prompt for command-line input

[drewda]

In the set of deploy scripts I currently use for most Rails projects I have Capistrano prompt for a password to insert into the database.yml file that will go on the server.

Here's the tutorial I originally followed: http://www.simonecarletti.com/blog/2009/06/capistrano-and-database-yml/ and here's the Cap command: Capistrano::CLI.ui.ask("Enter MySQL database password: ")

Before attempting to build a helper method like this for Mina I figured I'd just ask if anyone else has attempted this or has other preferred methods of getting passwords into config files.

(By the way, a big thanks to the folks who have been working on Mina. It's such a clean and well-documented library in comparison with Capistrano!)

I'm not sure how this can fit into:

It generates an entire procedure as a Bash script and runs it remotely in the server.

All you need is probably

puts 'Enter MySQL database password: '
passwd = gets.strip

@stas is correct, you may even want to try the highline gem for password input.

Thank you, @stas and @rstacruz! I'll give your suggestions a try.

The highline gem works well, as in the following example:

require 'highline/import'
ask "PostgreSQL password:" do |password|
    queue! %Q{sudo -u postgres psql -c "create user #{psql_user} with password '#{password}';"}
    queue! %Q{sudo -u postgres psql -c "create database #{app_name} owner #{psql_user};"}
end
