EmacsVterm

Better integration of Julia REPL with Emacs vterm terminal.

Installation

1. In Julia prompt type:

   julia> ]add EmacsVterm
   

2. Add the following to ~/.julia/config/startup.jl:

   atreplinit() do repl
       @eval using EmacsVterm
       # Optionally set EmacsVterm.options as you like (see below)
   end

3. Configure julia-repl to use the vterm backend by putting:

   (julia-repl-set-terminal-backend 'vterm)

   to your Emacs config.

Features

• You can jump between prompts in *julia* REPL buffers with C-c C-p and C-c C-n.

• Julia REPL informs Emacs about its working directory. Therefore, after changing directory in Julia, opening file in Emacs (e.g. C-x C-f) starts in that directory.

• Documentation (@doc ... invocation or C-c C-d in julia-mode buffers with julia-repl enabled) is shown in a separate Emacs buffer.

  To disable this functionality, run:

  EmacsVterm.options.markdown = false

  If you are not happy with where Emacs chooses to display the *julia-doc* buffer, you can configure it via a "display action". For example, the following piece of code in init.el ensures that if the *julia-doc* buffer is already shown somewhere, the same buffer is reused; otherwise, a right side window with an appropriate width will be created.

  (add-to-list 'display-buffer-alist '("\\*julia-doc\\*"
    			       (display-buffer-reuse-window display-buffer-in-side-window)
    			       (side . right) (window-width . 80)))

• Images can be shown in the *julia-img* Emacs buffer. This functionality is not enabled by default. Enable it with:

  EmacsVterm.options.image = true

• In addition to EmacsVterm.options, the whole Emacs-based Multimedia I/O can be disabled (resp. enabled) with:

  EmacsVterm.display_off()
  EmacsVterm.display_on()
