 Definitions for troff: Virtual Entity of Relevant Acronyms (Version 1.9, June 2002)
:
TROFF
Typesetter New Run-OFF (Unix)
Jargon File (4.3.1, 29 Jun 2001)
:
troff /T'rof/ or /trof/ n.[Unix] The gray eminence of Unix text
processing; a formatting and phototypesetting program, written
originally in PDP-11 assembler and then in barely-structured early C by
the late Joseph Ossanna, modeled after the earlier ROFF which was in
turn modeled after the Multics and CTSS program RUNOFF by Jerome
Saltzer (_that_ name came from the expression "to run off a copy"). A
companion program, nroff, formats output for terminals and line
printers.
In 1979, Brian Kernighan modified troff so that it could drive
phototypesetters other than the Graphic Systems CAT. His paper
describing that work ("A Typesetter-independent troff," AT&T CSTR #97)
explains troff's durability. After discussing the program's "obvious
deficiencies -- a rebarbative input syntax, mysterious and undocumented
properties in some areas, and a voracious appetite for computer
resources" and noting the ugliness and extreme hairiness of the code and
internals, Kernighan concludes:
None of these remarks should be taken as denigrating Ossanna's
accomplishment with TROFF. It has proven a remarkably robust
tool, taking unbelievable abuse from a variety of preprocessors
and being forced into uses that were never conceived of in the
original design, all with considerable grace under fire.
The success of {TeX} and desktop publishing systems have reduced
`troff''s relative importance, but this tribute perfectly captures the
strengths that secured `troff' a place in hacker folklore; indeed, it
could be taken more generally as an indication of those qualities of
good programs that, in the long run, hackers most admire.
