Submodules

Remember to also clone submodules:

git clone --recursive git@github.com:bryangarza/dot-emacs.git

Paredit

• Paredit Cheatsheet
• Another Paredit Cheatsheet

Org mode

• The Org Manual
• The compact Org-mode Guide
• Org-mode Tutorial / Cheat Sheet

Org-present

• left and right for movement
• C-c C-= for large text
• C-c C-- for small text
• C-c C-q to quit (which will return you back to vanilla org-mode)
• C-c < to jump to first slide
• C-c > to jump to last slide

Hydras

• C-c m Hydra for all hydras
• C-c w Window movement and manipulation
• C-c c Multiple cursors
• C-c o Org mode headings
• C-c a Avy

Zooming

• C-x C-+ and C-x C-- (‘text-scale-adjust’) to increase or decrease the buffer text size
• C-+ or C-- to repeat
• C-x C-0 to restore the default (global) face height
• S-mouse-1 pops up a menu where you can choose these same actions

Eyebrowse

The default key bindings are:

Key bind	Function
C-c C-w <	Switch to previous window config
C-c C-w >	Switch to next window config
C-c C-w ’	Switch to last window config
C-c C-w ”	Close current window config
C-c C-w ,	Rename current window config
C-c C-w 0	Switch to window config 0
…	…
C-c C-w 9	Switch to window config 9

I also bound all the s-<n> keys to switch to that window config. Which you can do with another eyebrowse function but that one also sets some other keys I don’t want to override, so I just did it manually.

Don’t feel like putting this in a table…. From (eyebrowse-setup-evil-keys)

(define-key evil-motion-state-map (kbd "gt") 'eyebrowse-next-window-config)
(define-key evil-motion-state-map (kbd "gT") 'eyebrowse-prev-window-config)
(define-key evil-motion-state-map (kbd "gc") 'eyebrowse-close-window-config)
(define-key evil-motion-state-map (kbd "zx") 'eyebrowse-last-window-config))

Steps to Install Coq and Proof General

brew install coq

…and set coq mode for coq files, done in config already. company-coq auto installs with use-package. Download the devel version of Proof General. Unpack the .tgz file. Recompile for current Emacs:

make clean; make compile EMACS=/usr/local/Cellar/emacs-mac/emacs-24.5-z-mac-5.15/Emacs.app/Contents/MacOS/Emacs

Make sure the right file path for the downloaded version of Proof General is in the config. (proof-site.el)

Unbinding

This will make the symbol my-nasty-variable’s value void:

(makunbound 'my-nasty-variable)

This will make the symbol my-nasty-function’s function definition void:

(fmakunbound 'my-nasty-function)

Pinning

If I ever want to pin packages:

(setq 'package-archives '(("melpa"        . "http://melpa.org/packages/")
                          ("melpa-stable" . "http://stable.melpa.org/packages/")))

(use-package company
  :ensure t
  :pin melpa-stable)

Helm

• Helm home page
• Helm intro

Aligning Code

Haskell wiki: aligning code in Emacs

(bind-key "C-x a r" 'align-regexp)

Editing with Sudo

C-x C-f /sudo::/path/to/file

Keybindings

Most of the keybindings I have set can be found in (bryan/keybindings). The majority involve the Super key, which on Mac is the Command key. On Windows or GNU/Linux, this is probably your Win key, but if it’s not bound, then just bind it!

Updating submodules

git submodule foreach git pull origin master

Finding face under point

what-cursor-position with a prefix argument shows the face under point, among other information.

Keyboard shortcut is C-u C-x =.

Ad-handle-definition warnings

To suppress things like

ad-handle-definition: `org-latex-keyword' got redefined

Do:

(setq ad-redefinition-action 'accept)

I didn’t though, because they are harmless, and I’d rather know when something is being advice’d.

OCaml

OCaml settings require external installation, see Real World OCaml’s GitHub wiki. If you don’t care about OCaml, simply comment out bryan/ocaml in bryan/pkg-full.

Graphical vs Console Emacs

Use Graphical Emacs.

Internal Notes

Because I keep forgetting the Org mode formatting:

You can make words *bold*, /italic/, _underlined_, =verbatim= and ~code~, and,
if you must, ‘+strike-through+’. Text in the code and verbatim string is not
processed for Org mode specific syntax, it is exported verbatim.
