Instead of using different modules we use a bukkit profile to test backwards compatibility with pure-Bukkit servers and use the paper-api in the default profile. This should really be done with modules in the future. The actual selection which listener to use is handled by checking if the event class exists on event registration.
This is necessary as the no_permission error was worded exactly the same making debugging more difficulty. Also this way someone who thinks he needs to access the chest doesn't think that he doesn't have access to the shop at all.
Also fix a bug where it was possible for shops to be created with shop owners that did not have a valid Account information when other plugins manipulated the name line after the NameChecker checked it. Now it gets checked twice, once at the start (to abort early and to populate the ownerAccount field) and once at the end to check again when the name line changed.
This is especially obvious for books where all the text will have color codes after dumping and loading them from the database. In order to be able to still compare to them we will load the item the item and then dump it again if it doesn't match the original one.
The configuration isn't loaded yet when the plugin loaded and the flag initialised so we can't check that there. The config option is checked at the point where the flag is handled though so there is no difference from the intended functionality when registering the flag anyways. The only downside is that this could be a tiny bit confusing to the user in the end but I think that is a small price to pay when it wouldn't be working at all otherwise.
The NameChecker now catches any exception that might be thrown when querying the account in order to properly cancel in the case of an unknown account or an error that occurred in the event to not let players create shops that they don't have access to if an exception occurs.
This fixes a bug where shop owner accounts would not be created in certain cases e.g. when the owner had certain admin permissions or created the account for another player while having certain admin permissions.
Also catch wrong types when loading the config better without completely disabling the plugin and revert "Make sure special parsers are setup" and register the parsers static again.
There might have been a case where when trying to pair the yml file with the Properties class the parsers weren't actually registered yet as nothing was called on the Properties file yet.
Also improve the ReserveListener by removing the query for the OfflinePlayer object as that's not necessary to use the Reserve economy API as it directly provides methods for UUID usage (and account existence has usually been checked before already)
Also use canAddHoldings to check if economy user can hold money instead of adding and removing.
Also add tax bypass permissions (#204, ChestShop.notax.buy/sell). When buying with that permission the buyer does not have to pay the tax (the seller will still get the reduced amount), when selling the seller will get the full amount instead of one lowered by the tax.
The permissions of the shop owner play no role due to there not being a good way of checking offline player permissions and it being a bit non-obvious for the buying/selling player if a shop would be with or without tax. This way all that gets changed is the amount the player pays/receives and not the shop owner (and the player should know their permissions/rank already)
The transfer event was necessary in order to correctly resolve who triggered the transaction. Economy adapters are now required to implement a listener for each of the events. It's also recommended that economy adapters that support transfers directly use that instead of passing it through subtract and add with the processTransfer method.
This was removed when the item transfer code changed which stopped comparators from working. This shouldn't be a true block update that observers can detect but only a notification for surrounding blocks that the content might have changed.
For some reason items might corrupt in the encoding and decoding process leading to invalid YAML strings. There's also another issue of the server not being able to load certain old itemstacks. (seems to be especially an issue with old entity types)
This is required as we now move items between inventories instead of individually removing and adding. This basically adds the stock represented by the admin shop sign to the AdminInventory so all transactions should always be possible.
This is due to a bug in CraftBukkit not properly supporting localised/translatable display names when serialising item meta.
This also adds/improves the message when no valid item ID could be generated.
This adds separate permissions for accessing, creating and destroying of shops.
It also adds a config entry to allow using of a shop even if someone have access to it due to their permissions.
The InventoryMoveItemEvent is now only used for Hopper Minecarts, other blocks that could move items (Hoppers and Droppers) are checked on place. That way players that have access to a shop can just use the blocks normally but other players can't place them.
This is necessary due to the extended length of some material names in 1.13 as they directly include the variation into the material where previously only the data value was used. (E.g. BLACK_STAINED_GLASS_PANE) By removing the spaces and using uppercase characters to separate parts the string stays both readable to the user and parseable by the plugin. It should also be backwards compatible with the old format. (At least with 1.13 material names)
This uses hardcoded widths for the main characters used in Minecraft and might not be precise for some characters but better than the previous 15 char hard limit.
This also makes it possible to input IDs on the sign that are longer than the max sign letters that the plugin uses as that just gets auto corrected back down to the correct amount.
This includes a new price_precision config entry to set the amount of decimal places to allow on a shop sign (set to 2 by default). Thanks to @andrewkm for this idea.
It also fixes an issue where a zero inside the decimal places was removed instead of it's end and also removes the point and zeros from prices that only have trailing zeros to avoid confusion (e.g. in languages that use the decimal point for thousands)
This uses a cache for players that we haven't found before so to not check the cache too often and also checks if the online mode of the queried OfflinePlayer matches the server's mode (gotten from the first logged-in player in order to be compatible with BungeeCord requiring the server to be in offline-mode.
This introduces a new AccountCheckEvent to check if a user actually has an account with the used economy plugin. Also fix CurrencyTransferEvent logic (even though it's not used anywhere currently)
