This is an Obsidian plugin for taking math notes using Excalidraw.

Last update: Dec 30, 2022

Overview

Obsidian Math+

Obsidian Math+ is a plugin for taking math notes quickly and efficiently.

Usage

Run the Insert math block command, either using the command pallet or cmd + M. This will create a math block for you to start taking notes in, you can write these notes using LaTex, or just write the equations out intuitively, and they will be parsed to the best of this plugin's ability.

$rendered equation$

Now that your notes have been rendered, you can go into draw mode by clicking the pen icon in the top right of the block. This opens up an Excalidraw instance over the math block so you can easily add freeform annotations.

Note: This only works in Live Preview Mode

$excalidraw$

To save your drawing, press the checkmark in the upper right corner, and your drawing will be rendered as an SVG.

$excalidraw svg$

Settings

Colors

Here you can change the three default colors you can pick from while taking notes, or turn on the color picker for customization on the fly.

Math Block Size

This allows you to change the size of the math blocks.

Comments

[FR]: Support custom color when drawing.

Pleasure support custom colore when I drawing. I have a problem when I drawing on light theme. I can't see because the line is white. And maybe it could open excalidraw file above the math block.

Why no mobile support?

If it's just a formatting think I'd just throw a disclaimer in the readme and enable it. As an iPad user having this kind of functionality on my tablet would be awesome. Regardless of that, this is an amazing plugin, thanks for making it!

$\oint is not rendered in the drawing$

\oint is not rendered in the drawing

\oint does not come in LaTeX by default, and has to be added using external packages. But Obsidian can render the symbol by default, and this plugin cannot.

According to this page, the package required for this symbol can be either of esint or wasysym.

$[Bug] \sum always renders with an m subscript?$

[Bug] \sum always renders with an m subscript?

renders as

I don't know why that m is there, but I can't write sums correctly because of that.

Another thing:

my excalidraw menu always renders horizontally, but I see it's vertical in the README screenshot. Is there a way to configure it like that?

Math+ causes Excalidraw UI to change

Whenever the Plugin is activated, the Excalidraw toolbar at the bottom of the screen gets stretched out across the entire screen. This unfortunately blocks most of the canvas. Deactivating Math+ and restarting Obsidian brings back the normal toolbar. Otherwise this plugin is absolutely amazing, thank you very very much.

[bug] fail to switch plugin

Add setting to change saved directory of drawings

Currently the drawings are saved in the plugin's folder. This might be an issue for users backing up just the contents of their vault as the svg drawings would be paired with the configuration files. A fix would be adding a field in settings to allow users to designate a folder within the vault to save the images to.

A rough example of what it might look like

Excalidraw "Keep selected tool active after drawing" icon not shown

Excalidraw has a feature that allows you to lock the current tool to be active and you can still do it here with the key bind q, however it is not shown in the UI

Current implementation:

This makes it hard to tell when a tool is locked and lacks the GUI button.

A possible fix could make it look like:

Excalidraw drawings overwrite each other on same note

Each new drawing I do overwrites the other ones within the same notes when I close and open Obsidian. There's also an issue where the Excalidraw instance blocks out the typed math, though I was able to resolve that for now by uninstalling and reinstalling the plugin.
