Not Allowing Input

[Bilal Aslam]

Well i'm trying to make a program for newbie practice and, in the while
loop at the bottom, i am not allowed to put in any information when i
run it. Can anyone help me out? Thanks

[src]
#!/usr/bin/ruby


sim_outorder_path = "/home/software/simplescalar/bin/sim-outorder"

puts "Welcome to the sim-outorder configuration utility."

# Put output name into script_name and remove the '\n'
puts "Enter script output name."
script_name = gets
script_name.chomp

# simplesim holds the names of and default values of the parameters
default_options =
{

"fastfwd" => "300000",
"max:inst" => "2000000",

# "config" => nil,

"res:ialu" => "4",
"res:imult" => "1",

}

# Initialize user_options
user_options = ""

# Print the defaults and ask for changes
default_options.each_key do |key|

# Show the option_name and the default value
puts key.to_s + "\tDefault = " + default_options[key].to_s
puts "Type 'd' to use default value"

# Get the option_value or d

# Set to " " to allow while loop to work
option_value = " "

# While user input is nothing
while option_value == ""
option_value = gets.chomp.to_s
end

if option_value.to_s == "d"
# Use default value
user_options += "-" + key.to_s + " " + default_options[key].to_s + "
"
else
# Use given value
# user_options += "-" + key.to_s + " " + option_value + " "
end

end

[/src]

Thanks a bunch That fixed my problem .

Just to be clear, when getting input from a while loop i should always
do

variable = gets.chomp

instead of

variable = gets
variable.chomp

or w/e operation im doing to the variable right?

Or it *could* be script_name = script_name.chomp, since #chomp is
non-destructive.

So, if should be anything, it should be script_name.chomp!
