Semantics

The program will automatically stop running at the end. Each program consists of a number of lines (separated by a line break (which follows the platform, for example, for NT Windows, it is \x0D\x0A) or a semicolon).

Data types

The following data types are present in CollaborativePL:

Numbers

There are three numeric types in the language: integers, decimal floating point numbers and complex numbers.

Integers not only can be written in decimal, e.g. 1203, but you can specify the base using Unicode subscript characters (₀₁₂₃₄₅₆₇₈₉), e.g. 3F2A₁₆.

Negative numbers are marked with ¯ before the number.

Floating-point numbers can have an exponential part as well as a decimal part, e.g. 6.02e23(It is equivalent to 6.02×10²³, which is 602,000,000,000,000,000,000,000).

Complex numbers are written with an i separating the real and imaginary parts.

There are also the following special constants: π, τ (tau, which is 2 times pi), φ ( = (√5 + 1) / 2 ) ∞ (countable infinity), Ω(Cantor's Absolute Infinity) and ⸮ (NaN).

The special "wildcard value" ⸮⸮ (two NaN symbols) is equal to {x|x∈ℂ} where ℂ means all numbers, either complex or real.

Strings

Strings are written in double quotes, e.g. "Hello, world!" The following escape codes are available:

Caption text

Escape code	Character it represents
\n	Newline
\t	Tab
\r	Carriage return
\0	Null character
\d{19968}	Any Unicode character but in decimal
\f{expression}	Reference to an expression
\x74	Any Unicode character between U+0000 and U+00FF
\u7429	Any Unicode character between U+0000 and U+FFFF
\u{17429}	Any Unicode character

Operators

See CollaborativePL/Operators for the comprehensive list of operators.

Ports

Currently, we support the following ports: ⎕ (standard input and standard output), ⌸ (evaluation input), ⍔ (unbuffered error output), ⌻ (buffered error output), ⍂ (popup output), ⍞[filename] (read/write files).

You can do I/O by assigning to these ports. For example,

⎕ ← ⎕

Interesting tools

There is an available "emotional damage" operator which has 0 operands and makes Steven He give you MAXIMAL EMOTIONAL DAMAGE!
