It's meant to be loaded from init.el like so:

2019-04-05 14:05:40 +00:00

#+END_SRC
2019-04-23 15:30:19 +00:00
Requires:
#+BEGIN_SRC emacs-lisp

* Default directory
#+BEGIN_SRC emacs-lisp

#+END_SRC
2019-01-28 02:46:29 +00:00
* Packages
Set up package.el to load from ELPA and MELPA
#+BEGIN_SRC emacs-lisp

#+END_SRC
`use-package` is a macro that simplifies installing and loading packages. `use-package-always-ensure` makes sure that all packages will be installed before loading is attempted.
#+BEGIN_SRC emacs-lisp

* Benchmarking
`benchmark-init` does what it says on the box. This sets it up to benchmark my init time and then disable benchmarking after init completes.

`exec-path-from-shell` uses Bash to set MANPATH, PATH, and exec-path from those defined in the user's shell config. This won't work on Windows.

* Autocompletion
There seems to be [[https://github.com/company-mode/company-mode/issues/68 ][some contention ]] about whether autocomplete or company are better autocomplete packages. I'm going with company for now because the maintainer seems nicer...
