An extensible, friendly framework for project go scripts.

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

In your project root:

curl -fsSL "https://raw.githubusercontent.com/Bestowinc/dot-slash-go/HEAD/.go/core/vendor" | bash -s -- init

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 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.

./go core vendor and ./go core update uses git subtree to vendor git repositories including dot-slash-go itself, the vendored git directories are defined in .go/.git-vendor:

Core dot-slash-go functionality commands

Usage:
  ./go core update
  ./go core vendor (add|list|remove|update) [options]

Commands:
  update     runs `./go core vendor update dot-slash-go` from root directory
  vendor     adds, lists, removes, or updates a vendored git repository

./go core update will pull changes from the upstream dot-slash-go repo defined in .go/.git-vendor

This is based on these projects:

• Bash CLI
• git-vendor

Some changes include

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

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
   init
   # Do command-specific work
