                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
latest version of Slack.


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}

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 $$\R  $$.

Great plugin. One problem is that the recipient will need to install this plugin, too.

The LaTex in Slack extension is great, and makes it much easier to work with collaborators remotely!
