The methods core_courseformat\base::set_section_number() and
core_courseformat\base:: get_section_number() have been deprecated
and replaced by core_courseformat\base::set_sectionnum() and
core_courseformat\base::get_sectionnum().
The new methods use the null value when all the sections must be
displayed (instead of 0). That way, section 0, can be displayed on
a single page too.
After UX research, the conclusion is that all formats should use "section"
and not try to use alternative terms such as topic or week.
This commit replaces topic and week references with section. A couple of
considerations:
- Most of the strings in topics and weeks formats have been removed. In that
particular case it's not required to follow the deprecation process because
they will be using the generic ones defined in moodle or courseformat.
- The sectionname will be renamed from "Topic"/"Week" to "New section" in
MDL-80460.
