# NARF Emacs
> What we do every night, Pinky...
This is an Emacs configuration for stubborn vimmers and megalomaniacal mice alike. It
strives to emulate vim as best it can, and surpass it in any way possible.
It is tailored to my needs as an software developer (app, game, and web), data scientist,
and writer running OSX and Emacs **24.5+**.
## Installation
```
brew install cask
brew tap railwaycat/emacsmacport
brew install emacs-mac --with-imagemagick --with-modern-icon
git clone --depth 1 https://github.com/hlissner/emacs.d ~/.emacs.d
cd ~/.emacs.d
make # installs plugins via cask and generates autoloads
```
And to optionally:
```
make compile # optionally byte-compiles everything
make snippets # install hlissner/emacs-snippets into private/snippets
```
## Features
To get a picture of what's in here, check out:
* **[The Caskfile](Cask)**: lists installed plugins and where they're configured.
* **[init.el](init.el)**: lists all loaded modules
* **[private/my-bindings.el]**: most of the custom keybinds
* **[private/my-commands.el]**: available custom ex commands
### Basic
* Modal editing with **evil-mode**
* Pretty line numbers with **nlinum** and neckbearded hackery
* Syntax checking with **Flycheck**
* Completion with **company-mode**
* Pretty mode-line with **spaceline**
* Project navigation with **helm** and **neotree**
* Session persistence (and tab emulation) with **workgroups2**
* Run code inline with **quickrun**
* On-demand REPLs for many major modes with **repl-toggle**, including Ruby, Python,
PHP, JS, Elisp, and Lua.
* 2-char searching with **evil-snipe**
* Display diffs in the margin with **git-gutter**
* Repeat (most) motions with SPC
* Snippet expansion with **yasnippet**
* File template support with **auto-insert** and **yasnippet**
* Code folding with **hideshow**; doesn't allow arbitrary folds though
* Multiple cursors with **[evil-multiedit]**
* O/S interaction functions, like **os-reveal** and **os-open-in-browser**
* Custom TODO, FIXME and NOTE highlighting
* **big-mode** for presentations and demonstrations
* Tmux integration with `:t` and `:tcd` ex commands
### Advanced
* **Popup control with Shackle**: I've (mostly) tamed window popups in Emacs with
Shackle (popwin was unstable and slow), that includes those made by: Helm,
vc-annotate, quickrun, neotree, \*messages\*, org-mode--and others.
* **Ex compatibility**: I've given quite a few plugins an Ex interface. For instance,
`:t [ARGS]` and `:tcd` for tmux, `:ag [KEYWORDS]` for helm-ag, and `:align [REGEXP]`
for align-regexp. See [private/my-commands.el] for more.
* **Incremental highlighting for `:g[lobal]`**: evil's stock global command does not
do this (`:align` will also highlight matches).
* **A multiple cursor implementation using iedit**: I could never get [evil-mc] working,
and [multiple-cursors] doesn't play nice with evil-mode, so I wrote [evil-multiedit].
To use it, hop into visual mode, select a region and press S-r (shift-R).
Your edits will apply to all highlighted regions. To limit iedit's scope: while in
iedit mode go into visual, select a range and press SPC.
* **Rudimentary support for extra =expand(...) symbols in evil-ex**: this includes
`%:[pdert]`, which can be used with ex commands like `:e`, `:w`, or in the expression
register. This *could* be truer to vim, but I haven't gotten around to it.
* **Vim-esque Omni-completion commands**: I've implemented most of the common
omni-completion shortcuts:
```
C-x C-l 'narf/company-whole-lines
C-x C-k 'narf/company-dict-or-keywords
C-x C-f 'company-files
C-x C-] 'company-tags
C-x s 'company-ispell
C-x C-s 'company-yasnippet
C-x C-o 'company-semantic
C-x C-n 'company-dabbrev-code
C-x C-p (lambda (interactive)
(let ((company-selection-wrap-around t))
(call-interactively 'company-dabbrev-code)
(company-select-previous-or-abort))))
```
* **Popup REPLs**: currently supports python (ipython), ruby (pry), php (boris),
elisp (ielm), lua, js (nodejs), and the shell. More support later, hopefully for go
and rust.
* **Yasnippet + auto-insert = file-templates with editable fields**: _and_ it works with
evil-mode! See [core/core-file-templates.el](core/core-file-templates.el) for
configuration details.
* **Tab emulation with Workgroups2**: Workgroups2 will display the tabs in the
minibuffer when you press ⌘-S-T, use `:tabs` or move between "tabs". `gt`
and `gT` work as well.
⌘-1 - ⌘-9 keybindings work as well.
* **Minimalistic mapping macro**: I liked how concise mapping keys in viml was. I
brought a little of that to Emacs by defining `map!`, a macro for defining keybindings
in as little space as possible. [See my bindings](private/my-bindings.el) for an
example.
* **Modeline improvements**
* **evil-search/iedit/evil-substitute mode-line integration**: I better integrated
Anzu, evil-search, evil-substitute (e.g. `%s/foo/bar`) and
[evil-multiedit](https://github.com/hlissner/evil-multiedit) into the mode-line.
* **Macro-recording indicator**:
* **Show (py|rb)env version in mode-line**: see `define-env-command!` on how to set it up
for other modes. It only displays in their respective major-modes.
