11.5.1 The`dircmp` class

dircmp instances are built using this constructor:

class dircmp( a, b[, ignore[, hide]]): Construct a new directory comparison object, to compare thedirectoriesa andb.ignore is a list of names toignore, and defaults to['RCS', 'CVS', 'tags'].hide is alist of names to hide, and defaults to[os.curdir, os.pardir].

Thedircmp class provides the following methods:

report( ): Print (tosys.stdout) a comparison betweena andb.

report_partial_closure( ): Print a comparison betweena andb and common immediatesubdirectories.

report_full_closure( ): Print a comparison betweena andb and common subdirectories (recursively).

Thedircmp offers a number of interesting attributes that maybe used to get various bits of information about the directory treesbeing compared.

Note that via__getattr__() hooks, all attributes arecomputed lazily, so there is no speed penalty if only thoseattributes which are lightweight to compute are used.

left_list: Files and subdirectories ina, filtered byhide andignore.

right_list: Files and subdirectories inb, filtered byhide andignore.

common: Files and subdirectories in botha andb.

left_only: Files and subdirectories only ina.

right_only: Files and subdirectories only inb.

common_dirs: Subdirectories in botha andb.

common_files: Files in botha andb

common_funny: Names in botha andb, such that the type differs betweenthe directories, or names for whichos.stat() reports anerror.

same_files: Files which are identical in botha andb.

diff_files: Files which are in botha andb, whose contents differ.

funny_files: Files which are in botha andb, but could not becompared.

subdirs: A dictionary mapping names incommon_dirs todircmp objects.

Release 2.5.2, documentation updated on 21st February, 2008.
