I have been using rspec-mode to run my specs lately.
It’s nice to get the spec feedback without having to tab out to a terminal (or
running a terminal in emacs).
C-c ,m works great, it runs
all the specs for the current buffer. More and more, I’ve been seeing the value
in Magit-mode. I always loved the ease in which magit lets
you choose hunks of files to commit, but I just learned that you can
stage arbitrary sections of a hunk! Simply mark (highlight) the section
that you want to stage for commit, and then press
magit-status-mode. So handy!
However, after a computer restart nothing seemed to work
correctly. Magit-mode was complaining that
it couldn’t find the git executable. I had recently moved Apple’s
/usr/bin/git2 so that the system
would use Homebrew’s version of git (I upgraded because of a
vulnerability found in git clients). Turns out that my PATH variable
for emacs was messed up. For future reference, the ‘path’ variable in
emacs is called ‘exec-path’. PATH = exec-path. Took me way too
long to figure that out. The exec path wasn’t including
/usr/local/bin/, the directory that homebrew puts all
it’s executables (or at least symlinks them there). The fix for this
was as simple as evaluating
exec-path) in an elisp scratch buffer. A more permanent fix was
to add this to my ‘platform-specific.el’ file in my emacs.d:
1 2 3 4 (if (eq system-type 'darwin) ... ;; add homebrew (/usr/local/bin) to the exec path (push "/opt/local/bin" exec-path))
The error that I was seeing for rspec-mode was something like
your ruby version is 2.0.0 but your gemfile specified
I eventually realized that the command being run in the rspec-compilation
bundle exec rspec spec/path/to/specs/run.
Before I had been seeing
spring rspec spec/path/to/specs.
spring rails server or any other spring command 1
in a terminal started up spring properly.After that rspec mode seemed to know
to use spring to run the rspec commands, which solved the ruby
version dependency. This could probably be solved properly via some RVM
or RVM.el configuration, but hey, my specs run nicely now!
Spring is a rails application preloader that makes your specs and other rails commands run much faster, and is included in rails 4. github.com/rails/spring ↩
