Notes on sjacket
Raw
sjacket.markdown

Returning to sjaket after 18 months, here are my first reactions:

  • The code could be worse given it was a talk-driven development and that Mr. Edmund Jackson forced me to drink too many beers.
  • Today I tried implementing selections so that code can work on more than one expression:
    • they are several kind of selections:
      • raw selections
      • structuraly valid selections
      • structuraly valid antiselections (selections which when suppressed yield a valid structure, eg (a |b) (c| d))
    • is a position a collapsed selection?
    • insertion points are still missing when dealing with zippers: you can't be around nodes
  • how to insert spaces?
  • how to fix spacing? (coalescing)
