Usage

Running the task file requires a shell alias: alias task='./task'

Show the available commands with task help.

From the specification the project can be installed with task install.

Execute all commands with task all.

Completion

With the output of task help the task commands can be completed.

Completion for bash: /etc/bash_completion.d/task_completions

#!/usr/bin/env bash

_task_completions() {
    local cur prev commands
    cur="${COMP_WORDS[COMP_CWORD]}"
    prev="${COMP_WORDS[COMP_CWORD-1]}"

    commands=$(./task help | grep -A999 -e '---' | awk '{print $2}' | sed 's/^[[:space:]]*//' | grep -v '^$' | tr '\n' ' ')

    if [[ ${COMP_CWORD} == 1 ]]; then
        COMPREPLY=( $(compgen -W "${commands}" -- "${cur}") )
    elif [[ ${COMP_CWORD} == 2 ]]; then
        COMPREPLY=( $(compgen -f -- "${cur}") )
    else
        COMPREPLY=()
    fi
}

complete -F _task_completions task
complete -F _task_completions t

Completion for zsh: ~/.oh-my-zsh/completions/_task

#compdef task t

_arguments '1: :->tasks' '*: :_files'

case "$state" in
    tasks)
        args=$(./task help | grep -A999 -e '---' | awk '{print $2}' | sed 's/^[[:space:]]*//' | grep -v '^$' | tr '\n' ' ')
        args="$args help"
        _arguments "1:profiles:($args)"
        ;;
esac

The completion also works for task alias alias t='./task'.

See taskfile.build/image for details.

Integration

The task file is intended to be integrated into the shell setup. Whenever an applicatio uses a domain specific language (DSL) ensure that the DSL calls the task file. Most you'll see DSLs to describe build pipelines.

GitHub Actions

Running task file commands in GitHub Actions is highly recommended. This way you can run the same CI/CD procedures in the GitHub runner as you do on your localhost.

The GitHub Actions config is simple: .github/workflows/build.yml

on:
    pull_request:
        branches:
            - 'main'
    push:
        branches:
            - 'main'

jobs:
    build:
	    name: Build
        runs-on: ubuntu-latest
        steps:
	        - name: Checkout
	          uses: actions/checkout@v4
			- name: Clone taskfile
			  run: ./task clone-taskfile
		    - name: Install uv
		      uses: astral-sh/setup-uv@v6
            - name: Install
              run: ./task install
            - name: Lint
              run: ./task lint

Jenkins

Run task file commands in Jenkins: Jenkinsfile

pipeline {

    agent any

    stages {
        stage('version') {
            steps {
                script {
                    currentBuild.description = sh (script: 'git log -1 --pretty=%B', returnStdout: true).trim()
                }
                sh './task version'
            }
        }
        stage('install') {
            steps {
                sh './task install'
            }
        }
        stage('lint') {
            steps {
                sh './task lint'
            }
        }
    }
