Conda
Conda is a binary package manager, cross-platform environment manager, and dependency resolution engine. It serves as a software repository manager that enables the installation and update of pre-compiled binaries and their dependencies across different operating systems.
The system creates isolated execution spaces to prevent dependency conflicts between projects and uses a solver to calculate compatible package versions based on constraints from available repositories. It supports the creation of custom software packages from recipes, which can be hosted in public or private channels for distribution.
The project covers the full software lifecycle, including package indexing, searching, and cache maintenance. It provides tools for exporting reproducible environment specifications and tracks environment state revisions to allow for atomic rollbacks. Additionally, the tool includes package integrity verification and a plugin framework for integrating custom logic into the workflow.
Features
- Isolated Environment Managers - Provides isolated execution spaces with specific software versions to prevent dependency conflicts between projects.
- Project-Specific Shell Isolation - Creates independent execution spaces with specific software versions to prevent dependency conflicts between projects.
- Binary Package Managers - Serves as a comprehensive manager for installing and updating pre-compiled software binaries and their dependencies.
- Isolated Execution Environments - Sets up sandboxed execution environments with specific software versions to avoid dependency conflicts.
- Environment Specifications - Generates reproducible environment specification files in YAML or JSON formats for sharing and recreation.
- Environment Managers - Manages isolated runtime environments and binary dependencies across different operating systems.
- SAT-Based Solvers - Utilizes a SAT-based solver to resolve compatible package versions based on complex dependency constraints.
- Package Installers - Downloads and installs binaries and required dependencies from configured channels to a local system.
- Shell Environment Managers - Updates shell session path variables and functions to activate specific isolated software environments.
- Software Package Repositories - Enables building custom software packages from recipes and hosting them in public or private channels.
- Binary and Source Installation - Downloads and installs pre-compiled binaries and their dependencies across different operating systems.
- Dependency Resolution Engines - Analyzes complex dependency trees and constraints to calculate a compatible set of package versions.
- Environment Reproducibility Tools - Ensures software setups are reproducible across different systems through the export and import of environment specs.
- SAT-Based Dependency Resolution - Calculates a compatible set of package versions based on constraints using SAT-based solver backends.
