Utilities

Extensions to the standard Lua string library.

• string.split(str, sep) -> array
  Split string by separator.
• string.trim(str) -> string
  Remove whitespace from both ends.
• string.starts_with(str, prefix) -> bool
• string.ends_with(str, suffix) -> bool
• string.random(len) -> string
  Generate random alphanumeric string.

Extensions to the standard Lua table library.

• table.keys(tbl) -> array
  Get all keys of a table.
• table.values(tbl) -> array
  Get all values of a table.
• table.merge(t1, t2) -> table
  Merge two tables (shallow copy). t2 overwrites t1.
• table.map(tbl, fn) -> table
  Apply function to each element.
• table.filter(tbl, fn) -> table
  Return new table with elements passing the predicate.

Cryptographic utilities via crypto global.

• crypto.md5(data) -> string
• crypto.sha256(data) -> string
• crypto.base64_encode(data) -> string
• crypto.base64_decode(data) -> string
• crypto.uuid() -> string (v4)
• crypto.jwt_encode(claims, secret) -> string
• crypto.jwt_decode(token, secret) -> table
• crypto.hash_password(pwd) -> string
  Argon2 hashing (Async).
• crypto.verify_password(hash, pwd) -> bool

Time utilities via time global.

• time.now() -> float (seconds)
• time.iso() -> string (ISO 8601)
• time.sleep(ms) -> nil
  Suspend execution for N ms (Non-blocking).
• time.format(ts, format) -> string
• time.parse(iso) -> float (seconds)

JSON encoding and decoding via global json table.

• json.encode(value) -> string
  Convert Lua value (table, string, number, bool, nil) to JSON string.
• json.decode(str) -> value
  Parse JSON string to Lua value.

-- Encode Lua table to JSON
local data = { name = "Alice", age = 30, active = true }
local json_str = json.encode(data)
-- '{"name":"Alice","age":30,"active":true}'

-- Decode JSON string to Lua table
local parsed = json.decode('{"foo":"bar","nums":[1,2,3]}')
print(parsed.foo)      -- "bar"
print(parsed.nums[2])   -- 2
