The Usual

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

• integer literals and operations: 1 + 2 * 3
• float literals and operations: 1.0 + 2.0 * 3.0
• booleans and boolean operators (including short-circuiting): true && !(false || 1 == 2)
• character, string, and list literals and operations: "abc" ++ "def" ++ ['g', 'h', 'i']
• 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.
