问题
I have a thor-based Ruby script, but I want to deploy it as a gem in people's bin
directories that people can hit without having to do thor mytool
.
So instead they'd just use mytool
Is this possible?
I know it's possible with vanilla optparse
but I'd rather use Thor if possible.
Update: This is the code I'm using based on the example on the Thor page, but I get the error below:
#!/usr/bin/env thor
class App < Thor
map "-L" => :list
desc "install APP_NAME", "install one of the available apps"
method_options :force => :boolean, :alias => :string
def install(name)
user_alias = options[:alias]
if options.force?
# do something
end
# other code
end
desc "list [SEARCH]", "list all of the available apps, limited by SEARCH"
def list(search="")
# list everything
end
end
Error:

回答1:
Make the shebang line
#!/usr/bin/env ruby
and then at the end of your script add
App.start

I wanted to have a thor-based executable for a gem, with namespaced subcommands, but organize the task files according to the normal ruby gem lib/mygem/*/.rb structure.
回答3:
Make the script executable
chmod +x mytool
and make #!/usr/bin/env thor
the first line in mytool
.
