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. + +Noah Spurrier 20020822 + +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 <noah@noah.org> + 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. + THE SOFTWARE IS PROVIDED "AS IS" AND THE AUTHOR DISCLAIMS ALL WARRANTIES + WITH REGARD TO THIS SOFTWARE INCLUDING ALL IMPLIED WARRANTIES OF + MERCHANTABILITY AND FITNESS.

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. + +Credits: Noah Spurrier, Richard Holden, Marco Molteni, Kimberley Burchett, +Robert Stone, Hartmut Goebel, Chad Schroeder, Erick Tryzelaar, Dave Kirby, Ids +vander Molen, George Todd, Noel Taylor, Nicolas D.

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, we'll use the ``encoding`` argument to decode data + # from the subprocess and handle it as unicode: + child = pexpect.spawn('some_command', encoding='utf-8') + 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 None to return to the old behavior. + + 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:: + + child = pexpect.spawn('some_command') + child.close() + print(child.exitstatus, child.signalstatus) + + 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).
