NameData Actions
DescriptionSeveral commands function as a way to modify data values,
including Command:flag, Command:yaml, and Command:define.
These commands each allow for a set of generic data change operations.

These operations can be used with a syntax like "<key>:<action>:<value>"
For example "mykey:+:5" will add 5 to the value at 'mykey'.

The following actions are available:

Actions that take no input value:
Increment: '++': raises the value numerically up by 1. Example: - define x:++
Decrement: '--': lowers the value numerically down by 1. Example: - define x:--
Remove: '!': removes the value entirely. Example: - define x:!

Actions that take an input value:
Add: '+': adds the input value to the value at the key. Example: - define x:+:5
Subtract: '-': subtracts the input value from the value at the key. Example: - define x:-:5
Multiply: '*': multiplies the value at the key by the input value. Example: - define x:*:5
Divide: '/': divides the value at the key by the input value. Example: - define x:/:5
List insert: '->': adds the input value as a single new entry in the list (see also 'List split'). Example: - define x:->:new_value
List remove: '<-': removes the input value from the list. Example: - define x:<-:old_value
List split: '|': splits the input list and adds each value into an existing list at the key. Example: - define x:|:a|b|c

Special cases:
In some commands, specifying no action or input value will automatically set the key's value to 'true'.
Setting a '<key>:<value>' without an action will set the key to the exact value. Be careful to not input a list like this, use 'split to new' instead.

Note that the <key> input may take an index input as well, for example "mykey[3]:value".
This also works with most actions.
That is, for example: "mykey[3]:--" will decrement the third item in the list at 'mykey'.
This syntax may also be used to remove the entry at a specified index, for example "mykey[3]:<-"
The index can also be "last" to automatically use the last entry in the list as the target.
