Explicitly use t_str() to avoid an ambiguous construction from
7bee8ee157, which made GCC9 error out because it
could alternatively use t_string::t_string(const string &).
Resolve the merge conflict from 26d1ca7a7d
Possible fix for #4058, with the following logic:
* If non-empty, [unit]overlay= is handled by adding modifications
* unit::write will always output an empty overlay=
* The Lua API's get_units() will still provide the list of overlays
* [effect]apply_to=overlay can now remove as well as add overlays
* [remove_unit_overlay] is implemented with [effect]apply_to=overlay
Using [object]s with durations hasn't been tested, but expected effects:
* An expired add= followed by a non-expired remove= will simply cause the remove=
to have no effect when std::remove(overlays_ ...) is called.
* A remove= followed by [remove_unit_overlay] cause the [remove_unit_overlay] to be a no-op,
and the overlay will reappear when the first remove= expires. This edge case is already
documented as unsupported on the wiki.
This makes [movetype] consistent with [unit]. The code in movetype.cpp is used
for handling both of those tags and so already had support for "flying" in the
merge() and write() functions.
This shouldn't be backported to 1.14. For this reason, it also includes
handling the C++ todos to use C++14's std::make_unique.
When multiple negative heal abilities are present, the game now
chooses the ability with the lowest value. The leadership ability
now also uses the same get_composite_value function that is also
used by most other abilities
This adds running the WML schema validation in travis. It also updates the schema itself and fixes a few WML errors so that core and all campaigns under all difficulties pass the schema validation.
Currently this is disabled by default
Use --validate command-line argument to enable
The following new features were added in the schema format:
* Union, intersection, and list types
* Keys can specify a union of known types on-the-fly
* Key and tag names can include wildcards (* and ?, glob-style)
* Tags support any_key=yes, which means unrecognized subtags will be ignored
* Tags and keys support deprecated=yes (unimplemented)
* Specify max=infinite instead of max=-1
