The reason we don't use inspect.getsource is that it caches the source, whereas we want this to be modified on the fly when the function is modified. Returns ------- func_code: string The function code source_file: string The path to the file in which the function is defined. first_line: int The first line of the code in the source file. Notes ------ This function does a bit more magic than inspect, and is thus more robust. tiis s Nt__code__iÿÿÿÿ(tNoneRt co_filenametostpathtexiststjointinspecttgetsourcelinest startswithtretmatchtgroupstintRtco_firstlinenotlistRtgetblockthasattrtstrt__hash__trepr(tfunct source_filetcodet source_codetline_notsource_file_objt first_linet source_lines((sDlib/python2.7/site-packages/sklearn/externals/joblib/func_inspect.pyt get_func_codes*      "#cCslddl}t|dƒr'|j}nddl}|jj}x&d D]}|j|||ƒƒ}qFW|S( s2Windows cannot encode some characters in filename.iÿÿÿÿNtquotett!t:s\(R&R'R(R)s\(turllibRR%t urllib.parsetparsetreplace(tstringR*R%tchar((sDlib/python2.7/site-packages/sklearn/externals/joblib/func_inspect.pyt_clean_win_charsRs     c CsRt|dƒr|j}nKytj|ƒ}Wn5tk ret|dƒr\|jj}qfd}nX|dkr{d}n|dkr3ytjj tj |ƒƒ}Wn d}nX|dk r3|j tj ƒ}|dj dƒrôd|dCompatibility function to provide inspect.getfullargspec in Python 2 This should be rewritten using a backport of Python 3 signature once we drop support for Python 2.6.
