Return value: True if the files are the same, False otherwise.

IGNORE is a list of names to ignore, defaults to ['RCS', 'CVS', 'tags']. HIDE is a list of names to hide, defaults to [os.curdir, os.pardir]. High level usage: x = dircmp(dir1, dir2) x.report() -> prints a report on the differences between dir1 and dir2 or x.report_partial_closure() -> prints report on differences between dir1 and dir2, and reports on common immediate subdirectories. x.report_full_closure() -> like report_partial_closure, but fully recursive. Attributes: left_list, right_list: The files in dir1 and dir2, filtered by hide and ignore. common: a list of names in both dir1 and dir2. left_only, right_only: names only in dir1, dir2. common_dirs: subdirectories in both dir1 and dir2. common_files: files in both dir1 and dir2. common_funny: names in both dir1 and dir2 where the type differs between dir1 and dir2, or the name is not stat-able. same_files: list of identical files. diff_files: list of filenames which differ. funny_files: list of files which could not be compared. subdirs: a dictionary of dircmp objects, keyed by names in common_dirs. cCsq||_||_|djotiti g|_n ||_|djodddg|_ n ||_ dS(NtRCStCVSttags( tatselftlefttbtrightthideRR tcurdirtpardirtignore(R+R*R-R2R/((Rt__init__us     cCsntti|iƒ|i|iƒ|_tti|iƒ|i|iƒ|_ |ii ƒ|i i ƒdS(N( t_filterR tlistdirR+R,R/R2t left_listR.t right_listtsort(R+((Rtphase0s  cCs»ttttii|iƒ|iƒƒ}ttttii|i ƒ|i ƒƒ}t |i t |i|ƒƒ|_t |i t|i|ƒƒ|_t |i t|i|ƒƒ|_dS(N(tdicttiziptimapR tpathtnormcaseR+R6R*R7R-tmapt __getitem__tifilterthas_keytcommont ifilterfalset left_onlyt right_only(R+R*R-((Rtphase1‰s **!!c Cs‰g|_g|_g|_xg|iD]\}tii|i |ƒ}tii|i |ƒ}d}yti|ƒ}Wntij o} d}nXyti|ƒ}Wntij o} d}nX|o‘ti|iƒ}ti|iƒ}||jo|ii|ƒqti|ƒo|ii|ƒqti|ƒo|ii|ƒq|ii|ƒq%|ii|ƒq%WdS(Nii(R+t common_dirst common_filest common_funnyRCtxR R=tjoinR,ta_pathR.tb_pathtokR ta_statterrortwhytb_statRRta_typetb_typetappendtS_ISDIRtS_ISREG( R+RNRORURSRTRPRMRKRR((Rtphase2s6       cCs7t|i|i|iƒ}|\|_|_|_dS(N( RR+R,R.RItxxt same_filest diff_filest funny_files(R+RZ((Rtphase3³scCssh|_xc|iD]X}tii|i|ƒ}tii|i |ƒ}t |||i |i ƒ|i|dG|iG|iGH|io(|iiƒdG|iGdG|iGHn|io(|iiƒdG|iGdG|iGHn|io|iiƒdG|iGHn|io|iiƒdG|iGHn|io|iiƒdG|iGHn|i o|i iƒdG|i GHn|i o|i iƒdG|i GHndS( NtdiffsOnly int:sIdentical files :sDiffering files :sTrouble with common files :sCommon subdirectories :sCommon funny cases :( R+R,R.RER8RFR[R\R]RHRJ(R+((RtreportΖs,              cCs3|iƒx"|iiƒD]}H|iƒqWdS(N(R+RhR_RcRd(R+Rd((Rtreport_partial_closureίs  cCs3|iƒx"|iiƒD]}H|iƒqWdS(N(R+RhR_RcRdtreport_full_closure(R+Rd((RRjεs  R_R[R\R]RHRIRJRCRERFR6R7cCs;||ijo t|‚n|i||ƒt||ƒS(N(tattrR+t methodmaptAttributeErrortgetattr(R+Rk((Rt __getattr__ρs (t__name__t __module__t__doc__RR3R9RGRYR^RbReRhRiRjR:RlRo(((RRSs"    #      c CsŒ|dj otidtƒngggf}xU|D]M}ti i ||ƒ}ti i ||ƒ}|t|||ƒi|ƒq7W|S(s„Compare common files in two directories. a, b -- directory names common -- list of file names found in both directories shallow -- if true, do comparison based solely on stat() information use_statcache -- obsolete argument Returns a tuple of three lists: files that compare equal files that are different filenames that aren't regular files. s$use_statcache argument is deprecatedN(RRRRRtresRCRKR R=RLR*taxR-tbxt_cmpRRV( R*R-RCRRRsRtRKRu((RRχs    !cCs<y|||||ƒƒ SWntij o dSnXdS(Ni(tabsRR*R-tshR RQ(R*R-RxRwR((RRvscCstt|i|ƒƒS(N(tlistRDtskipt __contains__tflist(R|Rz((RR4scCsšdk}dk}|i|iddƒ\}}t|ƒdjo|iddƒ‚nt|d|dƒ}d|jo|i ƒn |i ƒdS( Nitrisneed exactly two argsis-rt(s-rR~( tsystgetopttargvtoptionstargstlent GetoptErrorRRtddRjRh(R†RƒRR€R‚((Rtdemo%s   t__main__(RrR R Rt itertoolsRARDR<R;t__all__RRRRRRRRRwRvR4R‡Rp(RAR RRŠRR‡R;RvR4RDRRRRR R<RR((Rt? s"    *  €
