Previously, the tests did not include maps with more than a single entry
since the iteration order is randomized and the tests only accepted a
single valid expected value. This commit modifies the tests to accept
multiple valid expected values and adds tests for a multi-entry map to
both Dump and Formatter.

Rather than stuffing a ConfigState instance into a separate SpewState,
just add the functionality directly to the ConfigState. This provides
simpler syntax for the consumer.
One side effect of this change is that, unlike a zero value SpewState, a
zero value ConfigState doesn't provide default values which means the
Indent field is set to provide no indentation. The consumer is now
expected to set the indent to their desired value when declaring an
instance of ConfigState.
Alternatively, the consumer can call a new function, NewDefaultConfig,
which returns a ConfigState with default values, including a default
indentation of a single space.
For example, to change the indent to a tab, the previous syntax was:
ss := new(spew.SpewState) // or var ss spew.SpewState
scs := ss.Config()
scs.Indent = "\t"
scs.Dump(whatever)
The new syntax is simply:
scs := spew.ConfigState{Indent: "\t"}
scs.Dump(whatever)

This commit implements feature request #3. In particular, it allows the
formatter to respond to %#v and %#+v. The # flag (%#v) adds type
information to the output and the combination of the # and + flags (%#+v)
adds both type information and pointer information. This allows the
consumer a choice between displaying types, pointer information, or both.

Write directly to the fmt.State output writer to avoid the overhead
of a buffer in the formatter code.

These tests are a slight adaptation of tests provided by
kortschak@ in issue #4. Credits go to him.

This was reported by korschak as issue #4 who also pinpointed the issue
and provided a patch.

There is now support for concurrent configuration through the use of
SpewState instances. Update the documenation to properly reflect this.
|
|
This commit adds a new type, SpewState, which can be used to create
instances with unique configuration options. The methods of SpewState are
equivalent to the top-level functions. Full documentation and examples
are included.
|
|
|
|
|
|
This paves the way to support individual configuration options through a
separate type while still providing the simple global config and package
level methods.
