9b50d902SRodney W. GrimesThis is the C indenter, it originally came from the University of Illinois
9b50d902SRodney W. Grimesvia some distribution tape for PDP-11 Unix.  It has subsequently been
9b50d902SRodney W. Grimeshacked upon by James Gosling @ CMU.  It isn't very pretty, and really needs
9b50d902SRodney W. Grimesto be completely redone, but it is probably the nicest C pretty printer
9b50d902SRodney W. Grimesaround.

9b50d902SRodney W. GrimesFurther additions to provide "Kernel Normal Form" were contributed
9b50d902SRodney W. Grimesby the folks at Sun Microsystems.

9b50d902SRodney W. Grimes
9b50d902SRodney W. GrimesThank you for your response about indent. I was wrong in my original
9b50d902SRodney W. Grimesobservation (or mis-observation :-). UCB did keep the Illinois
9b50d902SRodney W. Grimescopyright intact.
9b50d902SRodney W. Grimes
9b50d902SRodney W. GrimesThe issue still is whether we can distribute indent, and if we can, which
9b50d902SRodney W. Grimesversion. David Willcox (the author) states that:
9b50d902SRodney W. Grimes
9b50d902SRodney W. Grimes| Several people have asked me on what basis I claim that indent is in
9b50d902SRodney W. Grimes| the public domain.  I knew I would be sorry I made that posting.
9b50d902SRodney W. Grimes|
9b50d902SRodney W. Grimes| Some history.  Way back in 1976, the project I worked on at the
9b50d902SRodney W. Grimes| University of Illinois Center for Advanced Computation had a huge
9b50d902SRodney W. Grimes| battle about how to format C code.  After about a week of fighting, I
9b50d902SRodney W. Grimes| got disgusted and wrote a program, which I called indent, to reformat C
9b50d902SRodney W. Grimes| code.  It had a bunch of different options that would let you format
9b50d902SRodney W. Grimes| the output the way you liked.  In particular, all of the different
9b50d902SRodney W. Grimes| formats being championed were supported.
9b50d902SRodney W. Grimes|
9b50d902SRodney W. Grimes| It was my first big C program.  It was ugly.  It wasn't designed, it
9b50d902SRodney W. Grimes| just sort of grew.  But it pretty much worked, and it stopped most of
9b50d902SRodney W. Grimes| the fighting.
9b50d902SRodney W. Grimes|
9b50d902SRodney W. Grimes| As a matter of form, I included a University of Illinois Copyright
9b50d902SRodney W. Grimes| notice.  However, my understanding was that, since the work was done
9b50d902SRodney W. Grimes| on an ARPA contract, it was in the public domain.
9b50d902SRodney W. Grimes|
9b50d902SRodney W. Grimes| Time passed.  Some years later, indent showed up on one of the early
9b50d902SRodney W. Grimes| emacs distributions.
9b50d902SRodney W. Grimes|
dc51023cSPhilippe Charnier| Later still, someone from UC Berkeley called the UofI and asked if
9b50d902SRodney W. Grimes| indent was in the public domain.  They wanted to include it in their
9b50d902SRodney W. Grimes| UNIX distributions, along with the emacs stuff.  I was no longer at the
9b50d902SRodney W. Grimes| UofI, but Rob Kolstad, who was, asked me about it.  I told him I didn't
9b50d902SRodney W. Grimes| care if they used it, and since then it has been on the BSD distributions.
9b50d902SRodney W. Grimes|
9b50d902SRodney W. Grimes| Somewhere along the way, several other unnamed people have had their
9b50d902SRodney W. Grimes| hands in it.  It was converted to understand version 7 C.  (The
9b50d902SRodney W. Grimes| original was version 6.)  It was converted from its original filter
9b50d902SRodney W. Grimes| interface to its current "blow away the user's file" interface.
9b50d902SRodney W. Grimes| The $HOME/.indent.pro file parsing was added.  Some more formatting
9b50d902SRodney W. Grimes| options were added.
9b50d902SRodney W. Grimes|
9b50d902SRodney W. Grimes| The source I have right now has two copyright notices.  One is the
9b50d902SRodney W. Grimes| original from the UofI.  One is from Berkeley.
9b50d902SRodney W. Grimes|
9b50d902SRodney W. Grimes| I am not a lawyer, and I certainly do not understand copyright law.  As
9b50d902SRodney W. Grimes| far as I am concerned, the bulk of this program, everything covered by
9b50d902SRodney W. Grimes| the UofI copyright, is in the public domain, and worth every penny.
9b50d902SRodney W. Grimes| Berkeley's copyright probably should only cover their changes, and I
9b50d902SRodney W. Grimes| don't know their feelings about sending it out.
9b50d902SRodney W. Grimes
dc51023cSPhilippe CharnierIn any case, there appears to be none at UofI to clarify/and change
9b50d902SRodney W. Grimesthat copyright, but I am confident (based on the statements of its
9b50d902SRodney W. Grimesauthor) that the code, as it stands with its copyright, is
9b50d902SRodney W. Grimesdistributable, and will not cause any legal problems.
9b50d902SRodney W. Grimes
9b50d902SRodney W. GrimesHence, the issue reduces to *which* one to distribute through
9b50d902SRodney W. Grimescomp.sources.unix. I would suggest that with the permission of you
9b50d902SRodney W. Grimesfolks (given that you have parts copyrighted), we distribute the 4.3
9b50d902SRodney W. Grimesversion of indent, which appears to be the most up-to-date version. I
9b50d902SRodney W. Grimeshappen to have just about every known version of indent, including the
9b50d902SRodney W. Grimesvery original submission from the author to a unix tape, later the
9b50d902SRodney W. GrimesG-Emacs version, any 4.n version, sun version and the Unipress
9b50d902SRodney W. Grimesversion.  I still think we should not have to "go-back-in-time" and
9b50d902SRodney W. Grimesre-do all the work you people have done.
9b50d902SRodney W. Grimes
9b50d902SRodney W. GrimesI hope to hear from you as to what you think about this. You may of
9b50d902SRodney W. Grimescourse send 4.3 version to the moderator directly, or you can let me
9b50d902SRodney W. Grimesknow of your permission, and I will send the sources, or you can let
9b50d902SRodney W. Grimesme know that 4.3 version is off-limits, in which case we would probably
9b50d902SRodney W. Grimeshave to revert to an older version. One way or another, I hope to get
9b50d902SRodney W. Grimesa version of indent to comp.sources.unix.
