Zulip also supports syntax highlighting of multi-line code blocks using
Pygments. To add syntax highlighting to a multi-line code
block, add the language's first
Pygments short name after the first set of
back-ticks; as you type out a code block's short name, a dropdown with short
name suggestions will appear.
Note: You can only specify the language's short name in fenced code
blocks. It is not possible to use the syntax highlighter in blocks
indented with spaces.
To insert quotes, you can either add a greater-than symbol
a space before your phrase or submit it as a quote block by following
the code syntax highlighting format.
You can display mathematical symbols, expressions and equations using Zulip's
TeX typesetting implementation,
based on KaTeX.
Visit the KaTeX Wiki
to view a complete of compatible commands.
Surround elements in valid TeX syntax with
$$two dollar signs$$ to display it
as inline content.
Also, you can show expressions, such as expanded integrals, in TeX
display mode to present them fully-sized in the center of the messages by
fencing them with three back-ticks
``` or tildes
~~~, with math,
tex or latex immediately after the first set of back-ticks.
