improvements to tikzjax

[benrbray]

When I have time, I would like to make a fork of drgrice1/tikzjax to address the following issues.

Possible Improvements

• Currently, the tikzjax document is only rendered when a <script type="tikz"> element is detected on the page. It would be great if there were a way to manually invoke the renderer, for more control.
• Override the default "loading spinner" provided by tikzjax.
• Add a way to control the attributes of the SVG output. For instance, a "scale" parameter to the rendering function which multiplies the width and height attributes of the SVG by a fixed amount.
• When there are TeX rendering errors, find a way to store them in a string rather than printing them line by line to the console. This would make it possible to display the errors to the user.
• Simplify the build process
• Make it easier to include custom *.sty files, such as quiver.sty from q.uiver.app
• some basic symbols & packages are missing, for example \ulcorner and \lrcorner for commutative diagrams

Useful Information

forks of tikzjax:

• here is the diff between drgrice/tizkzjax and the original kisonecat/tikzjax
  • the fork makes it possible to edit the preamble (the original just dropped straight into \begin{document}), thereby making tikzcd possible
• the author of aristicat1/obsidian-tikzjax also has a fork, aristicat1/tikzjax, see the diff
  • depends on aristicat1/dvi2html
  • the output-single-file branch seems to be the most up to date
