continue in future releases. Version 3.0 ``````````` The new major version number doesn't indicate any deliberate API incompatibility. We have endeavoured to avoid breaking existing APIs. However, pexpect is under new maintenance after a long dormancy, so some caution is warranted. * A new :ref:`unicode API ` was introduced. * Python 3 is now supported, using a single codebase. * Pexpect now requires at least Python 2.6 or 3.2. * The modules other than pexpect, such as :mod:`pexpect.fdpexpect` and :mod:`pexpect.pxssh`, were moved into the pexpect package. For now, wrapper modules are installed to the old locations for backwards compatibility (e.g. ``import pxssh`` will still work), but these will be removed at some point in the future. * Ignoring ``SIGHUP`` is now optional - thanks to Kimmo Parviainen-Jalanko for the patch. We also now have `docs on ReadTheDocs `_, and `continuous integration on Travis CI `_. Version 2.4 ``````````` * Fix a bug regarding making the pty the controlling terminal when the process spawning it is not, actually, a terminal (such as from cron) Version 2.3 ``````````` * Fixed OSError exception when a pexpect object is cleaned up. Previously, you might have seen this exception:: Exception exceptions.OSError: (10, 'No child processes') in > ignored You should not see that anymore. Thanks to Michael Surette. * Added support for buffering reads. This greatly improves speed when trying to match long output from a child process. When you create an instance of the spawn object you can then set a buffer size. For now you MUST do the following to turn on buffering -- it may be on by default in future version:: child = pexpect.spawn ('my_command') child.maxread=1000 # Sets buffer to 1000 characters. * I made a subtle change to the way TIMEOUT and EOF exceptions behave. Previously you could either expect these states in which case pexpect will not raise an exception, or you could just let pexpect raise an exception when these states were encountered. If you expected the states then the ``before`` property was set to everything before the state was encountered, but if you let pexpect raise the exception then ``before`` was not set. Now, the ``before`` property will get set either way you choose to handle these states. * The spawn object now provides iterators for a *file-like interface*. This makes Pexpect a more complete file-like object. You can now write code like this:: child = pexpect.spawn ('ls -l') for line in child: print line * write and writelines() no longer return a value. Use send() if you need that functionality. I did this to make the Spawn object more closely match a file-like object. * Added the attribute ``exitstatus``. This will give the exit code returned by the child process. This will be set to ``None`` while the child is still alive. When ``isalive()`` returns 0 then ``exitstatus`` will be set. * Made a few more tweaks to ``isalive()`` so that it will operate more consistently on different platforms. Solaris is the most difficult to support. * You can now put ``TIMEOUT`` in a list of expected patterns. This is just like putting ``EOF`` in the pattern list. Expecting for a ``TIMEOUT`` may not be used as often as ``EOF``, but this makes Pexpect more consistent. * Thanks to a suggestion and sample code from Chad J. Schroeder I added the ability for Pexpect to operate on a file descriptor that is already open. This means that Pexpect can be used to control streams such as those from serial port devices. Now, you just pass the integer file descriptor as the "command" when constructing a spawn open. For example on a Linux box with a modem on ttyS1:: fd = os.open("/dev/ttyS1", os.O_RDWR|os.O_NONBLOCK|os.O_NOCTTY) m = pexpect.spawn(fd) # Note integer fd is used instead of usual string. m.send("+++") # Escape sequence m.send("ATZ0\r") # Reset modem to profile 0 rval = m.expect(["OK", "ERROR"]) * ``read()`` was renamed to ``read_nonblocking()``. Added new ``read()`` method that matches file-like object interface. In general, you should not notice the difference except that ``read()`` no longer allows you to directly set the timeout value. I hope this will not effect any existing code. Switching to ``read_nonblocking()`` should fix existing code. * Changed the name of ``set_echo()`` to ``setecho()``. * Changed the name of ``send_eof()`` to ``sendeof()``. * Modified ``kill()`` so that it checks to make sure the pid ``isalive()``. * modified ``spawn()`` (really called from ``__spawn()``) so that it does not raise an expection if ``setwinsize()`` fails. Some platforms such as Cygwin do not like setwinsize. This was a constant problem and since it is not a critical feature I decided to just silence the error. Normally I don't like to do that, but in this case I'm making an exception. * Added a method ``close()`` that does what you think. It closes the file descriptor of the child application. It makes no attempt to actually kill the child or wait for its status. * Add variables ``__version__`` and ``__revision__`` (from cvs) to the pexpect modules. This is mainly helpful to me so that I can make sure that I'm testing with the right version instead of one already installed. * ``log_open()`` and ``log_close(`` have been removed. Now use ``setlog()``. The ``setlog()`` method takes a file object. This is far more flexible than the previous log method. Each time data is written to the file object it will be flushed. To turn logging off simply call ``setlog()`` with None. * renamed the ``isAlive()`` method to ``isalive()`` to match the more typical naming style in Python. Also the technique used to detect child process status has been drastically modified. Previously I did some funky stuff with signals which caused indigestion in other Python modules on some platforms. It was a big headache. It still is, but I think it works better now. * attribute ``matched`` renamed to ``after`` * new attribute ``match`` * The ``expect_eof()`` method is gone. You can now simply use the ``expect()`` method to look for EOF. * **Pexpect works on OS X**, but the nature of the quirks cause many of the tests to fail. See bugs. (Incomplete Child Output). The problem is more than minor, but Pexpect is still more than useful for most tasks. * **Solaris**: For some reason, the *second* time a pty file descriptor is created and deleted it never gets returned for use. It does not effect the first time or the third time or any time after that. It's only the second time. This is weird... This could be a file descriptor leak, or it could be some peculiarity of how Solaris recycles them. I thought it was a UNIX requirement for the OS to give you the lowest available filedescriptor number. In any case, this should not be a problem unless you create hundreds of pexpect instances... It may also be a pty module bug. Moves and forks --------------- * Pexpect development used to be hosted on Sourceforge. * In 2011, Thomas Kluyver forked pexpect as 'pexpect-u', to support Python 3. He later decided he had taken the wrong approach with this. * In 2012, Noah Spurrier, the original author of Pexpect, moved the project to Github, but was still too busy to develop it much. * In 2013, Thomas Kluyver and Jeff Quast forked Pexpect again, intending to call the new fork Pexpected. Noah Spurrier agreed to let them use the name Pexpect, so Pexpect versions 3 and above are based on this fork, which now lives `here on Github `_. pexpect-4.0.1/doc/index.rst000066400000000000000000000027751261544427200156140ustar00rootroot00000000000000Pexpect version |version| ========================= .. image:: https://travis-ci.org/pexpect/pexpect.png?branch=master :target: https://travis-ci.org/pexpect/pexpect :align: right :alt: Build status Pexpect makes Python a better tool for controlling other applications. Pexpect is a pure Python module for spawning child applications; controlling them; and responding to expected patterns in their output. Pexpect works like Don Libes' Expect. Pexpect allows your script to spawn a child application and control it as if a human were typing commands. Pexpect can be used for automating interactive applications such as ssh, ftp, passwd, telnet, etc. It can be used to a automate setup scripts for duplicating software package installations on different servers. It can be used for automated software testing. Pexpect is in the spirit of Don Libes' Expect, but Pexpect is pure Python. Unlike other Expect-like modules for Python, Pexpect does not require TCL or Expect nor does it require C extensions to be compiled. It should work on any platform that supports the standard Python pty module. The Pexpect interface was designed to be easy to use.

Here is an example of Pexpect in action:: # This connects to the openbsd ftp site and # downloads the recursive directory listing. import pexpect child = pexpect.spawn('ftp ftp.openbsd.org') child.expect('Name .*: ') child.sendline('anonymous') child.expect('Password:') child.sendline('noah@example.com') child.expect('ftp> ') child.sendline('lcd /tmp') child.expect('ftp> ') child.sendline('cd pub/OpenBSD') child.expect('ftp> ') child.sendline('get README') child.expect('ftp> ') child.sendline('bye') Obviously you could write an ftp client using Python's own :mod:`ftplib` module, but this is just a demonstration. You can use this technique with any application. This is especially handy if you are writing automated test tools. There are two important methods in Pexpect -- :meth:`~pexpect.spawn.expect` and :meth:`~pexpect.spawn.send` (or :meth:`~pexpect.spawn.sendline` which is like :meth:`~pexpect.spawn.send` with a linefeed). The :meth:`~pexpect.spawn.expect` method waits for the child application to return a given string. The string you specify is a regular expression, so you can match complicated patterns. The :meth:`~pexpect.spawn.send` method writes a string to the child application. From the child's point of view it looks just like someone typed the text from a terminal. After each call to :meth:`~pexpect.spawn.expect` the ``before`` and ``after`` properties will be set to the text printed by child application. The ``before`` property will contain all text up to the expected string pattern. The ``after`` string will contain the text that was matched by the expected pattern. The match property is set to the `re match object `_. An example of Pexpect in action may make things more clear. This example uses ftp to login to the OpenBSD site; list files in a directory; and then pass interactive control of the ftp session to the human user:: import pexpect child = pexpect.spawn ('ftp ftp.openbsd.org') child.expect ('Name .*: ') child.sendline ('anonymous') child.expect ('Password:') child.sendline ('noah@example.com') child.expect ('ftp> ') child.sendline ('ls /pub/OpenBSD/') child.expect ('ftp> ') print child.before # Print the result of the ls command. child.interact() # Give control of the child to the user. Special EOF and TIMEOUT patterns -------------------------------- There are two special patterns to match the End Of File (:class:`~pexpect.EOF`) or a Timeout condition (:class:`~pexpect.TIMEOUT`). You can pass these patterns to :meth:`~pexpect.spawn.expect`. These patterns are not regular expressions. Use them like predefined constants. If the child has died and you have read all the child's output then ordinarily :meth:`~pexpect.spawn.expect` will raise an :class:`~pexpect.EOF` exception. You can read everything up to the EOF without generating an exception by using the EOF pattern expect. In this case everything the child has output will be available in the ``before`` property. The pattern given to :meth:`~pexpect.spawn.expect` may be a regular expression or it may also be a list of regular expressions. This allows you to match multiple optional responses. The :meth:`~pexpect.spawn.expect` method returns the index of the pattern that was matched. For example, say you wanted to login to a server. After entering a password you could get various responses from the server -- your password could be rejected; or you could be allowed in and asked for your terminal type; or you could be let right in and given a command prompt. The following code fragment gives an example of this:: child.expect('password:') child.sendline(my_secret_password) # We expect any of these three patterns... i = child.expect (['Permission denied', 'Terminal type', '[#\$] ']) if i==0: print('Permission denied on host. Can\'t login') child.kill(0) elif i==1: print('Login OK... need to send terminal type.') child.sendline('vt100') child.expect('[#\$] ') elif i==2: print('Login OK.') print('Shell command prompt', child.after) If nothing matches an expected pattern then :meth:`~pexpect.spawn.expect` will eventually raise a :class:`~pexpect.TIMEOUT` exception. The default time is 30 seconds, but you can change this by passing a timeout argument to :meth:`~pexpect.spawn.expect`:: # Wait no more than 2 minutes (120 seconds) for password prompt. child.expect('password:', timeout=120) Find the end of line -- CR/LF conventions ----------------------------------------- Pexpect matches regular expressions a little differently than what you might be used to. The :regexp:`$` pattern for end of line match is useless. The :regexp:`$` matches the end of string, but Pexpect reads from the child one character at a time, so each character looks like the end of a line. Pexpect can't do a look-ahead into the child's output stream. In general you would have this situation when using regular expressions with any stream. .. note:: Pexpect does have an internal buffer, so reads are faster than one character at a time, but from the user's perspective the regex patterns test happens one character at a time. The best way to match the end of a line is to look for the newline: ``"\r\n"`` (CR/LF). Yes, that does appear to be DOS-style. It may surprise some UNIX people to learn that terminal TTY device drivers (dumb, vt100, ANSI, xterm, etc.) all use the CR/LF combination to signify the end of line. Pexpect uses a Pseudo-TTY device to talk to the child application, so when the child app prints ``"\n"`` you actually see ``"\r\n"``. UNIX uses just linefeeds to end lines of text, but not when it comes to TTY devices! TTY devices are more like the Windows world. Each line of text ends with a CR/LF combination. When you intercept data from a UNIX command from a TTY device you will find that the TTY device outputs a CR/LF combination. A UNIX command may only write a linefeed (``\n``), but the TTY device driver converts it to CR/LF. This means that your terminal will see lines end with CR/LF (hex ``0D 0A``). Since Pexpect emulates a terminal, to match ends of lines you have to expect the CR/LF combination:: child.expect('\r\n') If you just need to skip past a new line then ``expect('\n')`` by itself will work, but if you are expecting a specific pattern before the end of line then you need to explicitly look for the ``\r``. For example the following expects a word at the end of a line:: child.expect('\w+\r\n') But the following would both fail:: child.expect('\w+\n') And as explained before, trying to use :regexp:`$` to match the end of line would not work either:: child.expect ('\w+$') So if you need to explicitly look for the END OF LINE, you want to look for the CR/LF combination -- not just the LF and not the $ pattern. This problem is not limited to Pexpect. This problem happens any time you try to perform a regular expression match on a stream. Regular expressions need to look ahead. With a stream it is hard to look ahead because the process generating the stream may not be finished. There is no way to know if the process has paused momentarily or is finished and waiting for you. Pexpect must implicitly always do a NON greedy match (minimal) at the end of a input. Pexpect compiles all regular expressions with the :data:`re.DOTALL` flag. With the :data:`~re.DOTALL` flag, a ``"."`` will match a newline. Beware of + and * at the end of patterns ---------------------------------------- Remember that any time you try to match a pattern that needs look-ahead that you will always get a minimal match (non greedy). For example, the following will always return just one character:: child.expect ('.+') This example will match successfully, but will always return no characters:: child.expect ('.*') Generally any star * expression will match as little as possible. One thing you can do is to try to force a non-ambiguous character at the end of your :regexp:`\\d+` pattern. Expect that character to delimit the string. For example, you might try making the end of your pattern be :regexp:`\\D+` instead of :regexp:`\\D*`. Number digits alone would not satisfy the :regexp:`(\\d+)\\D+` pattern. You would need some numbers and at least one non-number at the end. Debugging --------- If you get the string value of a :class:`pexpect.spawn` object you will get lots of useful debugging information. For debugging it's very useful to use the following pattern:: try: i = child.expect ([pattern1, pattern2, pattern3, etc]) except: print("Exception was thrown") print("debug information:") print(str(child)) It is also useful to log the child's input and out to a file or the screen. The following will turn on logging and send output to stdout (the screen):: child = pexpect.spawn(foo) child.logfile = sys.stdout Exceptions ---------- :class:`~pexpect.EOF` Note that two flavors of EOF Exception may be thrown. They are virtually identical except for the message string. For practical purposes you should have no need to distinguish between them, but they do give a little extra information about what type of platform you are running. The two messages are: - "End Of File (EOF) in read(). Exception style platform." - "End Of File (EOF) in read(). Empty string style platform." Some UNIX platforms will throw an exception when you try to read from a file descriptor in the EOF state. Other UNIX platforms instead quietly return an empty string to indicate that the EOF state has been reached. If you wish to read up to the end of the child's output without generating an :class:`~pexpect.EOF` exception then use the ``expect(pexpect.EOF)`` method. :class:`~pexpect.TIMEOUT` The :meth:`~pexpect.spawn.expect` and :meth:`~pexpect.spawn.read` methods will also timeout if the child does not generate any output for a given amount of time. If this happens they will raise a :class:`~pexpect.TIMEOUT` exception. You can have these methods ignore timeout and block indefinitely by passing ``None`` for the timeout parameter:: child.expect(pexpect.EOF, timeout=None) .. _windows: Pexpect on Windows ------------------ .. versionadded:: 4.0 Windows support Pexpect can be used on Windows to wait for a pattern to be produced by a child process, using :class:`pexpect.popen_spawn.PopenSpawn`, or a file descriptor, using :class:`pexpect.fdpexpect.fdspawn`. This should be considered experimental for now. :class:`pexpect.spawn` and :func:`pexpect.run` are *not* available on Windows, as they rely on Unix pseudoterminals (ptys). Cross platform code must not use these. pexpect-4.0.1/doc/requirements.txt000066400000000000000000000000131261544427200172160ustar00rootroot00000000000000ptyprocess pexpect-4.0.1/doc/sphinxext/000077500000000000000000000000001261544427200157725ustar00rootroot00000000000000pexpect-4.0.1/doc/sphinxext/github.py000066400000000000000000000124031261544427200176260ustar00rootroot00000000000000"""Define text roles for GitHub * ghissue - Issue * ghpull - Pull Request * ghuser - User Adapted from bitbucket example here: https://bitbucket.org/birkenfeld/sphinx-contrib/src/tip/bitbucket/sphinxcontrib/bitbucket.py Authors ------- * Doug Hellmann * Min RK """ # # Original Copyright (c) 2010 Doug Hellmann.

Then you are given a command line prompt. Each shell command that you enter is sent to all the hosts. The response from each host is collected and printed. For example, you could connect to a dozen different machines and reboot them all at once. script.py This implements a command similar to the classic BSD "script" command. This will start a subshell and log all input and output to a file. This demonstrates the interact() method of Pexpect. fix_cvs_files.py This is for cleaning up binary files improperly added to CVS. This script scans the given path to find binary files; checks with CVS to see if the sticky options are set to -kb; finally if sticky options are not -kb then uses 'cvs admin' to set the -kb option. ftp.py This demonstrates an FTP "bookmark". This connects to an ftp site; does a few ftp commands; and then gives the user interactive control over the session. In this case the "bookmark" is to a directory on the OpenBSD ftp server. It puts you in the i386 packages directory. You can easily modify this for other sites. This demonstrates the interact() method of Pexpect. monitor.py This runs a sequence of system status commands on a remote host using SSH. It runs a simple system checks such as uptime and free to monitor the state of the remote host. passmass.py This will login to a list of hosts and change the password of the given user. This demonstrates scripting logins; although, you could more easily do this using the pxssh subclass of Pexpect. See also the "hive.py" example script for a more general example of scripting a collection of servers. python.py This starts the python interpreter and prints the greeting message backwards. It then gives the user interactive control of Python. It's pretty useless! rippy.py This is a wizard for mencoder. It greatly simplifies the process of ripping a DVD to mpeg4 format (XviD, DivX). It can transcode from any video file to another. It has options for resampling the audio stream; removing interlace artifacts, fitting to a target file size, etc. There are lots of options, but the process is simple and easy to use. sshls.py This lists a directory on a remote machine. ssh_tunnel.py This starts an SSH tunnel to a remote machine. It monitors the connection and restarts the tunnel if it goes down. uptime.py This will run the uptime command and parse the output into python variables. This demonstrates using a single regular expression to match the output of a command and capturing different variable in match groups. The regular expression takes into account a wide variety of different formats for uptime output. df.py This collects filesystem capacity info using the 'df' command. Tuples of filesystem name and percentage are stored in a list. A simple report is printed. Filesystems over 95% capacity are highlighted.

Each command you enter is sent to each host in parallel. The response of each host is collected and printed. In normal synchronous mode Hive will wait for each host to return the shell command line prompt. The shell prompt is used to sync output. Example: $ hive.py --sameuser --samepass host1.example.com host2.example.net username: myusername password: connecting to host1.example.com - OK connecting to host2.example.net - OK targetting hosts: 192.168.1.104 192.168.1.107 CMD (? for help) > uptime ======================================================================= host1.example.com ----------------------------------------------------------------------- uptime 23:49:55 up 74 days, 5:14, 2 users, load average: 0.15, 0.05, 0.01 ======================================================================= host2.example.net ----------------------------------------------------------------------- uptime 23:53:02 up 1 day, 13:36, 2 users, load average: 0.50, 0.40, 0.46 ======================================================================= Other Usage Examples: 1. You will be asked for your username and password for each host. hive.py host1 host2 host3 ... hostN 2. You will be asked once for your username and password. This will be used for each host. hive.py --sameuser --samepass host1 host2 host3 ... hostN 3. Give a username and password on the command-line: hive.py user1:pass2@host1 user2:pass2@host2 ... userN:passN@hostN You can use an extended host notation to specify username, password, and host instead of entering auth information interactively. Where you would enter a host name use this format: username:password@host This assumes that ':' is not part of the password. If your password contains a ':' then you can use '\\:' to indicate a ':' and '\\\\' to indicate a single '\\'. Remember that this information will appear in the process listing. Anyone on your machine can see this auth information. This is not secure. This is a crude script that begs to be multithreaded. But it serves its purpose.

This is similar to :target, but sends only one command and does not change the list of targets for future commands. :sync set mode to wait for shell prompts after commands are run. This is the default. When Hive first logs into a host it sets a special shell prompt pattern that it can later look for to synchronize output of the hosts. If you 'su' to another user then it can upset the synchronization. If you need to run something like 'su' then use the following pattern: CMD (? for help) > :async CMD (? for help) > sudo su - root CMD (? for help) > :prompt CMD (? for help) > :sync :async set mode to not expect command line prompts (see :sync). Afterwards commands are send to target hosts, but their responses are not read back until :sync is run. This is useful to run before commands that will not return with the special shell prompt pattern that Hive uses to synchronize. :refresh refresh the display. This shows the last few lines of output from all hosts. This is similar to resync, but does not expect the promt. This is useful for seeing what hosts are doing during long running commands. :resync This is similar to :sync, but it does not change the mode. It looks for the prompt and thus consumes all input from all targetted hosts. :prompt force each host to reset command line prompt to the special pattern used to synchronize all the hosts. This is useful if you 'su' to a different user where Hive would not know the prompt to match. :send my text This will send the 'my text' wihtout a line feed to the targetted hosts. This output of the hosts is not automatically synchronized. :control X This will send the given control character to the targetted hosts. For example, ":control c" will send ASCII 3. :exit This will exit the hive shell.

If the SSH process ever dies then this script will detect that and restart it. I use this under Cygwin to keep open encrypted tunnels to port 25 (SMTP), port 143 (IMAP4), and port 110 (POP3). I set my mail client to talk to localhost and I keep this script running in the background. Note that this is a rather stupid script at the moment because it just looks to see if any ssh process is running. It should really make sure that our specific ssh process is running. The problem is that ssh is missing a very useful feature. It has no way to report the process id of the background daemon that it creates with the -f command. This would be a really useful script if I could figure a way around this problem.

It calculates some simple statistical information on the number of external inet connections. It groups by IP address. This can be used to detect if one IP address is taking up an excessive number of connections. It can also send an email alert if a given IP address exceeds a threshold between runs of the script. This script can be used as a drop-in Munin plugin or it can be used stand-alone from cron. I used this on a busy web server that would sometimes get hit with denial of service attacks. This made it easy to see if a script was opening many multiple connections. A typical browser would open fewer than 10 connections at once. A script might open over 100 simultaneous connections. ./topip.py [-s server_hostname] [-u username] [-p password] {-a from_addr,to_addr} {-n N} {-v} {--ipv6} -s : hostname of the remote server to login to. -u : username to user for login. -p : password to user for login. -n : print stddev for the the number of the top 'N' ipaddresses. -v : verbose - print stats and list of top ipaddresses. -a : send alert if stddev goes over 20. -l : to log message to /var/log/topip.log --ipv6 : this parses netstat output that includes ipv6 format. Note that this actually only works with ipv4 addresses, but for versions of netstat that print in ipv6 format. --stdev=N : Where N is an integer. This sets the trigger point for alerts and logs. Default is to trigger if the max value is over 5 standard deviations. Example: This will print stats for the top IP addresses connected to the given host: ./topip.py -s www.example.com -u mylogin -p mypassword -n 10 -v This will send an alert email if the maxip goes over the stddev trigger value and the the current top ip is the same as the last top ip (/tmp/topip.last): ./topip.py -s www.example.com -u mylogin -p mypassword \\ -n 10 -v -a alert@example.com,user@example.com This will print the connection stats for the localhost in Munin format: ./topip.py PEXPECT LICENSE This license is approved by the OSI and FSF as GPL-compatible. http://opensource.org/licenses/isc-license.txt Copyright (c) 2012, Noah Spurrier PERMISSION TO USE, COPY, MODIFY, AND/OR DISTRIBUTE THIS SOFTWARE FOR ANY PURPOSE WITH OR WITHOUT FEE IS HEREBY GRANTED, PROVIDED THAT THE ABOVE COPYRIGHT NOTICE AND THIS PERMISSION NOTICE APPEAR IN ALL COPIES.

In addition to state this FSM also maintains a user defined "memory". So this FSM can be used as a Push-down Automata (PDA) since a PDA is a FSM + memory. The following describes how the FSM works, but you will probably also need to see the example function to understand how the FSM is used in practice. You define an FSM by building tables of transitions. For a given input symbol the process() method uses these tables to decide what action to call and what the next state will be. The FSM has a table of transitions that associate: (input_symbol, current_state) --> (action, next_state) Where "action" is a function you define. The symbols and states can be any objects. You use the add_transition() and add_transition_list() methods to add to the transition table. The FSM also has a table of transitions that associate: (current_state) --> (action, next_state) You use the add_transition_any() method to add to this transition table. The FSM also has one default transition that is not associated with any specific input_symbol or state. You use the set_default_transition() method to set the default transition. When an action function is called it is passed a reference to the FSM. The action function may then access attributes of the FSM such as input_symbol, current_state, or "memory". The "memory" attribute can be any object that you want to pass along to the action functions. It is not used by the FSM itself. For parsing you would typically pass a list to be used as a stack. The processing sequence is as follows. The process() method is given an input_symbol to process. The FSM will search the table of transitions that associate: (input_symbol, current_state) --> (action, next_state) If the pair (input_symbol, current_state) is found then process() will call the associated action function and then set the current state to the next_state. If the FSM cannot find a match for (input_symbol, current_state) it will then search the table of transitions that associate: (current_state) --> (action, next_state) If the current_state is found then the process() method will call the associated action function and then set the current state to the next_state. Notice that this table lacks an input_symbol. It lets you define transitions for a current_state and ANY input_symbol. Hence, it is called the "any" table. Remember, it is always checked after first searching the table for a specific (input_symbol, current_state). For the case where the FSM did not match either of the previous two cases the FSM will try to use the default transition. If the default transition is defined then the process() method will call the associated action function and then set the current state to the next_state. This lets you define a default transition as a catch-all case. You can think of it as an exception handler. There can be only one default transition. Finally, if none of the previous cases are defined for an input_symbol and current_state then the FSM will raise an exception. This may be desirable, but you can always prevent this just by defining a default transition.

Pexpect can be used for automating interactive applications such as ssh, ftp, passwd, telnet, etc. It can be used to a automate setup scripts for duplicating software package installations on different servers. It can be used for automated software testing. Pexpect is in the spirit of Don Libes' Expect, but Pexpect is pure Python. Other Expect-like modules for Python require TCL and Expect or require C extensions to be compiled. Pexpect does not use C, Expect, or TCL extensions. It should work on any platform that supports the standard Python pty module. The Pexpect interface focuses on ease of use so that simple tasks are easy. There are two main interfaces to the Pexpect system; these are the function, run() and the class, spawn. The spawn class is more powerful. The run() function is simpler than spawn, and is good for quickly calling program. When you call the run() function it executes a given program and then returns the output. This is a handy replacement for os.system(). For example:: pexpect.run('ls -la') The spawn class is the more powerful interface to the Pexpect system. You can use this to spawn a child program then interact with it by sending input and expecting responses (waiting for patterns in the child's output). For example:: child = pexpect.spawn('scp foo user@example.com:.') child.expect('Password:') child.sendline(mypassword) This works even for commands that ask for passwords or other input outside of the normal stdio streams. For example, ssh reads input directly from the TTY device which bypasses stdin.

The command parameter may be a string that includes a command and any arguments to the command. For example:: child = pexpect.spawn('/usr/bin/ftp') child = pexpect.spawn('/usr/bin/ssh user@example.com') child = pexpect.spawn('ls -latr /tmp') You may also construct it with a list of arguments like so:: child = pexpect.spawn('/usr/bin/ftp', []) child = pexpect.spawn('/usr/bin/ssh', ['user@example.com']) child = pexpect.spawn('ls', ['-latr', '/tmp']) After this the child application will be created and will be ready to talk to. For normal use, see expect() and send() and sendline(). Remember that Pexpect does NOT interpret shell meta characters such as redirect, pipe, or wild cards (``>``, ``|``, or ``*``). This is a common mistake. If you want to run a command and pipe it through another command then you must also start a shell. For example:: child = pexpect.spawn('/bin/bash -c "ls -l | grep LOG > logs.txt"') child.expect(pexpect.EOF) The second form of spawn (where you pass a list of arguments) is useful in situations where you wish to spawn a command and pass it its own argument list. This can make syntax more clear. For example, the following is equivalent to the previous example:: shell_cmd = 'ls -l | grep LOG > logs.txt' child = pexpect.spawn('/bin/bash', ['-c', shell_cmd]) child.expect(pexpect.EOF) The maxread attribute sets the read buffer size. This is maximum number of bytes that Pexpect will try to read from a TTY at one time. Setting the maxread size to 1 will turn off buffering. Setting the maxread value higher may help performance in cases where large amounts of output are read back from the child. This feature is useful in conjunction with searchwindowsize. When the keyword argument *searchwindowsize* is None (default), the full buffer is searched at each iteration of receiving incoming data. The default number of bytes scanned at each iteration is very large and may be reduced to collaterally reduce search cost. After :meth:`~.expect` returns, the full buffer attribute remains up to size *maxread* irrespective of *searchwindowsize* value. When the keyword argument ``timeout`` is specified as a number, (default: *30*), then :class:`TIMEOUT` will be raised after the value specified has elapsed, in seconds, for any of the :meth:`~.expect` family of method calls. When None, TIMEOUT will not be raised, and :meth:`~.expect` may block indefinitely until match. The logfile member turns on or off logging. All input and output will be copied to the given file object. Set logfile to None to stop logging. This is the default. Set logfile to sys.stdout to echo everything to standard output. The logfile is flushed after each write. Example log input and output to a file:: child = pexpect.spawn('some_command') fout = open('mylog.txt','wb') child.logfile = fout Example log to stdout:: # In Python 2: child = pexpect.spawn('some_command') child.logfile = sys.stdout # In Python 3, spawnu should be used to give str to stdout: child = pexpect.spawnu('some_command') child.logfile = sys.stdout The logfile_read and logfile_send members can be used to separately log the input from the child and output sent to the child. Sometimes you don't want to see everything you write to the child. You only want to log what the child sends back. For example:: child = pexpect.spawn('some_command') child.logfile_read = sys.stdout You will need to pass an encoding to spawn in the above code if you are using Python 3. To separately log output sent to the child use logfile_send:: child.logfile_send = fout If ``ignore_sighup`` is True, the child process will ignore SIGHUP signals. The default is False from Pexpect 4.0, meaning that SIGHUP will be handled normally by the child. The delaybeforesend helps overcome a weird behavior that many users were experiencing. The typical problem was that a user would expect() a "Password:" prompt and then immediately call sendline() to send the password. The user would then see that their password was echoed back to them. Passwords don't normally echo. The problem is caused by the fact that most applications print out the "Password" prompt and then turn off stdin echo, but if you send your password before the application turned off echo, then you get your password echoed. Normally this wouldn't be a problem when interacting with a human at a real keyboard. If you introduce a slight delay just before writing then this seems to clear up the problem. This was such a common problem for many users that I decided that the default pexpect behavior should be to sleep just before writing to the child application. 1/20th of a second (50 ms) seems to be enough to clear up the problem. You can set delaybeforesend to 0 to return to the old behavior. Most Linux machines don't like this to be below 0.03. I don't know why. Note that spawn is clever about finding commands on your path. It uses the same logic that "which" uses to find executables. If you wish to get the exit status of the child you must call the close() method. The exit or signal status of the child will be stored in self.exitstatus or self.signalstatus. If the child exited normally then exitstatus will store the exit return code and signalstatus will be None. If the child was terminated abnormally with a signal then signalstatus will store the signal value and exitstatus will be None. If you need more detail you can also read the self.status member which stores the status returned by os.waitpid. You can interpret this using os.WIFEXITED/os.WEXITSTATUS or os.WIFSIGNALED/os.TERMSIG. The echo attribute may be set to False to disable echoing of input. As a pseudo-terminal, all input echoed by the "keyboard" (send() or sendline()) will be repeated to output. For many cases, it is not desirable to have echo enabled, and it may be later disabled using setecho(False) followed by waitnoecho(). However, for some platforms such as Solaris, this is not possible, and should be disabled immediately on spawn. If preexec_fn is given, it will be called in the child process before launching the given command. This is useful to e.g. reset inherited signal handlers. The dimensions attribute specifies the size of the pseudo-terminal as seen by the subprocess, and is specified as a two-entry tuple (rows, columns). If this is unspecified, the defaults in ptyprocess will apply.

''' class pxssh (spawn): '''This class extends pexpect.spawn to specialize setting up SSH connections. This adds methods for login, logout, and expecting the shell prompt. It does various tricky things to handle many situations in the SSH login process. For example, if the session is your first login, then pxssh automatically accepts the remote certificate; or if you have public key authentication setup then pxssh won't wait for the password prompt. pxssh uses the shell prompt to synchronize output from the remote host. In order to make this more robust it sets the shell prompt to something more unique than just $ or #. This should work on most Borne/Bash or Csh style shells. Example that runs a few commands on a remote server and prints the result:: import pxssh import getpass try: s = pxssh.pxssh() hostname = raw_input('hostname: ') username = raw_input('username: ') password = getpass.getpass('password: ') s.login(hostname, username, password) s.sendline('uptime') # run a command s.prompt() # match the prompt print(s.before) # print everything before the prompt. s.sendline('ls -l') s.prompt() print(s.before) s.sendline('df') s.prompt() print(s.before) s.logout() except pxssh.ExceptionPxssh as e: print("pxssh failed on login.") print(e) Example showing how to specify SSH options:: import pxssh s = pxssh.pxssh(options={ "StrictHostKeyChecking": "no", "UserKnownHostsFile": "/dev/null"}) ... Note that if you have ssh-agent running while doing development with pxssh then this can lead to a lot of confusion. Many X display managers (xdm, gdm, kdm, etc.) will automatically start a GUI agent. You may see a GUI dialog box popup asking for a password during development. You should turn off any key agents during testing. The 'force_password' attribute will turn off public key authentication. This will only work if the remote SSH server is configured to allow password logins. Example of using 'force_password' attribute:: s = pxssh.pxssh() s.force_password = True hostname = raw_input('hostname: ') username = raw_input('username: ') password = getpass.getpass('password: ') s.login (hostname, username, password) ''' def __init__ (self, timeout=30, maxread=2000, searchwindowsize=None, logfile=None, cwd=None, env=None, ignore_sighup=True, echo=True, options={}, encoding=None, codec_errors='strict'): spawn.__init__(self, None, timeout=timeout, maxread=maxread, searchwindowsize=searchwindowsize, logfile=logfile, cwd=cwd, env=env, ignore_sighup=ignore_sighup, echo=echo, encoding=encoding, codec_errors=codec_errors) self.name = '' #SUBTLE HACK ALERT!

STDERR is included in output. If the full path to the command is not given then the path is searched. Note that lines are terminated by CR/LF (\\r\\n) combination even on UNIX-like systems because this is the standard for pseudottys. If you set 'withexitstatus' to true, then run will return a tuple of (command_output, exitstatus). If 'withexitstatus' is false then this returns just command_output. The run() function can often be used instead of creating a spawn instance. For example, the following code uses spawn:: from pexpect import * child = spawn('scp foo user@example.com:.') child.expect('(?i)password') child.sendline(mypassword) The previous code can be replace with the following:: from pexpect import * run('scp foo user@example.com:.', events={'(?i)password': mypassword}) **Examples** Start the apache daemon on the local machine:: from pexpect import * run("/usr/local/apache/bin/apachectl start") Check in a file using SVN:: from pexpect import * run("svn ci -m 'automatic commit' my_file.py") Run a command and capture exit status:: from pexpect import * (command_output, exitstatus) = run('ls -l /bin', withexitstatus=1) The following will run SSH and execute 'ls -l' on the remote machine. The password 'secret' will be sent if the '(?i)password' pattern is ever seen:: run("ssh username@machine.example.com 'ls -l'", events={'(?i)password':'secret\\n'}) This will start mencoder to rip a video from DVD. This will also display progress ticks every 5 seconds as it runs. For example:: from pexpect import * def print_ticks(d): print d['event_count'], run("mencoder dvd://1 -o video.avi -oac copy -ovc copy", events={TIMEOUT:print_ticks}, timeout=5) The 'events' argument should be either a dictionary or a tuple list that contains patterns and responses. Whenever one of the patterns is seen in the command output, run() will send the associated response string. So, run() in the above example can be also written as: run("mencoder dvd://1 -o video.avi -oac copy -ovc copy", events=[(TIMEOUT,print_ticks)], timeout=5) Use a tuple list for events if the command output requires a delicate control over what pattern should be matched, since the tuple list is passed to pexpect() as its pattern list, with the order of patterns preserved. Note that you should put newlines in your string if Enter is necessary. Like the example above, the responses may also contain a callback, either a function or method. It should accept a dictionary value as an argument. The dictionary contains all the locals from the run() function, so you can access the child spawn object or any other variable defined in run() (event_count, child, and extra_args are the most useful). A callback may return True to stop the current run process. Otherwise run() continues until the next event. A callback may also return a string which will be sent to the child. 'extra_args' is not used by directly run(). It provides a way to pass data to a callback function through run() through the locals dictionary passed to a callback. Like :class:`spawn`, passing *encoding* will make it work with unicode instead of bytes. You can pass *codec_errors* to control how errors in encoding and decoding are handled.

''' if patterns is None: return [] if not isinstance(patterns, list): patterns = [patterns] # Allow dot to match \n compile_flags = re.DOTALL if self.ignorecase: compile_flags = compile_flags | re.IGNORECASE compiled_pattern_list = [] for idx, p in enumerate(patterns): if isinstance(p, self.allowed_string_types): p = self._coerce_expect_string(p) compiled_pattern_list.append(re.compile(p, compile_flags)) elif p is EOF: compiled_pattern_list.append(EOF) elif p is TIMEOUT: compiled_pattern_list.append(TIMEOUT) elif isinstance(p, type(re.compile(''))): compiled_pattern_list.append(p) else: self._pattern_type_err(p) return compiled_pattern_list def expect(self, pattern, timeout=-1, searchwindowsize=-1, async=False): '''This seeks through the stream until a pattern is matched. The pattern is overloaded and may take several types. The pattern can be a StringType, EOF, a compiled re, or a list of any of those types. Strings will be compiled to re types. This returns the index into the pattern list. If the pattern was not a list this returns index 0 on a successful match. This may raise exceptions for EOF or TIMEOUT. To avoid the EOF or TIMEOUT exceptions add EOF or TIMEOUT to the pattern list. That will cause expect to match an EOF or TIMEOUT condition instead of raising an exception. If you pass a list of patterns and more than one matches, the first match in the stream is chosen. If more than one pattern matches at that point, the leftmost in the pattern list is chosen. For example:: # the input is 'foobar' index = p.expect(['bar', 'foo', 'foobar']) # returns 1('foo') even though 'foobar' is a "better" match Please note, however, that buffering can affect this behavior, since input arrives in unpredictable chunks. For example:: # the input is 'foobar' index = p.expect(['foobar', 'foo']) # returns 0('foobar') if all input is available at once, # but returs 1('foo') if parts of the final 'bar' arrive late When a match is found for the given pattern, the class instance attribute *match* becomes an re.MatchObject result. Should an EOF or TIMEOUT pattern match, then the match attribute will be an instance of that exception class. The pairing before and after class instance attributes are views of the data preceding and following the matching pattern. On general exception, class attribute *before* is all data received up to the exception, while *match* and *after* attributes are value None. When the keyword argument timeout is -1 (default), then TIMEOUT will raise after the default value specified by the class timeout attribute. When None, TIMEOUT will not be raised and may block indefinitely until match. When the keyword argument searchwindowsize is -1 (default), then the value specified by the class maxread attribute is used. A list entry may be EOF or TIMEOUT instead of a string. This will catch these exceptions and return the index of the list entry instead of raising the exception. The attribute 'after' will be set to the exception type. The attribute 'match' will be None. This allows you to write code like this:: index = p.expect(['good', 'bad', pexpect.EOF, pexpect.TIMEOUT]) if index == 0: do_something() elif index == 1: do_something_else() elif index == 2: do_some_other_thing() elif index == 3: do_something_completely_different() instead of code like this:: try: index = p.expect(['good', 'bad']) if index == 0: do_something() elif index == 1: do_something_else() except EOF: do_some_other_thing() except TIMEOUT: do_something_completely_different() These two forms are equivalent. It all depends on what you want. You can also just expect the EOF if you are waiting for all output of a child to finish. For example:: p = pexpect.spawn('/bin/ls') p.expect(pexpect.EOF) print p.before If you are trying to optimize for speed then see expect_list(). On Python 3.4, or Python 3.3 with asyncio installed, passing ``async=True`` will make this return an :mod:`asyncio` coroutine, which you can yield from to get the same result that this method would normally give directly. So, inside a coroutine, you can replace this code:: index = p.expect(patterns) With this non-blocking form:: index = yield from p.expect(patterns, async=True) ''' compiled_pattern_list = self.compile_pattern_list(pattern) return self.expect_list(compiled_pattern_list, timeout, searchwindowsize, async) def expect_list(self, pattern_list, timeout=-1, searchwindowsize=-1, async=False): '''This takes a list of compiled regular expressions and returns the index into the pattern_list that matched the child output.

It demonstrates all the visual attributes of the VT100 terminal. The top line is double-width/single-height with inverse-video line-drawing characters. The 2nd and 3rd lines are double-width/double-height in bold inverse video. They also show the limited scrolling region. The remaining lines will show NORMAL, BOLD, BLINK, INVERSE, and all 16 combinations of those 4 attributes. They show that there is a difference between an underscore character and the underline attribute, and that lower-case decenders go below the underline. A window pane is drawn in the lower right to show how the line-drawing set can be used. At the lower left is the character set double-wide/double-high to show the dot-matrix used. Upper-case characters are 8 by 7 in a 10 by 10 character cell, with 1 blank row on top and 2 on the bottom. The underline attribute uses the first bottom blank row, lower-case decenders use both.
