Hi All:
Forgive me in advance for this stupid request:
How can I make irb work
from this:
------------------
irb(main):015:0> 1
=> 1
irb(main):016:0> 2+2
=> 4
irb(main):017:0>
irb(main):018:0> 5.times{p "hello ruby"}
"hello ruby"
=> 5
------------------
to this:
------------------
1 #=> 1
2+2 #=> 4
5.times{p "hello ruby"} #"hello ruby"
#"hello ruby"
#=> 5
------------------
iow,
1. I want to remove the prompt char
2. I want output of irb not to be placed right below, but right next at a
certain column (so that output aligns)
3. I want the output prefixed w # char (easy for cut & paste)
thanks in advance

A partial answer is:
$ irb --prompt-mode xmp
1 + 2
==>3
5-3
==>2
For more information read man irb
As i see it, it is not possible to get the output on the line. Maybe also investigate the emacs xmp package.
regards,
Brian

Customizing prompt
To costomize the prompt you set a variable
IRB.conf[:PROMPT]
For example, describe as follows in `.irbrc'.
IRB.conf[:PROMPT][:MY_PROMPT] = { # name of prompt mode
:PROMPT_I => nil, # normal prompt
:PROMPT_S => nil, # prompt for continuated strings
:PROMPT_C => nil, # prompt for continuated statement
:RETURN => " ==>%s\n" # format to return value
}
Then, invoke irb with the above prompt mode by
$ irb1.8 --prompt my-prompt
Or add the following in `.irbrc'.
IRB.conf[:PROMPT_MODE] = :MY_PROMPT
Constants PROMPT_I, PROMPT_S and PROMPT_C specifies the format. In the prompt specification, some special strings are available.
%N command name which is running
%m to_s of main object (self)
%M inspect of main object (self)
%l type of string(", ', /, ]), `]' is inner %w[...]
%NNi indent level. NN is degits and means as same as printf("%NNd").
It can be ommited
%NNn line number.
%% %
For instance, the default prompt mode is defined as follows: IRB.conf[:PROMPT_MODE][:DEFAULT] = {
PROMPT_I => "%N(%m):%03n:%i> ",
PROMPT_S => "%N(%m):%03n:%i%l ",
PROMPT_C => "%N(%m):%03n:%i* ",
RETURN => "%s\n"}
RETURN is used to printf.
