"""Exceptions for bzr, and reporting of them.
19
Exceptions are caught at a high level to report errors to the user, and
20
might also be caught inside the program. Therefore it needs to be
21
possible to convert them to a meaningful string, and also for them to be
22
interrogated by the program.
24
Exceptions are defined such that the arguments given to the constructor
25
are stored in the object as properties of the same name. When the
26
object is printed as a string, the doc string of the class is used as
27
a format string with the property dictionary available to it.
29
This means that exceptions can used like this:
33
... raise NotBranchError(path='/foo/bar')
35
... print sys.exc_type
36
... print sys.exc_value
37
... print sys.exc_value.path
38
bzrlib.errors.NotBranchError
39
Not a branch: /foo/bar
44
* create a new exception class for any class of error that can be
45
usefully distinguished.
47
* the printable form of an exception is generated by the base class
50
Exception strings should start with a capital letter and not have a final
54
# based on Scott James Remnant's hct error classes
