Enumerator

FULL_DESCRIPTION

NO_DESCRIPTION

Ignore this unit for documentation purposes.

HIDDEN_BUT_SHOW_MACROS

Although the unit itself is hidden, traits reachable via this unit are not hidden.

This is a bug workaround - traits are defined by WML macros, and therefore the help system has to use a place where that macro is instanciated to provide the documentation. None of the normal unit types has the "loyal" trait, but there is a hidden unit which does, purely to support the help system.

This would allow for complete customization of the contents, although not in a very easy way. It's used as the internal implementation of the other help* functions.

Precondition: The help_manager must already exist; this is different to the functions declared in help.hpp, which is why this one's declaration is in the .cpp file. Because this takes a section as an argument, it wouldn't make sense for it to call ensure_cache_lifecycle() internally - if the help_manager doesn't already exist, that would likely destroy the referenced object at the point that this function exited.
