The CLI class encapsulates the behavior of capistrano when it is invoked as a command-line utility. This allows other programs to embed Capistrano and preserve its command-line semantics.
Create a new CLI instance using the given array of command-line parameters to initialize it. By default, ARGV is used, but you can specify a different set of parameters (such as when embedded cap in a program):
require 'capistrano/cli' Capistrano::CLI.parse(%W(-vvvv -f config/deploy update_code)).execute!
Note that you can also embed cap directly by creating a new Configuration instance and setting it up, The above snippet, redone using the Configuration class directly, would look like:
require 'capistrano' require 'capistrano/cli' config = Capistrano::Configuration.new config.logger.level = Capistrano::Logger::TRACE config.set(:password) { Capistrano::CLI.password_prompt } config.load "config/deploy" config.update_code
There may be times that you want/need the additional control offered by manipulating the Configuration directly, but generally interfacing with the CLI class is recommended.
