  function FT(A, N, φ) {
    φ = φ || 0;
    return function(x) {
      var n = -1, y = 0;
      while (++n < N) {
        y += A[n] * Math.sin(τ * (n + 1) * x + φ);
      }
      return y;
    }
  }
hehe, seems annoying to type. Copy&paste everytime one of them is needed?


In Vim using digraphs:

    Ctrl-K f *   →   φ
    Ctrl-K t *   →   τ
In general:

    Ctrl-K <latin letter> * → <greek equivalent>


I love Vim's digraphs!

In emacs it's

    C-| tex
then

    \phi → φ
etc, which can be quite a bit more typing but can be easier to remember if you already know the TeX instructions for everything.

Now we just need to convince other editors to add something similar...


I think you mean C-u C-\ and then change the input type to tex.

There are other ways of inputting digraphs: C-x 8 RET lets you enter the name of any unicode symbol.

I wrote about the many ways of inputting digraphs and unicode here:

You're right, thanks. But C-u doesn't seem to be necessary, unless I have a strange setup.
