═══════════════════════════════════════════════ AlienCode — Language Reference Manual ═══════════════════════════════════════════════
AlienCode is a simple calculation language. All operations use function-call syntax. Below is the complete spec.
────────────── Values ────────────── Integers 42, -5, 0 Floats 3.14, -0.5 Strings "hello", "world" Booleans YES (true) NO (false)
────────────── Assignment ────────────── SET x AS 5 assign 5 to x SET x, y AS 1, 2 multiple assignment
────────────── Output ────────────── EMIT(x) display x EMIT(x, y, z) display several values (space-separated)
────────────── Arithmetic ────────────── SHATTER(a, b) addition a + b WEAVE(a, b) subtraction a − b PARE(a, b) multiplication a × b FRACTURE(a, b) division a ÷ b COIL(a, b) power a ^ b RESIDUE(a, b) modulo a mod b HALVE(a, b) integer div a ÷ b (rounded down)
────────────── Comparison ────────────── AKIN(a, b) equal a == b APART(a, b) not equal a ≠ b OVER(a, b) greater a > b UNDER(a, b) less a < b ATOP(a, b) greater-or-eq a >= b BENEATH(a, b) less-or-eq a <= b
────────────── Logic ────────────── BOND(a, b) logical AND RIFT(a, b) logical OR NEGATE(a) logical NOT
────────────── Sequences ────────────── STRAND(1, 2, 3) create list [1, 2, 3] KNOT(1, 2, 3) create tuple (1, 2, 3) PLUCK(seq, i) element at index i (0-based) CARVE(seq, start, stop) sub-sequence seq[start:stop] ANNEX(seq, val) append val to end of seq EXPEL(seq) remove & return last element IMPRINT(seq, i, val) assign val to seq[i] (0-based)
────────────── Aggregation ────────────── GAUGE(seq) length of seq NADIR(a, b, …) minimum value APEX(a, b, …) maximum value SOME_OF(seq) true if any element is true EVERY_OF(seq) true if all elements are true ORDER(seq) sorted copy (ascending) GATHER(iter) convert iterator to list FUSE(a, b, …) concatenate values as string
────────────── Iteration ────────────── EXTENT(n) [0, 1, …, n-1] EXTENT(a, b) [a, a+1, …, b-1] INDEX(seq) yields (index, value), index starts at 0 PAIR(a, b) pairs corresponding elements of a and b STRAIN(func, seq) keeps elements where func(x) is true
────────────── Control Flow ────────────── UPON condition: if … LEST condition: else-if … DEFAULT: else … SWEEP var IN iterable: for loop … WHILE condition: while loop … CEASE break BYPASS continue
────────────── Functions ────────────── CRAFT name(args): define function … DELIVER value return value
