Custom Syntax for Python Language -- CSPLang

CSPLang – Custom Syntax for Python Language

GITHUB: https://github.com/Ansari-Codes/custom-syntax-for-python
PYPI: https://pypi.org/project/csp-lang/

CSPLang is a high-speed, symbolic syntactic wrapper for Python. It transforms a compact, symbol-heavy DSL into executable Python code. Designed with the principle of "Write less, do more," CSPLang turns Python's keyword-heavy structure into a sleek, streamlined experience.

The CSPLang Philosophy: What if you had the full power of the Python ecosystem, but with the minimalist elegance of a functional language?

🚀 Key Features (v2.0)

• Recursive One-Liners: Define functions, loops, and conditions all on a single line.
• Context-Aware Parsing: Intelligently distinguishes between logic colons and data colons (like in dictionaries or list slices).
• Symbolic Identity: Replaces verbose keywords (def, while, return) with intuitive symbols ($, >>, ->).
• Zero-Overhead Integration: Use any Python library (numpy, tqdm, asyncio) out of the box.

📝 Syntax Overview

1. Variables & Assignment

Use the "flow" operator <- for assignment.

name <- `Abubakar`
age  <- 19
data <- [1, 2, 3]

2. Universal Strings

Forget f"", "", or ''' '''. Use backticks for everything. They support multiple lines and escaped backticks (`).

msg <- `This is a 
multi-line string with a \`backtick\` inside.`

# F-strings work naturally:
print(f`Hello, {name}!`)

3. Conditionals (Implicit If)

No need to type if. A standalone condition ending in a colon is automatically treated as a conditional.

x <- 10

x > 5:               # This is 'if'
    print(`Large`)
: x == 5:            # This is 'elif'
    print(`Medium`)
:                    # This is 'else'
    print(`Small`)

# NEW: One-liners are now supported!
x == 10: print(`Perfect Score`)

4. Loops

• While: Use >>
• For: Use => (where : replaces in)

# While Loop
count <- 3
>> count > 0: 
    print(count) 
    count <- count - 1

# For Loop
=> i:range(3):
    print(f`Iteration {i}`)

5. Functions & Methods

Defined using $ and []. The -> symbol acts as the return.

# Standard definition
$add[a, b]:
    -> a + b

# Works inside classes too!
class Math:
    $cube[self, n]: 
        -> n ** 3

⚡ Extreme Flexibility (v2.0 Stress Test)

Because CSPLang v2.0 uses a Recursive Split Strategy, it can handle complex Python constructs mixed with CSP symbols without breaking.

# Slicing and Dictionaries work perfectly!
data <- [10, 20, 30, 40]
subset <- data[1:3]             # Transpiler ignores the slice colon
results <- {`val`: subset[0]}    # Transpiler ignores the dict colon

# Complex nesting and one-lining
$check[n]: 
    >> n > 0: 
        n%2==0:
            print("Even: ", n)
        :n%2!=0: print("Odd: ", n)
        :print(n in [1, 2, 3, 4][:2])
        n <- n - 1
check(10)
