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.

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

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

Settings

Save Data Path

This setting allows you to change the location of where your drawings and drawing data should be saved.

Shortcuts

The Shortcuts setting lets you input custom commands to be translated into LaTeX when input into the math blocks.

{
  "op":"COMMAND",
  "format":"LATEX"
}

You can also pass parameters to the shortcuts, using %s1% or %s2% to denote the character or group directly before or after the shortcut.

{
  "op":"/",
  "format":"\frac{%s1%}{%s2%}"
}

This shortcut makes it so whenever you type / it will get the character or group directly before it, and put it into fraction format. ie. 3/17 would turn into \frac{3}{17} and {x-5a}/2 would turn into \frac{x-5a}{2}. All shortcuts must remain in proper JSON format.

Use the update button to apply your shortcut changes.
