This page is a personal memo in a university lecture
A tool that allows you to create CLI commands. It seems that git etc. are also developed with this. thor's GitHub is here
First, put what you need
gem install bundler gem install thor
bundle gem <CLI command name> -b
hoge.gemspec in the created directory with an editor and rewrite the part that is TODO appropriately.
Give permission, install
chmod a+x exe/hoge bundle install
Write the command processing program in
lib/hoge.rb. For example, ↓
require 'thor' require "hoge/version" class HogeCLI < Thor desc "hoge NAME", "Say hello to NAME" def hello(name) puts "Hello " + name end end HogeCLI.start(ARGV)
desc is the explanation that is displayed when you do
hoge help. The
hoge NAME part represents a command input example, and the
Say hello to NAME part represents a description of the command. The class name must end with
Once the program is complete
bundle update bundle install
bundle exec exe/hoge
You can execute the created command with.
To make the created command available from anywhere
But I was angry without rubocop, so
gem install rubocop
I tried it again after putting it in.
Now from anywhere
hoge hello fuga
You can now call it with.
It seems to be something like ruby's code formatter. I wonder if it corresponds to flake8 in python & # x2026 ;?
If you do, it will show you where to fix the code.
rubocop --auto-correct hoge.rb
Then, it seems that it will be corrected automatically.
