💿Compilation Process

The entire Maryl compilation process is explained here

1. Input File

• The process begins with a file named HelloWorld.mrl.

---

2. Parsing of the File

• The file undergoes a parsing step to ensure it adheres to the required syntax and format.

---

3. Error Handling (Initial Parsing Phase)

• After parsing:

  • If an error is found: The error is flagged and sent to the error-handling mechanism.

  • If no error is found: The process continues to the conversion step.

---

4. Conversion to Assembler

• The parsed file is converted into assembler code, a low-level representation of the program.

---

5. Virtual Machine Processing

• The assembler code is retrieved and parsed by the Virtual Machine (VM) for further analysis.

---

6. Error Handling (Virtual Machine Phase)

• At this stage:

  • If an error is encountered: The error is processed, and the workflow terminates with an error message.

  • If no error is encountered: The VM proceeds to interpret the operations.

---

7. Interpretation of Operations

• The Virtual Machine interprets the assembler instructions step by step.

---

8. Final Output

• Upon successful execution, the program outputs the string: "Hello World!"

---

Error Handling Summary

• Errors can occur in two key stages:

  1. During file parsing

  2. During Virtual Machine parsing

• In both cases, the system gracefully terminates and displays an appropriate error message.

---

This structured workflow ensures that errors are detected early, enabling efficient debugging and reliable execution.
