NB. Core logic for a tiny editor in J.
NB. No select/copy/paste (in this gist), but it does support multiple cursors.
NB. This started as the code for editing a single line of text, but I'm now
NB. using three copies simultaneously: one for a single token, one for
NB. boxed tokens on a line, and one for boxed lines in a buffer.
coclass 'ed'

init =: {{
  B =: ''  NB. the buffer to edit.
  C =: 0   NB. cursor position(s)
