This includes also the query data for the help system (F1) for an
identifier under cursor.
Regressions (libclang changes necessary):
- Function signatures do not contain default values.
- Aliases are not resolved for/at:
- template types
- qualified name of a type
Fixes/Improvements:
- Resolve "auto"
- On a template type, show also the template parameter.
- For a typedef like
typedef long long superlong;
the tooltip was "long long superlong", which was confusing.
Now, "long long" is shown.
New:
- Show first or \brief paragraph of a documentation comment.
- Show size of a class at definition.
- Show size of a field member in class definition.
