Hello,

I use [1] to process a string from cmdline-user-input to call methods
form a module namespace. It works for
now, but there are later a lot of commands to input so i want
tab-completion because iam lazy

module CmdsBase
CmdsBase.cmd_foo
DoSomething.new
end

...
end

All methods with /^cmd_(\w*)$/ should be completeable from
commandline.

Any ideas to solve this clean?

[1]
# snip:
def self.cmd
begin

line = gets
args, i =[], -1
line.scan(/\w*\s/) do |a|
a.strip!
meth = nil
unless (i+=1).zero? and

MyBiadjCmdlineCaller.methods.include?(a)
break if i.zero?
args.push(a)
else
meth = a
end

unless args.size.zero? # ignoring input with arguments yet
MyBiadjCMDLine.ok?(MyBiadjCmdlineCaller.method(meth).call)
end

end
end while true
end





So long

Have you tried using the Readline module?

require "readline"
$completions = ["cmd_1","cmd_42","cmd_one"]
Readline::completion_proc = Proc.new{ |prefix| $completions if prefix
=~ /cmd_/ }
0.upto(4) { line = Readline::readline( "Cmd? ", true ) }

You get the idea...

Daniel.

require "readline"
$completions =3D ["cmd_1","cmd_42","cmd_one"]
Readline::completion_proc =3D Proc.new{ |prefix| $completions if prefix
=3D~ /cmd_/ }
0.upto(4) { line =3D Readline::readline( "Cmd? ", true ) }
