vc (Varyx Calculator)

https://www.vcode.org/vc/

vc is a command-line calculator. Its purpose is to prototype the development of Varyx’s parser and expression engine. Think of it as an embryo or larval stage to the Varyx programming language.

The vc source code is AGPL-licensed and published on GitHub.

Progress

Big integers up to 2^2^20 (can be trivially increased to 2^2^36)
strings (including \u1234 and \u{12345} escape sequences)
heterogenous arrays
user-defined code blocks
map operator
true and false
optional type annotations
integer type refinements: i8, u8, i16, u16, i32, u32, i64, u64
rational numbers
byte type (distinct from u8 integers)
comma-separated lists (with empty list as ())
constants and variables (declared by let (or const) and var)
unary +, -
binary arithmetic +, -, *, /, div, %, mod, and ^ (exponentiation)
equalities (== and !=)
inequalities (<, <=, >, and >=)
left unary (+) for list count
infix binary (*) for list multiplication
partial application of function arguments with %
pure functions area(), abs(), half(), join(), typeof(), hex(), unbin(), and unhex()
type-safe assignment with =, +=, -=, *=, /=, %=
lossy assignment with :=
multiple statements, separated by ;
if/then/else

Future Directions
