# Paid signs

The paid-signs plugin is a plugin that lets you add costs for creating plugin signs. This allows restricting usage of
signs such as CraftBook's gate/lift and other signs while still allowing every player to create the signs.

Note: OP players, and players with the '*' permission will have the `paidsigns.paymentexempt` permission and will not
see any payment messages. For testing, you'll need to un-set the `paidsigns.paymentexempt` permission.

## Limitations

As this plugin only listens to sign change events, there are some limitations:

1. The plugin is not aware of whether the creation of a sign is successful. Setting the appropriate permission might
   help, but it's not guaranteed
2. It is assumed that any protection plugins run before this plugin checks a sign, but it's not guaranteed
3. Plugins changing the lines on signs when successful might create confusion and mismatches if changes happen before
   this plugin checks a sign

## FAQ

### A player placed down a sign, but some plugin broke it afterwards. What do I do?

There are three ways this can be solved:

1. Make the player (or anyone else) place an empty sign in the same location and break it again. The player should be
   refunded as long as refunds are enabled.
2. Reload PaidSigns. The player should be refunded as long as refunds are enabled.
3. Restart the server. The player should be refunded as long as refunds are enabled. Never place a new paid sign in the
   same location in this situation, as the old sign will be overwritten, and the ability to refund the player
   automatically will be lost.

### Players have to pay for signs, even if the plugin sign isn't created

This is a known limitation of this plugin. As long as this plugin is agnostic to the plugin signs it's used for, it
cannot really know if a plugin sign has been created. The best you can do is finding the permission required for the
plugin sign and specifying it when creating the paid sign. It can be assumed that the player is able to create the
plugin sign, if the player has the correct permission.

### How can this plugin be used to enhance a server?

This plugin is known to be helpful with two tasks:

1. Allow normal players to create plugin signs, such as CraftBook's elevator signs, but at a cost. This can be done by
   simply specifying the exact text required for the plugin sign in the paid sign conditions.
2. Add a swearing jar/swearing filter to the server. This can be done with a paid sign matching ANY condition, where the
   list of swear words is given as a regEx. The same regEx should be added for each of the four sign lines.

## Custom parser

Before anything else, it's important to note that as an experiment, I used a custom command-parser for this plugin. This
means that sign names can contain spaces, as long as the name is in quotes. In most cases, this actually works fine,
even though it differs a lot from the default behavior, but if you tab-complete the first word in the name first, and
then try to tab-complete the rest, tab-completion will fill in the second world with the entire name, which is
unfortunate. That's really just how tab-completion works, and not something I think I can do anything with.

## Commands

An argument marked by "<>" is required to execute the command. An argument marked by "[]" is optional. For empty
arguments, such as no paid sign permission, you should use empty quotes ("").

## Command explanation

### /addpaidsign

This command adds a new paid sign that does nothing until a condition is added.

`/addpaidsign <name> <cost> [permission] [ignore case] [ignore color] [match any condition]`

| Argument | Usage |
| ----- | ----- |
|name | A recognizable name only used to differentiate between registered paid signs |
|cost | The cost a player needs to pay to create any sign matching the paid sign |
|permission | If the paid sign is used to represent a plugin sign, the permission should be the permission necessary for creating the plugin sign. This is used to decide if the plugin sign was created, or if the player was denied. |
|ignore case | Whether any conditions of the paid sign should ignore case by default, when matching against text (default uses the config file value). |
|ignore color | Whether any condition of the paid sign should ignore color by default, when matching against text (default uses the config file value). |
|match any condition | Whether to trigger a paid sign match if a single one of the sign's conditions is true. This is mainly useful if several lines may contain the match string, or if trying to match a word. |

### /addpaidsigncondition

This adds a condition to a paid sign which is used to decide if a sign created by a player matches the paid sign. Adding
a paid sign condition to a line that already has one will replace the previous condition.

`/addpaidsigncondition <name (of a paid sign)> <line number> <string to match> [executeRegEx] [ignoreCase] [ignoreColor]`

| Argument | Usage |
| ----- | ----- |
| name | The name of the paid sign to add the condition to |
| line number | The line on the sign (1-4) to search for any matches |
| string to match | The string or regular expression to look for on a sign |
| executeRegEx | Whether to use a regular expression match instead of looking for the exact string |
| ignoreCase | Whether this condition should ignore case when trying to match the string (default uses the "parent" sign's value) |
| ignoreColor | Whether this condition should ignore color when trying to match the string (default uses the "parent" sign's value) |

### /listpaidsigns

This lists registered paid signs and paid sign conditions. No arguments will print a list of paid signs

`/listpaidsigns [page number]/[name (of a paid sign)] [line number]`

| Argument | Usage |
| ----- | ----- |
| page number | Paid signs are listed 7 at a time, so the page number is used to see the next 7 |
| name | The name of the paid sign to see information about |
| line number | The line number of the condition to see information about |

### /editpaidsign

This command changes a property of a paid sign or a paid sign condition

`/editpaidsign <sign name> <property>/<line number> [new value]/<property> [new value]`

| Argument | Usage |
| ----- | ----- |
| name | The name of the paid sign to edit |
| property / line number | The property to edit for the sign (name, cost, permission, ignoreCase, ignoreColor, matchAnyCondition), or the line of the condition to edit |
| new value / property | The new property value if a property was specified in the second argument, or a condition property (stringToMatch, executeRegEx, ignoreCase, ignoreColor) if a line number was specified in the second argument |
| new value | The new property value of the condition property specified in the third argument |

### /removepaidsigncondition

Removes a paid sign condition from a sign

`/removepaidsigncondition <name (of a paid sign)> <line number>`

| Argument | Usage |
| ----- | ----- |
| name | The name of the paid sign to remove the condition from |
| line number | The line the condition is associated with |

### /removepaidsign

Removes a registered paid sign

`/removepaidsign <name (of a paid sign)>`

| Argument | Usage |
| ----- | ----- |
| name | The name of the paid sign to remove |

## Permissions

| --paidsigns.manage | Grants the permission to add/remove a paid sign |
| --paidsigns.reload | Grants the permissions to reload the plugin |
| --paidsigns.paymentexempt | Makes this player exempt from the cost of paid signs |

## Configuration options

| Option | Description |
| ------- | ------- |
| language | The language to use for all messages displayed to players. Currently, only "en" is valid. |
| ignoreCase | Whether to ignore the case (lowercase/uppercase) of the paid sign text. The option can be set on a per-sign basis, but this value is used if not specified. The correct value depends on whether the plugin signs it should match are case-sensitive or not. |
| ignoreColor | Whether to ignore any color or formatting applied to the text when trying to match a paid sign's text. The option can be set on a per-sign basis, but this value is used if not specified. The correct value depends on whether the plugin signs it should match allow coloring or not. |
| refundsEnabled | Whether to enable refunds to the sign creator when a sign detected as a paid sign is broken (payment will always go to the original creator) |
| refundPercentage | The percentage of the paid sign cost to refund (0-100) |

## Language customization

All strings, even time units, are customizable. If you place a strings.yml file in the plugin folder, it will take
priority over built-in languages. If you want to change strings, look
at [PaidSigns/src/main/resources/strings.yml](https://git.knarcraft.net/EpicKnarvik97/PaidSigns/src/branch/master/src/main/resources/strings.yml)
for the proper keys. All strings have the format: ENUM: "Displayed string". The enum must be identical as it defines
which string you have changed. All strings belonging to a language are beneath the language code and indented with two
spaces.

The easiest way to add a new language is to copy an existing language and paste it into your custom strings.yml and
change strings as necessary. If you don't include all strings, the remaining will use the built-in English translation.
Remember to change the language code to whichever you use for your custom language.
