View Source

A Makeup lexer for the Cure programming language.

Supported Cure version

The lexer tracks the surface syntax of Cure as of v0.34.0 (see the Cure CHANGELOG.md). Features covered include:

  • Container and type declarations: mod, fn, rec, type, typealias, opaque, primitive, indexed, indices, interface, implementation (and legacy proto/impl), deriving, fsm, actor, sup, app, proof, quote, unsafe, precedencegroup, infix, prefix, postfix.
  • Control flow and pattern matching: if/elif/else/then, pickup (v0.33.0+ conditional dispatch), match/when/of, for/in, try/catch/finally, throw, return, yield, end, requires, have.
  • Dependent-type constructs: assert_type, rewrite, typed holes (??, ?name), implicit arguments, predicate identifiers (even?, is_empty?).
  • FSM / actor / supervisor / application lifecycle callbacks: on_start, on_stop, on_transition, on_enter, on_exit, on_failure, on_timer, on_message, on_phase.
  • Operators & bitwise words: pipe |>, string concat <>, range .. / ..=, ellipsis ..., Melquiades send <-| (and its unicode alias ✉), binary-comprehension generator <-, bitstring segment specifier ::, augmented assignment += / -= / *= / /=, FSM transitions --event-->, monadic/applicative operators (>>=, >>, <*>, <*, *>, <$, $>), logical (&&, ||), bitwise words (band, bor, bxor, bsl, bsr, bnot), splice open $(.
  • Literals: integers (including 0xFF, 0b1010, digit-grouped), floats, booleans, atoms, chars, backtick-quoted identifiers (`foo`), strings with #{...} interpolation, regexes, maps %{...}, tuples %[...], binaries <<...>>.
  • Comments: plain #, single-line doc ##, fenced multi-line ###...### (the last two are highlighted as :string_doc).

Installation

Add makeup_cure to your list of dependencies in mix.exs:

def deps do
  [
    {:makeup_cure, "~> 0.2"}
  ]
end

The lexer will be automatically registered in Makeup for the language name "cure" and the file extension .cure.

Usage

Once installed, ExDoc and any other tool using Makeup will automatically syntax-highlight Cure code blocks (tagged with cure as the language).

You can also use it directly:

alias Makeup.Lexers.CureLexer
CureLexer.lex("fn add(a: Int, b: Int) -> Int = a + b")
