Install MacEmacs http://emacsformacosx.com/
Set up the command line: http://emacsformacosx.com/tips
Do the clone thing in the spacemacs guide. https://github.com/syl20bnr/spacemacs
Start spaceemacs and press return when asked about evil mode or emacs mode (you want evil)
Edit ~/.spacemacs
(nb the themes megapack produces a lot of messages)
dotspacemacs-configuration-layers

scala
git
osx
markdown
javascript
themes-megapack
;; --------------------------------------------------------

Save, and restart. Ensime will download
For spell checking: $ brew install aspell
Install SBT plugin:
edit ~/.sbt/0.13/plugins/build.sbt
add:
addSbtPlugin("org.ensime" % "ensime-sbt" % "0.1.5")
In your SBT project, run gen-ensime (generates a .ensime file)
Colours have meaning. Bottom right (and cursor): orange (default mode), green insert mode
space = global command key (the "leader key") e.g.,
- space b ... brings up list of comands to do with buffers
- space f ... bring up list of commands to do with f
- space f r - list of recent files
- space f S - save all buffers
- space w 2 - two column layout
- space 1 - switch to buffer 1 (or click in it.. buffer number is shown bottom right)
- space b d - close (delete?) the buffer
- space : - same as meta key on Emacs
Sample workflow:
- space w - (split window below) or space w / (split right)
- space f r (select recent file to edit)
In Emacs, edit a Scala file in your project. Ensime starts, should have syntax highlighting.
https://github.com/syl20bnr/spacemacs/tree/master/contrib/lang/scala
Ctrl-Click to jump to source See: http://ensime.github.io/
You must have a project/build.properties file
Then... space : sbt-start to start sbt Ctrl-n / p = go to next and previous errors

TODO:
- how to get hash key working on UK keyboard.
Usual / and ?, but <spc> sc to clear any persistent highlighting.
<n>G to jump to line n. Eg 121G
Ctrl-x Ctrl-+ and Ctrl-x Ctrl--
or
<spc> z x and then repeatedly as required use = (reset), + (increase), and - (decrease). Any other key to leave this mode.
E.g., put our cursor on cat below, do do
-
<spc> s e(switches to iedit mode, red) -
L (restrict to current line, excluding the word cat <- here)
-
S(substitute) dog ESC ESC (should replace cats with dogs)The cat sat on the cat by the cat
E.g., go to the < in <- f below. Press Ctrl-v, then down cursor to select the next line.
Go into insert mode by pressing I, tap space then ESC You have aligned the generators.
for { a <- f b <- g why <- h } yield a * b / why
edit .spacemacs file and in the config section at the endd add:
(add-hook 'before-save-hook 'delete-trailing-whitespace)
(global-linum-mode)
(setq tab-width 2)
;;; From http://stackoverflow.com/questions/24921390/how-to-get-emacs-to-automatically-load-and-save-desktop-from-initial-directory
(setq your-own-path default-directory)
(if (file-exists-p
(concat your-own-path ".emacs.desktop"))
(desktop-read your-own-path))
(add-hook 'kill-emacs-hook
`(lambda ()
(desktop-save ,your-own-path t)))
also set default theme:
dotspacemacs-themes '(subatomic256)
...or monochrome or whatever theme you want from the megapack
Ctrl-C Ctrl-C to reload
, = context sensitive key for commands in say scala
<spc> p t bring up file navigator thingy as buffer/window 0.
Changing working dir
Set working directory to your SBT project E.g.,
- space : cd
- type then right arrow to select and navigate, return to select a directory
@d6y have you tried to setup auto-completion?
