 % CAVEAT: -> a warning concerning some compilation issues that may break your system in some situation
 % ADJUST: -> manual tweaks that you may want to change
 % TODO: -> to-do list
 % HACK: -> Savy macros to easily use a given packages

 %%%%%%%%% Document language %%%%%%%%%
 % \usepackage[utf8]{inputenc} % ADJUST: descomente esta linha para mudar o idioma do texto para Português
 % \usepackage[portuguese]{babel}
 % \usepackage{cmap} % must be loaded before fontenc; embeds a proper ToUnicode CMap so copy-pasted text from the PDF isn't garbled
 % \usepackage[T1]{fontenc} % single-glyph accented characters (instead of OT1's composite accents), required together with cmap for correct copy-paste

 %%%%%%%%% bibliography %%%%%%%%%
 \usepackage[style=numeric-comp,backend=biber]{biblatex} % tells LaTeX to use the biber tool instead of the traditional bibtex tool for sorting and formatting your bibliography. Biber is a more advanced and powerful tool than bibtex and it provides more features, such as advanced sorting, Unicode support and support for various data sources.
 \addbibresource{refs.bib} % add reference file, in the document, add \printbibliography to print bibliography

 %%%%%%%%% references (cite and glossary) %%%%%%%%%
 \makeatletter
 % some classes (e.g., beamer) loads hyperref by default. So it is sensible to check whether it wasn't already loaded to avoind clashes
 \@ifpackageloaded{hyperref}{
    % The package is already loaded
 }{
    % The package is not loaded, so load it now
    \usepackage[colorlinks=true,hyperindex=false]{hyperref} % make references blue and clickable
 }
 \makeatother
 \hypersetup{ % you can use allcolors=blue in hyperref options instead this setup
    linkcolor=black,          % For \gls{} entries
    citecolor=blue,          % For \cite{} entries
 }
 \usepackage{glossaries} % \newglossaryentry{} entries. ADJUST: If you want to make the glossary entries nonclickable, load this package before hyperref
 % CAVEAT: don't use `glossaries-extra`, otherwise the conditional glossary entry will not work! % SEE: https://tex.stackexchange.com/questions/98494/glossaries-dont-print-single-occurences/230664#230664
 \glsenableentrycount % enable \cgls, \cglspl, \cGls, \cGlspl
 % NOTE: use \cgls-based instead of \gls-based macros as the former puts the initials iff. it was used more than once.
 % HACK:
 % \glsentrylong{pll} -> long form

 % add hyphened entries
 % SEE: https://tex.stackexchange.com/a/311882/211183
 \glsaddkey
    {hyphenated}        % new key
    {\relax}            % default value if "hyphenated" isn't used in \newglossaryentry
    {\cglsentryhyph}     % analogous to \cglsentrytext
    {\cGlsentryhyph}     % analogous to \cGlsentrytext
    {\cglshyph}          % analogous to \cglstext
    {\cGlshyph}          % analogous to \cGlstext
    {\cGLShyph}          % analogous to \cGLStext

 \let\origcglshyph\cglshyph
 \renewcommand{\cglshyph}[1]{%
    \glsadd{#1}% mark used for glossary inclusion
    \origcglshyph{#1}% original hyphenated display
    % mark a flag macro for this label
    \expandafter\gdef\csname glsHyphUsed@#1\endcsname{1}%
 }
 % preserve original \cgls and override to consult the hyphen flag
 \let\origcgls\cgls
 \renewcommand{\cgls}[1]{%
    \ifcsname glsHyphUsed@#1\endcsname
        \glsentryshort{#1}% print short form if hyphenated use occurred
    \else
        \origcgls{#1}% otherwise use original behaviour
    \fi
 }

 %%%%%%%%% list of authors %%%%%%%%%
 \makeatletter
 \@ifclassloaded{beamer}{}{%
    \usepackage{authblk} % CAVEAT: this pkg will lead to compilation errors if you use it along with `\IEEEauthorblockN`, which is a command from the `IEEEtran` document class
 }
 \makeatother

 %%%%%%%%% items, tables and figs %%%%%%%%%
 \makeatletter
 % only load enumitem if not already present (sbrt.cls provides \labelindent)
 \@ifpackageloaded{enumitem}{}{\@ifundefined{labelindent}{\usepackage{enumitem}}{}}
 \makeatother
 \usepackage{xltabular}
 \usepackage{float} % use the [H] option
 \usepackage{tikz}
 \usepackage{graphicx} % extends the basic LaTeX graphic capabilities: placement, scaling, rotation, file formats
 \usepackage{svg} % \includesvg{}; % NOTE: requires inkscape and compilation with --shell-escape
 \usepackage{subcaption} % provides a means of using the subfigures environment, allowing a figure to be subdivided into smaller parts
 \usepackage{standalone} % place tikz environments or other material in own source files

 %%%%%%%%% new features %%%%%%%%%
 \usepackage{xparse} % create commands with optional arguments or complex argument structures
 \usepackage{xstring} % testing a string's contents, extracting substrings, substitution of substrings

 %%%%%%%%% math %%%%%%%%%
 \newcommand\bmmax{0} \newcommand\hmmax{0} % fix the "Too many math alphabets used in version normal" error (see https://tex.stackexchange.com/a/243541/211183)
 \usepackage{amsmath}
 \usepackage{mathtools} % is an extension package to amsmath to use \DeclarePairedDelimiter
 \usepackage{amsfonts}
 \usepackage{amssymb}
 \usepackage{esint} % provides extended integral symbols, giving you access to a wider variety of integral signs, such as double, triple, quadruple integrals
 % HACK:
 % \oiint -> contour integral
 \usepackage{newtxmath} % for Greek variants (bold, nonitalic, etc...). E.g., `\boldsymbol{\betaup}`
 \usepackage{stmaryrd} % provides new symbols, such as \llbracket \rrbracket
 \usepackage{bm} % for writing tensor, e.g., $\bm{\mathcal{A}}$
 % only load IEEEtrantools if the class did not already provide IEEEeqnarray
 \makeatletter
 \@ifpackageloaded{IEEEtrantools}{}{\@ifundefined{IEEEeqnarray}{\usepackage{IEEEtrantools}}{}}
 \makeatother
 \usepackage{siunitx} % typesetting units and unitless numbers SI (Système International d’Unités) units
 % CAVEAT: you cannot use siunitx for nonnumerical values, e.g. \qty{\pi}{\meter\per\second}
 % HACK:
 % \qty -> number and unit, e.g., \qty{10}{\meter\per\second}
 % \unit{} -> unit only, e.g., \unit{\meter\per\second}
 % Examples:
 % 1. \qtyrange[exponent-to-prefix=true, range-independent-prefix=true]{138e6}{2.9e9}{\hertz} -> 138 MHz to 2.9 GHz
 % use, possible options:
 % 1. "range-phrase=-" ->  change the word "to" to "--"
 % 2. range-units=single -> chage "1m to 10m" to "1 to 10m"
 % 3. mode=text % writes the unit in full
 % 4. quantity-product={-} to create a compound adjective with quantities, e.g. "the 50-Hz signal..."
 % use the [per-mode=symbol] option in the \unit or \qty command to change the writing of \per, or change the line below to set it globally
 \sisetup{per-mode=symbol} % print the symbol "/" in "25/100"
 \sisetup{tight-spacing=true} % makes the spacing in "5 x 10²" closer
 % \squared -> ^2

 \usepackage{physics} % several math macros, such as
 \AtBeginDocument{\RenewCommandCopy\qty\SI} % CAVEAT: avoid incompatibilities between physics and siunitx packages when using the \qty{}{} command. The conflict happens because it is defined in both packages. Although physics has \SI{}{} as an alternative, it is deprecated and therefore you should use \unit{} and \qty{}{} instead of \si{} and \SI{}{}, respectively. See here (https://tex.stackexchange.com/questions/628183/how-to-avoid-qty-conflict-with-physics-and-siunitx) for more info.
 % HACK:
 % \tr -> trace
 % \rank -> rank
 % \expval -> angle brackets to inner product,〈a,b〉, or ensemble average〈s(t)〉
 % \abs -> |x|
 % \norm -> ||x||
 % \eval -> evaluated bar x|_y=a
 % \order -> Big-O notation
 % \Re -> real
 % \Im -> imaginary
 % \dd[]{} -> differential
 % \dv -> derivative
 % \pdv -> partial derivative

 # Make considers targets that correspond to filenames to be up-to-date if the file exists and its modification time is later than that of its prerequisites. However, sometimes you may want to define targets that do not correspond to actual files, but rather perform some action such as cleaning up a build directory or running tests. These are called "phony" targets.

 # The reason why the command expansion $(command) is not working in your Makefile is because it is not being evaluated by the shell, but by Make itself. In Make, the $ character has a special meaning and is used to reference variables, so when you write $(command) in your Makefile, Make thinks you are trying to reference a variable called command and not running the command command. double dollar sign ($$) forces shell to run this command, $(shell command) also works

 # By default, the shell interpreter used by a Makefile is /bin/sh. However, you can change the shell interpreter that must run the Makefile by setting the SHELL variable at the beginning of the Makefile. When you use := to define a variable with a shell command, like MY_VAR := $(shell date), the command is evaluated immediately and the result is stored as a simple string. The value of the variable is not re-evaluated every time it is used in a command. That is, it is evaluated only once.

 # the "-" operator to ignore the exit status of the command and let the rule. When you have a conditional statement without an else and it return false (1 or more), it is not handled by the shell and is returned to the Makefile, which in turn stop the procedure. the "-" at the beginning of the command make Makefile ignore it
