Is there a simpler way to do the following?
<code>
Person = Struct.new( :first_name, :last_name )
print "Enter first name: "
first_name = gets.chomp.capitalize
print "Enter last name: "
last_name = gets.chomp.capitalize
p = Person.new( first_name, last_name )
printf "Hello %s %s.\n", p.first_name, p.last_name
</code>
My idea was to create a function the prints a message and then takes
console output. What I want to do is not have to create the extra
objects for first and last name. Below is the solution I can up with.
<code>
def pgets( msg )
print msg
gets
end
Person = Struct.new( :first_name, :last_name )
p = Person.new(
pgets( "Enter first name: " ).chomp.capitalize,
pgets( "Enter last name: " ).chomp.capitalize
)
printf "Hello %s %s.\n", p.first_name, p.last_name
</code>
Thanks,
Shane
HighLine makes this kind of thing pretty simple:
Neo:~/Desktop$ ls
person.rb
Neo:~/Desktop$ ruby -rubygems person.rb
Name? (last, first) Gray, James
--- !ruby/struct:Person
first_name: James
last_name: Gray
Neo:~/Desktop$ cat person.rb
#!/usr/local/bin/ruby -w
require "highline/import"
require "yaml"
class Person < Struct.new(:first_name, :last_name)
def self.parse( input )
if input =~ /^\s*(\w+),\s*(\w+)\s*$/
self.new($2, $1)
else
raise ArgumentError, "Invalid name format."
end
end
end
who = ask("Name? (last, first) ", Person)
y who
__END__
Hope that helps.

Not to shanghai this convo (but its sort of on the same subject), is there a
way to prompt for a response in-line with your question rather than printing
the question and then having it go to the next line?

Thanks James that's a really nice solution.
Yes, either set $stdout.sync = true, or call $stdout.flush.

The HighLine example I posted does exactly that. The space at the end of the question is a hint to HighLine that I'll take the answer on the same line.

Neither seem to be required:
$ ruby -e 'print "Name? "; gets; puts "Hello #$_"'
Name? James
Hello James
Ruby is a pretty clever girl.
