MatRepl
- is a Matrix
- and a repl: Read–Eval–Print Loop, where Print is doing operations on vectors and matrices in a graphic environment
- written in vanilla javascript (ES6)
The repl has the following syntax (It's work in progress, new capabilities will be added)
- arithmetic expressions:
- add, subtract, divide, multiply
- variable declaration eg: a= ...
- vector(1,2,3,4) adds a vector
-
> vector@0{x0:1, y0: 2, x:3, y:4}
-
- remove(x) removes bindings (when it's an object (eg vector), removes it from the matrix)
- remove(@x) removes an object using it's assigned index
- method calls:
- a = vector(0,0,12,1)
> vector@0{x0:1, y0: 2, x:12, y:1}
- a.type()
> vector
- property lookup
- a.x+1
> 13
To run locally
- make sure you have node/npm
- cmdline: npm run start
- enter the following:
a=vector(0,0,0.5,0.5) b=vector(0,0,-1,1) c="a+b" - and press enter
- or type help()
