Luaās string library offers a rich set of functions for manipulating and formatting strings beyond basic concatenation. Strings in Lua are immutable, so every operation returns a new string rather than modifying the original.
Basic operations include:
string.len(s) ā length of a string.
string.upper(s) / string.lower(s) ā change case according to locale.
string.rep(s, n) ā repeat a string n times.
Concatenation with .. operator.
Substring extraction is done with string.sub(s, i, j), where indices start at 1 and can be negative to count from the end.
s = "[in brackets]"print(string.sub(s, 2, -2)) -- in bracketsGekopieerd.āKopiërenCharacter and byte conversions use:
string.char(...) ā integers to characters.
string.byte(s, i) ā numeric code of character at position i.
print(string.char(97)) -- aprint(string.byte("abc", -1)) -- 99Gekopieerd.āKopiërenSearching and replacing:
string.find(s, pattern) ā start and end indices of match.
string.gsub(s, find, replace) ā replace occurrences (supports patterns).
