Diagon

Diagon is an interactive interpreter. It transforms markdown-style expression into an ascii-art representation.

It is written in C++ and use WebAssembly, HTML and CSS to make a Web Application. We also expose a command line interface, for personal and 3rd party tools.

Command line interface

Diagon is also usable as a command line tool. For instance:

echo "1+1/2 + sum(i,0,10) = 113/2" | diagon Math
            10         
          ___        
      1   ╲       113
  1 + ─ + ╱   i = ───
      2   ‾‾‾      2 
           0

To use it, you can either compile it from source or use the precompiled binaries published on the snapstore:

sudo snap install diagon
