🦎 Lizard Language

**Lizard** is a small, C‑based interpreted language designed for learning and experimentation. It supports variables, arithmetic, comparisons, conditionals, and string concatenation in `print` statements.

Features

• Variables – integers, float, boolean and strings
• Assignment – =
• Logical Operator – and, or, not
• Compound Assignment – = += -= *= /=
• Arithmetic – + - * / ++ -- and parentheses
• Comparisons – == != < > <= >= (return 1 or 0)
• Print – print(...) with + concatenation (strings, ints, variables)
• Conditionals – if, elif, else with { } blocks
• Loops – while
• File extension – .lzd
• Version – Lizard -v shows ASCII art

Building

Clone the repository and compile with make:

git clone https://github.com/Luifegames/Lizard-Language.git
cd lizard
make

The executable lizard (or Lizard.exe on Windows) will be created.

Usage

Run an Lizaes script:

./lizard script.lzd

Show version:

./lizard -v

Example

Create a file hello.lzd:

name = "Lizard"
size = 10

if (size >= 10) {
    print("Welcome to " + name + "!")
} else {
    print("too small")
}

print("2 + 2 = " + (2 + 2))
print("5 > 3 is " + (5 > 3))

Run it:

./lizard hello.lzd

Output:

Welcome to Lizard!
2 + 2 = 4
5 > 3 is 1

UTF‑8 Support

Lizard reads .lzd files in binary mode and preserves UTF‑8 byte sequences inside string literals. To display accented characters (á, é, í, ó, ú, ñ) correctly:
