Include Split — Split Taskfile.yml into Multiple Files

Rozbicie dużego Taskfile.yml na mniejsze pliki za pomocą include.

Structure

project/
├── Taskfile.yml              # Main file — includes + local overrides
├── tasks/
│   ├── build.yml             # Build tasks + variables
│   ├── deploy.yml            # Deploy tasks + environments (prefix: deploy)
│   └── test.yml              # Test/lint tasks
└── README.md

How include Works

# Taskfile.yml
include:
  - path: ./tasks/build.yml             # Merge tasks as-is
  - path: ./tasks/deploy.yml
    prefix: deploy                       # Tasks become: deploy-local, deploy-staging, deploy-prod
  - path: ./tasks/test.yml              # Simple string path also works

Merge Rules

1. Tasks — included first, local Taskfile wins on conflict
2. Variables — included first, local wins
3. Environments — included first, local wins
4. Prefix — optional, prepends {prefix}- to included task names

What Gets Merged

Section	Merged	Local Wins
tasks	✅	✅
variables	✅	✅
environments	✅	✅
pipeline	❌ (main only)	—
compose	❌ (main only)	—

Usage

# All included tasks are available as if defined locally
taskfile list
taskfile run build                # from tasks/build.yml
taskfile run test                 # from tasks/test.yml
taskfile run lint                 # from tasks/test.yml
taskfile run deploy-local         # from tasks/deploy.yml (prefixed)
taskfile run deploy-staging       # from tasks/deploy.yml (prefixed)
taskfile run deploy-prod          # from tasks/deploy.yml (prefixed)
taskfile run all                  # local task, depends on included tasks

# Validate (includes are resolved during parsing)
taskfile validate

Include Formats

# String shorthand
include:
  - ./tasks/build.yml

# Dict with path
include:
  - path: ./tasks/build.yml

# Dict with prefix
include:
  - path: ./tasks/deploy.yml
    prefix: deploy

# Dict with file (alias for path)
include:
  - file: ./tasks/test.yml

When to Split

• Monorepo — each service has its own tasks file
• Shared tasks — common CI/test tasks reused across projects
• Team separation — infra team owns deploy.yml, dev team owns build.yml
• Large Taskfile — >100 lines → split by concern
