For example: [daoisdasid]text
It should be text
You can use this:
local text = "[daoisdasid]text"
local newString = string.gsub(text, "%[.+]", "")
print(newString) -- "text"
string.gsub takes a string ("[daoisdasid]text"), then uses a string pattern ("%[.+]") and replaces it with a provided string ("").
Explanation of the string pattern used in this solution ("%[.+]"):
-
%signals the start of a string pattern -
[matches this specific character -
.matches any character -
+matches the maximum number of [class] characters [SEE BELOW] -
]matches this specific character
Explanation for “+”:
This character matches the maximum number of characters in a [class]:
%l+ matches the maximum number of lower case characters, or until the next provided pattern:
--// No "+"
print(string.match("abcDEF", "%l")) --> "a"
--// With "+"
print(string.match("abcDEF", "%l+")) --> "abc"
--// Next pattern, "x", provided
print(string.match("uvwxyz", "%l+x")) --> "uvwx"
In this case, .+] matches any character until it finds ].
