dot-slash-go Build Status

An extensible, friendly framework for project go scripts.

dot-slash-go Example


  • Simple installation in existing projects
  • Easily extend with new commands
  • Autogenerated usage instructions


In your project root:

bash -c "$(curl -sS"


Project metadata can be tweaked and changed by simply modifying the following files in your .go directory.

  • .name should contain the name of your app, something like "My Awesome App"
  • .author is meant to contain your name (or the name of your company)
  • .version should contain the version of your app, you can automatically include this using git describe --tags > .go/.version
  • .help should be a short-ish description of what your app does and how people should use it. Don't worry about including help for every command here, or even a command list, Bash CLI will handle that for you automatically.

Adding Commands

dot-slash-go script commands are just a stock-standard script with a filename that matches the command name. These scripts are contained within your .go folder, or within nested folders there if you want to create a tree-based command structure.

For example, the script .go/test/hello would be available through ./go test hello. Any arguments passed after the command will be curried through to the script, making it trivial to pass values and options around as needed.

The simplest way to add a command however, is to just run ./go command create [command name] and have it plop down the files for you to customize.

Contextual Help

The dot-slash-go script provides tools which enable your users to easily discover how to use your command line without needing to read your docs (a travesty, we know). To make this possible, you'll want to add two extra files for each command.

The first, [command].usage should define the arguments list that your command expects to receive, something like NAME [MIDDLE_NAMES...] SURNAME. This file is entirely optional, leaving it out will have go present the command as if it didn't accept arguments.

The second, [command].help is used to describe the arguments that your command accepts, as well as provide a bit of additional context around how it works, when you should use it etc.

In addition to providing help for commands, you may also provide it for directories to explain what their sub-commands are intended to achieve. To do this, simply add a .help file to the directory.


This project is based on the excellent Bash CLI. Some changes were made to better fit the needs of a go script.

  • Consolidation of main logic to a single file
  • Removal of install/uninstall commands
  • Storage of commands and metadata in .go rather than app

Frequently Asked Questions

  1. Can I use dot-slash-go to run things which aren't bash scripts? Absolutely, dot-slash-go simply executes files - it doesn't care whether they're written in Bash, Ruby, Python or Go - if you can execute the file then you can use it with dot-slash-go.

  2. How can I define common variables, or utility functions? Place a dot-prefixed executable shell script in your .go folder such as .globals. Then, execute that script from your commands. For example:

    #!/usr/bin/env bash
    set -e
    . ".go/.globals"
    # Call a function defined in globals
    # Do command-specific work
