Saving code written during an irb session

Output irb history to named file

def dumphist(path=“irb.log”)
File.open(path, ‘w’) do |file|
Readline::HISTORY.each do |line|
file.puts line unless /^\s*dumphist/ =~ line
end
end
end

dummier question: Now, how do I load a (script) file to irb (history)?

My initial wants:

  1. I’d like to load & unload scripts in irb.
  2. I’d like/dream to combine irb, -rdebug, and ri together…

liken to what Chad said, I’d like a textual ide :slight_smile:

Hmm, I’ve seen posts on how to run a script and then have
it stop in irb so you could continue interactively. I don’t
know where, just do a google search. It should not be hard
to find.

I’ve also seen ri added to irb. Of course, you could add a simple
function to .irbrc like this

def ri(query)
puts ri #{query}
end

then just do

ri “Array.shift”

liken to what Chad said, I’d like a textual ide :slight_smile:

You may want to search for what has been done with
vim and emacs.

Try:

def loadhist(path)
File.open(path) do |io|
io.each do |line|
Readlines::HISTORY << line
end
end
end

I don’t know if that will work, or if it’s even possible.

That’s a dead end, AFAIK. You can’t really interact with your program
much - no local variables. For anyone who’s interested, though, it’s
worth a try for yurself; you may find something interesting.

I’d like what Botp wants as well. Vim and emacs have some potential,
but FreeRIDE is more likely, just because it’s the focal point of
efforts to produce IDE functionality. It’s a shame that the editor
must be implemented when there are two great ones right there, but
that’s life. Vim and emacs both have very impractical “extension”
languages.
