Who wrote XEmacs?

XEmacs is the result of the time and effort of many people, and the active developers have changed over time. There are two major components of the XEmacs effort -- writing the code itself and providing all the support work (testing the code, releasing beta and final versions, handling patches, reading bug reports, maintaining the web site, managing the mailing lists, etc. etc.). Neither component would work without the other.

For a list of all XEmacs contributors, see XEmacs Contributors.

CODING

The primary code contributor over the years has been Ben Wing (active since late 1992). Between 1991 and 1995, large amounts of coding was contributed by Jamie Zawinski and Chuck Thompson. Many other people have authored major subsystems or otherwise contributed large amounts of code, including Andy Piper, Hrvoje Niksic, Jerry James, Jonathan Harris, Kyle Jones, Martin Buchholz, Michael Sperber, Olivier Galibert, Richard Mlynarik, Stig, William M. Perry and plenty of others.

Primary XEmacs-specific subsystems and their authors:

Objects

  • Conversion from 26-bit to 28-bit pointers and integers, lrecords, lcrecords: Richard Mlynarik, 1994
  • Conversion to 32-bit pointers and 31-bit integers: Kyle Jones, Martin Buchholz
  • Portable dumper, object descriptions: Olivier Galibert
  • KKCC (new garbage collector), ephemerons, weak boxes: Michael Sperber and students
  • Random object work (object equal and hash methods, weak lists, lcrecord lists, bit vectors, dynarr, blocktype, opaque, string resizing): Ben Wing
  • Profiling: Ben Wing
  • Some byte-compilation and hash-table improvements: Martin Buchholz
  • Bignum: Jerry James

Internationalization/Mule

I/O

  • Basic event/event-stream implementation: Jamie Zawinski

The recent overlapping dates are intentional, since two or three trees are maintained simultaneously at any point.
