Listed below are all of the tasks on Rosetta Code which have been solved using TMG.

TMG (from transmogrifier) is an early compiler-compiler introduced by Robert McClure in the mid-1960s. Later it was ported and further developed by Doug McIlroy of Bell Labs to work on microcomputers PDP-7 and PDP-11 under the UNIX operating system. McIlroy's dialect of TMG (the Unix TMG) was included into the UNIX operating system from Version 2 to Version 6. It was the first high-level programming language running on UNIX.

TMG was used to implement:

TMG influenced:

  • B (via Unix TMG)
  • TROL (Translation-Oriented Language) of Donald Knuth
  • YACC


There are two ways to run Unix TMG on modern computers:

  • by using a PDP-11 emulator with the original Unix V6 image
  • by running a modern port of Unix TMG
