Latex macros in Jupyter Lab #207
Description
So this would work?
<div hidden>
\newcommand{\require}[1]{}
$\require{begingroup}\require{newcommand}$
$\gdef\vec#1{\boldsymbol{#1}}$

The above approach did not work for me when trying to export as PDF.
I have since tried many other approaches, and the one that happened to work by some miracle is this:
<div hidden>
\[
\iffalse \textrm{General purpose macros} \fi
\renewcommand{\deg}{{^{\circ}}}
\newcommand{\rbr}[1]{{\left({{#1}}\right)}}
\newcommand{\abr}[1]{{\left\langle{{#1}}\right\rangle}}
\newcommand{\cbr}[1]{{\left\{{{#1}}\right\}}}
\newcommand{\sbr}[1]{{\left[{{#1}}\right]}}
\newcommand{\pipe}[1]{{\left|{{#1}}\right|}}
\newcommand{\ppipe}[1]{{\left\|{{#1}}\right\|}}
\newcommand{\floor}[1]{{\left\lfloor{{#1}}\right\rfloor}}
\newcommand{\ceil}[1]{{\left\lceil{{#1}}\right\rceil}}
\newcommand{\set}[1]{{ \cbr{{#1}} }}
\iffalse \textrm{Semantics macros} \fi
\newcommand{\iet}[3]{{\textrm{if } {{#1}} \textrm{ then } {{#2}} \textrm{ else } {{#3}}}}
\renewcommand{\t}[1]{{\textrm{true}}}
\newcommand{\f}[1]{{\textrm{false}}}
\iffalse \textrm{Compiler Construction macros} \fi
\newcommand{\fst}[1]{{\textrm{FIRST}({{#1}})}}
\newcommand{\flw}[1]{{\textrm{FOLLOW}({{#1}})}}
\newcommand{\gen}[2][]{{ {{#1}} \implies {{#2}} }}
\]
</div>I have no idea why this works and the other approaches don't, but in case anyone is looking for a quick and dirty fix, there you go.
Also, note that there can be no line breaks between the lines or this won't work.
You will need to shut down the notebook and restart it after adding the macros and it should work.
