* 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
Changes:
* Fix indentation.
* Pass strings by const reference.
* Merge Strfnd and WStrfnd into one class instead of copying them.
* Remove trailing spaces.
* Fix variable names.
* Move to util.
* Other miscellaneous style fixes.
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.
Move debug streams to log.cpp|h
Move GUI-related globals to clientlauncher
Move g_settings and g_settings_path to settings.cpp|h
Move g_menuclouds to clouds.cpp|h
Move g_profiler to profiler.cpp|h
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
This is not a problem on POSIX systems (these directories are
ignored by the POSIX implementation of fs::GetDirListing() in
filesys.cpp), but these directories still are reported on Windows
systems. This becomes a problem when mod authors use version
control systems that create directories like ".git" or ".svn"
and collectMods() picks up on them. It has also been suggested
that ignoring such directories would allow for the easily disabling
mods by inserting a "." in front of their name.
This quick fix simply makes collectMods() ignore directories
beginning with a ".".
