LaTeX in Slack

Render LaTeX in Slack chat.

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} 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).
