How can I delete everything past a word in a string?

Help and Feedback Scripting Support
#1

I have a string for my tutorial system and at the end I specify what action it is, example: {Text}

I want everything after a certain word to be taken out and stored as a variable, whenever I do {Arrow} I want to be able to specify the position so how can I get that?

Example: “textblabla! {Arrow=10,0,10}”

You can use capture groups in string pattern matching!

local s = [[textblalbla! {Arrow=10,0,10}]]
local pattern = "{(.-)=(.-)}"
local name, value = s:match(pattern)
print(name, value)

Or if you have multiple occurences:

local s = [[textblalbla! {Arrow=10,0,10} {Test=ayyy}]]
local pattern = "{(.-)=(.-)}"
for name, value in s:gmatch(pattern) do
    print(name, value)
end

No problem! Ask away if you want an explanation of the string pattern, or maybe just look around on the internet for a reference for string patterns :slight_smile:
