We define a special input line filter to allow typing lines which begin with '>>> ' or '... '. These two strings, if present at the start of the input line, are stripped. This allows for direct pasting of code from examples such as those available in the standard Python tutorial. Normally pasting such code is one chunk is impossible because of the extraneous >>> and ..., requiring one to do a line by line paste with careful removal of those characters. This module allows pasting that kind of multi-line examples in one pass. Here is an 'screenshot' of a section of the tutorial pasted into IPython with this feature enabled: In [1]: >>> def fib2(n): # return Fibonacci series up to n ...: ... '''Return a list containing the Fibonacci series up to n.''' ...: ... result = [] ...: ... a, b = 0, 1 ...: ... while b < n: ...: ... result.append(b) # see below ...: ... a, b = b, a+b ...: ... return result ...: In [2]: fib2(10) Out[2]: [1, 1, 2, 3, 5, 8] The >>> and ... are stripped from the input so that the python interpreter only sees the real part of the code. All other input is processed normally. Notes ===== * You can even paste code that has extra initial spaces, such as is common in doctests: In [3]: >>> a = ['Mary', 'had', 'a', 'little', 'lamb'] In [4]: >>> for i in range(len(a)): ...: ... print i, a[i] ...: ... 0 Mary 1 had 2 a 3 little 4 lamb (sReleases%s <%s>sFernandoN(sInteractiveShells(^[ \t]*>>> |^[ \t]*\.\.\. )cCs| odSnti|ƒ}|o'|i|t|idƒƒ|ƒSnM|i ƒdjo|id|ƒSn&|i ƒodSn|i||ƒSdS(sFAlternate prefilter for input of pasted code from an interpreter. sis...N( slines PROMPT_REsmatchsmsselfs _prefilterslensgroups continuationsstripsisspace(sselfslines continuationsm((sY/u/d/b/dbachman/=/lib/python2.3/site-packages/IPython/Extensions/InterpreterPasteInput.pysprefilter_pasteZs' cCs tt_dS(s?Rebind the input-pasting filter to be the new IPython prefilterN(sprefilter_pastesInteractiveShells prefilter(((sY/u/d/b/dbachman/=/lib/python2.3/site-packages/IPython/Extensions/InterpreterPasteInput.pysactivate_prefilterpscCstit_dS(sReset the filter.N(sInteractiveShells _prefilters prefilter(((sY/u/d/b/dbachman/=/lib/python2.3/site-packages/IPython/Extensions/InterpreterPasteInput.pysdeactivate_prefiltertss9*** Pasting of code with ">>>" or "..." has been enabled.(s__doc__sIPythonsReleasesauthorss __author__slicenses __license__sres IPython.iplibsInteractiveShellscompiles PROMPT_REsprefilter_pastesactivate_prefiltersdeactivate_prefilter( sdeactivate_prefilters __license__s PROMPT_REsInteractiveShellsactivate_prefilters __author__sresReleasesprefilter_paste((sY/u/d/b/dbachman/=/lib/python2.3/site-packages/IPython/Extensions/InterpreterPasteInput.pys?3s
