This module was deprecated in IPython 7.0, in favour of inputtransformer2. The first class in this module, :class:`InputSplitter`, is designed to tell when input from a line-oriented frontend is complete and should be executed, and when the user should be prompted for another line of code instead. The name 'input splitter' is largely for historical reasons. A companion, :class:`IPythonInputSplitter`, provides the same functionality but with full support for the extended IPython syntax (magics, system calls, etc). The code to actually do these transformations is in :mod:`IPython.core.inputtransformer`. :class:`IPythonInputSplitter` feeds the raw code to the transformers in order and stores the results. For more details, see the class docstrings below. )warnzeIPython.core.inputsplitter is deprecated since IPython 7 in favor of `IPython.core.inputtransformer2`N)List) leading_indentclassic_prompt ipy_prompt cellmagicassemble_logical_lineshelp_endescaped_commandsassign_from_magicassign_from_systemassemble_python_lines) ESC_SHELL ESC_SH_CAPESC_HELP ESC_HELP2 ESC_MAGIC ESC_MAGIC2 ESC_QUOTE ESC_QUOTE2 ESC_PAREN ESC_SEQUENCES|)z^\s+raise(\s.*)?$z^\s+raise\([^\)]*\).*$z^\s+return(\s.*)?$z^\s+return\([^\)]*\).*$z ^\s+pass\s*$z ^\s+break\s*$z^\s+continue\s*$z^([ \t\r\f\v]+)z^\s*\#cft|}|r|SdS)a Return the number of initial spaces in a string.

This object is designed to be fed python source line-by-line, using :meth:`push`. It will return on each push whether the currently pushed code could be executed already. In addition, it provides a method called :meth:`push_accepts_more` that can be used to query whether more input can be pushed into a single interactive block. This is a simple example of how an interactive terminal-based client can use this tool:: isp = InputSplitter() while isp.push_accepts_more(): indent = ' '*isp.indent_spaces prompt = '>>> ' + indent line = indent + raw_input(prompt) isp.push(line) print 'Input source was:\n', isp.source_reset(), NNr8N_buffer_compileFrbcjg|_tj|_t |_dS)z$Create a new InputSplitter instance.N)rcodeopCommandCompilerrrrr+s r r,zInputSplitter.__init__Ls* .00 *,, r"cVg|jdd<d|_d|_d|_d|_dSz,Reset the input buffer and associated state.Nr8F)rsourcert _is_complete _is_invalidrs r resetzInputSplitter.resetRs5 QQQ  ! r"c<|j}||S)z:Return the input source and perform a full reset. )rrr+outs r source_resetzInputSplitter.source_resetZsk  r"c| |||jr |dS|r*d|f|S |dS#t $rY|dSwxYw#|wxYw)akReturn whether a block of code is ready to execute, or should be continued This is a non-stateful API, and will reset the state of this InputSplitter.

Returns ------- is_complete : boolean True if the current input source (the result of the current input plus prior inputs) forms a complete Python execution block. Note that this value is also stored as a private attribute (``_is_complete``), so it can be queried at any time. rFz\ errorexec)symbolNT) isinstancestr_storerrtrrendswithwarningscatch_warnings simplefilter SyntaxWarningrr OverflowError ValueError TypeError MemoryError)r+rLrs r rzInputSplitter.pushsm,%%%%%% E (2$ 4$  ??6 " " 5 6(** A A%g}=== MM&M@@  A A A A A A A A A A A A A A A!%  5D  ]J ], $ $ $ $D #D    $  s6"C57B8, C8B<<C?B<C7D  D c|jsdS|jd}|r|rdS|dkrt |jdkrdS t jd|j }t |j dkrt|j ddsdSn#t$rYdSwxYwdS)aReturn whether a block of interactive input can accept more input. This method is meant to be used by line-oriented frontends, who need to guess whether a block is complete or not based solely on prior and current input lines. The InputSplitter considers it has a complete interactive block and will not accept more input when either: * A SyntaxError is raised * The code is complete and consists of a single line or a single non-compound statement * The code is complete and has a blank line at the end If the current input produces a syntax error, this method immediately returns False but does *not* raise the syntax error exception, as typically clients will want to send invalid syntax to an execution backend which might convert the invalid syntax into valid Python via one of the dynamic IPython mechanisms.
