Renders LaTeX math formulas in Slack.
Similar to the Chrome extension math-with-slackb, except this plugin uses
the KaTeX library instead of MathJax for better compatibility with the

Usage instructions:
Mostly works like standard LaTeX.

Default delimiters are as follows (this avoids issues with dollar signs being used for other purposes):

Inline math:
$$..$$
$$..$$

Display math:
$..$
$$..$$$Alternatively, in the options of the extension one can also choose to work with the usual LaTeX delimiters: Inline math: $$..$$$ .. $Display math: $..$ $$..$$ Newlines in formulas can be inserted with \newline. Double backslash \\ is ignored. Blackboard bold letter shorthands: \R is short for \mathbb{R} \N is short for \mathbb{N} \Z is short for \mathbb{Z} Downloads: Firefox: https://addons.mozilla.org/nl/firefox/addon/latex-in-slack/ Chrome: https://chrome.google.com/webstore/detail/latex-in-slack/pfcfelfnpbnboelkjedecjipaibpnfja Troubleshooting: 1. Slack uses _ for _italics_ and * for *boldface*. This can interfere with your LaTeX formatting if your message has multiple underscores or asterisks in it. The developers of Slack are not big on having a consistent way to escape these special characters, but you can try: a) escaping using two backslashes: $$\bar\chi^{\\*}\\_W$$ A single backslash is interpreted by the LaTeX rendering library as part of a command, but two of them will be ignored. b) putting spaces around it: $$\bar\chi^ * _ W$$ 2. Sometimes Slack does something funny to double space " " making the plugin unable to recognize a piece of LaTeX that contains it, like $$\R$$. Plugin by Sophie Huiberts and Bento Natura (2019-2020). Option to choose$/$$/$$\$ delimiters added by Nicolas Boumal (2020).
