Read Only Buffers On compilation

Read Only Buffers On compilation

[flebber]

I seem to have an odd behaviour when executing scripts in emacs. The
scripts work fine if no input is required. But when input is required
the compilation buffer is read-only. How can I make the buffer read-
write so that input can be taken. So for example a very basic script
asking for input such as below would work in emacs.

puts "What Directory do you want"
STDOUT.flush
file = gets.chomp
Dir.foreach("C:/"[file])  do |entry|
  puts entry
end

C-h f compile RET says:

  [...]
  Additionally, with universal prefix arg, compilation buffer will be in
  comint mode, i.e. interactive.

So try C-u M-x compile RET

I don't know how to do what you ask.

Usually on GNU/Linux programs are compiled by using batch files that
don't require interactive input, they are configured either by editing
some files, or by passing command line arguments, or by setting some
environment variables.

Interactive text-mode programs usually are started from within the
shell, either from inside the shell-mode buffer `M-x shell RET' or from
an external terminal.

Cool, did not know that.

Another alternative, use echo to provide standard input.
