* Server: delegate mod management & config to ServerModConfiguration (rename it to ServerModManager)
* Use c++11 range based loops
* Add unittests + experimental/default mod as a test case to permit testing mod loading in future tests
* Modernize various files (src/m*)
* range-based for loops
* code style
* C++ headers instead of C headers
* Default operators
* empty function
Thanks to clang-tidy
* Allow enabling and disabling mods.
* Re-fix 605599b6f150b89ba6539c4d088231b326adcb48
This breaks some chars like € in chat.
Instead verify is char is a non control char -> iswcntrl
* client side mods are located in clientmods/
* move builtin/preview.lua to clientmods/preview/init.lua as a preview mod
* refactor ModConfiguration class to work properly with client and server using child objects
* move some Server constructor mod load code to ModConfiguration to reduce code duplication between client and server
* remove mods.{cpp,h} unused functions
* use UNORDERED_SET instead of std::set in some modspec storages
* mod can create a ModMetadata object where store its values and retrieve it.
* Modmetadata object can only be fetched at mod loading
* Save when modified using same time as map interval or at server stop
* add helper function to get mod storage path
* ModMetadata has exactly same calls than all every other Metadata
* Move included json code to jsoncpp subdirectory
This is needed to avoid having to specify the minetest src directory
as a system include when fixing the json includes.
* Fix json includes
They used "", so that the compiler searches the project's directory
first. The result was that when compiling with a system jsoncpp,
the project's own version of json.h was still included, instead of
the system version.
The includes now use <>, so a system location, or one specified with
'-Ilocation' is searched only.
* Fix for jsoncpp deprecated function warning
When compiling with a newer version of jsoncpp (and
ENABLE_SYSTEM_JSONCPP=true), jsoncpp emits a warning
about a deprecated function that minetest uses.
Previously, the server called FATAL_ERROR when a Lua error occured.
This caused a (mostly useless) core dump.
The server now simply throws an exception, which is caught and printed before
exiting with a non-zero return value.
This also fixes a number of instances where errors were logged multiple times.
Only show enable all / disable all buttons for all add-ons when at
least one add-on is installed. When no add-on ist installed, don't
show any buttons or checkboxes.
Added is_modpack flag to ModSpec to distinguish empty modpacks from
normal mods and check this flag in mod selection gui so that empty
modpacks are not treated like mods that can be enabled or disabled.
settings.h: added function to return all keys used in settings, and a
function to remove a setting
mods.{h,cpp}: added class ModConfiguration that represents a subset of the installed mods.
server.{h,cpp}: server does not load add-on mods that are disabled in
the world.mt file. mods are disabled by a setting of the form
"load_mod_<modname> = false". if no load_mod_<modname> = ... setting
is found, the mod is loaded anyways for backwards compatibilty. server
also complains to errorstream about mods with unstatisfied
dependencies and about mods that are not installed.
guiConfigureWorld.{h,cpp}: shows a treeview of installed add-on mods
and modpacks with little icons in front of their name indicating their
status: a checkmark for enabled mods, a cross for disabled mods, a
question mark for "new" mods
Mods can be enabled/disabled by a checkbox. Mods also show a list of
dependencies and reverse dependencies. double-click on a mod in
dependency or reverse dependency listbox selects the corresponding
mod. Enabling a mod also enables all its dependencies. Disabling a mod
also disables all its reverse dependencies.
For modpacks, show buttons to enable/disable all mods (recursively,
including their dependencies) in it.
Button "Save" saves the current settings to the world.mt file and
returns to the main menu. Button "Cancel" returns to main menu without
saving.
basic keyboard controls (if the proper widget has keyboard focus):
up/down: scroll through tree of mods
left/right: collaps/expand a modpack
space: enable/disable the selected mod
