ruby dev.el
Pry enters arena to compete with SLIME!
cd ~/.emacs.d
git clone https://github.com/Mon-Ouie/ruby-dev.el
cat >> init.el <<EOT
(add-to-list 'load-path "~/.emacs.d/ruby-dev.el" )

With those config lines above, whenever you edit some Ruby code (or M-x turn-on-ruby-dev
), it will enable the ruby-dev
minor mode.
Note that it is very new, so it might have some rough edges.
Starting simple, there's C-c C-s
. Press that then say: 5+3
.
In the minibuffer, at the bottom, you'll see an 8
.
As soon as you do any code evaluation, a Ruby process will start inside Emacs with which the editor can communicate (via JSON).
Next, type:
(("le.ved-ybur"*50).reverse)
Then hit C-c C-e
(or C-x C-e
).
The parens are here because this will evaluate the "Ruby sexp" (the unit of
which is visible by pressing C-M-b
and C-M-f
to hop around.)
Also possible is C-x C-b
to evaluate the whole buffer, or C-x C-r
to
evaluate the marked region (e.g., marked with C-Space
).
Use C-c C-i
(Ctrl+c, Tab) to enter a REPL session. (rking is having an issue
with this where the buffer comes up empty. If you replicate, please let us
know on Freenode #pry.)
Notice how the context of the evaluations from before are present in this
session. This is because the process, ruby-dev
, is the one that runs
Pry.start
. If for some reason you want to restart this process, you can run
M-x ruby-dev
C-c C-d
to get an navigable ri
interface!
To see all keybindings, do:
C-x C-h
To see info about the internal functions, try:
C-h a ruby-dev RET
