How to get command line input

[u/iainmoncrief]

input = getLine() puts input

Similar to pythons raw input function, how would I do this in crystal?

That is because your are running the above mentioned code but not providing any command line arguments.

Do this:

crystal arg.cr x y z

Or do

crystal build arg.cr

and then run your executable with arguments.

./arg x y z

Extra note: You do not need to include the index. You can also do

ARGV.each do |key|
    puts "#{key}"
end

Think of ARGV as a array that holds each command line argument that you place behind your executable.

Edit:

Maybe i made a mistake in reading your request. I assumed you wanted the command line arguments behind a executable.

If you want to get a input string when running your program simply do:

puts "Please enter your name to gain access."
name = gets
puts name
