What's this about?

This package ships a variety of unicode symbols commonly used by working mathematicians in a coherent syntax roughly based on LaTeX.

Why would I need this?

It is much easier to communicate about mathematics i.e. in a math discord or via email with a collaborator when you read statements like

π₋ₙ(map(Σ₊Y, 𝐇(A))) ⋍ Hⁿ(Y, A)

compared to the currently widely adopted

\pi_{-n}(map(\Sigma_{+}Y, \mathbf{H}(A))) \simeq \mathsf{H}^{n}(Y, A)

What's inside?

The basic syntax for maths symbols is :trigger:, where 'trigger' is the maths command in question. For example:

- ```:to:```     ⟶ ```⟶```
- ```:epi:```    ⟶ ```↠```
- ```:mono:```   ⟶ ```⮩``` 
- ```:infty:```  ⟶ ```∞```
- ```:calC:```   ⟶ ```𝓒```
- ```:Lambda:``` ⟶ ```Λ```
- ```X:_1:```    ⟶ ```X₁```

Here's an exhaustive list of symbols that are currently supported together with their trigger.
