A chrome extension for rendering ascii math as unicode.
When installed, you can select text and then by clicking the extension, opening the context menu, or activing a hotkey, convery the text into unicode.
For example, hightling the following text (the example from ascii math):
sum_(i=1)^n i^3=((n(n+1))/2)^2
You'll convert it to:
∑ᵢ₌₁ⁿ i³=(ⁿ⁽ⁿ⁺¹⁾⁄₂)²
While not a perfect represention, this is more portable than an image, and can often be easier to read.
In the process of creating this, I wrote an ascii math parser from scratch.
Parser combinators had some issues differentiating symbols appropriately, and traditional CFGs had trouble with the greedy apporach to ascii math (e.g. it'll interpret sin ) as just the token sin with no argument, instead of failing to parse because it doesn't have an argument.
Most javascript CFGs also require specfying the grammar in a text file, which is somewhat obnoxious given the large symbol tables associated with ascii math.
Compile a local version for development testing
yarn build
Compile a zip for upload to the store
yarn pack
- It'd be nice to extend the rendering to multi-line support that works for fixed width fonts.
