Unfortunately spacemacs is not designed for installation
at use-package call time.
For use-package to be called a package must already be installed,
so I will continue on the initial plan, that is providing the
quelpa recipe at the <layer>-packages list level.
This is no bigdeal, this is basically moving :quelpa from
use-package to <layer>-packages variables.
Moreover it makes more sense to define package property at
declaration time instead of initialization (at least in spacemacs
world where installation is decoupled from configuration).
This has a benefit of not assuming that the user .emacs.d/ is in the
user home directory. Should continue to work as expected when this is
the case, but you could also start a fresh Emacs session like
so (assumes OSX):
open -a Emacs.app -n --args -q -l /path/to/emacs.d/init.el
So you don't have to muddle with symlinking your ~/.emacs.d or replacing
it with another just to try Spacemacs (or any other config). Note, that
this won't work with `after-init-hook` which doesn't appear to run when
Emacs is run with -q flag. As a result the `dotspacemacs/config` in your
.spacemacs won't run.
`tooltip-use-echo-area' is obsolete since 24.1; disabling `tooltip-mode'
achieves similar effect, and Tooltip mode has already been disabled in the
current code. Since Spacemacs supports Emacs 24.3 and 24.4,
`tooltip-use-echo-area' usage can be removed safely.
Not sure why that part of code was introduced in the first place but it seems to no longer work with the newest
packages. Both backtick and quote behaviors were a kind of broken. Removing the code makes them normal again. And there
seems to be nothing wrong with Github code blocks.
I have seen many "I have a problem" discussions in the Gitter chat which
starts with a barrage of questions "Which OS? Which Emacs version?",
etc., so I thought it may be useful to have one function that will
generate the info to be copy-pasted into the Gitter chat and hence both
the user and others helping in the Gitter chat can jump directly to
solving the problem instead of the support volley to figure out the
setup.
Example output:
ELISP> (spacemacs/system-info)

The ess company sources should be grouped, when they are not grouped
they are pretty buggy (like not showing completions under certain
circumstances).
To see the problem, try opening an R file and start the interpreter.
When you type the following ([] is the cursor):
setN[]
You will see completions offering up `setNames`. Press `<enter>`.
Now, try doing the following:
setNames(setN[])
You will see no completions. Company is trying the `company-R-args`
source, failing it, then skipping the execution of the
`company-R-objects` source.
Grouping them together fixes this, and is what's done within ess itself.
