The file opens at the line where the object definition begins. IPython will honor the environment variable PAGER if set, and otherwise will do its best to print the file in a convenient form. If the given argument is not an object currently defined, IPython will try to interpret it as a filename (automatically adding a .py extension if needed).

Still, the rest of the command line must be unchanged (options come first), so for example the following forms are equivalent %psearch -i a* function -i a* function? ?-i a* function Arguments: PATTERN where PATTERN is a string containing * as a wildcard similar to its use in a shell. The pattern is matched in all namespaces on the search path. By default objects starting with a single _ are not matched, many IPython generated objects have a single underscore. The default is case insensitive matching. Matching is also done on the attributes of objects and not only on the objects in a module. [OBJECT TYPE] Is the name of a python type from the types module. The name is given in lowercase without the ending type, ex. StringType is written string. By adding a type here only objects matching the given type are matched. Using all here makes the pattern match all types (this is the default). Options: -a: makes the pattern match even objects whose names start with a single underscore. These names are normally omitted from the search. -i/-c: make the pattern case insensitive/sensitive. If neither of these options are given, the default is read from your configuration file, with the option ``InteractiveShell.wildcards_case_sensitive``. If this option is not specified in your configuration file, IPython's internal default is to do a case sensitive search. -e/-s NAMESPACE: exclude/search a given namespace. The pattern you specify can be searched in any of the following namespaces: 'builtin', 'user', 'user_global','internal', 'alias', where 'builtin' and 'user' are the search defaults. Note that you should not use quotes when specifying namespaces. -l: List all available object types for object matching. This function can be used without arguments. 'Builtin' contains the python module builtin, 'user' contains all user data, 'alias' only contain the shell aliases and no python objects, 'internal' contains objects used by IPython. The 'user_global' namespace is only used by embedded IPython instances, and it contains module-level globals. You can add namespaces to the search with -s or exclude them with -e (these options can be given more than once). Examples -------- :: %psearch a* -> objects beginning with an a %psearch -e builtin a* -> objects NOT in the builtin space starting in a %psearch a* function -> all functions beginning with an a %psearch re.e* -> objects beginning with an e in module re %psearch r*.e* -> objects that start with e in modules starting in r %psearch r*.* string -> all strings in modules beginning with r Case sensitive search:: %psearch -c a* list all object beginning with lower case a Show objects beginning with a single _:: %psearch -a _* list objects beginning with a single underscore List available objects:: %psearch -l list all available object types )Z user_localZ user_global�builtinzcias:e:lT)Zlist_allF�l�i�c�s�ec s g | ]}|� vr|�qS r r )�.0�nm�Z ns_excluder r � <listcomp>� � z+NamespaceMagics.psearch.<locals>.<listcomp>�a)Zshow_all� ignore_case� list_typesN) � parse_options�getr Z inspectorr Zwildcards_case_sensitive�extendZns_table� showtraceback) r r Z def_search�opts�args�optr r r7 r6 Z ns_searchr r2 r r | s, X � zNamespaceMagics.psearchc s` | j j�| j j�t� � � ��fdd��D �}|�� }|rTt|����fdd�|D �}|�� |S )a� Return a sorted list of all interactive variables. If arguments are given, only variables of types matching these arguments are returned. Examples -------- Define two variables and list them with who_ls:: In [1]: alpha = 123 In [2]: beta = 'test' In [3]: %who_ls Out[3]: ['alpha', 'beta'] In [4]: %who_ls int Out[4]: ['alpha'] In [5]: %who_ls str Out[5]: ['beta'] c s. g | ]&}|� d �s�| ��|� �ur|�qS )�_)� startswithr9 �r0 r, )� nonmatching�user_ns�user_ns_hiddenr r r3 s �z*NamespaceMagics.who_ls.<locals>.<listcomp>c s" g | ]}t �| �j� v r|�qS r )�type�__name__rA )�typesetrC r r r3 r4 )r rC rD �object�split�set�sort)r r r' �typelistr )rB rG rC rD r �who_ls� s zNamespaceMagics.who_lsc C sj | � |�}|s(|r td� ntd� dS d}|D ].}t|d dd� |d7 }|d kr0d}t� q0t� dS ) a� Print all interactive variables, with some minimal formatting. If any arguments are given, only variables whose type matches one of these are printed. For example:: %who function str will only list functions and strings, excluding all other types of variables. To find the proper type names, simply use type(var) at a command line to see how python prints type names. For example: :: In [1]: type('hello')\ Out[1]: <type 'str'> indicates that the type name for strings is 'str'. ``%who`` always excludes executed names loaded through your configuration file and things which are internal to IPython. This is deliberate, as typically you may load many modules and the purpose of %who is to show you only what you've manually defined. Examples -------- Define two variables and list them with who:: In [1]: alpha = 123 In [2]: beta = 'test' In [3]: %who alpha beta In [4]: %who int alpha In [5]: %who str beta �'No variables match your requested type.� Interactive namespace is empty.Nr � � ��endr � )rM r& )r r �varlist�countr, r r r �who s . zNamespaceMagics.whoc s �� |�}|s(|r td� ntd� dS g d�}d}dtjv rhzddlm} W n ty` Y n0 |j}dd i� � fd d �}�fd d �|D �}g }|D ]>} || �} | dkr�|�� � t | j �t | j ��� q�|�| � q�d} d} d} d}d}d}t t t t|��t| ��| }t t t t|��t| ��| }t| �|�| �|� d | d d|| t| � d � d}d}t|||�D �]�\}}}t|j||||d�dd � ||v �r�td t t|�� � �qv||k�rtt |j��d d ��dd �dd!� }||k�r |j}||j }|j}|d"k �r*t|||||f � nHt|||||f dd � ||k �r`td#|| f � ntd$|| f � n�z t |�} W n6 t�y� |�td%�} Y n d&t|� } Y n0 | �dd'�} t| �d(k �r�t| � n t| dd)� d* | d+d� � �qvdS ),a% Like %who, but gives some extra information about each variable. The same type filtering of %who can be applied here. For all variables, the type is printed. Additionally it prints: - For {},[],(): their length. - For numpy arrays, a summary with shape, number of elements, typecode and size in memory. - Everything else: a string representation, snipping their middle if too long.

Parameters ---------- -f force reset without asking for confirmation. -s 'Soft' reset: Only clears your namespace, leaving history intact. References to objects may be kept. By default (without this option), we do a 'hard' reset, giving you a new session and removing all references to objects from the current session. --aggressive Try to aggressively remove modules from sys.modules ; this may allow you to reimport Python modules that have been updated and pick up changes, but can have unintended consequences. in reset input history out reset output history dhist reset directory history array reset only variables that are NumPy arrays See Also -------- reset_selective : invoked as ``%reset_selective`` Examples -------- :: In [6]: a = 1 In [7]: a Out[7]: 1 In [8]: 'a' in get_ipython().user_ns Out[8]: True In [9]: %reset -f In [1]: 'a' in get_ipython().user_ns Out[1]: False In [2]: %reset -f in Flushing input history In [3]: %reset -f dhist in Flushing directory history Flushing input history Notes ----- Calling this magic from clients that do not implement standard input, such as the ipython notebook interface, will reset the namespace without confirmation.
