When typing asterisk `*` after dollar sign ($) to indicate math, a duplicate * will appear

troth · 2020-09-20T02:56:20.451Z

Steps to reproduce

Type a math function and start the line with $ to indicate as such. For example:

$a = b * c$

Expected result

$a = b * c$

Actual result

$a = b * c$*

There will be an extra asterisk that shows up.

Environment

Operating system: Ubuntu 18.04

Obsidian version: 0.8.14

I can’t repro this. Can you post a short gif\video?

Ok, I think I get what you mean. Why would you wanna use * in a formula? I don’t recall ever using it. I think it’s pretty rare.

You can disable auto-completion for * if you want and it seems to happen only if there is whitespace before the star.

It’s the symbol for convolution:

Convolution

In mathematics (in particular, functional analysis) convolution is a mathematical operation on two functions (f and g) that produces a third function ( f ∗ g {\displaystyle f*g} ) expressing how the shape of one is modified by the other. The term convolution refers to both the result function and to the process of computing it. It is defined as the integral of the product of the two functions after one is reversed and shifted. And the in...

I would simply use \ast instead: $f \ast g$

This is a conflict with the Autopair markdown syntax preference I believe, turning it off you can still format things with bold/italics by selecting them and using a hotkey.

Upon further thinking, i don’t think this is a bug. Because, we have no way of knowing if you put a $ for dollar or a $ for starting a formula.

If you use a lot of convolutions, I would disable the auto-pair of *.

Thanks for the replies. I’m new to LaTeX and see that I should be using \times for multiplication. This can probably be closed. Yes, I do have auto-completion enabled.
