Shipman (john@nmt.edu), New Mexico Tech Computer Center, Socorro, NM 87801, in March 1997. Freely available under the terms of the GNU General Public License. This class defines methods for the ten standard components of the os.stat() value, giving information about file status. NOTE: The file's information is recorded as of the time the PathInfo object is instantiated. It does not automatically track changes in file size or other attributes. If you want new information, get a new object. Exported methods: ================================================================ PathInfo(pathName) [ if pathname is a valid, existing path name to which this program has directory access -> return a PathInfo representing that path's state else -> raise OSError ] .__str__() [ return a string of the form "m t p" where: m := "drwxrwxrwx" part of `ls -l' t := time as "yyyy-mm-dd hh:mm:ss" p := pathname used to create self ] .path [ self's pathname as a string (read-only, please!) ] .size() [ return self's size as an integer ] .stat [ the file status tuple for self ] .mode [ the mode bits from the file status tuple for self ] .modEpoch [ the file's modification timestamp as an epoch time ] .modTime() [ return self's modification timestamp as a string of the form "YYYY-MM-DD hh:mm:ss" ] .ownerCanRead() [ if owner can read self -> return a nonzero integer else -> return 0 ] .ownerCanWrite() [ if owner can write self -> return a nonzero integer else -> return 0 ] .ownerCanExec() [ if owner can execute self -> return a nonzero integer else -> return 0 ] .groupCanRead() [ if group can read self -> return a nonzero integer else -> return 0 ] .groupCanWrite() [ if group can write self -> return a nonzero integer else -> return 0 ] .groupCanExec() [ if group can execute self -> return a nonzero integer else -> return 0 ] .worldCanRead() [ if world can read self -> return a nonzero integer else -> return 0 ] .worldCanWrite() [ if world can write self -> return a nonzero integer else -> return 0 ] .worldCanExec() [ if world can execute self -> return a nonzero integer else -> return 0 ] .isDir() [ if self is a directory -> return a nonzero integer else -> return 0 ] .isLink() [ if self is a symbolic link -> return a nonzero integer else -> return 0 ] .isFile() [ if self is an ordinary disk file -> return a nonzero integer else -> return 0 ] iÿÿÿÿNtPathInfocBsËeZdZd„Zd„Zd„Zd„Zd„Zd„Zd„Z d„Z d „Z d „Z d „Z d „Zd „Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„ZRS(sZObject to represent a pathname and the information from the associated inode. cCsE||_ti|ƒ|_|iti|_|iti|_dS(s*Constructor for a PathInfo object N(tpathtostlstattstattST_MODEtmodetST_MTIMEtmodEpoch(tselftpathName((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt__init__\s cCs?tii|iƒd}d|iƒ|iƒ|iƒ|fS(Nis%s %s %8d %s(RRtsplitt_PathInfo__modeFlagstmodTimetsize(R tbaseName((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt__str__nscCs|iƒ|iƒS(N(t_PathInfo__dirFlagt_PathInfo__permFlags(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt __modeFlagswscCsPti|iƒodSti|iƒodSti|iƒodSdSdS(sÖ [ if self is a directory -> return "d" else if self is a symbolic link -> return "l" else if self is a regular file -> return "-" else -> return "?" ] tltdt-t?N(RtS_ISLNKRtS_ISDIRtS_ISREG(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt __dirFlag}scCs“|i|iti@|iti@|iti@ƒ|i|iti@|iti@|iti@ƒ|i|iti @|iti @|iti @ƒS(s1Return the `rwxrwxrwx' part of ls output ( t_PathInfo__rwxRRtS_IRUSRtS_IWUSRtS_IXUSRtS_IRGRPtS_IWGRPtS_IXGRPtS_IROTHtS_IWOTHtS_IXOTH(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt __permFlagssa cCs0|i|dƒ|i|dƒ|i|dƒS(sá [ return a string of the form "abc" where: a := "r" if r is nonzero, else "-" b := "w" if w is nonzero, else "-" c := "x" if x is nonzero, else "-" ] trtwtx(t_PathInfo__dasher(R R(R)R*((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt__rwx scCs|o|SdSdS(sS [ if b is true -> return c else -> return "-" ] RN((R tbtc((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt__dasher®scCstidti|iƒƒS(sR [ return self's modification time as "yyyy-dd-mm hh:mm:ss" ] s%Y-%m-%d %H:%M:%S(ttimetstrftimet localtimeR(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyR»s cCs|itiS(N(RtST_SIZE(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyRÅscCs|iti@S(N(RRR(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt ownerCanReadÎscCs|iti@S(N(RRR(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt ownerCanWriteÑscCs|iti@S(N(RRR (R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt ownerCanExecÔscCs|iti@S(N(RRR!(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt groupCanRead×scCs|iti@S(N(RRR"(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt groupCanWriteÚscCs|iti@S(N(RRR#(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt groupCanExecÝscCs|iti@S(N(RRR$(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt worldCanReadàscCs|iti@S(N(RRR%(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt worldCanWriteãscCs|iti@S(N(RRR&(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyt worldCanExecæscCsti|iƒS(N(RRR(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pytisDirîscCsti|iƒS(N(RRR(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pytisLinkñscCsti|iƒS(N(RRR(R ((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pytisFileôs(t__name__t __module__t__doc__R RR RRRR+RRR4R5R6R7R8R9R:R;R<R=R>R?(((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pyRTs,                ((RBRR0RR(((s-/u/www/docs/tcc/projects/pystyler/pathinfo.pytKs
