-- $LynxId: README.metrics,v 1.12 2014/02/13 23:56:42 tom Exp $ This is a short summary of code metrics showing how lynx has grown from release to release. It also shows how the original codebase has been almost completely replaced by contributors after the release of lynx 2.4.2 in 1996. The numbers shown are for lines of text, to keep the presentation simple.

Comparisons using the original source give lower estimates of untouched code, though either must be viewed taking into account insignificant similarities (such as blank lines). Starting in 2.8.6dev.3, all C source code has been routinely indented using the lnx-indent script from http://invisible-island.net/cindent/ Current lynx releases contain a large amount of text other than C code. That includes plain text, html, message libraries, custom and generated scripts. ------------------------------------------------------------------------------- Here is a count of contributions (from CHANGES and docs/CHANGES2.8) since the start of the 2.8 series: 0.5 AJL 3 Al Gilman 1 Alexei Anatski 2 Alexey Dobriyan 2 Andrew Belov 3.5 Andrey A Chernov 1 Arkadiusz Miskiewicz 1 Arnaud Giersch 2 Atsuhito Kohda 1 Bake Timmons 25.5 Bela Lubkin 1 Bill Nottingham 3.5 Bill Schiavo 2 Binh Do 1 Brett Lymn 46.3 Brian J Pardy 1 Carlton Anderson 1 Charles Karney 1 Chris Adams 1 Christian Hudon 1 Christian Jensen 3 Christian Weisgerber 1 Christoph J Gartmann 1 Chuck Houpt 1 Crouton 1 Dan Jacobson 1 Daniel Dickman 1 David Combs 1 David Henderson 0.5 David Woolley 1 Dick Wesseling 1 Diego Elio Petteno 129.7 Doug Kaufman 1 Duncan Simpson 2.5 Eduardo Chappa 2 Emanuele Giaquinta 1 Eric Brun 51 External 1 Fabian Fingerle 280.5 Foteos Macrides 2 Frank Heckenbach 4.3 Frederic L W Meunier 1 Frederick P Herrmann 1 Georg Drenkhahn 1 George Lindholm 22 Gisle Vanem 1 Glenn Nielsen 1 Hans Wurst 26.5 Hataguchi Takeshi 1 Heikki Kantola 0.5 Helen Sommer 23 Henry Nelson 1 Hiram Lester Jr 8.5 Hiroyuki Senshu 3 Hynek Med 0.3 Igor B Poretsky 84.8 Ilya Zakharevich 6.5 Ismael Cordeiro 2 J Kevin Ternes 1 Jacob Poon 27.5 James E Spath 1 Jamie Strandboge 1 Jan Hlavacek 2.5 Jason F McBrayer 1 Jean-Yves Levesque 1 Jeffrey C Honig 1 Jens Schmalzing 1 Jens Seidel 1 Jerome Lauret 2 Joey Schulze 0.3 Johannes Hromadka 35 John Bley 6 John E Davis 1 John Hawkinson 1 John Nowlin 2 Jonathan Sergent 1 Josef Sontgen 2 Julian Coleman 1 Kamil Dudka 3 Karl Eichwalder 1 Karl-Andre Skevik 3 Kihara Hideto 29.3 Kim DeVaughn 706.3 Klaus Weide 1 Lalo Martins 1 Larry Virden 15.8 Larry W Virden 11 Laura Eaves 342.3 Leonid Pauzner 1 Liam Davis 1 Marc Huber 0.3 Marek Kubita 2 Masashi Fujita 1 Masayasu Ishikawa 1 Masayuki Hatta 1 Matt Kraal 1 Michael Sobolev 6.5 Michael Warner 1 Michel Such 1 Mike Castle 2 Munechika Sumikawa 1 Nigel Horne 0.5 Nikos Chantziaras 1 OpenBSD CVS 1 Owen Leibman 1 Pat Walsh 13.5 Paul B Mahol 1 Paul D Smith 52.5 Paul Gilmartin 1 Peter Canning 1 Phil Pennock 27.3 Philip Webb 14 Philippe De Muyter 5.5 Rado Smiljanic 2 Ralph Babel 1 Randall 1 Risto Widenius 1 Rob Cameron 1 Ryan Nielsen 2 Scott Bigham 1 Sergej Kvachonok 6 Sergey Svishchev 1 Serhii Hlodin 15 Sinan Kaan Yerli 7.8 Stefan Caunter 1 Stepan Kasal 1 Tadayoshi Okuma 1 Takao Fujiwara 1 Thomas Braun 2030.3 Thomas E Dickey 0.5 Thomas Klausner 1 Thomas Viehmann 17 Thorsten Glaser 1 Tim Chase 4 Tim Larson 1 Timur Birsh 2 Tomas Vanhala 1.5 Ulf Harnhammar 6.5 Victor Schneider 2 Ville Herva 86 Vlad Harchev 37.5 Wayne Buttles 1 Wesley Morgan 1 Zdenek Prikryl 1.5 nsh@horae.dti.ne.jp 4355 Total ------------------------------------------------------------------------------- Older attributions are problematic for several reasons: + some contributors were not credited, + some changes were not recorded, + the level of importance of changes in the older logs differs noticeably from the newer logs. There is neither a source repository nor a mailing-list archive to consult to resolve these issues. However, some information can be gleaned from the existing change-logs to show the principal contributors for each release (i.e., not listing those with less than 1%): ** credits from CHANGES docs/CHANGES2.8 (4328.6 changes) 1.1 Brian J Pardy 3.0 Doug Kaufman 6.5 Foteos Macrides 2.0 Ilya Zakharevich 16.3 Klaus Weide 7.9 Leonid Pauzner 1.2 Paul Gilmartin 47.4 Thomas E Dickey 2.0 Vlad Harchev ** credits from CHANGES docs/CHANGES* (5795.6 changes) 2.3 Doug Kaufman 23.6 Foteos Macrides 1.5 Ilya Zakharevich 12.4 Klaus Weide 5.9 Leonid Pauzner 35.4 Thomas E Dickey 1.5 Vlad Harchev 3.6 unknown ** credits from CHANGES (3408.6 changes) 1.4 Brian J Pardy 3.5 Doug Kaufman 2.5 Ilya Zakharevich 1.0 John Bley 12.9 Klaus Weide 9.2 Leonid Pauzner 1.5 Paul Gilmartin 52.8 Thomas E Dickey 2.5 Vlad Harchev ** credits from docs/CHANGES2.8 (920 changes) 1.2 Doug Kaufman 30.5 Foteos Macrides 29.0 Klaus Weide 3.2 Leonid Pauzner 1.4 Philippe De Muyter 27.4 Thomas E Dickey 2.6 Wayne Buttles ** credits from docs/CHANGES2.7 (233 changes) 77.3 Foteos Macrides 3.4 Hiram Lester Jr 5.2 Klaus Weide 1.3 LWV 3.4 unknown ** credits from docs/CHANGES2.6 (240 changes) 83.8 Foteos Macrides 1.2 Klaus Weide 2.1 LWV 5.8 unknown ** credits from docs/CHANGES2.5 (554 changes) 1.3 DT 1.4 David Woolley 82.3 Foteos Macrides 4.7 unknown ** credits from docs/CHANGES2.4 (328 changes) 75.9 Foteos Macrides 3.0 GL 16.2 unknown ** credits from docs/CHANGES2.3 (112 changes) 1.8 David Trueman 1.8 Foteos Macrides 94.6 unknown
