GoCard is a lightweight and efficient file-based spaced repetition system (SRS) designed for developers who appreciate working with plain text files and version control. Built in Go, GoCard utilizes Markdown files organized in directories to create a simple yet powerful flashcard system that enhances learning through the SM-2 spaced repetition algorithm.

Key Features

• File-Based Storage: Organize all flashcards as Markdown files for easy access and management.
• Git-Friendly Workflow: Seamlessly track changes, collaborate, and backup through version control.
• Terminal User Interface: Offering a distraction-free terminal interface for focused learning sessions.
• Markdown Support: Fully supports Markdown rendering, complete with syntax highlighting for coding.
• Cross-Platform Compatibility: Compatible with Linux, macOS, and Windows operating systems.
• Spaced Repetition Algorithm: Implementing the SM-2 technique for optimal learning efficiency.
• Real-time File Watching: Automatically detects changes to card files and reloads them in real time.
• Hierarchical Deck Navigation: Navigate through decks using efficient vim and emacs keybindings.
• Programming Features: Supports over 50 programming languages with syntax highlighting and a side-by-side diff view for code comparison.
• Detailed Session Statistics: Provides insights on learning progress, including stats from review sessions.

Quick Start Guide

To create a flashcard, set up a directory structure and follow this Markdown template:

---
tags: [algorithms, techniques, arrays]
created: YYYY-MM-DD
review_interval: N
---

# Card Title
## Question
What is the two-pointer technique in algorithms and when should it be used?

## Answer
The two-pointer technique is useful for:
- Sorted array operations
- Finding pairs with specific conditions
- String manipulation
- Linked list cycle detection.

After creating the card, run GoCard to start reviewing:

gocard ~/YourFlashcardsDirectory

Project Structure

GoCard follows a modular layout designed to facilitate maintainability and extensibility. Components are neatly organized into directories, allowing for improvements without disrupting existing functionality.

Enhanced Learning Experience

The review process is streamlined; cards due for review are loaded automatically, and users are prompted to rate their recall of each card. This enhances memory retention through tailored intervals based on performance. Additionally, GoCard's real-time synchronization enables effortless updates to flashcards, accommodating an uninterrupted learning experience.

By emphasizing code-centric learning, GoCard stands out with features specifically tailored for developers and learners alike, making it a valuable tool for mastering new concepts and programming technologies.
