\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{mkessler-mathfig}[2022/01/13 - Math figures with TikZ / pgfplots / xy]


% This is just a collection of the packages I use to typeset mathematical figures
% most commonly plots, commutative diagrams or geometry



\RequirePackage{pgfplots} % Plots
\pgfplotsset{compat=1.7}

\RequirePackage{tikz} % Plots / drawings
\usetikzlibrary{calc, intersections, through, quotes, angles, babel, positioning, snakes}

\RequirePackage{tikz-cd} %Commutative diagrams
\RequirePackage{xparse}


%%for small diagrams, similar to tikz-cd
\RequirePackage[all]{xy}        % for small diagrams, e.g. arrows
%%% In older versions, you found 
% \RequirePackage{xy}
% \xyoption{all}
% here, but this messes with the catcode of the @ sign (which no package should do!)
% so that further parts in this package would get broken


\newcommand\pushoutsymbol{\tikz[baseline=0.5,scale=0.2]{
        \draw[-] (0,0) --(0,1) -- (1,1);
    \draw (1,0) circle (1.5pt);}
}

\newcommand\pullbacksymbol{\tikz[baseline=0.5,scale=0.2]{
        \draw[-] (0,0) --(1,0) -- (1,1);
    \draw (0,1) circle (1.5pt);}
}

% This is used in a tikzcd
\NewDocumentCommand\pushout{ O{dr} }{
    \arrow[phantom, pos=0.45]{#1}{\pushoutsymbol}
}

% This is used in a tikzcd
\NewDocumentCommand\pullback{ O{dr} }{
    \arrow[phantom, pos=0.45]{#1}{\pullbacksymbol}
