(Emacs)~config->app,core

Browse Source 
The two largest sections of my config are separated into their own
files now.  Does increase init time, but I just can't handle how big
this thing is.  It'll be a bit nicer to look at and manage with
separate files.

#+title: Applications for Emacs

Applications are greater than packages; they provide a set of
functionality to create an interface in Emacs. Emacs comes with
applications and others may be installed.
* WIP Dashboard
:PROPERTIES:
:header-args:emacs-lisp: :tangle no
:END:
Dashboard creates a custom dashboard for Emacs that replaces the
initial startup screen in default Emacs. It has a lot of customising
options.
Unfortunately not that useful, many things are easier to invoke
directly such as recent files or project changing.

* EWW
Emacs Web Wowser is the inbuilt text based web browser for Emacs. It
can render images and basic CSS styles but doesn't have a JavaScript
engine, which makes sense as it's primarily a text interface.

Calendar is a simple inbuilt application that helps with date
functionalities. I add functionality to copy dates from the calendar
to the kill ring and bind it to "Y".
#+begin_src emacs-lisp

#+end_src
* Mail
Mail is a funny thing; most people use it just for business or
advertising and it's come out of use in terms of personal
communication in the west for the most part (largely due to "social"
media applications). However, this isn't true for the open source and
free software movement who heavily use mail for communication.
Integrating mail into Emacs helps as I can send source code and
integrate it into my workflow just a bit better.

* Xwidget
Xwidget is a package which allows for the insertion of arbitrary
xwidgets into Emacs through buffers. It must be compiled into Emacs
so you might need to customise your install. One of its premier uses
is in navigating the web which it provides through the function
~xwidget-webkit-browse-url~. This renders a fully functional web
browser within Emacs.
Though I am not to keen on using Emacs to browse the web /via/ xwidget
(EWW does a good job on its own), I am very interested in its
capability to render pages with JavaScript, as it may come of use when
doing web development. I can see the results of work very quickly
without switching windows all within Emacs.

** Xwidget Extensions
Define a function ~+xwidget/render-file~ that reads a file name and
presents it in an xwidget. If the current file is an HTML file, ask
if user wants to open current file. Bind it to ~aU~ in the leader.
Also define a function ~+xwidget/search-query~ that first asks the
user what search engine they want to use ([[https://duckduckgo.com][Duck Duck Go]] and [[https://devdocs.io][DevDocs]]
currently) then asks for a query, which it parses then presents in an
xwidget window. Bind to ~as~ in the leader.

* Eshell
** Why Eshell?
Eshell is an integrated shell environment for Emacs, written in Emacs
Lisp. I argue that it is the best shell/command interpreter to use in
Emacs.
Eshell is unlike the alternatives in Emacs as it's a /shell/ first,
not a terminal emulator. It has the ability to spoof some aspects of a
terminal emulator (through the shell parser), but it is NOT a terminal
emulator.
The killer benefits of eshell (which would appeal to Emacs users) are
a direct result of eshell being written in Emacs lisp:
- incredible integration with Emacs utilities (such as ~dired~,
~find-file~, any read functions, to name a few)
- very extensible, easy to write new commands which leverage Emacs
commands as well as external utilities
- agnostic of platform: "eshell/cd" will call the underlying change
directory function for you, so commands will (usually) mean the same
thing regardless of platform
- this means as long as Emacs runs, you can run eshell
However, my favourite feature of eshell is the set of evaluators that
run on command input. Some of the benefits listed above come as a
result of this powerful feature. These evaluators are described below.
Lisp evaluator: works on braced expressions, evaluating them as Lisp
expressions (e.g. ~(message "Hello, World!\n")~). Any returned
objects are printed. This makes eshell a LISP REPL!
External evaluator: works within curly braces, evaluating them via
some external shell process (like sh) (e.g. ~{echo "Hello,
world!\n"}~). This makes eshell a (kinda dumb) terminal emulator!
The alias evaluator is the top level evaluator. It is the main
evaluator for each expression given to eshell. When given an
expression it tries to evaluate it by testing against these conditions:
- it's an alias defined by the user or in the ~eshell/~ namespace of
functions (simplest evaluator)
- it's some form of lisp expression (lisp evaluator)
- it's an external command (bash evaluator)
Essentially, you get the best of both Emacs and external shell
programs *ALL WITHIN* Emacs for free.
** Eshell functionality
Bind some evil-like movements for easy shell usage, and a toggle
function to pull up the eshell quickly.
#+begin_src emacs-lisp
(use-package eshell
:commands +shell/toggle-eshell

(recenter))
"k" #'eshell-kill-process))))
:config
(+oreo/create-toggle-function
+shell/toggle-eshell
"*eshell*"
eshell
t))
#+end_src
** Eshell pretty symbols and display
Pretty symbols and a display record.
#+begin_src emacs-lisp
(use-package eshell
:defer t
:pretty
(eshell-mode-hook
("lambda" . "λ")
("numberp" . "ℤ")
("t" . "⊨")
("nil" . "Ø"))
:display
("\\*e?shell\\*" ; for general shells as well
(display-buffer-at-bottom)
(window-height . 0.25)))
#+end_src
** Eshell variables and aliases
Set some sane defaults, a banner and a prompt. The prompt checks for
a git repo in the current directory and provides some extra
information in that case (in particular, branch name and if there any
changes that haven't been committed).
Also add ~eshell/goto~, which is actually a command accessible from
within eshell (this is because ~eshell/*~ creates an accessible
function within eshell with name ~*~). ~eshell/goto~ makes it easier
to change directories by using Emacs' find-file interface (which is
much faster than ~cd ..; ls -l~).
#+begin_src emacs-lisp
(use-package eshell
:config
(defun +eshell/get-git-properties ()
(let* ((git-branch (shell-command-to-string "git branch"))

"Use `read-directory-name' to change directories."
(eshell/cd (list (read-directory-name "Enter directory to go to:")))))
#+end_src
** Eshell change directory quickly
~eshell/goto~ is a better ~cd~ for eshell. However it is really just
a plaster over a bigger issue for my workflow; many times I want
eshell to be present in the current directory of the buffer I am
using.
#+begin_src emacs-lisp

* Calculator
Surprise, surprise Emacs comes with a calculator.
Greater surprise, this thing is over powered. It can perform the
following (and more):
- Matrix calculations
- Generalised calculus operations
- Equation solvers for n-degree multi-variable polynomials
- Embedded mode (check below)!
~calc-mode~ is a calculator system within Emacs that provides a
diverse array of mathematical operations. It uses reverse polish
notation to do calculations (though there is a standard infix
algebraic notation mode).
Embedded mode allows computation with the current buffer as the echo
area. This basically means I can compute stuff within a buffer
without invoking calc directly: $1 + 2\rightarrow_{\text{calc-embed}} 3$.
#+begin_src emacs-lisp

#+end_src
** WIP Calctex
:PROPERTIES:
:header-args:emacs-lisp: :tangle no
:END:
~calc-mode~ also has a 3rd party package called ~calctex~. It renders
mathematical expressions within calc as if they were rendered in TeX.
You can also copy the expressions in their TeX forms, which is pretty
useful when writing a paper. I've set a very specific lock on this
repository as it's got quite a messy work-tree and this commit seems to
work for me given the various TeX utilities installed via Arch.

2023-08-17: `Man-notify-method' is the reason the `:display' record

Packages that are absolutely necessary for the rest of the
configuration. These yield core functionality such as keybinding,
modal editing, completion, auto typing to name a few.
* General
General provides a great solution for binding keys. It has evil and
use-package support so it fits nicely into configuration. In this
case, I define a "definer" for the "LEADER" keys. Leader is bound to
~SPC~ and it's functionally equivalent to the doom/spacemacs leader.
Local leader is bound to ~SPC ,~ and it's similar to doom/spacemacs
leader but doesn't try to fully assimilate the local-leader map,
instead just picking stuff I think is useful. This forces me to learn
only as many bindings as I find necessary; no more, no less.
I also define prefix leaders for differing applications. These are
quite self explanatory by their name and provide a nice way to
visualise all bindings under a specific heading just by searching the
code.

* Evil
My editor journey started off with Vim rather than Emacs, so my brain
has imprinted on its style. Thankfully Emacs is super extensible so
there exists a package (more of a supreme system) for porting Vim's
modal editing style to Emacs, called Evil (Emacs Vi Layer).
However there are a lot of packages in Vim that provide greater
functionality, for example 'vim-surround'. Emacs, by default, has
these capabilities but there are further packages which integrate them
into Evil.
** Evil core
Setup the evil package, with some opinionated keybindings:
- Switch ~evil-upcase~ and ~evil-downcase~ because I use ~evil-upcase~
more
- Switch ~evil-goto-mark~ and ~evil-goto-mark-line~ as I'd rather have
the global one closer to the home row
- Use 'T' character as an action for transposing objects

** Evil collection
Provides a community based set of keybindings for most modes in
Emacs. I don't necessarily like all my modes having these bindings
though, as I may disagree with some. So I use it in a mode to mode basis.
#+begin_src emacs-lisp
(use-package evil-collection
:after evil)
#+end_src
* Completion
Emacs is a text based interface. Completion is its bread and butter
in providing good user experience. By default Emacs provides
'completions-list' which produces a buffer of options which can be
searched and selected. We can take this further though!
Ido and Icomplete are packages distributed with Emacs to provide
greater completion interfaces. They utilise the minibuffer to create
a more interactive experience, allowing incremental searches and
option selection.
Ivy and Helm provide more modern interfaces, though Helm is quite
heavy. Ivy, on the other hand, provides an interface similar to Ido
with less clutter and better customisation options.
** Ivy
Ivy is a completion framework for Emacs, and my preferred one. It has
a great set of features with little to no pain with setting up.
*** Ivy Core
Setup for ivy, in preparation for counsel. Turn on ivy-mode just
after init.
Setup vim-like bindings for the minibuffer ("M-(j|k)" for down|up the
selection list).

Ido is a very old completion package that still works great to this

similarly to a fully fledged completion framework.

** Amx
Amx is a fork of Smex that works to enhance the

* Pretty symbols
Prettify symbols mode allows for users to declare 'symbols' that
replace text within certain modes. Though this may seem like useless
eye candy, it has aided my comprehension and speed of recognition
(recognising symbols is easier than words).
Essentially a use-package keyword which makes declaring pretty symbols
for language modes incredibly easy. Checkout my [[C/C++][C/C++]] configuration
for an example.
#+begin_src emacs-lisp

* Window management
Emacs' default window management is quite bad, eating other windows on
a whim and not particularly caring for the current window setup.
Thankfully you can change this via the ~display-buffer-alist~ which
matches buffer names with how the window for the buffer should be
displayed. I add a use-package keyword to make ~display-buffer-alist~
records within use-package.
I have no idea whether it's optimal AT ALL, but it works for me.

* Auto typing
Snippets are a pretty nice way of automatically inserting code. Emacs
provides a ton of packages by default to do this, but there are great
packages to install as well.
Abbrevs and skeletons make up a popular solution within Emacs default.
Abbrevs are for simple expressions wherein the only input is the key,
and the output is some Elisp function. They provide a lot of inbuilt
functionality and are quite useful. Skeletons, on the other hand, are
for higher level insertions
The popular external solution is Yasnippet. Yasnippet is a great
package for snippets, which I use heavily in programming and org-mode.
I setup here the global mode for yasnippet and a collection of
snippets for ease of use.
** Abbrevs
Just define a few abbrevs for various date-time operations. Also
define a macro that will assume a function for the expansion, helping
with abstracting a few things away.

~use-package~ keyword ~auto-insert~ which allows one to define an
entry for ~auto-insert-alist~.
