1 2This is the C indenter, it originally came from the University of Illinois 3via some distribution tape for PDP-11 Unix. It has subsequently been 4hacked upon by James Gosling @ CMU. It isn't very pretty, and really needs 5to be completely redone, but it is probably the nicest C pretty printer 6around. 7 8Further additions to provide "Kernel Normal Form" were contributed 9by the folks at Sun Microsystems. 10 11++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 12> From mnetor!yunexus!oz@uunet.UU.NET Wed Mar 9 15:30:55 1988 13> Date: Tue, 8 Mar 88 18:36:25 EST 14> From: yunexus!oz@uunet.UU.NET (Ozan Yigit) 15> To: bostic@okeeffe.berkeley.edu 16> Cc: ccvaxa!willcox@uunet.UU.NET, jag@sun.com, rsalz@uunet.UU.NET 17> In-Reply-To: Keith Bostic's message of Tue, 16 Feb 88 16:09:06 PST 18> Subject: Re: Indent... 19 20Thank you for your response about indent. I was wrong in my original 21observation (or mis-observation :-). UCB did keep the Illinois 22copyright intact. 23 24The issue still is whether we can distribute indent, and if we can, which 25version. David Willcox (the author) states that: 26 27| Several people have asked me on what basis I claim that indent is in 28| the public domain. I knew I would be sorry I made that posting. 29| 30| Some history. Way back in 1976, the project I worked on at the 31| University of Illinois Center for Advanced Computation had a huge 32| battle about how to format C code. After about a week of fighting, I 33| got disgusted and wrote a program, which I called indent, to reformat C 34| code. It had a bunch of different options that would let you format 35| the output the way you liked. In particular, all of the different 36| formats being championed were supported. 37| 38| It was my first big C program. It was ugly. It wasn't designed, it 39| just sort of grew. But it pretty much worked, and it stopped most of 40| the fighting. 41| 42| As a matter of form, I included a University of Illinois Copyright 43| notice. However, my understanding was that, since the work was done 44| on an ARPA contract, it was in the public domain. 45| 46| Time passed. Some years later, indent showed up on one of the early 47| emacs distributions. 48| 49| Later still, someone from UC Berkeley called the UofI and asked if 50| indent was in the public domain. They wanted to include it in their 51| UNIX distributions, along with the emacs stuff. I was no longer at the 52| UofI, but Rob Kolstad, who was, asked me about it. I told him I didn't 53| care if they used it, and since then it has been on the BSD distributions. 54| 55| Somewhere along the way, several other unnamed people have had their 56| hands in it. It was converted to understand version 7 C. (The 57| original was version 6.) It was converted from its original filter 58| interface to its current "blow away the user's file" interface. 59| The $HOME/.indent.pro file parsing was added. Some more formatting 60| options were added. 61| 62| The source I have right now has two copyright notices. One is the 63| original from the UofI. One is from Berkeley. 64| 65| I am not a lawyer, and I certainly do not understand copyright law. As 66| far as I am concerned, the bulk of this program, everything covered by 67| the UofI copyright, is in the public domain, and worth every penny. 68| Berkeley's copyright probably should only cover their changes, and I 69| don't know their feelings about sending it out. 70 71In any case, there appears to be none at UofI to clarify/and change 72that copyright, but I am confident (based on the statements of its 73author) that the code, as it stands with its copyright, is 74distributable, and will not cause any legal problems. 75 76Hence, the issue reduces to *which* one to distribute through 77comp.sources.unix. I would suggest that with the permission of you 78folks (given that you have parts copyrighted), we distribute the 4.3 79version of indent, which appears to be the most up-to-date version. I 80happen to have just about every known version of indent, including the 81very original submission from the author to a unix tape, later the 82G-Emacs version, any 4.n version, sun version and the Unipress 83version. I still think we should not have to "go-back-in-time" and 84re-do all the work you people have done. 85 86I hope to hear from you as to what you think about this. You may of 87course send 4.3 version to the moderator directly, or you can let me 88know of your permission, and I will send the sources, or you can let 89me know that 4.3 version is off-limits, in which case we would probably 90have to revert to an older version. One way or another, I hope to get 91a version of indent to comp.sources.unix. 92 93regards.. oz 94 95cc: ccvaxa!willcox 96 sun.com!jar 97 uunet!rsalz 98 99
