Quick Start

use code2prompt_core::{Code2PromptConfig, Code2PromptSession};
 
let config = Code2PromptConfig::builder()
    .path(&temp_dir)
    .build()?;
 
let mut session = Code2PromptSession::new(config);
let output = session.generate_prompt()?;
println!("Generated {} tokens", output.token_count);

Main Components

• Code2PromptConfig - Configuration and builder
• Code2PromptSession - Main workflow orchestrator
• template - Template processing and rendering
• filter - File filtering and selection
• git - Git repository integration

Modules

analysis

Analysis Engine for Codebase Statistics

builtin_templates

Built-in templates embedded as static resources.

configuration

This module defines the Code2PromptConfig struct and its Builder for configuring the behavior of code2prompt in a stateless manner. It includes all parameters needed for file traversal, code filtering, token counting, and more.

file_processor

File processor module for handling different file types intelligently.

filter

This module contains pure filtering logic for files based on glob patterns.

git

Git repository integration for diff extraction and branch operations.

path

This module contains the functions for traversing the directory and processing the files.

selection

This module contains the SelectionEngine that handles user file selection with precedence rules.

session

This module defines a Code2promptSession struct that provide a stateful interface to code2prompt-core. It allows you to load codebase data, Git info, and render prompts using a template.

sort

This module provides sorting methods for files and directory trees.

template

Template system for customizable prompt generation.

tokenizer

This module encapsulates the logic for counting the tokens in the rendered text.

util

This module contains util functions
