latex list
Written by Daniel Herber on January 7, 2015 (last updated on March 17, 2017).
Throughout my usage of the $\LaTeX$ language, I have found a number of packages and commands essential to creating superb documents. Here I provide a list of my most commonly used $\LaTeX$ packages and commands. I use this page as a starting point for my documents; whatever is necessary for the particular document is copied into the preamble from the webpage.

### My Packages
Packages are grouped into 2 categories: simple and document modifying. Simple packages typically provide commands that can be used if warranted in your document while document modifying packages permanently change some aspect of the document when included. For example, the hyperref package cross-referencing with hyperlinks and by default the hyperlinks are created.
```tex
% simple packages
\usepackage[export]{adjustbox} % for image frames
\usepackage{algorithm2e} % environment for writing algorithms
\usepackage{amsmath} % AMS mathematical facilities
\usepackage{amssymb} % extended symbol collection and fonts
\usepackage{amsthm} % theorem-like structures
\usepackage[american]{babel} % cul-tur-ally de-ter-mined ty-po-graph-i-cal rules
\usepackage{blindtext} % produces text for testing
\usepackage{bm} % advanced bold symbols
\usepackage{calc} % perform arithmetic on the arguments of commands
\usepackage{caption} % makes captions ragged right
\usepackage[strict]{changepage} % change the page layout in the middle of a document

\usepackage[noadjust]{cite} % grouped citations
\usepackage{draftwatermark} % watermarks
\usepackage{hyperref} % cross-referencing with hyperlinks
```
#### My Package Options
Next are the package options. Some are more general such as setting the page layout with the geometry package while others are specific such as formating the watermark in the draftwatermark package. Similar to the packages, the package options are grouped by simple and document modifying.
```tex

### My Commands
Finally here are some custom commands. Required packages are noted.
```tex
% commands
\newcommand{\overbar}[1]{\mkern 1.5mu\overline{\mkern-1.5mu#1\mkern-1.5mu}\mkern 1.5mu} % alternative to \bar{} command
\newcommand{\la}{\left\langle} % shorthand dot product
\newcommand{\ra}{\right\rangle} % shorthand dot product
\newcommand{\myline}{\begin{center}\line(1,0){200}\end{center}} % centered horizontal line
\newcommand{\progr}[1]{\textsc{#1}\texorpdfstring{$^\circledR$}{}} % better registered trademark, requires amsmath, amssymb, and hyperref packages
\newcommand{\cmark}{\ding{51}} % check mark, requires pifont package
\newcommand{\xmark}{\ding{55}} % x-like mark, requires pifont package
\newcommand{\doi}[1]{\mbox{doi: \href{http://doi.org/#1}{#1}}} % digital object identifier hyperlink, requires hyperref package
```
