v0.4.0

Additions

• A createMatch utility function that creates pattern-matching functions.

  // We want the match function to return a string and to accept a number
  const resolver = createMatch<string, number>([
      // Match arm which catches the values 0 or 1
      (_: 0 | 1) => "not many",
      // Match arm which catches any number less than 9
      (_: Max<9>) => "a few",
      // Match arm which catches any number that hasn't already been caught
      (_: number) => "lots"
  ]);
  
  // Transpiles to:
  const resolver = value_1 => {
      if (typeof value_1 === "number") {
          if (value_1 === 1 || value_1 === 0) return "not many";
          else if (value_1 < 9) return "a few";
          else return "lots";
      }
  };

• Eq utility marker which compares a value to an expression, skipping validation of the value type.

Changes

• Min, Max, Float, and Int utility markers now combine with the number type by default, so doing number & Min<3> for example is excessive.
• Matches utility marker now combines with the string type by default.

Bug fixes

• Unions that include the boolean type no longer generate excessive code.
• Random comments no longer get added to output (#26)
