ADR-J Tool

Release Build Status License: MIT

A Java based command-line tool for working with Architecture Decision Records (ADRs). More information about what ADRs are and why to use them can be found in this article.

ADR-J is based on the script based tools from Nat Pryce. It has been extended so that custom ADR templates can be created.

Quick Start

Install ADR-J tool

Use the adr command to manage ADRs. Try running adr help.

ADRs are stored in your project as Markdown files in the doc/adr directory.

  1. Create an ADR directory in the root of your project:

     adr init doc/architecture/decisions

    This will create the first ADR recording that you are using ADRs to record architectural decisions and linking to Michael Nygard's article on the subject.

    To use a different template to the standard, specify the path of a template:

    adr init -t ~/standards/ doc/architecture/decisions

    A guide to writing templates can be found here.

  2. Create Architecture Decision Records

     adr new Implement as Unix shell scripts

    This will create a new, numbered ADR file and open it in your editor of choice (as specified by the VISUAL or EDITOR environment variable).

    To create a new ADR that supersedes a previous one (ADR 9, for example), use the -s option.

     adr new -s 9 Use Rust for performance-critical functionality

    This will create a new ADR file that is flagged as superseding ADR 9. It then opens the new ADR in your editor of choice.

    To create a new ADR that references another ADR, use the -l option.

    adr new -l 4:"Links to" Use JMS interface for messaging

    This will create a new ADR that references ADR 4 and inserts the message "Links to" in the new ADR.

  3. For further information, see the man pages or use the built in help:

     adr help
