Change the Lua implementation to directly call the
non-deprecated function, this is related to 9daa10a9f2.
Clean up the C++ header files by removing the declarations of
functions that were removed in 3c8de46771.
Use [endlevel]end_credits=no in the test scenario (trigger it
by moving to hex 9,3). If you debug with :next_level without
triggering the moveto, "The End" will show; trigger the moveto
first, and it won't show the credits.
This adds an additional `test_result` attribute to [endlevel], intended for use with the automated unit tests. This allows for the unit tests to differentiate a pass/fail result separately from scenario victory or defeat, which allows for more accurately determining the outcome of a test as well as addresses the potential, for example, for a scenario to be expect to pass because of the {SUCCEED} macro but instead passes because the scenario ended as a victory through some other method.
Additional unit tests which were the original motivation for this change are also added as part of this. They test, as much as possible, that events are executed at all, and are then also executed in the expected order.
fix code problems found by luacheck
Second iteration of the process, now handling data/lua/wml/*.lua
luacheck command used to find bugs:
luacheck ./*.lua --globals wesnoth wml --codes --ignore 542 213
Additionally, error code 211 (unused variables) could be ignored,
as using underscore convention `_` is controversial in
wesnoth ( see https://github.com/wesnoth/wesnoth/pull/2380#discussion_r162519341 )
Actual bugs found:
* items.lua, access of global `write_name` instead of local `cfg.write_name`
* kill.lua, typo `primary_unit` -> `primary`
* bad code style: global `i` instead of local `i`
(would conflict with 3-rd party code if it would use global `i`, too)
In cbd3c2644, a Lua API to victory and defeat music was added, which exposes it as a vector of strings.
However, the [endlevel] implementation passed the comma-separated string directly.
This commit splits the string before passing it to the Lua API.
