Greetings, Debian has a system called popularity-contest, which is an opt-in survey of package use. I was curious to see the ranking of darcs among Haskell implementations themselves. The results: Darcs ranks higher than ghc and hugs. #<name> is the package name; #<inst> is the number of people who installed this package; #<vote> is the number of people who use this package regularly; #<old> is the number of people who installed, but don't use this package # regularly; #<recent> is the number of people who upgraded this package recently; #<no-files> is the number of people whose entry didn't contain enough # information (atime and ctime were 0). #rank name inst vote old recent no-files (maintainer) 138 darcs 563 159 280 124 0 (Isaac Jones) (51) hugs 304 119 157 28 0 (Isaac Jones) 321 ghc6 194 81 80 33 0 (Ian Lynagh) Hugs is listed in a different category, so the ranking is off. Ian Lynagh pointed me at this nice graph showing the historical installation of the three packages: http://people.debian.org/~igloo/popcon-graphs/index.php?packages=ghc6,darcs,hugs&show_installed=on&want_percent=on&want_legend=on&beenhere=1 peace, isaac
