Parcer is a simple C parser implemented in Python. This parser is designed to tokenize C code and construct an Abstract Syntax Tree (AST).

• Tokenizes C code files.
• Recognizes delimiters, keywords, operators, and more.
• Constructs an Abstract Syntax Tree (AST) from the parsed tokens.
• Handles multi-line comments.
• Provides detailed information about each token and AST node.

   git clone https://github.com/duckduckcodes/parcer

2. cd parcer

3. python3 src/c_ast.py [file]

1. String format

for (int i = 0; i < 10; i += 1) {
    printf("%d", i);
}

Entry:: Program
  For Loop:  body: ['{', 'printf', '(', '"', '%', 'd', '"', ',', 'i', ')', ';', '}']

    Assignement:
    left: 
      Variable:
      type: int, identifier: i
    operator: =
    right: ['0']

    Loop Condition:
    left: ['i'], comparator: <, right: ['10']

    Assignement:
    left: i
    operator: =
    right: 
      Binary Expression:
      left: i, operator: +, right: 1

2. JSON format:

  "parent": null,
  "children": {
    "node_type": "For Loop",
    "body": ["{", "printf", "(", "\"", "%", "d", "\"", ",", "i", ")", ";", "}"],

      "operator": "=",
      "left": { "node_type": "Variable", "value": "i", "parent": null },

    },
    "Condition": {
      "node_type": "Loop Condition",
      "comparator": "<",

    },
    "Update": {

      }
    }
