Abandoned

Since infogami has been abandoned by its creators, I’m out too. Back to web.fisher.cx for me. Everything that was here is there.

Do ranges overlap

If you register and log in you can add comments to my pages. If viewing the main blog page, click the # underneath an entry to comment on it.

To determine if two ranges overlap:

  • Lispy: (not (or (< end1 start2) (< end2 start1)))
  • Cish: !((end1 < start2) || (end2 < start1))

Assumptions:

  • The ranges are inclusive
  • (and (≤ start1 end1) (≤ start2 end2))
