Namespaces are basically generic many-to-many mapping between some

jamming things into tags or bookmarks (in extension-land) and to simplify

internal bits of mercurial: log output, tab completion, etc.
|

More precisely, we define a mapping of names to nodes, and a mapping from
|

nodes to names. Each mapping returns a list.
|
|
|
|
|
|
Furthermore, each name mapping will be passed a name to lookup which might

not be in its domain. In this case, each method should return an empty list
|
|
|
and not raise an error.
|

|

'name': the namespace (plural form)

|

'templatename': name to use for templating (usually the singular form
|
|
|
of the plural namespace name)
|
|
|
'listnames': list of all names in the namespace (usually the keys of a
|
|
|
dictionary)
|
|
|
'namemap': function that takes a name and returns a list of nodes
|
|
|
'nodemap': function that takes a node and returns a list of names
