使用thor作为复杂的命令行工具

Question

i want to create a command line tool in Ruby using Thor. This tool should be packaged as a gem so that it is easily installed and uninstalled.

Creating and publishing the gem, I have done. I also created several Thor scripts which also work. However, I do not know how to combine them.

My aim is to be able to call my tool the following way: mytool task param --options mytool taskgroup:task param --options

I know how to make one Thor script to be executable. However, how do I make a bunch of thor scripts accessible throw one command?

Answer 1

According to the relevant Gem documentation , you could specify (in your .gemspec):

spec.executables = ['bin/foo', 'bin/bar']
spec.default_executable = 'bin/bar'

and have your gem install a bunch of executables ( foo and bar ). Or you write a wrapper for all your Thor scripts and specify:

spec.executables = ['bin/wrapper']

and have your gem install only one executable ( wrapper ).

The teletype gem ( https://github.com/piotrmurach/tty ) does an amazing job at setting up all the scaffolding for this. Create your project with teletype and then just fill in the implementation.
