I could be mistaken, but isn't this a GNU Readline feature?

Neat regardless.

I think this is different because I'm full on opening an instance of vim. (I didn't know about GNU Readline though and it looks awesome - I'll definitely try and work it into a project at some point).

Either Readline let's you do the same, or that is just a bash specific feature I am miss remembering. I can check later when I'm not on my phone.

I'm only using GNU readline for my bash prompt, but if I press v it spawns a full-on $EDITOR instance to edit the commandline.

IPython has this feature baked in the magic %ed command [1].

Yes, and to edit the last thing you typed, you can run %ed _. When you exit %ed it runs the code and then returns the code as a string.

This is awesome! I really should learn iPython one of these days...

Cool.

Haven't looked at the code yet, but I wrote:

https://github.com/Julian/dotfiles/blob/master/.config/pytho...

which does something similar (and is interpreter agnostic as it looks like this is).

philipbjorgeOP13y ago

Mine's not interpreter agnostic because I had to mess with the stack frames to insert variables into the global context.

But yours is able to do that because your importing a top-level edit function while I was pretty set on dynamically creating a vim() method and not having to import a function (just a module).

I love how yours lists the globals though! I might just have to bite that feature :).

JulianWasTaken13y ago

Oh, yeah, well, importing stuff on interpreter startup is pretty much exactly what $PYTHONSTARTUP is for :).

IPython can also be run as a server (ipython kernel[1]) and then connected to via a vim plugin called vim-ipython [2]. This means you can do the other direction: evaluate a vim buffer in a running IPython session, and then connect to that IPython session to actually use the code you wrote in vim.

Nice. Reminds me of a feature I have in Glass Table[0]:

Define a procedure, macro, or record type called foo:

    (define (foo x) ...)

Now say:

    ,(edit foo)

Your definition appears in the editor of your choice. (Try running GT within Emacs and setting your EDITOR to "emacsclient".) Make changes; provided no errors occurred (like missing parens) the changes take effect when you save and quit.

It's a nice little workflow; if you squint, it almost feels like a CADR...

For Ruby IRB, there is interactive editor: http://vimcasts.org/episodes/running-vim-within-irb/
