Yue auto remove extra parentheses when not intent

[GokuHiki]

I like to use () to select only the first result when return from a function call.

EX:

gsub_plaintext = (str, search, replace) ->
  local escaped_search = search::gsub("([%%%.%[%]%^%$%(%)%*%+%-%?])", "%%%1")
  local escaped_replace = replace::gsub("%%", "%%%%")
  -- parentheses are used to return only the string result
  return (str::gsub(escaped_search, escaped_replace))

print gsub_plaintext("abc def ghi", "def", "xyz")
print gsub_plaintext("abc def ghi", "def", "%%1")

But, Yuescript auto remove the extra parentheses as:

local gsub_plaintext
gsub_plaintext = function(str, search, replace)
  local escaped_search = search:gsub("([%%%.%[%]%^%$%(%)%*%+%-%?])", "%%%1")
  local escaped_replace = replace:gsub("%%", "%%%%")
  return str:gsub(escaped_search, escaped_replace)  -- the extra parentheses is removed
end

print(gsub_plaintext("abc def ghi", "def", "xyz"))
return print(gsub_plaintext("abc def ghi", "def", "%%1"))

Output:

abc xyz ghi	1
abc %%1 ghi	1

Is this behavior is intended? I think it's better to follows to keep the parentheses to achieve the Lua behavior as intended.

Thanks and regards.

I’ve confirmed that this behavior wasn’t intended. The issue stemmed from YueScript attempting to remove some automatically inserted parentheses during compilation. To address this, I’ve introduced a new flag to differentiate between parentheses added by the user and those inserted by the compiler. It should work as expected now.

Confirm fixed!
