Module Util

Parameters:

• root - : the root node of the tree
• child_func - : the function called to get the children of a node
• prune - : don't visit the same node twice
• margin - : the format of the left margin to use for children of root. 1 results in a pipe, and 0 results in no pipe.
• visited - : a dictionary of visited nodes in the current branch if not prune, or in the whole tree if prune.

Parameters:

• root - - the root node of the tree
• child_func - - the function called to get the children of a node
• prune - - don't visit the same node twice
• showtags - - print status information to the left of each node line
• margin - - the format of the left margin to use for children of root. 1 results in a pipe, and 0 results in no pipe.
• visited - - a dictionary of visited nodes in the current branch if not prune, or in the whole tree if prune.

Flatten a sequence to a non-nested list.

Flatten() converts either a single scalar or a nested sequence to a non-nested list. Note that flatten() considers strings to be scalars instead of sequences like Python would.

Flatten a sequence to a non-nested list.

Same as flatten(), but it does not handle the single scalar case. This is slightly more efficient when one knows that the sequence to flatten can not be a scalar.

This prepends newpath elements to the given oldpath. Will only add any particular path once (leaving the first one it encounters and ignoring the rest, to preserve path order), and will os.path.normpath and os.path.normcase all paths to help assure this. This can also handle the case where the given old path variable is a list instead of a string, in which case a list will be returned instead of a string.

Example:

Old Path: "/foo/bar:/foo" New Path: "/biz/boom:/foo" Result: "/biz/boom:/foo:/foo/bar"

If delete_existing is 0, then adding a path that exists will not move it to the beginning; it will stay where it is in the list.

If canonicalize is not None, it is applied to each element of newpath before use.

This appends new path elements to the given old path. Will only add any particular path once (leaving the last one it encounters and ignoring the rest, to preserve path order), and will os.path.normpath and os.path.normcase all paths to help assure this. This can also handle the case where the given old path variable is a list instead of a string, in which case a list will be returned instead of a string.

Example:

Old Path: "/foo/bar:/foo" New Path: "/biz/boom:/foo" Result: "/foo/bar:/biz/boom:/foo"

If delete_existing is 0, then adding a path that exists will not move it to the end; it will stay where it is in the list.

If canonicalize is not None, it is applied to each element of newpath before use.

Return a list of the elements in s, but without duplicates.

For example, unique([1,2,3,1,2,3]) is some permutation of [1,2,3], unique("abcabc") some permutation of ["a", "b", "c"], and unique(([1, 2], [2, 3], [1, 2])) some permutation of [[2, 3], [1, 2]].

For best speed, all sequence elements should be hashable. Then unique() will usually work in linear time.

If not possible, the sequence elements should enjoy a total ordering, and if list(s).sort() doesn't raise TypeError it's assumed that they do enjoy a total ordering. Then unique() will usually work in O(N*log2(N)) time.

If that's not possible either, the sequence elements must support equality-testing. Then unique() will usually work in quadratic time.

Adds either a bound method to an instance or the function itself (or an unbound method in Python 2) to a class. If name is ommited the name of the specified function is used by default.

Example:

a = A()
def f(self, x, y):
self.z = x + y
AddMethod(f, A, "add")
a.add(2, 4)
print(a.z)
AddMethod(lambda self, i: self.l[i], a, "listIndex")
print(a.listIndex(5))

Parameters:

• fname
• chunksize

Returns:

String of Hex digits

Collects a list of signatures into an aggregate signature.

signatures - a list of signatures returns - the aggregate signature

Parameters:

• env - - dict or dict-like object, a convainer with variables
• name - - name of the variable in env to be returned
• default - - returned when env[name] does not exist or can't be converted to bool
