test | InteractiveShell.cache_main_mod | Cache a main module's namespace.
When scripts are executed via %run, we must keep a reference to the
namespace of their __main__ module (a FakeModule instance) around so
that Python doesn't clear it, rendering objects defined therein
useless.
This method keeps said reference in a private dict, keyed by the
absolute path of the module object (which corresponds to the script
path). This way, for multiple executions of the same script we only
keep one copy of the namespace (the last one), thus preventing memory
leaks from old references while allowing the objects from the last
execution to be accessible.
Note: we can not allow the actual FakeModule instances to be deleted,
because of how Python tears down modules (it hard-sets all their
references to None without regard for reference counts). This method
must therefore make a *copy* of the given namespace, to allow the
original module's __dict__ to be cleared and reused.
Parameters
----------
ns : a namespace (a dict, typically)
fname : str
Filename associated with the namespace.
Examples
--------

In [11]: _ip.cache_main_mod(IPython.__dict__,IPython.__file__)

test | InteractiveShell.set_custom_exc | set_custom_exc(exc_tuple,handler)
Set a custom exception handler, which will be called if any of the
exceptions in exc_tuple occur in the mainloop (specifically, in the
run_code() method).
Parameters
----------
exc_tuple : tuple of exception classes
A *tuple* of exception classes, for which to call the defined
handler. It is very important that you use a tuple, and NOT A
LIST here, because of the way Python's except statement works. If
you only want to trap a single exception, use a singleton tuple::
exc_tuple == (MyCustomException,)
handler : callable
handler must have the following signature::
def my_handler(self, etype, value, tb, tb_offset=None):
...
return structured_traceback
Your handler must return a structured traceback (a list of strings),
or None.
This will be made into an instance method (via types.MethodType)
of IPython itself, and it will be called if any of the exceptions
listed in the exc_tuple are caught. If the handler is None, an
internal basic one is used, which just prints basic info.
To protect IPython from crashes, if your handler ever raises an
exception or returns an invalid result, it will be immediately
disabled.
WARNING: by putting in your own exception handler into IPython's main
execution loop, you run a very good chance of nasty crashes. This
facility should only be used if you really know what you are doing. | environment/lib/python2.7/site-packages/IPython/core/interactiveshell.py | def set_custom_exc(self, exc_tuple, handler):

test | InteractiveShell.excepthook | One more defense for GUI apps that call sys.excepthook.
GUI frameworks like wxPython trap exceptions and call
sys.excepthook themselves. I guess this is a feature that
enables them to keep running after exceptions that would
otherwise kill their mainloop. This is a bother for IPython
which excepts to catch all of the program exceptions with a try:
except: statement.
Normally, IPython sets sys.excepthook to a CrashHandler instance, so if
any app directly invokes sys.excepthook, it will look to the user like
IPython crashed. In order to work around this, we can disable the
CrashHandler and replace it with this excepthook instead, which prints a
regular traceback using our InteractiveTB. In this fashion, apps which
call sys.excepthook will generate a regular-looking exception from
IPython, and the CrashHandler will only be triggered by real IPython
crashes.
This hook should be used sparingly, only in places which are not likely
to be true IPython errors. | environment/lib/python2.7/site-packages/IPython/core/interactiveshell.py | def excepthook(self, etype, value, tb):

Parameters
----------
text : string
A string of text to be completed on. It can be given as empty and
instead a line/position pair are given. In this case, the
completer itself will split the line like readline does.
line : string, optional
The complete line that text is part of.
cursor_pos : int, optional
The position of the cursor on the input line.
Returns
-------
text : string
The actual text that was completed.
matches : list
A sorted list with all possible completions.
The optional arguments allow the completion to take more context into
account, and are part of the low-level completion API.
This is a wrapper around the completion mechanism, similar to what
readline does at the command line when the TAB key is hit. By
exposing it as a method, it can be used by other non-readline
environments (such as GUIs) for text completion.
Simple usage example:
In [1]: x = 'hello'
In [2]: _ip.complete('x.l')

test | InteractiveShell.magic | DEPRECATED. Use run_line_magic() instead.
Call a magic function by name.
Input: a string containing the name of the magic function to call and
any additional arguments to be passed to the magic.
magic('name -opt foo bar') is equivalent to typing at the ipython
prompt:
In[1]: %name -opt foo bar
To call a magic without arguments, simply use magic('name').

Parameters
----------

true, the raw input history is used instead.

test | skipif | Make function raise SkipTest exception if a given condition is true.
If the condition is a callable, it is used at runtime to dynamically
make the decision. This is useful for tests that may require costly
imports, to delay the cost until the test suite is actually executed.
Parameters
----------
skip_condition : bool or callable
Flag to determine whether to skip the decorated test.
msg : str, optional
Message to give on raising a SkipTest exception. Default is None.
Returns
-------
decorator : function
Decorator which, when applied to a function, causes SkipTest
to be raised when `skip_condition` is True, and the function
to be called normally otherwise.
Notes
-----
The decorator itself is decorated with the ``nose.tools.make_decorator``
function in order to transmit function name, and various other metadata. | environment/lib/python2.7/site-packages/IPython/external/decorators/_decorators.py | def skipif(skip_condition, msg=None):

test | run | This function runs the given command; waits for it to finish; then

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 pseudo ttys. 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 myname@host.example.com:.')
child.expect ('(?i)password')
child.sendline (mypassword)
The previous code can be replace with the following::
from pexpect import *
run ('scp foo myname@host.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)
Tricky Examples
===============
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 a dictionary of patterns and responses.
Whenever one of the patterns is seen in the command out run() will send the
associated response string. Note that you should put newlines in your
string if Enter is necessary. The responses may also contain callback
functions. Any callback is function that takes a dictionary 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. | environment/lib/python2.7/site-packages/IPython/external/pexpect/_pexpect.py | def run (command, timeout=-1, withexitstatus=False, events=None, extra_args=None,

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)
Tricky Examples
===============
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 a dictionary of patterns and responses.
Whenever one of the patterns is seen in the command out run() will send the
associated response string. Note that you should put newlines in your
string if Enter is necessary. The responses may also contain callback
functions. Any callback is function that takes a dictionary 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."""

test | spawnb.expect | 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
After a match is found the instance attributes 'before', 'after' and
'match' will be set. You can see all the data read before the match in
'before'. You can see the data that was matched in 'after'. The
re.MatchObject used in the re match will be in 'match'. If an error
occurred then 'before' will be set to all the data read so far and
'after' and 'match' will be None.
If timeout is -1 then timeout will be set to the self.timeout value.
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
