I often use latex to write out scratch work, but I enjoy having lots of freedom when I write. Is there a way to have a document that expands as a write in any direction?
I've found that you can make a page that kinda has this feature using the standalone class
\documentclass[border=1in]{standalone}
\usepackage{lipsum}
\begin{document}
\begin{minipage}{21cm}
\lipsum[1-150]
\end{minipage}
\end{document}
Which generates a very long page of text.
After trying it out with a very basic example
\documentclass[border=1in]{standalone}
\begin{document}
\begin{equation}
x = 2
\end{equation}
\end{document}
I get the following error
You can't use `\eqno' in restricted horizontal mode.
So then this lead me this post which suggests to add the preview option, but then writing some scratchwork doesn't allow for horizontal expansion when the equations get long (it's cut off on the right):
\documentclass[border=1in, preview]{standalone}
\usepackage{amsmath, amssymb}
\begin{document}
\begin{equation}
\begin{bmatrix}
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\
a & s & d & f & g & h & j & k \\
l & p & o & i & u & y & t & r \\
e & w & q & z & x & c & v & b \\
n & m & k & l & o & i & j & y \\
6 & 4 & ds & 3 & t & y & g & d \\
t & vf & b & n & kj & 9 & 8 & 6 \\
r & d & 5 & f & 6 & f & 6 & f
\end{bmatrix}
\rightsquigarrow
\begin{bmatrix}
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\
a & s & d & f & g & h & j & k \\
l & p & o & i & u & y & t & r \\
e & w & q & z & x & c & v & b \\
n & m & k & l & o & i & j & y \\
6 & 4 & ds & 3 & t & y & g & d \\
t & vf & b & n & kj & 9 & 8 & 6 \\
r & d & 5 & f & 6 & f & 6 & f
\end{bmatrix}
\rightsquigarrow
\begin{bmatrix}
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\
a & s & d & f & g & h & j & k \\
l & p & o & i & u & y & t & r \\
e & w & q & z & x & c & v & b \\
n & m & k & l & o & i & j & y \\
6 & 4 & ds & 3 & t & y & g & d \\
t & vf & b & n & kj & 9 & 8 & 6 \\
r & d & 5 & f & 6 & f & 6 & f
\end{bmatrix}
\rightsquigarrow
\end{equation}
\end{document}
But removing the preview option allows for horizontal expansion but throws
you can't use \eqno in math mode
If anyone has an idea of how I can get a simple page that expands with what I write it would be greatly appreciated!
