directory structure for your JSON parser project in Golang:

json-parser/
|-- lexer/
|   |-- lexer.go
|-- parser/
|   |-- parser.go
|-- builder/
|   |-- builder.go
|-- main.go
|-- go.mod
|-- go.sum

Let's briefly describe the purpose of each directory and file:

json-parser/: Root directory of your project.

This directory contains the entire project. lexer/: Directory for the lexical analysis part.

lexer.go: Implementation of the lexer. parser/: Directory for the syntactic analysis (parser) part.

parser.go: Implementation of the parser. builder/: Directory for building JSON objects.

builder.go: Implementation of the object builder. main.go: Main entry point of your application.

This is where you can invoke the JSON parsing functionality. go.mod and go.sum: Files for managing Go modules.

These files help manage the project's dependencies.

1. Lexer (Tokenization): Design Approach: Define Token Types:

Enumerate the different types of tokens in JSON (e.g., string, number, boolean, null, object start, object end, array start, array end, comma, colon). Lexer Structure:

Create a lexer structure that takes an input string and produces a stream of tokens. Use a state machine or regular expressions to match and identify token patterns. Token Structure:

Define a Token structure with fields like Type (enumeration) and Value (actual value of the token).

2. Parser (Syntactic Analysis): Design Approach: Define Grammar Rules:

Enumerate the grammar rules for JSON. Describe the hierarchical structure and relationships between different elements. Parser Structure:

Create a parser structure that takes a stream of tokens and produces an Abstract Syntax Tree (AST). Implement recursive descent parsing or another parsing technique based on the defined grammar. AST Structure:

Define a set of AST node types representing different elements of the JSON structure. Each node should have a type, value, and children (sub-nodes).

3. Builder (Constructing Golang Objects): Design Approach: Traverse AST: Create a function that traverses the AST and converts it into corresponding Golang objects.

4. Main Entry Point: Design Approach: Integrate Lexer, Parser, and Builder: Create a main entry point that orchestrates the entire process: tokenization, parsing, and building JSON objects.
