Re: [julia-users] Re: edit() with foreground emacs

OK, yeah, I had the same problem when I had EDITOR="emacs -nw", so that it 
didn't launch the GUI but just opened up in the terminal.

Maybe we should make an issue and ask that edit be made a little more 
clever.  In your case, it could perhaps detect that there isn't a windowing 
system available, and then use run instead of spawn.  And in my case, 
perhaps it could notice the -nw flag and use run instead of spawn.

(when I unset JULIA_EDITOR)
Base.editor() == ["emacs"]

That runs emacs until I exit it, at which time I am back at the Julia REPL.
That is what I want edit() to do.

Yes, that's the problem.  I want emacs to be invoked with run(), not with
spawn().  My JULIA_EDITOR=mvim (where mvim is a symbolic link to emacs)
kludge works, but it's a kludge.

I'm on Mac OS X with Julia 0.4.3.

The edit function is defined in interactiveutil.jl 
.

What is the output if you run this at the REPL:

Base.editor()

What happens if you do this at the REPL:

run(`emacs Makefile`)

If you notice in the definition of edit that I linked to, when the editor 
is emacs, it uses spawn instead of run.

My EDITOR is set to emacs.  I am connected to an Ubuntu system via ssh,
with no X Window System.  When I unset JULIA_EDITOR and run julia,

julia> edit("Makefile")
emacs: standard input is not a tty

Maybe that's what you mean by "console emacs"?

Are you running the X Window System?  If so, then running emacs in the
background would work.

[julia-users] Re: edit() with foreground emacs

[daniel . matz]

It seems to work for me.

What were you trying to set JULIA_EDITOR to when you were trying emacs? 
 Were you trying to use console emacs with emacs -nw?
