2011-05-04 blanchet 2011-05-04 exploit inferred monotonicity
2011-05-01 blanchet 2011-05-01 shorten readable names -- they can get really long with monomorphization, which actually slows down the ATPs
2010-11-26 wenzelm 2010-11-26 make two copies (!) of Library.UnequalLengths coincide with ListPair.UnequalLengths;
2010-11-20 wenzelm 2010-11-20 renamed raw "explode" function to "raw_explode" to emphasize its meaning;
2010-11-03 blanchet 2010-11-03 standardize on seconds for Nitpick and Sledgehammer timeouts
2010-09-05 wenzelm 2010-09-05 turned show_sorts/show_types into proper configuration options;
2010-09-03 wenzelm 2010-09-03 turned show_all_types into proper configuration option;
2010-08-23 blanchet 2010-08-23 perform eta-expansion of quantifier bodies in Sledgehammer translation when needed + transform elim rules later; it's a mistake to transform the elim rules too early because then we lose some info, e.g. "no_atp" attributes
2010-08-06 blanchet 2010-08-06 local versions of Nitpick.register_xxx functions
2010-08-05 blanchet 2010-08-05 fiddle with specialization etc.
2010-08-05 blanchet 2010-08-05 fix bug in Nitpick's "equationalize" function (the prems were ignored) + make it do some basic extensionalization
2010-08-03 blanchet 2010-08-03 better "Pretty" handling
2010-07-27 blanchet 2010-07-27 remove unused fun
2010-06-01 blanchet 2010-06-01 honor xsymbols in Nitpick
2010-06-01 blanchet 2010-06-01 added "atoms" option to Nitpick (request from Karlsruhe) + wrap Refute. functions to "nitpick_util.ML"
2010-04-29 blanchet 2010-04-29 expand combinators in Isar proofs constructed by Sledgehammer; this requires shuffling around a couple of functions previously defined in Refute
2010-04-27 blanchet 2010-04-27 remove Nitpick functions that are now implemented in Sledgehammer
2010-04-24 blanchet 2010-04-24 remove type annotations as comments; Nitpick is now 1136 lines shorter
2010-04-23 blanchet 2010-04-23 stop referring to Sledgehammer_Util stuff all over Nitpick code; instead, redeclare any needed function in Nitpick_Util as synonym for the Sledgehammer_Util function of the same name
2010-03-23 blanchet 2010-03-23 leverage code now in Sledgehammer
2010-03-19 blanchet 2010-03-19 move the Sledgehammer Isar commands together into one file; this will make easier to add options and reorganize them later
2010-03-17 blanchet 2010-03-17 added support for "specification" and "ax_specification" constructs to Nitpick
2010-02-25 blanchet 2010-02-25 improved precision of infinite "shallow" datatypes in Nitpick; e.g. strings used for variable names, instead of an opaque type
2010-02-22 blanchet 2010-02-22 fixed a few bugs in Nitpick and removed unreferenced variables
2010-02-18 blanchet 2010-02-18 added support for nonstandard "nat"s to Nitpick and fixed bugs in binary "nat"s and "int"s
2010-02-02 blanchet 2010-02-02 added support for nonstandard models to Nitpick (based on an idea by Koen Claessen) and did other fixes to Nitpick
2010-01-20 blanchet 2010-01-20 some work on Nitpick's support for quotient types; quotient types are not yet in Isabelle, so for now I hardcoded "IntEx.my_int"
2009-12-17 blanchet 2009-12-17 added support for binary nat/int representation to Nitpick
2009-12-08 blanchet 2009-12-08 made Nitpick work also for people who import "Plain" instead of "Main"
2009-12-04 blanchet 2009-12-04 fixed paths in Nitpick's ML file headers
2009-11-13 blanchet 2009-11-13 removed a few global names in Nitpick (styp, nat_less, pairf)
2009-10-27 blanchet 2009-10-27 internal renaming in Nitpick and fixed Kodkodi invokation on Linux; renamed Nitpick's ML structures from NitpickXxx to Nitpick_Xxx and added KODKODI_JAVA_LIBRARY_PATH to LD_LIBRARY_PATH before invoking Kodkodi
2009-10-22 blanchet 2009-10-22 added Nitpick's theory and ML files to Isabelle/HOL; the examples and the documentation are on their way.
