Task
Task is a YAML-based task runner and build tool used to define and automate development workflows. It functions as a dependency-based build system and cross-platform task automator, allowing users to execute shell commands across different operating systems using a declarative configuration file.
The project operates as an incremental build tool, utilizing file fingerprints and checksums to track state and avoid redundant work by determining if tasks are up to date. It manages execution via a dependency graph to ensure prerequisites are completed before target commands run.
The system includes capabilities for parallel task execution, environment variable management, and dynamic variable resolution. It provides standardized file operations and supports the inclusion of external task configurations to modularize workflows. Additional functionality covers conditional execution, data-driven looping, and file change monitoring.
Features
- Cross-Platform Build Systems - Provides a cross-platform build system for running consistent command sequences across different operating systems.
- Build Task Runners - Provides a command-line tool for automating development workflows and build processes via declarative configuration files.
- YAML Configuration Files - Uses declarative YAML configuration files to define tasks, variables, and dependency relationships.
- Development Workflow Automators - Automates repetitive coding tasks like linting and testing through a centralized YAML configuration file.
- Fingerprint-Based Freshness Tracking - Tracks file fingerprints and checksums to skip redundant work and implement incremental builds.
- Dynamic Variable Evaluators - Calculates variable values at runtime using shell commands or template functions.
- Environment Variable Templating - Implements dynamic variable expansion and template resolution within task properties and commands.
- Incremental Build Systems - Tracks file fingerprints and checksums to avoid redundant work by only executing modified tasks.
- Named Task Orchestration - Executes specific named tasks and manages variable passing and output visibility.
- Task Dependency Management - Defines a graph of prerequisites that must complete before a target task is executed.
- Execution State Hashing - Calculates unique hashes based on run policies to determine if a task should be executed or skipped.
- YAML-Based Task Definitions - Uses declarative YAML files to define named tasks, variables, and conditional execution logic.
- Environment Variable Configurations - Injects runtime settings and configuration parameters into tasks via key-value environment variables.
- Dependency Graph Orchestrators - Uses a dependency graph orchestrator to manage execution sequences and ensure prerequisites are completed.
- Environment Variable Management - Loads configuration from dot-env files and manages environment variable precedence for commands.
- Directed Acyclic Graph Engines - Implements a dependency-based execution engine using directed acyclic graphs to ensure correct task ordering.
- File System Monitoring - Watches files or directories and automatically triggers associated tasks upon modification.
- Iterative Task Execution - Iterates through matrices of values or lists of files to execute commands repeatedly.
- Platform-Specific Task Restrictions - Prevents specific tasks from running if the current operating system or architecture does not match requirements.
- File System Operations - Provides built-in utilities for common file operations to ensure consistent behavior across different operating systems.
- Conditional Task Execution - Skips task execution based on shell exit codes, template expressions, or platform-specific constraints.
- Task Execution Sequencing - Provides coordination of tasks into parallel execution paths to reduce total execution time.
- Cross-Platform Compatibility - Runs different commands based on the operating system or architecture to ensure cross-platform compatibility.
- Standardized Project Command Sets - Creates a standardized set of project commands to simplify onboarding and environment setup for contributors.
- Modular Task Configurations - Supports importing external task configurations from local paths or remote repositories to modularize workflows.
- Task Precondition Configurators - Runs shell commands as preconditions and blocks task execution if these commands fail.
- Concurrency Controllers - Limits the number of simultaneous process executions via semaphores to prevent system resource exhaustion.
- Concurrent Task Limiters - Controls the number of concurrent tasks to manage system resource consumption during parallel execution.
- Cross-Platform Abstractions - Provides an abstraction layer that maps generic file operations to native shell commands across different operating systems.
- Build and Compilation Tools - Task runner and build automation tool.
- Build Automation - Simple alternative to the Make build tool.
- Developer Tools and CLIs - Fast, cross-platform build tool.
- Developer Utilities - A task runner and build tool as an alternative to Make.
- General Utilities - Task runner as a Make alternative.
- General Utility Libraries - Task runner as a Make alternative.
