Directorygo

Introduction

DirectoryGo is a cross‑platform, command‑line directory management utility designed to streamline navigation, search, and metadata handling for local file systems. Developed in the Go programming language, DirectoryGo combines speed, reliability, and extensibility, making it suitable for both personal use and integration into larger automation workflows. The project was released under an open‑source license and is maintained by a community of contributors from around the world.

History and Development

Early Concepts

The idea for DirectoryGo emerged in 2019 when a small group of developers identified gaps in existing file‑system navigation tools. While utilities such as find, locate, and fd provide robust searching capabilities, they lack cohesive metadata management and fine‑grained access controls. The initial prototype focused on fast indexing of directory trees and exposing a consistent interface for querying file attributes.

Architecture and Design

Core Components

DirectoryGo is structured around four core components:

Indexer – Scans file systems and populates an internal SQLite database with file attributes and user‑defined tags.
Query Engine – Interprets user queries, applies filters, and retrieves results from the index.
CLI Layer – Provides command‑line access, formatting of output, and scripting hooks.
Plugin Manager – Enables third‑party extensions for additional functionality such as cloud integration or custom authentication.

Data Model

DirectoryGo stores metadata in a single SQLite database. Each file record contains standard attributes such as path, size, modification time, permissions, and MIME type. Additional columns accommodate user‑defined tags and encryption keys. The database schema is normalized to reduce duplication while maintaining query efficiency.

Plugin System

Plugins are compiled as shared objects (.so or .dll) and loaded at runtime. They must expose a simple API defined by the core package, allowing them to register custom commands, modify query behavior, or intercept file access events. The plugin system promotes modularity and facilitates integration with external services.

Key Features

DirectoryGo offers a succinct navigation syntax, enabling users to move between directories, list contents, and view file details with minimal keystrokes. The built‑in history feature tracks recent paths, allowing quick jumps back to previous locations.

Search Capabilities

Advanced search filters include wildcard patterns, regular expressions, size ranges, date constraints, and tag combinations. The query language supports logical operators (AND, OR, NOT) and grouping, enabling precise retrieval of files across large directory trees.

Metadata Management

Users can attach arbitrary key‑value tags to files and directories. Tags are stored in the index and can be queried or used to generate custom views. The tagging system integrates with the CLI, allowing inline assignment and bulk updates.

Access Control

DirectoryGo implements role‑based access controls (RBAC) at the file level. Permissions are defined in a JSON policy file and can be enforced through the CLI or plugins. This feature is particularly useful in multi‑user environments where file access must be regulated.

Cross‑Platform Support

Compiled binaries are available for Windows (64‑bit), macOS (Intel and Apple Silicon), and Linux (x86_64, ARM64). The tool abstracts platform‑specific details such as file permissions and path separators, presenting a uniform interface to the user.

Installation and Configuration

System Requirements

DirectoryGo requires a 64‑bit operating system with a recent version of Go installed for development builds. For binary releases, a minimum of 1 GB RAM and 200 MB free disk space are recommended to accommodate the SQLite index.

Installation Procedures

Binary Download – Users can download prebuilt binaries from the project's releases page.
Package Managers – The utility is available via Homebrew, Chocolatey, and apt‑get.
Source Build – Clone the repository and run go build ./cmd/directorygo to compile.

Configuration Options

DirectoryGo reads configuration from a YAML file located in ~/.config/directorygo/config.yaml. Settings include index location, default output format, authentication backends, and plugin paths. Users can override configuration values via command‑line flags.

Usage and Command Reference

Basic Commands

dirgo init – Initializes a new index in the current directory.
dirgo scan – Refreshes the index with the latest file system state.
dirgo ls – Lists directory contents with optional filtering.
dirgo find <pattern> – Searches for files matching a pattern.
dirgo tag <path> <key=value> – Assigns a tag to a file or directory.

Advanced Commands

dirgo filter – Applies complex query expressions to the index.
dirgo archive – Creates compressed archives of selected files.
dirgo sync – Synchronizes files with a remote repository via plugins.
dirgo audit – Generates logs of file access based on policy rules.

Scripting and Automation

The CLI supports piping and JSON output, allowing integration into shell scripts and CI/CD pipelines. Example: dirgo find *.txt | jq -r .path | xargs cp -t /backup. Users may also write custom scripts in Go that import the core library and embed DirectoryGo functionality into larger applications.

Integration with Other Systems

Directory Services

Plugins enable DirectoryGo to interact with LDAP, Active Directory, and other directory services for authentication and policy retrieval. These integrations provide seamless access control in enterprise environments.

Operating Systems

DirectoryGo can be configured to respect OS‑level permissions, such as Windows ACLs or POSIX file modes. The tool also adapts to different filesystem types, including NTFS, ext4, APFS, and Btrfs.

Third‑Party Applications

Common use cases involve integration with backup software, monitoring tools, and content management systems. The plugin architecture allows developers to expose DirectoryGo commands as APIs or command hooks for external systems.

Security Considerations

Authentication and Authorization

DirectoryGo supports multiple authentication backends, including local credential files, token‑based systems, and external OAuth providers. Authorization is enforced through RBAC policies that specify allowed actions for each role. These policies are evaluated on each command that accesses or modifies file metadata.

Encryption

Sensitive files may be encrypted using AES‑256 before being stored in the index. Encryption keys are managed by the plugin system, allowing integration with key‑management services such as HashiCorp Vault or AWS KMS.

Audit Logging

All file access events are recorded in a dedicated audit table within the SQLite database. Logs include timestamps, user identifiers, and action types, providing a traceable record for compliance audits.

Performance and Scalability

Benchmark Results

In a controlled environment, DirectoryGo indexed a 500‑GB dataset consisting of 12 million files in approximately 15 minutes on a quad‑core machine. Search queries returned results in sub‑second latency for typical patterns, with complexity scaling linearly with the number of indexed entries.

Optimization Techniques

DirectoryGo employs several strategies to maintain performance:

Incremental indexing to avoid full rescans.
Prepared statements and indexing in SQLite to accelerate queries.
Parallel traversal using Go's goroutine scheduler.
Optional compression of the SQLite database to reduce disk I/O.

Community and Development

Open Source Governance

The DirectoryGo project follows a meritocratic model, with core maintainers elected based on contribution history and peer recognition. Decision making is conducted through public GitHub discussions and issue discussions.

Contribution Guidelines

Contributors are encouraged to submit pull requests for new features, bug fixes, and documentation updates. The repository includes a comprehensive style guide, coding standards, and automated tests that must pass before merging.

Documentation

Limitations and Known Issues

Compatibility Issues

DirectoryGo currently does not support network‑mounted filesystems with inconsistent metadata, such as certain NFS or SMB shares. Users are advised to run the indexer on local storage or synchronize metadata externally.

Feature Gaps

While the plugin system is robust, there is no built‑in GUI component. Third‑party developers provide optional web interfaces that rely on the core API. The tool also lacks native support for encrypted filesystems like eCryptfs.
