Merging Fernando's trunk (fp-trunk-dev) and Brian's edits (fp-review).

This is a huge merge of months worth of work by Fernando and Brian.

Some highlights:

* The test suite has been ported to use the new APIs.
* The test suite runs and passes on all platforms!!!
* The IPython Sphinx directive has been updated to use the new APIs.
* %history works again.
* New %tb magic for showing last traceback.
* Significant design improvements in the config loaders and applications.
* Zillions of bugs fixed.
* Completely new %pylab implementation that uses the new GUI support.
  This allows pylab to be enabled *at runtime*.
* Many other things.

+"""Experimental code for cleaner support of IPython syntax with unittest.
+
+In IPython up until 0.10, we've used very hacked up nose machinery for running
+tests with IPython special syntax, and this has proved to be extremely slow.
+This module provides decorators to try a different approach, stemming from a
+conversation Brian and I (FP) had about this problem Sept/09.
+
+The goal is to be able to easily write simple functions that can be seen by
+unittest as tests, and ultimately for these to support doctests with full
+IPython syntax.  Nose already offers this based on naming conventions and our
+hackish plugins, but we are seeking to move away from nose dependencies if
+possible.
+
+This module follows a different approach, based on decorators.
+
+- A decorator called @ipdoctest can mark any function as having a docstring

+These are decorators that allow standalone functions and docstrings to be seen

+IPython-syntax docstrings can be auto-converted to '>>>' so that ipython
+sessions can be copy-pasted as tests.
+
+This file can be run as a script, and it will call unittest.main().  We must
+check that it works with unittest as well as with nose...
+
+
+Notes:
+
+- Using nosetests --with-doctest --doctest-tests testfile.py
+  will find docstrings as tests wherever they are, even in methods.  But
+  if we use ipython syntax in the docstrings, they must be decorated with
+  @ipdocstring.  This is OK for test-only code, but not for user-facing
+  docstrings where we want to keep the ipython syntax.
+
+- Using nosetests --with-doctest file.py
+  also finds doctests if the file name doesn't have 'test' in it, because it is
+  treated like a normal module.  But if nose treats the file like a test file,
+  then for normal classes to be doctested the extra --doctest-tests is
+  necessary.
+
+- running this script with python (it has a __main__ section at the end) misses
+  one docstring test, the one embedded in the Foo object method.  Since our
+  approach relies on using decorators that create standalone TestCase
+  instances, it can only be used for functions, not for methods of objects.

+
+        Examples
+        --------
+        In this case, where the MPL default is TkAgg:
+        In [2]: %pylab
+
+        Welcome to pylab, a matplotlib-based Python environment.
+        Backend in use: TkAgg
+        For more information, type 'help(pylab)'.
+
+        But you can explicitly request a different backend:
+        In [3]: %pylab qt
+
+        Welcome to pylab, a matplotlib-based Python environment.
+        Backend in use: Qt4Agg

+ipython [options] [files]
 
-A Python shell with automatic history (input and output), dynamic object
-introspection, easier configuration, command completion, access to the system
-shell and more.
-
-IPython can also be embedded in running programs. See EMBEDDING below.
-
-
-USAGE
-       ipython [options] files
-
-       If invoked with no options, it executes all the files listed in
-       sequence and drops you into the interpreter while still acknowledging
-       any options you may have set in your ipythonrc file. This behavior is
-       different from standard Python, which when called as python -i will
-       only execute one file and will ignore your configuration setup.
-
-       Please note that some of the configuration options are not available at
-       the command line, simply because they are not practical here. Look into
-       your ipythonrc configuration file for details on those. This file
-       typically installed in the $HOME/.ipython directory.
-
-       For Windows users, $HOME resolves to C:\\Documents and
-       Settings\\YourUserName in most instances, and _ipython is used instead
-       of .ipython, since some Win32 programs have problems with dotted names
-       in directories.
-
-       In the rest of this text, we will refer to this directory as
-       IPYTHON_DIR.
-
-REGULAR OPTIONS
-       After the above threading options have been given, regular options  can
-       follow  in any order.  All options can be abbreviated to their shortest
-       non-ambiguous form and are case-sensitive.  One or two  dashes  can  be
-       used.   Some options have an alternate short form, indicated after a |.
-
-       Most options can also be set from your  ipythonrc  configuration  file.
-       See the provided examples for assistance.  Options given on the comman-
-       dline override the values set in the ipythonrc file.
-
-       All options with a [no] prepended can be specified in negated form
-       (using -nooption instead of -option) to turn the feature off.
-
-       -h, --help
-              Show summary of options.
-
-       -autocall <val>
-              Make IPython automatically call any callable object even if you
-              didn't type explicit parentheses. For example, 'str 43' becomes
-              'str(43)' automatically.  The value can be '0' to disable the
-              feature, '1' for 'smart' autocall, where it is not applied if
-              there are no more arguments on the line, and '2' for 'full'
-              autocall, where all callable objects are automatically called
-              (even if no arguments are present).  The default is '1'.
-
-       -[no]autoindent
-              Turn automatic indentation on/off.
-
-       -[no]automagic
-              Make magic commands automatic (without needing their first char-
-              acter to be %).  Type %magic at  the  IPython  prompt  for  more
-              information.
-
-       -[no]autoedit_syntax
-              When a syntax error occurs after editing a file, automatically
-              open the file to the trouble causing line for convenient fixing.
-
-       -[no]banner
-              Print the intial information banner (default on).
-
-       -c <command>
-              Execute  the  given  command  string, and set sys.argv to ['c'].
-              This is similar to the -c option in  the  normal  Python  inter-
-              preter.
-
-       -cache_size|cs <n>
-              Size  of  the output cache (maximum number of entries to hold in
-              memory).  The default is 1000, you can change it permanently  in
-              your  config  file.   Setting  it  to  0 completely disables the
-              caching system, and the minimum value accepted  is  20  (if  you
-              provide  a value less than 20, it is reset to 0 and a warning is
-              issued).  This limit is defined because otherwise  you'll  spend
-              more time re-flushing a too small cache than working.
-
-       -classic|cl
-              Gives IPython a similar feel to the classic Python prompt.
-
-       -colors <scheme>
-              Color  scheme  for  prompts  and exception reporting.  Currently
-              implemented: NoColor, Linux, and LightBG.
-
-       -[no]color_info
-              IPython can display information about objects via a set of func-
-              tions, and optionally can use colors for this, syntax highlight-
-              ing source code and various other  elements.   However,  because
-              this  information  is  passed  through a pager (like 'less') and
-              many pagers get confused with color codes, this option is off by
-              default.   You  can  test  it and turn it on permanently in your
-              ipythonrc file if it works for you.  As a reference, the  'less'
-              pager  supplied  with  Mandrake 8.2 works ok, but that in RedHat
-              7.2 doesn't.
-
-              Test it and turn it on permanently if it works with your system.
-              The  magic function @color_info allows you to toggle this inter-
-              actively for testing.
-
-       -[no]confirm_exit
-              Set to confirm when you try to exit IPython with  an  EOF  (Con-
-              trol-D in Unix, Control-Z/Enter in Windows). Note that using the
-              magic functions @Exit or @Quit you  can  force  a  direct  exit,
-              bypassing any confirmation.
-
-       -[no]debug
-              Show  information  about the loading process. Very useful to pin
-              down problems with your configuration files or  to  get  details
-              about session restores.
-
-       -[no]deep_reload
-              IPython  can use the deep_reload module which reloads changes in
-              modules recursively (it replaces the reload() function,  so  you
-              don't need to change anything to use it). deep_reload() forces a
-              full reload of modules whose code may have  changed,  which  the
-              default reload() function does not.
-
-              When  deep_reload  is off, IPython will use the normal reload(),
-              but deep_reload will still be available as dreload(). This  fea-
-              ture  is  off  by default [which means that you have both normal
-              reload() and dreload()].
-
-       -editor <name>
-              Which editor to use with the @edit command. By default,  IPython
-              will  honor  your EDITOR environment variable (if not set, vi is
-              the Unix default and notepad the Windows one). Since this editor
-              is  invoked on the fly by IPython and is meant for editing small
-              code snippets, you may want to use a small,  lightweight  editor
-              here (in case your default EDITOR is something like Emacs).
-
-       -ipythondir <name>
-              The  name  of  your  IPython configuration directory IPYTHON_DIR.
-              This can also be  specified  through  the  environment  variable
-              IPYTHON_DIR.
-
-       -log|l Generate  a log file of all input. The file is named
-              ipython_log.py in your current directory (which prevents logs
-              from multiple IPython sessions from trampling each other). You
-              can use this to later restore a session by loading your logfile
-              as a file to be executed with option -logplay (see below).
-
-       -logfile|lf
-              Specify the name of your logfile.
-
-       -logplay|lp
-              Replay  a previous log. For restoring a session as close as pos-
-              sible to the state you left it in, use this option  (don't  just
-              run the logfile). With -logplay, IPython will try to reconstruct
-              the previous working environment in full, not just  execute  the
-              commands in the logfile.
-              When  a  session is restored, logging is automatically turned on
-              again with the name of the logfile it was invoked  with  (it  is
-              read  from the log header). So once you've turned logging on for
-              a session, you can quit IPython and reload it as many  times  as
-              you  want  and  it  will continue to log its history and restore
-              from the beginning every time.
-
-              Caveats: there are limitations in this option. The history vari-
-              ables  _i*,_* and _dh don't get restored properly. In the future
-              we will try to implement full  session  saving  by  writing  and
-              retrieving  a failed because of inherent limitations of Python's
-              Pickle module, so this may have to wait.
-
-       -[no]messages
-              Print messages which IPython collects about its startup  process
-              (default on).
-
-       -[no]pdb
-              Automatically  call the pdb debugger after every uncaught excep-
-              tion. If you are used to debugging  using  pdb,  this  puts  you
-              automatically  inside of it after any call (either in IPython or
-              in code called by it) which triggers  an  exception  which  goes
-              uncaught.
-
-       -[no]pprint
-              IPython  can  optionally  use the pprint (pretty printer) module
-              for displaying results. pprint tends to give a nicer display  of
-              nested  data structures. If you like it, you can turn it on per-
-              manently in your config file (default off).
-
-       -profile|p <name>
-              Assume that your config file is ipythonrc-<name> (looks in  cur-
-              rent dir first, then in IPYTHON_DIR). This is a quick way to keep
-              and load multiple config files for different  tasks,  especially
-              if  you  use  the include option of config files. You can keep a
-              basic IPYTHON_DIR/ipythonrc file and then have  other  'profiles'
-              which  include  this  one  and  load extra things for particular
-              tasks. For example:
-
-              1) $HOME/.ipython/ipythonrc : load basic things you always want.
-              2)  $HOME/.ipython/ipythonrc-math  :  load  (1)  and basic math-
-              related modules.
-              3) $HOME/.ipython/ipythonrc-numeric : load (1) and  Numeric  and
-              plotting modules.
-
-              Since  it is possible to create an endless loop by having circu-
-              lar file inclusions, IPython will stop if it reaches  15  recur-
-              sive inclusions.
-
-       -prompt_in1|pi1 <string>
-              Specify  the string used for input prompts. Note that if you are
-              using numbered prompts, the number is represented with a '\#' in
-              the  string.  Don't forget to quote strings with spaces embedded
-              in them. Default: 'In [\#]: '.
-
-              Most bash-like  escapes  can  be  used  to  customize  IPython's
-              prompts, as well as a few additional ones which are IPython-spe-
-              cific.  All valid prompt escapes are described in detail in  the
-              Customization section of the IPython HTML/PDF manual.
-
-       -prompt_in2|pi2 <string>
-              Similar to the previous option, but used for the continuation
-              prompts. The special sequence '\D' is similar to '\#', but with
-              all digits replaced dots (so you can have your continuation
-              prompt aligned with your input prompt).  Default: ' .\D.: '
-              (note three spaces at the start for alignment with 'In [\#]').
-
-       -prompt_out|po <string>
-              String   used   for  output  prompts,  also  uses  numbers  like
-              prompt_in1.  Default: 'Out[\#]:'.
-
-       -quick Start in bare bones mode (no config file loaded).
-
-       -rcfile <name>
-              Name of your  IPython  resource  configuration  file.   normally
-              IPython    loads   ipythonrc   (from   current   directory)   or
-              IPYTHON_DIR/ipythonrc.  If the loading of your config file fails,
-              IPython  starts  with  a  bare  bones  configuration (no modules
-              loaded at all).
-
-       -[no]readline
-              Use the readline library, which is needed to support  name  com-
-              pletion  and  command history, among other things. It is enabled
-              by default, but may cause  problems  for  users  of  X/Emacs  in
-              Python comint or shell buffers.
-
-              Note  that  emacs 'eterm' buffers (opened with M-x term) support
-              IPython's readline and syntax coloring fine, only  'emacs'  (M-x
-              shell and C-c !)  buffers do not.
-
-       -screen_length|sl <n>
-              Number  of lines of your screen.  This is used to control print-
-              ing of very long strings.  Strings longer than  this  number  of
-              lines  will be sent through a pager instead of directly printed.
-
-              The default value for this is 0, which means IPython will  auto-
-              detect  your  screen  size  every time it needs to print certain
-              potentially long strings (this doesn't change  the  behavior  of
-              the  'print'  keyword,  it's  only triggered internally). If for
-              some reason this isn't working well (it needs  curses  support),
-              specify it yourself. Otherwise don't change the default.
-
-       -separate_in|si <string>
-              Separator before input prompts.  Default '0.
-
-       -separate_out|so <string>
-              Separator before output prompts.  Default: 0 (nothing).
-
-       -separate_out2|so2 <string>
-              Separator after output prompts.  Default: 0 (nothing).
-
-       -nosep Shorthand for '-separate_in 0 -separate_out 0 -separate_out2 0'.
-              Simply removes all input/output separators.
-
-       -upgrade
-              Allows you to upgrade your  IPYTHON_DIR  configuration  when  you
-              install  a  new  version  of  IPython.   Since  new versions may
-              include new command lines options or example files, this  copies
-              updated ipythonrc-type files.  However, it backs up (with a .old
-              extension) all files which it overwrites so that you  can  merge
-              back any custimizations you might have in your personal files.
-
-       -Version
-              Print version information and exit.
-
-       -wxversion <string>
-              Select a specific version of wxPython (used in conjunction with
-              -wthread). Requires the wxversion module, part of recent
-              wxPython distributions.
-
-       -xmode <modename>
-              Mode  for  exception reporting.  The valid modes are Plain, Con-
-              text, and Verbose.
-
-              - Plain: similar to python's normal traceback printing.
-
-              - Context: prints 5 lines of context  source  code  around  each
-              line in the traceback.
-
-              - Verbose: similar to Context, but additionally prints the vari-
-              ables currently visible where the exception happened (shortening
-              their  strings if too long).  This can potentially be very slow,
-              if you happen to have a huge data structure whose string  repre-
-              sentation  is  complex  to compute.  Your computer may appear to
-              freeze for a while with cpu usage at 100%.  If this occurs,  you
-              can cancel the traceback with Ctrl-C (maybe hitting it more than
-              once).
-
-
-EMBEDDING
-       It is possible to start an IPython instance inside your own Python pro-
-       grams.  In the documentation example files there are some illustrations
-       on how to do this.
-
-       This feature allows you to evalutate  dynamically  the  state  of  your
-       code,  operate  with  your  variables, analyze them, etc.  Note however
-       that any changes you make to values while in the shell do NOT propagate
-       back  to  the running code, so it is safe to modify your values because
-       you won't break your code in bizarre ways by doing so.

+IPython: an enhanced interactive Python shell.
+
+    A Python shell with automatic history (input and output), dynamic object
+    introspection, easier configuration, command completion, access to the
+    system shell and more.  IPython can also be embedded in running programs.
 
-cmd_line_usage = __doc__
+    If invoked with no options, it executes all the files listed in sequence
+    and exits, use -i to enter interactive mode after running the files.  Files
+    ending in .py will be treated as normal Python, but files ending in .ipy
+    can contain special IPython syntax (magic commands, shell expansions, etc.)
+
+    Please note that some of the configuration options are not available at the
+    command line, simply because they are not practical here. Look into your
+    ipython_config.py configuration file for details on those.
+
+    This file typically installed in the $HOME/.ipython directory.  For Windows
+    users, $HOME resolves to C:\\Documents and Settings\\YourUserName in most
+    instances.
+
+    In IPython's documentation, we will refer to this directory as IPYTHON_DIR,
+    you can change its default location by setting any path you want in this
+    environment variable.
+
+    For more information, see the manual available in HTML and PDF in your
+    installation, or online at http://ipython.scipy.org.

@@ -10,27 +10,79 b' This module provides a set of useful decorators meant to be ready to use in'
 your own tests.  See the bottom of the file for the ready-made ones, and if you
 find yourself writing a new one that may be of generic use, add it here.
 
+Included decorators:
+
+
+Lightweight testing that remains unittest-compatible.
+
+- @parametric, for parametric test support that is vastly easier to use than
+  nose's for debugging. With ours, if a test fails, the stack under inspection
+  is that of the test and not that of the test framework.
+
+- An @as_unittest decorator can be used to tag any normal parameter-less
+  function as a unittest TestCase.  Then, both nose and normal unittest will
+  recognize it as such.  This will make it easier to migrate away from Nose if
+  we ever need/want to while maintaining very lightweight tests.
+
 NOTE: This file contains IPython-specific decorators and imports the
 numpy.testing.decorators file, which we've copied verbatim.  Any of our own
 code will be added at the bottom if we end up extending this.
