The Usual

Vine has the usual complement of standard programming language features, including:

• integers: 1 + 2 * 3
• floats: 1.0 + 2.0 * 3.0
• booleans (including short-circuiting): true && !(false || 1 == 2)
• lists: [1, 2, 3] ++ [4, 5, 6]
• strings: "abc" ++ "def"
• tuples: (1, 1.0, "abc"), (1, 2).0
• variables: let x = 5; x += 1
• basic control flow:
  • if condition { ... } else { ... }
  • while condition { ... }
  • loop { ... } (loops until break)
  • return value
  • break, continue
  • loop labels: while.label ... { ... break.label ... }

(Try some of these snippets in the vine repl!)

Many of Vine's features are influenced by Rust, and it has a similar expression-oriented syntax, type system, and module system.
