# String Utilities Mod
A mod that provides more NBT string operations.\
一个提供更多 NBT 字符串操作的模组。
## Syntax 语法
`/string [target] [source...]`
The `target` and `source` parts are similar to what follows the `data modify` command.\
`target`和`source`部分与`data modify`命令后面的部分类似。
## Example 例子
- `/string isEmpty value ""` returns 1
- `/string indexOf value "asdfghjkl" value "qwerty"` returns -1
- `/string escape storage a:b c value '\'quote"slash\\'` stores `'quote\"slash\\` into `a:b/c`
- `/string strip storage foo:bar baz value " a 123 "` stores `a 123` into `foo:bar/baz`
- `/string concat2 storage a b from entity @s SelectedItem.id from entity @s Inventory[0].id`
- `/string join storage test playerUUID from value "~" from @s UUID`
