Feature for putting output back into vim

[xdl]

Loving using this plugin, although I was wondering if there's an easy way to send the results of the evaluation back into the vim buffer automatically? I'm using this with tmux at the minute and am finding that switching over to the tmux pane, copy the output, switching back to paste it in getting a bit tedious.

Hi there,

"easy way" … I don't think so, unless I've missed something. When we paste text to tmux, it just flushes it in the input buffer (as if you had typed it yourself)… but what happens (the feedback) is a result of whatever is running.

I can imagine doing a snapshot before, a snapshot after, and diff both -- taking that as the "result" of the command you just ran. I'm not sure how easy/hard that would be … or whether it would be useful at all.

In what context do you need to copy the result back in vim? (maybe there are other ways)

Ah I see, yeah there weren't any easy ways that came to my mind either.

I have a ipython session pane open alongside a vim pane in tmux, and I've gotten into the habit of pasting the results of snippets of python evaluations back into vim to remind me of how I developed a function (kind of like really lazy tdd).

Maybe wrapping the contents of what you send into tmux with a session (bash, ipython, ghci etc.) specific callback that sends the output back to tmux to give back to the vim pane? Does that sound like something that might work - I don't mind spending some time looking into this if you think it's plausible!

You can feed and read back a command with the system(…) function. If you do that, you need to feed enough context to run… it's a new process every time. I mean: feed the function and feed the invocation, both.

It's similar to what happens when you select a block of text and feed it to python:

print 1 + 2   # shift-v select, !python,  => 3

Hmm do you think there might be a way to preserve the environment of the interpreter (e.g. previously defined variables etc.) between system calls?

no, not really :-(
