Go tool for formatting, checking, building, distributing and publishing projects

gödel

gödel is a Go build tool that provides tasks for configuring, formatting, checking, testing, building and publishing Go projects in a declarative, consistent and reproducible manner across different platforms and environments. gödel can be used in both local development environments and for verifying the correctness of project in CI environments. gödel uses declarative configuration to define the parameters for a project and provides an executable that orchestrates build tasks using standard Go commands. It centralizes project configuration and eliminates the need for custom build scripts that conflate configuration with logic. gödel is designed to be portable, fast and lightweight -- adding it to a project consists of copying a single file and directory into the project and adds less than 50kb of version-controlled material.

gödel is also highly extensible and configurable. The core functionality of gödel is provided by plugins and assets, and it is easy to write new plugins or assets and to configure a gödel instance to use custom plugins or assets as needed.

Features

The following features are provided by a default gödel installation (either as builtin tasks or default plugin tasks):

• Add to a project by running the godelinit program
• ./godelw git-hooks installs Git commit hook that formats files on commit
• ./godelw goland creates and configures a GoLand project for the project
• Supports configuring directories and files that should be excluded by the tool
• ./godelw format formats all code in a project
• ./godelw check runs a variety of code linting checks on all the code in a project
  • Default configuration includes a wide variety of checks that catch common errors
  • Custom checks can be added as assets
• ./godelw license applies a specified license header to all Go files in a project
  • Supports configuring custom license headers for specific directories or files
• ./godelw test runs the tests in the project
  • Configuration can be used to define test sets (such as integration tests) and run specific test sets
  • Supports outputting the test results in a JUnit XML format
• ./godelw build builds executables for main packages in the project
  • Supports cross-platform compilation
  • Supports configuration of ldflag for version and other variables
  • Installs packages by default to speed up repeated builds
• ./godelw dist creates distribution files for products
  • Supports creating tgz distributions
  • Supports customizing creation of distribution using scripts
  • Supports creating custom distributions using assets
• ./godelw publish publishes artifacts to Bintray, Artifactory or GitHub
  • Supports other forms of publishing using assets
• palantir/godel/pkg/products package provides a mechanism to easily write integration tests for gödel projects
  • Provides a function that builds the product executable or distribution and provides a path to invoke it
• ./godelw update updates gödel to the version specified in godel/config/godel.properties
• ./godelw verify runs all of the tasks that declare support for verification
  • Can be used locally as a single command to apply changes and run checks
  • Can be used in CI to verify that a project is in the proper state without applying changes
• ./godelw github-wiki mirrors a documents directory to a GitHub Wiki repository

This list is not exhaustive -- run ./godelw --help for a list of all of the available commands. Furthermore, custom
