Configuration

Simple yet powerful

Define your tasks in a clean YAML file. No complex syntax, no build system knowledge required.

babfile.yml
vars:  app_name: myapp  version: "1.0.0"
env:  APP_NAME: ${{ app_name }}
tasks:  dev:    desc: Start development server    deps: [setup]    run:      - prompt: port        type: number        message: Enter dev server port        default: 3000      - cmd: npm run dev -- --port ${{ port }}
  build:    desc: Build the application    deps: [setup]    vars:      target: release    run:      - log: ${{ app_name }} v${{ version }}      - cmd: go build -o app        dir: ./dist      - log: Done!        level: info
  setup:    desc: Install dependencies    env:      CI: "true"    run:      - cmd: ./install.sh        platforms: [darwin, linux]      - cmd: install.bat        platforms: [windows]
  deploy:    desc: Deploy to production    run:      - prompt: confirm_deploy        type: confirm        message: Deploy to production?      - task: build        when: ${{ confirm_deploy }} == 'true'      - cmd: ./deploy.sh        when: ${{ confirm_deploy }} == 'true'        env:          TARGET: production

Variables

Define vars at global or task level. Reference them anywhere with ${{ var_name }} syntax.

Task Composition

Reference other tasks with task: to compose complex workflows from simple building blocks.

Task Dependencies

Define deps and bab automatically runs prerequisites first. No more manual ordering.

Environment Variables

Set env vars at global, task, or command level. More specific levels override broader ones.

Platform-Specific Commands

Different commands for different operating systems. Write once, run anywhere.

Log Messages

Add informational log messages with levels: debug, info, warn, error.

Interactive Prompts

Collect user input during task runs. Supports confirm, input, select, multiselect, password, and number.

Working Directory

Set execution directory at global, task, or command level. Relative paths resolve from the Babfile location.

Conditional Execution

Skip tasks or commands based on conditions. Works with prompt results for dynamic workflows.

Run your tasks:

$babdev# Start dev server
$babbuild# Build the application
$babsetup# Install dependencies
$babdeploy# Deploy to production
$bab# Interactive mode
