A dynamically-typed, C-based syntax programming language. Supports arithmetic operations, conditional statements, and loops. Written in Python 3.

1. Clone or download this repository.

2. Navigate to project's root directory.

3. On the terminal, run the command below to start the Gelic interactive mode:

   • python3 .\gelic.py

   To run an external .txt file execute the command below. A test folder is provided for sample programs:

   • python3 .\gelic.py .\test\fib.txt

• Booleans:
  • true; // not false
  • false: // not *not* false
• Numbers:
  • Gelic has only one kind of number: floating point.
  • 1234; // evaluated as 1234.0
  • 12.34; // float
• Strings:
  • Gelic strings are enclosed in double quotes.
  • "Gelic uses double quotes for strings."
  • "";
  • "123";
• Nulls:
  • Gelic uses the nil keyword to represent "no value".

• Arithmetic:
  • Gelic supports basic arithmetic operations just as C does.
  • The minus operator is both used as in infix and a prefix. '-' can be used to negate a number:
    • -2;
• Comparison and Equality:
  • Gelic also supports comparison operators:
    • 3 < 4; // true
    • 3 <= 3; // true
    • 6 > 10; // false
    • 6 >= 7; // false
    • 1 == 2: // false
    • "cat" != "dog"; // true
• Logical Operators:
  • The not operator, a prefix !, returns false if its operand is true, and vice versa.
    • !true; // false
    • !false; // true
  • and and or logical operators, identical with C's && (and) and || (or)
    • true and false; // false
    • true and true; // true
    • false or false; // false
    • true or false; // true
• Precedence and grouping
  • Gelic's operators have the same precedence and associativity as C.
    • var average = (min + max) / 2;

• Print
  • print evaluates a single expression and displays the result to standard output. Syntax is similar to Python 2.
    • print "Hello, world"; // Hello, world
