clarified raw_blast, which is not really a tactic since it operates directly on subgoal 1 without bounds check (cf. c46107e6714b); uniform handling of exceptions in depth_tac and blast_tac, discontinued separate blast_depth_tac; tuned blast_tac: atomize prems only once, outside DEEPEN;

clarified special incr_type_indexes;

tuned signature: Name.invent and Name.invent_names;

modernized structure ProofContext;

even more robust \isaspacing;

simplified Name.variant -- discontinued builtin fold_map;

some attempts at robust \isaspacing so that \isa{...} can be used in section headings etc. (need to avoid `\? for some reason);

discontinued Name.variant to emphasize that this is old-style / indirect;

prefer new-style Name.invents;

more tight name invention -- avoiding old functions;

\frenchspacing for formal isabelle style avoids extra space in situations like ``@{text "?"}'' followed by plain text;

tuned;

NEWS

correcting import theory of examples

fixing code generation test

removing char setup

removing unneccessary manual instantiations and dead definitions; hiding more constants and facts

adding a nicer error message for quickcheck_narrowing; hiding fact empty_def

adding narrowing engine for existentials

adapting Quickcheck_Narrowing: adding setup for characters; correcting import statement

adding theory Quickcheck_Narrowing to HOL-Main image

adapting IsaMakefile

moving Quickcheck_Narrowing from Library to base directory

compilation of Haskell in its own target for Quickcheck; passing options by arguments in Narrowing_Generators

local simp rule in List_Cset

tuning

compile

cleaner fact freshening, which also works in corner cases, e.g. if two backquoted facts have the same name (but have different variable indices)

added a really fully typed translation as a fallback for Metis, in rare cases where Metis correctly proves a theorem but has type-unsound steps in it (which is likelier to happen with some of the lighter translations)

improve sort inference in Metis proofs -- in some rare cases Metis steals Isabelle's variable names and the sorts must then be inferred as well

removed needless function that duplicated standard functionality, with a little unnecessary twist

removed more dead code

be a bit more liberal with respect to the universal sort -- it sometimes help

renamed "untyped_aconv" to distinguish it clearly from the standard "aconv_untyped"

merged

avoid duplicate facts, which confuse the minimizer output

pass Metis facts and negated conjecture as facts, with (almost) correctly set localities, so that the correct encoding is used for nonmonotonic occurrences of infinite types

restore comment about subtle issue

made "query" type systes a bit more sound -- local facts, e.g. the negated conjecture, may make invalid the infinity check, e.g. if we are proving that there exists two values of an infinite type, we can use the negated conjecture that there is only one value to derive unsound proofs unless the type is properly encoded

don't launch the automatic minimizer for zero facts

don't generate unsound proof error for missing proofs

renamed option to avoid talking about seconds, since this is now the default Isabelle unit

fixed format selection logic for Waldmeister

better default type system for Waldmeister, with fewer predicates (for types or type classes)

simplified directory structure; recovered README.html;

simplified directory structure;

further jedit build option; misc tuning;

build jedit as part of regular startup script (in that case depending on jedit_build component); misc tuning and simplification;

updated headers;

moved sources -- eliminated Netbeans artifact of jedit package directory;

removed obsolete Netbeans project setup;

support fresh build of jars; prefer pushd/popd, to avoid unclarity about fail/exit within sub-shell;

more jvmpath wrapping for Cygwin;

more robust exception pattern General.Subscript;

pervasive Output operations;

modernized Proof_Context;

standardized header;

merged

updated SMT certificates
