Hi I am making a simple ruby script practiced where I make a form using gets.chomp
and arguments, the problem is that when gets.chomp
use the script returns me an error when I apply the argument test
.
The code:
#!usr/bin/ruby
def formulario(quien)
while (1)
print "[+] Word : "
word = gets.chomp
print quien + " -> " + word
end
end
quien = ARGV[0]
formulario(quien)
The error:
[+] Word : C:/Users/test/test.rb:8:in `gets': No such file or directory @ rb_sysopen - test (Errno::E
NOENT)
from C:/Users/test/test.rb:8:in `gets'
from C:/Users/test/test.rb:8:in `formulario'
from C:/Users/test/test.rb:17:in `<main>'
Can anyone help?
It looks like you want to the user to type some input by reading a line from STDIN
, the best way to do this is by calling STDIN.gets
and not gets
. So your line becomes:
word = STDIN.gets.chomp
This is documented as IO.gets
. STDIN
is an instance of IO
.
Right now, you're executing Kernel.gets
, which does something different (emphasis mine):
Returns (and assigns to $_) the next line from the list of files in ARGV (or $*), or from standard input if no files are present on the command line.
This appears to behave like STDIN.gets
if ARGV
is empty, but is not the same thing, hence the confusion.
